The ingenuity of the financial community can be relied upon to establish financial linkages , where there is none officially allowed , through which what appears to be unmanageable financial risks can be managed and , consequently , financial contagion can be readily transmitted 金融界技高智巧，自能建立金融联系，使表面看似无法处理的金融风险亦能得到妥善管理，因此金融连锁效应亦会迅速扩散。

" we have to understand that as our influence in society increases , so does our responsibility . the commitment to duties and obligations is in itself an admirable life objective . young people who have embraced this objective will find their convictions strengthened through trials and tribulations , and will eventually achieve their goals . 以承担责任和义务为己任，本身就是远大的志向；年轻人怀著这志向，通过实践、磨练，坚定自己的信念，自能达到目标。
Very recently , schiller and muether at tubingen university suggested a new decomposition approach of the dbhf g matrix , and used to calculate the nucleon self - energy . they , sepa rate the g matrix into a bare nucleon - nucleon interaction v and correction term a g . the projection method is only applied to the correlation term a g , which is parameterized by four pseudo - mesons . then the nucleon self - energy in the dbhf can be calculated with the g matrix in the relativistic hartree - fock approximation 裸相互作用部分，即单玻色子交换势v对核子dirac自能结构的贡献可以通过相对论hartree - fock方法得到，只把关联部分用投影方法处理，并参数化为四种具有无穷大质量赝介子的交换，耦合常数与质量的比值是常数，从而关联部分g对核子自能的贡献也可以通过相对论hartree - fock方法求得。
The effective coupling constants including isoscalar and mesons and isovector and mesons in the rmf are extracted from the dbhf results in symmetric and asymmetric nuclear matter . two sets of effective interactions in the rmf approach are deduced by imposing a condition , where the dbhf scalar and . vector self - energy or scalar self - energy and binding energy per nucleon at each density and asymmetry parameter are reproduced , respectively 为了使我们提取的有效相互作用能够准确地再现出dbhf计算的核状态方程以及密度依赖的不对称能，我们采用第二种万法提取有效介子核子耦合常数，即要求在对称核物质中，每个密度处ilif计算出的标量自能及总结合能与dbhf给出的标量自能及总结合能一致，提取出。

However , the dirac structure of the nucleon self - energy in the dbhf can not be explicitly obtained in a numerical calculation . therefore a reliable decomposition of the dbhf g matrix is desirable , which is significant for the extraction of effective interactions , especially for the isospin dependence of the effective interactions 然而，在该理论方法中，如何合理地给出dbhf自能的dirac结构对于有效相互作用的提取，特别是同位旋矢量介子有效相互作用耦合常数的提取是十分重要的。
