普通表示温度年变化,常以月为单位,本文则以候为单位,全年分七十三候,每候五日。盖欲藉此以觇我国各地全年温度变化递嬗之足迹,较之以月平均表示者,更求精详耳。所惜中国测候事业,近十年来始渐发达,历史较久之纪录,除海关测候所及外人代设之气象机关外,渺不可得。且此等纪录,大抵集中於沿江沿海之地带,故欲持此而论全国之温度变化,似有杯水车薪之感。惟全国各地有较详而较久之纪城可资本文研究者,亦达三十余处之多,故虽不能谓详尽无遗,亦足以由此窥其堂奥矣。 Ordinary that the temperature changes, often in months, this article is to wait for the unit, the year is divided into seventy-three wait, every five days. Cover to take this 各 around the country throughout the year temperature changes in the footsteps of the evolution, compared with the average monthly expression, but also more precise ear. Unfortunately, the Chinese survey service, which has been gradually developed in the past decade and has a long history, can not be obtained except for the customs offices and the meteorological offices set up by foreigners. These records are mostly concentrated in the coastal areas along the river. Therefore, the temperature change in the whole country seems to be a factor in the drop in the bucket. However, there are more than 30 prefectural and capitalist researchers in various parts of the country. Although they can not be exhaustively exhaustive, they are enough to glimpse them.
