Since 1957 Lee's "weak interaction in the parity nonconservation" concept was experimental and that shared the Nobel Prize in Physics; its 1954 proposed standard field theory, in the 1970s developed into integration and understanding elementary particle strong and weak, and electromagnetic interactions of the three foundation are also in the statistical physics, condensed matter physics, quantum field theory, mathematical physics in a number of outstanding major contribution.

著名美籍华裔科学家、物理学大师、诺贝尔物理学奖获得者。1957年由于与李政道提出的&弱相互作用中宇称不守恒&观念被实验证明而共同获得诺贝尔物理学奖；其于1954年提出的规范场理论，则于70年代发展成为统合与了解基本粒子强、弱、电磁等三种相互作用力的基础；此外并曾在统计物理、凝聚态物理、量子场论、数学物理等领域作出多项卓越的重大贡献。

In the buckling question under nonconservation force,a simply example( the dynamic stability question under the uniformly follower forces with small deformation % linear elastic, straight normal.) is considered.The variational equation of braid composite cylindrical shells subjectd to uniformly follower forces is deduced based on the variation principle of quasinatural frequency of elastic nonconservative system self-excited vibration.The calculated formulas of the flutter load and quasinatural frequency of shells are obtained. The program for calculating the flutter load is developed.The numerical example is given and some useful conclusions are obtained.
