本文介绍了一种适用于农田、温室、森林、山地等小气侯研究的 DYZ—1型遥测多点温湿度仪的原理、设计、性能及其田间使用效果。其设计方案是经计算机选优而得,具有较高的精度。在-25～50℃、20～100%RH 范围内,温度标准差为0.1℃、湿度标准差为1%.该仪器在野外使用,经受了高温(36.9℃)高湿(99%)的考验,仪器运转正常、性能可靠.在北京(温带)、南京(亚热带)、海南岛(热带)三种不同气侯带与阿斯曼通风干湿表在田间进行对比实验,包括各种(辐射、观测等)误差在内,在5～36.9℃、19～99%RH 范围内,温度标准差为0.23℃,湿度标准差为1.7%。
This paper introduces the principle, design, performance and field effect of DYZ-1 telemetry multi-point temperature and humidity instrument which is suitable for the study of microclimate in farmland, greenhouse, forest and mountainous area. Its design is selected by the computer derived, with high accuracy. The standard deviation of temperature is 0.1 ° C and the standard deviation of humidity is 1% in the range of -25 to 50 ° C and 20 to 100% RH. The instrument is used in the field and has undergone the test of high temperature (36.9 ° C) and high humidity (99%) , The instrument is in normal operation and the performance is reliable.Comparative experiments were conducted in the field with three different climatic zones: Beijing (temperate), Nanjing (subtropical) and Hainan (tropical) Observation, etc.) error, the standard deviation of temperature is 0.23 ℃ and the standard deviation of humidity is 1.7% in the range of 5 ~ 36.9 ℃ and 19 ~ 99% RH.
