This study investigated the effect of sludge retention time on the removal of high concentrations of organic carbon, nitrogen and phosphate in a bench-scale sequencing batch reactor operating with a three-stage alternating anoxic-oxic sequence and step-feed to treat synthetic wastewater.

本研究利用阶梯进流配合缺氧／厌氧－好氧三阶段交替操作之批式反应器系统（ the step-feed alternating anoxic/anaerobic-oxic sequencing batch reactor， SAOSBR ），处理含高浓度碳、氮、磷之合成废水，并探讨污泥停留时间，对系统硝化、脱硝、除磷特性及处理效能的影响。

Accordingly, this paper proposes a short-term traffic flow prediction model of data fusion algorithm based on Filtering step by step. Compared with traditional prediction model through Kalman Filtering Theory, this model is not only reduce the computation and lower model to center processor's request, but also ensure estimate accuracy.

基于此，本文提出了一种基于分步式滤波的数据融合算法(Fusion Algorithm of Filtering Step By Step ，简记FAFSS)的短时交通流量预测模型，该模型与传统的基于卡尔曼滤波理论的预测模型相比，不仅减少了计算量，降低了模型对中心处理器的要求，而且保证了预测的精确度。

First of all,the procedure and methods of the implementation of the STEP neutral file are introduced,and the EXPRESS representation for the geometric and non geometric entities of a 2D engineering drawing are also discussed.

首先简要介绍了STEP中性文件实施的过程和方法，以及二维工程图IGES和STEP实体的对应关系，然后介绍了二维工程图基本几何实体和文本注释、尺寸标注等非几何信息的EXPRESS描述，及其映射生成STEP中性文件的方法，并给出一个实际工程图的STEP中性文件（由自行研制的AP201应用工具的后处理器生成），最后对STEP中性文件的优缺点进行了评价。

Firstly, the operating principles of the STEP-NC program generator were introduced.

为实现STEP-NC程序的自动生成，开发了STEP-NC程序生成器。

To step in is to become involved. For example,"The coach wanted to let the team work out their own problems on the court, but after getting beat badly in the first quarter, he decided to step in," or "I let them argue, but had to step in when they started punching each other."

step in」就是介入、干预的意思，例如：「教练本来想让球队在球场上自行发挥，但他们第一节被对手痛宰后，教练就决定出手指导」，或是「他们争论的时候我没有插手，但他们开始互殴时我就不能坐视不管了」。

The system is designed according to the mechanism of CAD Standard Part Graphies Files. SQL Server 2000 is selected as the host and construct the database of part liabrary due to characteristic parameter. STEP, viz. ISO 10303, is issued by international standardization organization, and here ,this paper gives the definition of product information model oriented part41 and part44 in STEP and six basic definienses which describe the product information to ensure the information in the product information model correct and shareable . This paper also presents method of creating and extracting product information on engineering draught and product data exchange and integration between CAD system and database manager system.

论文中采用&CAD标准件图形文件机制&，用SQL Server2000数据库建立了零件的特征参数数据库，完成了零件库的特性参数库建库工作；依据国际标准化组织的STEP标准即ISO 10303中的Part41，Part44两部分内容以及STEP标准中描述产品信息的六个基本的类库定义，提出了一种产品信息模型，保证了产品信息模型中信息的正确性和共享性，实现了工程图样中产品管理信息的建立和提取以及数据库系统与图形文件中的管理信息交换与集成。

The three key technologies of code translation that includes design of class library, reading method of parameters in toolpath planning and STEP-NC coordinate system is disserted on.

详细论述了STEP-NC译码中的3项关键技术：类库设计、刀轨规划参数读取方法以及STEP-NC坐标系。
