研究了面粉中蛋白质含量的示波滴定法。样品用H2 SO4 Na2 SO4 CuSO4 消化处理，N以NH4 +的形式存在于试液中，用过量四苯硼钠沉淀铵，沉淀过滤，过量的四苯硼钠用氯化四乙基铵标准溶液返滴定，以四苯硼钠切口消失为终点，计算出氮含量，再换算为蛋白质含量。与通用的标准分析方法相比较，本方法所用试剂无毒，终点变化敏锐，不需蒸馏吸收，不外加指示剂，具有操作简便、快速，测定结果准确可靠。

An equation is derived by theoretical analysis, to establish a relationship between suspended sediment concentrations and ADCP echo intensity output. For the survey at the entrance to Jiaozhou Bay, an ADCP is mounted on a moving vessel; the calibration coefficient in the equation is determined by in situ measurement. Then, a semi-empirical formula is obtained and used to calculate suspended sediment concentration profiles along several crosssections.

Phase-lagged cyclic boundary condition is implemented by a novel method in conjunction with the developed sliding interface technique to accurately simulate the arbitrary pitch ratio rotor/stator interaction without any modifications of the physics of the problem. It's for the first time to compose the computational area into one structured grids including both rotor/stator of centrifugal or axial turbomachinery with arbitrary pitch ratio. This method can eliminate the iteration of boundary conditions on the sliding interface and calculate the unsteady flow within rotor and stator simultaneously.

为了能够在较小的计算区域内不改变叶型而真实地反映出任意栅距比时的内部非定常流场，并避免近似仍采用相位后滞周期性条件，结合本文发展的网格技术，给出了一种新的实施方法，首次将动、静叶片数不等的离心式/轴流式叶轮机械转子、静子计算区域组合在一套结构化计算网格中，动/静叶排间的滑移界面完全按内场处理，避免了每一时层内，滑移界面处边界条件的迭代计算；并保证了每一时层，滑移界面处流动参数的守恒特性。
