| 1 | 甘肃灵台黄土剖面记录地球磁场长期变化的可靠性探析显示文摘对甘肃灵台黄土/古土壤序列黄土层L1以及古土壤层SO和S1进行的较为详细的古地磁和岩石磁学研究表明:该剖面黄土剩余磁性在锁定过程中受到的平滑作用不大,因此能够记录百年尺度的地球磁场长期变化;而古土壤剩余磁性则受到强烈的平滑作用,不能记录百年尺度的地球磁场长期变化.在此基础上,对黄土层L1记录的地球磁场长期变化特征进行了分析,进一步证实了Mono Lake和Laschamp漂移是两个独立的事件。 | 朱日祥 郭斌 潘永信 刘青松 A.

| 2 | Friction Sensitivity of Nitramines. Part Ⅰ:Comparison with Impact Sensitivity and Heat of Fusion显示文摘Fractions of β-HMX(β-1,3,5,7-tetranitro-1,3,5,7-tetrazocane) have been used to demonstrate the mutual relationship between friction and impact sensitivities.Inclusion of an additional twelve nitramines into this scenario resulted in a series of partial relationships,which were determined from the molecular structure of these substances.It was also found that there is a relation between increasing heats of fusion of the nitramines studied and their decreasing friction sensitivities.Comparison of friction sensitivity with heats of fusion,ΔHm,tr of the studied nitramines shows that the increase in ΔHm,tr values is more or less connected with a decrease in friction sensitivity. | Marcela Jungová Svatopluk Zeman Adéla Husarová | 2011 | 含能材料2011，19，6： | 12 |

| 6 | Friction Sensitivity of Nitramines. Part Ⅱ:Comparison with Thermal Reactivity显示文摘The friction sensitivity(FS) of five linear and eight cyclic nitramines has been determined.Arrhenius parameters of non-autocatalyzed thermal decomposition of these nitramines were used for comparison of the FS values with thermal reactivity.Generally,increasing values of activation energies of non-autocatalyzed decomposition of the studied nitramines are connected with decreasing FS values.A similar trend was found in the relation between FS and hypothetical initiation temperature for 5% conversion of the nitramines after 50 μs of their thermolysis,however,if in the given series of nitramines their initiation reactivity is predominantly determined by the energy content of their molecules and closer similarity of their molecular structures,then the above-mentioned trend may be opposite.The found relationships were used for prediction and verification of the activation energy of non-autocatalyzed thermal decomposition of 2,5-dinitro-2,5-diazahexane. | Marcela Jungová Svatopluk Zeman Adéla Husarová | 2011 | 含能材料2011，19，6： | 5 |
| 7 | Crystal lattice free volume in a study of initiation reactivity of nitramines:Impact sensitivity显示文摘More detailed analysis of a mutual relationship of impact sensitivity(detected by sound) and crystal lattice free volume, △V, for the 18 nitramines shows that its course is not unequivocal. For a part of the studied compounds this sensitivity has increased with increase of the AV values, but for fairly big number of nitramines the relationship works in the opposite direction, especially for data of 1,3,5-trinitro-1,3,5-triazinane, 1,3,5,7-tetranitro-1,3,5,7-tetrazocane. and β-and ε-polymorphs of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane. Initiation reactivity of technical ε-polymorph of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane gives the impression by disorderliness in distribution of the actions of forces in its crystal lattice in comparison with its RS(reduced sensitivity) or chemically pure analogue. Limitations of partial shapes of the mentioned relationship by the molecular-structural similarity, and already published information about the decisive factors governing the crystal structure, signalizes a higher influence of the intermolecular interactions in a crystal lattice in comparison with influence of the crystal lattice free volume for initiation of the crystalline EMs. | Svatopluk Zeman Ning Liu Marcela Jungová Ahmed K.

