A major challenge of the heterogeneous wireless networks is how to jointly utilize the resources of different radio access technologies in an efficient manner. Because of the different system capacities of BS/AP and ununiformity of traffic distribution in different cells, quantities of new calls may be blocked in the overloaded cell in some hot spots; whereas its neighboring under-loaded BS/AP have superfluous bandwidth. In order to raise resource utilization of heterogeneous networks, several novel load balancing strategies are proposed, which combine the call admission control and multi-hop routing protocol of ad-hoc network.

异构无线网络的主要挑战是如何高效利用各种接入网的无线资源，针对异构无线网络基站或AP的容量差异及业务分布不均，导致通信热点地区的新呼叫因负载过重大量阻塞，而相邻轻负载小区却有容量盈余的现象，本文提出了几种联合呼叫接纳控制及ad hoc网络多跳路由算法的负载均衡策略，以提高整个异构网络的资源利用率。

Tocopherol has very high physiological activity. Soybean deodorized sludge contains plentiful natural tocopherol. For extracting tocopherol from soybean deodorized sludge, solubility of α tocopherol in supercritical CO 2 is measured. The solubility data are correlated by RBF neural networks model and chrastil model. Relative error of chrastil model is 25.36%. By means of learning and training on RBF neural networks model, the average error of training set is 0.23% and that of testing set is 6.48%....
