To experimentally study the charmoniumψ′cascade radiative decay,ψ′→γ′χcJ→γ′γJ/ψ, a generator which describes correctly all angular distributions is a necessity.

The differential cross section of e +e -→ωπ 0 and the decay rate of ω→π +π -π 0 are derived, and a simulation program is coded for the generator of e +e -→ωπ 0 taking account of initial state radiative correction with G.

Syntactic priming(SP)in sentence production refers to the tendency of speakers and writers to reuse syntactic structures that they have recently processed.

From the perspective of structural transfer,the paper studies the process of Chinese sentence production by foreign students and confirms the corresponding relation between the two languages is an important factor in their sentence production.

It is important to measure meson productions in heavy ion collisions in order to understand the dynamics of heavy ion reactions and the properties of nuclear matter.
