不能克服

This research method is independent of Green"s function and variational structure. So it can tackle with the BVP for non self-adjoint and self-adjoint difference equations and overcome the difficulties brought about by the establishment of Green"s function, a study of the sign and the estimate of below and above bounded for Greens function.

It's pointed out that soft sensor will play more important role in field bus network control system. According to this, a crude solution was addressed. At last, we point out that soft sensor technology must used to build an information warehouse for the whole enterprise, combined with data fusion, data warehouse, data rectification and other related technologies. The main contributions of this dissertation are as follows: The background, requirement, and application situation of soft sensors are expounded, the theories, methods and skills of soft sensing technology are analyzed, and the fruits and problems in current soft sensor technologies are summarized. Some new methods of soft sensor is proposed: A principal component analysis-based secondary variable selection method are proposed; A new conception which modeling data should have gross error detection is addressed, and then a cluster analysis-based modeling data gross error detection method is given.

本文的主要贡献有：对软测量技术根据实践的要求进行了一定的理论研究，针对具体问题提出了新的方法：讨论了辅助变量选择问题，研究了基于主元分析的辅助变量选择方法，该方法克服了传统方法只能利用数学模型产生的仿真数据进行最优辅助变量选择的缺点，可以根据历史数据进行辅助变量选择；提出了建模数据显著误差侦破的概念，指出传统的显著误差侦破研究的是已知过程数学模型的情况，而建模时数学模型是未知的，但是直接来自现场的数据并不能保证不含显著误差，并用基于聚类分析的方法解决了该问题，该方法利用聚类分析原理，直接面对过程数据，不需以过程模型为基础，在此基础上给出了软测量建模过程中样本数据的处理方法。

Three kinds of arm's robust control theorys are designed: the torque control based on FNN controller, the computed torque control with sliding mode compensation and the computed torque control with WNN compensation. FNN syncretizes the reasoning ability of fuzzy control and parameters' self-learning ability of neural networks. It does not depend on the precision of the mathematical model, and can overcome the impact of the uncertainty effectively. So FNN is regarded as the manipulator controller and used to the trajectory tracking of arm control. The computed torque control with sliding mode compensation is designed.

在此基础上，研究了机械手臂的鲁棒控制法，分别设计了基于模糊神经网络的机械手臂力矩控制方法、基于滑模变结构控制补偿的机械手臂力矩控制方法以及基于小波神经网络补偿的机械手臂力矩控制方法，具体内容如下：模糊神经网络融合了模糊控制的推理能力和神经网络的参数自学习能力，它不依赖于对象精确的数学模型，能有效地克服被控对象存在的不确定部分的影响，本文把模糊神经网络作为机械手臂的关节伺服控制器，通过对网络参数的学习训练来调整机械手臂关节的控制力矩，实现对机械手臂的轨迹跟踪控制。

I am excited to prove those who have already written us off that theyare wrongs The challenge ahead is great no doubt about that but the potential of tough people should never be overlookeds We have ateam ofplayers that have continually been cast off as too small too slow andnot good enoughs Instead of believing those things people say about useach of us in our own way have worked harder to overcome the odds and the doubts of otherss We are in the NBA to an extent because we aretough individuals and don't let the outside expectations stop us fromexcellences For us it's just another year to prove people wrong.

问，面临的挑战异常艰巨，但是请不要小看勇者的潜力。我们这一帮球员一直被人说成是块头太小，速度太慢，不够优秀。我们一点也不认同这些话，相反，我们中的每个人都在努力工作，希望能够克服困难，回击人们的质疑。我们之所以能在NBA这样级别的联盟中打球，就是因为我们每个人都很勤奋，不会让外界的质疑妨碍我们变得更好。对我们来说，这只是一个需要再次证明别人看走眼的赛季。

With this method, the nextto-leading order Debye screening mass was evaluated within real time hot QCD. Since the gluon damping rate was included self-consistently on the internal line of the self-energy, the infrared divergences were removed without putting by hand in a nonperturbative magnetic mass as a cutoff, and the results are positive and gauge-independent. In addition, the selfconsistent calculation method of the damping rates of the fast moving particles in a QGP was suggested, the self-consitent equations were derived at finite tempeature without infrared divergences, and the approximation solutions were shown. Meanwhile the relaxation times of the gluons and quarks were estimated as τ〓～0.7fm/c and τ〓～1.5fm/c at energy scales of RHIC and LHC.
