  1. At last, there is a practical design of gshp - radiant system in a villa in chongqing. the compare of the gas - heater radiant floor system and the gshp radiant floor system indicates that the heating performance coefficient of the gshp is higher than the gas - heater to a large extent. in addition, this united system can use the closed circling water in the underground heat exchanger to remove the surplus heat load in transitional season

    通過燃氣熱水器制熱的輻射地板供暖與地源熱泵制熱的輻射地板供暖性能實驗的對比，可以看出地源熱泵的供熱性能系數高於燃氣熱水器，同時在長江中下游地區還可在過渡季節利用閉式循環水吸收土壤冷量對房間進行供冷，提高系統運行的經濟性。
  2. Present the experimental research carried out on strain and stress by applying the resistance strain surveying technique to the big hole sealed heads in the new fire - tube heating boilers with the laws of strain and stress distribution obtained and allowable working pressure given because there is no applicable standards or specification for calculating the strength of crude oil heating boiler heads perforated by densely distributed big - holes, which, to a certain extent, hampered the further development of crude oil heating boilers in china, and concludes from experimental results that strain and the stress of circumference are fairly large near the edge of big - hole, and the cross ribs enhance strength of sealed head to a certain degree

    油田火筒加熱爐密集大開孔封頭的設計計算，因沒有相應的強度計算標準在一定程度上限制了我國油田火筒加熱爐技術的發展.採用電阻應變測量技術，對新型火筒加熱爐大開孔封頭進行了應力應變試驗研究，得到了封頭的應變和應力分佈規律，給出了大開孔封頭允許的工作壓力.試驗結果表明，大孔邊緣圓周處應力應變較大，十字筋板對封頭有一定加強作用
