The method How design standard rivet's CAD system in AUTOCAD 2000 is introduced in the paper,and develops the exterior DBMS's technology and interface ASI through ObjectARX application,especially expounds on the designing of communicate interface ASI between CAD system and DataBase。
Through researching material dosage , reactive tempera-lure and reactive time influence on the frational conversion of AEC and exterior,writers confirmed the optimum condition of the reaction: n (AEO) : n(NaOH) = n (ClCH2COOH) = 1 : 2. 5 : 1. 3;
It illuminates the forming motivation of the integration from the aspect of enterprise exterior; it also clarifies the integration mechanism of the integration from aspects such as the fusion, assembly, capital recombination between forest and paper industry and organizational network.
There are eight risk types of financial lease, which result from the characteristics of the trade and the exterior economic factors. The analysis concerned is based on the macro political, economic enviroment as well as law system.
Psychological and consciousness motion which is the basic of perception of motion dominate the exterior muscle motion, and without of it the motion of muscle will become spontaneous, losing stability and harmony.
This paper explains a new approach of A/D conversion,which means using PIC16C62× series to integrate interiorly two simulation comparators,while the monolithic integrated circuit sending out PWM profile unceasingly to the monolithic integrated circuit's own comparator entrance,the exterior simulation quantity also directed to the other two ends,keep on comparison,the both sides approaching to each other gradually to obtain A/D transforms precise value eventually.
