一个二维静电场，电位函数为φ（x, y），将正方形分成25个正方形网格。有16个内部网格点。假定16个网格点的初值都定为零，试用超松弛法确定16个内部网格点的电位值。(A two dimensional electrostatic field, the potential function for phi (x, y), the square into 25 square grid. There are 16 internal grid point. Assume that 16 mesh point of initial value at zero, trial overrelaxation method to determine the potential value of 16 internal grid point.)

HART协议文本，很难找到的，对开发HART协议相关特别有用。(HART text of the agreement, it is difficult to find, on the development of HART protocol related particularly useful.)

An inductive feedback technique increases the speed of resonant circuits by 62 , allowing operation near the of transistors. The technique leads to a fundamental oscillator operating at 128 GHz with a power dissipation of 9 mW and a phase noise of 105 dBc/Hz at 10-MHz offset. A divide-by-two circuit based on the idea and incorporating a sampling mixer achieves a maximum speed of 125 GHz while consuming 10.5 mW. The prototypes have been fabricated in 90-nm CMOS technology.(An inductive feedback technique increases the speed of resonant circuits by 62 , allowing operation near the of transistors.
