The v was tested by yjy stress transducer with mvad card by the methods of recording the deformation in the wideness and thickness direction of the specimens during the tensile test . a stable auxetic polyolefin blend with the minimal value - 1 . 4 was observed after repeated test 采用附有mvad通道卡的yjy型片式传感器,记录试样在拉伸过程中宽度和厚度方向的形变并根据泊松比的定义进行计算,反复实验后获得最小值为- 1 . 4的负泊松比烯烃共混体系。
The genesis of the zongpu is traceable to the zhou dynasty 1050 - 221 bc while other countries have their own methods of recording their heritage to suit their own requirements , the chinese have developed theirs into a fine art , with characteristics and flavours that would be difficult to duplicate 宗谱的诞生可以追溯到周朝公元前1050 221 。其他国家按照自己的需求,用自己的方式记录过去。中国人更将其发扬光大,记录族谱成了一门艺术,难以复制。
