To test a bit field to determine whether a specific enumeration value is present, use the Boolean logical operators.
若要测试位元栏位，判断特定列举值是否存在，请使用布林逻辑运算子。
Unless this is so, the Boolean logical operators will not be able to extract the individual enumeration values that are stored in the field.
除非情况如此，否则布林逻辑运算子就无法抽取栏位中所储存的个别列举值。
Insofar as a human brain that knows about logical conjunction (Boolean AND) would similarly classify logically conjoined sentences, this TLU knows something like logical conjunction.
就像懂得逻辑连接(布尔运算AND)的人脑可以类似地将逻辑连接的句子分类那样，TLU也懂得一点逻辑连接之类的东西。
