管式熱交換器.管心距管薄板的鉆孔直徑.擋板和支承Actually, the mask and openings are not really necessary; the mirror alone could serve as aperture.
其實，擋光板及其上的開孔都是不必要的；單單反射鏡本身就可以起小孔的作用。Slabs are concreted complete with ducts and openings framed with metal aprons welded to slab reinforcement and intended to accommodate columns
樓板用混凝土澆注成整體，其上留有用金屬擋板圍成的孔道和提升環，它們和樓板配筋焊接在一起，以備將柱子套入其中。The experimental results show that the distribution of the radial static pressure behind the model cascade can be controlled by changing the diameter, number and distribution of the holes at different radius of the full circled backboard with the holes properly ， and the experiments variable enthalpy drop in the model cascade can be realized by using out - circled backboard or in - circled backboard which are set on the different distances from the trailing edge of the model cascade
實驗結果表明，適當選擇全環鉆孔擋板不同半徑處的鉆孔率、鉆孔直徑與分佈，可調節靜葉后徑向靜壓分佈，採用外環或內環擋板，並將其分別置於靜葉的近、中、遠下游，可實現靜葉柵的變焓降實驗。When the punched baffle is proper in length, the small holes are in staggered arrangement and the punched ratio gradually increases from the central axis to the boundary along the baffle length, the performance of flow distribution in the plate - fin heat exchanger is effectively improved by the optimum design of header configuration
從實驗對比分析中得出，當擋板小孔呈錯排分佈、開孔率沿擋板的中軸線向兩側逐漸增加、且總開孔率達到50 %左右的時候，在相同的入口條件下，不均勻系數由原始封頭的1 . 210降至0 . 209 ，最大流速與最小流速之比由23 . 163降至1 . 756 。Based on some discussions on the mathematic model set up for the cathodic protection potential field, a two - dimensional boundary element method ( bem ) is developed, and by using which, a study on the shielding effect resulted from some typical inner structures such as the reinforcing elements and the partition walls with man holes on distribution of potential and current density in the cathodic protection is performed. the investigated parameters which affect the shielding effect in the calculating model include : the height and thickness of the reinforcing elements, the distance between the anode and the reinforcing elements, and the diameter of man hole on the partition walls, and so on
本文在討論了陰極保護電位場問題的數學模型的基礎上，以二維邊界元法對陰極保護問題中的電位及電流密度分佈進行了模擬計算，重點對船舶壓載艙中的典型結構如加強筋、人孔等在陰極保護中所產生的屏蔽效應進行了分析和研究，通過對不同高度、厚度的擋板及不同孔徑的帶孔板所產生的屏蔽效應進行模擬計算，首次得到了一些對實際工程設計具有重要參考意義的見解。It is found that the fluid flow maldistribution is very serious for conventional header while the improved header configuration with punched baffle can effectively improve the performance
實驗結果表明，原始封頭內部的物流分配存在嚴重的不均勻性，採用添加打孔擋板之後的改進型封頭，流場的不均勻性有了很大的改善。分享友人
