Although only the problem of ambiguity of Patterson method is treated in this example , but the same approach can be applied to that of the isomorphous replacement method and the anomalous scattering method .

虽然本例只处理了含重原子晶体Patterson函数的双解问题，但所用手段同样适用于处理同晶型法和反常散射法的双解。

The isomorphous replacement of Si by B and Al in the MCM-41 inorganic framework makes some changes in the pore structure , therefore , B-Al-MCM-41 may have different properties in using for catalysis and adsorption .

Al、B同晶取代Si进入MCM-41无机骨架会使其中孔结构发生一些变化，因而合成的B-Al-MCM-41必将有不同的催化、吸附性能。
