The contracting parties shall conduct cooperation to crack down on illegal immigration, including the crack down on illegal transportation of natural persons via its territory.
缔约双方将合作打击非法移民，包括打击通过本国领土非法运送自然人的行为。

The natural frequencies of beam are calculated with finite element method in the cases of different crack width and different crack depth.
本文利用有限元法分别计算在不同的裂纹深度、不同的裂纹开口宽度的情况下梁的固有频率。

The results show that the fatigue crack not only decreases the natural frequency, but also causes non linear vibration.
