Methods The levels of serum Hcy, folate acid and VitB12 were measured in 169 patients with cerebral infarction and 110 normal controls. The condition of carotid arteries was checked by color dopper flow image in CI group. The relationship between the level of serum Hcy and folate acid, VitB12 and CAA condition were analysed. The change of serum Hey level was observed after intervention treatment of folate acid and VitB12 for 4 weeks in CI patients with hyperhomocysteinaemia.

In order to complete the investigation, impersonality feasible experiment solutions and devices are designed independently to systemically investigate on activation and transfer characteristic of soil heavy metal under acid rain effect. Primary results are shown as followings:1. PH measuring results of soil solution and eluviation solution show that the ability of experimental plot the acid buffer capacity of soil is stronger under the experiment condition,there is no obvious acidification in soil which after acid rain eluviation.The result has substantial differences with that gotten by most of investigationers in similar work before.

这一结果与以往类似研究中多数研究者得到的结论存在本质区别，原因可能在于此次试验的试验条件与以往研究的试验条件不同，其中最主要一点是在本次试验中使用的土壤样品的重量比以往试验均显著增大，而且使用的是土壤结构和组成等均未经破坏的原位土，从而使入渗酸雨与承受酸雨沉降的土壤之间的比例关系更接近自然酸雨沉降过程，以此为基础得到的试验结果应该更加客观、可靠。2、酸雨对盐基离子活化迁移产生的影响勿庸置疑，但是，在盐基离子活化迁移的过程中，并没有出现预想中的重金属元素活化迁移现象，表明土壤中的重金属元素并不如理论分析的那样对酸雨沉降反应敏感。

After esterification, the ethyl-2-chloro-3-phenylpropionate reacts with diethyl malonate under the catalysis of sodium ethylate, and we obtain the corresponding triethyl ester. The-benzylsuccinic acid is formed by the triethyl ester reacting with concentrate hydrochloric acid and taking place hydrolyzation and decarboxylation reaction at the same time. In order to avoid the formation of cinnamic acid, the sodium ethylate and diethyl malonate must be react sufficiently. The course has simple operation, inexpensive materials and better yield.
