This design installs the process to the road bridge in the space knothole porterage work request, design a kind of new derrick - build a bridge the Dragon gate derrick of liquid press the system, build a bridge the Dragon gate derrick to mainly be constitute by four parts, namely:Rise to rise the organization, small garage to walk organization, change direction the organization and big garages to walk organization.

本设计针对路桥架设过程中博格板的搬运工作要求，设计一种新型起重机械——架桥龙门起重机的液压系统，架桥龙门起重机主要由四个部分组成，即：起升机构、小车行走机构、转向机构和大车行走机构。

Methods: Panax ginseng and Panax ginseng fruit were grinded into powder, placed in the flask and pretreated with the solution of HNO3-HClO4 (4:1) on the electric heat plate. The contents of Zn, Cu, Mn, Fe, Ca, Mg, Cd, K and Na were determined by flame atomic absorption spectrometry.

将人参和人参果粉碎后置于锥形瓶中，分别在电热板上经硝酸－高氯酸(4：1)消解体系小火加热消解后，采用空气－乙炔火焰原子吸收光谱法测定。

The superficial blood vessels could cross two or more pulmonary lobules, and the pleural superficial blood vessels and the interlobular blood vessels were mutual transitional. The outlines of lobules composed of vascular networks were various in size and form, and the lobular septa were also different in depth. The subpleural arterioles could be divided into arteriole, terminal arteriole, precapillary arteriole and capillary in turn according to the branching sequence of themselves. The plate-like, sieve-like and web-like vascular networks occurred in the subpleural microvascular networks.

胸膜面浅层的血管可以跨越两个或多个肺小叶表面，浅层的血管可与小叶间隔的微血管之间相互移行；由微血管网形成的肺小叶的轮廓大小不等、形态各异，小叶间隔的深度也有所不同；胸膜下微动脉可根据逐级分支的顺序将其分为微动脉、终末微动脉、毛细血管前微动脉和毛细血管；胸膜下毛细血管网中可见板块状、筛网状和网络状血管网。

Wang Huifang of Shenzhen bourse researcher published 2006 " from do poineering work to grow -- first selection Shenzhen does poineering work board 23 preelection company grows with changes " point out, in the element that medium and small businesses develops, level of management is very fundamental.

Based on equaling the semi-rigid connecting as the reduction of member end section bending stiffness,an optimization equivalent method is put forward on the principal of minimizing the error term between stiffness matrix of fined model and one of equivalent simple model.In this dissertation,structural fatigue cumulative damage and residual life assessment of wind-induced fatigue safety prewarning system is studied.S-N curve method and fracture mechanics method for fatigue analysis are discussed.

本文建立了高耸塔架结构中广泛使用的螺栓节点板联结节点的精细有限元模型，提出了一种优化等效的方法，以刚度矩阵的误差最小为等效原则，在把节点处杆件的半刚性联接等效为杆端截面抗弯刚度下降的基础上，得到了螺栓节点联结杆件的精细有限元模型与简化有限元模型的等效关系。

In fact, when the press print Screen key, the current image is saved to the system clipboard, just open the "Paint" program, press "Ctrl + V" key combination to paste over the.

其实，当按下print Screen键后，当前的图像被保存到了系统的剪切板中，只要打开"画图"程序，按下"Ctrl+V"组合键即可粘贴过来了。

this paper introduces a lossless detected circuit system.firstly,system gathers slender infrared signal with transducer,then amplifies them with low noise.through voltage comparator circuit,transforming simulation objection signals to digital signals.finally,transforming transport landscape orientation and portrait to single chip processing.in design of pcb,the amplifying of quadruplet signal,filter,voltage comparator decree and and logic function are manufactured in one board.if the diameter of workpiece is long,it can add multiple the number of transducer of four,to wide its range of practice,disposing circuit only need one module.

摘 要：介绍了一种无损检测的电路系统。系统首先利用传感器采集到微弱的缺陷信号，再将缺陷信号进行低噪声放大，然后通过电压比较判决电路将模拟缺陷信号变换成数字信号，最终将横、纵两路的输出信号送至单片机处理。在pcb设计中，将四路信号的放大、滤波、电压判决以及与逻辑功能做在一块板上，若被检测工件的直径较大，可以将传感器的个数以四的倍数增加，处理电路只需增加一个模块。
