均勻大氣層 的英文怎麼說
中文拼音 [jūnyúndàqìcéng]
均勻大氣層
英文
uniform atmosphere-
The region of the atmosphere below 90 km has a nearly constant mean molecular mass, and is therefore called the homosphere.
90公里以下大氣區域，具有一個接近恆定的平均分子質量，因此稱為均勻層。The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film
試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。In the new dryer, the air guiding device with an orderly increased air guiding radius was introduced to improve the uniformity of airflow distributed in bed ; a three - blade device was installed to get a good pulse - fluidizing effect ; an vibrating device and a conducting device were additionally set up to make materials flow fluent and to overcome " reverse flow " respectively
它採用導流半徑依次增大的導流裝置，改善了氣流在床層內分配的均勻性；採用三葉片式脈動裝置，改善了脈動效果；增設了振動裝置，使物料輸送流暢；增設了導料裝置，從根本上解決了物料的「反流」問題。Embedded in a large - scale cold front - cyclone are often meso - and small - scale wet thermal / dynamic structures that are uneven, with a huge cold " cushion " at low levels, frequent meso cold surges and related potentially unstable zones at middle levels
在大尺度冷鋒氣旋天氣系統中，嵌有不均勻的中小尺度濕熱力動力結構。表現為低層大尺度冷墊、中空不斷出現的中尺度「冷涌」及對應的位勢不穩定區。The more is diffusion resistance, the less the oxygen quantity is. the even degree going through the diffusion layer and hydrophobic layer depends on relative change of diffusion resistance in crosswise and lengthways. if the diffusion resistance in crosswise is bigger, it will not benefit the oxygen distribution
傳輸阻力越大，通過擴散層和疏水層氧氣的傳輸量越小，擴散層和疏水層對氧氣的均勻化程度取決于其對氧氣橫向和縱向擴散阻力的相對大小變化，橫向擴散阻力大，不利於氣體的均勻化。In allusion to the characteristics of severe lithological changes, complicated mineral compositon, high carbonate content and its uneven distribution in different sections of complicated sandstone reservoirs in well xin855 of xinchang gas field, it was proposed that new acid - fracturing technique - equilibrium acid - fracturing and closed acidizing technique was used for reservoir acid reconstruction
針對新場氣田新855井復雜砂巖儲層巖性變化大，巖礦組成復雜，碳酸鹽巖含量高，且在不同井段分佈極不均勻等特點，提出採用新的酸壓技術平衡酸壓閉合酸化技術對該儲層實施酸壓改造。Atmospheric boundary - layer structure ; parameterization of land surface physical processes ; inhomogeneous underlying surface ; numerical simulation
大氣邊界層結構陸面過程參數化非均勻下墊面數值模擬According to the regional evapotranspiration analytical expression of heterogeneous soil surface applicable to moist climate region which is put forward in this paper, on one hand, soil water absorption is calculated under the consideration of the hydrological condition and hydraulic characteristic of soil surface ; on the other hand, using improved k - b model which is based on penman formula, the potential evaporation power is calculated
