Self-recording system is devised and used to measure potential gradient at Yenching. In fine weather the results show two maxima and two minima for a whole day. During raining potential gradient is constant at zero value, except when lightening and thunderstorm occur in which case the potential gradient changes rapidly both in magnitude and direction.

本篇所述,为在北平燕京大学用静电计及一连续记录器测量大气电位梯度之方法及结果测量方法,乃用一种均位器(eqalizer)将离地面约3至6米高之电位显示于静电计上再用照相纸将此电位制成连续记录。测量所得结果如下:晴天之电位梯度。一日之中,有二最高值及二最低值雨时梯度即降至零,且此值非至雨止不变。当闪电及雷飓时,梯度之方向与值,变易极速。且较晴天时为大。

The present work extends the obserwtion of an earlier report and Shows that the conduction block in nerve produced by cocaine, procaine, urethane, isotonic choline chloride, TEPP and DFP, though not accompanied by any lowering of membrane potential, can be relieved by anodal current. It follows that the mechanism of anodal relief of block can not be supposed to be simply a restoration of previously lowered membrane potential.

The present work extends the obserwtion of an earlier report and Shows that the conduction block in nerve produced by cocaine, procaine, urethane, isotonic choline chloride, TEPP and DFP, though not accompanied by any lowering of membrane potential, can be relieved by anodal current. It follows that the mechanism of anodal relief of block can not be supposed to be simply a restoration of previously lowered membrane potential. With eserine, although depolarization occurs, the block develops. long before, the start of the depolarization; thus the anodal relief of the block produced by eserine likewise cannot be simply due to a restoration of polarization. Successful anodal relief of block somehow depends upon the initial state of the nerve. For instance, it is better in a freshly dissected nerve than in a nerve after several hours soaking in Ringer; better in a nerve having had prolonged soaking in Ringer with somewhat raised potassium concentration than in a potassium-free Ringer. It seems that any prior treatment causing a decrease of the potassium content of the nerve, tends to make anodal current less effective in relieving conduction block.

本文研究可卡因、普魯卡因、氨甲酸乙酯、氯化膽鹼、依色林、TEPP及DFP在兩棲類神經所產生的傳導阻遏。上述各種傳導阻遏的特點,是或者根本沒有膜電位的降低与之相伴,或者膜電位的降低發生在傳導阻遏之後。但是在一定條件下,陽極電流對於這些傳導阻遏都有解除作用。陽極電流對上述由於可卡因、普魯卡因、氨甲酸乙酯及氯化膽鹼所產生傅導阻遏的解除效應,與神經原來的狀態有关。一般地說,凡試驗前的預先處理,有減低神經鉀含量的影響者,亦有使陽極電流的解除效應減弱的傾向。

The molecular weight determination of polycaprolactam by the end-group titration was studied with conductometric, potentiometric and visual methods. Both amino and carboxyl end-groups could be titrated in the same solvent at the same temperature. The sample was dissolved in benzyl alcohol at about 135°, cooled to 60°, and then diluted with suitable amount of methanol-water mixture (2:1 by volume). The supersaturated solution thus formed, which could remain clear over several hours, was titrated with 0.03 N alcohol-water...

The molecular weight determination of polycaprolactam by the end-group titration was studied with conductometric, potentiometric and visual methods. Both amino and carboxyl end-groups could be titrated in the same solvent at the same temperature. The sample was dissolved in benzyl alcohol at about 135°, cooled to 60°, and then diluted with suitable amount of methanol-water mixture (2:1 by volume). The supersaturated solution thus formed, which could remain clear over several hours, was titrated with 0.03 N alcohol-water solution of hydrochloric acid and of sodium hydroxide. Small amount of formaldehyde should be added before carrying out carboxylgroup titration. The reagents were standardized against 6-amino-caproic acid as primary standard. Both conductometric and potentiometric methods gave satisfactory titration curves, and amino and carboxyl groups could be titrated successively in the same solution. The indicators used in visual titrations were bromophenol blue for amino-group and phenolphthalen-thymol blue (6:1) for carboxyl-group. Sharp color changes at end-points were observed.The number average molecular weights obtained for three polymer samples by either aminogroup titration or carboxyl-group titration with these three methods were in good agreement. But the molecular weights obtained from amino-group titration were higher than those from carboxylgroup titration in all cases.

聚已内醯胺的端基滴定测定分子量,可以用同一溶剂[苯甲醇,甲醇-水(2:1)混合溶剂],在同一温度(室温)时用電導、電位或指示剂法分别先後进行氨基和羧基的滴定。滴定剂用标准盐酸和氢氧化鉀的甲醇-水溶液(约0.03N),電導法及電位法滴定羧基時另加甲醛抑制氨基,所得滴定曲线良好。指示剂法的终點均清晰。三法分别自氨基或羧基测得的聚合物数均分子量相互一致。确立了用这三种方法进行端基滴定的可靠性。但是同一试样自氨基测得的分子量,一般均高於自羧基测得的分子量。
