The essential problem is expounded as the form - finding analysis of a slack cable - strut system of with comperents loose lengths and under geometrically unstable equilibrium state maintained by its deadweight with given loose lengths of components 根据力密度法的思想，本文提出了一种松弛索杆体系几何非稳定平衡形态的通用找形方法。
The experimental researches are carried out for the improvement of the shape of hd type ' s 70 , 000 deadweight panamax oil tanker , performance of hd propeller and the cooperation among the hull , main engine and propeller 其次，本文通过试验研究的方法，进行了沪东型七万吨级巴拿马油轮的船型研究，沪东型( hd )螺旋桨性能及与船、机的匹配研究。
Similarly , biologists have assumed that the absence of introns from prokaryotes was a consequence of intense competitive pressures in the microbial environment : evolution had pruned away the introns as deadweight 生物学家也以类似的想法，假设原核生物之所以缺乏插入子，是因为微生物处于竞争激烈的环境中的结果：插入子的重担被演化给修剪掉了。
At present , most mobile robots use traditional servo motors as their drivers . this kind of system has a complex mechanism , high price , and a big deadweight . so , it can not need the robocup robot system 目前国内外移动机器人平台通常采用传统的伺服电机作为驱动部件，存在结构复杂，价格昂贵，自重较大等问题，不能很好地满足足球机器人系统的需要。
Government intervention generally leads to a deadweight loss , even if consumer welfare and producer welfare are weighted equally , there will be a net loss from government policies that shifts welfare from one group to the other 政府干预通常会导致净损失，即使消费者和生产者承担相同的福利，也会由于政府的政策将福利由一个组织转移到另一个而产生净亏损。
No back - stays & inclined pylon cable - stayed bridge is a new one . she has very prominent mechanical characters that it substitutes the deadweight of inclined pylon for the back stays force to counteract the girder deadweight of main - span 无背索斜塔斜拉桥结构体系新颖,其最大的受力特点是利用倾斜索塔的自重来平衡主跨主梁上的恒载和活载,而省去了背索及其索力。
2 , when there is no power supply , pulling hand chain could enable the door to rise slowly , pulling deadweight lowering dragline could enable the door to go down at constant speed by deadweight . 3 , the door could be positioned accurately at any location with in the travel 为我公司生产的遥控器和卷门机的配套产品，可在无电的情况下自动实现卷帘门上下，并且在有电的情况下自动充电蓄电。
It expounds as a master hou to exhaustively analyze the ship ' s the operating ratio , shipping ratio , to improve the shipping ratio , to control the speed , and reasonably raise the ship ' s deadweight output coefficient 因为在船舶生产经营过程中有相当大的成本是通过船长的管理而发生的。因此，船舶管理人员应该是既要抓船舶安全生产管理，又要懂得船舶经营，最大限度的控制船舶可交成本。
The analysis of static conditions is carried out for the whole frame of the pipe belt conveyor which is loaded by the deadweight , the working load and static wind load in order to see the adaptability of the whole frame of the belt pipe conveyor for the steady wind condition 对在自重、工作负荷和稳态风场风压共同作用下整体机架结构进行静力工况分析,考查整体机架结构对稳态风场环境的适应性。
