At the same time , the provided sequence optimal method and the methode which changes coordinate are also presented , the provided sequence optimal methode is a way which turns nonlinar problem to linar problem and the basic train of thought and maths deduction are discussed in detail ; the methode which changes coordinate is a way which simplfied a many dimensions problem to many problems of one dimension , and the advantage of this method is clear concept , easy to understand and creat procedure 文中还介绍了序列优化法和坐标轮换法。序列优化法是一种化非线性问题为线性问题的一种方法，论文详细地论述了这种方法的基本思路及数学推导；坐标轮换法是一种将一多维问题简化为多个一维问题的优化方法，这种方法的优点是概念清晰，浅显易懂，便于软件实现。
