data constant

基本解释

Is the data constant?
数据是否为常量？
AdArray 0x2000 A flag value combined with another data type constant. Indicates an array of that other data type.
一个标记值，它是与其他的数据类型常数结合在一起使用的。它指明了包含其它数据类型的数组。
This paper is concerned with an initial-boundary problem of nonconvex scalar conservation laws with two pieces of constant initial data and constant boundary data.
本文研究具有两段常数的初始值和常数边界值的非凸单个守恒律的初边值问题。

So we're to assume we can get to any piece of data, any instruction in constant time, and the second assumption we're going to make is that the basic primitive steps take constant time, same amount of time to compute. Again, not completely true, but it's a good model, so arithmetic operations, comparisons, things of that sort, we're all going to assume are basically in that in that particular model.
因此如果我们假设在恒定的时间内,我们可以取得任何一块数据,任何一种数据结构的话,我们要做的第二个假设就是,基本的原始操作计算花费的时间是恒定的,这个假设也不是完全正确的，但这个模型其实挺不错的，因此算法操作，比较，这一类的事情，我们在这个特定的模型中都假设是基本的,操作，花费的时间是恒定相同的。
