The XRD result indicates that the axial ratio c/a of the tetragonal structure decreases with increasing the content of platinum, which leads to an increase of the deviation from unity of the tetragonal structure. So that, the anisotropy field of the ordered phase is improved and the coercivity is increased.

合金的X射线衍射结果表明：时效热处理后，随着Pt含量的增加，合金面心四方结构的有序相的c/a值逐渐减小，c/a值的减小增大了四方晶格结构的a与c方向的不对称性，使有序相的磁晶各向异性场增大，提高了合金的矫顽力

The possible reason is that in shock waves a nonstoichiometric ferromagnetic zinc ferrite is formed, in which the distributions of the cations in the A and B sites of the sublattice are different from that formed in calcination, it has stronger exchange interaction and leads to the increase of the magnetization.

可能的原因是冲击波合成了非化学计量比的铁磁性铁酸锌，改变了尖晶石次晶格中A，B位阳离子的分布而使其具有更强的交换相互作用而导致其磁化强度的增加。

It can be seen thatthe sublattice and total magnetization curves change from the P-type to Q-type behavior with increasing of value of crystal field.

随着晶场的绝对值的增加，子晶格和总的磁矩曲线由P-型转向Q-型。

Furthermore, the experimental k values were used to determine the associated activation energy, Ea, for the formation of La2/3TiO3-type phase using the Arrhenius plot and the following least-square equation, ln =-Ea/RT + A, where T is the annealing temperature, R is the universal gas constant, and A is a constant, resulting in Ea ~ 607 ?

第二部分则是以微观的方式来解析Pb2+离子与La4Ti9O24陶瓷以及La2/3TiO3-type相晶格之间的关系；利用化学共沉法来合成不同Pb2+离子添加量的La4Ti9O24陶瓷起始粉体，再以900 oC /1h的条件热处理；藉由选区电子绕射图谱以及X-ray绕射分析所生成之La2/3TiO3-type相结构；结果显示La2/3TiO3-type相之结晶结构为斜方晶之钙钛矿结构，符合空间群IbmmNo。

The degree of substitution between Cu(superscript 2+) and Zn(superscript 2+) is increased with increasing Cu(superscript 2+)/Zn(superscript 2+) entering crystal lattices of Zn5(CO3)26/Cu2(CO3)2, and the ratio of copper to zinc in Rosasite and Aurichalcite is unchangeable.

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。

PCL is not crystallizable when its content is lower than 50 wt% in theuncured novolac/PCL blends, whereas, after cured with 15 wt% HMTA, PCL is stillcrystallizable even the content of PCL is 30 wt%.
