| 1 | Time-dependent viscoelastic behavior of an LDPE melt显示文摘二个微分组成的方程,即 Giesekus 模型和 Johnson Segalman 模型这里被雇用预言时间依赖者 LDPE 的粘弹性的行为融化在 thixotropy 环实验和步砍率实验。多重松驰模式被采用,并且过去常在二个模型描述非线性的粘弹性的参数被适合砍变瘦粘性获得。那些上的预言短暂砍由二个模型的特征在对我们的以前的实验的质的同意被发现。Johnson Segalman 模型在 thixotropy 环和步预言摆动行为砍评估实验,而 Giesekus 模型不做。两个模型更高预言砍在砍的长时间的情况中比试验性的数据强调,暗示两个模型不能完全描绘时间依赖者砍 melt 在的应力高砍率。 | Shuxin Huang Chuanjing Lu Yurun Fan | 2006 | Acta Mechanica Sinica2006，22，3： | 1 |
| 2 | A new semi-empirical spectrum model for complex steady shear viscosity of complex fluids显示文摘A semi-empirical spectrum model is proposed todescribe the experimental data of the steady shear propertiesof a Shengli waxy crude oil near its gel point, where sophisticatedstructural effects become apparent due to the existenceof waxy crystals in the crude oil. The model, consisting of atime spectrum, can well fit the steady shear viscosities of thewaxy crude oil over the whole experimental shear rate regionfrom 10^-4 to 10~2 s^-1.Two other experiments on complex fluidsreported recently in the literature are also well describedby this model demonstrating the applicability and accuracyof the model. | Shuxin Huang Chuanjing Lu Yurun Fan | 2009 | Acta Mechanica Sinica2009，25，6： | 0 |
| 3 | Toughening of vinyl ester resins by two-dimensional MXene nanosheets显示文摘Two-dimensional nanosheets are highly effective tougheners for vinyl ester resins.The toughening effect is related to the high specific surface area and unique two-dimensional planar structure of the nanosheets.In this study,a coupling agentγ-(2,3-epoxypropoxy)propytrimethoxysilane(Kh-560)was used to modify MXene nanosheets(M-MXene)for use in toughening vinyl ester resin.The mechanical properties,including the tensile strength,flexural strength,Young’s modulus and elongation,of neat vinyl ester resin and vinyl ester resin modified with MXene and M-MXene were investigated.The results showed that modification significantly improved the mechanical properties of the vinyl ester resin.The tensile and flexural strengths of the MXene-nanosheet-modified vinyl ester resin were 27.20%and 25.32%higher,respectively,than those of the neat vinyl ester resin.The coupling agent improved the interfacial compatibility between the MXene nanosheets and vinyl ester resin,which resulted in the tensile and flexural strengths of the M-MXene-nanosheet-modified vinyl ester resin being 52.57%and 54.60%higher,respectively,than those of the neat vinyl ester resin for a loading quantity of nanosheets of only 0.04 wt%,which is economically viable.The main mechanisms by which the nanosheets toughen the resin are crack deflection and crack pinning. | Yurun Dai Heng Fang Zong Lu Zhuohong Yang Yanying Wei | 2022 | Frontiers of Chemical Science and Engineering2022，16，11： | 0 |
| 4 | Application of geophysical-geochemical method in verification of stream sediment anomaly in Baoxinggou area of Heilongjiang显示文摘Baoxinggou area is located in northern Daxing'anling. In this area,comprehensive use of geophysical and geochemical exploration methods plays an important role in the prospecting,and has yielded some application results so far. Based on the 1 /100 000 stream sediment anomaly survey,the methods of 1 /20 000 soil geochemical measurement,trenching engineering on the earth's surface and 1 /10 000 IP intermediate gradient survey were all used to verify and decompose drainage anomalies,as well as to find and locate ore bodies. In this way,an effective,economical and quick prospecting method was concluded,which focuses on the middle and lower mountain forest swamp landscape in the northern part of Daxing'anling,and provides reference for the prospecting in the area. | LU Yurun LIU Cai LI Qinglu YU Chengwei ZHANG Donghui | 2015 | Global Geology2015，18，1： | 0 |
| 5 | Four-junction AlGaAs/GaAs laser power converter显示文摘Four-junction AlGaAs/GaAs laser power converters (LPCs) with n^+-Ga As/p^+-Al_(0.37)Ga_(0.63)As hetero-structure tunnel junctions (TJs) have been designed and grown by metal-organic chemical vapor deposition(MOCVD) for converting the power of 808 nm lasers. A maximum conversion efficiency ηc of 56.9% ± 4% is obtained for cells with an aperture of 3.14 mm^2 at an input laser power of 0.2 W, while dropping to 43.3% at 1.5 W.Measured current–voltage (I–V) characteristics indicate that the performance of the LPC can be further improved by increasing the tunneling current density of TJs and optimizing the thicknesses of sub-cells to achieve current matching in LPC. | Jie Huang Yurun Sun Yongming Zhao Shuzhen Yu Jianrong Dong Jiping Xue Chi Xue Jin Wang Yunqing Lu Yanwen Ding | 2018 | Journal of Semiconductors2018，39，4： | 0 |
