浴缸也不宜太大,以实用为主,这是在购买之前就要仔细考虑的问题。卫浴间灯具接头忌暴露在外卫浴间比较潮湿,所以在安装电灯、电线时要格外小心。灯具和开关使用带有安全防护功能的,接头和插座也不能暴露在外。开关如为跷板式的,宜设于卫浴间门外,否则应采用防潮防水型面板,以防止因潮湿漏电造成的意外事故。卫浴间忌杂乱杂乱是浴室风水的大忌,这样会使空气滞碍难行。只放置限度的必需品,不宜将过多杂物放在卫浴空间,清扫用具不宜露在外面,应有专门的收纳。

3)从开关变压器的一次电路结构来看,有分立元件构成的和集成振荡芯片构成的两种电路形式。因而从振荡信号的来源看,又分为自激(分立零件)和他激式(IC电路)开关电源。两种电路结构都有应用。
4)开关管有采用双极型器件和采用场效应晶体管的。
5)小功率变频器采用单端正激式电路,大、中功率变频器常采用双端正激式电路。一般变频器的开关电源,常提供以下几种电压输出:CPU及附属电路、控制电路、操作显示面板的+5V供电;电流、电压、温度等故障检测电路、控制电路的±15V供电;控制端子、工作继电器线圈的24V供电。四路相互隔离的约为22V的驱动电路的供电,该四路供电往往又经稳压电路处理成+15V、 -7.5V的正、负电源供驱动电路,为IG逆变输出电路提供激励电流。

同时可消除分布在晶界上微量杂质的有害作用,起着强化和稳定模具型腔表面晶界的作用。另外,稀土元素与钢中的有害元素发生作用,生成高熔点化合物,又可这些有害元素在晶界上偏聚,从而降低深层的脆性等。在压铸模具表面强化处理工艺中加入稀土元素成分,能够明显提高各种渗入法的渗层厚度、提高表面硬度,同时使得渗层组织细小弥散、硬度梯度下降,从而使得模具的耐磨性、抗冷、热疲劳性能等显著提高,从而大幅度提高模具寿命。
