A series of MOF-based hierarchical porous material, namely IPD-mesoMOF-1\u02dc9, based on nanoscale MOFs of MIL-100, MIL-53, HKUST-1, DUT-5, DUT-4, MIL-101, MIL-101NDC, MIL-101BPDC and MIL-110 respectively, forming the permanent interparticle porosities by using close packing, and preparation methods thereof. A common synchronization signal can be generated having a frequency versus time pattern that is the same as the frequency versus time pattern of the supply network during normal operating conditions. The distortion compensation amplification device includes a correction value calculating unit which calculates the correction value based on the transmission signal supplied from the modulation unit. At least one shield layer is adjacent to an outermost first layer of the first layers wherein the shield layer has a first projection and the first layers have a second projection wherein the first projection and the second projection are different.
