难以克服

Neural networks is viewed as a universal approximator for nonlinear functions, but there are some fatal bugs with it, so it is necessary to find another method more right for neutralization process.

神经网络是目前中和过程非线性系统建模中常用的一种建模方法，但本身具有一些难以克服的缺陷降低了它的发展和应用效果，因此寻求更适于中和过程非线性系统建立模型的理论及方法是十分必要的。

Have been developed. However, these approaches are all complicated in the description of physical mechanism and expensive in the consumption of computational resource, even encounter the convergence problem of the computer algorithm when the size parameter, the asphericity, or the refractive index of the scattering particle becoming too extreme.

然而，这些方法在物理机制的描述上过于复杂，并且要求占用极大的计算资源，甚至会出现难以克服的收敛性问题（当一些关键参量如粒子的尺度，非球性，折射率变得极端时）。

The crude assignation of territory, after just a few weeks of study by British officials, may also have been too great a handicap to overcome.

粗枝大叶的领土划分——英国当局经过短短几周的考察后划分的——可能也是一个难以克服的巨大障碍。

Through discussing good and bad points of several common statistical measures and examining the relationship between such measures,we discover that the statistical method itself also has some unsatisfactory places,one of improvement means is to use the axiomatic method and the welfare method.

从理论上讲，有许多种可实际应用的度量不平等的方法，每一种度量方法都具有一些值得称颂的优点，同时也存在一些难以克服的缺点，其中实践中使用得最为广泛的就是统计度量方法。

However, the high cost of the catalyst and the metal contamination of the product remain to be surmounted.

但是，金属催化剂的昂贵价格和重金属的污染一直是工业应用的难以克服的障碍。

Nevertheless, this method generally have the following defects, with poor accuracy in calculating (1) bubble point density;(2) high density liquid region; and (3) critical region etc.

这种方法虽然简单，但有着难以克服的缺陷，不能解决：（1）泡点密度的计算问题（2）高密度液相区的计算（3）临界区的计算等。

Demosthenes, who was faced with such a formidable problem as stuttering, could do it, I can do it, too.

But rather than going on to enjoy the public affection for his act of heroism, he was consumed by the demons of combat stress he could not exorcise.

但他却无法享受公众因为他英勇行为的爱戴，反而陷入了他难以克服的作战压力梦魇里。

In this dissertation, we have arranged the contents as"from overall to partition, and then from partition to overall". First, we systematically study four parts: detection information fusion, state information fusion, attribute information fusion and decision information fusion, then from higher point of view we integrate the four parts. Furthermore, on the basis of the theoretical studies, some effective approaches to the engineering practical problems, which are difficultly solved by the traditional approaches, are provided.

本文针对此问题按着"从整体到局部，由局部再到整体"的研究思想，首先系统地从检测信息融合、状态信息融合、特征信息融合和决策信息融合四个方面进行了研究，然后从更高的角度将上述四个部分进行融合，并为解决某些传统理论难以克服的工程问题提供了新的有效方法。

This word enough shows the hard pitch that makes a female lawyer, it makes a lot of people shrink back from difficulties, have a few women however however, the actual strength that depends on oneself and tough, overcame the difficulty that the ordinary person overcomes hard, be in persistently the lawyer steps down on this road.
