STUDY OF THE EXPERIMENTAL INSTRUMENTS IN THE TOTALLY ENCLOSED AND GROUPED FORMS
Dong Chunye Gao Qinglian
Reforms are made on the covered or the half-closed expreimental instruments and experimental methods for handling the easily igniting and expoding, poisonous and harmful materials in the current chemistry textbooks. After the publication of Study of the whole Closed and Separated Forms, hydrogen is taken as an example to sum up a series of experiences inpusing the whole closed experimental instruments and the operation methods. Byadopting the effective absorbing and transformable methods for handling the poisonous and harmful.materials, surely the experimentalists may be kept healthy, and the envionments unpolluted.At the same time the internal laws are also expressed in the present chemistry experiments.
【Key Words】：
