The blade inner channel cooling is a complex convection - conduction coupling problem. this thesis build a three - dimension. compressible turbulence model, and give a general solve method. with the geometrical model of the glossily rectangle straight channel, the rectangle straight channel with in - line arrays disturb plates, the rectangle straight channel with staggered arrays disturb plates, the rectangle straight channel with slant disturb plates, this thesis compute the flow and heat transfer condition when the cold air path though these channels, and gain the temperature field, pressure field, velocity filed, in addition. this thesis also analyze the influence of the different channel height, the different channel materials, the different channels, and gain the function relation between he nusselt number, friction factor and reynolds number. this thesis is emphasis on the new heat transfer enhancement structure, that is, disturb plates, with the comparison with the glossily channel and channel with pin fins, the heat transfer enhancement effect of the former is better, and the conclusion can be used in the design of aircraft blade
葉片內部通道冷卻是一個復雜的對流?導熱耦合傳熱問題，本文在分析葉片內部通道冷卻的流動與傳熱情況的基礎上，建立了三維、可壓縮紊流的物理模型，得到了通用的求解辦法；利用不帶擾流片的矩形直通道、帶順排擾流片矩形直通道、帶叉排擾流片、帶傾斜擾流片的矩形直通道的幾何模型，計算了冷卻空氣通過這幾種通道時的流動與換熱情況，得到了各種不同情況下計算區域的溫度場、壓力場、速度場；在此基礎上分析了不同的通道高度、不同的葉片通道材質對葉片內部通道冷卻的影響，並整理得到了各種通道形式下，努謝爾數和阻力因子與雷諾數的函數關系；本文重點研究了新型的葉片內部通道冷卻強化傳熱措施?帶擾流片的內部冷卻通道的強化傳熱效果，通過與光滑矩形直通道、帶針肋通道的冷卻效果的比較，表明了這種新型鮚構的優勢，對于葉片內部通道冷卻結構的設計可以起到指導的作用。 -
However, the moon s path is tilted about 5 to the ecliptic, making the alignment of the sun, the earth and the moon in a straight line a relatively rare case. only when the sun and the moon are close enough to the nodes crossing points of the ecliptic and the moon s paths during full moon, a lunar eclipse can occur
要注意的是，由於太陽和月球在天空的軌道稱為黃道和白道並不在同一個平面上，而是有約5度的交角，所以只有太陽和月球分別位於黃道和白道的兩個交點附近，才有機會連成一條直線，產生月食。 -
First, identify the constellation where the radiant lies. watch carefully the path of the meteors. if necessary, you can trace back the path as an imaginary straight line to see whether it intersects with the radiant
首先在星空中找出輻射點所在位置的星座，留心那些流星在天空的軌道，看其延長線是否落在這個輻射點的天區上。 -
Because each path takes the form of a chord ? a straight line connecting two points at the edge of the sun ' s disk ? astronomers could measure the angular shift between the paths by comparing the durations of the transits
因為每條路徑都是一條弦（連接太陽盤面邊緣兩點的直線） ，天文學家便能比較凌日持續的時間，而計算路徑間的角差。 -
Primarily there are two aspects : 1 ) the calculation model of the value of land classifying units - - model of time distance attenuation. in the calculation model of the value of land classifying units, author brings forward the model of time distance attenuation. in this model adopting the network analysis, and by establishing the road network, and proceeding path analysis, computing the time distance, then proceed the exponential attenuation or straight line attenuation on time distance, get the value of influence factor of the land classification unit
主要有兩個方面： 1 、定級單元分值計算模型? ?時間距離衰減模型在定級單元分值的求取模塊中，提出了時間距離衰減模型，模型中採用網路分析的方法，通過建立道路網路，進行路徑分析，求取時間距離，進而按時間距離進行指數衰減或直線衰減，得到定級單元因素因子影響分值。 -
It can be adapted to generate human motion traveling a straight - line path on flat ground or an irregular curved path on uneven terrain, and also adapted to different characteristic figure, ( 2 ) simulation can be easily controlled
不僅能夠用於平面直線人體運動生成，而且可以用於三維地形中復雜的不規則曲線人體運動生成，還能夠根據不同的運動人體生成個性化的真實的運動；控制容易。 -
Landing a taildragger can be difficult since the pilot must line up his approach very carefully while making constant rudder adjustments to keep the plane on a straight path until it comes to a stop
這就要求在飛機著陸觸地前，需要使用方向舵修正自己的航線，使它能夠筆直的滑翔直到安全觸地。 -
The welding path recognition system was developed with delphi 7. 0 in the environment of windows2000, which functions include filtering, sharpening, binarization and edge detecting. the straight line and curve can be identified through hough transform and line approximation method and the results are saved for nc auto programming
能夠對從ccd傳感器攝取的焊接軌跡圖像進行濾波、銳化、二值處理、邊緣檢測等圖像處理工作，並通過分別通過hough變換、直線段逼近演算法完成對直線和曲線的識別，最後保存結果為后續nc自動編程提供數據。
