中文拼音 [shùnshíbǐrè]
瞬時比熱
英文
instantaneous specific heat-
Principal conclusions were drawn as the following : the non compatibility of pressure or velocity of the gas on both sides of the contact surface is the cause of the formation of shock wave ; the heating effect of reflective shock wave to driving gas during charging or exhausting process is the internal mechanism of peak oscillating effect, and all the factors that influence the formation and the running of the shock wave will influence the peak oscillating frequency, cooling effect
主要結論如下：熱分離機內激波形成的原因是射氣瞬間接觸面兩側壓力和速度不相容；峰值振蕩效應的內在機制為反射激波對充氣階段的驅動氣或低溫排氣的加熱，凡是影響激波形成及運動的因素都將對峰值振蕩頻率、冷效應及熱效應產生影響；當充、排氣時間比為0 . 1763時，最佳射流激勵頻率出現在高階峰值振蕩頻率上。In short, through retrieving the parameter such as surface albedo, surface temperature and surface emissivity, all the energy flux such as net radiance flux, soil heat flux and latent heat flux can be computed in sequence further, then latent heat flux which provide energy for et can be computed based on energy balance equation, finally instantaneous et and daily et can be obtained
總之，根據地表能量平衡方程，通過計算對地表反照率、地表溫度、地表比輻射系數、歸一化植被指數等參數進行反演，進一步計算出了地表凈輻射通量，土壤熱通量和潛熱通量，最後獲得了遙感影像成像時的瞬時蒸散及當天的總蒸散量。Through experimentation, we compare the heat performance of hhchp with that of a solar water heater of glass vacuum tube ( abbreviated as hgvt ). the heat performance of a solar water heater includes instantaneous efficiency, average heat efficiency and heat loss coefficient
通過大量的實驗，對蜂窩熱管平板式太陽能熱水器和全玻璃真空管式太陽能熱水器的熱性能進行比較，包括瞬時效率、日平均效率、熱損系數等。In contrast with conventional thermo - ionic cathode, field emitter array ( fea ) cathode has many special advantages, such as room - temperature operation without a cathode heater, high current density, low power dissipation, excellent on / off isolation characteristics and instant turn - on characteristics
與傳統的熱陰極相比，場發射陣列陰極具有許多獨特的優點，如無需加熱，可以在室溫下工作;電流密度比熱陰極高幾個數量級，並可工作在低電壓調制下;功耗低;極好的開關特性;可瞬時啟動等。In order to make clear the influence of two kinds of stress to the total stress, equivalellt thermal stress of lpg vessel under only tempertae load and its equlvalent mechanical stress under only inner wall stress are calculated and analyzed, then its equivalent total stress is calculated, analyzed and compared
為了弄清這兩種應力分別對總壓力的影響的大小，首先單獨對液化氣壓力容器僅受溫度載荷時的瞬態當量熱應力以及僅受內壁壓力時的瞬態當量機械應力進行了計算分析，然後計算了液化氣容器的當量總應力並對其進行了分析比較。In the study of the flash temperature, the formula is given for the flash temperature by the heat exchange theory. the effects of geometric and operating parameters on the flash temperature are studied
在面齒輪傳動齒面瞬時溫升的研究中，利用傳熱學基本原理，推導了齒面瞬時溫升的基本公式，求解了各有關計算參數，研究了模數、壓力角、傳動比等參數變化時對齒面瞬時溫升的影響。Compared to heat transfer in the external region of borehole, mass and heat capacity of materials inside the borehole are insignificant and negligible. thus, heat transfer inside the borehole is approximated as steady - state heat transfer except for analyses of short times ( a few hours )
與鉆孔周圍區域傳熱過程相比，由於鉆孔內材料的熱容量較小，因此除了討論短時間（數小時）的瞬變傳熱問題以外，可以忽略鉆孔內材料的熱容量，把該部分的傳熱近似作為穩態傳熱處理。分享友人
