In the first place, the foundation of the electrostatics basic theory, development and appliance of modern electrostatic engineering are introduced in the paper. And it points out that electrohydrodynamics(EHD) is a signified offshoot and investigated hotspot of modern electrostatic engineering. The EHD's brief introduction is studied.In the second place, some experiments of transport character of water molecule on electric field in bio-materials, which are the thawing experiments on high voltage electric field, the electroosmotic dewatering experiments and the concentration experiments of liquid materials on high voltage field, the drying experiments of crop seeds on high voltage electric field, the drying experiments of Chinese traditional medicine (Huajuhong) on high voltage electric field, are performed. The results show that the water molecule velocity in materials is accelerated, the reminded efficient ingredients is enhanced on electric field. The experimental results are of significance.At last, the experimental mechanism are done from vary point of view. It is thought that the electric force tows polarity water molecules in bio-materials, the ions carried energy enter into bio-materials and acts with the water molecules, and gradually transfers kinetic energy to water molecules. The process changes the water groups into single water molecule, and enhances dewatering and thawing. As far as EHD is concerned, the dewatering and thawing of materials are accelerated because of 'electromotion pump' as a result of electroosmosis, electric field and force in dielectric liquid. The mathematical model of crop seeds by high electric drying is set up. Duringthe dewatering and thawing, the efficient ingredients are more kept down because it has not a heat transfer process in the energy and mass transfer of the electric field process and the temperature of materials does not rise.High electric drying, high electric thawing and electroosmosis dewatering technology are novel technology, and will initiate new domain in electrostatic application. The mechanism is studied from the electrohydrodynamics(EHD).
