切下

Five main stalk crops planted in northern China including wheat, corn, broomcorn, soybean, and millet, were chosen to be the samples of the experiments. About seven morphological traits (such as plant height, ear length, ear weight, moisture content and so on) were measured in the crop mature period. The maximum shear force during shearing process, through static test equipment, at the second internode of the basal stalk, was recorded. And shear strength of each crop was calculated to find the differences of shear strength among different crops. The optimal regression models of shear force and morphological traits were obtained by multiple linear regression method with Statistics Analysis System. The equation based on the regression models was constructed.

本文以北方主要茎秆作物（小麦、玉米、高粱、大豆、谷子）为研究对象，试验测定了成熟期茎秆基部第二节间的最大剪切力及株高、穗长、穗重、含水率等七种形态特性指标，获得了静载情况下相关样本的剪切强度；分析比较了不同茎秆作物剪切强度的差异性，并利用SAS软件对茎秆作物剪切力与形态特性指标进行了多元线性回归，得到了剪切强度对形态特性指标的最优回归方程。

The experiment results show that the yield stress increase significantly when nanometer SiO〓 are added, and casson viscosity is lower than the blank sample.

对不同组分的涂料进行了低剪切速率和高剪切速率下的剪切流动，实验说明，比不加入纳米组分的涂料，加入纳米二氧化硅后屈服应力提高，而Casson粘度降低，这说明纳米二氧化硅能够有效地降低涂料的表观粘度。

切利尼是佛罗伦萨人，他出生的年代，正值文艺复兴艺术发展的顶峰，他性格暴躁、但才华出众，切利尼一生有过许多赞助人，在这些著名赞助人的支持下，切利尼制作出了许多优秀的作品，其中包括一些比较大的青铜雕塑，但更多的是小型金属制品，其中最著名的是为法国国王制作的《金盐盒》。

However, CDH has little synergism with cellobiohydrolase or endoglucanase in cellulose degradation. But, if the substrate was pretreated with CDH in the presence of cellobiose, the rate of the hydrolysis of the substrate by cellobiohydrolase or endoglucanase increased.

CDH与纯化的外切纤维素酶或内切纤维素酶或内切纤维素酶之间没有协同作用关系，但在纤维二糖存在条件下底物事先用CDH处理后再用上述纯化的酶水解，作用明显增强。

The first set of tests was that mean stress p was constant while deviator stress q changed; the second set of tests was that q was constant while p changed.

做了2种应力路径下的三轴排水剪切试验：平均应力等于常数、偏应力变化的剪切试验以及偏应力等于常数、平均应力变化的剪切试验。

While a genuine heart is never easy to come by, this unique shape has become one of the most popular cuts. Several years ago Ferri held a Perfect Fancy Cut Diamond Show.

最初一颗钻石晶体不切磨成圆，是因为不适合，如果硬是要切磨成圆形，原石的损耗太多，不符经济原则；於是依其原石情况，在最具效益的情况下，将它们切成各种形状。

The other factor making confinement improve is plasma rotation which is present in almost all current tokamaks It has been shown that the plasma rotation plays an important role in creating or maintaining transport barriers Some researcher have started considering the transport, the instability, and so on in the rotating plasma in the reversed shear configuration.

另外，早先发现等离子体旋转也是改善约束、输运垒形成的重要因素，一些人开始考虑在反磁剪切位形下旋转等离子体中的输运、不稳定性等问题。在本论文中我们把反磁剪切位形下有旋转的托卡马克等离子体理解为高约束先进托卡马克等离子体。

These data show that, in humans and in quadrupeds, the thoracic spine is less rotationally stable under dorsal shear loads than under ventral shear loads.

这些数据显示，对于人和四肢动物，在背侧剪切载荷下比在胸侧剪切载荷下胸椎旋转稳定性更小。

Test results have shown that larger plastic volumetric strain as well as higher growth rate of pore water pressure would be generated in multi-directional shearing than in a single-directional one. Lower resistance of sand to liquefaction was also observed under the rotation of principal stress orientation.

与单向剪切相比，多向剪切会产生额外的塑性体积应变，在不排水条件下孔隙水压力增长的速率较高，特别是在具有主应力轴连续旋转特点的加载条件下，砂土抵抗液化的能力也将更低。

The relationships between strain and stress of several kinds of high strength fibers, such as Kevlar, Twaron and Dyneema were obtained, and the dependence of mechanical properties of fibers on the strain rate was gotten and explained from the microstructures and deformation mechanism of fibers. Then, the damage and failures of plates with the reinforcement of fibers under high velocity impacting were studied experimentally. Based on experimental results, a set of equations was presented to depicted the deceleration of penetrator. The dynamic response of fiber cluster and sandwich were simulated successfully with a new algorithm and code, which was developped by our group. The coupling effect of stress wave and thermal conduction could be considered with acceptable accuracy and CPU time.
