第一题 已知传递函数为G(s),输入r(t)= Asinwt使用部分分式法和复数法,证明稳态输出为:

第一题 10(s+2)s+4.10 2)(s+4 1.G(s) S+10(s+5)(S+10) 所以Kn=25

Rhythm in English speech is based on stress. rhythm unit节奏单位)is formed by stressed syllable, together with unstressed syllables which may come before the stress and after it.The unstressed syllables before the stress are said very quickly, so they are very short, as short as you can make them; but the stressed syllable is as long as before, so there is great difference of length between the unstressed syllables and the stressed one, e.g

Ag与g在体外结合时,由于Ag的物理 性状及参与条件的不同,而表现出形式 多样的反应结果。利用Ag与Ig在体外结 合的特异性,可用Ag或Ig的已知一方, 检测未知的另一方,从而对传染病作出 诊断或病原微生物的分型鉴定等

1.证明性质(4),性质(6). 2.证明有界闭区域上的连续函数必可积 3.设是可度量的平面图形或空间立体,∫,g在Ω上连续,证明
