涡流

For the problem in these two methods,the blade element is divided by using weight number in first method and the influence by trailing vortex is considered correspondingly.As a result, the wind wheel model is more reasonable and accurate.

针对以上两种方法建模时遇到的问题，在前一种方法中运用权系数来分隔桨叶的叶素，而后一种方法充分考虑了尾涡流效应的影响，更加合理和精确的建立的气动模型。3。

The study site is located at Wung-Fong Agricultural Research Institute where the interference caused by buildings which affect the wind direction to Eddy Covariance System can be reduced to the minimum. The measurement was made from 28th April to 5th June in 2009 through automated measurement and data logging system.

本研究场址为台中县雾峰农业试验所中的水稻田，由於附近并无太多的建筑物干扰风的行进，可对於干扰涡流协变性系统的因素减低到最少，实验观测期间为2009年4月28日至2009年6月5日止，实际实验天数约25天。

Breakers impact the working principle: stone from the machines directly into the upper part of the high-speed rotary dial, in the role of high-speed centrifugal force, and another part of the umbrella-type approach to divert around the target in the dial-a high-speed collision with high-density Smash, stone in the fight against each other, the Wheel and the case will be formed between the eddy current campaign against each other many times, friction, grinding, through discharge from the bottom.

冲击式破碎机的工作原理：石料由机器上部直接落入高速旋转的转盘，在高速离心力的作用下，与另一部分以伞型方式分流在转盘四周的靶石产生高速度的撞击与高密度的粉碎，石料在互相打击后，又会在转盘和机壳之间形成涡流运动而造成多次的互相打击、磨擦、粉碎，从下部直通排出。