| 8 | Crystal lattice free volume in a study of initiation reactivity of nitramines:Friction sensitivity显示文摘The relationship between friction sensitivity(FS) and the crystal lattice free space per molecule, △V. of thirteen nitramines is described by a linear equation, divided into a number of the partial relationships with strong limitations by their molecular structure characteristics. Increasing FS due to raising of the △V values is not clearly confirmed. The influence of the △V values on friction sensitivity of nitramines is similar to that of their aza atoms which influence the mutual orientations of nitro groups in neighboring molecules. The dipole-dipole interaction of the oxygen and nitrogen atoms of nitro groups in neighboring nitramine molecules has a major effect on their own FS. In accordance with this interaction, a directly proportional relationship was derived between FS and the intrinsic gas phase molecular volume, V_(int), of the nitramines mentioned, which is divided also into several straight lines according to relatively tight molecular structure similarity. The relationships found again confirm a level of disorder in the distribution of the forces in the crystal lattice of the 'common' quality of ε-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane, in comparison with its reduced sensitivity(RS) or chemically pure analogue. | Svatopluk Zeman Ning Liu Marcela Jungová Ahmed K.Hussein Qi-long Yan | 2018 | Defence Technology(防务技术)2018，14，2： | 5 |
| 9 | Friction Sensitivity of Nitramines. Part Ⅲ:Comparison with Detonation Performance显示文摘The friction sensitivities(FS) of five linear and eight cyclic nitramines have been determined.These FS values were compared with the respective detonation velocities,D,and with the dimensionless ratio created by relating the heat of explosion,Qreal,to the activation energy,Ea,of non-autocatalyzed thermal decomposition of the explosives concerned.For the nitramaines studied,these comparisons show a general trend of FS decreasing with increasing energy content. | Svatopluk Zeman Marcela Jungová Adéla Husarová | 2011 | 含能材料2011，19，6： | 3 |

| 11 | 多硝基芳烃的电火花感度和热安定性关系(英文)显示文摘An ESZ KTTV instrument of a new,relatively simple construction has been applied to determination of electric spark sensitivity of 29 polynitro arenes,expressed as spark energy,EES,required for 50-percent initiation probability.The thermal stability thresholds,Tmax,were calculated from the published Arrhenius parameters of monomolecular thermal decomposition of the studied compounds,predominantly obtained under the conditions of the Russian manometric method.An approximate relationship has been found between the ln EES values and threshold Tmax values.In the sense of this relationship,the compounds studied fall into several sub-groups.The reason of the said diversification lies in the decomposition reaction rate at the temperature of onset of their thermal decomposition.It has been found that in each sub-group increasing thermal stability of polynitro arenes is accompanied by increasing electric spark sensitivity of these substances.This fact must be taken into account if we deal with the problem of electric spark energy transfer into the reaction centre of the molecule. | Svatopluk Zeman | 2008 | 含能材料2008，16，6： | 3 |
| 12 | Impact Sensitivity in Respect of the Crystal Lattice Free Volume and the Characteristics of Plasticity of Some Nitramine Explosives显示文摘The relationship between the crystal lattice free volume,ΔV,and impact sensitivity,E_(dr),of ten nitramines has been analyzed. It was found that this relationship is not uniquely determined,i. e. it is not given only by their own ΔV values but fundamentally by the type and intensity of the intermolecular forces in the nitramine crystals. Also,relationships between the E_(dr)values,on the one hand,and bulk modulus,K,and shear modulus,G,on the other,have been the subject of discussion not only for pure cyclic nitramines but also for their PBXs,bonded by a poly-fluoro binder. The closest linear correlation exists between the E_(dr)values and dimensionless K·G^(-1) ratio which indicates the plasticity range. A similar relationship is valid also for the ΔV values. Relationships of the E_(dr) and / or ΔV values with the shear modulus or to the K·G^(-1) ratio reflect an unusual behavior of ε-HNIW to which the published morphological instability of this particular HNIW version might also be related. | Svatopluk Zeman Marcela JUNGOV Qi-Long YAN | 2015 | 含能材料2015，23，12： | 3 |

