橫層脈 的英文怎麼說
中文拼音 [héngcéngmài]
橫層脈
英文
blanket vein-
The strong deviation and intermittence of the velocity and pressure fluctuations are found in the outer region about 3 ~ 4 times of the momentum thickness away from the mixing layer center, which are consistent with those observed experimentally
與實驗結果相符合,本文研究發現,在混合層邊緣約3 4倍動量厚度附近,流向和橫向速度以及壓力的脈動都存在強烈的偏斜和間歇現象。Results in this group there were three male and three female patients ageing 25 to 70. four were of atherosclerotic abdominal aortic aneurysms, with the age all above 60. two were suffering from dysplasia of the arterial media, with the age of 25 and 32. repeated upper gastrointestinal haemorrhage of small amounts ( herald hemorrhage ) occured before laparotomy in 4 cases, sudden unprecedented massive bleeding in 2 cases. four complained pain on the lumbus and the back. 5 suffered from infrarenal aaa, 1 from thoracicoabdominal aortic aneurysm. the fistula was located at the third portion of duodenum in 3 cases, at the upper section of jejunum in 2 cases, and at the transverse colon in one. two underwent replacement of the aorta with prosthetic graft material, who survived the surgery, bilateral axillary - femoral bypass was performed in one, and in another case the bleeding site was not detected. those 2 patients died postoperatively. the remaining two patients died of massive bleeding without exploration
結果6例病人,男女各3例,年齡25 - 70歲; 4例病理檢查為動脈粥樣硬化性腹主動脈瘤,年齡均60歲以上, 2例動脈中層發育不良,年齡為25歲和32歲; 4例術前有小量多次上消化道「信號性出血」 , 2例突發大出血,術前訴腰部背部疼痛4例; 5例為腎下型腹主動脈瘤, 1例為胸腹主動脈瘤;瘺口部位3例在十二指腸第三段, 2例空腸上段, 1例橫結腸; 4例手術, 2例行人造血管移植,均生存至今, 1例雙側腋股動脈旁路, 1例術中未找到出血部位,后2例術后死亡;另2例未來得及手術死亡。In this paper, a simplified method of calculating wind - induced response and design loads of super - high - rise buildings was proposed. coherence properties of wind load on typical tall building were analyzed and the results show that cross - wind loads at different height have strong coherence at vertex shedding frequency, and the coherence function ' s value here is near to 1
首先分析了各測點層合力的相干特性,結果顯示各測點層所受順風向風荷載之間的相干函數基本成單調衰減規律,而橫風向脈動風荷載在漩渦脫落頻率處存在和順風向不同的顯著相關性。With increasing convective mach number the streamwise fluctuation intensity varies little but the transverse and spanwise intensity along with the thickness growth rate decrease
隨著對流馬赫數的增加,流向脈動強度變化不大,橫向和展向脈動強度減小,混合層的擴張率隨之減小。分享友人
