The influences of decay coefficient of the cavity and the intensity of the field on the phase distribution as well as its fluctuation are discussed.The results show:if there is absence of the phase damping,the phase distribution oscillates with the period π/λ.It presents single leaf at t=nπ/λ,but it splits into multi-leaf construction during the evolution period due to the interaction between the field and the atoms.

结果表明：当腔不存在损耗时，光场相位分布概率以π/λ作周期性振荡；且在t=nπ/λ时刻，光场和原子是退纠缠的，相位分布概率曲线在极坐标图中呈单叶型结构；但在演化周期内，由于光场与原子的相互作用相位分布概率曲线会劈裂为多叶型结构。

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

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"。
