电器控制系统与电机是制冷设备中最容易出现问题的部分。本书从最基础的电路知识入手，介绍电冰箱，冷藏柜，窗式空调，汽车制冷，小型冷库等制冷系统的电路原理。...

2D Savitzky-Golay Smoothing Differentiation Filter-2-D Savitzky-Golay (SG) Smoothing and Differentiation Filter. The filter coefficients are calculated from the decomposation property of the 2-D SG filters. In addition, the filter coefficients for mixed partial derivative can be obtained by this function. h=sgsdf_2d3(x,y,nx,ny,d,flag_coupling)x = x data point, e.g.,-3:3 (both odd-length

本实验完成发光二极管的循环点亮实验，由于输入晶振为20M，分频得到count1信号，故每间隔约1S彩灯循环移位一次。 也可以外接32768hz的晶振经4060分频后的1HZclk输入，自己可以尝试改变实验，加以练习。 现象：可以看到流水灯-In this experiment completed the cycle of light-emitting diode light experiments, as a result of the importation of crystal for the 20M, sub-frequency signal received count1, so each interval of about 1S Lantern a cyclic shift. Can also be the external 32768Hz crystal oscillator frequency by 4060 after 1HZclk input, they can try to change the experiment, to practice. Phenomenon: we can see water lights
