A steady-state,direct-current high-pressure CH4-H2 glow discharge in a cup-shaped cathode parallel to anode configuration is investigated by using their V-I characteristics and CCD images.The discharges display an abnormal glow feature,and an expansion of a negative glow is observed on the cathode sidewall with the increasing discharge current.There exists a dependence of voltage on gas pressure for different fixed currents.The voltage decreases with gas pressure initially,and then increases conversely,which is correlated with the glow states of the cathode sidewall.This study exhibits a self-adjusting characterization for plasmas in cathode fall,which is important for maintaining steady-state,abnormal glow discharge in a relatively high pressure range.

游戏是幼儿教育的重要内容与形式，对幼儿的身心发展具有深远的意义。因此，在幼儿教育教学活动中，教师应通过游戏引导幼儿动口、动手、动脑，发展幼儿的语言能力、操作技能、创造性思维能力等，从而促进幼儿发展。 爱玩是孩子的天性，游戏能使儿童获得愉悦和满足感，因此，在幼儿园开展游戏活动，不仅可以有效提高教学质量、开发幼儿智力，还能提高幼儿身体素质，促进幼儿德智体美全面发展。 一、促进幼儿智力发展 我国著
