不能比较的

Studies have shown: Boy students think of knowledge counted to use early than girl student, make investigation or do experiment whether boy student think fast, touch it than girl student early; The man girl students query ability is not strong , but the thinking of the boy student is relatively more broad , the ability to pinpoint the problems is better than girl student a little ; In making decision, boy students can see essential meaning through the phenomenon a bit so, girl students seem narrow thinking , will usually confine to judging the case as it stands.

研究表明：对于从统计的角度思考与数据信息有关的问题时，男生要比女生更早想到运用统计的知识解决问题，无论是做调查还是做实验都是男生比女生想得快、动手早；在面对各种资料时，男女生的质疑能力虽然都不强，但还是男生的思维相对比较宽广，思考问题时，相对全面，发现问题的能力明显比女生强一些；在做决策方面，男生有那么一点能透过现象看到本质的意思，总是希望找到解决问题的方法，女生则显得思维面窄，通常会局限于就事论事。

The influences of the shock thickness and Alfven waves on the particle acceleration by diffusive shock waves are numerically studied through solving one-dimensional diffusive equation including the second-order Fermi effect. It is shown that the spectral index of the energetic particles strongly depends on the shock thickness. For example, the spectral index increases from 2.1 to 3.7 in the low energy range of 3-10 MeV and from 2.5 to 5.0 in the high energy range of 20-60 MeV as the thickness increases. The spectral index decreases from 4.3 to 3.1 as the particle injection energy increases. The spectral index decreases from 4.0 to 1.8 at the quasi-steady stage with the enhancement of the compression ratio from 2 to 4. The results indicate that under the influence of Alfven waves, the energetic particle spectrum at lower energy becomes flat and the spectral index decreases from 2.5 to 0.6 in the low energy range of 3-10 MeV and from 11.6 to 5.0 in the high energy range of 20-60 MeV. At the same time, the rollover energy reaches 19.6 MeV. The spectral index decreases from 5.8 to 2.9 as the energy density of Alfven waves increase. All these results are basically consistent with the theoretical models, as well as the observations of typical energetic particle events.

通过数值求解包含二阶费米加速的一维扩散方程，探讨在准平行激波条件下激波厚度和级联阿尔芬波对粒子加速的影响，研究粒子分布函数的演化与激波厚度和阿尔芬波强度的内禀关系，计算结果表明：(1)考虑激波厚度时，谱指数明显依赖于激波厚度，随着厚度从0.32增大到2.56，低能端(3-10MeV)谱指数逐渐从2.1增加到3.7，高能端(20-60MeV)谱指数从2.4增大到5.0，能谱逐渐变软；当初始注入粒子动量增大1.3倍，质子能谱指数从4.3减小到3.1，且与零厚度激波加速的谱指数差值缩小；厚度不变时，随着压缩比从2增加到4，准稳态分布时低能端(3-10MeV)粒子能谱指数逐渐从4.0减小到1.8谱变硬；(2)在级联阿尔芬波的影响下，随着时间的增大，粒子在低能处(3-10MeV)的谱指数从2.5减小到0.6高能端(20-60MeV)谱指数从11.6减小到5.0，能谱变硬，拐点能量值从7.5MeV增大到为19.6MeV；随着波的能量密度增大，谱指数从5.8减小到2.9，这表明阿尔芬波强度越大，加速效率越高，通过与激波厚度解析结果和高能粒子事件的观测能谱比较发现两者是一致的，说明数值模拟结果是可靠的。

The steam-engine has relieved them of much exhausting and degrading toil; wages have risen; education has been improved and become more general; the railway and the printing-press have enabled members of the same trade in different parts of the country to communicate easily with one another, and to undertake and carry out broad and far-seeing lines of policy; while the growing demand for intelligent work has caused the artisan classes to increase so rapidly that they now outnumber those whose labour is entirely unskilled.

蒸汽机减轻了他们许多费力和有害身体的工作；工资提高了；教育已经改良而且已经比较普及；铁道和印刷机使国内各地同一行业的人能易于联系，并且使他们能够从事和实行远大的政策方针；同时，对智力工作的日益增长的需要，使技术工人迅速增加，现在他们的人数已超过了那些完全不熟练的工人了。

Fortunately for liars, as many as 99% of people will fail to spot these fleeting signals of inner torment (of the 15,000 whom Ekman has tested, only 50 people have been able to without training. He calls them "naturals").

对撒谎的人来说比较幸运的是，99%的人都看不到这些表达内心痛苦的转瞬即逝的信号（埃克曼测试了15000人，只有50人能在未培训的情况下看出来，他把这些人称为&天才&）。

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

作为一种行星表面使用的飞行器，女妖战机不需要一台能逃脱星球的引擎并在轨道上战斗，取而代之的是一种技术人员认为比较合适的双涡轮风扇发动机。

First, we introduce the linearly distributed stress tensors as the source and by means of two-dimensional finite-difference scheme to obtain the response of this source, then the point source response is generated by correcting both the wave forms and geometrical spreadings for the linear respons.

但在理论地震学，工程地震学和勘探地震学中横向不均匀介质中的波传播问题非常重要，此时使用有限差分法和有限元法等离散数值方法比较有效。鉴于目前计算工具的限制，三维模型的有限差分计算虽然在理论上是可行的，但很少能用于实际。

I plan to buy a car this year, a friend asked about the online search has now basically have several vehicles in the area to be elected, I am ready to re-store sales of motor vehicles to see, but I listen to said a shop on the sale of a brand of cars and, if so I need to run several stores, like 4S stores will generally be in relatively far from the urban areas, we work more busy, I hope to be able to find a comprehensive sales of all types The auto sales shop to avoid a lot of the way I run, I do not know the friend know that Beijing has no such 4S shops, in what position, there peripheral buses, most grateful!

我计划今年买辆小车，网上查朋友询问现在基本上有了几款车在待选范围，我准备去销售汽车的店再看看，但我听说一家店就销售一种品牌的车，如果是这样我就需要跑好几家店，好像4S店一般都在离市区比较远的地方，我们工作较忙，我希望能找到一家综合销售各种类型的汽车销售店避免我跑好多的路，不知道那位朋友知道，北京有没有这样的4S店，在什么位置，周边有没有公共汽车，万分感谢！
