An electrophotometric method has been worked out for the determination of magnesium in cast iron using titan yellow as indicator.Briefly,the method consists of dissolving the sample in dilute sulphuric acid,separating iron and other metals such as copper and nickel by electrolysis with mercury cathode and precipitating manganese from ammoniacal solution with ammonium persulfate.Ammonimn salt,silica and traces of aluminaare thenremoved. Finally,the prepared titan yellow reagent is added to the solutionand the magnesium content determined from the electrophotometric reading.The time required for each determination is approximately 5 hours. The effect of interfering elements which are likely present in cast iron such as manganese, silicon,phosphorus, aluminum, copper, nickel and vanadium as well as ammonium ion and alkali and alkaline earth metals has been studied and discussed.It has been shown that manganese, silicon, aluminum,copper,nickel,iron and ammonium ions can be removed down to such low values as to cause no significant interference.Phosphorus under 0.4% has no appreciable effect.Vanadium is not separated in the present method,but fortunately it is usually present in insignificant amounts in ordinary cast iron.The effect of calcium is compensated by the introduction of saturated calcium sulphate solution before the titan yellow addition. Potassium and sodium have no appreciable effect when present in small amounts. The results obtained by the present method for the determination of magnesium in 11 known samples are good,the average difference being 0.002% in a range of 0.000% to 0.140% Mg.The data obtained by the present method are also in good agreement with those obtained by gravimetric methods On seven nodular iron samples made by the Metallurgical Division of our Institute.A detailed procedure for the determination of magnesium in cast iron has been suggested and included in this paper.In view of its rapidity and fair accuracy,the new photometric method might prove useful for the purpose of control in a nodular iron foundry.

Utilizing the latitudinal mean ot upper meridional wind of 1950 given by Buch and Starr and White, mean meridional circulation has been studied. Fig. 1-3 (fig. 1 for whole year, fig. 2 for winter, fig. 3 for summer) reveal three cells: two direct cells in low and high latitudes respectively and one indirect cell in middle latitudes. The average jet stream of 1950 is situated in the middle cell. The yearly average equatorial convergence zone is at about 5°N. From winter to summer all the three cells shift northward. The Hadley cell of winter hemisphere extends to summer hemisphere. The intensity of these cells seems to be stronger in winter than in summer.Angular momentum balance for the latitudes 10°N-70°N for the year 1950 was also studied, and figure for stream lines for the transfer of angular momentum was constructed (fig. 5). The most interesting feature in this figure is that through the surface separating easterlies and westerlies the stream lines are vertical. Thus it indicates that the angular momentum generated in the easterlies is transported to the westerlies not in horizontal direction, but transported to upper westerlies in low latitudes by vertical motion. Then from there it is tiansfer-ed to middle latitudes. The mechanism of such transfer is as follows: In Hadley cell the upward motion in equatorial region and southern tropics carries more angular momentum due to earth's rotation, while the downward motion in northern tropics and subtropics carries less angular momentum due to earth's rotation. Thus in the mean angular momentum generated in easterlies is transported to upper levels.Finally the mechanism of maintenance of zonal circulation was discussed. The conclusion is this: In middle arid high latitudes gross disturbances are of primary importance while in low latitudes mean meridional circulation is important in maintaining zonal circulation.

本文利用了Buch和Starr与White所计算的1950年各纬度上空的平均经向风速([V]),绘制了子午面上的平均环流(全年:图1,冬季:图2,夏季:图3),图中显示出三个环型(cell),低纬度和高纬度的两个正环型与中纬度的逆环型。 1950年平均西风急流的位置正好处于中纬度的逆环流之中。全年平均的赤道辐合线位于北纬5°左右。自夏至冬三个环型均向北移,冬季半球Hadley环型伸向夏季半球去。三个环型的强度都是冬季大。 对于1950年北半球10°—70°的角动量平衡也作了分析(图4),并绘制了这个空间中角动量输送流线图(图5),其中应该提出,就是通过东西风的界面流线是铅直的,也就是总的来说,在东风带里产生的角动量不是在水平方向上输送到西风带里去,而是在铅直方向上输送到低纬度的高空西风里去,再由那里在水平方向上送到中高纬度去。 最后对于平均纬圈环流的维持也作了讨论,结论是:在中高纬度大型扰动起着主导作用,在低纬度则平均经圈环流是重要的。

