中文摘要：

残余应力大的薄膜，容易产生脱膜现象，使得薄膜失去所需功能。在激光薄膜领域，残余应力也是薄膜激光损伤阈值难以提高的原因之一。基于热收缩效应模型和弹性力学原理，从薄膜膜系着手提出了控制薄膜残余热应力的膜系设计原则，将该原则的评价函数用于薄膜膜系设计中，采用优化方法可以设计出残余热应力可接受的薄膜。

英文摘要：

The high residual stress in thin films tends to decoating, thus causing the films to lose the functions the films should keep on. For the the laser-deposited films, the residual stress in films make them difficult to raise the threshold value above which the films will be damaged due to ldser irradiation. Based on the pyrocondensation model and principles of elasticity, the layer structure design of thin films was proposed in view of the control of residual thermal stress and the corresponding evaluation function was applied to the layer structure design of films. As a result, the films in which the residual thermal stress is acceptable are designed via optimization.
