Many oxides of heavy metals when existing not in exact stoichiometric combining ratios exhibit the properties of a semi-conductor.The resistance ofsuch materials has a very large negative temperature coeffcient.Such thermallysensitive resistors,known as“thermisters”,have found wide range of appli-cations in thermometry,communication engineering,etc.In this investigationwe tried over hundred samples of metallic oxides and their mixtures fusedwith glass powder to form small compact bead on Pt lead wires.The sampleswere treated by a new firing technique which is very convenient in laboratory.Some samples made from mixed oxides of Mn,Co and Ni showing a resistanceof 10~4-10~5 ohms at room temperature and 10-100 ohms at 500℃ seem.verypromising for practical purposes.

多种重金属的氧化物,经高温煅烧后,均可呈现电子性半导体的性质,其电导随温度急剧变化,故可作测量温度之用,通常称热感电阻。从电导的对数与温度的倒数的图中,可以推算半导体电导性所需的电子能位差。本文试验氧化物混入玻璃粉制成的小珠,用半导体体内电热法制成热感电阻,在常温时的电阻值为10~4—10~5欧姆,在500℃时只有10—100欧姆。半导体与铂导体线间的电性接触,经实验推知是良好的。这种制备方法,在实验室里,非常简易。经多次试验,以混合锰、钴、镍的氧化物和玻璃粉制成的电导性较大,有实用价值。

The rice stem borer, Chilo Simplex Butler causes great damage to therice crop in the medium semi-glutinous rice region, long water rice region,and late semi-glutinous rice region in Kiangsu. Rice stem borer has two generations a year. The first generation is mostabundant between mid-and late July. The second generation is most abundantin mid-late August. In 1952 and 1953, the borer had had reached and suchabundance cave in the middle of September, that a third incomplete generationseemed probable. Experimental result shows that late sowing and late transplanting of riceminimized borer damage.

(一)二化螟在江苏省中粳区、沤田区及晚粳区为害严重,大部分枯心苗均为其造成。白穗中幼虫数目相当高,最多一株有137头。 (二)二化螟的发蛾期,一般来讲,第一代盛发期约在6月中、下旬。第二代盛发期约在8月中、下旬。根据观察记载资料,望亭一带,1952年、1953年均在9月中、下旬又起高峰,可能有不完全第三代的出现。 (三)试验记录中指出,人为的移栽对蚁螟的生存,有抑制作用。在栽培制度上,应控制第一代蛾螟卵盛孵期,在秧田内进行。以期达到水稻少受二化螟的为害。 (四)水稻受二化螟为害后,除造成枯心苗白穗外,并造成有虫株。其百分率最高占14.5%。有虫株穗与健穗,穗重相差0.46克。千粒重最高相差3.09克。 (五)在稻根稻草中,二化螟越冬比例,稻根为43.41%,稻草为56.59%。 (六)在不同播种期;移栽期各处理间,受二化螟为害,差异显著。望亭一带适宜播种期、移植期,以5月25日播种,6月28日移栽为最佳。 (七)第一代螟卵之寄生率平均为25.46%。寄生蜂种类有:(1)日本赤眼蜂,(2)稻螟黑卵蜂。 (八)在防治上,除运用行之有效的治螟办法,如秧田捕蛾采卵、点灯诱蛾、剪除枯心苗和白穗、保护寄生蜂、处理稻根外,...

This paper investigates the general and complete form of slope-deflection equations used in structural analysis. The word "complete" indicates that all the possible deformations (deflections and rotations) and all the strain energies (due to shear, direct stress and flexure) are included in the equations. The definitions, numbers, and relations of member constants are then discussed and the general equations for computing these constants are given. By neglecting the factors of minor importance, the general form is reduced to the usual slope-deflection equations. Some special forms of such equations which are useful in certain practical problems are also discussed briefly, such as the slope-deflection equations including the effect of direct stress on flexure and the slope-deflection equations of semi-rigid frames. Slope deflection equations for trussed bents are also presented.

本文旨在:(1)提出完全的角变位移方程,使可精确的解算任何形式的平面刚构,只要其能视为由若干桿件组成即可。这里的所谓“完全”,系指方程中已包括一切可能的形变值在内,而且包括轴向应力及剪应力之影响。(2)全面的讨论桿件常数的定义、数量和相互关系,并供给计算各常数的最一般性公式。(3)将上述全面的和精确的公式逐步简化,以便与目前常用的公式比较。(4)讨论某些特殊情况。
