objective : To introduce a technique of High frequency capacitance pachydermatous treatment clamp sutureless closed hemorrhoidectomy as an alternative to the conventional Milligan open hemorrhoidectomy .

目的 介绍一项较 Milligan 开放痔核切除术更优越的高频电容场钳无缝线闭合痔核切除的新方法。方法选有痔核切除指征的 III 度以上环状混合痔病人 80 名，随机分成高频电容场钳无缝线闭合痔切除组（组 I ： 40 例）和 Milligan 开放痔核切除组（组 II ： 40 例）。由同一痔科医师操作。

These rings, like hidden subway lines, travel at different levels throughout the blocks, connecting public spaces planted within each individual building.

Afterwards, a system of mathematical equations to completely describe the laminar flow in horizontal pipes is obtained.

本文揭示了环状流中核心流体偏心时，核心流体的流量与流体性质、偏心距的关系，对输送高粘流体的工程设计具有重要意义。

Results 20 cases of CT examination had made proper diagnoses,the CT imaging finding about the most of peripheral cholangiocarcinoma included:There was the atactic low density tumour in liver,its borderline was unclear,enhanced scan appearances were irregular peripheral enhancement,centripetal enhancement,and delaying enhancement;There was concretion and dilatation of bile buct in or around the focus;The local envelope of liver was lacunose and the local liver was atrophied,There was abroad putrescence and liquescence in the focus.

结果 20例CT做出了正确的诊断，大部分周围型胆管细胞癌的CT表现为肝内不规则低密度肿块边界欠清，增强扫描表现病灶边缘呈不规则环状强化，有向心性强化的趋势，出现延迟强化；病灶内或周围可见结石，病灶内及周围肝内胆管扩张；局部肝包膜回缩、肝叶萎缩，病灶内大片坏死、液化。

Eustele The STELE arrangement found in most gymnosperms and dicotyledons in which the vascular tissue is arranged into a ring of discrete bundles separated by medullary rays, all contained within a single ring of endodermis and pericycle.

真中柱：发现于大多数裸子植物和双子叶植物的中柱类型，其维管组织由不连续的，被髓射线分开维管束排列成环状。所有的微观组织都包含在内皮层和中柱鞘以内。

Because attraction between agent and reagent at all instants varied, with inverse proportion of increase and decrease, with incessant circular extension and radial reentrance.

因为起作用者和被起作用者之间的吸引力无时无刻不在发生着变化，而这又与持续不断的环状扩张和放射再突入的增减形成反比例。

From the structure, tetraazaparacyclophane is a ring compound with benzene rings connected by nitrogen-containing carbon bridges. It has a well-defined hydrophobic cavity.

四氮杂环蕃从结构来看是由氮杂碳桥将芳香环连起来的环状化合物，分子内具有空腔，该空腔上的芳环呈侧立状，具有一定的深度，并具有疏水性。

In this thesis, we want to describe the new one-carbon chain extension and ring expansion of 1,3-diketones, which is the first report based on our knowledge.

本文在前人的研究基础上，首次发现了开链1，3-二酮增加一个碳原子的自由基链增长反应和环状1，3-二酮增加一个碳原子的自由基扩环反应。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
