按 渗碳形态特点,变形珠光组织可分为以下3种类型:(1)不规则弯曲片层型,即变形后的渗碳与轧制面呈大角度偏离且不规则弯曲的珠光。(2)带有剪切带的粗大片层型,即被渗碳剪切带分开且变形轻微的珠光。(3)精细片层型,即与轧制方向平行排列、片间距细小且渗碳严重变形的珠光。精细片层区域的比例随着轧制压下率的提高而增大。此外,重度冷轧变形还引起渗碳严重塑性变形和部分溶解。

结果表明在中期I阶段,这些杂种一代的近缘染色联会变化很大,每个花粉母细胞中二价形成的数目从平均2个到11.4个不等,甚至在某些花粉母细胞中,还发现极少的多价和非部分同源染色所形成的单基因组内二价;在后期I时,所有的二价分离,同时多数单价也分离,分离的二价和分离的单价都移向两极,从而形成两组染色;因为这时完整花粉母细胞中分离的二价在两组染色中总是对应出现,从而根据半二价上染色重组的位置可以分析在二价的四分时期发生在非姊妹染色之间的多种染色交换类型,如单交换、三线双交换、四线双交换、四线三交换和四线多交换。

In this thesis, the characteristics of software agents and their behavior modes are analyzed to find the influences of characteristics on behavior modes and to infer the master-slave and provider-requestor relationships among agents. Testing orders could be founded by relationships between agents. After the analysis of reciprocal effects among characteristics, we proposed that in the testing on a single agent, the autonomy should be tested first, the mobility is tested then, and the collaboration is tested finally. The testing of learning is incorporated into the testing of autonomy. A rolling-style testing method of software agents is proposed. Our testing method takes the IBM Aglets software agent language as an example, and develops testing tools under the IBM Aglets execution environment.

Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.
