cast nylon造句

• For the heat conduct coefficient of casting nylon is much lower than metal , when making shaft lines , the wall should be as thin as possible
  由于铸型尼的导热系数比金属小的多，所以做轴套时，壁厚应尽量薄一些。
• The heat expansion coefficient of casting nylon materials is about 10 times larger than steel , so the internal dia shrinks caused by the expansion . it will influence the connection gap of the abrasive surface
  铸型尼材料的热膨胀系数约比钢材大10倍左右，所以轴套在运行时由于摩擦热所造成的膨胀变形使内径缩小，影响摩擦面的配合间隙。
• The polymerization kinetics of pam , the feeding pattern of the initiator naoh and a method used to characterize the spherulite morphology of monomer casting nylon were investigated . the mechanics of inhibition of pam to the polymerization of nylon was certificated by means of a series of experiments
  通过两个体系的pam pa - 6复合材料的力学性能、 sem 、 xrd 、 dsc和tem等测试方法研究复合材料的结构与性能间关系，表明聚甲亚胺端基对复合材料性能有一定的影响。
