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。

They had suppressed the cathodic process of carbon steel electrode. Their inhibition performance was also related with their molecule stereo conformation and electron configuration. Four of bis-(1, 1'-benzotriazoly)-α,β-diamide compounds linked via-CO 〓CO-chain were synthesized and certified by IR and 〓H-NMR. The minimum energy conformations of these compounds were obtained by MM2 forcefield program. The two benzotriazole moiety in BBT1 was more planar than in other compounds. This was beneficial in increasing the inhibition effects of BBT1. In 0.5M H〓SO〓 solution, BBT1 suppressed anodic corrosion reaction. In 3%NaCl solution, BBT1 suppressed both cathodic and anodic corrosion reactions. 1- [ (1'-imidazolly)-methyl] benzotriazole was synthesized by Mannich reaction.
