不能比较的

But it is a hard task to solve this equation, one reason is that the TV-norm is nondifferentiable when |▽_u|= 0, so we cant apply a linearizationtechnique such as the Newton method. The other reason is that the Euler-Lagrange equation has a highly nonlinear term. The Newton method for such equation is known to have a very small domain of convergence, and it is very difficult to make sure that the initial value such as the observed image belongs to this domain. So the Newton method is not an ideal method for solving this equation.

但是求解它比较困难，主要是因为TV-范数在|▽u|=0处不可微，不能用诸如牛顿法之类的方法将其线性化；且Euler-Lagrange方程含有一个高度非线性的项，牛顿法只有局部收敛性，对于高度非线性问题它的收敛域很小，因此难以保证所取的初始点在它的收敛域内，故一般不用牛顿法直接求解。

An ideal depolarizer can be combined with a λ/2 wave-plate and a λ/4 wave-plate rotating at different angular velocities with a certain ratio.

结果表明，让两波片以不同的角速度绕光线为轴旋转，当复合波片为一个λ/4波片和一个λ/2波片组合时，只要它们的角速度满足一定的比例时，可以组合成一个比较理想的退偏器；当复合波片为两个λ/4波片组合或为两个λ/2波片组合时，无论怎样旋转都不能组合成理想退偏器。

I'm not sure how Emilie heard about Damour. It might have been at school – where she learns, to my great regret, about events like 9/11 and the Holocaust. Or it might have been at the dinner table, where I fear I may have let my guard down the other night and vented my feelings after I read about his death.

我不能肯定Emilie在哪里听说了Damour的事情，可能是在学校，让我遗憾的是她在学校也知道了911和HOLOCaust，也或者是在吃饭的时候，我可能比较放松，宣泄了我对Damour死讯的感受。

In most species, the females are the replicators, and must be sensible about camouflage and the like, and so can't afford to be showy, but even if most of the males die because of their hampering plumage, this doesn't matter, since those left can fertilise all the females, and will probably have the best genes anyway, since they managed to survive.

在大多数物种当中，雌性是生育后代的，它们必须对于掩饰这类行为比较敏感，所以不能过于艳丽。不过即使大多数雄性因为阻碍行动的羽毛而被猎杀，这也没有关系，因为剩下的雄性会对所有雌性受精，而且由于它们设法生存了下来，它们很可能会拥有最好的基因。

Also, few centers perform pancreatectomy for nonmalignant disease because of problems with fragile diabetes, especially in alcoholics.

个人评论：单纯就其统计学意义来说，研究人员将接受手术的胰腺癌和慢性胰腺炎患者的死亡率进行了比较，统计表明手术治疗慢性胰腺炎手术死亡率低于胰腺癌患者，但这仍不能作为建议手术治疗慢性胰腺炎的依据，因为没有对慢性胰腺炎患者中手术治疗和非手术治疗患者的预后和死亡率进行对比，我们还无法认定手术治疗慢性胰腺炎效果优于非手术治疗。

Taking the Chinese films development course of time as the longitudinal axle, this essay discuss the characteristics and varieties of the photoplay view and its creation practice of Chinese Films in different age. The discussion focused on the characteristics and development countermeasure of photoplay view and its creation practice of Chinese films in new age by analyzing the classic cases. This essay used such methors like historical materials arrangement, induction and comparison during the discussion. Thus conclusions are drawn as follows: In order to guide the Chinese films towards the world, we must carry forward national films vigorously. So the traditional photoplay views, which pay attention to audiences and meeting the aesthetic habits and appreciating ways, should not be abandoned.

本文运用史料整理、归纳、比较等方法，以时间上的电影发展历程为纵轴，探讨不同时期中国电影影戏观及其创作实践的特点及变化，重点通过经典案例探讨新时期中国电影影戏观创作实践的特点与发展对策，从而得出以下结论：要让中国电影走向世界，必须弘扬民族电影，因而重视观众、适应中国观众审美习惯与欣赏方式的传统影戏观在电影实践中仍不能丢弃。

We know too little of the older law of Civil Process to be able to strike the balance of advantage and disadvantage between the different classes of remedies supplied by the Praetorian Tribunal.

我们对古代的"民事诉讼"法所知道的太少了，不能对"裁判官法院"所提供的各式救济方法之间的利弊一一加以比较。

On global optimal algorithms, a heuristic 0-1 Integer Liner Programming algorithm is achieved, which combines heuristic enumeration method and revised simplex method. Simulation experiments show that the degree and optimization efficiency in our algorithm is obviously improved compared with the MATLAB 7 bintprog function that is a 0-1 integer programming algorithm. Moreover our algorithm isn\'t relevant to the scale changes of Web services composition and candidate service sets, thus it is applicable for the scenes that the scales of Web services composition changed dynamically. But for Web services composition with service alliance, the algorithm is unable because the non-linear global optimal model of the fitness function and QoS constraints can\'t be expressed in linear mode.

在全局优化算法研究上，基于启发式0-1整线性规划算法结合了修正单纯形法和启发式枚举法，仿真实验表明该算法与MATLAB 7的0-1整数规划方法比较，在优化程度及优化效率上得到了显著改进，并且对服务组合和候选服务集合的规模变化没有明显的相关性，因而该算法可用于服务组合规模动态变化的场景，但该算法不能应用于存在服务联盟的非线性全局优化模型。

The person of this administrative levels is to just enter the recruit egg of travel child, the technology that they understand is not quite much, and train to be compared relatively at ordinary times little, not quite severe also to oneself requirement, self-ordained target, always cannot hundred finish.

这个层次的人是刚刚入行的新兵蛋子，他们了解的技术不够多，而且平时训练相对比较少，对自己的要求也不够严，自己制定的目标，总是不能百分百完成。

The static comparative advantage theory takes shape and develops in order to meet the need of western developed countries" trade practice. It can"t provide the theoretic foundation for economic development of the developing countries. Even more it might hinder the economic development of the developing countries.

静态比较优势理论是适应西方发达资本主义国家贸易实践的需要而形成和发展起来的，它在某些方面不但不能为发展中国家的经济发展提供理论依据，而且还与发展中国家的经济发展相互矛盾。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
