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.

In this paper the logical structure of contactless telemechanical system for distributed objects is discussed. A simple method of variable system structure for transmitting and receiving telemechanical information is adopted. The idea is that the information oc-curred in every controlled point (station) and the information of some of those objects,which frequently change their states, are transmitted continually and cyclically, while for other objects their information is transmitted only after any change in their states. Thus,the speed of operation will be increased, and also the error probability of system syn-chronization will be decreased. For the realization of the variable logical system struc-ture, several blocks are used repetitively. For example, two commutators and one sim-ple logical unit are used to construct a simple automatic sequential encoder, and at the same time, the two commutators are used also to operate as a matrix commutator for receiving telesignalling information etc. Therefore the system is comparatively simplified and attains a higher degree of "minimization".

本文研究了无触点集中-分散目标远动系统的逻辑结构.文中提出了采用简单的系统变结构来发送和接收信息的逻辑结构方式.对被控制点及一部分比较重要或变化比较频繁的被控制目标的信息,保留了循环传送,而对大部分变化比较慢的被控制目标则采用目标有变化时才传送信号的方式,这样就提高了系统的平均动作速度,同时也减小系统的失步概率.文中采用环节的复合利用及简化的逻辑单元线路来实现这种系统的逻辑结构.例如用两个分配器和一个简单的逻辑单元“和”线路组成了很简化的选点自动程序编码器,同时这两个分配器又复合利用兼组成目标信号接收矩阵式分配器,因而可以使得这种系统同时又具有较高的极简化度.

The effect of pressure on photographic sensitivity is discussed on the experimental basis that the quantity E/EC, where E is the illumination actually used when the photographic emulsion is under pressure, and Ee the illumination which would be required to produce the same optical density when the emulsion is under no pressure, is a function of pressure only and that for pressures greater than a certain value, E/Ee becomes a linear function of the pressure.

当照相时,照相片子——映像纸,软片,或玻璃板——被压,则其感光性减弱,是为照相的压力效应。设E为照相片子在压力P下得光密度d所需之光照度,若片子不受压力则用光照度E_e即可得此同一之光密度d,故E_e可称在压力P下E之有效照度。吾人实验证明E/E_e为压力P之函数,当p>200kg/cm~2时,E/E_e与P成正比例。 此照相的压力效应,与照相时所用光之颜色,极有关系。黄色光较绿色光为显,绿色光较蓝色光紫色光为显至紫外光则几无此效应。 又此效应之大小,随各种照相片子而不同。就我们所研究的蔡爱斯伊康正色软片,伊司门人像软片,和矮克发色软片而论,以第一种为最大第二种次之第三种为最小。 这个效应,在实际上,或可有些应用。
