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...

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.

Magnetization curves of the polycrystalline Fe-Co and Ni-Co alloys of the cubic system and also of the pure cobalt were determined by means of a ballistic method. Gans' theory of the magnetic properties of isotropic ferromagnetics was applied. The agreement between his theory and the experimental results is quite good for the strong fields but not so for the weak fields, just as in the ease of the pure ferromagnetics. The discrepancy for the weak fields may be explained by his neglect of the free energy...

Magnetization curves of the polycrystalline Fe-Co and Ni-Co alloys of the cubic system and also of the pure cobalt were determined by means of a ballistic method. Gans' theory of the magnetic properties of isotropic ferromagnetics was applied. The agreement between his theory and the experimental results is quite good for the strong fields but not so for the weak fields, just as in the ease of the pure ferromagnetics. The discrepancy for the weak fields may be explained by his neglect of the free energy which is required to magnetize the elementary crystals isothermally to the saturation intensities in the easy direction of magnetization. After including this part of the energy the agreement between theory and experiment is improved in general and in some cases, it is remarkably good. For pure cobalt the magnetization intensities for a given field are smaller than those obtained by previous investigators, but in better agreement with the theory than those previously obtained. Since the disagreement cannot be accounted for by the experimental error in the present investigation, the comparatively less studied cobalt needs further investigation.

用冲击法量属於正方晶系之铁钴及镍钴合金并纯钴之多结晶体之磁化曲线与Gans氏各向同性铁磁物质磁性之理论相较知在强磁场时理论与实验之契合甚佳在弱磁场时则较差,弱磁场时之差异,可以Gans氏计算时略去磁化各元晶体於其易磁化方向至饱和度所需之自由能一点解释之改正此点后理论与实验之契合大体改善在数种合金且极佳。纯钴之磁化强度在各磁场下较之前人所得者均小,惟与理论之契合则较佳:此与前人不同之点既不能归诸本实验之误差,则此较少被注意之钴实需要更进一步之研究

(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.

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云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。
