In these artworks, illusive emotions with personal and interesting tones appear natural and casual. The selection of materials has become an attitude. Styles and forms have become the carrier of attitudes. Feelings and experiences are expressed without interpretation. It appropriates and uses, without any moral judge, any claim or any answer for any question. Willfully, subjectively and unfaithfully copying the world, art has an unprecedented lack of need to claim its rightfulness, or to force its audience to understand that the work is about. It even intentionally returns to a kind of naivety. The works seem to be excreted rather than constructed. These are all prominent features of postmodernist creations in a social situation that beholds neoliberalism as the mainstream ideology.

幻觉式的情感、富于个人性和趣味性的语调，不动生色地刻意雕琢却以最平淡随意的形式出现，对材料的选择作为一种态度，风格和形式也成为态度的载体，不需要被阐释只需要被感知、体验、欣赏和使用，不做任何道德判断，不发表任何声明，或对某个问题做出一个答案，肆意地、主观地、不忠实地去复制世界，艺术前所未有地不需要去证明自己的正当性，也不要求人们去探问艺术作品在说什么，甚至有意地回归到一种天真的状态，作品似乎是被分泌出来的，而不是被构造出来的，这些都是在以新自由主义为主流意识形态的社会形势中后现代主义作品的最显著的特点。

Furthermore, the computational results indicate that the surface displacement fields varies with the distance form the fault, and the vertical displacement fields show strong inhomogeneity, in which largen displacement focuses on the ends of fault.
