A prolapse is a downward or forward displacement of one of the pelvic organs from its normal location. *A variety of terms are used to describe female genital prolapse. *A cystocele is a downward displacement of the bladder. *A cystourethrocele is a cystocele that imcludes the urethra as part of the prolapsing organ complex

In the chapter we shall develop a method for representing a sinusoidal forcing function or a sinusoidal response by a complex number called a phasor transform,or simply a phasor. By working with phasors we shall effect a truly remarkable simplification in the steady state sinusoidal analysis of general circuits

In the chapter we shall introduce the study of circuits characterized by a single energy-storage element--a capacitor or a inductor. It will be shown that the equations describing such a circuit may be put in a form involving an unknown variable and its first derivative. Such an equation is referred to as a first-order differential equation, thus we shall refer to circuits which contain only a single energy-storage element as first-order circuits

定理1设向量a≠0,那么,向量b平行于a的充分必要 条件是:存在唯一的实数,使b=a 证明充分性是显然的,只需证必要性. 设bla.取,当b与a同向时取正值, 当b与a反向时取负值,即b=a.这是因为此时b与a同向

定理1(无穷小与函数极限的关系) 在自变量的同一变化过程x→x(或x→∞)中,函数f(x) 具有极限A的充分必要条件是(x)=A+a,其中a是无穷小 简要证明令a=f(x)-A,则fx)-a
