交叉点

According to the above study results, especially the steady operation of two-sludge system（2A/O+N 2SBR）, it can be proved that denitrification and excess phosphorus uptake are relatively independent and intersectant biological processes. The overlap is that denitrifying phosphorus removing bacteriawhich possesses the two bacterial metabolisms, could utilize nitrate as an electron acceptor for phosphorus uptake. The two-sludge system can not only combined biological phosphorus removal and denitrification processes to form a process in practical wastwater treatment , but also solved the main difficulties of current single-sludge systems:①the sludge age competition between phosphorus removing bacteria and nitrifier;② the substrate competition between denitrification and dephosphatation.

以上的研究结果，尤其是时间序列的双泥生物反硝化除磷脱氮系统工艺（2A/O+N 2SBR法）的稳定运行，不仅证明了生物脱氮与生物除磷是两个既相对独立又相互交叉的生理过程，其交叉点是同时拥有硝酸盐还原性和超量吸磷这两种生化特性的细菌进行的反硝化吸磷脱氮生化反应，而且双泥系统工艺克服了常规单泥生物脱氮除磷工艺的两大问题（①聚磷菌和硝化菌的SRT相互干扰；②反硝化与生物除磷竞争VFA），同时保证了脱氮和除磷效果，排水指标达到污水综合排水标准（GB8978-1996）的一级标准，具有实际工程使用价值。

There is a lot of overlap in these categories.

在五种不同类型中有很多的交叉点。

With simultaneous picosecond temporal resolution and nanometer spatial resolution for each framing image, is proposed in this dissertation.

分幅电子显微技术是将电子显微技术的高空间分辨特性与交叉点扫描多光阑分幅技术的高时间分辨特性相结合，能够以ps量级的时间分辨率和nm量级的空间分辨率获得样品在不同时刻的多幅显微图像。

In the Uzawa algorithm, we use the HX preconditioner for the primal variable. The numerical results indicate that the new algorithm has good parallelization scalability and the iteration counts are independent of the mesh size and the jump range as for the floating subdo mains and interior cross-points.

数值实验结果表明，不论是对光滑系数还是对有无浮动子区域及有无内交叉点的跳系数情形，我们所设计的并行算法HX-Uzawa-p的迭代次数都基本不依赖于网格规模及系数跳幅，且具有很好的并行可扩展性。

To each of these domains there corresponds a generator , and to each cross-over there corresponds a relator

这些区域中的每一个对应于一个生成元，而每个交叉点对应于一个关系子。

Because, while you may find yourself caught in the crossfire of an embattled economy, no one can evict you from your experiences or repossess your memories.

因为，虽然你也许发现自己身处麻烦经济的活力交叉点上，但谁也不能拿走你的体验，不能没收你的记忆。

The improvement is 45% for the phase-lag of S2 after assimilating the altimetric data of the crossover points, while the correction for the diurnal constituents is not so good as for semidiurnal constituents.

利用基于最优插值法的混合法将交叉点的调和常数同化到动力模式中，同化后S_2分潮的迟角精度改进最大，可以改进45％，结果显示高度计资料的分析结果对模式结果的精度影响很大。

Waste for slate shingles varies from 8 to 20 percent,depending on the shape,number of irregul

板岩木瓦的废物根据不规则性的形状、交叉点的数字和数字屋顶的变化从8%到20%。

The process of adding shadows used here is simple: for each object intersection point, which I call hitpoint, we trace a ray toward the light, and if this ray hits another object so we have shadow at hitpoint, and them we reduce the rgb color at the hitpoint by a percentage.

在这里使用添加阴影过程很简单：为每个对象的交叉点，我称之为hitpoint，我们跟踪一对光线，如果这种射线击中另外一个对象，以便我们在hitpoint阴影，和他们，我们减少RGB颜色在hitpoint一个百分点。

A move consists in playing a stone of one's color on an empty intersection, or in passing.

一着棋，可以是将己方的一枚棋子放到空白的交叉点(包括棋盘的边和角上的点)上，也可以不下，即弃着。
