采用微波加热干燥技术测定燃烧中全水分质量分数，其目的是利用微波加热具有的热效率高、加热时间短等优点，快速测定出燃烧中全水分质量分数。此法既缩短了加热时间，又减少了能量消耗，是一种快速、有效的加热干燥方法。微波加热是一种内部加热过程，高频微波在腔内形成一个 The microwave heating and drying technology is used to determine the mass fraction of total moisture in combustion. The purpose of this method is to rapidly determine the mass fraction of total water in combustion by utilizing the advantages of high thermal efficiency and short heating time of microwave heating. This method not only shorten the heating time, but also reduce energy consumption, is a fast and effective method of heating and drying. Microwave heating is an internal heating process, and high frequency microwaves form one in the cavity
