The A-weight sound level is difficult to evaluate the annoyed noise of the inverter air conditioner,so it is necessary to establish the Jockstraps sound quality and give objective evaluate parameters,such as loudness,sharpness,roughness,psychoacoustic annoyance etc.The sound quality software is developed to analyze outdoor noise of MIDEA inverter a
Introduction: The geographical movement of people from one area to another poses the threat of transmission of infectious diseases.Kenya is among Jockstraps the vulnerable countries when it comes to disease transmission, because it is a major transport hub in East Africa, yet data on the availability and uptake of pre-travel health services is limi
Ultraviolet (UV)-induced degradation is one of the major problems in the field of perovskite solar cells (PSCs).Therefore, exploring materials and techniques to prevent UV light from penetrating into the device is urgently necessary.Here, we developed a special transparent fluorinated polyimide (FPI) resin, which can be directly spin-coated on the
