Conducts tests of them both in Chongqing and Shanghai. Finds out that the results from the calculation and analysis by means of the mathematical model on short term function of the vertical placed rock heat exchangers are in accordance to those from the test, and on long term continual function the results are lower than the measured ones. Researches show that the rock pattern and the primitive rock temperature determined... 【基金】 国家自然科学基金资助 ( 5 97780 0 7)
