查询词典 elongations

Based on a leveling algorithm, the obliquity angle is converted to elongations of the mechanical supporting to drive the mechanical supporting to level the baseplane. The reasons for choosing three supporting points and mechanical supporting are introduced, then mechanical supportings and the entire transmission system are designed.

给出了支撑腿数量和机械式支腿的选择依据，设计了一种可以在小角度范围内自动矫正受力方向的机械支腿，设计了整个传动系统，并且给出了驱动电路和调平算法。

The fibers are easily broken when the temperature is too low or the drawing velocity is too high, with optimum temperatures and drawing velocities above 60℃ and between 200 and 500mm/min respectively. The drawing of PAN fibers in water is better than in air because it gives larger elongations without fracture.

所以在牵伸过程中，水温不能低于60℃，牵伸速率要适中，在本实验条件下，200mm/min、500mm/min比较合适，而且在水中牵伸比在空气中牵伸效果好，可获得较大的牵伸率。

It is found that the electric, field improves elongations in 2090 and 2090+Ce alloys markedly, especially in 2090 alloy, but has little effect on strengths. At the same time, the electric field lessenes percentages of intergranular delamination and increases transgranular fracture and microscopic plastic deformation.

研究表明：固溶电场可显著提高2090合金及2090+Ce合金的延伸率，尤其是对2090合金，但对强度则无明显的影响；同时，固溶电场减少合金的沿晶分层断裂比例，并增加穿晶断裂及微区塑性变形；固溶电场还使合金时效后δ′相颗粒的平均尺寸减小、尺寸分布范围减小，并使PFZ的宽度减小。

The results showed that CoPI films were amorphous state and their glass-transition temperatures T(subscript g and decomposition temperatures T(subscript d respectively occurred above 322℃ and 544℃. At the same time, the tensile strengths of CoPI films reached beyond 100MPa and breaking elongations were improved from 12% to 54%, but the average of tensile modulus was reduced by 29%. However, polyimide blends had about the same structures and properties with PMDA/ODA-polyimide.

结果表明，CoPI薄膜为非晶态结构，玻璃化转变温度和起始分解温度分别在322℃和544℃以上，断裂伸长率由12%平均提高到54%，拉伸强度均超过100MPa，但弹性模量平均降低了29%；共混PI的聚集态结构和性能与PMDA/ODA型PI相近。

Based on the principle of BP neural network,a neural network model for predicting the properties of SBR compound was established by using the additional levels of several ingredients as the input variables and the corresponding tensile strengthes,elongations at break,tear strengthes and t90 as the output variables.

沈阳化工学院材料科学与工程学院，辽宁沈阳110142）摘要：根据BP神经网络原理，以SBR中的几种配料用量为输入变量，对应的胶料拉伸强度、拉断伸长率、撕裂强度和t90为输出变量，建立神经网络分析预报模型。

The results indicate that the composite adhesives show different effects on the vulcanization characteristics,mechanical properties and dynamic mechanical properties of NR. The cure rates of the compounds with RS/RH, RE/RH and RH are accelerated and the maximum torques,the tensile strengths,hardness as well as tensile stresses at a given elongation are higher than those of the control. Whereas,the elongations at break are lower than those of the control.

结果表明：RS/RH，RE/RH，RH胶料的硫化速度明显较快，最大转矩和其硫化胶的拉伸强度、硬度及定伸应力都显著地高于对照，几种橡胶拉断伸长率均不同程度地小于对照，添加粘合剂的胶料其橡胶与织物附着强度远远大于对照，其中RE/RH胶料最大

Except cellulose acetate fiber,the strength of other four-kind fibers in completely dry state is decreased notably after MHT.With the initial moisture regain increased,the breaking elongations of cotton,rayon and loycell are improved remarkably after MHT.The increasing level is rayon＞loycell＞cotton,but ramie seems little improved.As the moisture regain is low,the fiber initial modulus is enhanced.However,when the moisture regain is higher,the fiber initial modulus did not change obviously.

除了醋酸纤维素纤维，其余四种纤维在初始回潮率为0的时候，经过微波处理，纤维强度都是显著性下降的：随着初始回潮率的增大，棉纤维、粘胶、天丝的断裂伸长率有了显著性的提高，其中升高的幅度为粘胶＞天丝＞棉纤维，苎麻没有显著性提高；在回潮率较小的范围内，微波处理之后纤维的初始模量是增大的，随着回潮率的增大，初始模量变化不显著。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
