Firstly the k-e two-equation turbulence model is used in numerical simulation of the flow field ,compared with the practical measures and tests, good accordance achives. This method can bring great convenience in analyzing aerodynamical field of boiler. Secondly the method of ash-composition, ash-melting-point, XRD is used in analyzing the phase transformation in the course of dynamic slagging test, so we can describe the process of slagging comparatively accurately. Last this paper introduces a kind of fuzzy mathematics model which comprises an assemblage combined by seven change factor.

接着采用标准k—ε双方程模型对炉内冷态空气动力场进行了数值模拟，并与实际锅炉燃烧器冷态调试试验结果对比，结果吻合较好，这为我们分析炉内流场提供了参考；其次对锅炉静态、动态特性试验，采用灰成分分析、灰熔点测试及X光衍射物相分析方法，较为准确的描述了实际锅炉结渣过程；为了准确的判断出水煤浆的结渣倾向，本文对锅炉结渣的七个影响因素提出了模糊综合判断模型，正确的反映出了该水煤浆的结渣倾向。

Second, the afterbody of the cuboid is modified step by step in 9 models to model flow wake at rear end and...

利用荧光黄纳及片光在水槽中对具有不同收缩比的民机后体的复杂绕流进行流动显示，探讨了后体的分离尾涡特性及参数影响，实验发现后体收缩比改变时对应了两种典型的尾涡流态，即稳定流向尾涡和周期性尾涡，并进一步探讨了尾翼对后体尾涡的影响。

In the view of the description of Secularity and Afterworld in the Quran and the Sunnach, it analyses and induces the concrete contents and thinking.

第二，从伊斯兰"两世"思想的基础、体现及精神实质的角度进行分析、研究，并探讨伊斯兰哲学各个流派对"两世"思想的不同阐释。

The unsteady flow s in a agitator are calculated numerically, and compared with the author′s experimental data.

研究了搅拌器内非定常流场的分布，并与实验结果做了比较。

In addition, because of the interleaving of top and bottom nappes, there is no bump in the air, the finite width of spillways can be fully utilized, and flood discharging atomization caused by bump of nappes can be weakened.

而且，表、深孔水舌在空中交错穿插，不发生空中碰撞，可充分利用有限的溢流宽度，并减少因水舌空中碰撞而导致的泄洪雾化的增强。

For this, began model airscrew to sing sound the experiment research that eliminates a method, the sorts voice from surface of lamina of change model airscrew angle in the experiment designed a few kinds of disappear to call plan, finish sound measurement of a confusion of voices to experiment.

为此，开展了模型螺旋桨唱音消除方法的试验探究，试验中从改变模型螺旋桨叶片表面流态的角度设计了几种消唱方案，并完成噪声测量试验。
