一、问题提出海水温度是一个重要的海洋环境因子,目前观测海水温度所采用的仪器发展很快,如测温链能提供温度随深度变化的连续剖面;电子温盐深仪能用电子加工的形式记录、储存、传送资料,照相温度计能提供实时的记录;抛弃式深度温度计不需要船只停航进行水温观测等,说明水温仪器正向电子、摇控、连续、自记的方向发展。然而采用颠倒温度表测温,它的优点是精度比较高,可达±0.01℃,仪器稳定可靠,记录方式简单等,目前在海洋环境调 First, the issue raised the sea water temperature is an important marine environmental factors, the current observation of sea water temperature instruments used in the rapid development, such as the temperature can provide temperature changes with depth continuous cross-section; electronic temperature salinity instrument can be used electron processing Record, store and transmit data, and the photographic thermometer can provide real-time record. The disposable depth thermometer does not need the vessel to suspend the water temperature observation, etc., indicating that the water temperature instrument is developing in the direction of electronic, remote control and continuous recording. However, the use of inverted temperature thermometer, which has the advantage of higher accuracy, up to ± 0.01 ℃, the instrument is stable and reliable, the recording method is simple, etc., currently in the marine environment
