1) bisymmetrical cleavage
两侧对称裂;二轴对称裂
2) bilateral symmetrical division
两侧对称分裂
3) bilateral cleavage
两侧对称卵裂
5) axisymmetric fractures emanating from cylindrical holes
孔边轴对称裂纹
1.
Based on the principle of superposition of linear elastic fracture mechanics,this paper derives the approximate analytical expressions of stress intersity factors (KI) at the crack tips of axisymmetric fractures emanating from cylindrical holes with hydraulic fracturing under in -situ stress field and fluid pressure.
本文根据弹性断裂力学的叠加原理,建立了地应力场和流体压力作用下水力压裂中孔边轴对称裂纹尖端应力强度因子K_1的近似解析表达式。
6) symmetrical breaking
对称破裂
1.
Investigating the phase-locking on the torus, we found the regularity of the symmetrical breaking.
观察二环面上的销相运动,发现了系统出现对称破裂的规律,即把双Hopf分叉的两个频率比表示成既约分数的形式,当该分数的分子和分母均为奇效时,网络的吸引子保持对称性,而当分子和分母中任一个为偶数时,就会发生对称破裂。
