Imaging findings of expansile lesions of the thymus .

胸腺膨胀性病变的影像学表现。

The tumor is an eccentric , expansile , lytic mass with extension into soft tissue along with overlying reactive new bone formation .

肿瘤呈偏心性生长，可见膨胀的可溶性肿块，向反应性新生骨周围的软组织蔓延。

And in the recent years , the difference has a expansile trend . So it is necessary to choice some representative aspects in the difference to research and analysis .

而且近年来，这种差异有逐渐扩大的趋势，因此，从这些差异中选取有一定代表性的方面加以分析研究就显得很有必要。

The present status of activated carbon fibers , carbon nanotubes and expansile graphites as the electrode materials for electrical double-layer capacitors were discussed respectively .

对目前已用做电双层电容器电极材料的活性碳纤维、纳米碳管和膨胀性石墨的研究情况分别做了论述。
