It proposed improving English learning ability with encouraging skills.

In the course of managing of institutions of higher learning, scientific choose of encouraging techniques are the efficient ways to arouse the enthusiasm of staffs to bring their creativity into full play and to improve education quality and running level, therefore, it is necessary to study the encouraging factors, the following article will qpproach the above-mentioned subject from six aspects.

This paper discusses the main points of the training in the praising and encouraging skill in view of forming proper viewpoints on students, building up the teacher s prestige, fostering the teacher s close relation with students and their parents and establishing an encouragement mechanism.

Objective:To study the application value of Principle Of Selective Excitation Technigue(PROSET) in depicting morphological features of normal lumbar root and diagnosing diseasea of lumbosacral nerve root.

Based on the Hilbert-Huang transform(HHT) and natural excitation technique(NExT),the natural frequency and damping of a model arch dam are identified through vibrating table tests.

The natural excitation technique(NExT) and the eigensystem realization algorithm(ERA) were combined to identify the modal parameters in the time domain in a structure excited by simulated ambient vibrations.

In the method,the transition from structural random response to deterministic response was realized by the natural excitation technique(NExT).
