Because among this thesis focal point to realize genetic algorithms, arrange in concrete while realizing class, not adopting the genetic algorithm, so the problem solved mainly in this thesis is how to utilize the genetic algorithm to solve the time interval of optimizing.
由于在本论文中重点是实现遗传算法，而排班在具体实现时，没有采用遗传算法，故在本论文中主要解决的问题是如何利用遗传算法解决优化发车间隔问题。
Focal photocoagulation is completed in 2 or 3 times and panretinal photocoagulation is completed in 4 or 6 times. The interval of laser photocoagulation is 1 or 2 weeks.
根据病情的不同，激光光凝治疗的次数不等，一般局部光凝2～3次完成，全视网膜光凝4～6次完成，光凝时间间隔1～2周。
When the distance between positive and inverse Fourier transform system changes, the CCD is adjusted to the focal plane by variable value of interval between two peaks on CCD with computer.
通过镜组移动改变正、负傅里叶变换系统的距离，用软件比较CCD上两个波峰的间隔是否变化来对CCD进行定焦。
