腔形成

Objective To evaluate the clinical application of permanent vena cava filter in patients with deep venous thrombosis.

目的探讨下肢深静脉血栓形成患者植入永久性腔静脉滤器的临床应用。

The paper reviews the causes of formation of cavitation and embolism, its mechanism and repair.

本文对腔隙和栓塞的形成的原因、机理及其恢复进行了综述。

The effect of plasma densities and plasma collision frequencies on the field amplitude,field phase and reflection coefficient of the cavity is computed and analysed.It is clearly shown that the absorption of plasma to microwave is increase...

数值计算结果表明，在一定的等离子体密度下，随着等离子体碰撞频率的提高，等离子体对微波场的吸收增大，此种开放式的结构可有效地在腔中形成有利于微波等离子体产生的驻波场。

In practice, this is because just before the out of teeth, root is not fully formed, the pulp cavity and apical foramen are large, thin apical cementum caused.

实际上，这是因为之前出牙，根尚未完全形成，牙髓腔和根尖孔大，薄根尖牙骨质造成的。

There was, however, shorter root formation and a narrower root cavity compared with the contralateral incisor.

然而，也有人短，根系的形成和狭义根腔较对侧门齿。

Furthermore, the structures of the complexes are strange. The tripodal ligand H〓L〓 form a 2: 2 ring-like binuclear complexes [Eu〓·L〓·6DMF] ·CH〓OH·DMF with Eu〓 in DMF. Two DMF molecules are accommodated in the ring and coordinate with Eu〓.

此外配合物的结构还比较特殊，三足配体H〓L〓与铕的配合物在配位能力较强的溶剂DMF中形成环状的2：2型双核配合物[Eu〓。L〓·6DMF]·CH〓OH·DMF，环状空腔刚好能够把两个配位的DMF溶剂分子包在里面。

A coronary thrombosis is seen microscopically occluding the remaining small lumen of this coronary artery.

冠状动脉血栓形成镜下图，血栓使仅有的很小的内腔闭塞。

The colour of eggshell is formed by pigment sediments that are formed in the reproduction cavity.

蛋壳颜色是蛋壳在生殖腔中形成的色素沉积而成。

RESULTS On the experimental side, there was new bone formation in the bone medullary cavity, the endosteum and the section surface of the cortex at 2 weeks. At 4 weeks, at the center of the blood clot in the tube there was new bone formation and bone defect was completely healed at 8 weeks.

结果 实验侧术后2 周即在骨断端髓腔、骨内膜及皮质断面处有新骨形成，并长入管内血肿，术后4周新骨长入血肿中心，8周完全骨愈合。

The fiber endface and diaphragm form an etalon cavity. The entire sensor head is only 125μm in diameter.

单模光纤末端面和薄膜之间形成F-P干涉腔，整个传感头外径只有125μm。

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。
