Following the recently fixed new norms with respect to floor area for each family unit,it is deemed necessary to give more careful reconsideration to the housing design problem.During the past years,valuable data and experiences have been acquired in the course of housing developments,but it appears advisable, at this stage,to make further efforts to analyse more thoroughly into this problem with a view to achieve a more rational,logical and satisfactory solution in our modern housing design. The author attempts to give a brief review of the current housing plans, comparing the effectiveness of floor space destributed inside and outside of the units, discussing the“K-values”,the application of small multl-purpose vestibule and measures taken for land saving in the course of planning. The necessary of plastic variety in contradiction with the monotony of constantly repeated prefabrication and mechanized construction process has also been discussed. The author also mentions the possibility of creating a more lively spatial composition by proper massing arrangement of the houses,green areas,facility buildings etc and to achieve a more attractive appearance by proper variation of details,of texture and of colour schemes etc. It is presumed that in the domain of housing design,plenty of research work could be done,and it hoped that hundred flowers will blossom.

长期的住宅建设积累了可贵的经验,但为了提高住宅设计的水平,尚应提倡在理论上作深入分析与探讨。居住面积定额的新规定,对住宅设计又提出了新的的问题。作者认为分析住宅平面应从户内外面积分配来着手,并列举了一些常见住宅平面进行比较分析。同时还指出沿用巳久的K值在现阶段巳不能作为主要经济指标了。文中讨论了小方厅的设置,并对平面进深.每户平均面宽与节约用地的关系提出看法。作者还提出了应从住宅群体结合绿化,道路及福利设施组成丰富多彩的空间效果。而住宅单体应在标准化基础上考虑细部色彩等的变化,以达到既协调又多样,也顾及了施工的工业化。本文最后还举例说明住宅设计有不断革新的必要与可能,住宅设计的提高有待于设计人员作出不懈的努力。

The function of terminal immittance of ladder network expressed by continued fraction is directly related to parameters of the elments in the ladder. The ladder network properties are uniquely determined by the network function in form of a rational fraction which is the inversion of the continued fraction. It can be proved that the voltage ratio transfer function is easily obtained from the reciprocal of numerator polynomials of the rational fraction of the input impedance, while its denominator reciprocal forms transfer function of transfer impedance. The process of reducing continued fraction to rational fraction is known as inversion and the reversed process called expansion. The purpose of this paper is to find an easy and simple way for both the expansion and inversion processes between rational and continued fraction functions by means of Routh Algorithm. This method will also lend great conveniences to the analysis and aynthesis of ladder network, and at the same time tightly relates this two otherwise independent tasks, Actual computation reveals this method can effectively render the analysis result more exhaustive and that of the synthesis more rational and closer to preassigned goals which also include the economic advantages attainable.

梯形网络的终端阻抗(导纳)函数的连分表达式,直接与网络的各个元件参数联系着,而上述网络函数的有理分式形式却决定了网络的各种特性。输入阻抗函数之有理分式其分子多项式的倒数就是电压传递函数,其分母多项式的倒数就是转移阻抗函数。由连分弍到有理分式的变换过程称之为反演,反之称为展开。本文中将借助于Routh算法来完成这种反演与展开,使计算工作量大大减少,从而方便地实现对梯形网络的分析与综合。同时,使分析与综合紧密联系,就象送运算与正运算的关系一样。这样做使分析的结果更切合实际;综合的结果更符合预定的指标,其中包括经济性指标。 对均匀梯形网络和锥状(tatper)梯形网络本文提供了专用的连分式反演表,只需查表就可以求得电压传递函数和转移阻抗函数。本文还推广了Tschudi公式的应用范围。参考文献共41篇。

As is well known,the mechanism of La3+-NaY ion-exchange reaction reviewed by H.S.Sherry has been mainly ascribed into two steps.The second step of them called the slow step is proposed as the rate-controlling step in the whole reaction with respect to the stripping of water molecules from the hydrated La3+ ion in the large cavity in relation with the replacement of Na+ by La3+ in the β-cage.The corresponding activation energy can be estimated by the enthaly of hydration of La3+ ion.Although the assumption of the rate-controlling step is reasonable,there is still lack of exact experimental evidence.It is to make a deeper understanding of the slow step by means of experimental devices.The arrangement of measurement condition at elevated temperature may facilitate the systematical study of the behaviour of this kind of ion-exchange reaction.The present authors have investigated the slow step at an elevated temperature in three aspects;1.To measure the ion-exchange isotherm,for La3+-NaY system at 100℃and 180℃ respectively.2.To investigate the degree of ion-exchange of individual LnY at 180℃ and to compare the results with the enthalpy of hydration of Ln3+ ions.3.To evalute the rate-constant and apparent activation energy of the slow step at elevated temperature from our experimental data.As a result,a more rational mechanism of La3+-NaY ion-exchange reaction is proposed.Ⅰ.La(H3O)93++ NaY(s)→La(H2O)93+Na(SI)F(s)+Na+Ⅱ.La(H2O)93+(in large cavity)+La(H2O)93+Na (SI)Y(s)→La(H2O)93+LaY(s)+Na+Eq-Ⅱ should consist of the following two consecutive reactions;Ⅱ-A.La(H2O)93+ (in large cavity)→La3++9H2OⅡ-B.La3+ + La (H3O)93+Na(SI)F(s)→La(H2O)3+LaY(s)+Na+Eq-Ⅱ-A is the rate-controlling step for this ion exchange reaction.
