A method based upon the differences in ultraviolet absorption of the purine and pyrimidine bases at different pH is developed for the analysis of these components in purified ribonucleic acid. In a solution containing adenine, guanine, cytosine and uracil, optical densities are measured at 4 different wave lengths both at pH 1 and pH 13, and the amount of each base can be calculated by making use of the proper optical density differences.

A method based upon the differences in ultraviolet absorption of the purine and pyrimidine bases at different pH is developed for the analysis of these components in purified ribonucleic acid. In a solution containing adenine, guanine, cytosine and uracil, optical densities are measured at 4 different wave lengths both at pH 1 and pH 13, and the amount of each base can be calculated by making use of the proper optical density differences. This method is simpler in procedure in comparison with other methods. Its reproducibility is satisfactory and the recovery falls within the range of 94-106%.

1.拟定了测定稻田土壤沉降系数的方法。取相当于风干土100克的原状土,加水搅匀后,置1,000毫升量筒中,加水至刻度,用搅拌棒以每分钟上下40次的速度搅拌1分钟,静置。观测开始出现浑水与土粒分界时,下层土壤容积的毫升数(A),及静置24小时下层土壤容积的毫升数(B),二者的比值称为沉降系数(C),以此作为结构状况的标志。其计算式如下:C=B/A。2.沉降系数与土壤有机质的质量有密切关系,土壤中的胡敏酸,其分子较复杂,土壤的沉降系数也较大。机械组成似对沉降系数值影响不大。3.沉降系数值(C)在1以下时,数值的大小与土壤耕性的好坏趋势一致,数值大,表示土壤耕性好;C 值在1以上时,表明土壤的起浆性强。4.水旱轮作利用方式下的水稻土,其沉降系数值恒较双季稻连作利用方式下者大,前者中的还原性物质量较少,NH_4~+-N 及速效磷量较多。冬浸田与冬种田比较,前者的沉降系数值较后者为小,还原性物质较多,速效性养分含量较低。

The chemical te ting technique of liquid flo measurement by brine concentration method is described in this paper.

The alue of (c-a)is calcula■el from (■+1)(b-a), and then regie ■(c-a)■ith(b-a), we can obtain the line■eg■ession equation with the inte cept A and the ■l pe B, viz (c-a)'=A+B(b-a). Subsequen■ly, the value b of Ag O_3 solution required for the mix ure of the unknown fold number of dilution is determined, and the value of(b-a)is substiiuted into the regression equation just obtained to calculate the value (c-a)'. We can calculate the fold number of dilution of the mixture by (c-a)'/(b-a).The fold number of dilution determined by this technique is very accurate, and the calculation of the fold number of dilution is quick by using a rcientific ca■calator. As soon as the flow of injection liquid (q) is measured, the total flow of pimp (Q_p) can be ca culated by (R+1)'q.

本文介绍了用食盐浓度法测流的化学测试技术,方法是取已知稀释倍数(R+)的一定体积的标准混合液,并测出完全沉淀Cl~-所需AgNO_3溶液的毫升数b,再测出原水所需的AgNO_3毫升数(a),由(R+1)(b-a)求出(c-a),将(c-a)同(b-a)进行回归,得到具有截距为A和斜率为B的回归方程,即(c-a)′=A+B(b-a)。然后,把未知稀释倍数的混合液所需的A NO_3的b值测出来,并将(b-a)值代入得到的回归方程求出(c-a)′值,用(c-a)′/(b-a)即可求出该混合液的稀释倍数。本技术测得的稀释倍数相当准确,用科学计算器可迅速计算出稀释倍数。注入液的流量一经测出即可用(R+1)′q计算出泵的总流量(QP)。
