| 1 | 应用生物标志化合物参数判识古沉积环境显示文摘本文应用分子有机地球化学方法研究了中国陆相沉积盆地22个代表性样品,试图确认陆相沉积物的古环境。样品包括白垩纪至第三纪的油页岩、页岩、泥岩和芒硝。根据地质和地球化学资料判断,所研究的样品均为湖相沉积物。按盐度可划分为淡水、半咸水或淡水和高盐度水或咸水三种环境的沉积物。对沉积样品抽提物的脂肪烃组分进行了色谱分析和色谱-质谱分析,并在质量色谱图上测得无环烷烃和环烷烃化合物的相对丰度及有关参数。 | 傅家谟 盛国英 许家友 贾蓉芬 范善发 彭平安 Eglinton G.Gowar A.P. | 1991 | 地球化学1991，20，1： | 126 |
| 2 | 胜利油田原油和生油岩中的生物标志化合物及其应用显示文摘Aliphatic hydrocarbons and aromatic steranes of 11 oil and 6 shale samples from the Zhanhua Depression have been examined by GC-MS with particular attention paid to the so-called biological markers i.e., steranes, triterpanes, and aromatic steranes. No correlation has been established between oil maturity and reservoir depth, suggesting that the present maturity of oil is related mainly to maturation effects in the source rocks rather than in the reservoir. Oil samples pooled from depth of ca. < 1300m in Gudoan, Chenzhikoun uplift show signs of extensive biodegradation (n-alkanes all removed) whilst those pooled from depth > 1500 m are unaffected. The shales show progressive increase in the extent of aromatization of aromatic steranes and the extent of configurational isomerization in the hopanes which correlate well with present burial depth. A number of ratios and compound distributions thought to be indicative of either maturity of palcoenviromnent suggest the upper Shahejie represented by Y121 as the most likely source for the Y118 oil which is less mature than all other oils. The main source (s) for all other oils is more mature (by sterane isomerisation) than all shales examined. This increase in maturity indicates that their source was either a)Shahejie shales elsewhere in the depression with lower average heating rate but similar maximum temperature to the deeper samples examined; or b) sediments older than the Shahejie. | 史继扬 A.S.麦坎任 G.埃格林顿 A.P.戈瓦 J.R.马克斯威尔 | 1982 | 地球化学1982，11，1： | 23 |
| 3 | 铁粉基软磁复合材料绝缘包覆层的研究显示文摘利用化学处理法在铁磁粉表面直接生成无机磷酸盐包覆层,并采用粉末冶金法进行压制烧结得到铁粉基软磁复合材料(SMCs)。利用扫描电子显微镜和X射线衍射对SMC材料包覆层的显微形貌和组成进行了分析,并利用差热热重分析法探讨了包裹层的高温变化。结果表明,化学处理法能够实现铁粉表面的磷酸盐包覆,且在600℃左右非晶态磷酸铁会发生晶化作用,从而可能转变成可导体使包裹层的绝缘性被破坏,而非其高温热分解造成,这还需要进一步的电阻测量试验来证实。 | 刘菲菲 BAKER A.P. 翁履谦 宋申华 | 2007 | 材料开发与应用2007，22，5： | 19 |
| 4 | 把历史引进物理教学的乐趣和危险显示文摘1983年在意大利帕维亚召开的“用物理学史革新物理教育”国际讨论会是近年来国际上为讨论物理教育革新问题而举行的一系列会议之一.本文是该会上的一篇发言.本文作者弗伦奇教授曾任国际物理教育委员会(ICPE)主席,是国际知名的物理学教育家.他的这篇发言深刻而风趣,在很大程度上反映了当前国际物理教育界关心的主要问题.故将此文推荐给我国的物理老师. | A.P.弗伦奇 陈秉乾 王稼军 | 1986 | 大学物理1986，0，2： | 18 |
