Based on the uncertainty of flood risk, a quantitative economic losses evaluation index is proposed from the angle of passive damage losses and both active prevention and reduction, Comments on further improving the flood risk evaluation system are presented.

On lack of passiveness in English verbal small clause;

Bayes prediction modeling for dynamic loss of manufacturing accuracy;

Study on the model of dynamic loss of manufacturing accuracy;

By using nonlinear finite element analysis code ANSYS/DYNA to build a dynamic analysis model of the round-link,the paper analyzes the kinetic energy loss of the round-link chain under the different initial conditions and the energy absorption under chain blocked,according to the dynamic process of the round-link chain under chain blocked condition.

Analysis of flow loss induced by inlet total pressure distortion in a small fan;

In this paper,the designing method of the fasting cooling system of furnace is introduced in detail by demonstrating how to calculate flow loss,select turbine and design transfer.

The results show that the flow loss is reduced with the increasing of the coolant mass when the injection angle is 30°at the instant of injection from single row of holes.
