Result: At most up to 500 mg·L-1, tetrahydropalmatine showed no sinificant effect on the cell viability, while dehydrocorydaline, berberine and palmatine significantly decreased the cell viability, exceeding 6.3, 0.6 and 6.3 mg·L-1, respectively（ P .05 or P .01）. Tetrahydropalmatine, dehydrocorydaline, berberine and palmatine significantly inhibited LDH leakage induced by anoxia-reoxia injury, at concentrations of 50-100, 1.25-5, 4 and 30 mg·L-1, respectively（ P .05 or P .01）. None of the four compounds showed significant effect on the hydrogen peroxide injury.

结果：多至500 mg·L-1的延胡索乙素对细胞活力无任何影响，脱氢紫堇碱、黄连素、巴马汀分别在质量浓度大于6.3， 0.6，6.3 mg·L-1时，显著降低细胞活力（ P 。05， P 。01）；延胡索乙素、脱氢紫堇碱、黄连素和巴马汀分别在质量浓度为50～100， 1.25～5， 4，30 mg·L-1时，显著抑制缺氧复氧导致的LDH漏出（ P 。05， P 。01）；4种单体对过氧化氢损伤无显著的保护作用。

Cymes densely dichasial, up to 1 cm; peduncle 2-3.5 mm; pedicels ± absent.

聚伞花序浓密二岐，可达1厘米；花序梗2-3.5毫米；花梗多少无。

Up to day, the batch process of producing chloroacetic acid is still extensively used in our country, by which byproduct dichloroacetic acid comes out while chloroacetic acid beingproduced.

控制反应体系中氯乙酸含量不超过30%，最终所得产品氯乙酸含量达98.5%，二氯乙酸含量小于0.5%，以目前实验装置24小时可得氯乙酸2.938kg。

The growth rate and enzyme activities significantly decreased when dikaryotic hypha ofPleurotus ostreatus were irradiated with γ-rays and subsequently treated with either caffeineor Na2-EDTA in comparison with γ-rays treatment alone. The inhibition effect of treatmentwith either caffeine or Na2-EDTA before irradiation was more obvious than that after irradi-ation. Treatment with either caffeine or Na_2-EDTA could cause biological damages on hyphawhen the concentrations of caffeine and Na_2-EDTA were up to 0.5 and 1.0mg/ml respective-ly.

侧耳双核菌丝经γ射线辐照后用咖啡因或Na＿2－EDTA处理，其生长速度和漆酶及多酚氧化酶活性较单一γ射线辐照明显降低，使辐射损伤加剧；辐照前用咖啡因和Na＿2－EDTA处理，抑制辐射损伤修复的效果优于辐照后处理；咖啡因和Na＿2－EDTA浓度分别达到0.5和1.0mg／mL后，单独处理侧耳菌丝会直接引起生理损伤。

The experimental results show that it could reduce viscosity and shearing force of mud.When the addition of viscosity reducer is 0.5%,the thinning rate at high temperature will be up to 91.4% for fresh water clay mud.And it has very good salt tolerance and calcium tolerance.It has good viscosity reduction and disgregation in saturated saltwater mud and calcareous mud.Its thermal stability is also good.

研究结果表明：研制的钻井液降黏剂可以显著降低泥浆的黏度和切力，加入0.5%降黏剂的淡水基浆，高温降黏率可以达到91.4%；具有较好的抗盐、抗钙性能，在饱和盐水泥浆和含钙泥浆中也具有很好的降黏作用和分散作用；具有较好的热稳定性。

其以下从外侧支发出的穿支数可多达3个，每间隔1.5～4cm发出穿支。

Ing method. We found, after statisticsing the 91 tested preface classification data′s result, that Stress=0.13481＜0.20,DAF=0.86519＞0.60,and the model draws up to match well and has the certain rationality. Organizational management structure of the Jin-merchant in the Ming and Qing dynasty could be divided into five dimensionali?鄄ties:(1)the form of inspiritment methods is diverse;(2)the personnel system is enlightened;(3)the principle of the personnel selecting is objective and strict;(4)strategic measure of human resource can keep on the develop?

在对91名被试的有序分类数据结果进行统计处理后发现，Stress=0.13481＜0.20，DAF=0.86519＞0.60，表明模型拟合良好，具有一定的合理性，且明清晋商组织管理的结构可分为5个维度：（1）形式多样的激励手段；（2）开明的用人制度；（3）客观严格的选拔理念；（4）可持续发展的人力资源战略措施；（5）严格规范的制度与考核管理。
