angle strain是由于分子中某相邻键的角度与该类正常键的键角相差很大引起的.例如环丙烷C-C-C的夹角为60度,这与饱和烃中C-C-Csp3键角109.5度相差很大,所以不稳定.一般说成,由于存在angle strain,因此环丙烷有开环的倾...结果一 题目 angle strain,torsional strain和steric strain之间有什么区别呀? 答案 angle...
angle strain是由于分子中某相邻键的角度与该类正常键的键角相差很大引起的。例如环丙烷C-C-C的夹角为60度，这与饱和烃中C-C-Csp3键角109.5度相差很大，所以不稳定。一般说成，由于存在angle strain，因此环丙烷有开环的倾向，易于开环来释放angle strain.torsional strain是由于重叠式构象带来的空间...

The shear modulus and the polar moment of inertia represent the material's reluctance to twist or suffer a shear strain (in fact, shear strain is related to ϕϕ through the shear strain equation). While the shear modulus is a material property, the polar moment is a geometric property ...
Describe how stress and strain relate to elastic deformation? Give a definition of the following term: Torque. Explain why the expression E^2 - p^2c^2 is a relativistic invariant (that is, it has the same value in a...