| 5 | 基于应变分布响应的模态分析理论与应用显示文摘模态分析技术经过近70年的发展已形成较为完整的独特理论和方法,这与模态测试手段的进步息息相关。由于传感技术的限制,既有的模态分析方法主要是基于加速度或速度测量开展的,重点关注位移、速度及加速度频响函数。过去5年间,本课题组研究和开发了用于重大工程结构的分布式应变传感技术,并以分布式动态应变测量为核心开展了包括模态分析理论、模态测试及工程应用在内的研究工作。本文简要介绍分布式动态应变传感技术的基本特点和系统构成,重点阐述基于应变分布响应的模态分析理论、应变频响函数的测试技术及相应的模态参数识别方法。应变模态分析表明,从时频域上看,应变频响是更类似于位移频响而不同于速度或加速度频响的物理量,因此对低频响应更为敏感;基于位移频响函数和基于应变频响函数提取结构固有频率和阻尼比等价有效;基于位移频响函数和基于应变频响函数提取的特征向量之间的相互关系与位移和应变测量之间的映射关系完全相同,即基于应变频响获得的特征向量是直接的应变模态测量。探讨了应变模态在大柔度结构低频测试、动力模型重构、结构损伤识别3方面工程应用中的优势。 | 吴智深 李素贞 ADEWUYI A.P. | 2010 | 科技导报2010，28，8： | 13 |
| 6 | 赞比亚卢弗里安弧构造带再活化的证据:锆石和磷灰石裂变径迹年代学显示文摘锆石和磷灰石裂变径迹年代学对揭示构造热事件的形成及演化过程具有重要的研究意义.利用锆石和磷灰石裂变径迹测试及热史模拟探讨了卢弗里安弧构造带自泛非构造运动以来的构造热演化过程.谦比希铜矿床和恩昌加铜(钴)矿床位于卢弗里安弧铜-钴成矿带中的赞比亚境内.对采自该两个矿床中的5件新鲜岩石样品进行挑选,获得了5件锆石和4件磷灰石样品.首次获得了卢弗里安弧构造带中的裂变径迹年龄,5件锆石样品的年龄分别为265±22Ma、230±10Ma、228±9Ma、225±9Ma和221±10Ma.4件磷灰石样品的年龄分别为145±10Ma、133±10Ma、130±10Ma和92±9Ma,径迹长度介于(11.4±2.4)^(11.8±2.4)μm.从热历史模拟结果可看出,从300~260Ma,古地温持续降低至90℃左右;随后,缓慢降低至现今的地表温度.对比卢弗里安弧构造带、赞比西构造带和达马拉构造带中的年龄数据,研究表明非洲中南部地区二叠纪-白垩纪的构造活动是一个区域性的构造活动事件. | 任军平 王杰 张东红 Dokowe,A.P.

| 8 | In situ strength of coal bed based on the size effect study on the uniaxial compressive strength显示文摘In the early 1990 s, the Foundation for Science and Technology of Rio Grande do Sul State(CIENTEC)developed a pioneering study in Brazil, related to the simultaneous mining of multiple coal seams.One of the activities included detailed studies on the geomechanical characterization of materials present in the Irapua coal seam, under exploitation in the A-Sangao Mine, located near the city of Criciuma-SC,within the South-Catarinense coalfield. The goal of the laboratory tests was to define the behavior of the uniaxial compressive strength of the Irapua coal seam and establish a first approximation for the in situ strength value of this coal seam, since existing knowledge is solely based on practical mining experience over the years. Large samples of the coal seam were collected, using special techniques to maintain the integrity of the material, and a set of 56 uniaxial compression tests in cubic specimens, with side length ranging from 4.5 to 31 cm, were conducted in laboratory. This paper describes the experimental techniques used in the assays, and also presents the uniaxial compression strength results obtained.Moreover, important aspects of this type of study are considered, highlighting the size effect for the carbonaceous bed and the estimation of in situ strength values for the Irapua coal seam. | Gonzatti C.

