In this paper, a survey is made over the existing theories of seismic forces onstructures. It is found that all the theories fall into one of the following cate-gories: 1) the so-called "statical theory" which considers the structure subject toan equivalent constant acceleration; 2) theories based upon simulated simplified ground motions; 3) theories based upon recorded actual ground motions; 4) theories based upon random impulses.

In this paper, a survey is made over the existing theories of seismic forces onstructures. It is found that all the theories fall into one of the following cate-gories: 1) the so-called "statical theory" which considers the structure subject toan equivalent constant acceleration; 2) theories based upon simulated simplified ground motions; 3) theories based upon recorded actual ground motions; 4) theories based upon random impulses. Critical comments have been given to the above theories, especially to thefourth one. The writer further gives a brief but cpmplete description of the responsespectra of the structure and on this basis, all the theories are co-related. Computations made by G. W. Housner for major American earthquakes dis-close that the acceleration spectra for damped system are flat curves withoutoutstanding peak value. For this reason, the writer deems that for certain typeof structures, variation of the acceleration spectral value for different modes of vibration will be small, and may be taken approximately as a constant. As aresult, the seismic forces reduce to this constant spectral acceleration times the.mass of the structure. It is suggested to use this method for estimatingthe base shear but make proper adjustment in its distribution along the height ofthe structure. It is also proposed to tie up this spectral acceleration to the earth-quake intensity scale. Finally, the writer stresses that further development of the theory of seismicforces on structures depends upon researches along following lings: 1) strong-motion program; 2) dynamical properties of structures and materials; 3) effectsof foundation conditions; 4) vertical and torsional seismic forces; 5) co-relationbetween seismic forces and earthquake intensity.

A general theoretical approach is developed to treat the effect of point imperfections on the spin waves in a ferromagnetic crystal. Special attention is paid to the formation of localized modes. As an example, the calculations have been carried out for a one-dimensional linear lattice. The main results obtained indicate the following features. A substitutional magnetic impurity atom may introduce more than one localized mode of spin waves. The conditions for the localized modes to appear and the positions of their energy levels are given in terms of J'S'/JS and J'/J. Here S' and S are respectively the spin quantum number of the impurity and that of the normal atoms. J' and J are respectively the exchange integral between an impurity and its neighbors and that between the normal neighboring atoms. Highly concentrated strains and interstitial atoms which cause the exchange interaction between the atoms in their neighborhood to increase lead also to the formation of localized modes. Furthermore, the dipole-dipole interaction has been taken into consideration with the conclusion reached that it should not destroy the existence of these localized modes. Discussions have been given to the discrete energy levels which appear below the continuous spectrum in case of J'<0. It is pointed out that the Holstein-Primakoff approximation adopted in the present work is not quite legitimate for certain cases in which on one or more atoms the spin deviation becomes not very much smaller than 2S or 2S'.

本文提出了一个处理磁性杂质或其他缺陷在磁性晶体中对自旋波频谱的影响的一般理论方法,并特别着重讨论了局域模自旋波。以一维线性格子为例进行计算的结果显示出:一个代位磁性杂质,可能产生不只一个高于连续带顶的局域模。其产生的条件和其能级位置均通过J′S/JS和J′/J表达出来,这里S′和S各为杂质原子和基质原子的自旋量子数,J′和J各为杂质与近邻之间和一般近邻之间的交换作用系数。高度集中的应变和间隙原子如致使邻近处的交换作用增大,也导致局域模的出现。我们也考虑了磁偶极矩相互作用的影响,证明其并不破坏这些局域模的存在。我们还讨论了在J′<0时,连续谱之下出现的局域模能级。我们也指出,在某些情况下,自旋偏离过于局域在较少数的原子上,本文中所采用的Holstein-Primakoff近似就不十分合法了。

Making use of a dichroic filter type anomaloscope,the ratio and the range of vatiation of red to green light in matching for yellow were Studied in 220 sub jectS(146 males,74 females) with no acquired diseases of COlour vision. of the 220 cases,207 are normal. The statistical properties of the distribution of their R/G ratios were analyzed,assuming a normal distribution.The rest,13 cases, constituting a total of 6% COlour defectives of the sample, consist of 3 protans,3 deutans,1 protanomal,2 deuteranomals and 4 extreme deuteranomals. The relative spectral sensitivity cur、vewas determined for 6 of the 7 anomalous trichromats and also for 5 normals. 2 protansand 2 deutans for the purpose of comparison. As an additional qualitative test,the ability of all subjects to tead the pseudo-isOChromatic plates (Ishihara,15 ed.) was also noted. on the basis of a correlated consideration of the present expental findings, the ways by which anomalous trichromatism might come into being were discussed in light of the prpoposal of Roshton regarding the cone pigment trans fomation from normal to dichromats. In order to account for certain behaviour of anomalous trichromats. it has been argued that,in addition to those types inVOlving a pigment transformation,as inthe case of dichromats,of only a proportion of the cell population,some cases probablyinVOlVC an abnormal formation of certain Digments which are not present in either the"red" or the "gteen" system. This abnormal pigment probably represents a certain inter mediate between that of P_(54) and (2P_(54)+3P_(59),thus accounting for a preferential settingof R/G ratio to certain values. In those cases of anomalous trichromat with little or noeviation of the mean value Of R/G ratio from normal but with mederately enlargedatching range,it is likcly that both the "red" and the "green" systems are affected tosome extent so as to make their spectral sensitivity curves approximately equal Therere,besides,even more complicated cases. The 6 anomalous trichromats are thus eterogenous group, DrObably reouiring different explanation for different cases.
