实验结果表明，该方案应用于土壤信息采集系统，不仅可以达到比粒子群优化(Particle swarm optimization，简称PSO)算法和量子粒子群优化(Quantum-behaved particle swarm optimization，简称QPSO)算法更好的寻优结果，而且具有比遗传算法更理想的位置拟合精度，是一种有效可行的传感器配置方法。

A two-layer framework with particle swarms cooperative optimization and a mutation parameter is introduced by the QPSCO algorithm for larger searching scale and quicker convergence. Moreover I the residual sum of squares in least-square principle is introduced into the fitness function to enhance the fitting precision of the sensor position curve.

在QPSCO算法中，采用双层的多粒子群协同优化结构，同时引入参数变异策略，在扩大搜索范围的同时加快该算法收敛；将加权最小二乘法的误差平方和引入适应度函数中，以提高传感器位置曲线的拟合精度，从而实现传感器的优化配置。

The sum of BCOD of BODst test and XH measured through batch respirometer is consistent with the BCOD of BODlt test and the ratio between them was in the range of 0.88-1.02 with average 0.94. The BODlt test is time-consuming and the microorganisms'population and their metabolic characteristic are different from that of the actual activated sludge process. So the respirometry has the advantage of time-validity and representation for the actual activated sludge system.

6呼吸测量法测得的BCOD明显小于长期BOD测试方法的结果，这是由于后者得到的BCOD包括所有的活性微生物COD组分；短期BOD测试得到的BCOD与异养菌COD之和与长期BOD测试得到的BCOD比较接近，两者之比在0.88-1.02之间，平均值为0.94；长期BOD测试耗时长，测试用的微生物种群及其代谢类型都与实际活性污泥过程明显不同，因此，从测试结果的时效性和代表性方法考虑，短期BOD测试更具优势。

In vector algebra, addition are defined to add coordinates entries respectively,and this system of operation is the direct sum Z Z={|a,b are integers} of integers ring Z,the operations are+=,=.

向量代数加法就是这样按照分量加法在运算，再加上按照分量的乘法，这个运算体系就是整数环Z的直和Z Z={|a，b为整数}，其上的运算就是+=，=。

In Chapter 3, we discuss the synchronization of coupled dynamical systems on condition that the external coupling matrices are n × n irreducible symmetric real matrices with zero row sum and nonnegative off-diagonal elements and internal coupling matrices are m × m asymmetric matrices.

在第三章我们讨论了耦合动力系统中，当外部耦合矩阵是n×n阶实对称不可约，行和为零且对角线以外的元素非负的矩阵，内部耦合矩阵是m×m阶非对称矩阵时耦合系统的同步问题。

As for the explorations on the rhythm of Rubato, the writer concludes seven kinds of factors contributing to the rhythm of Rubato, and based on this, writer goes further to make combination , classification and sum-up to these factors, in hope of setting certain tone for the vocal works and further explaining the repeated musical part or intensifying some kind of expressive effect. All these aim at serving to the musical structure and expressive force, at displaying the individual's singing style better,and at bringing out the charm of the performing art

对于自由节奏Rubato的探索，本文主要归纳出造成自由节奏的七种因素，并在此基础上对其进行合并分类、总结，以期奠定声乐作品的某种基调，并进一步阐释被重复的音乐段落，或者加强某种表情效果，进而为乐曲的结构与表现力服务，更好的展现个人演唱风格，展示出表演艺术的创作魅力。
