逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。

●设AND、OR和NOT分别表示按位与、按位或和按位求反运算，且X=10011011，Y=01111010，Z=11101000，则(NOT(X) AND Y)= (9) ， (Y OR NOT(Z))= (10) 。10011011011110101110100001100000(10)

封锚前锚具和预应力筋应如何处理？

根据《工程建设标准强制性条文》中的《预应力筋用锚具、夹具和连接器应用技术规程》（JGJ85-2010）锚具的静载锚固性能，应由预应力筋用锚具组装件静载试验测定的锚具效率系数和达到实测极限拉力时组装件中预应力筋的总应变确定。锚具效率系数不应小于（）。预应力筋总应变不应小于（）。
