剪切混合-
It is found that : ( 1 ) for linear slope, redistribution of incoming energy flux in modenumber space depends on both the modenumber of incident waves and the ratio of the slope of incident wave ray to slope of topography ; both the transmitted and reflected energy flux ( only for supercritical linear slope ) focus near one or two modenumbers ; for supercritical linear slope, the energy flux scattering to higher modenumbers becomes larger and the energy flux to lower modenumbers becomes smaller as the slope of incident wave ray comes near to slope of topography ; ( 2 ) for convex slope, energy flux is redistributed in wide - range modenumbers and also show peaks on lower - modenubers and higher - modenumbers ; ( 3 ) for concave slope, energy flux is also redistributed in wide - range modenumbers, but does not show peaks on higher - modenumbers as supercritical linear slope and convex slope do ; ( 4 ) the total energy flux scattering to higher modenumbers is approximately equal to the total energy flux to lower modenumbers for internal waves propagating over both convex slope and concave slope, which means the concave slope is the same efficient to convex slope in scattering energy flux to higher modenumbers ; ( 5 ) for convex slope, the wave ray reflected from near - critical topography can extend to deep ocean and shallow shelf, while for concave slope, the wave ray reflected from near - critical topography can only extend to limited distance, then meet the topography and be reflected again ; generally the shear of the internal waves reflected twice from concave slope is not enhanced while the enhanced shear does also appear before second reflection takes place, the enhanced shear can bring about intense mixing, so internal waves reflected from concave slope can also produce marked mixing near critical slope
3 、內波在凹地形上傳播時，能通量在模態上的分佈范圍也比較寬，但與凸地形和超臨界線性斜坡地形相比，能通量在高模態上的分佈沒有明顯的峰值。 4 、從總的能通量來講，內波在凸地形和凹地形上傳播時，向高模態散射的能通量與向低模態散射的能通若十地形下內波傳播及內潮生成問題的理論解量近似相等，這意味著二者在向高模態散射能通量方面具有同等效率。 5 、凸地形上臨界點附近的反射，反射波的波射線能夠延伸到深海和陸架，凹地形上臨界點附近的反射，反射波的波射線很快遇到地形發生二次反射，一般來講二次反射后回到深海的波動其速度剪切並不很強，但是在進行二次反射之前的區域，速度剪切仍然很強，因而內波在凹地形上的反射依然能夠在地形附近區域，產生強的速度剪切區，誘發混合。 -
The characteristic of stirring equipment is used a shaking sieve to disperse the adding pure fe or fe203 powder and used a combined stirrer instead of a common paddle stirrer to improve the shear effect to mixing melts. the particularity of fabricating process is the step of holding stirring at a constant high temperature. both of which can improve the even distributing degree of reinforcement phase in pure al matrix
攪拌設備的特殊之處在於使用了振蕩篩分散加入粉末和更換組合式攪拌器來提高對混合熔體的剪切效果，工藝的特別之處在於一定溫度下的保溫攪拌過程，這二者均能提高強化相在純al基體中的均勻分佈。 -
As a whole, efficiency of the chaotic mixing of shear - thinning fluids is worse than of newtonian fluids, but there are different reasons in the two - dimensional and the three - dimensional chaotic mixing in eham
總體上偏心螺旋環流混合器中剪切變稀流體的混合效果不如牛頓流體，但是在二維和三維混沌混合中有不同的原因。 -
Then the author proposed a quantitative method to investigate three - dimensional chaotic mixing and did the comparative studies of three - dimensional chaotic mixing in eham among newtonian fluids, viscoelastic fluids and shear - thinning fluids
其中，提出定量表徵三維eham總體混合效果的方法，並對牛頓流體、粘彈性流體和剪切變稀流體的混合效果進行了比較。
