地温度 meaning in English

geothermometer

The main results , obtained in this dissertation , may be summarized as follows : 1 . the identification problem of thermal parameters in the paleotempture field equation is reported
本文取得的主要结果可概括如下1 、研究古地温度场方程中的一些性能参数的识别问题。
On some reasonable assumptions , the existence and the uniqueness of the solution of partial differential equation are proved by using the semigroup theory ; then based on the current basin temperature from the practical survey , the mathematical model about the identification problem is established , and the identifiability and the existence of the optimal solution of the identification problem are proved ; in terms of the adjoint method presented by chavent , the optimality condition of the identification problem is given ; finally the corresponding algorithm is devised
在适当的假设条件下，利用算子半群方法证明古地温度场方程解的存在惟一性；根据现今实测温度，建立了问题的参数识别模型；证明了可识别性、最优解的存在性；利用chavent等人提出的伴随方法，给出参数识别问题最优解存在的最优性条件和求该参数识别问题的算法。
