With the increase of La/Al mole ratio, the La modified alumina’s acid sites increase at the beginning, reach maximum value with 0.01 of La/Al mole ratio, and then decrease rapidly and lower than normal alumina.
La改性球形氧化铝样品酸中心的数量则先随La／Al摩尔比增加而增大，并在La／Al摩尔比为0.01时达到最大值，当La／Al摩尔比继续增大时，酸中心的数量迅速减小并低于纯氧化铝。
