CT images of the 6 UAs showed homogenous and low density in comparison with muscles. Of the 6 UAs, 2 (33%) were lobulate, 4 (67%) were regularly round or oval; 1 (17%) had bone septa, 2 (33%) had root resorption of the neighboring teeth, 3 (50%) had cortical perforation. All UAs showed well-circumscribed margins without soft tissue masses. Three UAs were examined by enhanced studies and showed mild to moderate enhancement of the wall. Of the 5 MAs, 3 (60%) showed low to intermediate density as compared with muscles, 2 (40%) showed homogenous and intermediate density; 3 (60%) had bone septa; 3 (60%) showed root resorption or destruction of the neighboring teeth. All 5 MAs were lobulate with cortical perforation, soft tissue masses, and ill-defined margins. All 3 MA5 examined by enhanced studies showed strong enhancement. CONCLUSIONS: SMAs are usually seen in middle-aged patients.

UA病变平扫时与肌肉相比内部都呈均匀低密度，其中4例(67%)呈较规整的圆形或椭圆形，2例(33%)呈分叶状，3例(50%)局部骨皮质有缺损，但未见软组织肿块形成，l例(17%)见不全骨性分隔，2例(33%)邻近牙根有吸收，行增强扫描的3例囊壁均呈轻中度的强化。5例MA的病灶都呈分叶状，且骨皮质均被穿破并有软组织肿块形成，边界不清，其中3例(60%)平扫时与肌肉相比呈等低混杂密度，2例(40%)呈较均匀等密度，3例(60%)可见不全的骨性分隔，3例(60%)见牙根的吸收或破坏，行增强扫描的3例都呈明显强化。

Figure 3. A, Transabdominal scan of the right adnexa shows a complex mass surrounded by pelvic structures containing several round areas of loculated fluid that vary in size and are separated by a thickened band or adhesion, simulating a tubo-ovarian abscess or complex. B, Transabdominal cross-sectional scan shows the 2 loculated fluid areas posterior to the uterus separated by a thickened adhesion band.

图3 A，右侧附件区经腹部扫描显示被盆腔结构环绕的混合性肿块，其内有数个圆形的局限性积液，其大小不等，被增厚的束带或粘连分隔，象是一个输卵管-卵巢脓肿或复合体。B，经腹部横切面扫描显示子宫后方的2个局限性积液区，被一增厚的粘连束带所分隔。

Figure 2. A, Parasagittal scan at right adnexa shows loculated fluid with several septations with echogenic nodular masses representing peritoneal thickening or omental thickening. B, Transvaginal scan of the left adnexa shows a poorly defined complex mass representing peritoneal or omental thickening.

图2 A，右侧附件区的矢状旁面扫描显示积液呈多房性，有数个分隔，结节性肿块表明腹膜增厚或网膜增厚。B，经阴道扫描显示左侧附件区边界模糊的混合性肿块，表示腹膜或网膜增厚。

By means of FTIR,SEM,DSC,TGA and XRD,we studied the microstructure,particle shape,meltage temperature,decomposition temperature and crystal degree,and gained better understanding about influences of different degrees of substitution on microstructure and thermal property of starch acetates.

用傅立叶红外、扫描电镜、差示扫描量热、热失重和X射线衍射测试技术对淀粉醋酸酯的结构、形貌、熔融温度、分解温度和结晶度进行表征，分析了不同取代度对醋酸酯淀粉的热性能及其结晶结构的影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
