Objective To compared the divergence among physical palpation,mammography and ultrasonography.

目的 肿瘤大小是乳腺癌临床分期中的决定因素，为此我们比较了物理查体、X线检查和超声波检查在乳腺肿瘤测量中的差异。

The key to apply CCD to implement mammography is to improve the coupled efficiency of light from scintillation screen to CCD, and it is necessary that the image system has a large relative aperture and adopts close imaging, which makes the CCD image seriously distorted.

为提高由闪烁屏到CCD的光耦合效率，减小大相对孔径和近距离成像造成CCD图像严重失真，提出一种有效补偿图像失真的预处理方法。

Mammography is the most common imaging modality in detecting and screening breast tumor. However, for better image contrast and spatial resolution, the patient's exposure to X-ray radiation is highter than that of the ordinary roentgenography.

乳房摄影是用来侦测与筛检乳房肿瘤最常用的诊断工具，为求得到较佳的软组织对比与解析，使用的X光照相条件比一般常规摄影具有较高的放射线剂量。

Breast cancer is the fourth leading cause of cancer death for Taiwanese women. X-ray mammography is currently the most effective method for an early diagnosis of the breast cancer. The existence of spicules is one of most important visual signs for breast cancer diagnosis. Spiculation is a stellate distortion caused by the intrusion of breast cancer into surrounding tissue. In general, malignant tumors appear with rough and complex boundaries or contours, whereas benign masses present smooth, round, or oval contours.In this paper, we present a technique to detect the contours of spiculated lesions from the regions of interest in a mammographic image.

中文摘要乳癌是是我国妇癌症死亡主因的第四位，乳癌诊断程序中，乳房X光摄影为临床上医生诊断乳癌的利器，在诊断乳房摄影肿瘤的影像时，可用特徵决定为良性或恶性肿瘤，良性肿瘤通常会呈现圆滑的特徵，而恶性肿瘤则呈现星状或不规则不平滑特徵，这种星状或不规则不平滑特徵组织，称为星状物肿瘤，指的是肿瘤周围的乳腺组织，因星状物往外侵犯的关系造成的变形，星状物的存在是恶性肿瘤判断的依据。

Masses are usually difficult to be detected as they often superimpose on dense structured background of mammography.

在乳腺X线图像中，肿块大多埋没在复杂的、高密度的腺体背景中难以检出和识别。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
