According to the Box-Benhnken design principle,the method of response surface method with 3 factors and 3 levels was used. The factors influencing the technological parameters were determined by means of regression analysis. Response surfaces were finally graphed with the yield as the response value. The synthesis conditions were optimized as follows:reaction reagent was NBS,stoichiometric proportion between NBS and anhydrovinblastine was 1.07; the dosage of TFA was 22 mL/L; reaction temperature was －68 ℃ and duration was 90 min.

在单因素实验基础上，根据Box-Benhnken实验设计原理，采用三因素三水平的响应面分析法，研究了各个因素及其交互作用后，得到了合成7′-Br-脱水长春碱的最佳工艺条件：以二氯甲烷为溶剂，采用NBS为溴代剂，其用量与底物的物质的量比为1.07∶1，TFA的加入量22 mL/L，在－68 ℃下反应90 min，终止反应后，得到卤代产物。

The dissertation puts forward that culture capital as a sort of non-economic element is able to produce tremendous economic value and straightway impel enterprise"s sustainable development, in which main content is that system culture, innovative inspirits, inter-human trust and ecological ethics is the key and core element affecting enterprise development after adopting other subjects" research fruits.

论文提出和界定了文化资本的范畴，认为企业制度文化、企业家的创新精神、企业中的人际信任和企业生态伦理是影响企业发展的深层次因素和核心要素；论文主要吸收和运用了经济增长学说中的文化因素影响论、管理学中的企业文化理论、社会文化学中的人际信任理论和环境经济学中的生态伦理论、制度经济学中的非正式制度理论等的最新研究成果，提出文化资本作为一种非经济因素，也可以创造巨大的经济价值，并直接推动着企业的持续发展。

METHODS Among 204 patients reinfected after PIC window 104 patients with short PIC window and 100 patients with long PIC window were prospectively studied. According to univariate analysis and logistic multivariate regression analysis the influential factors with PIC window were identified.

方法对204例出PIC窗后再感染者中，104例较短PIC窗的患者和100例较长PIC窗的患者进行前瞻性调查，以单因素分析及Logistic多因素回归分析，判定PIC窗的影响因素，并与100例出PIC窗后未再感染者进行对照研究。

Equity structure decides how the resident rights of benefits and control divided among the investors, different equity structure shows that the benefits and rights are scatted among different investors, it will lead to different corporate governance and different firm value, so it is really related with firm value. At the same time, other factors include the outside environment of the firm and the firm itself also gives important effect on firm value.

股权结构决定着剩余索取权与控制权在利益主体中的分配，不同的股权结构表明不同的利益及权力分布，不同的利益主体在企业中的地位与投资目的不同，会使治理机制发挥不同的作用，从而表现出不同的企业绩效，所以，股权结构与企业绩效息息相关；而非股权结构因素包括企业外部环境因素和企业自身因素，也对企业绩效产生重大影响。
