This paper introduces how to use PLC realize PID automation control system in constant liquid level system of waterworks though a instance project. It adjusts liquid level by control the valve though PID arithmetic and deals with outside program, makes the liquid level constant at the expectation value. The adjusting time is the same as manual control, but the water quality is better. Its advantages are reaction rapidness, auto-control disengage intervenor, quick protection of fault, more safety and stabilization.

本文以一工程实例介绍了如何用PLC在水厂的滤池实现PID恒水位控制，它通过PID算法和外围的程序处理，通过控制阀门开度来调节水位，使水位基本恒定在期望值，并且阀门调节次数基本与手动调节一样，但水质却明显好很多，更重要的是对现场适应能力强，反应快，而且完全脱离人为干预进行全自动控制，对故障也有快速保护，更具安全稳定性。

First, UWPBL model(The University of Washington Planetary Boundary Layer Model) is used to retrieve typhoon's sea level pressure from sea surface winds data of SeaWinds which aboard on QuikSCAT and these strength results are analyzed. Then the variational method is applied to decompose the sea surface winds field into two parts: the vortex and irrotational environmental flow field, the UWPBL model is used again to retrieve ShanShan and YaGi typhoons' sea level pressure from the vortex flow field, the results of typhoon's central positions are analyzed by comparing the results with the results of direct retrieving, NCEP's data and typhoon annual reports. It turns out that the accuracy of the typhoon's sea level pressure central position has been obviously improved, This method offers a new idea for the study of typhoon from microwave scatterometer data.

本文首先利用QuikSCAT散射计获取的海面风场资料，利用华盛顿大学行星边界层模式对台风海平面气压场进行反演，并对其强度进行了分析；然后对获取的海面风场，采用变分方法对风场进行分解，分解出无旋和有旋风场，对分解出的有旋风场，再利用UWPBL模式对珊珊和魔羯台风的海平面气压场进行了反演，对所得结果与通常直接反演、NCEP海平面气压场及台风报文资料进行一一对比，结果表明：新的反演定位的方法对台风海平面气压场中心气压的定位精度有了大幅度的提高，此种定位的方法为散射计资料在台风中的实际应用开辟了一条新的思路。

In the single factoranalyzes, It shows a negative related line to Nitrogen dosage andoil-content. The relation of Phosphate dosage and oil-content is curverelated. To some extent, the using of Phosphate will raise the oil-contentof rape, but it will be lower if Phosphate is too much. The Kainite dosageand oil-content is curve related. The relation of Sulphur dosage andoil-content is related to the experiment place. The oil-content is higherwhen the Nitrogen dosage at low level, the Phosphate dosage at middle level,the Kainite dosage at middle level in this condition.

单因素效应分析氮肥施用量与含油量呈直线负相关；磷肥施用量与含油量呈曲线负相关，在一定范围内，施用磷肥有利于油菜含油量的提高，过量则降低含油量；钾肥施用量与含油量呈曲线负相关；硫肥施用量与含油量相关性随试验地变化不同。

The problem was that the water pump could not pump in a nine-story residential building, as result the water would soon be used up. I arrived at night; found that liquid level relay broke down. then I installed a three-pole knife switch next to liquid level relay to power the pump manually, so the problem with no water to be solved provisionally. then I fitted the Level relay for them, finally the water pump can pump automatically again

有一次来电，物管说他们小区没有电工，说一幢9层的住宅楼一楼的水泵泵不上水，水池很快就会无水用了，晚上我到达现场，原来是液位继电器坏了，我当时已带上了三极的闸刀开关，在继电器的旁边装上闸刀开关，手动供电给水泵，临时解决了没水用的问题，过后才为他装上液位继电器，又恢复了自动泵水。

OD estimation was divided into fixed steps, with every step containing a bi-level programming. The upper-level problem was a generalized least squares estimator, while the lower level problem was a stochastic user equilibrium model. Namely, based on generalized least squares estimator and stochastic user equilibrium, a new estimator of the OD matrix was proposed by target matrix and traffic counts updating.

将OD估计分为固定的步数，每一步都是一个双层规划，上层为广义最小二乘估计，下层为随机用户均衡分配模型，即以广义最小二乘估计和随机用户均衡分配模型为基础，通过更新估计模型中目标矩阵和实测路段上的流量来估计OD矩阵。
