Application of microsoft VISIO to NET system forward engineering;

In forward engineering, rapid prototype holds an irreplaceable position and high efficiency.

Closely linked with engineering practices, this paper uses the widely-used 493 automotive diesel engine as the research object and analyzes comprehensively an important issue in the forward engineering development of automotive diesel engines—the mechanism, evaluation methods and optimization designing of cylinder bore deformation.

Research on integrated mechanism of forward logistics and reverse logistics based on supply chain

To reduce reverse logistics cost,improve customers convenience in product return and optimize channel selection decision of product return in reverse logistics,a multi-echelon reverse logistics network including initial collection point,central return center and return handling plant,was proposed based on quondam forward logistics network.

This paper describes the definition of reverse logistics, and analyzes the difference of reverse logistics and forward logistics in detail, then the function of reverse logistics is discussed.

Taking the silicon diode as an example,through an analysis of the diodes current-voltage characters and the avometer circuit,the writer finds out the reasons for the differences in the amount when measuring the positive direct current equivalent resistance with different ohm grades.
