用给定的水位数据，选取73个分潮，利用潮汐调和分析，计算分潮的调和常数，利用调和常数结果选取4个主要分潮和2个浅水分潮，对实测水位进行回报，计算余水位，平均潮差，高低潮的潮时潮高并精确到min和cm，最后计算该站的潮汐类型。(By using the given water level data, 73 tides are selected, and the harmonic constants of the tide are calculated by the harmonic analysis of the tides. 4 main tides and 2 shallow water tides are selected by the result of the harmonic constant. The measured water level is returned, the residual water level, the average tidal range, the high tide tide and the high tide height are calculated to min and cm. Finally, the calculation is made. The tidal type of the station.)

DVHop
针对基于双曲线定位的DV-Hop算法中误差项的异方差性引起的定位误差大的问题，提出了一种基于加权双曲线定位的DV-Hop改进算法。算法分析了基于双曲线定位的DV-Hop算法模型中误差项的异方差性，用加权最小二乘法对异方差性进行纠正，对加权最小二乘法中的权值矩阵进行了推导并得到与跳数相关的最佳权值矩阵，使得误差项满足同方差性，所得估计值更加接近最佳线性无偏估计。仿真实验结果表明，所提算法在节点定位精度上较现有的基于双曲线定位的DV-Hop算法都有一定提高。(Aiming at the problem that the heteroscedasticity of observation errors leads to low locating accuracy in DV-Hop algorithm based on hyperbolic positioning, this paper proposes an improved DV-Hop algorithm which based on weighted hyperbolic positioning. The algorithm analysis the heteroscedasticity of the error term in the model and takes advantage of weighted least square method which corrects heteroscedasticity straightforwardly. Then, the weight matrix related to least hops between nodes is deduced, the estimators thus obtained are more close to the best linear unbiased estimator. The simulation results show that the location performance of the improved algorithm is better than that of the exsiting DV-Hop algorithm which based on hyperbolic positioning.)
