Based on the laminate theory, a laminate weakened by damage is treated as an anisotropic thin plate. Using the complex potential method in the plane theory of elasticity of an anisotropic body, the series solution of finite anisotropic thin plate containing an elliptical inclusion is proposed with the help of Faber series. A hybrid element with an elliptical inclusion for anisotropic materials is obtained by using the hybrid variable principle, and the element efficiency is verified by numerical examples. The state of the damage is modeled by an elliptical soft inclusion, and using the point stress criterion based on characteristic curve and Yamada-Sun etc. criteria, the prediction of the strength of a composite laminate with damage is set up. The effects of various parameters on the stress distribution and the residual strength of a composite laminate weakened by damage are detailedly studied.

So the legislative ideas must focus on the control of human behavior, but more important, the need for anti-desertification is to introduce the idea of coordination of human and land.

因此相应的立法理念、思路和重点就必须重在对于人的行为进行控制，需要治沙但更为重要的是在立法中引入人地协调的理念。

After the outbreak of Anti-Japanese War, chairman Lin Sen ordered to move the capital from Nanjing to Chongqing on November 20, 1937, and all the staff arrived in Chongqing the same year. On December 9, 1941, Lin Sen, on behalf of the nationalist government, declared war against Japan, thus China's Anti- Japanese War was a part of the world anti-fascism battle. Lin Sen died of a road accident and its complications on August 1, 1949. He was buried beside his official residence—"Lin Yuan"(which is located in the PLA Chongqing Communication College).

抗日战争爆发后，1937年11月20日，他以国民政府主席身份在南京颁发了"正式迁都重庆"的命令，同年11月亲率机关工作人员抵达重庆。1941年12月9日，林森代表国民政府正式宣布对日宣战，并宣布对德、意两国处于战争状态，从而将中国的抗日战争引入了世界反法西斯战争范畴。1949年5月10日，林森因车祸引发脑溢血，由于年势已高，加之战时医疗条件欠缺，久治不愈，于同年8月1日去逝，葬于其山洞蒋介石送给他的官邸旁（在今解放军重庆通信学院内），世称"林园"。
