Combined with the research project of the advanced performance of wire rope in the port cranes , a key technological problem of the ministry of communications , this dissertation investigated the stress - effect on the magnetic flux leakage ( mfl ) of wire ropes and the law of the mfl signal changes during wire rope fatigue testing by experiments and modern signal processing methods based on the ferromagnetic theory , being aimed at the present problems of current wire rope testing technology . the characteristic parameters and quantitative descriptive specifications for wire rope defective signal were analyzed in detail . this dissertation present a novel method of quantitatively evaluating locate faults ( lf ) 本文结合交通部重点科技项目“港口起重机钢丝绳传动件的高性能技术研究” ，针对当前钢丝绳电磁检测技术中所存在的问题，以铁磁学为理论基础，以试验和现代数字信号处理技术为手段，对钢丝绳漏磁信号的应力效应、钢丝绳疲劳损伤历程中的漏磁信号变化规律做了深入的研究，对钢丝绳缺陷信号的特征参数和缺陷的定量描述指标做了详细的分析，提出了一种局部缺陷的定量逼近方法。
The monitoring system of the controlled passively anti - rolling tank model performance takes charge of control and regular service of anti - rolling tank . accomplishing the hardware design and software programmed of tank control , data acquisition , we process the model test of the controlled passively anti - rolling tank . according to signals of the roll angle and water level , the control system output signals to open or close the valves , and achieve some stabilized effects 本文系统地介绍了可控被动式减摇水舱监控系统的硬件设计和水舱控制、数据采集软件程序实现工作，然后进行了可控被动式减摇水舱进行了模型试验，根据横摇角度和边舱液位的信号变化来控制气阀的开启和关闭，取得了一定的减摇效果。
In this research , four experiments had been designed to study the patterns and characteristics of semg signal by linear and nonlinear signal analysis methods during the short period of recovery , ischemic forearm exercise , sustained and intervallic maximal voluntary contraction of biceps brachii in twenty - eight human subjects 为探索肌肉疲劳过程中影响semg信号变化的生理因素，本研究采用线性和非线性混沌动力学两个方面的分析方法，观察在各种控制条件下的肌肉疲劳或恢复过程中semg信号的变化规律。
