In chronical experiments on dogs provided with gastric pouches, we showed that the gastric secretion stimulated by histamine can be reflexly inhibited by electrical stimulation on the skin. This inhibition can be shown with Heidenhain pouches as well as with Pavlov pouches, indicating that the phenomenon does not depend on an intact vagus innervation. Furthermore it can still appear in Heidenhain pouches after bilateral subdiaphragmatic section of the splanchnic nerves and bilateral extirpation of the solar...

In chronical experiments on dogs provided with gastric pouches, we showed that the gastric secretion stimulated by histamine can be reflexly inhibited by electrical stimulation on the skin. This inhibition can be shown with Heidenhain pouches as well as with Pavlov pouches, indicating that the phenomenon does not depend on an intact vagus innervation. Furthermore it can still appear in Heidenhain pouches after bilateral subdiaphragmatic section of the splanchnic nerves and bilateral extirpation of the solar plexuses. In such dogs the adrenal glands are of course also severed from their external nerve supplies. It thus follows that the sympathetic innervation to the stomach and the adrenal glands are not indispensable either. Apparently there is some humoral factor as yet unknown, which inhibits gastric secretion and which can be reflexly mobilized by such means as electrical stimulation of the skin. On the other hand, we were able to show that both direct electrical stimulation of the splanchnic nerve and intravenous injection of adrenaline can inhibit the gastric secretion stimulated by histamine. This suggests that when the sympathetico-adrenal system is intact it is likely to be also involved in the inhibitory phenomenon under consideration. The phenomenon is evidently a complex one involving both nervous and humoral factors, and we had also shown that it requires the participation of higher nervous centres, being not elicitable in anesthetized animals. We wish to express our deep gratitude to Prof. T. P. Feng for suggesting this problem and for constant guidance throughout this work.

(一)在慢性實驗中用備有小胃的狗,我們证明組織胺引起的胃分泌能反射地为皮膚電刺激及一些其他外界刺激所抑制。 (二)這抑制現象在除去胃的迷走神經支配相交或神經支配,並隔離腎上腺的神經聯系時,仍能出現。它似有某種可以反射地形成的抑制性體液變化為基礎。 (三)但在急性實驗中我們又證明大內臟神經和注射腎上腺素均能抑制組織胺引起的胃分泌,這指示在正常動物胃分泌的反射抑制仍可能通過交感神經-腎上腺系統而得實現。 (四)本文所述的胃分泌的反射抑制現象顯然包含複雜的神經-體液機制,並且是在高級神經中樞參加下產生的。

The only previous work known to us on the polaron problem in atomic lattices gives a result which would mean that polarons of the adiabatic type (in the first approximation, a self-trapping state with static deformation) should exist in crystals such as Ge and Si. (The method used in dealing with the elastic energy is shown to be in error.) We have reconsidered the problem and found that most probably the reverse is the case. The problem is then investigated on the basis of the perturbation...

The only previous work known to us on the polaron problem in atomic lattices gives a result which would mean that polarons of the adiabatic type (in the first approximation, a self-trapping state with static deformation) should exist in crystals such as Ge and Si. (The method used in dealing with the elastic energy is shown to be in error.) We have reconsidered the problem and found that most probably the reverse is the case. The problem is then investigated on the basis of the perturbation theory. It is shown that the volume change, strongest at the electron, extends essentially as far as one de Broglie wave length of an electron moving with the speed of sound; beyond this distance, the elastic displacement is of the 1/r~2 type. The volume change

乾根—别卡曾经分析过原子晶体中的极化子问题。文中指出,其中弹性形变的考虑是不正确的,而且“绝热型”的极化子,在例如Ge,Si等原子晶体中存在的可能性是十分微小的。以微扰论为基础的计算证明,电子引起的局部体积变化发生在半径≈λ的范围内,λ是以声速运动的电子的德布罗意波长。局部体变的数值等於E/(α+4/3μ)(E为形变势常数,α和μ分别为体变和切变模量)。局部体变还在样品中引起一个均匀的形变,两者合起来使样品体积改变E/α。具体的分析证明,在类氢的杂质能级中的电子使样品体积产生同样的体积变化。这个效应是相当大的;例如,在Ge和Si这样的晶体中,效应甚至可以舆实验所观测到Ⅲ,Ⅴ族杂质原子的体积效应相比拟。 导带中低速电子能量的改变约等於 (电子质量/原胞质量)(E/(k_D))E;在Ge晶体中,如果E=1—10电子伏,能量改变是0.001—0.1电子伏。相应的有效质量改变是1/1000—1/10电子质量。在类氢杂质能级中,电子能量改变远比上值为小;理论上电子—晶格互作用有着可能致使类氢能级自发电离。

Flooding of streets and premises in the city districts of Shanghai has been responsible for heavy losses incurred in industrial operations, materials stored in ware-houses, local communication, and the dwellings of many inhabitants. In this paper, the writer has made a study of the various factors contributing to the phenomenon of flooding in Shanghai, and has also carefully analysed the whole situation. Besides, the writer has also made certain proposals as a remedy for the evil, including the collection of data for making further investigations of the problem and some measures in connection with the improvement and re-modelling of the storm-water sewer system of Shanghai.
