| 1. | 20 st . by eng . due to bad weather / rough sea / fog / poor visibility / sailing in narrow waterway 12点20分由于天气不好/海况差/有雾/能见度差/狭水道航行而待机备车。 |
| 2. | Bow bottom slamming of ship is one of the physical phenomena , which often appears during heavy sea conditions 船首底部砰击是船舶在严重海况中航行时经常发生的一种物理现象。 |
| 3. | Turning test shall be conducted under certain meteorologic conditions and sea condition , the main engine rate of revolution should keep steady 5 - 10 min 迥转试验应在一定的气象条件和海况下进行,主机转速应保持稳定5 - 10分钟。 |
| 4. | There are many factors influencing the placing quality of caisson , such as bed leveling quality , sea conditions , as well as the level of placing equipments 影响沉箱安装质量的因素很多,如基床整平的质量、海况的好坏、安装设备是否先进等。 |
| 5. | In the course of cultivating , the layer of water should be adjusted rationally according to the sea area characteristic , sea state and requisition for illumination of each growth period of kelp 在养殖过程中,根据海区特点、海况变化及海带各个生长期对光照的要求,合理进行水层调整。 |
| 6. | In this analysis procedure , the mean stress is accounted for by obtaining the equivalent stress derived from goodman formula or not and the difference between the two cases are discussed 由于在谱分析方法中考虑到了由波高、特征周期及浪向确定的不同海况,所以本文也分析了各海况对疲劳寿命的影响。 |
| 7. | Test should be proceed under good meteorologic conditions and sea condition , keep the cruise 、 ship speed and main engine revolution of the vessel stable before trial , rudder angle should keep at center position 试验应在良好的气象条件和海况下进行,试验前,应保持航行、航速以及主机转速的稳定,试验期间,舵角应保持在正中位置。 |
| 8. | In the paper , the effects of mooring position , towing line length and towing speed on the course stability and towline tension are analyzed firstly for the ship towing system in calm water 由于在实际海况中,除了受到风、流的影响之外,波浪作用力所造成的影响更为巨大,在波力及波力矩的作用,船只航行的航向稳定性与静水中相去剩甚远。 |
| 9. | But in the real navigation , ship will suffer from the influence of wind , wave and current . furthermore , most of the maritime accidents are often happened in the atrocious weather condition , supported by the hurricane and storm 但是船舶在实际航行中,则要遇到风、浪和流的影响,而且许多海难事故常常发生在恶劣的海况下,往往伴有狂风和暴雨。 |
| 10. | Radar simulator simulates the shipping navigating and collision avoidance under bad visibility by making use of computer emulation technic , in this way students can learn how to make correct decision in complex marine circumstance 航海雷达模拟器利用计算机仿真技术,模拟在能见度不良的情况下船舶的操纵和避碰,使学员应对复杂海况,做出正确的判断。 |
