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.

Specimens of A-cast high-C high-Cr tool steel were compressed along two perpendicular directions. Result of metallographic examination shows that there are two aspects to the breakdown of eutectic carbide structure: scattering of eutectic carbide network and breaking down of carbide particles. To break down the eutectic carbide network of A-cast structure with grain size 4-5 grade, tensile strain of 60% is needed. When the specimen is alternately deformed along two perpendicular directions, carbide particles are smaller and more evenly distributed. Small ingots were drawn out into billets with various operations. The result shows that when cross sectional area of the ingot is reduced to one-tenth, eutectic carbide network beging to scatter. When cross-sectional area is reduced to one four teenth, carbide particles distribute somewhat like bands. When ingots were drawn out with flattening of breadth and height ratio more than 2 and flattening alternately on two perpendicular sides more than 3 times, the breakdown of eutectic carbide structure is more complete than that without flattening, especially in the central part.' Meanwhile there appears no band structure when ratio of reduction area is large. When ingot is upset at first, then drawn out with flattening, it is the most effective forging process to break down eutectic carbide structure. Result of impact testing with circular-arc notch shows that impact value of forged billet is closely related to the stages of breakdown of eutectic carbide structure. Hence it is suitable for evaluating the mechanical property of tool steels.

将铸态高铬模具钢试样经不同方向的反复变形试验后,结果表明共晶炭化物组织的破碎过程包括网状组织的分散和片状炭化物颗粒的折断两个方面。当铸志晶粒度力4~5级寸,破碎晶炭化物组织需要有60%以上的拉应变。不同方向的反复变形使网状组织分散得更好,炭化物颗粒断裂得更细小。 用不同方法将高铭模具钢小钢锭锻成钢材的试验指出,当锻比大于10时,网状共晶炭化物组织已经破碎,锻比大于14,会出现带状分布。采用走扁方的引伸,如扁方度大于2,不同方向的走扁方次数在三次以上时,和不走扁方的一般引伸方法比较,钢材达到同样的共晶炭化物破碎程度时锻比可以小些,中心部位破碎得较好。同时当锻比较大时,不出现带状组织。如将钢锭先经过墩粗,压下量大于50%,然后再用走扁方引伸成钢材,这是破碎共晶炭化物组织最有效的锻造方法。 用带圆弧缺口的冲击试验结果表明冲击值和钢材的共晶炭化物组织破碎程度有密切关系,可以作为性能指标。

Initial temperature distribution of the nebulous disk around the sun led to the bordering region between the asteroids and Jupiter becoming a transitory region, in which the“icy”matter changed from uncondensed state to condensed state. The discontinuity in chemical constitution makes the projected surface density of solid condensate in the inner portion of the Jupiter region bigger than the mean value in the asteroid region, and the time taken for dust particle to precipitate becomes comparable to that in the asteroid region. Owing to gravitational instability, the dust layer then broke up into clusters of particles, each cluster transforming into a planetesimal. The mass of such plenetesimal and the rate of its growth in the Jupiter region are bigger than those in the asteroid region. Perturbation and mutual encounter between large planetesimals in the inner portion of the Jupiter region, changed their orbits, and produced rather large relative velocity. Part of such planetesimals entered the asteroid region, drew out most of the matter there, and increased the random velocity of the asteroids that remained, so they could not combine to form a planet. We prove the above view through quantitative analysis in this paper.

太阳周围的星云盘的初始温度分布使得小行星和木星的边界区成为冰物质从不凝聚到凝聚的过渡区。化学组成间断性使得木星区内侧固态可吸积物质的面密度比小行星区的平均值大,使尘粒沉降所需时间和小行星区相差不多。尘层由于引力不稳定而瓦解为粒子团,粒子团转化为星子,其质量是木星区的比小行星区的大,星子的生长率也是木星区的较大。木星区内侧大星子间的摄动和相遇改变了它们的轨道,产生了较大的相对速度。一部分大星子进入小行星区,拉走了大部分物质,增加了留下的小行星的随机速度,使该区内形成不了大的行星。本文通过定量分析,证明上述论点。
