Abstract: The present invention relates to carbon nanotubes and a preparation method thereof by using PET. The carbon nanotubes of the present invention are prepared by processes of alcoholysis of PET materials, processes of washing, crushing and calcining unreacted intermediates and so on. By the preparation method of the present invention, multi-walled carbon nanotubes prepared by using waste PET have a good conductivity, and are a structure of top-down array with low aspect ratio. The method of the present invention is not only easy to implement, but also does not need a catalyst, and turns the waste PET into treasure, which solves the problem of environmental pollution caused by the increasingly serious waste PET.

Abstract: A cloud water resource detecting system and method, the system includes computing device, and Raman lidar, microwave radiometer, millimeter wave cloud radar, wind profile radar and Doppler wind lidar in communication connection with the computing device. The Raman lidar and the microwave radiometer are configured to obtain temperature and humidity data of a cloud system. The millimeter wave cloud radar and the microwave radiometer are configured to obtain cloud water content profiles. The wind profile radar is configured to obtain a horizontal wind speed of the cloud system. The Doppler wind lidar is configured to obtain the vertical motion speed of a cloud bottom. The computing device is configured to calculate the total amount of cloud water according to the temperature and humidity data of the cloud system, the cloud water content profiles, the horizontal wind speed of the cloud system and the vertical motion speed of the cloud bottom.
