 In this article we discuss the design of doublecrystal monochromator control system of 3B3 middleenergy beam line in Beijing Synchrotron Radiation Factory. The multimedia timer and multithread technique were used to solve the high speed data transmission in serial port system and data communication in multiserial port system. The real time graph drawing and dynamic zooming in doublecrystal monochromator debugging system accomplished by VC++6.0 were also described.  讨论了北京同步辐射装置(BSRF)3B3 中能光束线双晶单色器控制系统的设计。采用多媒体定时器以及多线程技术,实现高速下数据在串口系统中的传输以及多串口数据通讯问题。在双晶单色器调试系统中,在 VC++6.0 中实现图形图像的实时绘制和动态缩放。  A new planar graph planar orthogonal straightline drawing algorithm is proposed which is based on genetic algorithm.

A new planar graph planar orthogonal straightline drawing algorithm is proposed which is based on genetic algorithm. The algorithm transforms the problem of planar graph drawing to that of constraint optimization, and constructs a function with constraints according to the aesthetic criteria of graph drawing problem, and then uses genetic algorithms to find approximate optimal solutions to the objective function, and thus obtains a planar orthogonal straightline drawing of the planar graph. The new algorithm is of following advantages: the method is simple and it is easier to be implemented and also the figure drawn is beautiful, finally, the algorithm is stable. The experiment results show that the final results of the drawing algorithm don't rely on the initial status of graphs.  提出了一种基于遗传算法的新的平面图平面正交直线画图算法,算法将平面图画图问题转化为约束优化问题,根据画图问题选定的美观准则构造约束函数,用遗传算法求解目标函数的最优解的近似值,从而得到平面图的平面正交直线画法。新算法的优点是方法简单,易于实现,画出的图形美观,算法稳定性好。实验结果表明,画图算法的最终结果不依赖于图的初始状态。  The digitization for engineering record curves is very important for the digital storage, reuse, share and exchange of these curves.
