    The gravitational field and the motion of matter in the universe are investigated according to Einstein's field equations and his dynamical equations of motion. In a spatially isotropic and homogeneous space-time continuum it can be shown that up to about 2x10~8 l.y. the following relation holds between spectrum displacement δλ from distant spiral nebulae and their observa-tionally defined distance d,where A is Einstein's cosmological constant. The first term on the right hand side is essentially Hubble and...

    The gravitational field and the motion of matter in the universe are investigated according to Einstein's field equations and his dynamical equations of motion. In a spatially isotropic and homogeneous space-time continuum it can be shown that up to about 2x10~8 l.y. the following relation holds between spectrum displacement δλ from distant spiral nebulae and their observa-tionally defined distance d,where A is Einstein's cosmological constant. The first term on the right hand side is essentially Hubble and Humason's velocity-distance relation. The second part is a correction which amounts to 11.5% for d2x10~8 l.y. and hence lies within observational error of the present Mt. Wilson 100-inch telescope. The theory shows that both Milne's recent Newtonian theory of the expanding universe and Lemaitre's interpretation of tha velocity-distance are first order approximations and are valid only within 2xl08 l,y. from our galaxy. The calculation for the phenomsna of nebular recession beyond 2xl08 l.y. to be observed by the 200-inch telescope now under construction according to the present scheme will be presented in the near future.

    本文用安因斯坦力学及引力论解释宇宙之膨胀现象。从本文方程式中可证明雷猛德及米恒诸氏之学说皆为本文之近似值,而本文理论之能成立与否须恃200英寸反光镜完成后之观测

    The beta-ray spectrum of RaE was investigated by the cloud chamber experiments. About 600 tracks with H σ above 2000 were obtained. The spectrum was found to have an end point at 7500 Hσ. The average energy per disintegration was estimated to be 4.01×105 electron-volts.

    戊种镭原质(Ra E)所放出之β线穿过威尔圣成箱之径迹(tracks),用照相机照下。因成箱在磁场中,而磁力之方向又与β线所取之途径垂直,故由照片上所量出径迹之半径,ρ,可定β线之能力,盖磁场之强度,H,亦已知也。通常以Hρ代表能力大小之相当值。用戊种镭原质所摄之照片上量出10Oβ线径迹,其Hρ值皆在2000高斯-厘米(Gauss-cm.)以上。以各种Hρ值及在该值范围内所有径迹之数目作一曲线。将该曲线延长至与Hρ轴相交,其交点7500高斯——厘米,即为β线具有最大能力者之Hρ值。由β线能力大小之分配,用绘图方法得计算该线之平均能力,其值为4.01×10~5电子——伏特(electron—volts)。

(5) The null geodesies are preserved unfler an infinitesimal transformation of space-time along the temporal axis. It is obvious that the isotropic and homogeneous properties...

    By using elementary methods of Riemannian Geometry the Friedmann universe can be derived under the following rive postulates: (1) The space-time is Riemannian. (2) Einstein's field equations hold. (3) Matter and radiation in the universe are in a state of thermal equilibrium. (4) The world lines of all 'nebulae converge toward the past. (5) The null geodesies are preserved unfler an infinitesimal transformation of space-time along the temporal axis. It is obvious that the isotropic and homogeneous properties of space-time then follow as a necessary consequence.

    根据五个假定,即(1)空时间为利曼四度空间,(2)安世坦的引力定律,(3)宇宙中的物质与辐身成一温度平衡状态,(4)所有空时间中旋转星的世界线在过去曾相交叉,(5)空时间在时的方向经一无限小变换之后光子的零短程线仍为零短程线,本文用利曼几何的简易方法求得相对论宇宙论中的费烈特猛宇宙。
