We stayed at the Stratosphere because I like the rides and it was cheap. Plus I like the Blackjack there, but have since discovered the rules at the Tropicana are a little more favorable.

    请教一个文献中一句话的理解问题。有这么几句话“the mass outflow increased by a facotr of 6 between two observations separated by 18 months”和“Other stars showed changes in MLR by a facotr of 1.5 or less.”请问这其中的“a facotr of X”该怎么理解?是不是表示新结果是在原有结果前面乘以x而得到?
