Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.

Results The supratentorial lesions involved the occipital lobe in 4, frontal lobe in 3, fronto-occipital lobe in 2, temporo-occipital lobe in 3, lateral ventricle in 1 case and the saddle region in 1. All the lesions were large in volume and most of them presented heterogeneous signals in MRI. Of the 14 cases, 12 showed cystic degeneration and necrosis, 2 had hemorrhage and 6 showed signs of emptied small blood vessels. Twelve cases had heterogeneous enhancement and 2 had moderate enhancement. Pathologically, 10 cases of neuroblastomas were identified, along with 3 ganglioneuroblastomas and 1 atypical rhabdoid tumor.

Combined crystallization kinetics analysis obtained via rheometry and morphological observation of crystals growth performed on POM, two different mechanisms of shear-enhanced crystallization for PP/ grafted MWCNTs composites were suggested:(1) at low temperature, strong heterogeneous nucleation plays a dominant role on the. crystallization behavior, which would be saturated at a higher filler content, and the effect of shear-enhanced crystallization was weak;(2) at high temperature, the effect of heterogeneous nucleation was substantially depressed, and the crystallization of the composite was obviously accelerated by pre-shear and the thread-like crystallites were generated earlier than the spherulites.

结合流变测试结果和热台偏光显微镜观察的结晶形貌发展过程，对于PP／G—MWCNTs体系得到了两个不同的剪切影响机理：(1)在低温条件下，强烈的异相成核作用对结晶行为的影响占主导优势，而剪切作用对结晶的影响十分微弱，同时，在填料含量较高是，异相成核作用具有饱和性；(2)在高温条件下，异相成核作用被抑制，复合体系的结晶主要受到预剪切作用的影响，并且纤维状晶体较球晶更易生成。

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。
