Lapse rate and analysis of relation between derived data and field data arc used to determine the coefficient in correction.

订正前后土壤湿度结果的对比分析表明，进行订正后的TVDI能更好地反演土壤湿度。

Will cut the half lignification branch below grow 8 - 10 centimeters, thing 2 - 3 outside the bine of the section paragraph, in the slotting machine that sand of river of stick of a short slender pointed piece of metal or pearlite develop, maintain certain matrix humidity and air humidity, notice shady.

将剪下的半木质化枝条剪成长8－10厘米。事2－3外节的茎段，扦插于河沙或珍珠岩培养的插床中，保持一定的基质湿度和空气湿度，并注重遮阴。

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.

同时对不同浓度硫酸溶液控制生长箱内不同水平的湿度进行了测定和检验，亦效果良好，且对环境温度的适应性强，在5-35℃范围内同一硫酸浓度控制相同的稳定湿度。

Noting down amplitude voltage signals and phase voltage signals exported by interface circuit, with the weight value of pressboard the corresponding moisture value can be calculated, and a table reflecting the relation of voltage signals and moisture can be made.

记录经过调理电路处理输出的幅值信号和相位信号，根据绝缘纸板质量算出此时对应的湿度值，制成电压信号与湿度值对应的表格。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
