However, not significant relationships were found between soil respiration and soil moistures at 5 cm depth in all study plots. Soil temperature and moisture together could explain changes in soil respiration of 75.2% and 93.7%, and 90.0% and 92.8% in litter exclusion and addition plots in the Liquidambar formosana and Cinnamomum camphora forests, respectively.

两种群落去除和添加凋落物土壤呼吸的季节变化均与5 cm土壤温度呈显著指数相关（P﹤0.001），与5 cm土壤湿度相关性不显著（P＞0.05）；土壤温度和湿度可以共同解释去除和添加凋落物后土壤呼吸变化的95.2%、93.7%和90.0%、92.8%。

Al2O3 moisture sensor is a new type water sensor, which can measure minim water.

文摘：氧化铝湿度传感器是一种新型的测量微量水分的传感器，在物料干燥和环境湿度监测中都具有重要的应用。

As far as the design of the hardware is concerned, here chose the S302H5V5 capacitive humidity sensor as the humidity sensor, ADC0809 as the A/D conversion, the touching style key as the keyboard, LCD as the monitor display. The out port circuit is consists of triode, NOR gate, relay, light-emitting diode and so on.

硬件方面，土壤周围湿度的测量采用先进的S302H5V5电容式湿度传感器，信号采集的A/D转换模块采用了ADC0809芯片；键盘、显示分别采用了点触式按键和LCD显示；输出控制电路由三极管、或非门、继电器、发光二极管等组成。

Firstly, we study how the ensemble number, surface soil moisture observational error and model error impact on the results.

第四章研究了集合平方根滤波同化方法利用表层土壤湿度观测反演深层土壤湿度信息的能力。

The results show that after one and two hour irrigation, soil moisture is a three order polynomial of the soil depth. Soil moisture in deep layers can be got from the top-layer results according to this relationship.

结果表明：在注水1，2h，土壤湿度随土壤深度呈3次多项式关系变化，可以根据浅层土壤信息反演深层土壤湿度。

At that temperature. Varying concentrations of sulfate acid were tested as humidity control agents at 5-35℃, with each yielding a stable humidity in the perspex chamber regardless of temperature.
