Similarly, the AMR begin to increase and then decrease with increasing the thickness d of the seed layer, and has a maximum value at a critical thickness d of 5.32nm. Compared to the permalloy films deposited on Ta seed layer ,the AMR enhancement of 10%-46% is observed in the permallay films deposited on (Ni0.82Fe0.18)1-xNbx seed layer.(2) The coercivity Hc1 obtained for magnetic field H applied paralley to the easyaxis is large than Hc2 for H applied perpendicular to the in-plane easy axis, and both of coercivity are consistent with the change of x.

2沿样品易轴方向的矫顽力Hc_1比难轴方向的矫顽力Hc_2大，两者随Nb原子的百分含量x的变化是一致的，饱和磁化强度Ms随x的增大先增大后减小，在x=27.1％处，Hc_1和Hc_2都比较小，而Ms则达到最大；种子层厚度d不能明显改变坡莫合金薄膜的磁性能；与以传统材料Ta为种子层的坡莫合金薄膜相比，以Ni_(0.82Fe_(0.18)_(0.829)Nb_(0.271)为种子层的坡莫合金薄膜的矫顽力只有轻微减小，但是Msg 以w讪Fq.t）lkNk为种于层的坡莫合全薄膜的各向异性戳电阻及磁性能研究却要大，mk坡莫合金层厂度！

University of Michigan pharmacologist Robert U. Simpson, Ph.D., thinks it's apt to call vitamin D the heart tranquilizer.

"美国密西根大学药理罗伯特美国辛普森，博士，认为它的APT呼吁维生素D的"心脏镇定剂。

Based on the description of Mohr-Coulomb and Drucker-Prager yield criteria with invariant of stress, a formula for error estimation of unit strain energy between the two stress states is established in the deviatoric plane of the principal stress space, which satisfies M-C and D-P yield criteria respectively. A general procedure to transform M-C material parameters to D-P analysis parameters is obtained.

基于应变比能的概念，在偏平面内建立了分别进入Mohr-Coulomb和Drucker-Prager屈服面时所需形状改变比能的差值公式，获得M-C材料参数向D-P计算参数等效的统一性方案。

D . The film never uses 3-D simply because it has it, and doesn't promiscuously violate the fourth wall.

D-lactic acid is considered to be a very important chemical compound as a chiral material or intermediate in organic synthesis. D-LA is a prosoma of many chiral compounds with applications not only in the pharmaceutical and cosmetic industry but also in highly efficient and lowly toxic pesticide and herbicide.

D-乳酸是重要的手性中间体与有机合成原料，是多种手性物质的前体，广泛应用于制药、化妆品和高效低毒农药及除草剂等领域的手性合成。

One day, while I was playing with my new doll, Miss Sullivan put by big rag doll imo my lap also, spelled "d-o-l-l" and tried to make me understand that "d-o-l-l" applied to both.

一天，我正在和我新得的娃娃玩，沙利文小姐把另一只大点儿的布做的娃娃也摆在我的膝盖上，并拼出了d-o-l-l这个词，试图让我明白这个词两只娃娃都适用。

Further study suggested that the D-serine produced in astrocytes regulates the function of NMDA receptor through the glycine-binding site of the receptor.

这种内源性D-Ser在神经系统中的分布与NMDA受体的分布相平行，进一步的研究表明，D-Ser由突触旁星形胶质细胞产生，而作用于突触后NMDA受体上的Gly结合位点，对NMDA受体的功能进行调控。

Result: The ROM of group A had no significant difference with that of the control group. The ROM of group B had no significant difference with that of the control group except rotation, each ROM of group C and group D was significant difference with the control group, and the ROM of group D was the biggest. The ROM of group E was the smallest and had statistically significant difference in each motion compared with the control.

结果：A组ROM值与对照组无显著性差异；B组除旋转外与对照组无显著性差异，旋转稳定性也达到了对照组的61.86%；C组与对照组均有显著性差异；D组ROM值最大，与对照组有显著性差异；E组除后伸外ROM值均明显小于对照组，差异有显著性(P.05)。
