Per usual, Sea Ray makes you stand on a little platform about 3 above the bilge, over which oily bilge water sloshes, making it hard to stand up on an oily deck, plus you get to track oil all over your nice salon carpet, which had already happened.

每如常，海光让你的立场有点平台，约3 以上的舱底，其中含油舱底水sloshes ，很难站起来，就一含油甲板上，再加上你来追踪所有的石油超过您的尼斯沙龙地毯，已发生的事情。

A comprehensive research has made in the application of elliptic curve based bilinear mapping in the group signature, security of bilinear mapping is established on the GAP group. Because the DDH problem is easy to solve in GAP, this fact results it is very difficult to design a bilinear mapping based group signature scheme which can satisfy anonymity and the tractability.

对基于椭圆曲线的双线性映射在群签名中的应用进行了深入的研究，由于双线性映射的安全性建立在GAP群上，而在GAP群上的DDH问题是容易求解的，这样导致在基于双线性映射的群签名方案设计中很难同时兼顾群签名的匿名性和可跟踪性。

It is related to the variational inequality problem, bilinear programming, nonlinear equation. So there is actual meaning and theories value to study how to solve it.In recent years, many algorithms for solving the generalized linear complementarity problem are put forward. But they basically belong to the traditional iterative methods, and may not be efficient since the computing time required for a solution is greatly dependent on the dimension, structure of the problem and the complexity of the algorithm used. Different from the traditional algorithms, the neural network has many advantages on calculations and real-time applications for its inherent massive parallelism and electric circuit implementation.

近年来，人们对广义线性互补问题提出了许多算法，但这些方法基本上属于传统的迭代法，由于它们的计算时间极大地依赖于问题的规模、维数以及所使用的算法，因此很难满足实时并行的要求，与传统数值方法不同，由于内在的并行分布处理信息的特点及电路实现的潜能，神经网络有着许多计算上的优势和实时性的应用，自Hopfield提出著名的人工神经网络模型-Hopfield神经网络，并将其成功应用于优化问题后，用神经网络求解优化问题得到了相当深入的研究，并取得了许多重要的成果。

You would not think it to look at him, but he is bilious - mr. cole is very bilious.

关于这一点，你从他的外表上看是很难发现的。

Ball and Rose Routine: A white rose is plucked from it抯 stem and turns into a white billiard ball, which vanishes and is reproduced as a silk scarf is waved in front of it. There are several more vanishes and reappearances, then the ball changes color. The new red ball now becomes white then red and continues to change several more times.

如果你还没有遇到过有人能控制你的心灵时候，你将会觉得这是不可思议的，现在Derren Brown将会现你证明这个超能力，控制你的想法，这里，他将会在第四频道的一个小节目中证明如何让你压抑住的兴趣表现出来，你放心，这不纯在手法上的问题，因为那是很难在那么多的观中注视中不出现麻烦的。

However, the computer's own binary based language, or machine language, is difficult for humans to use.

然而， 人们是很难直接去使用计算机的二进位语言和机器语言的。

Binge eating is hard to diagnose because it can take so many forms.

狂欢的饮食是很难诊断，因为它可以采取许多形式。

With the increase in pesticide wastewater of compounds that are difficult to biodegrade, conventional biochemical treatment methods cannot completely remove contaminants from wastewater.

随着农药废水中难生物降解化合物的增加，常规的生化处理方法无法完全去除水中的污染物。
