将新近发展的双倒易边界元法（DRBEM）推广到求解生物传热热波模型（TWMBT）中，建立了一种实用算法。作为该方法的一个数值例子，对二维区域在一定边界条件和微波加热条件下的温度场进行了初步模拟，得出了一些有意义的结论。通过与有限差分法（FDM）一维计算结果的比较，验证了DRBEM的有效性。由于DRBEM不受生物体复杂形状的限制，不需要对内部区域进行离散化，节省大量的CPU时间，易于处理不同的生物热模型等独特的优点，DRBEM有可能成为预测和控制生物体在高温或低温下瞬态温度场的一种重要方法。
The newly developed dual reciprocity boundary element method (DRBEM) was extended to solve the thermal wave model of bioheat transfer (TWMBT) and a practical algorithm was established. A preliminary simulation of the temperature evolution in a two dimensional zone under certain boundary conditions and micro wave heating was conducted as a numerical illustration for the method and some meaningful conclusions were drawn. The validity of DRBEM was testified through a comparison with finite difference method (FDM) under one-dimensional calculation. Owing to its unique advantages like not confined by the complex shape of biological bodies, no need of discretization of the inner domain, save vast CPU time and easy to deal with different bioheat models, DRBEM may become an important approach for predicting and controlling the transient temperature field of biological bodies under hyperthermia or hypothermia.
