查询词典 R.R.

The structure of polarimeter is different from the traditional polarimeter. Changing the ratio of R/a between the radius of the metal stick and the lattice constant can design the working wave band in advance and obtain high degree of polarization and transmission rate.

本发明提供的偏振器结构不同于传统的偏振器，它可以通过只改变金属棒的半径和晶格常数R/a的比，预先设计工作波段，并且可以得到高的偏振度和透射率。

The law of refraction, discovered first empirically by Willebrord SNELL, then subsequently derived formally by Descartes and Fermat, states that sin r = K sin i, where i is called the angle of incidence, the angle between the incident ray and the normal to the refracting surface.

折射的轨律，首先被 Willebrord SNELL 靠经验发现，接着后来正式被笛卡尔和 Fermat 认定，规定 sin r = K sin i ，这里 i 被称作入射角，入射光线和法线到折射平面之间的夹角。

The molecular charge distribution of the reactivator is affect the reactivating efficacy directly. Moreover its association with hydroximic acid dissociation constant pAa closely, and it will have a great impact on reactivating ability indirectly.(3) There is likely to exist front molecular interaction between Cholinesterase Reactivators and OPC-inhibited AChE, the action sites mainly lie on the aromatic ring, the substitute R and the hydroixic acid group. They act on the aromatic residues of AChE by Π-Π conjugation .(4) The reached results by Comparative Molecular Field Analysis is useful to design new higher efficacy derivatives for 1, 2, 4-oxadiazole class nonquaternary Cholinesterase Reactivators.

2复能剂分子的电荷分布直接影响复活活性，同时对肟酸解离常数pKa具有重要影响，间接影响复活能力；(3)复能剂与磷酰化酶可能存在前线轨道作用，作用部位可能主要在芳香环及其取代基R和肟基上，与AchE的芳香族残基发生л-л电子作用；(4)通过比较分子力场法研究可以指导1，2，4-oxadiazole类非季铵肟胆碱酯酶重活化剂新化合物的合成，可能得到活性更高的复能剂。

R and S type LTSs are proposed.It is proved that the optimal distributed CFAR detection based on the above two LTSs in NP sense is in form of likelihood ratio test.

提出了R类和S类局部检测统计量，证明了基于这两种局部检测统计量的在NP意义上的最优分布式CFAR检测具有似然比检验形式。
