As examples of applying our method, the quantum vacuum effect induced by two moving boundaries is studied in the case where the two mirrors oscillate resonantly.

把求解具有单动边界时的Moore方程的数值方法推广到双动边界情形，提出了广义Moore方程的数值求解方法。

Methods Thirty eight patients with loosening of hip prosthesis were divided into three group: total hip arthoplasty, double hip arthuplasty and integrated arthoplasty. The inflammative reaction was analyzed with light microscopic observation arrording to the half-ration standard of Joseph, and the content of TNF in samples of interface membranes was determined.

方法］根据假体的类型及假体中是否含有聚乙烯将38例人工髋关节翻修病例分为3组：全髋置换组、双动头组和一体式单动头组，对各组术中松动假体周围界膜组织进行光镜下炎性细胞计数的半定量分析和肿瘤坏死因子的测定，分析人工髋关节无菌性松动与聚乙烯微粒、细胞因子之间的相关关系。

［目的］研究聚乙烯微粒、细胞因子与人工髋关节松动的相关性［方法］根据假体的类型及假体中是否含有聚乙烯将38例人工髋关节翻修病例分 3组：全髋置换组、双动头组和体式单动头组，对各组术中松动假体周围界膜组织进行光镜下炎性细胞计的半定量分析和肿瘤坏死因子的测定，分析人工髋关节无菌性松动与聚乙烯微粒、细胞因子之间的相关关系。

One is Bardina vorticity modification, and the other is Richardson number modification. Prediction results show that Bardina method has a superior capacity to Richardson number modification. Since DSM model has improved predictive results of the reversed velocity and tangential velocity, it is a potential method to predict strong swirling nonisotropic turbulent flow in stead of the longer convergence time.

本文采用了基于旋转体系使湍流脉动加强和削弱两种作用的修正方法对k-ε双方程的湍流耗散率方程进行修正，计算结果表明，从旋转体系可使湍流能量加强出发的Bardina涡量修正方法，预报回流区范围缩小，更加接近于试验值，其计算结果优于使湍流脉动削弱的Richardson修正。

Based on the language materials collected, the third chapter analyses the understanding restriction conditions of "VP+NP_1+DE+NP_2" ambiguity structure from the NP_2"s life and the VP"s mobility. The author comes to the following conclusions: the NP_2"s life rank with the "VP+NP_1+DE+NP_2" structural ambiguity in understanding becomes the correlation dependence, the monosyllable verb which expresses the hands" and the foot"s movement, easily combining with the tense auxiliary, enter the "VP+NP_1+DE+NP_2" structure to form the latent ambiguity structure; the double syllable verb which has the causes feature is easy to enter the"VP+NP_1+DE+NP_2" structure to form latent ambiguity structure; the double syllable "noun-verb", with the influence of the behind noun NP_1, both can be understood as the valency combination, and the non-valency combination, thus causes the "VP+NP_1+DE+NP_2structure to appear ambiguity.

在第三章中，我们将在语料分析的基础上分别从NP_2的生命度和VP的动性这两方面探讨这一歧义结构在理解上的制约条件：NP_2的生命度等级与&VP+NP_1+的+NP_2&歧义结构理解为偏正结构的几率成正相关关系：表示手、脚等的单音节动词容易与时态助词结合，进入&VP+NP_1+的+NP_2&结构形成潜在的歧义结构；带有致使特征的双音节动词容易进入&VP+NP_1+的+NP_2&结构形成潜在的歧义结构；双音节的&名动词&由于受其后所跟的名词NP_1的影响，既能理解为配价组合，又能理解为非价组合，从而使得&VP+NP_1+的+NP_2&结构出现歧义。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.
