查询词典 gravitational attraction

As a result, for feed-forward NN model this paper first proposes the concepts of"attractor"and"attraction region","fake attractor"and"fake attraction region", and norm of describing"attraction region". Further this paper presents a mathematics method of calculating feed-forward NN"attraction region", it solves the overelaborate job of checking NN fault-tolerance performance by testing all detecting samples, so to test fault-tolerance performance using theoretic characteristic norm is an important break. In accordance with feed-forward NN low fault-tolerance and difficult to satisfy practical application, according to practical application theory, this paper presents an actual method of enhancing NN fault-tolerance performance, builds the mechanism of reconstructing NN model based on combining NN and fuzzy process, reforms NN "fake attractor"and"fake attraction region"to enhance NN fault-tolerance performance greatly.

为此，本文首先给出了前馈NN模型的&吸引子&和&吸引域&，&伪吸引子&和&伪吸引域&的定义，以及描述吸引域的指标，在此基础上提出了一种计算前馈NN模型&吸引域&大小的数学计算方法，该方法提出解决了目前依靠对检测样本的测试工作来检验NN容错性的繁琐工作，而用具理论意义的性能指标来检验，这是一个重要的突破；针对前馈NN容错性较低以致难于满足实用的缺点，根据NN实用稳定性理论，提出了一种提高其容错性的实用方法，建立了基于NN与模糊处理相结合的NN模型重构机制，重构NN&伪吸引子&和&伪吸引域&来大大地提高NN的容错性。

The gravitational fields required to make such a closed time-like curve would have to be very strong,"on the order of what you might find close to a black hole," Ori told LiveScience."We don't have any way of creating such strong gravitational fields today, and we certainly have no way of manipulating any such gravitational fields."

要制造出这样一条封闭时间曲线的引力场非得要非常强，"大约和你在一个黑洞附近找到的那么大"Ori告诉LiveScience"我们现在没有任何办法来制造这么强大的引力场，而且，可以肯定地说，我们无法来控制任何一个这样的引力场"

Therefore has carried on the next experiment: For the proof slip of paper dry scope migration is but because of receives the earth's attraction the influence to concentrate toward the slip of paper lower part, we have carried on the next experiment, we cut the slip of paper the long strip, then changes the level laying aside, because whether there is can't such slip of paper both sides underneath the space cause the hydro energy downward to concentrate create the experimental result the difference, after the experiment discovered, after has removed this difference, the slip of paper both sides dry need the time is nearly same, but according to above experiment, we arrived following conclusion, the slip of paper dry scope is downward moved from on downward migration because of the slip of paper in moisture content by the attraction attraction, causes under the slip of paperAbove the hydraulic modulus also must be many, above the natural slip of paper falls very quickly on the few water on the evaporation, but under many moisture content need more time can evaporate, causes the slip of paper dry scope most above downward to increase slowly from the slip of paper.

急！！！物理翻译中翻英请帮帮忙於是进行了下一个实验：为了证明纸片〈paper sheet〉乾燥范围的移动〈boundary of drying〉是因为受到地心引力的影响而往纸片下部集中，我们又进行了下一个实验，我们把纸片剪成长条状，然后改为水平放置，这样纸片两端就不会因下方有无空间使水能往下集中而造成实验结果的差异，实验后发现，去除了这个差异后，纸片两端乾燥所需的时间几乎相同，根据以上的实验，我们的到了以下的结论，纸片乾燥范围从上往下移动是因为纸片中的水分被引力吸引而往下移动，使得纸片下面的水比上面还要多，自然纸片上面就少量的水很快就蒸发掉，而下面较多的水分需要更多的时间才能蒸发完，使得纸片乾燥的范围从纸片最上面慢慢往下增加。
