So the ultra-low frequency absolute vibration detection is a difficult problem in engineering measurement field. In this paper, the ""high-frequency-suppression and low-frequency-lifting"" compensation method was presented based on the analysis of the inertial sensor with "" mkc "" structure.

本文通过对mkc结构惯性式传感器机理的分析，提出了一种对传感器传递函数进行"抑高扬低"的补偿方法，并对此补偿网络和系统幅频特性进行了优化，较好地克服了惯性式传感器低频特性差的固有缺陷，实现了传感器的微型化。

Wavelet modulus maxima with high frequency and low frequency coefficients were obtained firstly through multiscale decomposition of well logging data;then important wavelet coefficients were chosen according to the fusion principle where high frequency coefficients were taken as maximal absolute values and low frequency coefficients were selected by edge detection principle;finally alternating projection algorithm was applied to reconstruct the fusion curve.

首先对原始测井曲线进行多尺度分解，得到不同尺度下的小波低频系数和高频模极大值；然后选用高频系数取绝对值极大、低频系数采用边缘法的融合规则，选取重要的小波系数；最后利用交替投影算法重构融合曲线。

The objectives of this research were students on third grade in junior high school whose study achievements were low. This research defined learning attitude as:"the attitude of learning contents","the attitude toward the teacher","the attitude toward school","the attitude toward selfhood". The research last one year by observing in teaching, using teacher's self-examination, students' learning papers, learning feeling questionary, and interview. The result were that thematic teaching improved the learning attitude of low study achievements students, and the degree of acceptancy of those students was high.

本研究以国中三年级学业成就较差的一个班级学生为研究对象，将学习态度界定为「对学习内容的态度」、「对教师的态度」、「对同侪的态度」、「对学校的态度」、「对自我的态度」五方面，研究历经一年完成；利用教学中的观察、教师反省日志、学生学习资料、学习感受问卷和访谈得知，运用主题式教学法可改善低学业成就学生的学习态度，且低学业成就学生对主题式教学活动的接受度也相当高。
