Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。

Viewing from the angle of the science of law and taking "rights" as the text for analysis,this article discusses the theoretical divergence on "the rights of nature" between the anthropocentrists and non-anthropocentrism.The anthropocentrists criticize the rights of nature from four aspects,its humanity,impracticality, uncontrollability and non-equivalence of its duties.The n...

从法学视角切入，以&权利&作为分析文本，论述了人类中心主义与非人类中心主义在&自然权利&上的理论分歧，人类中心主义者从权利的属人性、权利义务的不对等性、主张自然权利的非现实性以及自然权利的不可操作性四个方面对自然的权利提出了批判，而非人类中心主义者指出权利概念的在不断地扩展，人类中心主义不可能完全解决好人与自然的关系，自然权利存在着转化为在法律上具有可操作性的可能，并且自然权利理论已在法律实践领域拓展，对自然的权利进行了辩护，由此提出了&非人类中心主义&、&自然的权利&的环境伦理定位。

The application results from fluorination showed microwave heating could accelerate chemical reactions markedly. The reaction time could be shortened 50% at least than that of conventional heating. The relationship between fluorinating agents\' structure and their activity was studied systematically. In addition, an anhydrous KF with higher activity was prepared by using expansion effect of microwave heating. As we known, solvents were very important to reaction. The comprehensive study showed some less polar aromatic solvents could be used as dipolar solvents. In addition, they had better effect than dipolar solvents in some occasions, such as fluorination of chlorobenzaldehydes and chlorinated diphenyl ketones etc. The primary applications of ionic liquids were also studied which indicated reactions with ionic liquids as solvents were more efficient and simple.

研究表明，微波是一种节能高效的加热方式，在微波作用下的卤素交换氟化反应具有反应速度快、转化率高、选择性好的优点，其反应时间可较常规加热缩短50%以上；同时也系统地研究了氟化剂种类及制备方式对其反应活性的影响，并利用微波加热的膨化作用制备出了一种活性较高的KF，其活性与喷雾干燥KF相差不大；溶剂对反应具有重要的作用，在此系统地研究了强极性非质子溶剂和中等极性非质子溶剂的应用情况，发现一些中等极性的非质子溶剂如硝基芳烃和氯代芳烃类溶剂在氯代苯甲醛类化合物的氟化反应中具有比强极性非质子溶剂更好的使用效果。

It is found that the structure of the ternary electroless Ni-W-P coating is greatly influenced by W content in the deposit. It is also found that the requisite content of phosphorus for amorphous Ni-W-P structure is less than that of Ni-P binary alloy coating, and the more tungsten exists, the less phosphorus is required. The hardness of the deposits will be enhanced as the deposit structures are changed from amorphous to mix-or nanocrystalline structures. The corrosion resistance of Ni-W-P ternary alloy is improved as W content increased, and the passivation of amorphous deposits is formed more easily than that of mix-structure and nanocrystalline deposits.
