在日暮时空里超脱——论王维诗中日暮意象的静韵

在王维诗的日暮意象中,传达的是一种通过生命本体的体验,在阴、阳之间,生、死之间超越时空悲剧、与自然万物同在的闲静自由的心灵状态。王维诗日暮意象的静韵是王维参禅、入画、回归大自然的超时间情感表达,有一缕青灯古佛旁的禅烟,让时间瞬间凝固永恒;几幅淡远的水墨山水,让时间在空间里停止,成为超时间的存在;些许大自然的生气,让生命融化在时空中,超脱而获得自由。     

浅谈托尼.莫里森小说里黑人自由的危险性

托尼·莫里森的小说主要关注的是非洲裔黑人在美国社会生态环境下的精神困境和人性的异化。在黑白文化的夹击下,黑人处于脱离两种文化的自由真空地带,他们不受约束的自由给他们的生活带来极大的危险,让他们的精神世界处于失衡状态。

卢梭自由观新探

卢梭的自由学说有着自己的独创。作为启蒙思想家,他主张消极的自由,即政治上的自由;而作为浪漫主义的人物,他又崇尚积极的自由。卢梭的自由学说涵盖了消极自由观与积极自由观,从而在一定程度上避免了单一重视某一自由观的缺陷,因而具有一定的合理性,但其思想的理想色彩和含混性也为后人的争辩埋下了伏笔。     

The nonleptonic two body B decays involving a light tensor meson in final states

The nonleptonic two body Bu,d,s,c decays involving a light tensor meson in final states are studied in the perturbative QCD approach based on kT factorization. The decay modes with a tensor meson emitted, are prohibited in naive factorization, since the emission diagram with a tensor meson produced from vacuum is vanished. While contributions from the so-called hard scattering emission diagrams and annihilation type diagrams are important and calculable in the perturbative QCD approach. The branching ratios of most decays are in the range of 10-4-10-8, which are bigger by 1 or 2 orders of magnitude than the predictions given by the naive factor- ization, but consistent with the predictions from the QCD factorization and the recent experimental measurements. We also give the predictions for the direct CP asymmetries, some of which are large enough for the future experiments to measure. We also find that, even with a small mixing angle, the mixing between f2 and f′2 can bring remarkable changes to both branching ratios and the direct CP asymmetries for some decays involving f2（′） mesons. For decays with a vector meson and a tensor meson in final states, we predict a large percentage of transverse polarization contributions due to the contributions of the orbital angular momentum of the tensor mesons.     

The loop effects on the chargino decays ～χ±1→～χ0 1ff ′in the MSSM

The lighter chargino three body decays ～χ±1→～χ0 1ff ′ via the W^± boson and the charged Higgs boson H^± were studied in the R-parity conserved Minimal Supersymmetric Standard Model （MSSM）. We treat ～χ±1 decays as production and decay of W^± and H^± i.e.,～χ±1→～χ01W^±（H^±） → χ0 1ff ′. Both higgsino- like and wino-like ～χ±1 decays were well investigated. These decays are calculated at 1-loop level and the loop corrections are found to be less than three percent. The signal of the charged Higgs H^± production from ～χ±1 decays is discussed. It will offer important information about the chargino and neutralino sector, as well as the charged Higgs sector in the MSSM.

美国控枪：利益纠缠的难题

如此轻松可以拥有枪,与《美国宪法第二修正案》有关,其内容是“纪律优良的民兵部队对自由州的安全是必要的,因此,人民持有并携带武器的权利不可受侵害。”     

关于两种活化熵△≠rS(θ)m(c(θ))和△≠rS(θ)m(P(θ))的讨论

用热力学方法处理过渡状态理论的艾林方程,选择两种不同参考点作为标准态,得出两个不同的计算公式,两种类型的活化自由能、活化焓、活化熵意义数值不同,对于理想气体的反应,两种类型的活化焓相等,活化熵不等,但两种活化熵之间存在定量关系式:△≠rSθm(Pθ)=△≠rSθm(cθ) (n-1)Rln[Pθ/RTcθ].     

《共产党宣言》中的自由思想解析

马克思本人经历了从革命民主主义到共产主义立场的转变，其自由观也实现了“消极自由”到“积极自由”的转变。《共产党宣言》中的“自由人联合体”集中表达了马克思、恩格斯关于“积极自由”的构想，同时其主体是“现实中的个人”，因而马克思主义“积极自由”观作为建立在历史唯物主义基础上的价值理想，由自由人联合体的物质基础、作为自由的实现方式的无产阶级工人运动以及自由时间为其提供可能性。
