整数解

The discussion is based on some property of arithmetic function.

为了判断整数是否为亲和数，在讨论数论函数性质的基础上，找到一种验证一个整数是否是亲和数的方法，从而给出了f=x2x+1不与任何正整数构成亲和数的结论，这里x为偶数，即关于y的方程σf(x=σ=f+y不存在正整数解。

After the joint probability density function between the 'float' ambiguity solution and the fixed ambiguity solution is introduced in this section, the conditional probability density function of the integer ambiguity solution is gotten according to this joint probability density function.

在介绍了模糊度浮点解和其固定解的联合概率密度函数之后，本文根据这个联合概率密度函数得到了模糊度整数解的条件概率密度函数。

The main work of this paper is: First,we get the condition that the equation 2py~2 = 2x~3 + 3x~2 + x have no positive solution by the method of simple congruence and decomposition.

利用简单同余法、分解因子法等初等方法，给出了方程2py~2=2x~3+3x~2+x无正整数解的条件。

And all of these approaches are derived from the full rank decomposition technique for the incidence matrix.

LAST INTEGER SOLUTION IS THE BEST FOUND!

以上整数解是最优解

It is very interesting that the conditional expectation of the integer ambiguity solution is just equal to the admissible integer estimator of this ambiguity vector.

非常有趣的是模糊度整数解的条件期望就是这个模糊度向量的可容许整数估值。

For the expectation and variance of both the integer ambiguity solution and the baseline fixed-solution, their calculation formulas are introduced in this section.

对于模糊度整数解的期望和方差以及基线位置参数固定解的期望和方差，本文也介绍了其计算方法和相应的计算公式。
