In market aspect,MNEs have rigidity of market crowding out,can possess market rapidly and potentially,build the bulwark of market entering,while it also has absolute advantage of brands. At the same time,they also develop a pattern of value chain of vertical specialization,by which,Chinas enterprises may have a chance to get into MNEs global value chain and acquire market room. In industry aspect,while MNEs control the industry by stock property and the advantage of brands,they provide a chance of industrial transfer and industrial linkages. Chinas enterprises could strengthen industrial linkages and achieve industrial drive by technology innovation and agglomeration effect. In technology aspect,because of the nature of MNEs technology monopoly,Chinas enterprises must face the dilemma of technology dependence,technology unadaptability and technology trap. But MNEs may also transfer technology to Chinas enterprises by competition effect,demonstration effect and cooperation effect. Moreover,Chinas enterprises could make use of MNEs investment of "oligopolistic reaction"in China to accelerate technology transfer.

在市场层面，跨国公司对中国企业具有市场挤出的刚性，市场占有速度快、潜力大，构筑市场进入壁垒，具有绝对品牌优势，但也在中国形成垂直专业化分工的价值链模式，中国企业获得链入跨国公司全球价值链，获取自身市场空间的机会；在产业层面，跨国公司借助股权安排和品牌优势实施产业控制，但也提供了产业梯度转移和产业关联的契机，中国企业可以通过技术创新和聚集效应，增强产业关联，实现产业带动；在技术层面，跨国公司出于技术垄断本性，使中国企业面临技术依赖、技术非适应性甚至技术陷阱的困境，但也通过竞争效应、示范效应、合作效应对中国企业进行技术转移，中国企业还可以利用跨国公司在华&寡占反应&投资，加速技术转移。

The invention uses low cost grease which are mainly waste resources such as the unedible Jatropha curcas seed oil, the waster oil in the restaurant industry and the acid value oil, etc. as raw materials, thereby enlarging the material sources; because the Rhizopus chinensis CCTCC M201021 full cell lipase which is extremely low in cost is used as the catalyst, the problem of high price catalyst is effectively resolved; the toxic action of the alcohol on the biological catalyst is resolved by the batching fed-batch the short chain alcohol, thereby improving the conversion rate of the short chain alcohol.

The sizes of the self-assembly micelles of the amphiphilic block copolymers and the effects werestudied by dynamic light scattering and UV-visible spectrophotometer. The micelle sizes werelargely influenced bythe hydrophobic chain content in the copolymer, the properties of the solvent and the copolymer concentration in the organic phase. The morphology of the micelles was investigated by transmission electron microscopy. Theresults showed that the micelles appeared spheres with inner core and outer shell. The critical association concentrations were determined by pyrene monomer fluorescence probe technology. The degradability of copolymer was studied by the loss of the intrinsic viscosity in the degradation process. The results indicated that the degradation rate of PECL was slower thanthat of PELLA and PEDLLA. The stability of the copolymer micelle dispersion was examined by measuring the critical flocculation concentration, which gradually decreased with increasing the content of thehydrophobic chain in the copolymer. The rheological results showed thatthe viscosity ofthe micelle dispersion with higher content of PEG segments was firstly decreased and then increased with the increasingthe temperature. Otherwise, the variation of viscosity was irregular. The viscosity of the micelle dispersion increased with the increase of the electrolyte (Na 2SO 4) concentrations. Polymer micelles paclitaxel was prepared by self-emulsification/solvent evaporation method and solid dispersion technique with amphiphilic block polymers as the carrier material.

运用动态光散射和紫外分光光度计研究了两亲性嵌段共聚物自组装胶束的粒径及其影响因素，结果表明，自组装胶束的形成机理受制备方式的控制，胶束的粒径随着共聚物相对分子质量或疏水嵌段相对分子质量和有机相中共聚物浓度的增大而增大，随着有机溶剂的水溶性的增强而减小；采用透射电镜观察胶束的形态结构，发现胶束呈具有核壳结构的均匀球形；采用芘荧光探针法测两亲性嵌段共聚物的临界聚集浓度；通过降解过程中共聚物特性粘度的变化研究两亲性共聚物的降解性能，发现与PELLA和PEDLLA的相比，PECL 降解速率较慢；随着共聚物中疏水嵌段含量的增大，纳米分散液的稳定性逐渐下降；PEG含量高的PEDLLA纳米分散液随着温度的升高，纳米分散液的粘度先下降然后增大，反之，没有规律性，且随着电解质Na 2SO 4浓度的增大，体系粘度增大。
