For four years(1951—54)time determination data,after allowed for personal equation and referred to the mean observatory which is formed by the International Time Office(B.I.H.),seasonal fluctuation with amp- litude equals to 25 ms is found.That is,the clock corrections observed at Zi-Ka-Wei Observatory seem larger in May while smaller in February and July as compered with their annual mean. The Δ(α_α) type error of the fundamental catalogue(FK_3)contributes to the seasonal fluctuation with an amount of 6ms only....

For four years(1951—54)time determination data,after allowed for personal equation and referred to the mean observatory which is formed by the International Time Office(B.I.H.),seasonal fluctuation with amp- litude equals to 25 ms is found.That is,the clock corrections observed at Zi-Ka-Wei Observatory seem larger in May while smaller in February and July as compered with their annual mean. The Δ(α_α) type error of the fundamental catalogue(FK_3)contributes to the seasonal fluctuation with an amount of 6ms only. Inclination of atmospheric equi-density surface in pre-earth layer which is calculated with air pressure and temperature data taken from Shanghai and Lig-Yang(180km west of Shanghai)shows annual variation of 2′.5, thus the effect of refraction anomaly corresponding to the inclination calcu- lated is practically null. Besides,room refraction is also harmful.By the air temperature data taken from the east and west wall inside the observing room,the effect of room refraction thus estimated may become 8 ms in summer and turn to zero in winter. However,after draw out the influence of Δ(α_α) type error and room re- fraction,the seasonal fluctuation still appear.It is thought that thermal deformation of the transit instrument may be account for,as the diurnal change of air temperature and the temperature drop at night both signi- ficantly correlate to the seasonal fluctuation of time observation.

中星仪测时的组内符合程度比组外符合程度约高一倍,这已是人所共知的事实.一般认为引起组外符合程度较差的因素是仪器情况的变更和反常折射的存在.本文根据1951—1954年间徐台的天文测时结果求出它的季节性变化,并考虑星表误差、反常折射以及其他气象因素在测时结果所引起的影响.在上述期间,徐台天文测时所用的是一具口径80mm 焦距86cm 的帕兰(Prin)中星仪,附有马达带动人手操纵的接触测微器,仪器的水平轴是用水银盘控制的.主要的观测者为龚惠人(K),沈祖耀(S),罗定江(L)三人.

Spectral measurements of the solar radiation with a monoehrometer were made during the spring of 1968 from a 5000 metre altitude site of the Mount Jolmo Lungma region in Southern Tibet,China.From observations lasting more than a month,28 sets of solar spectral irradiance data with different air mass,corresponding to the four days of best observational conditions,were carefully processed.Through extrapolation they were used to determine the spectral distribution of the solar radia- tion in the near infra-red region outside earth's atmosphere(Table 5)and the mean atmospheric transmission in Mount Jolmo Lungma region(Table 3).The results are briefly discussed.

By use of Kaare Aksnes’revised predictions,six events including two of mutual occultation and four of mutual eclipse have been observed photoelectrically.The equipment used consists of a photoelectric photometer mounted on a 60cm Cassegrain reflector and a GGll filter. Part 1.Mutual Occultation Various criteria and formulae for the occulted area S and the occulted bright- ness I_j corresponding to various occultation configurations illustrated in Fig A-F are given in(2)—(20). The brightness distribution over the apparent disk of the occulted satellite f(R) can be solved from the integral equations involving I_j. It is shown from Tab.4 and Tab.5 that the occulted satellite J2 has a basically uniform disk with some limb brightening.It could be interpreted that the occulted J2 has no atmosphere or has only such a thin atmospheric layer that no limb-dark- ening is caused.Its brightness distribution over the apparent disk is caused by its surface feature.One may imagine that a concave area exists near the center of the surface confronting the observers. The actual measure shows that the drop △V in visual magnitude for the two satellites combined is by far larger than the predicted value.(See Tab.2).The observations also show that Harris values of albedoes for Jovian satellites are ques- tionable. A comparison is made between the observed and the theoretical light curves(Tab. 6 and Tab.7). Part 2.Mutual Eclipse Link's photometric theory of eclipse is generalized. The simplifying method of computing i_N is described in Section 5.Three theore- tical light curves computed by this simplifying method and their comparison with observed light curves are shown in Fig.11—13. In the final part of this paper,the integral equations(90)and(91)of reduced curves are derived and the methods of solving these equations are discussed. The radius of J2 is computed by iterative process from equation(1)′—(5)′. The observational materials of 1973.8.9.102P are used in the computation.
