As a liquid , the blue phase shows the 3d - space group symmetry , just like crystals , which arouses people ' s interest 作为一种流体，液晶蓝相能像晶体一样有三维空间群对称性，这引起了人们的广泛兴趣。
2.
In addition , the nanometer - size particles of bn was doped into the mg - si - based thermoelectric materials as the second - phase for the first time . the result showed that the introduction of nano bn could decrease the thermal conductivity of the mg2si - based thermoelectric material and as a result its power factor were improved 论文还首次在mg一si基热电材料中引入bn纳米粒子第二相，结果表明:在mg一si基热电材料体系中引入bn纳米粒子第二相能有效降低材料的热导率，提高热电材料的优值系数。