The mode of genesis of plate-like structure of soils under different conditions may be different.Broad field observation reveals that soils favoring plate-like structure formation generally have an easy access to an abundant but intermittant supply of water,low content of raw organic matter as well as of humus,indefiniteness but not being too sandy in tex- ture,and weakness in structural stability. The present paper reports the evidences gathered from the field obser, vation and laboratory experiments showing that plate-like structure can be developed through the effect of alternate wetting and drying processes. Laboratory experiments have shown that the degree of perfection of the development of plate-like structure as evidenced both from the horizontal natural crackings and from the volume of swelling of the soil body in- creases with increase in the number of cycles of alternate wetting and drying.(Plate Ⅰ.)In order to assure the effectiveness of the processes, both drying and wetting should be carried out as thorough as possible. A mechanism explaining the formation of plate-like structure is pro- posed.According to the suggested mechanism,swelling of the soil as a result of wetting affords the necessary conditions for the formations of plate-like structure,while the actual development of structural plates is accomplished through the drying processes.The greater the rate of drying, the better the conditions for the development of plate-like structure. The horizontal axis of the structural plates as demonstrated by the laboratory experiments runs parallelly to the contour of the drying sur- face.The development of plate-Iike structure is greatly hindered by exerting pressure on the surface upon wetting.Microscopic examination of the structural units reveals that no definite orientation of the individual soil particles are noticeable and the horizontal crackings separating layers of structural plates were seen to be discontinuous and of non-uniform in dimension. The following is a brief account of the mechanism of plate-like struc- ture formation through the effect of alternate wetting and drying processes: The evaporation of water from the saturated soil leads first of all to the formation of a thin crust on the very surface of evaporation.This leaves,beneath the crust a series of cracking spaces parallel to the surface due to the shrinkage of the soil while drying.Further drying compels water to evaporate from below the surface into these cracking spaces. Thus a second layer of laminated dry soil may form below the first layer of the surface crust.As evaporation continues on,the process repeats itself with decreasing intensities because part of water will be lost inevitably through the few connections that may exist between adjacent layers of structural plates.The layers developed below the surface crust are of course somewhat different in nature because the conditions of drying pre- vailing here are different.Thus the drying out of the soil below the surface usually proceeds in a much more restricted rate——a fact,that may explain the presence of structural plates in the underlying layers which are absent in the surface crust.On rewetting the soil,the particles or aggregates in cracking spaces then may serve as wedges to push layers of structural plates further apart as a result of swelling. This theory may afford explanations to the facts that in the laboratory experiments better development of plate-like structure is always accom- panied by the greater extent of swelling of the soil and the latter in turn can be augmented by increasing the number of cycles of alternate wetting and drying processes.The proposed mechanism also suggests that not only should both wetting and drying be thorough enough so as to assure the formation of as many horizontal crackings and structural plates as possible, but also the rate of drying should be great enough to check as much as possible the lose of water through capillary action.It is also evident ac- cording to the supposition given above that any factor inhibiting the swelling of the soil,(such as pressure exerted upon the surface)will make it impossible to develope plate-like structure through alternate wetting and drying processes.As further evidences to support the suggested mechanism, it is worth while to point out the facts that plate-like structure usually occurs near the soil surface and that structural plates run always parallelly to the surface of evaporation. The soils that are most liable to the formation of plate-like structure according to this mechanism are those medium in texture,and low in organic matter and colloid contents. The plate-like structure thus developed is believed to be temporary in the sense that it will be easily disintegrated by either mechanical forces as practiced in the usual cultivation processes or by prolonged flooding followed by imcomplete drying.

一、片状结构形成的原因很多,但在地表常见的一种可能不是沉积、水冻或压力等原因造成,而系常经干湿变异的结果。二、在干湿变异条件下产生的片状结构分布地区甚广,可能其形成与土壤种类无直接关系。凡地面少植被、原缺乏结构的土壤,如不受人为翻动,露于地面一定时期后,多半会产生不同明显程度的片状结构。三、土壤在干湿变异条件下产生片状结构可能为一简单的机械作用。即土块湿润时膨胀,体积变大,再经干燥,体积不能恢复,留下横向裂隙于土中,遂成片状结构。在所研究的各因子中,干湿变异次数多、干湿变异程度大以及干湿变异中脱水速率快均能促使土块膨胀,所以能使片状结构形成更为明显。如对土块施以压力,不予膨胀,虽土块具有各方面生成片状结构的良好条件,仍不能形成片状结构。对田间具片状结构土块的试验中,说明它可能与室内人工片状结构有相同的成因,一方面也说明了这种结构的不稳定,易于破坏,但如条件适合,形成也不困难。四、此种片状结构因系土块干燥时产生横向裂隙所形成,所以结构横轴生成的方向主要决定于水分的蒸发面而经常与之平行。这种关系在野外具体表现为结构横轴常与地表平行,在室内的几项试验结果与此也相符合。此外结构横轴形成的方向是否与土块湿润时水分进行的...
