露点温度是一个非常重要的气象要素,在很多教科书中只简单地给出了它的定义,即“当空气中的水汽含量不变且气压一定时,通过降低气温,使空气中的水汽达到饱和时的温度称为露点温度,简称露点。它的单位与温度一样,用℃表示。气压_一定时,空气中的水汽含量多,露点高;反之,露点低”。如果教师仅仅这样简单地把露点温度的定义灌输给学生的话,他们会感到非常难以理解和掌握,学生自然地会提出这样的疑问:为什么在露点温度的定义中要限定水汽含量和气压不变?它的单位既然与温度相同,为什
Dew point temperature is a very important meteorological element, and in many textbooks it is simply given its definition, that is, “when the water vapor content in the air is constant and the pressure is fixed, by lowering the temperature, the water vapor in the air reaches Saturated temperature is called the dew point temperature, referred to as the dew point.Its unit and the temperature, with ℃ said.Pressure _ a certain time, the air moisture content, dew point high; the other hand, the dew point low ”. If teachers simply instill in their students the definition of dew point temperature in such a simple way, they find it very difficult to understand and master. Students naturally ask the question, “Why does the definition of dew point limit water vapor and air pressure?” Since its unit with the same temperature, why
