air inflow

The air inflow in each circle is basically constant, while the diesel engine is working. So each working condition is adjusted to change the output power, by means of changing the oil injection ( changing the density of the gas mixture).

柴油发动机工作时每个循环的空气进气量基本上都是恒定的，要改变输出功率，只有通过改变喷油量（即改变混合气的浓度）来调节各个工况。

In 1-D experiment, we found that without controlling the air outflow the water inflow rate was reduced compared with the water inflow rate under the condition, as observed by other researchers.

在一维入渗实验中，我们发现在控制气体出流的情况下水的入渗速率比在没有控制的情况下有所减少。

The reasons of air inflow less than water outflow are hysteresis phenomenon exiting in unsaturated flow, and air expands and diffuses as soon as it entering sand.

造成进气流量小于出水流量的原因主要是在非饱和流中存在滞后现象和进入砂层后的空气体积膨胀和扩散。
