It has a 'soft' neon tube ozoniser which does not produce NO fro air feed gas and therefore does not suffer from nitric acid production if the air feed gas is not totally dry and it does not produce an error in the NO2 reading due to a difference in window contamination due to the filtering effect of the NOx converter.

Signal Model 4000VM 提供 NOx/NO/NO2 连续输出，每3秒钟刷新一次数据，等同于 ECO 双反应室设计，它有一个氖管臭氧发生器，不会经由空气原料气生成 NO ，因此当空气原料气不完全干燥的情况下也不用担心产生硝酸，由于 NOX 转化炉产生过滤效应但污染物是在不同的窗口，所以 NO2的读数不会出现误差。

The results show that the tangential velocity distribution in the annular space shows a typical feature of strongly swirling flows and it consists of quasi-free vortex area and quasi-forced vortex area.

由于流体与双侧壁面之间的摩擦造成能量损失和湍流能量耗散，导致最大切向速度不断衰减且位置沿轴向向下逐渐向提升管外壁移动，同时涡量传递造成外部的准自由涡区逐渐增大，内部的准强制涡区逐渐缩小。

Group 1 with fixation of facet joint screw had a significant increase in stiffness for extension, bilaleral bending, and colockwise rotation.

经侧后方斜向植入的单枚椎间融合器加上小关节突螺丝钉内固定融合术，在提供充分椎管减压的同时，具有损伤小、脊柱后部稳定性好、术中对马尾及神经根牵拉轻的优点，可以比较理想地取代后路双枚融合器椎间融合术。

The erosion-corrosion mechanism of AISI1020 in artificial sea water with or without 1000×10-6 silica sand under sudden pipe expansion condition was investigated through weight loss test, surface morphology observation,local flow regime measurements and electrochemical measurements at specific position.

利用新近研制的双相流冲刷腐蚀激光多普勒实验装置，通过失重测试\表面形貌观察、局部流速流态测试和典型部位的电化学测试，研究了突扩管条件下碳钢AISI1020在单相及含砂人工海水介质中的冲刷腐蚀机理。

Results: Scans of 3D-FIESTA sequence combined with post-procession could precisely show labyrinth, nerves and vessels in inner ear and internal auditory canal, as well as the relationship between nerves and vessels around. As to the ability to evaluate nerves in IAC, MPR and VE was superior to MIP; As to the ability to display semicircularesin and cochlea, MIP was the same as double oblique MPR; It was important for VE and oblique sagittal MPR to display the position of foramina nervosa of IAC.

结果：3D-FIESTA序列扫描结合MPR、MIP和VE重组对内耳迷路及内听道内神经及血管显示清晰，能够清晰显示两者之间的关系，MPR和VE重组对神经的显示优于MIP重组，MIP对半规管显示与双斜面MPR并无明显差别，VE和斜矢状面对于内听道内各神经孔的位置关系具有重要意义。
