One of the ways to raise the efficiency and diminish local overheating is by the using of shields to decrease the stray losses produced in the stator core end-plates or rotor surface of an electrical machine due to the rotating magnetic fields. However, as has been indicated in the papers by several writers, positive effects of shielding are not always realized; that is to say, the stray losses may even increase if the material or thickness of the shield is not properly chosen. In this paper, theoretical analysis...

One of the ways to raise the efficiency and diminish local overheating is by the using of shields to decrease the stray losses produced in the stator core end-plates or rotor surface of an electrical machine due to the rotating magnetic fields. However, as has been indicated in the papers by several writers, positive effects of shielding are not always realized; that is to say, the stray losses may even increase if the material or thickness of the shield is not properly chosen. In this paper, theoretical analysis of the losses in multilayer media in the rotating fields is made, a formula for the calculation of the stray losses in machines with shields is derived from this theoretical analysis based on the Maxwell's equations and curves are drawn. Finally a primary field coefficient Kp, so named by the authors, is given so as to facilitate the proper designing of the shields.. Experiments on a model have been carried out and the results obtained agreed with the analytical study.

利用屏幕以减少电机定子端部压板损耗或转子表面损耗是提高电机效率及减轻局部过热现象的措施之一。但在屏幕层的材料及厚度选用得不合适时,也有可能增加损耗。本文进行了旋转磁场中多层媒介质的损耗的理论分析,从马克士威方程推导出有屏幕时的损耗计算公式,文章最后提出了“原磁场系数”Κρ作为对选择适当的屏幕材料及厚度以减少某次谐波的损耗的判据。 计算公式的结果与从模型实验上所得的结果是相符的。

A primary study was made on the effects of some environmental factors in relation to the process of photosynthesis of different varieties of Chinese cabbages (including Brassica chinensis and B. pekinensis) for finding out the physiological bases to increase their yield and quality.

在白菜光合作用的试验中发现白菜的光合强度水平不高。各种白菜及其品种的光合强度与叶绿素含量有显著的正相关。白菜在生长过程中各个时期的光合强度不同:幼苗期最低,莲座期增高,结球期最高。温度对光合作用有显著的影响。植株中下层叶片对较弱的光照强.度有适应力。一日间的光合强度依温度和光照强度而变迁,在水分充足的情况下,蒸腾强度对光合强度无显著的影响,但叶子萎蔫使光合强度显著降低。用含氮肥料的溶液进行根外追肥能显著地提高光合强度。

The electromyographies were made on 12 healthy young adult males to investigate the function of supinators and pronators in the extended and flexed elbows during pro- nation and supination.The potentials were picked up with the needle electrode from the pronator teres,pronator quadratus,the supinator,the biceps brachialis and the bra- chioradialis.The study revealed the following facts: 1.During slow pronation,regardless whether the elbow was flexed or extended, the potentials from the pronator quadratus were always more active than that from the pronator teres.The former showed the activities from “marked” to “most marked” and the latter from “slight” to “moderate”.When the pronation was resisted,the activities increased in both muscles. 2.During slow supination,both pronators showed activities of various degree as antagonistic muscles.During slow supination in the extended elbow,the potentials ap- peared in the supinator alone,but no activities were seen in the biceps unless the supina- tion was resisted.The biceps was,therefore,not proved to be a supinator when the elbow was in an extending position.When the flexed elbow was supinated from a prone position,the activities were recorded from the supinator immediately but none from the biceps at first.When the forearm reached an intermediate position,it began to show “slight” activity whereas the supinator showed “marked”.When the forearm moved to- ward full supination the activities of the supinator decreased gradually,reaching “no activity” at the end,but the activities of the biceps increased gradually.It was proved that the supinator was a primary supinator and the biceps a reinforcer. 3.The brachioradialis is usually described as a pronator when the forearm is in supine position and a supinator in prone position.This present study showed it was neither a pronator nor a supinator in the extended forearm,and it was only so when supinating a flexed forearm from a prone to semiprone position.In the further course of supination the activities were not increased at all.Thus the brachioradialis could be considered as an axillary supinator from prone to semiprone position.

本文在12个健康男性青年的旋前方肌、旋前圆肌、旋后肌、肱二头肌及肱桡肌,以Ediswan脑电墨水描记仪,用肌内电极引出电位进行分析,结果认为:旋前方肌无论在肘的伸位或屈位,当前臂慢旋前时,它的电位都比旋前圆肌更活动。给以抵抗力时二肌电位活动都增加。旋后肌在肘伸位前臂慢旋后时,即出现了电位活动,但肱二头肌无活动只是给以抵抗力时始出现电位活动。肘屈位,前臂从旋前位旋后时,旋后肌首先出现电位活动。肱二头肌自中间位到完全旋后位电位活动逐渐增加,而旋后肌则逐减小。肱桡肌使旋前位或旋后位的前臂迴旋到中间位的作用,只是在肘屈位特别自旋前位旋后至中间位的电位较明显。
