No aorta-clamping is a feasible,effective and safe technique for myocardial protection during CPB.The technical skill of preventing air embolism should be emphasized.

体外循环下不阻断升主动脉心内直视术是临床效果满意，安全有效的心肌保护方法，心腔气体排出的技术要予以强调。

Objective: To invent an intracavity air sac urinary catheter to meet the clinical requirement.

目的：研制一种适合临床需要的腔内气囊导尿管。

There is obvious rotary movement of air in valve cavity.

Results There were 28 cases with anastigmatic recurrence, the signs on CT were mass a rounding anastigmatic. There were 20 cases recurrenced on thoracic stomach, presented mass in mediastinum, the wall of thoracic stomach becaming thickness and mass in the thoracic stomach formed.

结果 吻合口复发28例，在CT片上表现为吻合口区不规则肿块影；胸胃复发20例，在CT片上表现为纵隔内结节或肿块，胸胃腔变窄，胸胃壁不规则增厚，并形成软组织肿块影。

MethodsThe clinical data of 43 patients who underwent covered stentgrafting for dissection of aorta were analyzed.

对采用支架血管腔内治疗的43例主动脉夹层病人的临床资料进行分析。

First of all, large-format cameras allow flexible adjustment, by shifting up, down or sideways of the front and/or back of the camera, and secure great apparent depth of field to obtain images freely. This provides photographers a sound basis for art creation. With relatively larger films, it is possible to obtain more raw data, which illustrate all the tiny details in the image.

首先，大画幅相机具有灵活移轴调整功能，通过对镜头的移轴和皮腔部位的倾斜、偏摆来调整视点，可以在清晰区域内获得自由图像造型，为摄影师们提供了广阔的创作空间；较大尺寸的底片，可获得大面积的RAW的数据，能很好地表现影像中极为细微的部分。

The inpocketed vegetal pole cells develop into a sheet of cells which grows upward and eventually encloses a cavity, the archenteron

内褶的植物极细胞生成一片向上生长的细胞，并最后围成一个腔，即原肠。

Methods 63 cases of coxa arthropathy associated with AS were divided into two groups,experimental group and control group.Both groups received a basal treatment of taking sulfasalazine and nabumetone.In EG intra-articular injection of sodium hyaluronate and was carried out once a week in 33 patients with coxa arthropathy associated with AS.Each case received 5 injections in all,only in first injection combined with compound betamethasone.

63例强直性脊柱炎伴髋关节病变患者随机分为两组，均在给予柳氮磺吡啶1.0g，每日2次及萘丁美酮1.0g，每日1次的基础治疗上，试验组患者进行玻璃酸钠和复方倍他米松髋关节腔内注射，每周1次，第1周同时注射两种药物，后第2～5周，仅注射玻璃酸钠，而对照组仅于疗程第1天给予复方倍他米松肌肉注射1次，连续5周为1个疗程。

The model involves an atomic beam composed of three level atoms as shown by the energy diagram, which is injected into a cavity.

在这一模型中，在腔内不要求有从基态能级到其它能级的非相干泵浦。

Valve with is it regulate valve suit,flow of function to have.can be suitable for the occasion needing to control flow while being built-in,can also slow down the pressure head of the fluid.

阀腔内装以具有调节流量功能的阀套，可以适用于需要控制流量的场合，亦可以减缓流体的压力头。

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。
