當你寫的能工作的代碼和你打字速度一樣快,而且失策率為零,這通常意味著你正在精通這門語言。The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller. the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution. for highly skewed propeller, the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface, which result easily in incorrect calculation results of velovity on blade surface, even in iteration divergence and calculation failure. a “ non - conventional grid ” is developed to acoid these problems. this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller. the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure. by sample calculating, the obtained results are satisfied the experimental data
採用面元法預報大側斜螺旋槳水動力性能,螺旋槳表面及尾渦面離散為四邊形雙曲面元,每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言,槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元,這容易使槳葉表面速度的計算結果不正確,甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法,能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件At that time, the entry of the u. s. into the global economy badly disrupted the economies of western europe as the u. s. was rising and britain was slowly loosing its superpower status
在那時,全球經濟受西歐經濟影響,非常低迷,而美國經濟則上升訊速,英國正逐漸失去世界超級大國的地位。However, a positive osteogenic effect depends on sufficient stimulation provided in terms of the intensity of the exercise workload, duration of the exercise, frequency of training, length of the training period, and site affected by the physical activity
大體上,阻力運動訓練、承重型的耐力訓練、甚至於日常步行訓練均有助於減緩骨質流失的速度,然而欲得到足夠的骨骼刺激效果仍需視所採用的運動型態與運動量而定,而且養成長期持續運動的習慣才能確保正面效果的維持。Fried man p , stevenson w g , bittl j , et al. left main coronaryartery occlusion during radiofrequency catheter ablation of idio2athic outflow treat ventrcular tachycardia j. p a ce , 1997 , 20 : 1 184
馬堅,王方正,余培禎,等.射頻消融治療起源於左室流出道的非持續性室性心動過速和頻發性室性早搏j .中華心律失常學雜志, 1999 , 3 ( 2 ) 126 - 1296In recent years, the screw pump gets more and more extensive application with its unique performance in the oil field, in order to improve the output of crude oil, we should select pump of big displacement or increase the rotational speed, but this will make the ground system vibrate seriously, causing the system to be unable to work normally or some spare parts lose efficiency too early
近年來,在油田現場螺桿泵以其獨特的性能得到越來越廣泛的應用,為了提高原油產量,當選用大排量螺桿泵或增加螺桿泵的轉速時,地面驅動系統將產生強烈的振動,導致系統無法正常工作或系統內的某些零部件過早失效。Flow meters may be affected, giving incorrect reading. the rate of corrosion of pipeline may also increase. the abnormal current induced in power grids may damage transformers because of overheating
