在影响无线网络同步的因素中，网络拓扑结构逐渐引起人们的关注。通过研究RGG模型中网络聚类系数和网络次大特征值之间的关系，来探索聚类系数对网络收敛性能的影响程度，并希望从有边界效应和无边界效应两种情况入手对其进行研究。通过仿真实验发现在无边界情况下的聚类系数是一个常数，与其他因素无关，有边界情况下其值与环境参数相关。从理论上推导了无边界聚类系数的理论值，并给出了有边界情况下的推导思路。
在影響無線網絡同步的因素中，網絡拓撲結構逐漸引起人們的關註。通過研究RGG模型中網絡聚類繫數和網絡次大特徵值之間的關繫，來探索聚類繫數對網絡收斂性能的影響程度，併希望從有邊界效應和無邊界效應兩種情況入手對其進行研究。通過倣真實驗髮現在無邊界情況下的聚類繫數是一箇常數，與其他因素無關，有邊界情況下其值與環境參數相關。從理論上推導瞭無邊界聚類繫數的理論值，併給齣瞭有邊界情況下的推導思路。

In the factors that affect wireless network synchronization,the network topology structure gradually draws atten-tion of researchers. By studying the relationship between network clustering coefficient and the secondary largest eigenvalue in RGG model,the effect of network clustering coefficient on network convergence performance was explored under two conditions with and without boundary effect. Through the simulation,it is found that the clustering coefficient under the borderless condi-tion is a constant,which is not related to other factors,and the clustering coefficient with boundary effect is related to the envi-ronment parameter. The theoretical value of clustering coefficient without boundary effect is derived theoretically. The thought of derivation with boundary effect is offered.
