Reductive group actions on affine quadrics with 1-dimensional quotient: Linearization when a linear model exists
      
Such an action is called linearizable if it is equivalent to the restriction of a linear orthogonal action in the ambient affine space of the quadric.
      
A linear model for a given action is a linear orthogonal action with the same orbit types and equivalent slice representations.
      
We prove that if a reductive group action on an affine quadric with a 1-dimensional quotient has a linear model, then the action is linearizable.
      
We find presentations for the irreducible crystallographic complex reflection groupsW whose linear part is not the complexification of a real reflection group.

The problem of optimizing the parameters of a steam turbine heat cycle may be treated as a non-linear programming problem and solved on an electronic digital computer.With this method, not only the calculation time is greatly reduced, but also the influence of various sub-loops may be considered. The computer program used is applicable to general heat cycle calculations. An example of heat cycle calculations for a type 51-50-3 turbine is presented.

汽轮机热力系统的最佳参数(最佳加热及分配)问题,在数学上可以归纳为求解多元非线性函数的条件极值。这类问题在电子数字计算机上应用非线性规划方法可以获得成功的解决。这不仅可以大大地加速计算过程,而且可以在计算中考虑各种辅助系统的影响。按本文编制的计算程序可以运用于各种热力系统。文中还附有对51-50-3型汽轮机所作的一些计算结果。

In this paper, an exact method to solve the forced oscillations and self-excited oscil-lations of relay servomechanisms with backlash is suggested based on the theory ofTsypkin. The effects of backlash on the periodic behavour of forced oscillations and self-excited oscillations are also discussed. In the system discussed, the relay has ideal charac-teristics with or without hysteresis loop; the linear part has transfer function of the formk/p(T_1p+1). The parametric regions for the existence of forced...

在崔普金理论的基础上,提出一种求解具有间隙的继电系统中强制振荡与自振荡参数的准确方法。同时亦讨论了间隙对周期现象的影响。所讨论的系统中,继电器具有理想继电特性(有回环及无回环);线性部分传递函数形如K/p(T_1p+1)。得出了系统存在强制振荡及自振荡的参量域。

In this paper, some methods of impoving the reliability of the non-crossing current thysister drive system for a planer are proposed. It is proved both in theoretical analysis and practice that it is more reliable in control logic to use delayed-locking and delayed-opening circuit. The speed regulator is discussed in detail.

In this paper, some methods of impoving the reliability of the non-crossing current thysister drive system for a planer are proposed. It is proved both in theoretical analysis and practice that it is more reliable in control logic to use delayed-locking and delayed-opening circuit. The speed regulator is discussed in detail. The effect of non-linear characteristics of the operational amplifier on system performance is analyzed. Both in theoretical analysis and practical experience show that in order to get the transient respones without overshoot, speed regulator with speed derivative feedback is more reasonable than ordinary PI regulator. The method of calculating parameters of the regulator is also given.

本文介绍了龙门刨可控硅供电无环流拖动系统中提高可靠性的一些措施。文中讨论了无环流逻辑控制方式,分析和实践证明采用延时封锁延时开放的方案更为可靠。文中还着重分析讨论了速度调节器的方案,分析了放大器非线性特性对速度调节系统的影响。理论分析和实践经验都说明,为了保证起制动过程中速度不超调,采用带速度微分反馈的速度调节器比一般常用的近似比例积分(PI)调节器更为合理。文中还介绍了调节器参数选择计算的方法。
