例如,您可以使用加法函数(在Scheme中称为+)来计算值。
For example, you can use the addition function (called + in Scheme) to calculate values.
基于进入系统的时间,写操作具有幂等性(不管操作多少次结果都不变的性质,比如取绝对值的函数就具有幂等性)和交换性(操作顺序不影响结果,比如加法就具有交换性)。
Write operations are idempotent and commutative, based on the time they enter the system.
建立了散射边界条件,并运用柱函数的加法定理,通过理论推导得到了聚焦区内刚性球形微粒的散射声压表达式。
After the scattering boundary conditions were set up, the scattering pressure expression of the solid sphere in the focusing area was derived by column function addition theorem.
If you're writing a one line function, whose sole purpose in life is addition, and, clearly, this is about addition, well, then it's, in fact, A reasonable to use a shorter symbol like A, but I do have to specify it's type.
如果你在写一个一行的函数,它唯一的目的是,做加法,显然这是关于加法的,好的,实际上,用一个短的标识符是合理的,像,但是我必须指明它的类型。
Oh, and actually before you skip your page in the notes, I realized I should write out for you what the addition is to start with. So, when we're combining two waves, 1sb what we have is 1 s a that we're adding together with 1 s for b, the second atom.
在你们翻过这页讲义之前,我觉得我应该写出加法,当我们把两个波函数放在一起时,我们用1sa加上,第二个原子。
