目的:1.故障一故障现象:相机频繁报卡片错误.故障分析:根据操作面板提示将相机上盖板打开,胶片卡在密度计入口,将胶片拿开,reset相机,故障依旧.观察发现卡片时胶片前沿上卷,而且热显影鼓转动时有异常声音,分析可能是热显影鼓转动不顺畅,造成热显影时间过长导致胶片卷曲.故障排除:更换热显影驱动皮带及皮带轮后,故障排除.
目的:1.故障一故障现象:开机时显示系统无显示.故障分析与检修:检查发现CR950系统的散热风扇停止工作,打开设备右侧的机盖,发现激光管也停止工作,考虑到显示器、散热风扇和激光管部分同时损坏的几率较小,估计散热风扇及激光管停止工作的原因,是电源供电故障所致.打开机器后盖,找到开关电源,此电源有2组输出,分别是12、24V,用万用表测得交流电压输入正常,但无直流12、24 V电压输出,判定故障出白此
Background: Inhibition of histone deacetylases (HDAC) results in attenuated development of hypertension in DOCA-induced hypertensive rats and spontaneously hypertensive rats.However, the molecular mec
Aim: To investigate the effects of DL0805, a Rho kinase inhibitor, on the vasoconstriction activity induced by angiotensin Ⅱ (Ang Ⅱ) in the rat thoracic aortic rings and to explore its vasodilative me
Aim: The purpose of this study was to determine the effects of SCU on vascular endothelium dependent relaxation injury induced by ischemia reperfusion (IR) and the underlying mechanisms.Methods: Rat m
Aim: Inhibition of Rho-kinase displays vasodilation property although its effect on cardiac remodeling in heart against pressure overload and ischemia has not been fully elucidated.The present study w
Aim: Diabetic individuals gain high levels of methylglyoxal (MGO) and advanced glycation end-products (AGEs) which plays an important role in diabetic vascular complications, such as stroke.Our previo
Aim: Our past research has shown that transient limb ischemia can induce remote late preconditioning that protects the myocardium from ischemia/reperfusion (I/R).In this study, we further tested if la
Aim: Ligustrazine is a monomer extracted from the Chinese herb Chuan Qiong.In this study, we examined the protective effect of Ligustrazine on adriamycin (ADR)-induced acute heart failure (AHF) and un
Aim: To examine the effect of Osthole on vascular remodeling in balloon-injured rats and explore its possible mechanisms.Methods: After balloon-injured carotid artery of rats model was established, an
