At the same time, when the thickness - diameter ratio was larger than 1, it has little influence on the discharge coefficient for the hole configuration, but when the thickness - diameter ratio was less than 1, the discharge coefficient of the hole with across arrangement is higher than that with sequence arrangement
同時，在氣膜孔厚徑比大於1時，氣膜孔的排列形式對流量系數的影響不大，當厚徑比小於1時，叉排氣膜孔的流量系數要高於順排氣膜孔的流量系數。 -

掘進巷道炮眼布置計算機輔助設計 -
The surface of natural fracture ( crack ) is parallel to the orientation of maximum principal stress. the principle orientation of anisotropic permeability reservoirs agrees with the orientation of the maximum principle stress. many engineering problems ( e. g. bore - hole stability, casing deformation failure during drilling, reasonable arrangement of wells, the optimum design of hydraulic fracture and so on ) are influenced by the in - situ stress orientation
天然裂縫面和裂隙面與最大主應力方向平行；在各向異性低滲透率油田中主滲透率方向與最大水平主應力方向趨向一致：在鉆井過程中井壁穩定性，套管變形和損壞，油田開發井網合理布置、水力壓裂優化設計等都與地應力方向有關。 -
Firstly, for jet array impingement cooling, the effects of the distance of adjacent holes, the impinging distance and jet reynolds number on heat transfer characteristic at the target wall are summarized under staggered holes arrangement and the same hole diameter. and then, the numerical simulation of inclined multi - hole film cooling has been studied. the influence factors examined in this case include blowing ratio and the distance of adjacent holes
首先通過對射流沖擊冷卻方式的研究，分析了相鄰孔間距、沖擊間距以及射流入口雷諾數對沖擊靶面換熱系數的影響情況，然後對多斜孔冷卻方式進行了數值模擬，重點探討了吹風比和相鄰孔間距對絕熱溫比與壁面換熱系數的影響規律，最後，針對沖擊-發散復合冷卻流場的計算物理模型，研究吹風比、相鄰孔間距的變化對沖擊-發散復合冷卻流動與傳熱特性的影響。 -
The influence of specific charge, hole arrangement, charge structure, stem length, millisecond interval and ignition mode on the yield of the blasted boulder is analyzed some measures to lower boulder yield in deep hole blasting of underground mine are presented through the optimization of blasting operation parameters as follows : lowering deep hole blasting effect of geology structure, rationally determining specific charge, using technique of wide - space small burden blasting, technique of manifold charge structure and technique of millisecond compression blasting, strengthening the management of boring construction and blasting construction
