The calculations show that the approximation for the birefringence and the rotatory property of interaction material leads to an error in the optimum incident angle for TeO2 more than 10%, a diviation in fa-λ0 relation from experiment results, and make the spectral resolution and angular aperture of the device to be degrade.

结果指出，在该波长下，对晶体双折射取近似表达式和不计入晶体的旋光特性，对光波最佳入射角θi的选取(在θi小于60°的范围内)，将引入大于10%的误差，这个误差由于涉及到是否满足动量匹配条件，因此会对器件的性能有直接的影响。

Correlation between spin angular momentum s and background angular momentums of planets;2. In the paper the principle of optical rotation due to the transfer of spin angular momentum from light to particles was discussed by analyzing the interaction between the beam of light and birefringent crystal particles, and then an optical tweezers was formed on nanometer optical tweezers system with a linearly polarized light beam (He-Ne laser 633 nm, 10 mW).

从理论上分析了偏振光束与双折射晶体粒子的相互作用过程，讨论了由于光束自旋角动量向晶体粒子的传递所导致的光致旋转效应的原理，并在纳米光镊装置上利用线偏振He Ne激光器(633 nm，10 mW)形成了光镊光阱，利用1/4波片来改变光镊光束的偏振状态，在不同的椭圆偏振状态下实现了直径约为几微米的CaCO3 晶体微粒的捕获和光致转动。

Quantitative structure-activity relationship studies showed that when the test grass was rape, their herbicidal activity was mainly related with substituent molar refractivity; when the test grass was barnyard grass, their herbicidal activity was mainly related with the electronic parameters of the substituents at the para-position of benzene ring.

定量的结构与活性关系研究表明，当作用对象为油菜时，化合物的活性可能主要与取代基R的摩尔分子折射常数有关；当作用对象为稗草时，化合物的活性可能主要与取代基R的电性参数有关。1-位为氢时，有利于对油菜生长的抑制；1-位为甲基时，有利于对稗草生长的抑制。

Slangs can not only reflect the character and inward world of coiner and user aslo can refract society and culture phenomena that can express sense of worth , ethics, thinking manner of human. American have relative strong personality that are not afraid of making mistake but have courage to explore and full of curiosity in pursueing fancy thing so they strive to find novel, colourful and exuverant vitality expressions. So American slangs is so prevalence in persentday society.

俚语不仅能反映出创造者和使用者的个性和内心世界，而且能折射出社会和文化现象，能反映人们的价值观念，道德规范，思维方式，美国人具有较强的个性，不怕犯错误，勇于探索，充满好奇心，追求和偏爱新奇的东西，因此他们力图寻找新颖有力，绚丽多彩，富有生机盎然的词句，因此美国俚语在当今社会上有着很高的流行度。

The ethical and popular tendency was greatly strengthened. Such a lange-angle swerve is related with the Speech On The Yan An literature Conversazione of Mao Zedong and the situation of the revolution ang politics.It embodied a praticable and strategic intention, and also reflected the complicated attitude of Mao Zedong himself on the modernization.
