The objective of this study is aimed at the implementation of parallelized numerical quadrature routines. The algorithm we choose for numerical quadrature routines is the so called "Adaptive Romberg Tree integration scheme"(abbr."ARTint") proposed by Lin et. al.[1997]. This numerical quadrature scheme can arrange the function evaluation points adaptively in accordance with characteristic of the trend of variation in integrand function values. When the accuracy of the numerical quadrature value is requested to be increased, a newer and larger set of function evaluation points must be incurred. The main advantage of ARTint method is the inclusion of all function evaluation points used in previous stages. It is this feature of ARTint method that makes it a quadratue scheme with prominent computation efficiency.

本研究在探讨数值积分程式之平行化，所使用的演算法为林聪悟与林佳慧[1997]一书所提出的「Romberg树自动布点数值积分」架构，此一数值积分方法能以适应被积函数值变化情形方式自动安排积分点来进行数值求积计算，在提高阶数以获得更高精度积分值的过程中，此一方法只须再计算新增加积分点的函数值，搭配先前已计算过的函数值的重覆运用即可获得更精确的数值积分估计值，如此将能减少升阶过程中函数求值计算的次数，有效率地完成单重积分的数值计算。

Moreover,the NRTL and UNIQUAC models,of which theinteraction parameters were expressed as afunction of the temperature from 298.2Kto 348.2K,were respectively used to correlate the LLE data in the range of 298.2K to348.2K for each binary system.The results show that the correlation accuracy of theUNIQUAC model is better than that of the NRTL model and is satisfactory.

为了便于应用，将NRTL模型和UNIQUAC模型中的参数表达成温度的一次函数对每个系统在不同温度下的互溶度数据同时进行了关联，结果发现三个系统的UNIQUAC模型的目标函数值均要小于NRTL模型的目标函数值，且UNIQUAC模型计算互溶度与实验值的偏差小于NRTL模型的计算偏差，UNIQUAC模型的关联精度是令人满意的。
