多排管局部冻结
4) basal melting and refreezing
底部消融与冻结
5) deep frozen clay
冻结深部黏土
1.
The loading and unloading triaxial tests were carried out on the deep frozen clay at four temperature gradients using the method of freezing before K0 consolidation,and attenuation law for deviatoric stress as well as deviatoric stress increasing rates in the process of loading and unloading was investigated.
采用先冻结后K0固结(FC)的传统冻土试验方法进行4种不同温度梯度冻结深部黏土的加、卸荷三轴试验,研究不同温度梯度冻结深部黏土在加、卸荷过程中的偏应力增长速率及偏应力的衰减规律。
6) Piston skirt
活塞裙部
1.
The approximation to the longitudinal-section contour of piston skirt based on BP neural network;
基于BP网络的活塞裙部纵向型线的拟合
2.
As a result of high fuel consumption of 2108 diesel engine,a goal to lower fuel consumption is obtained by improving the design of 108 piston skirt size and optimizing the clearance between the piston and the jacket.
针对2108柴油机机油耗高这一问题,通过改进设计108活塞裙部型线尺寸,优化活塞与缸套的配合间隙,以达到降低柴油机机油消耗率的目的。
3.
For the high-speed and high-performance modern engine,the piston skirt is a very important part in the piston design.
在现代高速、高性能发动机上,活塞裙部是活塞设计中特别重要的部位,裙部形状和表面粗糙度影响着动态油膜的形成与保持,直接影响到发动机机械效率和漏气量。
补充资料:多苯基多亚甲基多异氰酸酯
多苯基多亚甲基多异氰酸酯,简称PAPI,或称粗MDI,浅黄色至褐色粘稠液体.有刺激性气味。相对密度(20℃/20 ℃)1.2,燃点218℃。PAPI实际上是由50%MDI与50%官能度大于2以上的多异氰酸酯组成的混合物。升温时能发生自聚作用。溶于氯苯、邻二氯苯、甲苯等。PAPI的活性低,蒸气压低,只是TDI的百分之一,故毒性很低。
用于制造聚氨脂胶粘剂。也可直接加入橡胶胶粘剂中,改善橡胶与尼龙或聚酯线的粘接性能。贮存于阴凉、通风、干燥的库房内,远离火种、热源。严格防水、防潮,避免光照。
