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。

The conditional symmetry instability is the intermediate process between the stable and instable states of the atmosphere. The evolution of the atmosphere from the stable to unstable state or from unstable to stable state comes through two stages. The convective-symmetric instability circulation is related with the state and type of the instability. When the conditional instability lies in the lower level and conditional symmetric instability in the upper level, the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level. The release of conditional symmetric instability gives rise to a mesoscale rain belt.

结果表明：条件对称不稳定是大气稳定状态和条件不稳定状态之间的中间纽带，大气由稳定向不稳定或者由不稳定向稳定的演变均通过条件对称不稳定来实现；对流对称不稳定环流的形成与不稳定层的配置有关，当低层为条件不稳定而高层叠加深厚的条件对称不稳定时，对流对称不稳定环流低层出现垂直上升气流，高层出现范围较广的倾斜上升气流，对称不稳定能量释放产生中尺度云带。

When there is statistical difference between training set and test set, robust learning algorithm should be used.

前者认为：当训练语料规模足够大，分布范围足够广时，概率最大的结果是正确的结果。后者认为：在实际训练时，训练语料的规模和范围满足不了参数空间所需求的

Object to, resort to, react to, contribute to, look forward to, be accustomed to, be committed to, be exposed to, be subjected to, be devoted to, be dedicated to, be opposed to, be reconciled to, be contrary to, be used to, come close to, get down to, give oneself up to, prefer…to, see to, set to, take to, in addition to, with regard to, with a view to, on the way to

由于to既可用作介词，也可用作不定式符号，所以许多学生在其后接动词时，弄不清到底该用动词原形，还是用动名词。本文根据新课标词汇(比考试大纲词汇范围稍广)对这类结构作了一次系统归纳，总结出介词to后接动名词的常考结构27个，并根据其结构特点，分为以下四类

But the difference tread electrical engineering to also have some weakness, the most is economically to can't carry out scope more wide smooth adjust soon;Have to absorb the 励 magnetoelectricity of 滞 to flow from the charged barbed wire net, make a charged barbed wire net achievement a type factor to lower.

但是异步电机也有一些缺点，最主要的是不能经济地实现范围较广的平滑调速；必须从电网吸取滞的励磁电流，使电网功类因数降低。

This Palladacycle catalyzed Heck reaction was characterized by a wide variety of substrates, mildness of reaction conditions, freedom from protection of inert gases and high catalytic activity retainable after repeated uses.

二茂铁亚胺环钯化合物催化的Heck反应具有底物范围较广，反应条件温和，不需要惰性气体保护，催化活性高且催化剂可重复使用仍能保持活性的优点。

As for the quantity and scope of the literary quotation used,he has overpassed the writers at that time and grand old mans. As for the state of literary quotation in the poems,they are assimilated by Xin into his own poems,and can hardly distinguish where they are from. As for the motivation of using the literary quotation,Xin is not only for using them,but for building better bourn and expressing the emotion. As for the methods,Xin always use them skillfully to meet different purpose with transfer,direct use and adduction.

稼轩词用典，从数量和广度上说，他广采博收，数量之多，范围之广，远超时贤及前辈；从典故在词中状态而言，浑成脱化，全如己出，同时又雅俗一体，关合无迹，如水中着盐不着痕迹；从用典的目的性而言，稼轩不是为用典而用典，而是为了更好的铸造境界、传达情感；从用典的方法看，稼轩词腾挪变化，根据不同需要或化用或移用或明用或暗用，皆能曲尽其妙。

Unlike other skiing disciplines, which are usually dominated by European athletes, freestyle aerialists cover a wider range.

不同于其他通常由欧洲选手主导赛势的滑雪项目，参与自由式高空技巧比赛的选手涵盖范围更广。

Waterborne diseases are not usually as serious or widespread as water-washed diseases such as skin and eye infections, which result from insufficient water for personal hygiene.

类似皮肤和眼部感染等&水洗病&是由于维持个人卫生的用水不足而引起的。与此相比，&水传播疾病&通常不那么严重，传播范围也不广。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
