Get a small tool called a hygrometer to check humidity levels and keep them as low as you can-no higher than 50%.

可利用称为温度计小工具检查湿度水平，并把它维持在尽可能低的水平——不超过50%。

The results show that the sensor has high sensitivity, small hysteresis. The capacitance and impedance of the sensor vary with the relative humidity and the frequencies.

结果表明：元件的灵敏度较高、湿滞较小，元件的电容值和阻抗值随频率与相对湿度而变化。

The results indicate: lower latitude, smaller horizontal scale, lower humidity and some vegetation with small stoma resistance are good to develop oasis.

结果表明，能使绿洲扩大的主要条件是低纬度、小尺度，并具有低水汽、较高温度的环境以及较小气孔阻力的植被。

Last year Dr Smith and Alanson Sample, a researcher at the University of Washington in Seattle, powered a small humidity and temperature sensor using nothing more than the energy gleaned from a television station 4.1km (2.5 miles) away.

Where they see magic, the locals see 90-degree heat, humidity and mosquitoes the size of small birds.
