When World War II ended the nucleus has lost US just to start Mai Hadu to plan the initial significance, it turned one kind of capital one kind to threaten for 0.6 ten years American and Soviet law China and Britain one after another to become five macronucleus great nations from now on, afterwards faces by India and Pakistan has one after another, but at the present Iran really for joins this ranks diligently 0.20 centuries speaking of the humanity without doubt is the multi-disaster century, is a war first, lets the humanity be involved in to front no death and the pain despairs, as soon as then follows is standing lives (death which the Madrid flu it creates to surpass a war fatality count) the humanity to fall into panic to, at the same time human cultureFaced with unprecedented test, but this kind of test still was continuing in fact, this tradition impelled the world with the non-traditional strategy balance to face the multistage development, finally caused the individual local conflict to be unceasing.

当二战结束时核已失去美国刚启动麦哈顿计划最初的意义，它已变成一种资本一种威胁。六十年过后美苏法中英相继成为五大核大国，之后以印巴朝相继拥有，而今伊朗真为加入该行列而努力。二十世纪对人类而言无疑是多灾的世纪，先是一战，让人类卷入到前所没有的死亡和痛苦绝望中，接着是伴随着一站而生马德里流感（其造成的死亡超过一战死亡数）人类陷入到更加得恐慌中，与此同时人类文明也面临着前所未有的考验，而事实上这种考验仍在延续，这种传统与非传统战略平衡推动着世界朝着多级化发展，最终导致个别地区争端不断。

The results of simulation provided the base of the experiment in the next step.The solvent, the VLE data and the simulation results in this paper supplied the foundation for the medium scale plane and industrilazation of mesitylene.

本文提出的溶剂、二元及三元汽液平衡数据及模拟结果为萃取精馏法生产均三甲苯的中试及工业化应用提供了理论依据。

The basic idea was to discrete the structure and find the load function according to the energy criterion of buckling and the principle of random displacement method. As the critical load is the minimum of the load function, a problem of frame buckling can be transformed into an optimization problem. Therefore, the critical load can be found through solving the optimization problem.

先将结构离散为一个有限自由度系统；然后根据有限自由度系统平衡稳定性的能量准则和随机位移法的基本原理，建立符合能量准则的载荷函数，该函数不为零的最小值即为临界载荷，由此将稳定问题转化为无约束的多维优化问题；最后应用遗传算法求出相应于最优解的目标函数值。

Fifty female patients who were selected to schedule for mammary gland tumor excision surgery, were divided into 2 groups(n=25 in each group): group A: received propofol's half-effective concentration at 3.0 μg/ml in Marsh model by TCI; group B: received propofol's half-effective concentration at 4.0 μg/ml in Marsh model by TCI. All patients were given remifentanil in Minto model by TCI after being given propofol which reached the balance between effect-site concentration and blood plasma concentration. The target concentration of remifentanil was determined by a modification of Dixon's up-and-down method. Laryngeal mask insertion was attempted after 10 mins, the insertion condition and success rate were observed, then the suitable target concentration of remifentanil(ECe50) were calculated.

50例女性乳腺良性手术患者随机分为2组（n=25），A组：靶控输注丙泊酚效应室浓度3.0 μg/ml；B组：靶控输注丙泊酚效应室浓度4.0 μg/ml（均为Marsh药代模型），待其效应室浓度和血浆浓度达平衡后给予靶控输注效应室浓度瑞芬太尼，运用Dixon's序贯法确定喉罩置入时瑞芬太尼浓度，10分钟后置入喉罩并观察喉罩置入条件与成功率，计算出相应的瑞芬太尼适宜靶浓度（ECe50值）。
