ptimization of relative rate constants for chlorination of xylene was carried out by golden section.

The rate constants of heatdecomposing reactions at 60°C and 80°C were 5.

In chemical textbooks, the rate constant educed from the rate equation V=k·C a A ·C b B .

The Mchaelis constant, K m and the effective electrochemical rate constant k′ ME have been determined.

To determine reaction rate constant in ethyl acetate saponification,according to the current textbook,keep the concentration of reactant ethyl acetate and NaOH equal,ignore the effects of the hydrolyzation of reaction product on G_t and G_∞,plot t against (G_0-G_t)/(G_t-G_∞) and determine the constant k by slope of the straight line.

Selectivity obstacle_avoidance research based on relative speed

By using auxiliary triangle method,analytic result for the relative speed on four quadrants of the sphere and the computer program were brought out,then 3D curved faces were plotted to illustrate the speed distribution.

Based on the experimental data processed by the MATLAB language, the relative speed distribution curve and vectorgraph are plotted.

A car-following model with stochastically considering the relative velocity in a traffic flow;

The essential view is that the relative velocity of the burning gas directs at the rocket after the burning gas has ejected, rather than the rocket before the burning gas has ejected.
