Under different structural parameters of exit tube,including the inner diameter and the structure shape,the separation efficiency and pressure drop of the guide vane cyclone tube were measured by comparative experiments and the flow field in the guide vane cyclone tube was measured by an intelligent five-hole pilot tube.

通过对比实验测定了不同排气结构下导叶式旋风管的分离效率及压降，同时用智能型五孔球探针测试仪测定了不同排气结构的旋风管内流场分布，结合性能实验与流场测量的结果，研究了排气芯管内径及其结构型式对分离性能的影响，为旋风管结构优化和开发及其分离机理的研究提供了一定的实验基础。

While Ni(NO3)2 and Mg(NO3)2 were used as ushers of the catalyzers, carbon nanotubes were prepared by catalyst-assisted CVD in different ratios of gaseous mixture, which were analyzed with TEM, SEM and Raman spectrograph.

将Ni(NO3)2-Mg(NO3)2体系作为催化剂前驱体，在不同气源比例下用CVD催化裂解法制备纳米碳管，用SEM、TEM和喇曼光谱对其进行了表征和分析，制备出完整性好的纳米碳管。

While Ni(NO3)2 and Mg(NO3)2 were used as ushers of the catalyzers, carbon nanotubes were prepared by catalyst-assisted CVD in different ratios of gaseous mixture, which were analyzed with TEM, SEM and Raman spectrograph. The results show that carbon nanotubes prepared in CH4/H2=250/50=5/1 are pure and intact.

The experimental investigation demonstratesthat (1) the critical perforation energy of pressure pipelines (D/H=15) with pressure OMPa under lateral impact of flat-nose and spherical-nose indenters ranges from 2~3%,the critical perforation energy of empty pipelines is higher 1 ~2% than pipelines filled in water without pressure.

实验研究结果表明：(1)当管梁内注满水，预加工作内压P=0MPa时，对于径厚比D／H=15的厚壁圆管，在平头弹体和球形弹体两种弹体冲击作用下临界穿透破坏能量的降幅在2～3％之间：锥头弹体冲击厚壁空管的临界穿透能量比充水预加内压为P=0MPa的圆管高1～2％：(2)充水管道的预加内压提高，临界穿透能量有一定降低。

Methods A total of 30 patients receiving open cholecystectomy under the general anesthesia and epidural anesthesia in our hospital were selected.The right internal jugular vein and femoral vein catheterization was performed after the anesthesia induction and intubation to continuously monitor CVP and the inferior vena cava pressure.Meanwhile, the changes in CVP, MAP, HR, IVCP before abdominal opening,upon pulling gallblad-der as well as 5 min, 10 min and 15 minutes after the opening of deep retractors were observed, recor-ded and compared.
