By using the group-chain, the wavefunctions of the 4f〓 configuration for RE ions are also expressed as linear combinations of group-chain basis functions in Butler's irreducible representation notation. The matrix elements of the CF Hamiltonian then are calculated by means of the Wigner-Eckart theorem and factorization lemma of the jm factors. Before the CF level fitting, a point-charge calculation of the conventional CF parameters B〓 has been performed by means of the lattice-sum technique from the known crystal structure data. The corresponding parameters in the group-chain are calculated by the conversion relationship between two schemes that proved identical in essence, which are usually used as initial values in the fit to the experimental levels. The ratios of the same k-value CF parameters are suggested as the constraint conditions in the fit, in order to utilize fully the symmetry distortion degree of the studied system.

利用群链理论，属稀土离子4f〓组态的波函数表示为以不可约表示标记的群链基波函数的线性组合；借助Wigner-Eckart定理和2jm和3jm因子的分解定律计算了晶场哈密顿的矩阵元；根据点电荷模型和已知晶体结构数据，利用点阵求和技术计算得到传统晶场参数B〓初值，相应的非传统形式的群链参数初值则由两种方案下的转换关系求得；这些初值通常作为非线性拟合晶场能级计算的初值，系统的对称性畸变信息则反映在以同阶晶场参数的比值作为能级拟合的约束条件。

Part Two discriminates the Ex-Soviet Marxist Philosophy and Western Marxists' Marxist Philosophy, intent on expounding the fact that the Ex-Soviet Marxist Philosophy simply sticks to, dogmatize and even mechanize the Marxist Philosophy. In parallel this section makes a systematic exposition of Western Marxist Philosophy from three aspects, i.e. the philosophical meta-problem, philosophical methodology and ideology.

第二部分通过对前苏联马克思主义哲学观和西方马克思主义的马克思主义哲学观的辨析，旨在阐明前苏联的马克思主义哲学观是对马克思哲学观的僵化、教条化、机械化的理解；并从哲学元问题、哲学方法论两个方面阐述了西方马克思主义的马克思主义哲学观。

In the summer of 1998, over two frantic weeks in July, I wrote an essay titled The Future of Online Learning .(Downes, 1998) At the time, I was working as a distance education and new media design specialist at Assiniboine Community College, and I wrote the essay to defend the work I was doing at the time.

在西元一九九八年夏天，七月的两个疯狂的星期里，我写下了一篇文章《在线学习的未来》（唐棣芬，1998）当时，我从事远程教育工作，是一名阿西尼博因社区大学的新媒体设计专家，我写这篇文章是为了捍卫我当时的工作。

"In fact 2002 the bottom enters Chinese market service of Ou Wei spy," Xu Kai wave says, We are managing the client database of more than 80 million in China, organize the sale activity that carries out more than 2000 times every year, managing more than 600 million yuan finance affairs to trade, own the call center of on 1000 banquet, and pervade the sth resembling a net of content drift net of countrywide B2C and B2B and powerful data center.
