To solve the problem of "reliablity", calculation scope and the high thresholds in the operation of the graphics automatic calculation quantity system in the practical use, "read schemata" graphics calculation quantity technology is analyzed. This technology has the features of direct visualization, clear presentation, no requirement for memory in work, revisability, meeting cost engineer’s work habits, low threshold in operation, wide application scope, easy proofreading and so on. The axis module algorithms and information structure are given. The experimental results show that this method is effective, feasible and superior to other graphics quantity calculation system. Finally, further research problems are presented, such as the structure of knowledge base, calculation rule set and so on.

To solve the problem of "reliablity", calculation scope and the high thresholds in the operation of the 3D graphics automatic calculation quantity system in the practical use, "read schemata" graphics manual calculation quantity technology is analyzed. This technology has the features of direct visualization, clear presentation, no requirement for memory in work, revisability, meeting cost engineers work habits, low threshold in operation, wide application scope, easy proofreading and so on. The main function of graphics manual counting system is described with "reading schema". The functions of the drawing display and the manual calculation area are given. The experimental results show that the method is effective, feasible and superior to other 3D graphics quantity calculation system and can be applied in the quantity calculation of various professional engineering.

Direct electron microscopic study of biological molecules has been hampered by such factors as radiation damage, lack of contrast and vacuum drying. In certain cases, however, the difficulties may be overcome by using redundent structural information from repeating units and by various specimen preservation methods. With bilayers of phospholipids in which both the solid and fluid phases co-exist, the ordering of the hydrocarbon chains may be utilized to form diffraction contrast images. Domains of different molecular packings may be recgnizable by placing properly chosen filters in the diffraction plane. These domains would correspond to those observed by freeze fracture, if certain distinctive undulating patterns are associated with certain molecular packing, as suggested by X-ray diffraction studies. By using an environmental stage, we were able to directly observe these domains in bilayers of mixed phospholipids at various temperatures at which their phases change from misible to inmissible states.
