一、图板、丁字尺、三角板 图板用作画图时的垫板，要求表面平坦光洁；又因它的左边用作导边，所以左边必须平 直。 丁字尺是画水平线的长尺。丁字尺由尺头和尺身组成，画图时，应使尺头靠着图板左侧 的导边。画水平线必须自左向右画，如图 1—1 所示。 图 1—1 图板和丁字尺

10.1 Basic definitions A failure is an unacceptable behaviour exhibited by a system —The frequency of failures measures the reliability —An important design objective is to achieve a very low failure rate and hence high reliability. —A failure can result from a violation of an explicit or implicit requirement

An understanding of the nature of wastewater is essential in the design and operation of collection, treatment, and reuse facilities, and in the engineering management of environmental quality. To promote this understanding, the information in this chapter is presented in eight sections dealing with (1) an introduction to the constituents found in wastewater

Determining wastewater flowrates and constituent mass loadings is a fundamental step in initiating the conceptual process design of wastewater treatment facilities. Reliable data for existing and projected flowrates affect the hydraulic characteristics, sizing, and operational considerations of the treatment system components