| 9 | Interfacial bonding mechanism in Al/coated steel dissimilar refill friction stir spot welds显示文摘Defect-free dissimilar Al/zinc coated steel and Al/AlSi coated steel welds were successfully fabricated by refill friction stir spot welding. However, Al alloy and uncoated steel could not be welded under the same welding condition. Al-Zn eutectic layer formed at the Al/zinc coated steel interface showed nonuniformity in thickness and nanoscale intermetallic(IMC) produced was discontinuous. The bonding formation between the Al-Zn layer and the surrounding materials was attributed to a liquid/solid reaction mechanism. Bonding formation at Al alloy and AlSi coated steel interface was attributed to a solid/solid reaction mechanism, as the joining process did not involve with melting of base metals or AlSi coating materials. Kissing bond formed at the weld boundary acted as a crack initiation and propagation site,and the present study showed that weld strength of Al 5754/AlSi coated steel was greatly influenced by properties of original IMC layer. | Z.

| 10 | 热力学抑制剂与CO_2同注开采天然气水合物的实验研究显示文摘为解决CO_2置换法开采天然气水合物(以下简称水合物)过程中出现的置换速率慢、置换程度不高等问题,提出了将CO_2置换法与热力学抑制剂法组合使用的技术思路,即'抑制剂—置换法'。在实验室利用填砂管模型在岩心驱替装置上测定了CO_2与不同浓度的甲醇溶液在同注的情况下CH_4水合物的分解效果。结果表明:(1)甲醇的浓度对水合物开采效果起着决定性作用,甲醇溶液浓度越小,CH_4水合物的分解越弱,其变化趋势表现为以CH_4水合物的分解为主导转变为以CO_2水合物的生成为主导;(2)当CO_2与浓度为20.8%的甲醇溶液同注时,主要发生CH_4水合物的分解,CO_2水合物几乎不生成;(3)当CO_2与浓度为15%的甲醇溶液同注时,既发生CH_4水合物的分解,也发生CO_2水合物的生成;(4)当CO_2与浓度为10%的甲醇溶液同注时,CH_4水合物几乎不分解,主要发生CO_2水合物的生成。结论认为,'抑制剂—置换法'可促进CH_4水合物的分解,提高其开采效率。 | Khlebnikov V.N.

| 13 | 食管静脉曲张治疗:内镜下硬化和EUS引导下硬化治疗食管侧支静脉的随机对照研究显示文摘Background: Endoscopic sclerotherapy (ES) and band ligation are standard treatments for esophageal varices. Unfortunately, recurrence is common and seems to be related to esophageal collateral vessels, easily identified by EUS. Eradication of these vessels might lead to a more durable therapeutic effect. Objective: To compare ES with EUS-guided sclerotherapy of collateral vessels (EUS-ES). Design: Randomized controlled trial. Setting: Endoscopy Unit, Division of Gastroenterology. Universidade Federal de S o Paulo, S o Paulo, Brazil. Patients and Interventions: Fifty cirrhotic patientswith esophageal varices were randomized into 2 groups: ES (n = 25) and EUS-ES (n = 25). EUS-ES was targeted at collateral veins. Patients were followed-up for at least 6 months after eradication. Main Outcome Measurements: Efficacy in eradication, complications, and recurrence of varices. Results: Varices were eradicated in 48 patients who adhered to the study protocol. The mean (SD) number of sessions until eradication was 4.3 (1.5) for the ES group and 4.1 (1.2) for the EUS-ES group. In ES group, 4 patients had mild bleeding. In EUS-ES group, 4 patients had pain. The mean (SD) length of the follow-up period was 22.6 (6.9) months for the ES group and 24.9 (8.1) months for the EUS-ES group. Recurrence was seen in 4 patients after ES and in 2 after EUS-ES (P = .32). The presence of collateral vessels was associated with recurrence (P = .003). Conclusion: EUS-ES is as safe and effective as ES in variceal eradication. Recurrence tends to be less frequent and occurs later. Persistence of esophageal collateral vessels after sclerotherapy is a risk factor for recurrence. | Andrade De Paulo G. Ardengh J. C. Nakao F. S.

