Starting with the remote control system of a marine diesel engine, this paper furnishes some example for illustrating the position and functioning of the hydroelectric servo unit in the system . And based on the analytic method of classical control theory, it has made a preliminary performance analysis of Hagenuk's fuel oil gate servo positioner by which we can obtain some revelations for reference to further study of such mechanism.

The longitudinal-lateral automatic feed system for ablation lusting is developed for the purpose of developing several transient probes, improving the efficiency of arc heater ablation testing and the quality of testing results, The system has the capability of automatically controlling up to five models or probes per testing. It can drive the lateral flat by power stepping motor, so the model can arrive at the predictive position accurately with the displacement less than 0.1mm. The sweep speed for various probes is 0.08 m/sec to 0.43 m/sec. The longitudinal automatic feeder accurately compensates for the ablating recession of model through the use of laser positioner and fast clutch-brake unit. Success has been achieved as a result of adjusting the system in the laboratory and eliminating the electric-magnetic disturbance of arc heater. By the use of this system pressure profile, heat flux profile and enthalpy of the jet of arc heater have been measured by various transient probes. The efficiency and quality of ablation test have been improved immensely.

为发展各种快速探针,提高电弧加热器调试和烧蚀试验的效率以及试验结果的质量,我们研制成功了一套纵横向自动送进系统。该系统容许五个模型或探针参加试验。横向送进,采用大功率步进电机驱动,到位重复性优于0.1毫米,还能以0.08米/秒一0.43米/秒的速度扫掠各种快速探针;纵向送进,采用激光定位——快速离合器控制的直流电机驱动,可准确地补偿模型烧蚀的后退量。经过现场调试,排除电磁场干扰后该系统已获得成功。利用该系统各种快速探针测出了电弧加热器射流的压力剖面、热流剖面和气流焓值。烧蚀试验的效率和质量均得到了很大的提高。

We developed a YD-Ⅰ photo-electro-controllable positioner for intraocular foreignbody, which is used to regulate the hea1thyeye through a photo-electro control systemand have the injured eye radiated at themid position. We can reveal the cornea,orbit, foreign body and positioner imageson the lateral position with a polyvinylchloride shield before the injured eye, orplace the positioner in front of the eye butin no contact with the cornea, keeping aproper relation with the eyeball throughthe photo-electro control system. While taking radiography, the patientshould take the supine position. Anterio-posterior position: Place the probe in frontof the healthy eye, take 20 mm distance tothe top point of the cornea, switch on thelight source, advise the patient to gaze thesymbol in the probe so as to regulate theinjured eye to the mid position; then, placethe positioner in front of the injured eye,take 10 mm distance to the top point of thecornea, enable the central beam of X-rayto pass through the positioner and the pupiland radiate on the film vertically. Lateralpositon: Keep the original position, regulatethe X-ray tube at the level position, placethe lateral film box shelf at the outer sideof the injured eye, enable the central beamof X-ray to pass through the front of theinjured eye to the film. Using this X-ray positioner, we exam-ined 175 patients suffering from the intra-ocular foreign body, and the accuracy was98. 29%. Therefore, it is of great practical use.

作者对使用YD-Ⅰ型眼球内异物光电控制定位仪投照时的病员体位、眼球前后正位和水平侧位的定位操作及曝光条件等投照技术作了较详细的介绍,并对投照技术有关问题进行了讨论。
