无缺点

All of these aspects need to be improved.Considering the disadvantages of the two kinds of the deicers, great amounts of the science data are referred in the research experiment, by developing the main materials and the additives, a new kind of deicer: PAL is founded. Not only does PAL remain the advantages of the traditional deicer such as cheap materials and low freezing point:-43.8 C, but it has the character of CMA, low corrosion to steel and concrete.

针对上述除冰剂的缺点，本课题收集了国内外大量的相关科技文献，通过对主体物料和添加剂两方面的改善，寻找到一种新型除冰剂PAL，它既保留了传统除冰剂的优点，原料廉价易得，低冰点，可达-43.8℃；又兼有CMA的优点，对钢铁几乎无腐蚀，对混凝土无不良影响。

Element-free Galerkin Method is a effective method for solving partial differential equations with the help of shape functions coming from moving least squares approximation. It is well-suited to problems involving large deformation and crack propagation etc on which Finite Element Method can not be used easily. But EFGM is computationally expensive and it is hard to impose the essential boundary condition. Coupling the EFGM and FEM can fetch up the defect of EFGM and improve the efficiency highly.

无网格伽辽金法是基于移动最小二乘法的一种用来求解偏微分方程非常有效的方法，在处理诸如高度大变形、裂纹动态扩展等有限元法较难解决的问题时有其独特的优势，但是存在处理边界条件复杂，计算量大的不足，将无网格法同有限元耦合可以解决这些缺点，极大的提高计算效率。

Cruelty of disposition; malice and ill-nature; that most anti-social and odious of all passions, envy; dissimulation and insincerity, irascibility on insufficient cause, and resentment disproportioned to the provocation; the love of domineering over others; the desire to engross more than one's share of advantages; the pride which derives gratification from the abasement of others; the egotism which thinks self and its concerns more important than everything else, and decides all doubtful questions in its own favour;—these are moral vices, and constitute a bad and odious moral character: unlike the self-regarding faults previously mentioned, which are not properly immoralities, and to whatever pitch they may be carried, do not constitute wickedness.

性情的残忍、狠毒和乖张——这些是所有各种情绪中最反社会性的和最惹人憎恶的东西——妒忌，作伪和不诚实，无充足原因而易暴怒，不称于刺激的愤慨，好压在他人头上，多占分外便宜的欲望，借压低他人来满足的自傲，以"我"及"我"所关的东西为重于一切、并专从对己有利的打算来决定一切可疑问题的唯我主义——所有这一切乃是道德上的邪恶，构成了一个恶劣而令人憎恶的道德性格。这与前节所举只关己身的那些缺点是不一样的。那些缺点正当说来不能算是不道德，不论达到怎样高度也不会构成毒恶。

However, common polyacrylate emulsion has some disadvantages such as poor water-resistance, poor film-forming in low temperature, becoming pastiness in high temperature, polluting environment with emulsifier and so on.

由于聚丙烯酸酯乳液具有耐热、耐光和耐老化等优点在涂料工业中得到了广泛的应用，但普通的聚丙烯酸酯乳液还存在耐水性差、低温下不易成膜、高温发粘以及含乳化剂的废液会对环境造成污染等缺点，因此，本文结合无皂乳液聚合和核壳乳液聚合技术，合成了聚丙烯酸丁酯/丙烯酸钠齐聚物，并以此为乳化剂，采用种子半连续法合成了以聚丙烯酸丁酯为核，聚甲基丙烯酸甲酯-苯乙烯为壳的无皂核壳聚丙烯酸酯乳液。

In this paper, the basic principle and the power factor of conventional SERDS are discussed. Aiming at its shortage of low power factor, boost chopper type SERDS is adopted. The equivalent circuit of the new scheme is built up, and then vector diagram is used to analyze the power factor of the system, also the harmonic distortion of the system is discussed. The experiment device is established base on a 380F/7.5 kW induction motor and a passive soft switching scheme is applied in order to improve the working condition of IGBT. At last, the experimental results are shown.

Suspensorily joined structure has the virtue that the construction progress is normally fast and does not hinder the traffic underbridge because Travelling Carriage is not used,but requiring comparatively large construction plant, high complexity in seam assembling, lower structural integrity compared to the suspensorilyplaced are its faults.

预应力混凝土T型刚构加挂梁结构是公路桥梁常用的一种桥梁结构型式，这种桥型根据施工方法的不同可分为悬浇和悬拼，悬浇结构需采用挂篮施工，优点是结构无干接缝，整体性好，刚度大，施工占用场地少，缺点是施工期间挂篮将影响桥下的通航通车，施工周期长；悬拼结构的优点是无需采用挂篮施工施工进度快，对桥下的通航通车影响较小，缺点是需占用较大的施工预制场地，拼装接缝处理难度大，结构整体性较悬浇差。
