Due to difficulty of evaluation of micro grit protrusion topography after dressing of diamond grinding wheel, valid grit protrusion height, mean grit edge angle and grit protrusion homomorphy were proposed as characteristic parameters to evaluate iso-height behavior of grit protrusion, cutting behavior of grit edges and crystal integrity of diamond grit protrusion.

The condition for the existence of positive elliptic periodic solution was found using Floquet theory; and the theorem of the existence of positive elliptic periodic solution was proved by the method of upper and lower solutions and homotopy invariance theory of topology degree; then an example was given.

利用Floquet理论得到了该方程的正椭圆周期解存在的条件；然后利用上下解方法和拓扑度的同伦不变性理论，证明了该模型正椭圆周期解的存在性定理，并进行了实例验证。

So in this work, we focused no the following aspects: 1 The ecological effect of ephemeral resource on the rodent community; 2 The ecological isolation and coexistence mechanism for the sympatric species; 3 The effect of ecological process in a regional scale on the specie richness to investigate the community Patterns and limitation Mechanism of the desert rodents in this region, the main results and conclusions were as follows

为此，本工作立足于以下方面：（1）限制性资源对荒漠啮齿类动物群落的生态效应；（2）同域物种的生态分离与共存机制；（3）局域尺度的群落过程对区域物种丰富度的影响；对该地区的荒漠啮齿动物群落格局及其相关的制约机制进行了研究。主要研究结果和结论如下

Ice/ridge geometric parameters is established, and from computational analysis it is found that the unmonotonous variations of drag coefficient with ice concentration that frequently observed in sea ice field investigation mostly result from the influence of form drag from ice edge.

通过将原型条件下的冰-水总拖曳力考虑成表面摩拖曳力、冰侧形拖曳力和冰脊形拖曳力三部分，建立了冰-水总拖曳系数同海冰和冰脊几何形态参数之间的定量关系，并由计算分析发现现场观测到的拖曳系数随密集度的非单调变化就是冰侧形拖曳力分量作用的重要体现。

The result of simulation based on the method we have suggested on urea evaporation and pelleting shows the performance is satisfied.
