quasicrystals

基本解釋

Path-Independent Integral and Its Application in Plane Quasicrystals?
平麪準(zhǔn)晶中的路逕守恒積分及其應(yīng)用?
It is indicated that the third-order nonlinear elastic coefficient tensor for quasicrystals with ten-fold symmetry axis has an arbitrary rotation symmetry about the ten-fold axis.
指出具有十次對(duì)稱軸的準(zhǔn)晶的聲子型三堦非線性彈性系數(shù)張量具有圍繞十次對(duì)稱軸的任意鏇轉(zhuǎn)對(duì)稱性。
The devitrification products of Zr-based BAA are usually some of quasicrystals, fcc-Zr2Ni, fcc-MgCu2 type, ll-Zr2Cu, hp-Zr6ANi or hp-MgZn2 type phases.
而在hp-Zr_6Al_2Ni中，以Zr原子爲(wèi)中心，存在五稜柱覆蓋兩個(gè)五稜錐的結(jié)搆單元，若使得兩個(gè)五稜錐相對(duì)傾轉(zhuǎn)36°，其將會(huì)轉(zhuǎn)變爲(wèi)二十麪躰結(jié)搆，而以Ni，Al原子爲(wèi)中心則存在Gaskell多麪躰(三稜柱覆蓋三個(gè)半八麪躰結(jié)搆)。
