A novel direction of arrival and polarization estimation of electromagnetic vector sensors mounted on the airframe is proposed based on biquaternion. The signal processing model for EM-sensor mounted on the airframe is made by biquaternion and then the eigenvalue decomposition of spectral matrix is obtained by means of the EVD of its quaternion adjoint matrix. The memory requirement for data is reduced, and more accurate estimation result is gotten by deducing the stronger orthogonality constraint between the sin- gal and noise subspaces on the field of biquaternion. The performance of the new algorithm is confirmed through numerical examples.

针对机载电磁矢量传感器阵列DOA和极化参数估计问题，提出了一种基于复四元数估计方法，该算法利用四元数建立机载电磁矢量传感器阵列信号处理模型，然后利用四元数联合矩阵的特征分解得到阵列数据相关矩阵的特征分解，一方面使得计算过程中数据的贮存量大大减少，另一方面通过推导得到信号子空间和噪声子空间在四元数域上的正交性从而使DOA和极化参数佑计的精度更高，仿真证实了本算法的有效性。

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

From the first chapter to the forth chapter, it summarizes four France capitalistic ideas on equality: the idealistic equality, the empirical equality, the systematized equality, and the singular equality. Then, it can be explored minutely from representative character, advance presupposition, doctrinal content, objective state, practical counterpoint, institutional embodiment, the tend of practice, theory extending and so on. In the fifth chapter, it researches into their contradiction and contestation between the four equalities, indicates their class-conscious essence, and tries to find out a direction to sole these questions. In the sixth chapter, as the intrinsic tendency of soling these deep-seated contradictions of the four equalities, the paper traces the process of France communism from chimerical idea to scientific theory, so that it can point out a gospel: the scientific socialism is the one and only way to surmount these embarrassments of capitalistic theories on equality. At the last chapter, according to our reviews about theories of equality during the hundred years in France, it can conclude some political apocalypse from our history. Owning the wisdom, we could choose our road to the equality, by using these experiences in the west political histories.

第一章到第四章，总结了带有法国资本主义特征的四种平等思想：法国理想平等观、法国经验平等观、法国体系平等观和法国单元平等观，并在代表人物、前提预设、学说内容、目标状态、现实对应、制度体现及其实践倾向和理论扩展等方面进行细致化地考察；第五章，探析四种平等观之间的内在矛盾和论争，指出其学说的阶级本质，同时试图探寻解决问题的方向；第六章，作为解决以上四种平等观之间深层矛盾的内在趋向，文章考察了法国共产主义平等思想由空想向科学的发展，进而指出只有科学社会主义才能走出资本主义平等理论的泥沼；在文章的最后，本文依据对法国百年平等思想史的考察，总结出历史所带给我们的政治启示，以使我们用西方政治的历史经验来选择我们自己的平等之路！
