In order to realize this target, the compression behavior of SC100-T6 aluminum alloy was studied under the circumatance of different deformation temperature and deformation strain ratio using the Gleeble 1500 thermal stress-strain simulator. The constitutive relationship of this kind of Al-alloy was established using the least squares fit method.

为了实现这一目的，作者应用Gleeble-1500热力学模拟试验机对不同的温度和变形速率下的铝合金SC100-T6进行等温压缩试验，得到了合金的流动应力与成形温度、应变速率的变化规律，并应用最小二乘法建立了该种合金的本构方程。

In in the country the ancient times of five the squares say, west is woman without pubic hair, the west is a 刑 day deicide, the main 萧 kills of autumn, ancient times often in the autumn go on expedition righteousness not, sentence to death a prisoner.

在中 国古代的五方说中，西方为白虎，西方是刑天杀神，主萧杀之秋，古代常在秋季征伐不义、处死犯人。

Based on these experimental spectra, desorption activation energies of benzene, thiophene, and octane on NaY were calculated by a traditional model, the least-squares method, and the first differential curve of the TPD model.

以这些TPD谱图为基础，分别采用传统TPD计算模型、最小二乘法以及一阶微分曲线法计算了苯、噻吩和正辛烷在NaY上的脱附活化能和动力学参数。

Generalized predictive control is a kind of advance control methods that is of strong robustness, can overcome the time delay of system effectively and is suitable to unstable non-minimum phase system. But it has the shortcoming of large computation load because of online solving the Diophantine equation, inverse matrix and recursion solution by Least squares. So four kinds of fast algorithms of GPC that don't need the mathematical model of plant and are highly real-time are proposed in the paper. They have laid the rationale for the application of GPC to systems that need fast response.

广义预测控制是一种鲁棒性强、能够有效地克服系统滞后、可应用于开环不稳定非最小相位系统的先进控制算法，但由于它需要Diophantine方程计算、矩阵求逆和最小二乘的递推求解，因此计算量很大，本文针对此缺陷提出四种不基于对象模型且实时性高的广义预测控制快速算法，为广义预测控制应用于实时性要求高的快速系统奠定了理论基础，具体研究工作如下。
