The paper introduces four fundamental circuit diagrams and their principles of rudder steer follow-up system.With a view to reduce the capacity of electrical machines in the system,the author analyses the function of saturated extent of magnetic circuit of the generator,the non-load characteristic of the excitor and the mechanical characteristic of the motor.Besides,in selecting the capacity of electrical machine,the correct duty rating of electrical machine,working environment and practical resistance-torque curve of the rudder-stock should be taken into consideration. Advanced technique and economical indexes in driving system of the rudder steer can be obta- ined through corrective seleetion of a gear ratio of transmission gear and rate speed of the motor, while an optimum gear ratio depends upon the least stored energy of running parts. In calculation of the transitional state characteristics,the author suggests the rule for discr- iminating the stability of a simplified linear follow-up system.With the help of property equation, further research on the effect of parameters upon stability may be made.For non-linear follow-up systems,the author considers that the electrical-mechinical transitional state of follow-up system may be obtained through the calculation of the differential equations by applying the limited multiplication method in order to observe the performance of driving system and its stability. Based upon practical experience,common problems of regulation and regulated methods have been summarized,of which the regulation of excited windings in the exeitor and the balanced resistors are emphatically pointed out.It has been found that the feed-back winding of the genera- tor has an effective result to reduce remained magnetism of the generator and overcoming“crept” of the motor produced by remained magnetism. The standard series of rudder steer follow-up system should possess the least grade of power,the most universality and the wide range of application.Through practice,the author suggests some circuit diagrams of rudder steer follow-up system and some opinions about the design of electrical machines.

本文介绍了四种基本的舵杌随动控制电力拖动系统的线路和原理。从降低系统中各电机容量的这个要求出发,分析发电杌磁路饱和程度、激磁机空载特性、电动机机械特性对拖动系统中各个电机的容量选择的意义。此外,在选择电机容量时,还必须考虑电机的确切工作制、工作环境和实际的舵杆阻力矩曲线。正确地选择电动机的额定转速和传动装置的传动比,可以获得舵机拖动系统的先进的技术经济指标,而传动装置的最佳传动比是以转动部分储能最少的原则来确定的。在动态特性的计算中,作者提出了简化的线性随动舵机稳定性判别法则,通过其中的特征方程式,还可以研究系统中各参数对于稳定性的影响。对于非线性直流同拍式随动舵机,作者认为采用有限增量法,通过对于十个独立的微分方程的运算,可以描绘出该随动舵机的电气、机械过渡过程,以此便能观察拖动系统的运行过程和稳定性。文章最后,根据实际经验,总结了调整的一般问题和调整方法,其中着重指出对于激磁机二组磁通方向相对的激磁绕组和平稳电阻的调整。经验表明:发电机电压负反馈绕组对于减弱发电机的剩磁和克服由此而产生的电动机的“爬行”会有显著的效果。作者认为随动舵机的标准系列应该具有最少的功率等级、最大的通用性和最大的应用范围。通过初步...

Objective [WT5”BZ]To report uncommon lesion of radial nerve paralysis with multiple constrictions. Methods Five patients were treated in our department from January 1994 to August 1999. There were 2 men and 3 women, with a mean age of 28 years (10 to 43 years). All patients were treated surgically. Periods from paralysis to surgery were 1 5 to 3 5 months(mean 2 4 months). The radial nerves were explored. There were 1 to 5 segmental constrictive lesions at the main trunks of radial nerves and the posterior interosseous nerves; no obvious extrinsic compression was noted. The nerves were twisted at the site of the most severe constrictions in 3 patients. One underwent epineurolysis. In the other patients the constricted portions of the nerves were resected, and the ends were sutured in one patient,nerve grafting in three. Histological examination of the resected portions showed concentration of inflammatory cells around the vessels in the perineurium. [WT5”HZ]Results [WT5”BZ]The patients were followed up for 8 months to 4 years after operation. Four patients regained at least grade 4 muscle power in the involved muscles. One patient who had been treated by nerve grafting regained grade 4 muscle power in the extensor digitorum communis, and grade 3 in the extensor pollicis longus 14 months after operation. [WT5”HZ]Conclusions [WT5”BZ]The lesion was very uncommon. The etiology may be a focal inflammatory response around the feeding arteries in the perineurium. The results of surgical treatment were good.

Methods Of the 72 female patients (mean age,48 years;range,8 to 86 years) with LUTS,46 had dysuria,14 with incontinence,10 with frequency and urgency of micturition and 2 with nocturnal enuresis.Urodynamic examinations were conducted in these patients. Results Among the 46 cases with difficulty of urination,whose bladder volumes were 60 to 800 ml,20 had the bladder detrusor contractility of 0,and 26,of 9 to 160 cm H 2O.Linearised passive urethral resistance relation (Linp-URR) figure showed at least grade Ⅲ obstruction in 19 cases.The urethral pressure profiles (UPPs) were 25 to 130 cm H 2O.Dyssynergia of detrusor-external sphincter occurred in 33 cases with voiding dysfunction.Ten cases with frequency of micturition had bladder volume of 97 to 450 ml.Two cases had the bladder detrusor contractility of 0,the other 8 cases were of 9 to 160 cm H 2O.Linp-URR figure showed at least grade Ⅲ obstruction in 2 cases.One case with urgent incontinence had hyper-sensitive bladder.The abdominal leak point pressures were 44 to 76 cm H 2O in 6 cases of stress incontinence.3 cases of overflowing urinary incontinence had no contraction of bladder detrusor and the UPPs were 32 to 42 cm H 2O.The UPPs were 0 to 16 cm H 2O in the 4 cases of total urinary incontinence.Two cases of nocturnal enuresis had detrusor instability with impaired contractility. Conclusions Urodynamic examination is necessary to the diagnosis of female LUTS and it also has significant value in predicting the treatment and prognosis of LUTS.
