1·What do you know the bond Angle should be?

你们觉得键角是多少？

2·Polymer stress relaxation process is mainly manifested in the polymer chain segment of the movement and rearrangement, as well as bond Angle changes.

聚合物的应力松弛过程主要表现为高分子链段的运动和重排以及键角的改变。

3·By using two-structure linear combination model, the asymmetric broadening of RDF, the coordination number, the bond Angle distribution and the viscosity of chlorides have also been discussed.

通过两结构模型对径向分布函数非对称展宽、配位数、键角分布和粘度作了讨论。

4·By changing the fixed knife material, adding spacer, repairing the moving knife front and back Angle, transforming the casting bond into double one, the effects were obvious.

通过更换定刀材质，加放垫片，动刀修复前后角，改为双铸带头等后，效果显著。
