二冲程循环

"In a two-stroke cycle, the compression and power strokes of the four-stroke cycle are carried out without the inlet and exhaust strokes, in one upstroke and one downstroke of the piston and one revolution of the crankshaft."

在二冲程循环中，只有四冲程循环的压缩和动力冲程，而没有进气和排气冲程，在活塞的一个上升冲程、一个下降冲程，同时曲轴旋转一周后完成。

An alternative cycle is the two-stroke cycle, which combines the exhaust and compression strokes into one.

另外一种循环方式是二冲程循环，这种循环把排气冲程与压缩冲程结合成一个冲程。

In October, 1883, he established "the benzene tribuluscompany and the Lai 茵 coal gas engine plant", in 1885 he has madethe first benzene tribulus patent vehicle at Mannheim, this vehicle isa three-wheeled automobile, uses a two strokes simplexes 0.9horsepower gasoline engine, this vehicle has had modern automobilesome essential features, like the spark ignition, the water coolingcirculation, the steel pipe frame, the spring 悬架, the rear wheeldrive front wheel changes and applies the brake the handle and so on.

苯茨，首次试验成功一台二冲程试验性发动机。1883年10月，他创立了&苯茨公司和莱茵煤气发动机厂&，1885年他在曼海姆制成了第一辆苯茨专利机动车，该车为三轮汽车，采用一台两冲程单缸0.9马力的汽油机，此车具备了现代汽车的一些基本特点，如火花点火、水冷循环、钢管车架、钢板弹簧悬架、后轮驱动前轮转向和制动手把等。

"In a two- stroke cycle, the compression and power stroke s of the four- stroke cycle are carried out without the inlet and exhaust stroke s, in one up stroke and one down stroke of the piston and one revolution of the crankshaft."

在二冲程循环中，只有四冲程循环的压缩和动力冲程，而没有进气和排气冲程，在活塞的一个上升冲程、一个下降冲程，同时曲轴旋转一周后完成。

MWM engine makes the conversion among two-stroke mode, four-stroke mode and six-stroke mode of one engine come true in theory, filles in the blank with 1/3 which is the ratio of total strokes to working strokes in single working cycle of engine, possessing the continuous variable compression ratio of a certain range at the same time, combines the advantages of two-stroke engine and four-stroke engine, expandes the working range of engine greatly.

MWM发动机在理论上实现了一台发动机在二冲程、四冲程与六冲程工作模式之间的相互转换，填补了发动机单工作循环作功行程数与总行程数比值中1/3的空白，同时具备一定范围连续可变的压缩比，整合了二冲程与四冲程发动机的优点，拓展了发动机的工作范围。

"The size, weight, and cost of the engine per horsepower are therefore less, and two-stroke-cycle engines are used in motorcycle s and smaller machines (e.g., lawnmowers and power rakes)."

因此，每马力所要求的机器尺寸、重量和价格成本也就降低了，所以二冲程循环发动机多用于摩托车和小型机器。

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。
