For probing the isospin dependence of the medium correction of two-body cross sections, the results show that the behavior of the excitation function of stopping for medium size nuclear collisions can provide clearer information than that for heavier systems.

我们的结果还表明测量中等大小质量的系统在中能重离子碰撞中的核阻止本领激发函数比测量重的系统能提供更为确切的有关两体截面介质修正的信息。

We consider that the better system of measuring for the size of granular mixtures may be the number of elements. So we designed another kind of large system experiment, the experiment of Tokamak plasma system with the characteristic of jillion element. Under the condition of Ohmic heating and Low confinement mode, the interaction among elements will increase with the debasement of plasma confinement, causing SOC.It validates the assumption that SOC mostly depends on the mechanism of interaction among elements in a large system, in other way.

为通过精密可控实验手段探讨大尺度散粒体组元之间相互作用强度对SOC的影响，利用磁约束受控核聚变托卡马克装置实验数据，在欧姆加热或L模放电的条件下，对HL-1M边缘区等离子体粒子输运的统计性质分析发现，反常输运具有SOC的特征。

For the purpose of constructing mammary gland specific expressional vector, we use the updream regulation sequence of bovine BLG to regulate lacS gene to express in mammary gland. Positive clone cells are selected and purified by the expression Neo gene and report gene EGFP. So the cells can be used as sources to create transgenic animals by nuclear transfer techniques.
