Results MRVE of normal arteries can be seen round and smooth.We can see4～6grades of branches of the cerebral arteries by its opening;Arteriosclerosis detectedwith MRVE showed that the ramose number of blood vessel reduced;Vein were seen as a wide and flat canal.

结果 正常脑动脉血管MRVE表现为圆形光滑的管腔，可看到其4～6级分支血管的开口；动脉硬化在MRVE上表现为血管分支开口数目的减少；静脉血管表现为宽扁的光滑管腔。

The options of treatment for abdominal aortic aneurysm include traditional procedures and endovascular aneurysm repair.The reintervention rate is higher in EVAR than in traditional procedures.

腹主动脉瘤传统手术及腔内修复术后的再手术应根据不同原因采取相应策略，腔内修复较传统手术有较高的再次干预率。

Four laser beams as 40K and 87Rb cooling and repump lights are obtained by using acoustic optic modulators to offset the frequencies from the three ECDL lasers. Four light beams with the different frequencies are injected into four slave lasers for injection locking, then Rb cooling light, K cooling light and K repump light are injected into a semiconductor tapered amplifier in a master oscillator-power configuration.

采用三台外腔光栅反馈半导体激光器、四台注入锁定激光器和一台半导体激光放大器组成激光系统，三台外腔光栅反馈半导体激光器通过声光调制器产生四束光，分别作为40K和87Rb原子的冷却光和再抽运光，四束不同频率成份的激光分别注入锁定四台从激光器，然后Rb cooling光、K cooling光和K repump光再同时注入半导体激光放大器进行放大。

Methods Twenty-five cases of giant PLCs, with a mean diameter of 14.78cm, were evaluated. All of the tumors involved the main hepatic veins and /or retrohepatic vena cava. Before resection the tumor was fully exposed and an occluding tape, when neccessary, was placed around the vena cava.

25例累及第二第三肝门的肝癌，平均肿瘤直径14.78cm，分别压迫主要肝静脉根部或/和肝后腔静脉；进腹充分暴露肿瘤后在间歇性第一肝门阻断下切除肿瘤，切肝前根据需要预置腔静脉阻断带备用。

The SiO_2 microdisk resonators with vertical sidewall have been achieved with RIBE in the world. 4 Research of the silicon etching.

在国际上首次通过RIBE得到具有垂直侧壁的SiO_2微谐振腔。4对采用适宜的Si刻蚀方法得到SiO_2微盘谐振腔支撑进行实验研究。

At same time it collects the pr essure signal of Servo-cylinder, it finds that the overflow valve pr essure sets too high between the servo valve and Rodless cylinder servo cavity, Tanks should not stress-free cavity under unloading, According to the fuel tank pr essure signal.

摘 要：本文针对某热轧厂横切线上的主要设备矫直机在矫直高强度，厚规格产品时，当负载受到外扰动时，矫直机传动轴经常断，工作辊轴承经常损坏现象，于是对伺服缸压力信号进行采集，发现装在伺服阀出口和伺服缸无杆腔之间的溢流阀压力设置过高，油缸无杆腔压力不能卸荷。

Results］All 18 cases were observed the real and the false cavity satisfiedly in two kinds of scanning.

结果］18例患者MSCT主动脉全程增强扫描均满意观察到真、假腔的大小、范围、主要分支是否受累。18例采用心电门控扫描显示胸廓入口至主动脉裂口水平的主动脉真假腔与全程增强扫描一致。

Objective: Generalize the technique of puncture the serositis effusion and retention of central venous catheter in serositis.

目的：推广经皮穿刺并浆膜腔内留置中心静脉导管引流浆膜腔积液的诊疗技术。

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%.
