阿铜铬双金属板具有2μ铬层表面涂有在一轻甲苯百分之四解决敏感的聚合物含有光敏感芳sulphonylazide团体和一个连接到聚合物骨架羟基小数额。

The result indicated that suitable thickness of paddy soil is about 15cm,and for dry arable land it should not be lower than 20cm;The alluvial rivers parent material is the best one to influent the output,the rice fields is the worst with the parent material of slate ground,while the dry and plough land is the worst for its purple sand shale parent material;The paddy rice is best with the acid soil,and the dry crop is the best with the neutral soil;The obstacles horizon exist in 35.2%of the rice fields in research region,and many for middle or top digit obstacles.

结果表明，水稻土的适宜耕层厚度为15 cm左右，旱耕地适宜耕层厚度应不低于20cm；成土母质对产量的影响以河湖沉积物母质最好，稻田以板页岩母质最差，旱耕地以紫色砂页岩母质最差；水稻以酸性土最好，旱作以中性土最好；研究区稻田有35.2%的存在障碍层，且多为中、高位障碍，是影响水稻产量整体提高的主要因素；水稻和旱作都以壤土为最好，其中，稻作怕砂，旱作怕粘；水稻土适宜的容重为1.00—1.29 g/cm~3。

The basic topcoat material can be embossed and can be applied in combination with other protective topcoats and laminates.

基本面漆材料可压纹，可用于与其他保护性的面漆涂层和层压板相组合。

A transcendental equation is used to determine the vibration frequency with given materials and plate thicknesses.

通过给定层状薄膜板的材料常数和厚度，我们可以从频率方程中求解出其振动频率。

By a series of bending cyclic tests of wood-bamboo laminate under 80%, 75%, and 70% stress levels, transformation laws' curves of the damage variable were measured at three different maximum stresses.

通过对竹木复合层合板在80%、75%和70% 3种应力水平下的纯疲劳弯曲试验，得出其损伤变量变化规律的实验曲线。

The flexural strength retaintions of the laminates based on resins of binary system are above 80% at 200℃, and that of trinary system are above 70%.

最后，本文还以二元共聚树脂和三元共聚树脂为基体选择制备了三类共11个配方的玻璃布层压板。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
