Think of the bottom bracket as a focus your arms pulling down and back; helping to pivot and press the rear tire in the ground.

试着想象以B.B。为中心，腿部向下及向后拉的动作有助于将后轮压于地面上，而运用辅助把手，也会增加出力。

Hijacked Jets Destroy Twin Towers and Hit Pentagon Hijackers rammed two jetliners into each of New York's World Trade Center towers yesterday, toppling both in a hellish storm of ash, glass, smoke and leaping victims, while a third jetliner crashed into the Pentagon in Virginia.

被劫持客机摧毁双塔和五角大楼的袭击劫持飞机撞向两到每一个纽约的世界贸易中心大楼昨天，双方推翻了地狱般的风暴灰，玻璃，烟雾和跨越式的受害者，而第三客机撞向五角大楼在弗吉尼亚州。

This idea with self-cultivation as the core, outward of which is self-cultivation, family-regulation, state-ruling and world-governance, inward of which is studying things, induction by conscience, sincerity and impartial heart, eliminated the personal and social barriers and the subjective and objective gap, reaching the spiritual realm of Integrating the inside and the outside.

《大学》作为儒家哲学的一部重要的经典文本，揭示了以修身为根本，修身、齐家、治国、平天下为一体的选德思想，这种思想以修身为中心，向外则是齐家、治国、平天下，向内则是格物、致知、诚意、正心，由此而消除了个人与社会之间的隔阂，主观与客观之间的隔阂，达到&合内外&的精神境界。

Welcomes the establishment and development of the logistics base at Entebbe, Uganda, as a regional hub for common use by missions in the region to enhance the efficiency and responsiveness of logistical support operations, and requests the Secretary-General to report to the General Assembly in the context of his overview report, to be submitted during the second part of its resumed sixty-first session, on economies and efficiencies realized through its utilization and on the increased effectiveness of regional support for peacekeeping operations

欢迎建立和发展乌干达恩德培后勤基地，将其作为该区域各特派团共用的区域后勤中心，以提高后勤支助业务的效率和回应能力，并请秘书长在第六十一届会议续会第二期会议期间提交的概况报告中，向大会汇报利用该后勤基地后经费节省、效率提高的情况，以及向各维持和平行动提供的区域支助效力提高的情况

In the Eogene and Neogene, Qaidam Basin experienced the multiphase tectonic movement; the paleoclimate evolved from warm-humid to arid; the water in the basin was gradually salinized; the depocenter migrated from west to east. The master factors and developmental characters of lithologic hydrocarbon reservoirs have their own particularity. Taking the fine exploration zones of the southwest hydrocarbon-rich depression in Qaidam as the key point, with the analysis of source-rock distribution, sedimentary evolution and sedimentary system distribution, the author proposes that the density difference increases after the fluvial water enters, then clam and bar sand bodies are formed easily due to density flow. Highstand system tract and transgressive system tract below the maximum flooding surface are the main exploration areas of lithologic reservoir.

柴达木盆地古近纪－新近纪经历了多期构造运动，古气候由温湿向干旱演变、湖盆逐渐咸化、沉积中心由西向东迁移的演化过程，地层岩性油气藏的主控因素和发育特征有其特殊规律，以柴达木盆地柴西南富油气凹陷精细勘探区带为重点，通过分析烃源岩展布、沉积演化和主要沉积体系展布，提出咸化湖盆在河流入湖后因密度差较大，易形成密度流等成因的各类滩坝砂体，最大湖泛面之下的高位体系域、湖侵体系域是地层岩性油气藏的主要勘探领域。

Saddle shaped AMF can produce a radial expanding force, which has more effective effect on resisting the pinch effect of self-generated azimuthal magnetic field of arc current. This effect of saddle shaped AMF can keep vacuum arc in diffuse mode under much higher current. So the limiting current interruption capacity of vacuum interrupter can be enhanced.

为了进一步提高纵向磁场对真空电弧的控制作用，本文提出在真空灭弧室的触头间引入从触头中心向边缘逐渐增强的非均匀纵向磁场，马鞍形纵向磁场会对真空电弧产生一个径向扩张力，而纵向磁场分布的合理设计可以使这一扩张力进一步抑制真空电弧自生环向磁场对电弧的箍缩作用，从而使真空电弧在更大的电流时仍能保持在扩散态，使真空灭弧室的极限电流开断能力得以提高。

Based on researching into the classification mechanisms of feedforward single-layer radial basis function and linear basis function networks,the author presents the viewpoints that the RBF centers and widths should be determined through a self-learning procedure,that some new kernels naturally come into being according to which class the labeled patterns are misclassified to.

研究了前向单层径基函数网络和前向单层线性基本函数网络的分类机理，提出了RBF的中心和宽度应通过学习自动确定，在学习过程中根据错分样本被错分入的类别自动生成新的核函数这一观点。

The results show that the temperature of the alloy gradually decreases from the casting mouth to the exit in the roll-shoe gap, and the isothermal line deviates from the shoe side to the roll side.

结果表明：辊靴型腔内合金的温度从入口至出口逐渐降低，合金等温线向工作辊偏移；随着浇注温度的降低，辊靴型腔内半固态区间逐渐增大；为了获得优良的半固态金属浆料，确定浇注温度为710~770 ℃；合金在辊靴型腔内层流运动时，越靠近工作辊内表面，合金的运动速度越快；随着挤压模具扩展角的增大，挤压模具出口型材宽度上中心与两侧边部合金的温度差减小；半固态合金进入模具后呈辐射状逐层向前推进填充模具扩展腔，最后再逐渐向模具出口合拢；为了改善模腔内金属流动速度的不均匀性，扩展角以45为宜。

To help improve public health policies in Britain, Mister Layard has pressed the British government to spend more money on mental health treatment centers. He argues that by helping people recover from mental illness, the government can make a big step in the effort to increase happiness.

为了改进英国的公共健康政策，莱亚德先生向英国政府施压，让英国政府向精神健康中心提供更多的经费，他说，通过帮助人们恢复精神健康，政府就在为全社会创造幸福迈出了一大步。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
