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。

First, the state～space equation of the circular inverted pend ulum system was established based on the Lagrange Equation. On the base of that, the circular inverted pendulum was swung up by the energy control strategy, and the controller of the system was designed by the pole placement of the optimal control theory. Second, in order to realize the observation for the unknown vari ables, stable state observers were designed based on the equivalent principle of sliding mode variable structure.

该方案在采用 Lagrange 函数建立状态空间方程的基础上，利用能量控制策略实现自动起摆；采用最优控制理论中的极点配置法设计倒立摆系统的控制器；同时利用滑模变结构的等值原理设计观测器，实现对系统未知状态变量的观测。

It deals with the invention and development of time-keeping apparatus in our country during a historical period of some three thousand years, tracing this development from remote antiquity with its sundial and clepsydra making use of the shadow of the sun down to the Dynasties of Han, Sui, Tang and Sung with their water-powered astronomical clockworks...

自远古利用日影的圭表和日晷起，中间经汉、隋、唐、宋等朝代，附装在水力天文仪器上的水力天文钟，都采用了齿轮和凸轮的传动，即已都属于机械性。元代郭守敬以后，到明初的詹希元，更发展到独立时钟机构，並有了指针和表盘。可是近四百年，即自明代万历年间，西洋的自鸣钟传来我国，我国在计时器方面的工作，始终在模制阶段，自己的发明遂归于停顿。那次会议闭幕以后，会中曾用英文出版一次，我国1956年12月，《天文学报》4卷2期用中文出版一次。现在根据一些新资料，重新加以增删和改正。

Two jack screws must be provided in windows and die section for ease of removal. All sections that do not have jack screw holes must have pry slots.

The radius of the punch and die cutting edges is laid out to produce the desired circular shape without nicking into the circle as the work proceeds .

在工作过程中，冲头与凹模切口的半径定位，确保形成所需的圆形，而不至于在圆边产生&缺口&。起毛促进起球。

If the blank is wrinkling on the blank holder surface, the cause is most likely one of four factors: insufficient blank holder force; a poor fit between the die face and blank holder surface; an equalizer block that is holding the die face apart from the blank holder surface; or severe blank holder deflection.

褶皱起因于不充分的拉伸或失去控制的压缩变形。如果板料在压边面上起皱，绝大多数起因是后面四个因素之一：不充分的压边力；凹模和压边圈表面不良的匹配；凹模和压边圈间的平衡块；或者是压边圈的严重变形。
