Using the main result, we also obtain a simple criterion to check if a given mathrm C^*-algebra A is Abelian, that is, A is Abelian if and only for any two positive elements a, bin A, there is a'in A such that ab=ba'.

利用文中的主要结论，还得到了判断 mathrm C^*-代数 A 是交换一个简单条件，即 A 是交换的当且仅当对 A 中的任何两个正元 a， b 存在 a'in A 使得 ab=ba'。

Rat in Group B was set an air bladder which was empty and not perfused water. Water of 0.6 ml, 0.8 ml, 1.0 ml, 1.2 ml, 1.4 ml and 1.5 ml was perfused respectively into the air bladders which were set in the colon of rats in group C, D, E, F, G and H. Then the changes of ethology of the rats were recorded in interval of an hour.

On the other hand, as illustrated in Picture B and D, the price drop would become material objects' price drop because of the continuous flow syphonage capital. Pictures stood by Picture B and D can become anti-syphonage theory pictures. The syphonage pictures and anti-syphonage pictures can simply stand for two converse investment opportunities. Under normal situations, commodity's syphonage capital flow can demonstrate a slow increasing situation in the long run. But the situation is usually affected by supply-and-demand situation in the middle and short run. Especially in the type of gurantee sum exchange, the supply-and-demand situation is a major factor affecting commodity price even in a price dominated market. The commodity's ultimate price will comparatively alter when the outer influence changes, and sometimes the price may change to a completely converse direction as expected. In case of the above case, we need to observe and research the influential factors. However the research is not like the Butterfly Theory research on slight variables. Syphonage theory deems that if continuous observance extends more than a certain percentage, such as 10% influential factor, and we continue researching, immediately putting 10% influential factors into research scale, we could finish the all-round research on commodity price analysis.

其中，图A和C表示的图形我们成为正向虹吸图形，B和D代表的图形成为反向虹吸理论图形，这种正向虹吸图形和反向虹吸图形分别可以简单代表两种相反的投机机会，在正常情况下，商品的这种虹吸资金流从远期看会表现出缓慢的上升走势，但在中短期，走势经常受到供求关系影响，特别在保证金交易的品种中，即使是价格操纵的市场中，供求关系也是影响商品价格的主要因素，这种以供求关系为主导的市场中，虹吸终值并不是一成不变的，在外在影响因素发生变化时，商品终值也会相应变化，有时甚至会改变到和预期截然相反的方向，这就需要我们经常对相关影响因素进行跟踪和研究，这种研究并不象蝴蝶理论分析的微小变动因素，虹吸理论认为只要连续跟踪超过一定权重，比如10％影响权重的因素，并持续研究，及时将超过10％影响因素事件纳入调查范围，既可完成对商品价格分析的全面性探索。

The aim of this study was to investigate the risk of cirrhosis associated with genotype, precore stop codon G1896A mutation and A1762T/G1764A double mutation in the basal core promoter of hepatitis B virus.

本研究乃以前瞻性世代研究法探讨B 型肝炎病毒B、C基因型、precore stop codon G1896A 突变和basal core promoter A1762T/G1764A 双突变对於发生肝硬化的影响。

The results of XRD and DSC showed that ginkgolides existed in solid dispersion at amorphous form or solvates form. The dissolution rate of ginkgolide B in solid dispersion was increased dramatically compared with raw material.

银杏内酯 B从PVP固体分散体中的溶出速率比原药粉末显著提高，且药物中银杏内酯A，B，C和白果内酯从固体分散体中的溶出相似性(f2值均大于 50)优于原药粉末。

In conclusion, the pregnant result of group C was better than group B, D, E.2. The positive substance of TNF-αin group B was significantly increased than group A in the hypothalamus nuclei, neurohypophsis, pars intermedia, ovary follicle, corpus luteum, however, the expression of TNF-αwas obviously decreased in adenohypophysis.

B组TNF-α阳性产物的表达在下丘脑核团、神经垂体、垂体中间部、卵泡、黄体中均较A组显著增高，在垂体前叶较A组显著降低，在卵巢基质以及子宫中的表达与A组无显著差异。

QUITE GOOD就相当于分数A,B只是AVERAGE,"OK","C"则是差,这点Cahill自己在他的评论中都写到了: I might add, finally, that my experience with the British academic grading system as an outside reader for Hong Kong University several years ago made me conscious that your gradings are stricter than ours; a student here would be quite unhappy with a B or 13grade in a seminar, but maybe the same isn't true there.

&我最后想要说，我在几年前做过香港大学的校外分数重估专家，这个与英式学术计分系统的经历让我感到你们的计分法要比我们的严格，在这里严格学术会对一个B和一个讨论课的13 级分数很不满，但是这在你们那里也许不是这样。&同时Cahill 自己已经在他的意见书中承认了他已经了解了有关这个分数和论文的背景，，并且还多次着重指出&From the viewpoint of the instructor…&根据以这个课程的指导教师的观点。。。
