Greek playwright Aeschylus probably didn't, but according to the story, he was killed when an eagle or a bearded vulture dropped a tortoise on his bald head after mistaking his noggin for a stone in an attempt to crack open the tortoise's shell.

希腊的剧作家Aeschylus大概就没担心过，但是据传说，他是被鹰或者秃鹫扔下来的乌龟砸死的，因为那只笨鸟把他的光头当成了石头，企图用它来砸开乌龟的硬壳。

Because of this,in the present paper,the emphasis of the work is put on the whole fracture process. Then,two kinds of energy consumption of external force work,namely,elastic strain energy and fracture surface energy at any picked crack propagation are determined using the data obtained from wedge-splitting experiments.

Congenital ptosis is due on the eyelid muscle imperfecta, or disposal of its motor failure caused mostly bilateral, sometimes with Epicanthus, eyes small crack, eyelid narrow, strabismus conditions exist at the same time.

先天性上睑下垂是由于上眼睑内的肌肉发育不全，或支配它的运动神经不全引起的，多为双侧，有时可与内眦赘皮、眼裂小、眼睑狭窄、斜视等情况同时存在。

Element-free Galerkin Method is a effective method for solving partial differential equations with the help of shape functions coming from moving least squares approximation. It is well-suited to problems involving large deformation and crack propagation etc on which Finite Element Method can not be used easily. But EFGM is computationally expensive and it is hard to impose the essential boundary condition. Coupling the EFGM and FEM can fetch up the defect of EFGM and improve the efficiency highly.

无网格伽辽金法是基于移动最小二乘法的一种用来求解偏微分方程非常有效的方法，在处理诸如高度大变形、裂纹动态扩展等有限元法较难解决的问题时有其独特的优势，但是存在处理边界条件复杂，计算量大的不足，将无网格法同有限元耦合可以解决这些缺点，极大的提高计算效率。
