The results show that a the variation of annual mean runoff of Huayuankou section exist an intrinsic dynamic mechanism, which is the results of joint action of affecting factor of periodicity and non-periodicity, having obvious chaos characteristic; b the correlation dimension of attractor of phase space is 5.09 and saturation inserted dimension is 14. It shows that to establish a mathematical model of the annual mean runoff system of Huayuankou at least requires 6 independent variables and the required saturation inserted dimension for rebuilding phase space is 14; c the steady estimate of Kolmogorov entropy is 0.14, showing the average predictable time of the annual mean runoff variation of Huayuankou is about 7 years and; d using nonlinear deterministic chaos model is more suitable to describe the variation of annual mean runoff of Huayuankou.

结果表明：①花园口年平均径流量变化存在着内在动力学机制，是由周期性和非周期性影响因子共同作用的结果，具有明显的混沌特性；②相空间吸引子的关联维为5.09，饱和嵌入维数为14，这说明要建立花园口年平均径流系统的数学模型，至少需要6个独立变量，重构相空间所需要的饱和嵌入维数为14；③Kolmogorov熵的稳定估计为0.14，说明花园口年平均径流量变化的平均可预报时间大约为7年；④用非线性确定性的混沌模型比完全的随机模型更适于描述黄河花园口年平均径流量的变化。

Unlike conventional approaches, this algorithm calculates the sum of variable-to-check messages only once at the initialization stage, and then updates it by simple recursions during the decoding stage.

与传统的串行译码算法不同的是，该算法只需在初始化时计算一次变量节点对校验节点软信息的求和式，而在译码过程中该式可通过简单地局部更新得到。

For example, the provisions of a zoning ordinance that limit the height or density of new construction can be reasonably likened to mathematical parameters that establish the limits of other variables.

Then the flow regime in the wells is studied.Firstly, the energy dissipation engineerings are systematically concluded. Then circular stilling well hydraulic model is made.The paper presents guidelines to aid the designers in determining optimum well geometry for their specific needs. General design criteria have been established to determine well size based on design discharge, Q, and diameter of the standard sleeve valve, D.

本文首先较系统地总结了消能工的研究现状；设计制作圆形深筒式消力井水工模型，通过试验及数据分析建立了圆形深筒式消力井各变量间的函数关系式，得出圆形深筒式消力井水力设计的基本方法，即已知设计流量和进水管直径，由曲线可得到圆形深筒式消力井的最优尺寸，并运用工程算例进行验证。

The optional order by clause can be used to reorder the tuple stream. The return clause constructs the result of the FLWOR expression. The return clause is evaluated once for every tuple in the tuple stream, after filtering by the where clause, using the variable bindings in the respective tuples.

可选子句order by可用来记录元组流。return子句构造FLWOR表达式的结果。return子句在where子句过滤后，使用在相应元组中绑定的变量为每一个元组流中的元组计算一次。
