但是在离结束游戏还有一分多钟的时候要求他计算一组分数的乘法时，他就没有耐心在这个问题上计算了。
But when it asked him to multiply a series of fractions with just over a minute left to play, he had no patience to work out the problem.
分析了交叉魏格纳分布函数中的拉冬变换是这些函数中分数傅里叶变换的可分乘法。
We have showed that the Radon transform of the cross Wigner distribution function is a separable multiplication of fractional Fourier transform of these functions.
在定义了正分数后可以定义有正分数参加的数的加法和乘法，并可以验证运算律。
After defined positive fraction Numbers, we might define addition and multiplication for positive fraction Numbers, and then we can also verify operation laws.
这里我们用到了乘法结合律也可以用消去律，本来这些运算律是对正整数乘法适用的，但对于有分数参加的乘法我们也规定适用。
Here we have used the associative law or the cancellation law for multiplication, which are satisfied for natural Numbers, now we assume they are satisfied with fraction Numbers.
