海明威的自卑情结及其在创作中的治疗

海明威由于在爱情、创作及生活环境等方面的劣势而产生自卑情结，作家的这种自卑情结积聚起来，注入他的创作，使他的各种焦虑和紧张以及无法满足的欲望都在创作中借助幻想的艺术世界得以发泄。小说创作及其相关主题的发生，在一定程度上对作者的自卑起着治疗和宣泄作用。

氯化钙复合吸附剂制冷性能的实验研究

研究与开发对环境友好的吸附式制冷工质对对节能和环保都具有重要意义.本文对以CaCl2为吸附剂,NH3为制冷剂所组成的吸附式制冷工质对的吸附性能进行了研究.针对CaCl2吸附剂颗粒强度不高、长期使用后易出现膨胀粉化、传热传质性能下降等问题,将 CaCl2分别与CaSO4、水泥按质量比4:1进行复配,并进行吸附制冷性能实验.实验表明：温度是过程的控制因素,在110℃时,CaCl2/CaSO4复合吸附剂的单位脱胶凝剂基吸附剂制冷量是CaCl2的1.325倍,是CaCl2/水泥的1.89倍.对吸附剂比表面积及孔结构表征的结果为：CaCl2 、CaCl2/CaSO4的BET比表面积分别为1.2871m2.g-1,1.9163m2.g-1;总孔容分别为0.005117cm3.g-1,0.007703cm3.g-1;平均孔径分别为8.420nm,11.521nm.实验结果表明：复合吸附剂的制冷量有较大提高、膨胀粉化程度降低、其微孔结构和比表面积保持良好.     

Effects of pCai and pHi on cell-to-cell coupling

Summary Internal longitudinal resistance (r_i), a determinant of cardiac conduction, is affected by changes in intracellular calcium and protons. However, the role and mechanism by which H⁺ and Ca²⁺ may modulate r_i is uncertain. Cable analysis was performed in cardiac Purkinje fibers to measure r_i during various interventions. In some experiments, intracellular pH (pH_i) was recorded simultaneously to study the pH_i-r_i relation. Both intracellular Ca²⁺ and H⁺ independently modified r_i. However, internal resistance of cardiac fibers was insensitive to pH_i changes compared to other tissues. A latent period preceded the pH_i-related changes in r_i and the amount of change depended upon methodology. The results suggest that direct action of protons on r_i may be subordinate to other regulatory processes. Ionic regulation of internal longitudinal resistance may occur by more than one mechanism: i) direct cationic binding to sites on junctional membrane proteins; and ii) H⁺- or Ca²⁺-dependent phosphorylation of junctional proteins.
