Then for each row from the fact table scan, the foreign key is also hashed and probed into the bit vector to determine whether the current fact table row is filtered out.
然后针对事实表扫描的每一行，外键也被散列并探测到位向量中，从而判断当前的事实表行是否被过滤掉了。
One thing that can be confusing about R's "everything is a vector" approach is that row-wise and column-wise operations may not adhere to your intuition.
关于R的 “所有东西都是向量”方式，容易引起混乱的一点是行操作和列操作可能不符合直觉。
But if you wanted to create a vector to sum each row, you might be inclined to try the following.
但是，如果希望创建一个向量来求每行的总和，您可能会编写下面这样的代码。
Two new flame feature vectors are defined: one is the flame detection context based dynamic feature row and the other is the optimal flame feature area vector.
算法定义了两种新的火焰特征向量：火检上下文动态特征切入列，火焰特征最优区域。
But it is very difficult to compute the number of non-negative matrix with fixed score row or column vectors, so to compute the number of tournament matrix with fixed score vector is also difficult.
竞赛矩阵和竞赛图由于具有固定行和向量及列和向量的非负矩阵类的计数，是组合数学的一个非常困难的问题，因此对具有固定得分向量的竞赛矩阵的计数问题也比较困难。
