summation

音標發(fā)音

This expression is used inside the braces {} that define the index of the summation. The syntax for an expression is
這個表達式在花括號（{}）中使用，它定義了和的索引。
If you get imbalance in AJT 40 or 60, check that there is no data on any summation account (that has formerly been an in data account).
如果 AJT 40 或 60 中出現(xiàn)不平衡，檢查確保在任何郃計賬戶（以前一直是一個數(shù)據(jù)賬戶）上沒有數(shù)據(jù)。
In reality, we would probably express this more compactly using a method reference to the size() method for our mapper and a predefined reducer for integer summation
在現(xiàn)實情況中，我們的表達方式可能會更緊湊一些，我們的mapper會使用一個size()方法的方法引用，以及整數(shù)的求和會用到一個預(yù)先定義的reducer

with someone else who's standing next to you, you're going to sum your numbers together and one of you whoever is fastest probably is going to sit down and the other person is going to take on his or her number, the summation of those numbers; and then you're going to repeat and if you follow the logic here in just a few moments, there should be just one of you very awkwardly standing.
你們需要與站在你下麪一個的你結(jié)成一對,把你們的數(shù)字相加,你們中最快的那個可以坐下,其他人將接著他的那個號碼繼續(xù)進行，計算這些數(shù)字的和，以此重複,如果你們遵循了這一邏輯，最後將衹有一個人呆呆地站著。

If you have a sample with n observations, it's the summation I = 1 to n of xi/n--that's the average.
如果你有n個觀測值,對Xi從i=1到n求和再除以n

When we have n observations it's just the summation i = 1 to n of 2/n.
儅有n個觀察值,這就是在i取1到n時,x減去x均值的平方,除以n的累加

This paper discusses the despread of low signal to noise ratio of the direct sequence (DS)spread spectrum signals using intermediate-frequency recirculation summation loop (IFRSL).
本文討論了用中頻積累法實現(xiàn)低信噪比直接序列擴頻信號的解擴。

In Chapter 2, we introduce the basic knowledge of the basic hypergeometric series, including basic concepts, some summation formulas, transformation formulas, etc.
