烧坏的

By example analysis and experiment result compare,it introduces the usage and peculiarity of Multisim 2001 software platform of EDA technology in design type of experiment study on digital circuits,the advantages and disadvantages of EDA technology experimenthave been compared with actual operation,the important of combining"imitation experiment"and"material experiment"in design type of experiment of digit circuit teaching is put forward in this paper.

目前，国内高校的数字电路实验教学模式主要以2种方式进行：一种是完全采用常规的TTL逻辑器件(如逻辑门、触发器等中小规模集成电路)进行硬件连线测试，大多采用面包板或由多个双列直插座组成的各种实验箱。这种方式容易出现器件接触不良，接线不慎而烧坏芯片、电源等故障，学生实验课时得不到有效利用，影响对学生综合设计性实验能力的培养与提高。

The heating of the core may damage the interlamination insulation, increasing iron loss if the burn- out temperature is too high.

Leave night , not a sound from the pavement has the moon lost her memory she is smiling alone in the lamplight the withered leaves collect at my feet and the wind begins to moan memory, all alone in the moonlight i can smile at the old days life was beautiful then i remember the time i knew what happiness was let the memory live again every street lamp seems to beat a fatalistic warning someone mutters and the street lamp sputters and soon it will be morning daylight i must wait for the sunrise i must think of a new life and i mustn't give in when the dawn comes tonight will be a memory too and a new day will begin burnt out ends of smoky days the stale court smell of morning a street lamp dies another night is over another day is dawning touch me, it is so easy to leave me all alone with the memory of my days in the sun if you'll touch me, you'll understand what happiness is look, a new day has begun...

离开晚上，没有一个健全的路面已经失去了在月球记忆她面带微笑独自在灯光收集的枯萎叶片在我的脚下和风力开始呻吟记忆，独自在月光下我可以微笑古早生活是那么美好我记得当时我知道什么是幸福让生活再次记忆每个路灯似乎击败宿命预警有人悄悄地和路灯sputters 不久，这将是今天上午白天我必须等待日出我必须想出一个新的生命，我绝不能放弃的当黎明来今晚将是一个记忆太和新的一天开始烧坏两端黑烟天法院的陈腐气味上午街道灯模具一个晚上结束另一天的曙光碰我，是很容易离开我所有单独的内存我的天在太阳底下如果您要碰我，你就会明白什么是幸福你看，新的一天已经开始。。。

The assembly of journal and plain bearing liner space is too little, force of organic still oil pressure is small it is the crucial index that affects lubricant result, make lubricate because of lacking engine oil between crankshaft and plain bearing liner and bite dead invalidation, include to be pulled badly, lack lube, layer of alloy of dry attrition generation is fused, grind sliding surface to did not maintain the oily film of certain ply, and all sorts of local overload exhaustion are destroyed, cavitation erosion and V form are destroyed etc, through technology of him director diesel locomotive old experience reachs the analysis of pair of its breakdown reasons, put forward precautionary measures especially. As a result of,the burns caustic mechanism plain bearing liner to burn caustic mechanism of 1 plain bearing liner is the lube film burst between journal and plain bearing liner, cause plain bearing liner and crankshaft generation clash, below high temperature, high pressure and high rotate speed, the wear-resisting alloy layer of plain bearing liner wears away prematurely or fuse, cause plain bearing liner and crankshaft to stick thereby bite, can make the steel back of plain bearing liner and Kong Zhong produces whirligig, inlet port is jammed, carry on the back by steel again with the friction of aperture causes high temperature to make plain bearing liner burned-out further, can cause bolt to break off, happen swing a malign accident that pounds cylinder body of bad internal-combustion engine.

轴颈和轴瓦的装配间隙太小，还有机油压力低是影响润滑效果的关键指标，使得曲轴和轴瓦之间因缺少机油润滑而咬死失效，包括严重拉伤，缺少润滑油，干摩擦产生合金层熔化，磨滑面没有保持一定厚度的油膜，以及各种局部过载疲惫破坏，气蚀和V形破坏等，通过本人主管内燃机车技术多年经验及对其故障原因的分析，特提出预防办法。1轴瓦的烧损机理轴瓦烧损的机理是由于轴颈和轴瓦之间的润滑油膜破裂，导致轴瓦和曲轴产生摩擦，在高温、高压和高转速下，轴瓦的耐磨合金层过早地磨损或熔化，从而引起轴瓦和曲轴粘咬，会使轴瓦的钢背和座孔中产生旋转运动，进油孔被堵塞，再由钢背和座孔的磨擦进一步引起高温使轴瓦烧坏，并会造成螺栓折断，发生甩出捣坏内燃机缸体的恶性事故。

This and other methanol-based kickers are sometimes fatal: 10ml of methanol can burn the optic nerve; 30ml can kill.

这种酒和其他甲醇勾兑的烈酒有时候是致命的：10ml的甲醇即可烧坏视神经、30ml即可致命。

Fourth, to avoid breaking material: Screw must not be allowed in the case of blanking operation, upon occurrence of the stator as dry friction of rubber, produces instant heat and burn, so good grinder, screw grille flow is a necessary condition for normal operation To this end, some screw pump body is also expected to stop off device installed, when there Fracture, because he has a self-priming screw pump function of the characteristics Chemical pumps of the body will produce a vacuum chamber, vacuum screw pump will stop operation.

四、避免断料：螺杆泵决不允许在断料的情形下运转，一经消防泵发生，橡胶定子由于干摩擦，瞬间产生高温而烧坏，所以，粉碎机完好，格栅畅通是螺杆泵正常运转的必要条件之一，为此，有些螺杆泵还在泵身上安装了断料停机装置，当发生断料时，由于螺杆泵其有自吸功能的特性，腔体内会产生真空，真空装置会使螺杆泵停止运转。

Screw must not be allowed to break at the expected operating circumstances, once happened, rubber stator do because of friction heat generated instantly burned, so, good grinder, screw grille flow are a necessary condition for the normal operation of one of For this reason, some screw pump was also installed devices break down material, when the expected happened when broken, because of the screw pump has self-priming function of its characteristics, the body will produce a vacuum chamber, vacuum devices will stop screw operation.
