    場景成像的合成孔徑雷達一般是正側視放置，但是載機不可避免的要受到各種擾動影響，雷達會有一定的斜視角，從而導致了多普勒中心頻率不為零，多普勒調頻斜率也隨著雷達斜視角改變。
  5. Nozzle in the furnace the gas - quenching pressure can be 15 bar, airflow is big and uniform, cooling rate is very high

    配置內置高效熱交換器，以及經優化設計的氣淬系統，冷卻氣體流量均勻且流速大，冷卻速度高
  6. Two typical examples analyses are conducted for the average conditions both of winter and summer climates under vapor diffusion and air leakage. a further discussion is set forth to determine the main factors that the moisture accumulation in wall is affected. it is found that the factors are the relative humidity at the wall surface, indoor temperature, permeability, air pressure difference and rate of the infiltrative or exfiltrative airflow

    本文首先研究了墻體內的濕氣遷移過程，詳細分析了濕積累現象形成的原因，通過對夏、冬兩季平均氣候下墻內溫度、水蒸氣壓力、相對濕度及濕積累在僅有擴散、擴散與空氣滲透同時存在等情況所作的具體計算，發現墻內、外表面的相對濕度、室內溫度、滲透率、空氣壓差以及空氣的滲流速度是影響墻內濕積累的主要因素。
  7. To collocate passage of leading airflow, force gas - cooling, so the current is strong and uniform, cooling rate is very high
