8-2同余式 8.2.1有理整数环中的同余的定义 定义8.5设m是一个正整数,若a,b∈Z,且ba∈(m),亦即m(b-a),则 称b与a模m同余,记作b=a(modm)。不难得到,b与a模m同余就是它们用m做带 余除法所得的余数相同。整数模m同余为一等价关系,验证如下:

There are many concepts that are used in fuzzy logic that sometimes become useful when studying fuzzy control. The following problems introduce some of the more popular fuzzy logic oncepts that were not treated earlier in the chapter or were treated only briefly (a)The complement(\not )of a fuzzy set with a membership function has a membership function given by A(x)=1-u(x). Sketch the complement of the fuzzy set shown in Figure 2.6 on page 30 (b)There are other ways to def ine the\triangular norm\for representing

3.1.2 A general uniqueness theorem The key issue for uniqueness of solutions turns out to be the maximal slope of a=a(a) to guarantee uniqueness on time interval T=[to, t,, it is sufficient to require existence of a constant M such that

Blessed are the young, for they shall inherit the national debt Herbert hoover When a government spends more than it collects in taxes, it borrows from the private sector to finance the budget deficit. The accumulation of past borrowin is the government debt. Debate about the appropriate amount of government debt in the United States is as old as the country itself. Alexander Hamilton be- lieved thata national debt, if it is not excessive, will be to us a national blessing, whereas James Madison argued that \a public debt is a public curse \Indeed, the location of the nations capital was chosen as part of a deal in which the federal
