It is shown that the ADFVLN, which has lower losses, high off-design performance and reliability, is superior to the vaned nozzle as the first stage and it also has more advantages than the early AFVLN, such as lower losses and less skewed boundary layer near the inner ring ect..

研究表明，这一新型轴流无叶喷嘴不仅具有原来同类喷嘴的优良性能，而且双出口结构和内环旋转的特点，使其流动效率明显提高，并省去两块隔板，缩短了机组的轴向尺寸，具有较高的工业应用价值。

By Ensemble-averaged Method, the mean field was got to show the 3D structure of flow. By Phase-locked Averaged Technique, the periodic mean field was got to reflect the periodic unsteady characteristic. The 3D structure and the periodic unsteady characteristic of the unsteady flow within the vaneless and vaned diffuser were discussed through analyzing the mean field and the periodic mean field.

离心风机扩压器内非定常流动的实验研究本文完成了离心风机两种结构条件下无叶扩压器、有叶扩压器内部的非定常流动瞬态全流场的实验测量，获得了不同运行工况下PIV的瞬态流谱，为研究扩压器内部非定常流动提供了基础实验资料。

What for the use family can be safer and reliable uses this mould pump , and this unit especially has developed just the dismantling type structure mould , and it gives birth to GDL excepts holding in arms and all merits of GDLS , more more your changes mechanically close etc Yi Sunjian has provided filling more further just , and prompt and the person who saves effort the way makes a mould pump more not have worrying about operating and maintenance.

为了使用户能更加安全、可靠的使用该型泵，本单位特别研制了便拆式结构型，它除拥育GDL、GDLS的一切优点外，更为您更换机械密封等易损件提供了更加充便，快捷、省力的途径，使本型泵更无忧运行与维护。

In America, where the social safety net was flimsier, there were far fewer regulatory rigidities and people were more willing to move, so workers responded more flexibly to structural shifts .

美国的社会安全网（注6）更是不堪一击，几无协调、制度刻板，人们更愿意四处走动，因此劳工对结构转变的反应表现出更大的灵活性。
