In coal mines fire consists of one of the main disasters, which usually take place for the reason that the water content of coal is over low. Over low water content of the coal transported with belt more likely brings about flying coal dust, which, when accumulated to some degree, will triggers explosion. Given that in China now coal is mainly transported with belt in coal mines, the author in this paper proposes a way to measure water content of coal transported with belt by use of microwave attenuation method and improve the measure accuracy through RBF neural network algorithm. This method is proved to be scientifically reasonable through laboratory simulation and experimentation. The theoretical basis and technical support are provided to increase the accuracy measuring water content of coal transported with belt by this method.

Analyses of ultrathin cryosections are generally performed after freeze-drying because the presence of water renders the specimens highly susceptible to radiation damage. The water content of a subcellular compartment is an important quantity that must be known, for example, to convert the dry weight concentrations of ions to the physiologically more relevant molar concentrations. Water content can be determined indirectly from dark-field mass measurements provided that there is no differential shrinkage between compartments and that there exists a suitable internal standard. The potential advantage of a more direct method for measuring water has led us to explore the use of electron energy loss spectroscopy (EELS) for characterizing biological specimens in their frozen hydrated state.We have obtained preliminary EELS measurements from pure amorphous ice and from cryosectioned frozen protein solutions. The specimens were cryotransfered into a VG-HB501 field-emission STEM equipped with a 666 Gatan parallel-detection spectrometer and analyzed at approximately −160 C.
