This is the first of a series of papers with a view to evaluation activities inliquid blast-furnace-type slags.The purpose of this paper is to present new results of calculation for activities of CaO and SiO_2 in liquid CaO-SiO_2,CaO-SiO_2-Al_2O_3 and CaO-MgO-SiO_2-Al_2O_3 systems from existing chemical and electrochemi-caldata with certain assumptions The activities of CaO in the above-mentionedsystems with reference to solid CaO as the standard state are plotted against(%CaO)/(%SiO_2).From a comparison of these ~αCaO-(%CaO)/(%SiO_2)curves,a new expression for basicity has been proposed instead of the simple(%CaO)/(%SiO_2)ratio.The activities of CaO in the various systems concerned becomeapproximately equal at the same basicity when the latter is calculated accordingto the new formula.Alumina shows amphoteric behaviour in the new basicityformula in agreement with the general pattern of slag constitution.

在本文中,作者综合分析了关于CaO—SiO_2、CaO—SiO_2—Al_2O_3及CaO—MgO—SiO_2—Al_2O_3系统熔渣中α_(SiO_2)及α_(CaO)的测定结果,并加以比较。关于CaO—SiO_2二元系,作者综合了Fulton与Chipman,张禄经与Derge及坂上六郎的实验数据,导出了1600℃时液态渣在整个浓度范围内的α_(SiO_2)及α_(CaO),分别用β鳞石英及固态CaO为标准状态。根据这样算出的α_(SiO_2)及α_(CaO)以及坂上的CaO侧电动势数据,作者导出了一个经验公式,可以用来从已知的电动势数据与α_(SiO_2)计算α_(CaO)。将这个公式应用于CaO—SiO_2—Al_2O_3三元系,算出了三元系熔渣内当Al_2O_3=10、20%时的α_(CaO)。然后将二元系和三元系中的α_(CaO)加以比较,导出了一个新的碱度计算公式。在此式中A1_2O_3显示双性,当碱度较高时它属于酸性,因此可以分子比例与SiO_2相加;反之,当碱度较低时它属于碱性,因此须从SiO_2中扣去。如将MgO以重量百分率与CaO相加,这个碱度公式也可以适用于四元系。由于新的...

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。
