深凍間 的英文怎麼說
中文拼音 [shēndòngjiān]
深凍間
英文
deep-freeze locker-
Early february 2004, the weather in washington, dc changed abruptly and became extremely cold as the northeastern section of the us suddenly entered a period called the deep freeze by local news media. at night, the temperature sometimes dropped to below zero degrees celsius 32 f, making survival difficult for those living in the streets
年2月初,美國東北部遽然進入媒體所稱的深凍期,華盛頓特區的天氣隨之轉為惡劣,變得異常酷寒,夜間的氣溫有時降到攝氏零度以下,使得露宿街頭的遊民朋友更難度日。To check the efficiency of the insulations, by varying the thickness, the width and the position of the insulations ( expandable polystyrene insulation layer ( eps ) ; polyurethane ( pu ) ) and the material of the roadbed surface in the calculation, the maximum thawed depths during the following 50 years on permafrost under the roadbed were simulated
為了檢驗保溫材料的效果,計算時採用改變保溫材料聚苯乙烯板( eps )和聚胺脂板( pu )的厚度、寬度、埋設位置及路基表面條件,來模擬路基面下多年凍土季節最大融化深度在今後50年內隨時間的變化。The indoors experimental results show the influence of soil density, moisture, permeability and restrain on the frozen - heave forces. from year ' s observation in - situ, the field data supports the relationship of foundation area, embedded depth and superimposed load with normal frozen - heave force
通過野外現場的試驗的觀測,初步掌握了基礎法向凍脹力與基礎面積、基礎埋深、附加荷載等因素之間的關系以及平板基礎所受凍脹上抬力各組成部分之間的相互影響規律。So in our experiment, we applied with freezing and drying bone and bone marrow stem cells ( bmsc ) as cellular seeds. in these conditions, freezing and drying bones provided fine interspaces structure and good adhesive and grow conditions. at the same time, bmsc which transfected vascular endothelial growth factors ( vegf ) as cellular seeds provided the seeds and stimulating factors
目前,深凍骨已商品化,免疫排斥反應罕見發生,故本實驗以凍干松質骨作為基質材料、轉染有血管內皮細胞生長因子( vegf )的骨髓基質幹細胞( bmsc )為種子細胞,這樣既保持了骨組織優良的空間結構,又提供了種子細胞和血管化的刺激因子。In this paper, the calculating model for coupling function of water movement and heat conduction in subgrade is established based on the theory of continuum mechanics and the thermodynamics. the load function ’ s influence to frost heave is qualitative consideration in the model. the relationship of moisture content and temperature change with time and depth is calculated by use of matlab
本論文基於連續介質力學和熱力學理論,建立了路基土的水分運移和熱傳導耦合模型,並定性的考慮荷載對凍脹性的影響,利用matlab數值計算軟體,求解出了路基土在凍結過程中的含水量和溫度在不同時間隨深度的變化關系。分享友人
