早点火

In order to examine the south motorcycle engine preignition phenomenon, using the rich burning information of the massive ions which are produced when the air cylinder is burntThrough analyzing the wave form difference between lighting a fire normally and firing early, it can be determined whether preignition occurs or not.

为了检测南方摩托车发动机早燃现象，利用其气缸内燃烧时产生大量的离子电流信号所包含的丰富燃烧信息，对其火花塞正常点火和炽热点火离子电流显示的波形进行研究分析，从而确定是否发生早燃。

Meantime, through great deal of experiments, spark advance angles, ignition dwell angles, start injection width and electrical throttle threshold were optimally controlled. At last, quick response time of hydrogen-fueled engine was realized, speed stability after successful start was controlled. At the same time, backfire, preignition and fire a gun in the start state of hydrogen fueled engine were avoided.

同时通过大量试验调试，对点火提前角、点火闭合时间、喷气正时、电子节气门开度、起动喷气脉宽进行优化控制，使发动机起动响应时间快，起动后转速波动平稳；同时避免了氢燃料发动机起动时易出现的回火、早燃、放炮等异常燃烧现象。

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。
