折叠萝卜螺生物学初步研究

对采自南昌近郊池塘折叠萝卜螺一种群的生物学进行了初步研究，并就其贝壳的形态和其它种群作了比较，测量了210个折叠萝卜螺的壳高（H），壳宽（W）和体重（T），三者之间的关系可分别表示为：T＝0．0009H^2.632,T=0.0047W^1.8915,W=0.6899H-0.3437,在野外，折叠萝上课累在南昌地区从2－6月都能产卵，其中3－4月达高峰期，在室内3，5，6月为产卵高峰，4月几乎不产卵，折叠萝卜卵的孵化率很高，平均孵化率为95．66％，最高达100％，最低也有89．5％，幼螺的死亡率高达50％以上。     

微波消解ICP-AES法同时测定花岗石中铜、镉、铬和砷

Hydrogenation Properties of Zr Films Under Various Conditions of Hydrogen Plasma

The hydrogenation properties of Zr samples with and without an Ni overlayer under various plasma conditions were investigated by means of non-Rutherford backscattering and elastic recoil detection analysis.The theoretical maximum hydrogen capacity,66.7 at%,could be achieved at a hydrogen absolute pressure of-2Pa and a substrate temperature of-393K for a plasma irradiation of only 10min;this was significantly greater than that for gas hydrogenation under the same hydrogen pressure and substrate temperature.It was also found that the C and O contamination on the sample surface strongly influences the hydrogenation,and that the maximum equilibrium hydrogen content drops dramatically with the increasing total contamination.In addition,the influence of the Ni overlayer on the plasma hydrogenation is discussed.

Covariant Perturbation Theory of Non—Abelian Kinetic Theory

A “double perturbation” theory is presented in the framework of the kinetic theory of quark-gluon plasma.A solvable set of equations from the double perturbation are derived and proven to be gauge invariant.The Landau damping rate for the plasmon at zero momentum is shown to be a convergent series in correlators.     

κ玻色子q相干态的反聚束效应

研究了q变形湮没算符高次幂（αq^k,κ≥3)本征态的反聚束效应，并就κ=3的情况用数值计算方法研究了q变形参数对该效应的影响。结果表明，当q变形相干态中谐振子的强度x=|z|^2在某些区间内取值时，αq^k的本征态将呈现反聚束效应，并且这一效应明显地受到q参数的影响。当参数q取定时，随着q变形光场强度的变大，该光场的光子数涨落在经典（或量子）和量子（或经典）特性之间交替地变化。

Spectrum Simulation of Li-Like Aluminium Plasma

X-ray emission spectra for L-shell of Li-like aluminium ions are simulated by using the flexible atomic code based on the collisional radiative model. Atomic processes including radiative recombination, dielectronic recombination, collisional ionization and resonance excitation from the neighbouring ion （Al^9＋ and Al^11＋ ） charge states of the target ion （Al^10＋） are considered in the model. In addition, the contributions of different atomic processes to the x-ray spectrum are analysed. The results show that dielectronic recombination, radiative recombination, collisional ionization and resonance excitation, other than direct collisional excitation, are very important processes.
