In this paper the general synthesis problem of optimal control systems with the criterion of transient responses as a positive integral functional (3) is discussed.In the first part it is assumed that the motion of controlled object is described by a system of ordinary differential equations and that the final states of the system form a bounded and closed convex region in n-dimentional euclidian phase space. A method is proposed for finding all optimal control functions which lead any starting state into the given final region of states. Some conclusions are obtained from the maximum principle by using transversal conditions of optimal trajectories in terminal points, and the particular properties of the stated problem are pointed out. The case of linear dif-ferential equations with integral quadratic functional criterion is investigated in detail.Further, in the second part the fundamental properties of isoloss regions, the rela-tions between the isoloss region and optimal control functions are indicated. As a direct result a partial differential equation determining the optimal loss-function J (x) is found and the connection between function J (x)and optimal vector control function u (x) is also stated. The methods proposed are practically the extension of the me-thods used by us for designing time optimal control systems as seen in [5, 6 ,7].Finally, an example is illustrated with optimal trajectories shown in phase plane.The necessary numerical data is calculated by an analog computer with high accuracy.

文中研究了具有公式(3)表示的一般正积分泛函的最优控制系统的综合问题.在第一部分中研究了具有控制参数的一阶微分方程组.控制系统的终点状态为n维相空间内的某一逐段光滑边界的闭性区域Ω.文中指出了根据极大值原理和轨道终点的横截条件寻找引到Ω的所有最优轨迹的方法.这里详细地研究了具有二次泛函和被积函数中不明显含有控制参数的质量指标泛函的线性方程情况.在文中第二部分研究了等损耗区的主要特性.指出了等损耗区与最优控制函数之间的关系.导出了求算最优损耗函数J(x)的偏微分方程,以及这一函数与最优控制函数u(x)的关系.上述方法是我们曾在文献[5,6,7]中用过的最优快速系统的综合方法的推广.文章最后举有例证.

In this paper the writer employs complex Riemannian Geometry and defines the absolute interval between two points as consisting of a real part and an imaginary part. Two postulates (I) and (II) are used: the first may be called law of gravitation and electro-magnetism; the second equation of motion. In the absence of electromagnetic phenomena the theory reduces practically to Einstein's theory.

在此文内,作者利用复变来曼几何以宇宙间两点之距离为一实数及一虚数部分相构而成,於此并用假说:一可称为吸力及电磁定律,一为物体行动定律,解释吸力及电磁力之各种现象。在无电磁现象时,此文与爱因斯坦之吸力理论多相符合至於详细情形,容诸续篇。

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。
