The results are as follows:(1) With the imposing of orthopedic force of simulating maxillary protraction on maxilla, in the sagittal direction, the maxillary complex of the SD Rats in experimental group grows more quickly than that in two control groups, and the extent of the maxillary complex increases more evidently. The maxillary complex displays anti-clockwise forward and upward rotation.(2) With the imposing of orthopedic force on maxilla, upper incisors exhibit labial-inclined, labioclination of lower incisors changes insignificantly, and the shape and the dimension of skull are not affected significantly.(3) The expression of TGF-3 , in frontomaxillary sutures and palatomaxillary sutures shows different intensity in different extent of time. But The expression of TGF-{3, in experimental group is more intensive than that in two control groups, and that in operated control group and natural growth group has no significant difference.

There are two main factors govern the diverse structures of complexes 15 and 16:(1) reaction time and temperature, that is to say, complex 15 is kinetically stable complex, while complex 16 is thermally stable one.

它们结构的不同主要有两个方面的影响因素：一、反应的时间和温度的影响，即晶体15是动力学稳定的产物，晶体16是热力学稳定的产物；二、溶液pH值的影响，即晶体15在pH值较大(≈6)的情况下析出，而晶体16在pH值较小(≈4)的条件下析出。

Longshan complex is located at the junction of Qinling and Qilian Orogen, and mainly distributed in Longshan Mountain, the west of Longxian County, which is separated from the Huluhe complex by the Baoping-Shanmen Fault to south, and connected with the Liupanshan Basin by the sub-fault to north. The upper magma is so extensive in this area that only Longshan complex is left as lentoid.

Regarding such complex system, understanding merely the interior partial links in the system is insufficient to explain the system behavior, knowing the interaction of various parts in the system is equally important for the explanation of system behavior, so the theory of complex system and thought of agent based modeling, which bring the microcosmos and macrocosmos together, enlighten the ecosystem modeling. But at present, the following problems should be solved in the ecosystem modeling based on the complex system theory. 1. How to acquire the quantitative indexes of the ecologic factors in the microscopic ecosystem.

对于生态系统这样的复杂系统，以还原分析为基础的传统建模方法遇到了极大的挑战，仅仅了解系统内部的局部环节而忽略事物间的固有联系，远远不足以解释系统的行为，系统各部分之间的相互作用在解释系统行为方面同等重要。
