Others , who bathe in mysteries professionally , like a quantum mechanists , put physics on a human level by making the observer participate in the existence of the observed 还有些人，专业上陶醉于神秘，例如量子论的机械师，将物理摆在人类的层次，让观察者得以参与被观察者的存在。

Many scientists and mechanists , such as euler , prager , green , ericksen , hill , truesdell , eringen , made great contribution in this field and developed a general theoretical system . however , there still remain a lot that should be further investigated . this thesis discusses the linear theory of field of elastic solids subjected to additional deformation , and the corresponding virtual work equations and the displacement - based variational principle 本文第一章述评了由euler开创的，经prager 、 green 、 ericksen 、 hill 、 truesdell和eringen等学者发展并成功应用的附加变形或运动的思想，作为后续各章的基础。
