Methods The antianaphylaxis activities of myricetin was measured by passive cutaneous anaphylaxis, dextran-induced itch and DNCB-induced delayed type hypersensitivity in mice,respectively.

采用小鼠同种、异种被动皮肤过敏反应、右旋糖酐致小鼠全身瘙痒反应和2，4-二硝基氯苯所致小鼠耳廓皮肤迟发型超敏反应实验，探讨杨梅素的抗过敏作用。

The formation of Fe—O—Fe antiphase boundaries are suppressed by the doping Al due to the improvement of the cation ordering, and the high field magnetoresistance that roots in spin-dependent scattering at the antiphase boundaries is reduced.

阳离子有序度的提高使来源于自旋相关电子在反相边界处散射的高场磁电阻明显降低，导致了样品的磁电阻在x=0.15时达到了最大值。

It is shown that the structure-induced Fano resonance and SOC-induced Fano resonance exist in the charge conductance in con- sequence of the bound states interference with the conductance ones. At the same time, the Fano resonance and antiresonance structures are also found in the spin polarization.

利用晶格格林函数方法，发现由于stubs和SOC产生的势阱使系统中出现束缚态，这些束缚态与传播态之间相互干涉导致电导中出现Fano共振结构，同时在对应的自旋极化率中也出现Fano共振或反共振结构。
