结果：中耳癌的CT特征：①表现为以中、下鼓室为中心的软组织密度灶，密度均匀，CT值50HU左右，外耳道及咽鼓管早期受累；②呈溶骨性骨质破坏，形态不规则，边缘无骨硬化表现，外耳道后壁破坏较前壁严重；③病灶侵入颞叶，形成肿块，灶周脑水肿不明显；④增强扫描见病灶有中度强化。结论：CT能确定中耳癌的存在及精确显示肿瘤累及范围。

After the tested N gas components are led into the spectrograph via sampling probe and pipeline, the spectrograph obtains the transmittivity data in the scanned wave number or wavelength range and transmits the data to the computer, the computer extracts the effective characteristic quantities as the input to the parallel supporting vector machine algorithm module, and the supporting vector machine outputs the multiple component gas concentration values.

被测的N个多组分气体经气体采样探头与连接管路导入光谱仪，由光谱仪获得扫描波数或波长范围内各波数或波长对应的透射率关系给出光谱数据经数据传输线进入计算机。进入计算机内的光谱数据由软件的数据预处理模块提取有效的特征量，作为支持向量机并行算法模块的输入，支持向量机并行算法模块的输出为N个多组分气体浓度。
