By means of the nuclear parton distribution studied only with lepton deep-inelastic scattering experimentaldata,the J/φ“normal nuclear absorption”and energy loss effects are studied in a Glauber formalism at HERA andRHIC energies.Assuming that the absorption cross section σ_(abs)increases with the charmonium-nucleon center of massenergy,the results reveal a significant dependence of the σ_(abs)on rapidity y at RHIC energies.The initial-state energyloss effect,which is found important only at HERA energies,is also considered,and its influence should be eliminatedwhen we studied the absorption effect at low collision energies.Finally,we also present the theoretical prediction forLHC.
By means of the nuclear parton distribution studied only with lepton deep-inelastic scattering experimental data, the J / φ “normal nuclear absorption” and energy loss effects are studied in a Glauber formalism at HERA and RHH energies. Assuming that the absorption cross section σ_ (abs) increases with the charmonium-nucleon center of massenergy, the results reveal a significant dependence of the σ_ (abs) on rapidity y at RHIC energies. The initial-state energyloss effect, which is found important only at HERA energies, is also considered, and its influence should be eliminatedwhen we studied the absorption effect at low collision energies .Finally, we also present the theoretical prediction forLHC.

摘 要：早期阅读是幼儿的需要，并且对幼儿各方面发展乃至终身的学习具有重要意义。从时代背景来看，知识经济时代对早期阅读的需要已成为当今早期教育的重要课题。从教育背景来看，幼教都愈来愈重视早期阅读。因此，研究早期阅读具有重要意义。首先分析了早期阅读兴趣培养的重要性，接着对理解和尊重幼儿的阅读特点进行了阐述，最后对培养幼儿早期阅读兴趣的方法进行了论述。 关键词：幼儿；早期阅读；兴趣 一、正确阅读的重
