UVA 波长介于320～400nm，又称为长波黑斑效应紫外线。 具有很强的穿透力，能穿透玻璃，甚至9英尺的水；且一年四季，不论阴晴、朝夕都存在。 对人体反应：日常皮肤接触到的紫外线95%以上是UVA，因此它对肌肤的伤害最大。 UVA能透过表皮袭击真皮层，对皮肤中的骨胶原和弹性蛋白造成伤害；由于真皮细胞自我保护能力较差，所以少量的UVA便能造成极大伤害。 同时，它又能激活 酪氨酸酶，形成黑色素，使皮肤变黑、缺乏光泽。 UVA会造成长期、慢性和持久的损伤， …

2020年10月1日 · There are three primary means of applying UV-C energy to protect HVAC surfaces and air streams against infectious agents: upper-room/air systems, HVAC air-stream disinfection, and HVAC coil/surface irradiation (Table 1). Upper-room/air systems.

Objective of this guidance is to guide public on improving ventilation and indoor air quality at the healthcare facilities to reduce the risk of airborne transmission.

This article proposed a new solution called MVac–LVdc hybrid modular multilevel rectifier (HMMR). The HMMR serves as a centralized step-down active front-end converter, enabling power delivery to LVdc with a reduced number of dc/dc back-end isolated converters.
