Due to the ability of the bivalent magnesium cation to form stable chelate complexes with carbonyl compounds,magnesium methylate for example is used as a selective carbonyl condensing agent. Three synthesis routes was proposed based on literatures and comprehensive comparison with other ways. First,Magnesium methylate is prepared by reacting magnesium metal with dry methanol.The magnesium salts of"higher"primary alcohols,i.e.alcohols with ≥ 2 carbon atoms,do not react directly with pure alcohols under normal conditions.In fact catalysts are required to set the reaction in motion and the preparation is performed under pressure at the higher temperatures.

一、直接合成法：本文将镁与无水甲醇直接反应制得甲醇镁；"更高级"的醇（比如C≥ 2的醇）在无催化剂的条件下无法直接和镁进行反应，本文以CCl4为催化剂将无水乙醇与镁直接反应制得乙醇镁，但是以原甲酸三乙酯为催化剂无水乙醇与镁无法反应；不论是以CCl4为催化剂还是以原甲酸三乙酯为催化剂，丙醇均无法与镁直接反应。

objective: value the no tention hernia ring padding neoplasty in treating inguinal hermia.method: retrospectively analysize the clinical data of the no tention hernia ring padding neoplasty.result:the average time of the neoplasty is 40 minutes,the patients can make out-of-bed activity ,whom were treated after 6 hours.all of the patients were free of infection.2 patients felt foreign body sensation in inguinal groove and 1 person felt benumbed.conclusion: no tention hernia ring padding neoplasty is a valuable type of neoplasty,which operates simply,and the patients can get little injury ,rapid recovery and low relapse rate.

目的：探讨无张力疝环填充式修补术在腹股沟疝手术中的应用价值。方法：对30例腹股沟疝患者行无张力疝环填充式修补术后的临床资料进行回顾性分析。结果：手术时间平均40 min，切口疼痛2 d～7 d，术后6 h下床活动，无感染病例，腹股沟异物感2例，麻木1例。结论：疝环填充式无张力修补术是一项更符合生理解剖结构的治疗技术，操作简单，损伤小，恢复快，复发率低。

Results The recovery time of frontal muscle and orbicularis between twist and non-twist in I/t curve and in sex was not significant.

结果 额枕肌额腹和口轮匝肌I/t曲线有扭结与无扭结者的恢复时间、性别无显著性差异；将I/t曲线左移限定在轻、中及重度，有扭结与无扭结者的恢复时间亦无显著性差异；扭结率以中度病变最高，其次是轻度病变口轮匝肌，而I/t曲线左移程度与恢复时间有非常高度显著性差异（ P〈0.001）。

Her chest pressure is constant, moderate in intensity, nonradiating, nonpleuritic, and nonpositional. She has no paroxysmal nocturnal dyspnea, orthopnea, or lower-extremity edema.

患者胸部压迫感呈中度持续性，无放射，与呼吸运动和体位无关，无夜间阵发性呼吸困难，无端坐呼吸，无下肢水肿。

Secondly, point out that meshless method is different from finite element method in handling boundary condition and numerical integral because the approximation function of meshless method is not inserted function, it have itself special methods. Deduces meshless Galerkin essential equation of parabolic partial differential equation with the method ofweighted residuals------Galerkin. Furthermore, discusses the main factors which may effectthe calculation precision and give some suggestion with which can get the best result.

其次，由于无网格法的近似函数不是插值函数，所以无网格Galerkin法在处理边界条件和对区域积分时是不同于有限元的，它有其独特的处理方法，从加权残量法——Galerkin出发，推导出抛物型偏微分方程无网格Galerkin法的基本方程，并对影响无网格Galerkin法的主要因素进行探讨，给出了取得最佳效果的相应建议。

There were very significant differences about the values of MP, MPF and AEMG among the motion muscles, but there was no significant difference about the singals of MF slope, MPF slope and AEMG slope. In patients group there were significant differences about the values of MF, AEMG, AEMG slope of motion limb between paretic side and non-paretic side. There were also significant differences about the values of MPF slope between paretic side of the patients and left side of the health. But there was no significant difference about other parameters in groups or among groups. Compared the activity muscles of four groups, there were significant difference about the values of AEMG and MPF among initiative muscles, antagonistic muscles and co-contraction muscles. There were very significant differences about the values of MF and MPF among co-contraction muscles, but there was no significant difference between initiative muscle and antagonistic muscle.
