In this study, we investigated the expression of osteoblast differentiation and osteoclast differenation by adlay extract, benzopyrene and tributyltin, three environmental estogens.

在本实验中，我们观察三种环境雌激素样物质：薏苡仁水萃取物、苯骈芘及三丁基锡对造骨细胞和破骨细胞分化的影响。

According to our results, since BaP increased the expression of COX2 and pp38 to reduce the osteoblast differentiation and this phenomenon can reverse by treatment of NS398, but not by treatment of SB203580, suggesting that COX2 activation plays an important role on osteoblast differentiation. Adlay could increase osteoblast differentiation, in co-culture system, and reverse the osteoporotic status in mice, would be a helpful healthy food for enhance osteoblast differentiation. However, about, TBT, we didn't have enough data to support its effect on the differentiation of osteoblast or osteoclast.

所以依据我们所做出的实验结果，虽然苯骈芘会增加COX2和pp38的蛋白表现，但造骨细胞的分化作用仍下降，但若同时添加NS398，则分化能力有恢复现象，这或许可推测说COX2活性在抑制造骨细胞分化上扮演了一个重要角色；薏苡仁在共同细胞培养可以增加造骨细胞的分化作用，且对骨质疏松状态的小鼠具有缓解的能力，因此或许是能促进造骨细胞分化的营养食品；至於三丁基锡由於实验的数据不多，推测其或许并不影响造骨细胞和破骨细胞的分化作用。

Adlay is a grass crop which has been used in traditional Chinese medicine and also as a nourishing food. It has been shown to posses anti-allergic, antimutagenic and hypolipemic effects. BaP is a known environmental pollutant which causes oxidative stress, carcinogenic and mutagenic compound. TBT is widely used as antifouling paints, agriculture biocides, and plastic stabilizers around the world, resulting in great pollution problem in aquatic environments.

薏苡仁属於草本植物，已经被使用在中药方面且也是一种食物，具有抗过敏、抗突变及降血脂的能力；苯骈芘是已知会提升氧化压力具有致癌及致突变性的环境污染物；而三丁基锡是被广泛添加在抗海洋生物的油漆、农业的杀虫剂及塑胶稳定剂里的成分，其在近年对海洋水生环境造成了相当大的污染问题。

The hydroperoxide may be decomposed by Cu2+ to form alkoxyl free radicals,which increased the rate of the whole reaction.In the meanwhile,1-butyl-3-methylimidazolium hydroxide was studyed for the oxidation of cumene and DIPB.

The best operational parameters were that the reaction temperature was 105℃, the reaction time was 3 hours, the mixture ratio of n: n=1:2.79, using N,N-dimethyl benzylamine as catalyst, and 2,6-Di-tert-buthyl-p-cresol as inhibitor.

The factors which affect the average molecular weight of the polymer of AM and DMDAAC were investigated. The optimal reaction conditions are as follows: the concentration of monomer AM was 30%, while DMDAAC was 5%; the reaction temperature was 30℃, the amount of initiators at the low temperature stage was 0.05‰(compared to the weight of the monomers joining the polymerization), while V-50 was 0.025‰, the weight ratio of potassium persulphate to sodium bisulphite is 1:1, the amount of carbamide was 40‰, and complexing agent was 0.05‰, besides, aerate nitrogen gas for 8min, then the high molecular weight polymer (M=1.217×10^7) could be got after 16h reaction.

研究了影响AM与DMDAAC共聚物的平均分子量的因素，得到了优化条件为：单体浓度为30%，DMDAAC与AM摩尔比为5：95，聚合温度为30℃，低温段引发剂用量为0.05‰，K2S2O8与NaHSO3质量比为1：1，偶氮二异丁基脒盐酸盐(V-50)用量为0.025‰，尿素用量为40‰，乙二胺四乙酸二钠(EDTA-2Na)用量为0.05‰，在此优化条件下聚合反应16h后得到分子量为1.217×10^7的阳离子型聚丙烯酰胺。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
