The system adopted active tracking,namely calculate the input angle of the tracking device in advance,the angle is correspondent to the sun position some moment.Photoelectric sensors react the sunlight that putting on different position of the platform, feedback electrical signal.Then single-chip applys the subprogram and sends out pulse to step motors according to the signals,can control the rotate angle and direction of the step motor. The mechanism has realized the automatic track to the sun, so that the trackers top flat board can be always vertical to the sunlight and arrive the furthest receiving energy.

系统采用主动式跟踪，即预先计算好对应于某时刻太阳位置的跟踪机构的输入角度，通过跟踪器上平台不同位置上摆放的光电传感器感受该太阳位置的光照，反馈回电信号，单片机根据该信号调用子程序发出脉冲对步进电动机的转动角度和方向进行控制，实现了机构对太阳的自动跟踪，使跟踪装置的上平台始终处于垂直于光照方向，达到了能量最大限度的接收。

If a flat solar panel is mounted on level ground, it is obvious that over the course of the day the sunlight will have an angle of incidence close to 90°in the morning and the evening.

如果一个单位的太阳能电池板将被安装在水平地面，很显然，在这一天，阳光将有入射角接近90 °在早上和晚上。

Note that the signal amplitude is nominally flat, despite the varying range and angle of incidence associated with scanning.

波的轮廓以中心对称这个PPS系统的特征是扫描过程使接收能量在接受器表面移动的结果。

Because the increasing of dip angle can lead to special strata behavior which cause difficulties to mining, The strata behavior theory can not be simpely borrowed from that of flat and gently inclined seams. In order to cut down roof accidents and increase production efficiency, the strata movement and stress distribution must be reassessed for seam with deep dip angle.

煤层倾角增大带来了矿压显现的特殊性和开采上的困难，不能再简单地借用水平和缓倾斜煤层的矿压理论，而必须对大倾角煤层围岩运动与应力分布予以重新评价，以降低顶板事故，提高生产效率。

Whether it was a flat ball down the line or a heavy topspin angle shot, I was able to go after each shot with confidence because of the control I was getting.

无论是要打出平击的底线球还是强烈旋转的大角度的回球，我都能自信的击出，因为它的控制是如此的惊人。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
