Fineness modulus (F. M.) has served as an index of fineness of aggregates since it was first introduced by Prof. Duff A. Abrams in 1918. In the concrete mix design, the F. M. of sand governs the sand content and hence the proportions of other ingredients. But there are undesirable features in F. M.: it does not represent the grading of sand and manifests no significant physical concept.Prof. suggested an "average diameter" (d_(cp)) in 1943 as a measure of fineness of sand. In 1944, d_(cp) was adopted in 2781-44 as national standard to specify the fine aggregate for concrete in USSR. It was introduced to China in 1952 and soon becomes popular in all technical literatures concerning concrete aggregates and materials of construction.After careful and thorough investigation from ordinary and special gradings of sand, the equation of d_(cp) appears to be not so sound in principle and the value of d_(cp) computed from this equation is not applicable to engineering practice. The assumption that the initial average diameter (ν) of sand grains between consecutive seives is the arithmetical mean of the openings is not in best logic. The value of an average diameter computed from the total number of grains irrespective of their sizes will depend solely on the fines, because the fines are much more in number than the coarses. Grains in the two coarser grades (larger than 1.2 mm or retained on No. 16 seive) comprising about 2/5 of the whole lot are not duly represented and become null and void in d_(cp) equation. This is why the initiator neglected the last two terms of the equation in his own computation. Furthermore, the value of d_(cp) varies irregularly and even inversely while the sands are progressing from fine to coarse (see Fig. 4).As F. M. is still the only practical and yet the simplest index in controlling fineness of sand, this paper attempts to interpret it with a sound physical concept. By analyzing the F. M. equation (2a) in the form of Table 9, it is discovered that the coefficients (1, 2…6) of the separate fractions (the percentages retained between consecutive seives, a1, a2…a6) are not "size factors" as called by Prof. H. T. Gilkey (see p. 93, reference 4), but are "coarseness coefficients" which indicate the number of seives that each separate fraction can retain on them. The more seives the fraction can retain, the coarser is the fraction. So, it is logical to call it a "coarseness coefficient". The product of separate fraction by its corresponding coarseness coefficient will be the "separate coarseness modulus". The sum of all the separate coarseness moduli is the total "coarseness modulus" (M_c).Similarly, if we compute the total modulus from the coefficients based on number of seives that any fraction can pass instead of retain, we shall arrive at the true "fineness modulus" (M_f).By assuming the initial mean diameter (ν') of sand grains between consecutive seives to be the geometrical mean of the openings instead of the arithmetical mean, a "modular diameter" (d_m), measured in mm (or in micron) is derived as a function of M_c (or F. M.) and can be expressed by a rational formula in a very generalized form (see equation 12). This equation is very instructive and can be stated as a definition of mqdular diameter as following:"The modular diameter (d_m) is the product of the geometrical mean ((d_0×d_(-1))~(1/2) next below the finest seive of the series and the seive ratio (R_s) in power of modulus (M_c)." If we convert the exponential equation into a logarithmic equation with inch as unit, we get equation (11) which coincides with the equation for F. M. suggested by Prof. Abrams in 1918.Modular diameter can be solved graphically in the following way: (1) Draw an "equivalent modular curve" of two grades based on M_c (or F. M.) (see Fig. 6). (2) Along the ordinate between the two grades, find its intersecting point with the modular curve. (3) Read the log scale on the ordinate, thus get the value of the required d_m corresponding to M_c (see Fig. 5).As the modular diameter has a linear dimension with a defin

細度模數用為砂的粗細程度的指標,已有三十餘年的歷史;尤其是在混凝土的配合上,砂的細度模數如有變化,含砂率和加水量也要加以相應的調整,才能維持混凝土的稠度(以陷度代表)不變。但是細度模數有兩大缺點,一個是模數的物理意義不明,另一個是模數不能表示出砂的級配來。蘇聯斯克拉姆塔耶夫教授於1943年提出砂的平均粒徑(d_(cp))來,以為砂的細度指標;雖然平均粒徑仍不包含級配的意義,但是有了比較明確的物理意義,並且可以用毫米來度量,這是一種新的發展。不過砂的細度問題還不能由平均粒徑而得到解决,且平均粒徑計算式中的五項,僅首三項有效,1.2和2.5毫米以上的兩級粗砂在計算式中不生作用,以致影響了它的實用效果。本文對於平均粒徑計算式的創立方法加以追尋和推演,發現其基本假設及物理意義,又設例演算,以考察其變化的規律性;認為細度模數還有其一定的實用價值,不能為平均粒徑所代替。至於補救細度模數缺點的方法,本文試由模數本身中去尋找;將模數的計算式加以理論上的補充後,不但能分析出模數的物理意義,並且還發現模數有細度和粗度之別。根據累計篩餘計算出來的F.M.應稱為“粗度模數”,根據通過量計算出來的才是“細度模數”。假定兩隣篩间的顆粒是...

(1) White mice were exposed to 40 cercariae of Schistosoma japonicum on the abdomen for 3, 5, 10, 15 and 20 minutes. Five weeks later, mice were killed and searched for worms. The percentage of worms recovered in the 5-minute group was found to be low (33%), whereas the differences between those in the 10-minute (45%), 15-minute (51%) and 20-minute (54%) groups were non-significant. (2) Infected mice were treated with tartar emetic given by mouth for 2 weeks. After a holding period of 1, 2, 3 or 4 weeks, mice were sacrificed. The differences between the number of worms remained in the 4 groups of mice were non-significant. Therefore, one week may be adopted as the holding period in the screening test for antimonials. (3) In the control group and in the treated group with tartar emetic 270 mg/kg/day, there was no significant difference between the number of worms remained in male and in female mice. But in the treated group with tartar emetic 170 mg/kg/day, the number of worms remained in female mice was less than that in male mice. Hence it is advisable to use equal number of both sexes of mice in experimental therapy. (4) After the treatment with tartar emetic, mice were divided into 2 grades according to the body weights. The number of worms remained in mice of the 2 grades revealed a significent difference only in the group with holding period of 3 weeks, but not in other groups.

(一)小白鼠腹部皮肤感染40条日本血吸虫尾蚴,感染时间自3至20分钟不等,5周後解剖,检查成虫数,发现感染尾蚴5分钟的成虫发育率较低(33%),而感染10分钟(45%),15分钟(51%)及20分钟(54%)之差别不显著。 (二)病员经口服吐酒石治疗2周後停药1,2,3或4周解剖,发现余存虫数之差别并不显著。所以可用1周作为比较锑剂疗效试验的停药时间。 (三)对照组及吐酒石270毫克/千克/天剂量组内,雌雄鼠体内余存虫数相差不显著,但在吐酒石1700毫克/千克/天治疗组内,雌鼠体内的余存虫数少於雄鼠体内的虫数。所以实验治疗所用的小白鼠最好是雌雄各半。 (四)吐酒石治疗後大小两级体重鼠体内余存虫数,仅在停药3周组内有显著的差别:其他组内则未见显著差别。
