Analysis on gas potential of Fuyu and Yangdachengzi Reservoir in Daqing Placanticline through time matching relation between source rock and cap rock;

Traditional image matching algorithm has the advantage of high matching precision,but large computation increase the matching time.

This paper researches the relationship among the selected points,recognition rates and matching time to estimate the selected points in different fingers according to different required recognition rates.

Research on impact time of impact crusher based on simulation;

In order to research the shape of the crusher hammer before and after the damage as well as the impact time of the granular rock,the article indicates the simulation of the impact process between the crusher hammer and the granular rock with the transient dynamic software,MSC.

The relations of erosive ratio to impact time, impact angle,and impact velocity are revealed,the formula of erosive relation is also quantitatively deduced.

The influences of time lag dynamic derivatives on the evaluation of the spin time history of a modified airplane;

Simulation of Osteoporotic Process of Cancellous Bone with Time History;

According to the actual working condition of JJ300/43-A shape derrick, the impact load is applied on the top node of derrick twice and the other impacts are all zero by using the time history analysis method.
