1本章学习目的 通过本章的学习,要重点掌握沉降和过滤这两种机械分离 操作的原理、过程计算、典型设备的结构与特性,能够根 据生产工艺要求,合理选择设备类型和尺寸。 2本章应掌握的内容 a沉降分离(包括重力沉降和离心沉降)的原理、过程计 算、旋风分离器的选型

一.(16分)选择题(每题只许选一个答案) (1)孔板流量计的孔流系数C当R增大时,其值 A总在增大B先减小,后保持为定值总在减小D不定 (2)某液体在内径为do的水平管路中稳定流动,其平均流速为,当它以相同的体积流量通 过等长的内径为d2(d2=do2)的管子时,若流体为层流,则压降p为原来的倍

Korovkin定理 如所知,逼近的目的,是用简单的函数来逼近复杂的函数本章讲述用多项 式序列逼近有界闭区间上连续函数的可行性 §1. Weierstrass第一定理 在实变函数的数学分析中,最重要的函数类实连续函数类Cab与连续的 周期函数类C2n Ca,b]是定义在某一闭区间[a,b]上的一切连续函数所成的集合;

An explorer is trying to reach the Holy Grail, which she believes is located in a desert shrine d days walk from the nearest oasis. In the desert heat, the explorer must drink continuously. She can carry at most 1 gallon of water, which is enough for 1 day. However, she is free to create water caches out in the desert. For example, if the shrine were 2/3 of day's walk into the desert, then she could recover

Notes for Recitation 14 Counting Rules Rule 1(Generalized Product Rule). Let be a set of length-k sequences. If there are: n1 possible first entries, n2 possible second entries for each first entry, n3 possible third entries for each combination of first and second entries, etc. then:

Problem 1. The following two parts are not related. Try them, to make sure you un- derstand the jargon of random variables distributions, probability density functions, etc. Ask your TA if you don't understand/remember what some phrase means. (a)Suppose X1, X2, and X3 are three mutually independent random variables, each having the uniform distribution
