优点和缺点

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。

Based on the comparison of proposed basic topologies, Hypercube, as a popular used topology in networks, has a lot of advantages such as simple routing algorithm, small diameter and average number of internode distance, high fault-tolerance and so on. On the other hand, the network nodal degree which is logarithmically proportional to the number of network nodes limits the Hypercube network population most. So a class of hierarchical topologies are proposed to remedy this weakness of Hypercube and keep most of the advantages of Hypercube, such as CCC , HHC and deCube and so on.

基于对所提出的基本互连网络的性能比较，超立方体网络作为一个得到普遍研究的网络拓扑结构具有很多的优点，比如网络的非常简单的寻路算法，很小的直径和网络平均节点距离，高容错能力等等，但非常遗憾的是超立方体的缺点是超立方体的节点度随着网络规模的增加而成对数关系增加，从而限制了此网络的应用规模，大大地掩盖了它的诸多优点，所以人们提出了一类分层网络结构来弥补超立方体的不足同时最大限度地利用其优点，包括CCC，HHC以及deCube等。

Accordingly three DNA computing models, the solution-based model, surface-based model and the combination of solution and surface-based model, were presented to solve 0-1 programming problem in the study. The advantages of massive parallelism, high-density storage and potential robotization of solution-based and surface-based model were well embodied and their shortages such as timewasting operations and less massive parallelism were also avoided by all means in these models.

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。

摘要传统的测频仪器体积很大，耗能量大，主要靠手工操作，而最大的缺点是不可编程，其量程转换、数据测量、采样控制和处理等均不能通过程序指令来进行控制，无法作为一个微型智能子系统与某一大型自动控制或测试系统进行接口。针对这些缺点，本频率计再设计上作了根本的革新，其优点是：所用核心器件是先进的单片专用测频器件——单片频率计，集成度高，体积小，耗电省，功能强，实现了频率计的高度集成化和微型化；单片频率计只要加上晶振、量程选择、频率显示等很晌慰的器件即可构成一个DC至10MHz的微型基本测频电路；而最大的优点则是本频率计完全实现了单片频率计、频率采样与单片微机三者之间的硬件与软件接口，使得测频量程的选择、频率数据的测量、采样以及编码的边境转换和数据的转储均可能过单片微机的软件编程自动进行，从而实现了测频与采样工作的完全智能化，使得本系统既可独立构成一个微型智能测率仪器的核心电路，也可作为大型自动控制或测试系统中的一个智能子系统。关键词高度集成化，单片机，频率计，电路

The advantage of Servicemix: 1, be based on JBI standard; 2, can heat up deploy; 3, supportive Camel (can develop compositive technological process with DSL); The defect of Servicemix: 1, JBI standard was brought use those who go up is trival, and JBI standard did not gain too much favour, the future was not predicted; 2, depend on the configuration of XML too much; 3, because all messages want to undertake standardizing handling, be generated namely and analytic XML file, can bring about function to drop so; 4, frame of implementation of the need in developing a process is specific interface is received and handle afore-mentioned standard informations, invade a gender strong; 5, documentation is not quite diseased, clear; The advantage of Mule: 1, the framework is simple clarity, easy begin; 2, it has very extensive transmission implement, road by implement with converter, and expand easily; 3, mule does not need to change the word into unified format, and have transition when need only, improved performance; 4, mule code need not pay close attention to in developing a process, need to pass configuration to be able to expose the service only, decreased to invade a gender; 5, documentation is clear and perfect; The defect of Mule: 1, did not implement any ESB standards but abided by " Enterprise Intergration Patterns " with SEDA?

The Place I was in, was a most delightful Cavity, or Grotto, of its kind, as could be expected, though perfectly dark; the Floor was dry and level, and had a sort of small lose Gravel upon it, so that there was no nauseous or venemous Creature to be seen, neither was there any damp, or wet, on the Sides or Roof: The only Difficulty in it was the Entrance, which however as it was a Place of Security, and such a Retreat as I wanted, I thought that was a Convenience; so that I was really rejoyc'd at the Discovery, and resolv'd without any Delay, to bring some of those Things which I was most anxious about, to this Place; particularly, I resolv'd to bring hither my Magazine of Powder, and all my spare Arms, viz.

虽然在洞里没有光线，但这却是一个令人赏心悦目的最美丽的洞穴。地上干燥平坦，表面是一层细碎的沙石，所以不会有令人厌恶的毒蛇爬虫。洞顶和四壁也十分干燥。这个洞穴唯一的缺点是入口太小，然而正是因为进出困难，才使它成为一个安全隐蔽的地方，而这也正是我千方百计寻求的庇护所。所以，这个缺点于我来说反而成了一个优点。我对自己的发现真是欣喜万分，决定立刻把我所最放心不下的一部分东西搬到洞里来，特别是我的火药库和多余的枪支，包括两支鸟枪和三支短枪。