| 14 | Crystal lattice free volume and thermal decomposition of nitramines显示文摘The linear, directly proportional, equations between the Arrhenius parameters(E_α, and log A) of the thermal decomposition and the crystal lattice free space per molecule, △V, of 22 nitramines are described. It is shown that, because of a significant limitation by the molecular structural characteristics of such compounds, they are divided into a number of partial relationships. These partial relationships divide the nitramines into a group of substances relating to dimethyl nitramine and a sub-group related to e-HNIW. These directly proportional equations mean that an increase in the △Vvalues is related to an increase in the thermal stability of the corresponding nitramines. A comparison with similar published dependencies for the impact and friction sensitivities, on the one hand, and with the relationship between the E_a values and the sum of the negative and positive extremes of molecular surface electrostatic potentials, on the other, confirms the well-known fact that intermolecular interaction in the nitramines studied plays a decisive role in the thermal reactivity of such compounds. The crystal lattice free space manifests itself here perhaps only in the solid state thermal decomposition of RDX, HMX and DINGU. This study again confirms a level of disorder in the distribution of the forces in the crystal lattice of the'common' quality of e-HNIW,compared with its 'reduced sensitivity(RS)' or pure analogues. | Svatopluk Zeman Ning Liu Ahmed K.Hussein | 2019 | Defence Technology(防务技术)2019，15，1： | 3 |
| 15 | 以环状硝胺为基的几种塑料黏结炸药的初步研究(英文)显示文摘用聚异丁烯(PIB),丙烯腈-聚丁橡胶(ABR),维通A黏结剂和RDX,HMX,BCHMX和ε-HNIW四种硝胺炸药制备了一系列塑性炸药。PETN和以PETN为基的三种塑性炸药用于比较。测试了这些炸药的爆速,撞击和摩擦感度。摩擦感度与撞击感度的关系以及两种感度与D2的关系表明摩擦力向硝胺炸药分子反应中心的转移机理不同于撞击能的转移机理。从摩擦和撞击反应的相互比较以及降低ε-HNIW感度等级中发现撞击感度依赖于硝铵炸药的晶体品质,而摩擦感度的依赖却不明显。测试爆速D与含PIB和ABR黏结剂的PBX装药密度之间的关系表明,ε-HNIW的密度为2.04 g·cm-3时,爆速D为9.800 mm·μs-1。 | Svatopluk Zeman Ahmed Elbeih Zbynek Akstein | 2011 | 含能材料2011，19，1： | 3 |

| 17 | cis-1,3,4,6-Tetranitrooctahydroimidazo-[4,5-d]imidazole(BCHMX)as a part of explosive mixtures显示文摘cis-1,3,4,6-Tetranitrooctahydroimidazo-[4,5-d]imidazole(BCHMX) is a relatively available bicyclic nitramine in the present. Due to the high energetic content of its molecule(deformation of valence angles) it has heat of formation higher than β-1,3,5,7-tetranitro-1,3,5,7-tetrazocane(β-HMX) by nearly three times. As a result, it has heat of explosion and relative explosive strength exceed that of β-HMX including their corresponding PBXs. However, penetration abilities of PBXs based on HMX are higher than those based on BCHMX. The relatively high initiation reactivity of BCHMX could be modified in a wide range by its incorporation in a suitable polymeric matrices. Regarding to the performance, coating of BCHMX crystals by 5 wt% Viton A produces the maximum performance while the mixture of BCHMX with polydimethylsiloxane(PDMS) seems to be the optimum composition for the development of PBX with low sensitivity. | Svatopluk Zeman Ahmed K.Hussein Ahmed Elbeih Marcela Jungova | 2018 | Defence Technology(防务技术)2018，14，5： | 2 |
| 18 | Effect of energy content of the nitraminic plastic bonded explosives on their performance and sensitivity characteristics显示文摘Information about the forty nine nitraminic plastic bonded explosives(PBXs)and different nitramines were collected.Fillers of these PBXs are nitramines 1,3,5-trinitro-1,3,5-triazinane(RDX)and β-1,3,5,7-tetranitro-1,3,5-tetrazocane(β-HMX),cis-1,3,4,6-tetranitro-octahydroimidazo-[4,5-d]imidazole(bicyclo-HMX,BCHMX)and e-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane(e-HNIW,CL-20)which are bonded by polyfluoro-elastomers,polydimethyl-siloxane,poly-glycidyl azide,polyisobutylene,polystyrene-butadiene,poly-acrylonitrile-butadiene and hydroxyl-terminated polybutadiene in addition to a melt cast compositions based on 2,4,6-trinitrotoluene.For thirty two of these PBXs the relationships are specified and analyzed between heats of their combustion and relative explosive strengths;by means of these relationships it might be possible to estimate,which groupings in the macromolecule of binder could be liable to their primary fission in the PBXs initiation.Similarly,for forty two of these explosives,the relationships are described and analyzed between their enthalpies of formation and impact sensitivities;here is especially attention paid to PBXs filled by BCHMX.Specific rate constants from Vacuum Stability Test(VST)of four nitramines and twenty PBXs are introduced into relationships with their enthalpies of formation.Regarding to all the mentioned cases,increasing of energy content of the studied explosives leads to increase of the relative explosive strength or initiation reactivity,respectively.Exception with the opposite trend,the outputs of VST are for BCHMX,where in PBXs are matrices with the esteric plasticizers or the energetic poly-glycidyl azide.Admixture of RDX or HMX,respectively,into the BCHX PBXs gives ternary PBXs whose thermal stability,in the sense of applied VST,is higher comparing to the original binary explosives. | Svatopluk Zeman Ahmed K.
