After summarizing the sources and effects of time lag in radio transmissions and receptions, we suggest a simple but accurate method to determine this particular type of error as occured in a radio receiver (Fig. 4 Section 3). The results proved to be satisfactory and were discussed in full.

本文中讨论了收時系统遲滯差的來源及其影響。并在適应一般的設備條件下,提出一精簡單而比较精确的测定方法。對於这種方法的試驗結果,我們作了详尽的比较与讨论。

The photoelectric micrometer and the automatic observation are tested on the Bamberg transit (D=90mm f=900mm). The photoelectric tracking micrometer is composed of photoelectric detector and servomechanism, It can bisect and track the star image. With instructions on the punched paper tape, it can control the mechanical transmission of motion, reverse the horizontal axis, point the telescope at the correct zenith distance, and determine the velocity of the servomechanism in tracking the motion of each star,...

The photoelectric micrometer and the automatic observation are tested on the Bamberg transit (D=90mm f=900mm). The photoelectric tracking micrometer is composed of photoelectric detector and servomechanism, It can bisect and track the star image. With instructions on the punched paper tape, it can control the mechanical transmission of motion, reverse the horizontal axis, point the telescope at the correct zenith distance, and determine the velocity of the servomechanism in tracking the motion of each star, and control the telescopic scanning track and guide. The photoelectric signal will record the time of transit. With this method of automatic observation, the personal equation will be eliminated together with delay error. It reduces the error caused by the noise due to the sky background, the photoelectric guiding and the atmospheric scintillation. Thus the accuracy of time determination will beenhanced.

本试验在邦贝中星仪上进行。光电测微器由原接触测微器、光电检测器和伺服跟踪机构组成,能自动对准和跟踪星像。由穿孔纸带指令操纵机械传动装置执行:转置水平轴、安放望远镜天顶距和确定伺服电机跟踪每颗星的速度、操纵望远镜扫描来实现光电寻星和导星。用光电测微器记录星过时刻和实现观测自动化后,能从天文观测结果中消除人差和光电装置的迟滞差;减小大气抖动、天空背景和光电装置的噪音、导星和操作仪器引起的误差,提高测时的准确度和精度。

The observational data of photoeletric transit during the past 15 years have been analysed. It is found that the fluctuations of results in time determination with this instrument are closely related to the variation of delay error which could induce the accidental leap or systematic variation of the observational results.

通过光电中星仪ZP1十五年观测结果的分析,我们发现:在光电中星仪观测中迟滞差值的变化与测时结果的波动是有很大关系的,就同一架仪器而言,迟滞差采用值的改变是导致观测结果的偶然跳动或产生系统变化的重要因素。
