Let us look at parallels between arithmetic using binary numbers and arithmetic using decimal numbers . 我们采用与十进制运算对比的办法来介绍二进制数的运算方法。
A slight acquaintance with numbers will show the immensity of the first power in comparison of the second . 稍微知道数的人都会知道,第一种力量比第二种力量大得多。
The concept used is that the bits of the two numbers to be added are made available to the adder synchronously . 所用的方法是,将相加两数的各位同步地输入到加法器中。
The variance is simply the average squared difference of all numbers from their mean or average value . 方差就是各个数的中值(或平均值)与各个数的差值的平方的平均值。
Therefore, the magnetomotive force in the air gap is essentially proportional to the primary ampereturns squared . 所以,气隙中的磁动势实际上与初级安匝数的平方成正比。
The classical greek art of writing and working with numbers did not continue where the babylonians left off . 古典希腊人记数和运用数的技术并未继承和发展巴比伦人的遗产。
Even allowing for the most generous expenses, there was no way he could have spent more than half of what was coming in . 即使把费用打得最宽,他也无法花掉大半数的收入。
Cumulative transfers on death have the same exemption limit but tax rates rise from 30 to 75 per cent . 死亡遗产累计数的免税额与馈赠相同,但起过部分的税率从30增到75。
We frequently need a formula which will give the number of watts of power when we know the current and the resistance . 我们常常需要一个已知电流和电阻时求功率瓦特数的分式。
The total rate at which recombination is occurring is certainly proportional to the number of electrons times the number of ions . 产生复合的总比率一定正比于电子数和离子数的乘积。
