查询词典 couping

Based on the hypothesis of Cole-Cole model, a new recursive inversion method is used in the inversion of complex-resistivity sounding curves over multi-layered earth with Schlumberger array without electromagnetic couping.

在Cole Cole模型假设的基础上，用一种新的递推反演算法对无电磁偶合影响时的水平层状大地对称四极装置复电阻率测深曲线进行反演，得出了层状大地上视电阻率、视时间常数、视频率相关系数、视充电率的视真频参数测深曲线。

Privilege view sub-model not only raises performance of privilege session but also forms a data abstract layer, so, other systems only access privilege system through privilege view without understanding details of privilege system.MISBAC has an important feature that it is the low couping in sub-models, so they are easy to restructure, and if privilege view sub-model is not changed, MISBAC can be restructure without destroying other modules of MIS.

权限视图子模型不但提升了权限会话的性能，更为重要的是它在权限管理系统中提供了一个数据抽象层，使得其他系统对权限系统的访问只需要通过权限视图，而不必深入到权限系统内部。

Then we completed the first total synthesis of-Plakoridine A using Eschenmoser couping reaction as akey step. During the synthesis we found the choice of protecting groups and the configuration of the chiralcenter of the substrate play an important role to the key Eschenmoser reaction,so we think our successwould be of guide for synthesizing other polysubstituted pyrrolidines or piperidines.

在论文的第一章中，我们先以易得的对羟基苯乙酸乙酯为原料经多步反应制得了所需的β氨基酸酯，然后利用立体选择性的Aldol缩合反应和内酰胺化反应制得了Plakoridine Alactam，随后，以Eshenmoser缩合反应为关键步骤完成了生物碱-Plakoridine A的首次不对称全合成。

The phonon spontaneous emission causes the decoherence of the qubit. We discussed the relatoion between the decoherence time and the Coulomb binding parameter,the couping strength, the confinement length, and the conefficient dispersion.

由于声子的自发辐射，造成量子比特的消相干，讨论了消相干时间与库仑结合参数，耦合强度，受限长度，色散系数的变化关系。

A new monomer,4-hexanoxyl-4′-undecylene-[10]-acyloxyazobenzene was synthesized using the main materials:phenol,underlenic acid,1-bromo- n -hexane, p -nitrophenol,thionyl chloride,by the substitution,reduction,couping and diazotization methods.A new polymer was prepared by hydrosilation reaction of poly (methylhy-drosiloxane) with the monomer.

以苯酚、十一烯酸、正溴己烷、对硝基苯酚和二氯亚砜为主要原料，通过取代、还原、重氮化和偶合等反应，合成了一种新的液晶单体 4-己氧基-4′-十一烯-[10]-酰氧基偶氮苯，并与聚通过硅氢加成生成一种新的高分子液晶。

Basing on this mode and his two invention patents, chooseing ANSYS as platform and linking the important project of JiLin province Science and technology ministry 'cylindrical and cone spurgears rolling preform and extrusion precise forming equipment research and manufacture for automobile'(NO.20030311), the author made the finite element numerical simulation about elasto-plastic large deformation heat-force couping of rolling preform and stamping-extrusion and bulge-extrusion combining precise forming for spur gear', investigated qualitativiely and quantitatively on the gears formability for the environmental and the blank parameters , summarized some useful conclusions.
