By means of the sea trial , it is verified that at full loading condition of 12 . 5m draught , the vessel ' s speed attained to 15 . 09 knots with the rotate speed of 100 . 5rpm , at the condition of the sea margin of 15 % and rotate speed margin of 5 % at csr of main engine Sin ) ,主机正常功率带有15的海上裕度和5转速裕度时,航速为15刀9节,转速100 5pm ,与设计吻合。最后,本文进行了沪东型( hd )螺旋桨的系列研究。
In the end we have made a 50v / 10a full - bridge pwm dc / dc converters based on an improved circuit topology of full bridge phase shift zvs pwm converter . it can achieve zvs from no load to full load in virtue of an assistant commutation inductor 最后,构造了一个改进的全桥移相zvsdc dc变换器拓扑,在此基础上研制了50v 10a通讯用全桥移相开关电源,该电源借助于辅助换流电感,在空载到额定负载范围内均可实现zvs 。
Thirdly , this paper has a research on some optimization algorithm , such as : general vsp model , vsp model with time window , c - w saving heuristic algorithm , general ga , ga with soft and hard time window and full load vehicle algorithm model 第三,论文论述了运输路线的几种优化算法,包括一般vsp模型,有时间窗的vsp模型, c - w节约启发式算法,一般遗传算法以及可同时处理软、硬时间窗的遗传算法和满载车辆算法模型。
In the full load range , the engine exhaust contains no smoke and the nox exhaust obviously decreases and the engine noise also decreases . the different fuel blends consisting of predorminant dme and some diesel can conqer or in large part improve the wear and leakage of plunger 二甲醚和柴油混合燃料除了有较好的动力性、经济性和排放指标外,由于粘度增加可以克服或在很大程度上改太原理工大学硕士学位论文善油泵、油嘴的磨损、泄漏问题,具有使用价值。
