According to people who had moustaches, inhaling the air component quantitative analysis and found that the air sucked into the presence of dozens of hazardous substances, including phenol, toluene, acetone, isoamyl asked diene, and other carcinogens,, Who had moustaches, who inhaled the air pollution index, is 4.2 times that of ordinary air.

据对留有胡子的人吸入的空气成分进行定量分析，发现吸进的空气中含有几十种有害物质，其中包括酚、甲苯、丙酮、异戊问二烯等多种致癌物，留有胡子的人吸入的空气污染指数，是普通空气的4.2倍。

Alas, I sold my entire GEICO position in 1952 for $15,259, primarily to switch into Western Insurance Securities. This act of infidelity can partially be excused by the fact that Western was selling for slightly more than one times its current earnings, a p/e ratio that for some reason caught my eye. But in the next 20 years, the GEICO stock I sold grew in value to about $1.3 million, which taught me a lesson about the inadvisability of selling a stake in an identifiably-wonderful company.

可惜的是，在1952年我以15，259美元的价钱将全部的GEICO股份出清，然后将所得资金投入到西方保险证券公司之上，这项变心的举动，一部份的原因是因为西方保险证券当时的股价相当吸引人，本益比只有一倍左右，然而在往后的二十年间，当时被我卖的的GEICO股份的价值却成长到1，300万美元，这样的结局让我体会到绝对不能卖掉一家明显的好公司的原则。

Heaven pity him when the guilty creature has deceived him and comes with her tears and lamentations to throw herself at his feet in self-abandonment and remorse, torturing him with the sight of her agony, rending his heart with her sobs, lacerating his breast with her groans. Multiplying her own sufferings into a great anguish for him to bear, multiplying them by twenty-fold, multiplying them in a ratio of a brave man's capacity for endurance.

老天同情他，当那罪人欺骗了他，又带着泪水和哭泣，自暴自弃地悔恨交加地投身在他的脚下，以她的痛苦的景象折磨他，以她的鸣咽撕裂他的心，以她的呻吟割切他的胸膛；把她自己的苦处转化成为让他去忍受的极大痛苦，使痛苦二十倍地增长，依照勇敢男子汉的忍受力按比例地增长。

With the guide of non-linear program theory, by using interpolative steps and inexact line search, an improved conjugate gradient method was found, by which the training rate of BP networks increases by tens or hundreds of times. Moreover, the improved method is effective to solve non-linear equations for which Newton's method does not converge owing to the problems of the quadratic derivative and inverse matrix.

通过大量的数值模拟试验发现，在非线性规划理论的指导下采用间插步骤和不精确的一维搜索技术改进的共轭梯度法，是基于梯度和共轭方向的连续搜索算法中最有效的算法，这种算法使BP网络的训练速度提高几十到几百倍，使BP网络的实际应用效果大为改善；而且这种算法对于用牛顿法由于求二阶导数和求逆矩阵等问题难于收敛的非线性方程组的求解也是很有效的。

For the past twenty years, the Chinese economy has achieved a growth rate averaging nearly 10 percent per year, resulting in a quintupling of output per person.

过去的二十年里面，中国的经济以每年接近10%的平均速度增长，造成了每个人的生产量翻了5倍。

Given the record of the last two decades, it becomes increasingly hard to see how sub-Saharan Africa, for example, will experience a projected quintupling of human numbers within another century as long as gross environmental impoverishment continues to spread.

给最后二十年的记录，只要总共的环境贫穷继续传布，它变成逐渐困难见到次撒哈拉的非洲如何，举例来说，在另外的世纪内将会经历被计画的人类数字的使成五倍。

A group of scientists at Carnegie Mellon University in Pittsburgh, Pennsylvania, studied insects like water striders and then built a small robot using ultra-lightweight carbon fiber that is also able to walk on water. But they still have some improvements to make — they said the water strider is able to move about 20 times as fast.

宾州匹兹堡的卡内基美隆大学有一群科学家在研究水黾等昆虫的构造后，利用超轻的碳纤维制作了一个也能在水上行走的小型机器人，但他们仍有一些尚待改进的部分──他们表示，水黾在水面上移动的速度比这机器人快上约二十倍。

Those inclined to think of the 20th century as the era of the common man can cite the inventor of one of the century's greatest machines as a case in point.

对于那些倾向于把二十世纪看作是一个庸辈倍出时代的人来说，有必要让他们知道这个世纪中有一个最为伟大的机器发明人。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