| 14 | 语言哲学显示文摘本文试图解释一些20世纪英-美哲学家支持的重要主题和理论问题。哲学自身是研究实在的基本成分或人类所拥有的基本概念。因此语言哲学是研究语言理解的最基本概念。最明显的概念是意义、意谓事物的词和句子。然而理解什么是意义并不容易。意义的研究导致了语言哲学的其他概念——句法、语义和语用的产生,这些概念是语义哲学的中心概念。 | A.P.马蒂尼奇 周建设(译) | 2009 | 首都师范大学学报(社会科学版)2009，，6： | 3 |
| 15 | “比较音乐学”和“音乐民族学”的界定——一种历史的、理论的透视显示文摘《音乐民族学》刊物和其它刊物的读者们,对于我过去数年在界定什么是音乐民族学,以及音乐民族学应该是什么的持久兴趣(例如,梅里亚姆,1960、1969.1975)是不会陌生的。根据共同的信条,J·孔斯特(Jaap Kunst)首次将“民族——音乐学”(Ethno-Musicology)放入他的著作(1950)至今已25年之久了。因此,我们现在对这一词已发生了什么以及与它的前身“比较音乐学”相比发生了什么作一些客观的回顾。换言之,尽管离最终结论的判定还相距很远,而这些观点已成为史实。本着这种历史的精神,我希望在这些材料内部作些讨论。虽然,在试图发现所有关于音乐民族学的界定中我不曾细密搜查翻遍所有的文献,但我收集了它们主要的一些界定,我相信,这些在很大程度上足以表明它们所具有的倾向和变化,虽然我并没有到过美国以外的大部分地区,而且包括一些在它们那里看起来特别适宜的定义。我在此的主要目的,是讨论在美国这两个术语过去发生了什么变化,由于这些变化的发生出现了什么结果。 | A.P.梅里亚姆 管建华 | 1992 | 交响(西安音乐学院学报)1992，11，1： | 3 |
| 16 | 甲醇与CO_2/CH_4混合气开采天然气水合物研究显示文摘针对CO_2置换法开采CH_4水合物的过程中CO_2水合物在井底过早生成、高压下CO_2发生液化导致渗流过程驱替阻力过大等问题,同时为了获得高压且富含CH_4的产物气,选择CO_2/CH_4混合物作注入气,在岩芯驱替装置上研究了'抑制剂-气体置换法'分解CH_4水合物的过程。结果表明,当混合气中CH_4体积分数为57.4%时,可在7.5 MPa下获得体积分数为72.9%的CH_4产物气,并且获得的CH_4产物气的量要显著大于所注入的CH_4的量。另外,还评估了在地层深部低体积分数的甲醇溶液(20%)和高体积分数CH_4混合气(77.9%)对天然气水合物的分解效果,结果显示,随着'抑制剂-气体置换法'分解天然气水合物过程的进行,地层深部的CH_4水合物基本不发生分解,但CO_2水合物生成过程依然十分显著。 | 梁萌 Gushchin P.A.

| 18 | DEVELOPMENT AND APPLICATION OF ADAPTIVE MESH TECHNIQUE IN THREE DIMENSIONAL NUMERICAL SIMULATION OF WELDING PROCESS显示文摘The adaptive mesh mesh technique is developed and applied in three dimensional numerical simulation of welding process on the base of the commercial software. Special user subroutine is worked out to accom- plish this function.This technique can make the dense mesh moving simultaneously with the heat source while the other area of the structure with much coarser mesh, greatly reducing the number of nodes and elements in the analysis.Temperature field,displacement and stress distributions during welding pro- cess me analyzed by FEM method with adaptive mesh and the analysis is also conducted with normal FEM method. The temperature field,displacement and stress distributions obtained with both methods are shown in contrast. The results show that the temperature fields and the displacement distributions of simulation on adaptive mesh correspond wery well with that of without adaptive mesh. Though the stress distributions have some difference,but the trends of the stress distribution are corresponding.The com- parison of the computing time of the two meshes indicates that the adaptive that the adaptive mesh can greatly reduce the calculation time when used for welding process. | Q.
