含葡萄糖培养基高温灭菌变色及其防范措施的研究

研究了葡萄糖浓度、pH值、硫酸铵及氨基酸对葡萄糖溶液高温变色的影响，结果表明pH值是葡萄糖溶液高温变色的主要因素；pH值低于5.5，并且避免与含氨离子化合物共同灭菌，可以有效防止色素的产生。     

新型数字电液比例系统在大中型装载机中的应用

通常大中型装载机液压系统中采用的多路换向阀存在换向操纵力大、响应速度慢、重复误差大等诸多缺点。本文提出了采用数字高速开关阀为先导阀的新型数字电液比例系统的控制方式，当有一定脉宽占空比的信号后，数字高速开关阀动作，主阀控制口可得到与占空比成比例的控制压力，从而控制多路阀主阀芯位移和换向，实现工作装置运动速度及方向控制。

Control of locomotion in the marine mollusc Clione limacina. XI. Effects of serotonin

The locomotor activity in the marine mollusc Clione limacina has been found to be strongly excited by serotonergic mechanisms. In the present study putative serotonergic cerebropedal neurons were recorded simultaneously with pedal locomotor motoneurons and interneurons. Stimulation of serotonergic neurons produced acceleration of the locomotor rhythm and strengthening of motoneuron discharges. These effects were accompanied by depolarization of motoneurons, while depolarization of the generator interneurons was considerably lower (if it occurred at all). Effects of serotonin application on isolated locomotor and non-locomotor pedal neurons were studied. Serotonin (5 x 10(-7) to 1 x 10(-6) M) affected most pedal neurons. All locomotor neurons were excited by serotonin. This suggests that serotonergic command neurons exert direct influence on locomotor neurons. Effects of serotonin on nonlocomotor neurons were diverse, most neurons being inhibited by serotonin. Some effects of serotonin on locomotor neurons could not be reproduced by neuron depolarization. This suggests that, along with depolarization, serotonin modulates voltage-sensitive membrane properties of the neurons. As a result, serotonin promotes the endogenous rhythmical activity in neurons of the C. limacina locomotor central pattern generator.
