Tz = 2Gk q 即 z = 2Gk q /T 40 Suppose the volume between membrane and the boundary plane is V, and we notice that 2 ∫∫ d x d y = M Then we have Thereby we have q qM V =∫∫ zdxdy =∫∫ dxdy = 2GTk 4GTk M 2 Gk = 2V q /T From τ zx =τ xz =, y z 2Gk τ zx /= y q / T τ z y =τ yz = x 41 Moreover, we get 设薄膜及其边界平面之间的体积为V,并注意到 2 ∫∫ d x d y = M 则有从而有由又可得 q qM V =∫∫ zdxdy =∫∫ dxdy = 2GTk 4GTk M 2 Gk = 2V q /T τ zx =τ xz =, y z 2Gk τ zx /= y q / T τ z y =τ yz = x 42 Adjust the pressure q of which the membrane is under, and make the rights of formulas,, equal to one, then we can gain some conclusions as follows:(1) The stress function of wringed pole equals to the uprightness angle of the membrane (2) The torsion M which wringed pole received equals to two times of the volume between the membrane and the boundary plane.

o b y a x 43 调整薄膜所受的压力q，使得，，三式等号的右边为1，则可得出如下结论：(1)扭杆的应力函数等于薄膜的垂度z。(2)扭杆所受的扭矩M等于该薄膜及其边界平面之间的体积的两倍。

The voltage converted into 0～5 V using convering circuit can be used directly by microprocessor ,and con2 verted into digital signals by A/ D converting. So this simplifies the design of the circuits.

通过电压转换电路可以将- 10～+ 10 V 的输出电压转变成为0～5V 的电压，便于带有A/ D 转化电路的单片机系统直接进行A/ D 转换，简化了电路设计。

一次，一名女子是敏感到D -恒河猴抗原，抗-D球蛋白，可以有不具法律效力。

I presented some diagrams of efficiency of a coffee can with different diameters as feeds for parabolas with different F/D and it is very clear how efficiently they work with offset dishes whose F/D is in the range 0.7-0.9.

我提供一些不同直径的咖啡罐做不同F/D的抛物面的馈源的效率图表，可以清楚的看出，当偏馈抛物面天线的F/D在0.7-0.9范围时，它们的工作效率如何。

Cook D-NE20 this work can be said to a higher level than the previous generation models, it can not help but admire SONY exquisite workmanship, ornate paint finish (silver white-blue, red jujube), it can be said, the Big Three evaluation machine, D-NE20 the work is the best, the most attractive.

做上D-NE20这次的做工可以说比上一代机型更上一层楼，实在不能不佩服SONY精致的做工、华丽的烤漆漆面（银白色、宝蓝色、枣红色），可以说，三台评测机中，D-NE20的做工是最好的，也是最吸引人的。

METHODS摘要: A 2 μL of saline or glutamate (375 nmol) was injected into the random unilateral vitreous body for 3 d or 7 d in 18 SD rats.

These studies demonstrate that the more abundant D form interacts with spermatozoa transiently, possibly with a specific receptor on the sperm surface, consistent with a capacitation-suppressing function during sperm transit and storage in the epididymis, and also confirm a tightly bound population of the E form that could act in the female reproductive tract.

研究证明在附睾中运输和储藏期间，大量的D型CRISP-1与精子瞬时的结合与精子的抑制获能功能相关。D型CRISP-1可能与精子表面的受体相结合。同时也证明了E型CRISP-1与精子的紧密地结合模式可能在雌性生殖道中发挥作用
