Results: The most common locations of PIP were at the margin of both lower lobes and associated with local pleural thickening and adhesion. The density of nodule in which CT attenuation value was 15~60 HU (26.9±13.5HU) was lower than that of PLC. Most of them were round/round-like and irregular in shape. The interior density of lesion was inhomogeneous. The presence of calcification or multiple cavitations, straight margin sign, hole sign and without hilar and mediastinal adenopathy were of great significance in the diagnosis of such kind of disease.

结果：炎性假瘤多位于两肺下叶，邻近胸膜增厚、粘连，病灶密度偏低（平扫CT值15~60HU，平均26.9±13.5HU），与周围型肺癌比较有统计学差异，其形态以圆形／类圆形和不规则形多见，病灶内密度多不均匀，可见钙化及多发空洞，边缘呈平直状、周围见毛玻璃样改变及肺门纵隔无淋巴结肿大等征象对本病的CT诊断有意义。

The first disadvantage of MMI device is wavelength sensitive, which leads to restricted applications. To reduce the wavelength insensitivity in optical network applications, the demand of light source with a specific wavelength is needed, especially for power splitters. For this reason, a wideband criterion for MMI splitter is proposed. The basic principle is based on reducing the interference length difference and making it shorter than the spot size for constructive mode interference. Simulation results show the spectra of proposed MMI splitter is wide enough (1.26-1.61um) to cover the fiber communication band and the size of the splitter is more compact than that of the conventional MMI or Y-branch splitter.

多模干涉元件的第一个缺点为波长敏感，此缺点会限制其在实际上的用途；因元件在网路上的应用时，通常都需要降低波长敏感性，以减低对光源波长准确性的要求；有鉴於此，本论文提出多模干涉分光器的宽频标准；基本原理是建立在缩短其多模干涉区的长度差，并使之小於建设性干涉的光点大小；透过模拟后发现，操作频宽可涵盖光纤通信全波段(1.26-1.61um)，且长度小於Y形分支结构的分光器。

Results Most of 37 cases located at junctional zone between ectocinerea and alba of cerebrum. Shapes of SBM are multiple, such as node, ring form and cyst-solid node were commonly seen. Most of these were accompanied with marked hydropsia. The degree of hydropsia was related with the site of lesion. Different degree enhancement was showed on enhanced CT in all cases.
