The main controller compatible with DS87C550 and P87C552, implements the functions of system resource management and task schedule. The communicatory part, which expands the serial interfaces by TL16C554, implements the communication among the main controller, the remote communication terminal and the field devices. The interface part implements isolation between field devices and monitoring terminal with photoelectric coupling; Solar battery supplies power for the monitoring terminal.

主控部分兼容DS87C550和P87C552两种MCU，实现了系统资源的管理与任务调度；通讯部分采用TL16C554扩展了多个串口，实现了主控部分与远程通信终端及智能仪器之间的通信；接口部分采用光电耦合技术实现了现场设备与监控终端之间的电气隔离；采用太阳能供电技术为监控终端提供了电源。

If you're going solar, you need to know the components.

如果你要去太阳，你需要知道的组件。

The rules include not only the complete procedures to construct the three-powered interpolation used by Shoushi Computus in calculating the solar, lunar and planetary equations of center, but also the detailed routines, namely the Geyuan Shu (the procedure of circle division), to derive the table contained in the Shoushi Computus for transferring the pseudo-ecliptic longitudes of the sun into equatorial coordinates, which turns out to be compatible with the results obtained with spherical trigonometry.

从总体角度来看，他在《授时历》立法原理方面的工作已经超过了嘉靖年间顾应祥和周述学等学者的工作，不过，在弧矢割圆术中应用的高次方程解法方面，邢云路的工作则可能直接受到了顾应祥、周述学等学者相关工作的影响，而且邢云路在高次方程解法方面也没有超出明代历算家对高次方程数值解法的认识水平。

Because a concentrator can be used to improve the energy density in a unit area,it can reduce the dispersion of solar energy.
