Once the configuration of a rigid frame (including the lengths, crosssections, supporting connections, etc. of all its bars) has been laid out, there exists one set of frame constants, which expresses the elastic characteristics of the frame, and, therefore, is independent of its loading condition. By employing these frame constants, not only the computations of the end moments of all the bars under any one loading condition are greatly simplified, but also, when the frame is to be analyzed under several loading...

Once the configuration of a rigid frame (including the lengths, crosssections, supporting connections, etc. of all its bars) has been laid out, there exists one set of frame constants, which expresses the elastic characteristics of the frame, and, therefore, is independent of its loading condition. By employing these frame constants, not only the computations of the end moments of all the bars under any one loading condition are greatly simplified, but also, when the frame is to be analyzed under several loading conditions, the computations related and not related to loading are distinctly separated, and, therefore, the repeated portion of computations for each loading condition, unavoidable otherwise, is entirely eliminated. As most of the rigid frames encountered in practice have to be analyzed always under many loading conditions, the practical superiority of the methods employing frame constants over other methods is thus obvious.

The object of the present work is to investigate the characteristics of piezo-electric resonantors which are cut from the natural coloured quartz, and compare the results with those obtained from those plates cut from the ordinary clear quartz in order to see if coloured quartz might be used as piezo-electric material in practice. In this work four points were stressed, they are: (1) the frequency constants of piezo-electric oscillation, (2) its stability, (3) its selectivity and activity and (4) its frequency-temperature coefficient curves. Further more a comparison of the characteristics of oscillations before and after the heat-treatment of the material was made. By the results of these experiments it concludes that the natural coloured quartz plates can be excited into piezo-electric oscillation and serve as piezo-electric resonantors. The frequency constant of a Y-cut plate from coloured quartz is about 2% lower than that of same type cut plate from clear quartz, while the frequency constants of the X-cut plate and the AT-cut plate from the coloured and clear quartz are practically the same. The heat-treatment to the three types cut plates of both kinds of quartz has a definite influence on their frequency. This effect is more pronounced to the coloured quartz plates. Likewise, heat-treatment improves, from the point-view of statistics, the selectivity and activity of oscillation of both kinds of quartz. Finally, the values of some coefficients of stiffness of the coloured and clear quartz were discussed.

本文的目的在于研究天然有色水晶在当作压电共振器用时它的压电振荡性能,并与无色水晶在这方面的性能上作一比较,以推断有色水晶是否可以应用到实际的控制电路振荡的工作中去。我们的工作分四方面进行:(一)有色水晶压电振荡的频率常数,(二)有色水晶压电振荡的稳定性,(三)有色水晶压电振荡的选择性及活动性,(四)有色水晶压电振荡的频率——温度系数。并且把有色水晶在用热处理方法去色后的这四方面实验结果与去色前的作一比较。实验的结果证明有色水晶是可以被激发压电振荡的,和无色水晶一样可以作控制电路振荡之用。有色水晶的Y-截法的频率常数比无色水晶的约低2%。至于两种水晶的其余两种X-截法及AT-截法的频率常数基本上无差别。热处理能使两种水晶的三种截法的压电振荡频率有增高的倾向,这效应在有色水晶中更为显著。同样,热处理对于两种水晶三种截法的压电振荡的选择性及活动性,在统计数字上看来是有益处的。最后,就以上测量的结果,推算了并讨论了有色水晶和无色水晶的若干劲度系数异同之点。

在过去曾在刚构的静力计算里面被广泛应用的弯矩分配法至今逐未见完整的应用于刚构 的自然振动计算中。原因第一是如何用分配法来判别自然振动还不够明确,第二是在振动计 算时分配传递收钦很慢甚至于发散,使计算繁难。本文中对节点没有位移的情况采用在刚架 任一节席 ∑K'=0 的判别式(其中E'代表动力修正刚劲度),如此可以利用连分式由已知 的边界向另一端推算,给出了简单明了的概念和计算方法。对节点有位移的情况应用了干扰 力等于零的判别方法,用直接分配法进行运算,避免了收钦很慢的缺席。这样就使得过去在 刚构静力计算里面能用分配法解决的问题也可同样的在振动计算上得到解决。
