The design of temperature collection software and the configuration of hardware are described in details. The software developed in LabVIEW program language can acquire temperature data rapidly  what's more  the acquired data can be displayed real timely and saved to the disk. It is proved that the system is easy to practical use and can extraction mean square value and mean value after gathering the stable high-speed temperature. The function can be extended according to the demands of users. 2012 IEEE.   An exploratory analysis of spectral indices to estimate vegetation water content using sensitivity function EI期刊论文  OAI收割 2012 Wu Jianjun; Zhang Jie; Lu Aifeng; Zhou Lei 收藏  |  浏览/下载：26/0  |  提交时间：2012/11/23 Water content  Deforestation  Fuels  Function evaluation  Mean square error  Moisture control  Moisture determination  Optical properties  Optical waveguides  Vegetation
