The results show that the asymmetricdistribution of orography and that of horizontal diffusion coefficients are likely to be the causes leading to the asymmetric motion.
结果表明：非对称的地形分布和水平扩散系数的分布可能是导致非对称运动的原因。

That is the torsion effect under bi-directional earthquake action on the structure with remarkably uneven and asymmetricdistribution of mass and stiffness should be considered.
Symmetric algorithms have faster performance than asymmetric algorithms, but passing the secret key securely between participants poses a distribution problem.
