 The aim of the paper is the study of the orbits of the action of PGL4 on the space ?3 of the cubic surfaces of ?3, i.e., the classification of cubic surfaces up to projective motions. We then go on to identify the group up to commensurability class. We also construct the ideal of definition of such an orbital variety up to taking the radical. In this paper, we classify all smooth affine spherical varieties up to coverings, central tori, and ${\mathbb C}^{\times}$-fibrations. In addition, any infinite subset of $\cal M$ is complete up to a sign. 更多

In ordinary sampled-data control systems the system response to a step input can reach its equilibrium state only within n or more sampling intervals (n is the order of the controlled plant). In this paper multiple-impulses are used, instead of ordinary simple impulses, to speed up the system response. In such sampled data systems the system response to step input can reach its equilibrium state within less than n, even one, sam-pling intervals. Methods of design of such kind of sampled-data systems and their com-ponents are discussed. In the last part of the paper methods of compensating sampled data systems with dead time elements is also considered. 在通常的脉冲控制系统中,当输入信号是阶跃函数时,系统的过渡过程至少在n个采样周期内才能完全结束(n是控制对象的阶数).文中考虑了采用宽度不等的多拍脉冲代替通常的单拍脉冲以加快系统的过渡过程.在采用多拍脉冲以后,系统的过渡过程可以在少于n个采样周期内,甚至在一个采样周期内完全结束.文中叙述了这种脉冲系统的综合方法,也讨论了系统中有关组成部分——脉冲组成器和校正装置——的构成方案及其参数的计算方法.最后并考虑了由于时滞引起的对系统动态特性有害影响的补偿问题.文中举有例题,对文中各节内容作必要的说明. The dielectrie constants of toluene, carbon bisulphide, normal pentane, normal hexane, ethyl ether and iso-amyl alcohol were measured by a capacity bridge using a specially constructed liquid condenser at both 30° and 75℃ (22.4℃ only for the last liquid), for frequencies of 600,1000 and 2000 cycles per sec. and under pressures from 1 up to 12,000 kg/cm2. For the first four liquids, the dielectric constant is practically independent of the frequencies 作者用一电容桥及一特制之液体蓄电器以量甲苯,二硫化碳,正戊烷,正己烷,乙醚,及异戊醇之比电容。所用温度为摄氏三十及七十五度(异戊醇之温度仅为二十二度四),频率为每秒六百,一千及二千周,压力自一气压高至一万二千气压。前四液之比电容几与所用频率无关。(ε-1)/(ε+2)·1/d,(ε-1)/d及(ε~(1/2))-1/d三式中以第一式最近一常数,然压力渐增第一式之值恒随之而渐减,至一万二千气压时(在甲苯为九千五百气压),其减少约数在甲苯及二硫化碳为百分之三,在乙醚为百分之八,在异戊醇为百分之十九,显随电矩之增加而增加,至其原因篇中亦略加说明。 篇中图表惠蒙同事朱福炘先生代为抄绘,附誌谢忱。 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.

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云。 << 更多相关文摘
