But the relationship of amylose and amylopectin contents to SSS and GBSS activities was different according to filling stages.

籽粒SSS和GBSS对淀粉合成的调节作用具有明显的时期特异性，SSS主要在籽粒灌浆前期起作用，而GBSS主要在籽粒灌浆后期发挥作用。

Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.

结果表明，1，拟南芥AtSIRT1与人的同源蛋白hSIRT4相同，定位于线粒体，可能参与呼吸作用和电子传递，SIRT2与人的同源蛋白hSIRT6相同，定位于细胞核，可能同它的功能类似，在延缓衰老及调节细胞寿命方面起作用。2，AtSIRT1突变，可引起幼苗和植株的子叶变黄和早衰；AtSIRT2突变，可引起叶片发紫，沉积大量花青素。3，SIRT蛋白的抑制剂Sirtinol不能表型模写AtSIRT1和AtSIRT2突变体，说明Sirtinol在拟南芥中的作用机制不同于其他生物。4，AtSIRT1和AtSIRT2蛋白质结构预测表明与已知的Sir2蛋白相似，揭示其功能的相似性。5，在大肠杆菌中过量表达了其中一个基因(AtSIRT2)，可体外检测其酶学活性，进一步证明其功能。

Our self-defensive counter-attack on Viet Nam has brought us victories both military and political, and has been a major, long-term factor both in stabilizing the situation in Southeast Asia and in carrying on the worldwide struggle against hegemonism.

对越自卫还击战，在军事上、政治上都得到了胜利，不仅对于稳定东南亚局势，而且对于国际反霸斗争，已经起了重大的作用，将来还会起作用。

But the blood poison is ,so to speak,is a new product from an improved formula.be that as it may,the nerve poison dees it business with man for more quickly than blood poison.this,however,means nothing,the snakes do not acquire their poison for use against man but for use against their pray such as rats and mice,and the effects on those of viperine poison is almost immediate.

不过，神经毒辣液比溶血性毒液在人身上起作用快得多。但是，这没有什么关系，因为蛇有毒液不是用来对付人的，而是对付它的猎物，诸如鼠类，毒液对这些猎物会立刻起作用。

Alexander has demonstrated an iodide peroxidase in animal thyroid tissue and believes this enzyme is responsible for the iodination reactions through formation of an oxidized iodinating intermediate.

Alexander已经证明在动物甲状腺组织中有一种加碘过氧化物酶，并相信该酶对加碘反应起作用，它是通过形成一个氧化态的碘中间体而起作用。

The experimental data demonstrated that there was a nasalward directional preference in oath OKN system under both close loop and open loop conditions, and the nasalward OKN gain evoked by stimulation of nasal retina was much higher than that at temporal retina. ms indicates that OKN nasalward preference is mairily derived from the nasal retina, i. e. the direct path1Vay of OKN dominates the indirect pathway in cat's OKN system. The gains of temporalward and nasalward OKN from temporal retina are much less than those of nasalward OKN from nasal retina. It is suggested that the indirect pathway of OKN in the cat only possesses a supplementary function, Which probably plays an important role in temporalward OKN eye-movments in relation to binocular vision.

实验结果显示：高速度刺激的闭环OKN反应及开环OKN反应均对鼻向运动刺激有明显的方向选择性；半侧视网膜刺激时，鼻侧半视网膜的鼻向OKN增益明显高于颞侧半视网膜的鼻向增益，说明猫的OKN眼动反应以跟踪鼻向运动为主，并且这种对鼻向运动刺激的选择性主要来源于鼻侧半视网膜，亦即来源于OKN直接通路；颞侧半视网膜的鼻、颞向眼动增益均明显低于鼻侧半视网膜的鼻向眼动增益，说明猫的OKN系统的间接通路在OKN眼动控制中起辅助作用，并可能主要对颞向OKN眼动起作用从而与双眼视觉功能相关。

A normal concentration of calcium ion in perilymphatic fluid is necessary for outer hair cell to produce DPOAE.

提示外毛细胞在产生DPOAE中并非以毛细胞的电运动性机制起作用，而是与一般肌纤维相似的收缩机理起作用，需要钙离子的中介。

We already have an idea that the cecum in some animals works the same way," he said."But how, for example, do biofilms work in frogs and other species with no cecum and no appendix?

他说：&我们已经有了这种想法，就是盲肠在一些动物体内起作用的方式与人相同，但是譬如青蛙以及其他一些没有盲肠或阑尾的物种，生物薄膜又是如何起作用的，目前不得而知。&

Chengdu University of Technology Institute of Information Engineering Professor Zhang Zhenggang: I use this hand-wash water, once seen, but in the light side does not work, the role of Mao's side, and immediately show out.

成都理工大学信息工程学院章正刚教授：我用这个手沾上水，马上就看出来了，可是在光的那一面不起作用，毛的那一面起作用了，马上就呈现出来了。

Top research on how self-explanation plays a role in the teaching of chemistry concept; whether self-explanation also contributes to acquiring other kinds of knowledge (knowledge on chemical element, reaction principle); whether it also has a function In other principles etc.

在本研究中由于各方面的原因，本研究还有一些问题需要在后续的研究中完成；从深层次上研究自我解释如何对化学概念的教学起作用；自我解释是否在其他知识(元素化学物知识、反应原理)中也有作用；在其他学科中是否也有作用等等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
