According to the characteristics and existent information of the geothermal fluid system in Kaifeng urban district the lateral runoff recharge method and the improved method of uniform arrangement of wells, this two kinds of methods are used to evaluate exploitable yield of geothermal water resource.

Evaluation of the interval point on uniform distribution;

Estimate of the interval midpoint on uniform distribution;

Evaluation of the interval centre on uniform distribution;

Image scrambling evaluation method of uniform distribution

The application and effect of the even distribution/Array pattern of diamond in diamond tools at home and abroad are introduced.

Then it specially introduces three methods: even distribution,normal distribution and exponential distribution, which are used to give bi.

In complete information system,by developing logical method and defining formulas and their semantics,the concept of even distribution for semantics of a formula is defined.

The paper studied and analyzed the interface wave of clad plate explosive welding used average arranging explosive, then put forward the new technology of unequal thickness arranging explosive.
