Potential Species' Distribution System, a new GIS-based system, has been designed and implemented to predict the potential distribution of species by using presence data only. The result, normally overpredicted by traditional Environment Envelope Model, is improved by using hierarchical cluster arithmetic that can reduce the influence caused by outliers.

Influence of tolerance factor on the complex engine performance was analyzed, then a new tolerance analysis and optimization method for complex product was proposed. The method synthesized effects such as tolerance size, tolerance location and component error accumulation on the product performance. Tolerance was then optimized based on the result of tolerance analysis and processing cost of different parts.

Secondly, for the same hash function, the sample with the minimum hash value is selected as the global sample and the local samples are combined at the center node to filter out the biased effect of duplicated updates.

然后，对于相同散列函数产生的样本选取具有最小散列值的样本作为全局样本，完成局部样本集在中心节点的合并，滤除在分布节点上的重复更新对样本偏斜的影响。

The result show that particle numbers of diameter of floccule which are of narrow-dispersed size between 7 500～20 000 nm are more than 82% of the total when the pH is between 8.5 and 10,with concentation of Fe~(3+) around 40 mg/L and areration rate in the range of 0.10 L/min and 0.14 L/min.

The results indicate that multiple reflections are favorable to the increase of depth. When the focal position is above the surface, the absorptive intensity on the front decreases, so the cutting depth decreases. When the focal position is below the surface, the position on the front with the maximum power intensity is downward. The intensity distribution is toward the deeper position, the cutting depth increases. But if the negative focal distance is extremely big, the intensity of the deeper position attenuates sharply with the increase of focal radius and light distances, so the depth deceases.

正离焦切割时，前沿吸收的总激光功率密度减小，切割深度减小；负离焦切割时，最大激光功率密度值的位置下移，使得前沿功率密度分布朝着深部推进，切割深度增加，若负离焦量过大，表面光斑直径和光程增加，更深位置的功率密度减小，切割深度减小；随着激光功率增加、切割速度减小，则前沿弯曲程度减小，被激光直接照射的前沿部位增长，前沿吸收激光功率密度增加，切割深度增加。

But we don't care about Battlegrounds.
