计算机使用一段时间以后,主机内部部件的表面便会蒙上一层灰尘,其危害性主要表现在以下几个方面: (1)在有一定的空气湿度的条件下。电脑主板上由于多年未清洁维护而灰尘过多,降低了电子元件的绝缘性.造成元件被击穿、短路等故障。 (2)CPU风扇及散热器蒙上灰尘,散热性能变差、噪音变大,使电脑不知原因的死机次数增多。 (3)光驱的选盘能力下降。 (4)键盘按键不灵敏。 所以电脑的清洁维护是十分重要的。对主机和外设的外壳应每天擦拭一次,用干净的毛巾擦去灰尘即
After the computer is used for a period of time, the surface of the internal components of the host will be covered with dust. Its harmfulness mainly manifests in the following aspects: (1) Under certain air humidity conditions. Computer motherboard due to many years of unclean maintenance and excessive dust, reducing the insulation of electronic components. As a result of components breakdown, short circuit and other failures. (2) CPU fan and radiator dust, thermal deterioration, noise, so that the number of computer crashes for an unknown reason increased. (3) optical disc drive ability to decline. (4) keyboard keys are not sensitive. Therefore, the computer cleaning and maintenance is very important. The shell of the host and peripherals should be wiped once a day, wipe the dust with a clean towel that is
