The math models of the tree structure chart and the net structure chart are formed by describing the different road state abstractly.The tree structure chart model is presented without consideration of U structure and ring structure. This kind of model has a notable feature: there is a line only between the two dot in the chart, which means that there is only one road from one point to another point in expressway ,so the tree structure chart is called "single roads chart".

在不考虑U型路段和环路的情况下，提出了高速公路的树状结构图模型，该模型具有一个显著的特点：图中两点之间有且仅有一条连线，这意味着由高速公路上的一个地点到达另一个地点仅有一条通路，也称这种高速公路树状结构图为"单路径图"；考虑到包含U型路段和环路的高速公路路况，提出了高速公路的网状结构图模型，这种模型可抽象成一个连通图，即图中任意两点之间至少有一条直线相连，这意味着由高速公路上的一个地点到达另一个地点有多条通路，也称这种高速公路网状结构图为"多路径图"。

The inheritance of poly-eggs was investigated by crossing and reciprocally crossing APIV with monoembryonic rice variety IR36,Minghui No.77 and Longtepu B,respectively.It was suggested that the production of poly-eggs is probably controlled by gametophytic genotypes,rather than sporophytic ones.

通过多胚水稻品系APⅣ与单胚水稻品种IR36、明恢77和龙特浦B正反杂交，研究APⅣ的多卵遗传行为，表明APⅣ的多卵性状可能不是由孢子体基因型决定的，而是由雄配子体基因型决定，属配子体遗传的范畴。

Stamens (6-)12-100+, inserted at or near base of floral tube, exserted, dimorphic in most species, 6 solitary in front of sepals with thick filaments and large anthers, 12-100+ in clusters in front of petals with thin filaments and small anthers, rarely monomorphic, then all filaments thin, subequal.

In a same cloud band, the variation of temperature is small meanwhile the temperature is lower.The convective bubbles were observed in the warm clouds under the middle of the cumulostratus on 21,June 1992. The bubbles clearly show that they are one kind of mesoscale organization. It suggests that the synoptic system is situable to produce convective bubbles. Its contrastly analysed that the particle concentration and the liquid water content are higher.the particle spectra is similar,the particles captured by 2D-C probe are bigger in the bubbles.
