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。

The experimental research found that the serum concentration quenching and absorption effect is not obvious when the experimental sample is excitated by 220, 230 and 310 to 420 nm monochromatic light, and the fluorescence stimulation plays the main role.

实验还发现：当采用220， 230， 310～420 nm波长的光激发时，血清的浓度猝灭和吸收作用不明显，主要是激发出的荧光起作用；采用240～300 nm波长的光激发时，血清浓度猝灭和吸收作用明显，导致荧光强度随着血清浓度的增加变得越来越弱。

Puzzlingly, such effect is transient and depression is usually reinstated after the first episode of recovery sleep, or even after short naps .

睡眠剥夺可能通过改变5-羟色胺(serotonin 5-HT)系统起作用，5-HT_(1A)受体作为突触前的自身受体在调节中缝核5-HT神经元的活性中发挥着关键作用，并且作为突触后受体介导5-HT对边缘系统、皮层、下丘脑及其它一些脑区部位的作用，使得5-HT_(1A)受体的调节对于精神疾病非常重要。

PKC activator PMA simulated the effects, but chelerythrine diminished the 〓 current to the near control level in the HPC cells, suggesting the upregulation of 〓 channels was related to PKC activation, and upregulation of 〓 channels in the HPC cells was also due to PKC activation.

PKC激动剂PMA具有同样作用，而Chelerythrine则能够抑制预处理的这种作用。提示〓通道的上调与PKC的激活有关，而且HPC对〓通道的上调作用也是通过PKC的激活起作用的。

In the first way, the other five medicines except Radix sophorae flavescentis against NDV was better. In the second way, the effect of Herba houttuyniae, Patrinia villosa juss, Rhizoma polygoni cuspidati and Radix isatidis to NDV was better, but Radix sophorae flavescentis and Folium isatidis had little effect. In the third way, Radix isatidis, Herba houttuyniae, Patrinia villosa juss were more effective than Folium isatidis, Rhizoma polygoni cuspidate. In short, the effects of Radix isatidis, Patrinia villosa juss and Herba houttuyniae on NDV were higher.The first of three more satisfactory complex composites obtained from the experiment was Folium isatidis, Herba houttuyniae, Rhizoma polygoni cuspidati, Patrinia villosa juss and Radix sophorae flavescentis.

在第一种加药方式中：只有苦参没有产生作用，其余五种药物抗NDV的作用均较强；在第二种加药方式中：鱼腥草、败酱草、虎杖、板蓝根效果较好，而苦参及大青叶则几乎不起作用；在第三种加药方式中：板蓝根、鱼腥草、败酱草有较强的作用，大青叶、虎杖次之，由以上结果可以看出在三种方式中，板蓝根、败酱草和鱼腥草抗NDV的作用较强。

Plass was aware of the potential for amplifying feedbacks, particularly via water vapor and cloud changes, but the quantification of these effects would have to wait another 10 years for the work of Fritz Mller and subsequently Suki Manabe and colleagues.

普拉斯意识到了反馈可能引起的放大作用，特别是它能通过水蒸气和云层的变化起作用，但还要再等上10年，弗里兹·莫勒才开始定量计算这些作用，随后由真锅淑郎和他的同事接手。

These results suggestthat the antiallodynic and antihyperalgesic effect of NTP onneuropathic pain induced by spinal nerve ligation is mediatedprincipally through the action at supraspinal sites and throughactivation of spinal noradrenergic systems, possibly via thedescending inhibitory pathway.

这些结果提示 NTP 对脊神经结扎导致神经性疼痛的抗痛觉超敏和抗痛觉过敏作用主要是脊髓上作用和去甲肾上腺素能系统的激活介导的，可能是通过下行抑制通路起作用。

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。
