Methods The CT data of 12 cases retroperitoneal Liposarcoma with verifield by pathology were reviewed retrospectively.To analyze the CT manifestation.

回顾12例经手术病理证实的腹膜后脂肪肉瘤的CT平扫和增强资料，12例均行CT平扫，7例加作增强。

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。

The diameter of primary sarcomatoid hepatic carcinoma ranged 5 -10 cm. Huge cystic-solid lesions with irregular septa were found in 2 patients, multiple nodulated soft tissue shadows in 4 patients, and inhomogeneous low-density lesion with unconspicuous enhancement in the other 2 patients.

6例CT平扫表现为囊实性低密度影，其内见条状分隔影(2例)及散在分布的条状、结节状软组织密度影(4例)，增强扫描呈不均匀强化，余2例CT平扫表现为不规则低密度影，增强扫描未见明显强化。

Although the swept-scan technique is currently employed in high-frequency ultrasound systems, the continuous transducer movement may have nonnegligible effects on accuracy of velocity estimation.

虽然扫掠式扫瞄已应用於目前的高频系统，然而探头的连续移动对於流速的估计有著不可忽略的影响。

Sherburn run his eye slow along the crowd; and wherever it struck the people tried a little to outgaze him, but they couldn't; they dropped their eyes and looked sneaky.

歇朋朝群众的队伍缓缓地扫了一眼，眼神扫到那里，人群试图把它瞪回去，可是不成。他们把眼睛向下垂着，显出一派鬼头鬼脑的神气。

And he fell on the ground and heard a voice saying to him, Saul, Saul, why are you persecuting Me?

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
