It includes as follows:(1) That the right acceptance probability to decide the initial value temperature should be 0.6 are presented by experiment. For the first time, crossover and mutation operator are used in populations to calculate the initial value of temperature. At least the initial value of temperature is 〓.(2) Replacing random change operator with crossover and mutation operators.

2使用遗传算法中交配与突变代替模拟退火算法中随机扰动操作，对两种操作方法进行定性分析，得到突变和交配操作与随机扰动方法在本质上的一致性；同时首次提出在不同温度条件下，使用不同的比例因子，控制参与交配与突变的基因位数，实现了二次使用模拟退火算法的过程。

So far, many genes have been found to be related to this disease, such as TGFA,TGFβ3, BCL3, F13A, etc. The role of the environment in modulating genetic effects is equally critical and three major classes of environment triggers have been studied, including teratogens(e.g. tobaccos, ethanol, glucocorticoid, et al), infection and innutrition.

常见的引起唇腭裂相关的基因有TGFA，TGFβ3， BCL3， F13A等；环境因素在唇腭裂发生中的遗传修饰作用也很重要，主要的环境激发因素包括致畸因子（如烟草、酒精、糖皮质激素等）、感染和营养缺乏。
