拖拉的

Researches show that the drive force characteristics of the electric tractor drive system based on series DC motor is close the ideal characteristics, the curves are concave, low speed with constant power, and high speed with constant torque; the electric tractor has large working speed under different shifts, but the extensive coincidence speed shows that the variable ratio of the gear is unreasonable; the maximum climbable gradient of this electric tractor is more than 30%, and does not need frequent shift when working for its extensive climbable gradient; there are many influence factors of continuous working time, which the more obvious factors are working speed and working load, the working time increases with the increase of the working speed and working load.2. Simulation researches on the drive characteristic of the electric tractor.

研究结果表明：基于串励直流电动机(来源：ABC21论文网www.abclunwen.com)的电动拖拉机电驱动系统的驱动力特性场接近理想驱动力特性场，其各挡下的驱动力特性是一组下凹的曲线，低速恒转矩，高速恒功率；同一行驶速度下所对应高挡驱动力大于低挡驱动力，这是由电机的调速特性决定的；电动拖拉机各个挡位下具有较广的稳定作业速度范围，但是各个挡位之间速度重合的范围较多，说明所用变速箱变速比与电动机匹配不合理；电动拖拉机最大爬坡度达到30%以上，并且各挡爬坡度变化范围较广，作业过程中不需要频繁换挡；影响电动拖拉机连续作业时间的因素较多，其中作业行驶速度和作业负荷影响最为明显，作业负荷越大，连续作业时间就越短，作业速度越快，连续作业时间就越短。2、电动拖拉机驱动特性仿真研究。

He struck at the projecting part of his helmet and drove the spear into his brow; the point of bronze pierced the bone, and darkness veiled his eyes; headlong as a tower he fell amid the press of the fight, and as he dropped King Elephenor, son of Chalcodon and captain of the proud Abantes began dragging him out of reach of the darts that were falling around him, in haste to strip him of his armour.

他首先投枪，击中插顶马鬃的头盔，坚挺的突角，铜尖扎进厄开波洛斯的前额，深咬进去，捣碎头骨，浓黑的迷雾蒙住了他的眼睛。他栽倒在地，死于激战之中，像一堵翻塌的墙基。他猝然倒地，强有力的厄勒菲诺耳，卡尔科冬之子，心胸豪壮的阿邦忒斯人的首领，抓起他的双脚，把他从枪林矛雨中拖拉出来，试图以最快的速度

The weakest aspect is the draggy comic interplay between Xia and Zhe, with Du especially grating as the handsome Xia's doofus sidekick.

影片最弱的地方是Xia 和 Zhe 的拖拉冗长的喜剧对手戏，特别是Du，简直是英俊的 Xia 的蠢伙伴

Nomological Network Associated With Active Procrastination 3,Despite Bui's call for additional empirical studies on active procrastination, in the current literature, researchers now simply acknowledge the presence of an adaptive type of procrastinator in interpreting their findings , perhaps because of the nascent developmental stage of this construct and lack of empirical research using active procrastination as a measured variable.

2： 法则网络相关的有源拖延。 3：尽管裴对拖延的积极呼吁更多的实证研究，在目前的文献，研究人员现在只要承认一个拖拉在解释他们的调查结果自适应类型的存在，也许是因为这个新生的构造和使用积极的实证研究缺乏发展阶段拖延作为衡量变量。

He was merely serving up the same old reassuring myth, so carefully sustained from generation to generation, of a happy bucolic world untouched by the conflicts and savageries of real life, one more episode in the long-running story of Arcadian shepherds and Bourbon milkmaids, of Soviet tractor drivers and Merrie England.

他只不过是将一个同样是老掉牙的神话搬出来给人压惊罢了。这个神话好不容易熬过了一代又一代：快乐的田园生活里，了无纷扰、残酷的现实生活痕迹，是阿卡迪亚牧羊和波旁挤奶姑娘故事的又一章节，是苏维埃拖拉机手和Merrie England的神话。

In order to meet the testing requirmets in paddy field, the author proposed a new slippage control mechanism added to the tractors which are in mass production, the author also explicated the new method principles and its advantages, and a testing track-laying chassis has been rebuild according to this new method.

在对已有的滑转率控制机构分析的基础上，为满足水田中试验的需要，提出在成批生产的拖拉机上加装滑转率控制机构的新方案，论述了这种方案的原理，说明了它的优点。

There is no obvious reason why the clusters should be moving at such breakneck speeds, unless they are experiencing an unusually strong pull from something beyond the visible horizon.

至今还没有找到明显的理由可以说明这些星系群为什么竟会以这种极快的速度来运动，除非它们正在受到某些不在我们可见视域内的物体的异常强大的引力的拖拉。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
