Linkage mechanism of study. Forepart all gather be linkage mechanism structural analysis and agency designer. In recent years so emphasize in kinetic synthesis dynamic and motility analysis. So text needle towards inquire into slider four-bar linkage mechanism agency positioning control.Research emphases are as PID control, fuzzy control, Fuzzy sliding mode control three kinds of controllers for control core. Permeate practical mechanism to positioning control to function. Simple exertion market vends signal extract card (PCL-833) and multi-function card (PCI-1711). Make it make signal extract and bring forth exportation control voltage. Will AC servo motor turn signal, as positioning system point of angle sensor. Reach to slider four-bar linkage mechanism servo positional control research.

连杆机构的研究，早期都集中在连杆机构的结构分析和机构设计，近年来也多著重於运动及动力分析上，因此本文就是针对於探讨滑块四连杆机构的定位控制，研究重点是以PID控制、模糊控制、模糊顺滑模式控制三种控制器为控制核心，透过实际的机构达到控制定位的功能，运用市面上贩卖的讯号撷取卡(PCL-833)和多功能卡(PCI-1711)，使其对讯号做撷取和产生输出控制电压，将AC伺服马达的转动讯号，作为定位系统的角度感测器，达到滑块四连杆机构伺服定位控制的研究。

From the potential energy profile, it can be predicted that, the dominant channel of this reaction consists of three steps: the two reactants first form a three-membered ring intermediate (INT1) through a barrier-free exothermic reaction of 19.2 kJ/mol; three-membered ring intermediate (INT1) isomerizes to a four-membered ring silylene(P2) via the transition state (TS2) with an energy barrier of 22.8 kJ/mol; four-membered ring silylene(P2) further reacts with ethene(R2) to form a silicic bis-heterocyclic compound (P3), which is also a barrier-free exothermic reaction of 132.2 kJ/mol.

用CCSD//MP2/6-31G*方法研究了单重态二甲基亚烷基硅烯与乙烯生成硅杂双环化合物环加成反应的机理，根据该反应的势能面可以预言，该反应的主反应通道有三步组成：第一步是两反应物（R1， R2）首先生成了一三元环中间体（INT1），它是一无势垒的放热反应，放出的能量为19.2 kJ/mol；第二步是三元环中间体(INT1)经过渡态TS2异构化为了四元环硅烯（P2），其势垒为22.8 kJ/mol；第三步是四元环硅烯（P2）进一步与乙烯(R2)反应生成了硅杂双环化合物（P3），该反应也是一无势垒的放热反应，放出的能量为132.2 kJ/mol。

已知崧泽文化中的数字卦虽然没有将二、三、四归并入一、六两数，但它们显然也不可能是徐先生所论&四万六千六百五十六个重卦，二十七万九千九百三十六爻&那种数字卦。

Growth of cultured winged pearl oyster, Pteria penguin was studied in 20 months in Li'an Lagoon, Hainan, south China. The growth parameters of maximum diagonal length, shell length, hinge length and total weight were measured monthly and described using y=y(subscript ∞)/superscript (1+e-k+d sin (2п/365.25).

对海南黎安港的企鹅珍珠贝养殖群体的生长进行了20个月的观察，每月测量其壳高、最大对角线长、绞合线长和总重四个生长指标，并用模型y=y/1+e(上标-k+d sin (2п/365.25)分别拟合这四个指标的生长曲线。

China's major contemporary writer Guo Moruo had to stay in this poem Park Chan said: This is the workers in outer space, sitting height of the clothing Bang Bo Hin, floor-Ge Yue, palaces, eloquent talk about full four Yan, 10,000 Yancha 1000 wine , 3:00 Pianfan four Local tastes from Tokyo.

我国当代大文豪郭沫若曾在此园留诗赞曰：此是工人天外天，解衣磅礴坐高轩，层楼重阁怡宫殿，雄辩高谈满四筵，万盏岩茶千盏酒，三时便饭四时鲜。

Methods Twenty SD rats were randomly divided into two groups. The left phrenic nerve or accessory nerve was transferred to femoral nerve by the vascularized ulnar nerve bridging in Group A and Group B, whereas the right femoral nerve remained the disjunction. The electromyogram and wet weight, throughput and section area of myelinated nerve fibers, and section area of muscle fibers in quadriceps femoris muscle were determined after 24 weeks.

大鼠20只，随机分为A、B两组，每组10只。A组：左侧行膈神经桥接带血管蒂的尺神经转位修复股神经手术，右侧切断神经不吻合，作空白处理。B组：左侧行副神经桥接带血管蒂的尺神经转位修复股神经手术，右侧切断神经不吻合。A、B两组于24周后观察股四头肌电生理、有髓神经纤维通过率及截面积、股四头肌湿重比、肌纤维截面积比等指标。

In the first four years that Montoya has served as mayor of the city of San Perdito, the population has decreased and the unemployment rate has increased. Two businesses have closed for each new business that has opened. Under Varro, who served as mayor for four years before Montoya, the unemployment rate decreased and the population increased.
