HUANG Jiqing gave a brilliant exposition with E. Argand's mobilism thought as to the dynamical evolution process of the tectonics in On Major Tectonic Forms of China.

在《中国主要地质构造单位》中，他运用阿尔冈活动论的思想，阐述了中国大地构造的动力演化过程。

A simple relationship of dielectric relaxation is proposed,which can completelyexpress the high and low frequency dielectric relaxation in PMN-PT relaxorferroelectrics.It fits complicated experimental Argand diagram closely.

通过对弛豫铁电体PMN-PT频域介电谱的分析，提出能完全描述高、低频不同弛豫特性的复杂弛豫的简单关系式，并且完好地拟合了不规则的弛豫Argand图。

The possible reason is that doped Zr〓 ion enters the interstitial sites for its small ionic radius and no dipole complexes were formed. Monovalent ion F〓 has been reported to improve the scintillating performance greatly. Our results show that Agrand diagrams of F〓: PWO crystals obey an modified Cole-Cole equation. The crystals present similar dielectric relaxation phenomena to but have much higher activation energy than that of RE〓: PWO crystals, which originate from the 〓 dipole complexes. The co-doping of trivalent Y〓 and pentavalent ion Nb〓 does not always show a better scintillation performance than that of solely doped samples, which could be attributed to the existence of the 〓 dipole complexes, which counteract the solely doping effect.

而Zr〓由于离子半径太小，可能进入间隙位置，不形成类似的偶极缺陷；一价负离子F〓的掺入提高了晶体闪烁性能，阻抗谱测试结果表明F〓：PWO晶体Argand图符合修正的Cole—Cole方程，晶体同样表现出介电弛豫现象，并具有比RE〓：PWO晶体中高得多的弛豫激活能，可能起源于形成的〓偶极缺陷；Y〓和Nb〓双掺的PWO晶体并没有显示出两种离子单掺优点的叠加，阻抗谱测量结果表明，在双掺晶体中可能形成〓偶极缺陷，使两者掺杂作用相互抵消。
