The infinite series diverges, meaning that its sequence of partial sums does not tend towards any finite limit.Equivalently, one says that lacks a sum. 此無(wú)窮級數發(fā)散，即其部分和的序列不會(huì )趨近于任一有窮極限，可等價(jià)地認為不存在和。
Up to a certain sum of the interior angles on one side of the transversal the two lines might indeed meet. 截線(xiàn)一側兩內角到達一定的和數，兩直線(xiàn)可能一定相交。
The greater the sum, the greater the cross-correlation coefficient obtained in this way will be. 和數越大，以這種形式得到的相關(guān)系數也越大。
