The feature of comprehension is based upon students, attempting to carry forward the spirit of main body of students in linguistic sense teaching. Feature of entireness is from the angle of literary works, demanding that the linguistic sense teaching is based on the macro-examination and systematic mastery of the entire modern essays. Feature of construction concerns the aim of Linguistic sense teaching, which on one hand is to realize students" individual construction of literary works, and on the other hand construct their language ability and spiritual personalities. Feature of dynamics mentions that students" cultivation of linguistic sense ability is a process of long-time fostering and practice.

感悟性是立足于学生的角度，力图弘扬学生在语感教学中的主体精神；整体性是从言语作品的角度来说的，要求在语感教学中要立足于言语作品的整体进行宏观审视与系统把握；建构性是就语感教学的目的而言的，语感教学一方面要实现学生对言语作品的个性化建构，另一方面，要利用言语作品实现对学生言语能力与精神人格的建构；动态性特征指出了学生的语感能力的养成是一个需要长期涵养和训练的过程。

After analyzing the characteristic of the rigid plane motion and the shortcomings of classical digital image correlation algorithms, the phase-angle position of the rigid body in the 2D image was characterized by 1D sequence signals using the method of equiangular sampling feature extraction based on circle windows. Then the generalized correlation algorithm for estimation of time delay based on wavelet transform was used to acquire the angular displacement. Finally the ultrasonic radiation force acted on the micro-component was determined by the relation between force and motion.
