The new coefficient Q″proposed by E.E.Golikov as the general and single-valued criterion for evaluating the acoustics of rooms and auditori- ums have been critically examined,with detailed discussionsconcerning:(1) the empirical foundation of the articulation-Q″functional relationship A= f(Q″),(2)the derivation of the“particular criterion”or the optimum re- verberation condition form Q″,(3)the meaning of a time integration of the “noise-interference factor”as viewed from the theorey of auditory perce- ption,and(4)the“crux”of...

The new coefficient Q″proposed by E.E.Golikov as the general and single-valued criterion for evaluating the acoustics of rooms and auditori- ums have been critically examined,with detailed discussionsconcerning:(1) the empirical foundation of the articulation-Q″functional relationship A= f(Q″),(2)the derivation of the“particular criterion”or the optimum re- verberation condition form Q″,(3)the meaning of a time integration of the “noise-interference factor”as viewed from the theorey of auditory perce- ption,and(4)the“crux”of the original papers—the definition of the “noise factor”that was introduced in somewhat albitrary manner. It has been shown with illustrative examples that the adequateness of this coefficient is rather limited when used as an empirical formula,and its versatility strongly denied,for the insufficient and often misleading theo- retical basis with which the Q″-expression was derived.Further extensive studies of the problem of speech masking by reverberation both in tbeorey and in practice have been suggested as prerequisite for a formulation of any quantitative link of the sort.

本文就提出的评价房屋音质的新系数——普遍而单值的标准 Q″作了一些评述。主要内容有:(1)以在不同的条件(如语言、测试人员、宣读方式以及声学场所等)之下的清晰度测验结果来验证 A=f(Q″)函数的适用性,(2)判断了从Q″来推求以体积为参数的最佳混响时间的可能性,(3),从听觉理论来讨论“混响干扰因子”对时间积分的意义,(4)讨论了原作者对“噪声因子”的看法,指出了“噪声因子”定义中的一些值得存疑之处。总的来说,我们发现 A=f(Q″)作为一个经验函数来说,其局限性是很大的。原作者所提出的某些理论根据也是不够充分的。文中对原作者的某些见解及其为建立一个联系清晰度与客观声学条件所作的努力,作了肯定的估计。同时指出,要完善地解决单一化音质参量的问题,必须先在实验上和理论上对语言的混响遮蔽问题作更多的研究。

The semiempirical rules of the thermodynamical properties of oxide systems have been proposed by the pattern recognition technique with chemical bond-parameter, and an empirical function L has been suggested as a scale for the acidity or basicity of oxides. It seems to indicate that the correlation between L and such physico-chemical quantities as the heat of formation of complex oxides, the heat of mixing of oxide melts, the activity coefficient and polymerization equilibrium constant K_(1,n) of Masson's model...

The semiempirical rules of the thermodynamical properties of oxide systems have been proposed by the pattern recognition technique with chemical bond-parameter, and an empirical function L has been suggested as a scale for the acidity or basicity of oxides. It seems to indicate that the correlation between L and such physico-chemical quantities as the heat of formation of complex oxides, the heat of mixing of oxide melts, the activity coefficient and polymerization equilibrium constant K_(1,n) of Masson's model of slags may be presented respectively. The applications of L function are illustrated with some examples.

In this paper, a statistical forecasting experiment for the synoptic situation of subtropical high in the later period of "Mei-Yu" is performed by the use of empirical orthogonal functions. In this experiment, the empirical orthogonal functions are calculated by statistical method. The data are taken from 500 mb daily geopotential height, from June 1 to 30, 1960.The development tendency of subtropical high, moving westward or northward, or maintaining, can be forecasted, if the method of self-regression in time sequence is used. The time interval is 1 day. The predicted results are almost not affected by the boundary of the domain, which indicats that the effect of time-advection is present.

本文叙述用经验正交函数序列作梅雨结束期副热带高压天气形动的统计预报试验。试验用1960年6月1—30日20时每天的500毫巴高度资料统计计算经验函数。采用预报时间间隔为一天的时间序列自迴归方法,可以预报出副高西进、北抬与维持的趋势。预报结果几乎不受预报区域边界的影响,说明存在时间平流作用。
