查询词典 ballast engine

The author mainly introduces the test devices for high-voltage pulse of ignitor, testing devices for pulse of ballests for lamps with overall activating devices and testing devices for the partial rectification of pulse of electronic ballast for fluorescent lamps, for reference.

由于一些照明电器检测装置使用上的不广泛性和功能上的特殊性，所以往往没有现成的装置可买，并且有些看似简单的东西确隐含着较高的技术难点。下面介绍几种已试制成功并能可靠使用的且能满足 IEC 标准和国标的检测装置，供业内同行们共享。

The author mainly introduces the test devices for high-voltage pulse of ignitor, testing devices for pulse of ballests for lamps with overall activating devices and testing devices for the partial rectification of pulse of electronic ballast for fluorescent lamps, for reference.

作者重点介绍了触发器高压脉冲检测装置、带整体式启动装置的灯用的镇流器脉冲试验装置及荧光灯电子镇流器局部整流效应检测装置，供业内人士参考。

The mittened mini-monster was first recorded in Britain in the Thames in 1935 having almost certainly arrived as larvae in the ballast water of ships from the Far East.

据记载，英国1935年最早在泰晤士河发现这种&戴着拳击手套&的小怪物，它们十有八九是幼体时期随着远东船只的压舱水来到这里的。

A certain amount of care,or pain or trouble is necessary for every man all the times .a ship without ballast is unsatable and will not go straight.

一定的忧愁、痛苦或烦恼对每个人都是时时必需的。一艘如果没有压舱物，便不会稳定不能朝着目的地一直前进

Trial speed on ballast draught without PTO connected and 100 % MCR will be approx.

在压载状态，不带轴带发电机，100%MCR 时试航速度大约为17.5 节。

From there, the idea was simplicity itself: Attach a garden-variety, Sears aluminum lawn chair to the balloons, strap on some water jugs for ballast, take along a pellet pistol to shoot out the balloons to control the descent, pack a parachute and carry a CB radio, and maybe, with luck, sail across the desert to the Rocky Mountains.

有了这些，想法就变得非常简单了：在一把普通的、Sears牌的铝制草坪椅上绑上气球，系上些水壶来压舱，带一把气手枪用来打气球、控制降落，装好一只降落伞，带上一个民用波段无线电，运气好的话，有可能飞跃沙漠，抵达落基山脉。

A new ballast tank allows you to fill and empty water in minutes at the touch of a button.

一种新的压载水舱可以填写并在一键在几分钟内空水。

The support framework is ballasted with any convenient material to counterbalance the load; in a development, one or more containers of water are used as ballast.

Wheel/rail noise of the high-speed slab track on concrete bridge and that of the urban elevated supporting block track are predicted respectively. Noise of the slab track, compared with that of the ballasted track, is more severe. The noise of the slab track is about 6.2dBA higher than that of the ballasted track for the receiver nearby the rail, and about 3.5dBA higher than that of ballast track for the receiver

对降低高速铁路桥上板式无碴轨道及城市轨道交通桥上支承块式无碴轨道轮轨噪声的技术措施进行了研究，包括：(1)分别就板式轨道和支承块式轨道结构参数的低噪声设计原则进行了研究；(2)对几种典型的新型轨道用吸声材料的降噪效果进行了分析，结果表明降噪效果显著；(3)就声屏障高度、位置、形状以及声屏障内侧敷设吸声材料对降噪效果的影响进行了分析，结果表明：声屏障越高、越接近轨道，降噪效果越好；声屏障内侧敷设吸声材料，可降低钢轨近旁噪声2.0～3.0dBA，可降低近地面噪声约1.5～2.0dBA

For fixture models that may use different ballasts either in terms of the type of ballast or manufacturer
