This is not surprising, given the closer proximity of Pengyang to the Asian inland dust sources; The average content of calcium carbonateis of Pengyang section is not only higher than that of central loess plateau, but also higher the west of Chinese Loess Plateau, which reflected Pengyang loess had been deposited by near Liupanshan\'s substances that contained more calcium carbonateis; The content of diffluent element of 10m depth in the section increased fast, which indicated that the modern eluviation and the leaching depth of loess may be stronger than our guess; The soil growth index can reflect the intensity of soil forming and the climatic changes; The "abrupt chang" of glacial and interglacial period was caused by strong soil-forming processes that enlarged the discrepancy of granularity between loess and paleosol. However, the magnetic susceptibility nearly cannot reflect the existence of S_8 and the magnetic susceptibility of S_7 is highest in the whole section, which is inconsistent with other studies that S_5 has the highest magnetic susceptibility.Thin-section examination shows that the micro-texture of the soil layers is divided into both cementing texture in S_7, S_5 and S_1, and granular texture in all others.

与其它剖面相比，彭阳剖面粒度总体上要比东部的洛川、西安，甚至西部的兰州、新疆东湾要粗；CaCO_3平均含量不仅高于黄土高原中部，也高于高原西部，反映出本剖面富含碳酸盐的六盘山近源沉积起到了很重要的作用；易溶元素含量在剖面10m处快速升高，淀积特征明显，反映出黄土受现代淋溶成土作用影响较大，黄土直立、疏松、多孔特性和高温与多雨组合的气候特点，使得元素淋溶、淀积的强度和深度超出了传统的认识和判断；烧失量与其它指标相比，不仅能区分冰期、间冰期；而且能够区分出次一级的冰阶、间冰阶，有较高的分辨率；土壤发育指数、红度能够反映土壤强度差异，是反映气候波动的较好指标；然而，磁化率不能反映古土壤S_8的存在，且S_7的磁化率在全剖面中最高，这与大多剖面S_5磁化率最高的特点不一致。4。

The complete wind turbine speed control firstly proposed here also improves the tracking effect of wind turbine rotating speed to variable wind speed. Wind turbine rotating speed synchronized power observer compensates the power ripple of wind turbine resulted in inverter dead time. A low pass filter used at the output of MPPT controller smoothes the speed reference, which makes the rotating speed of wind turbine more stable.

本文首次提出的变转速扰动的MPPT控制提高了风车最大功率点追踪的快速性和稳定性，风车完全转速控制提高了风车转速对变动风速的跟踪效果，转速同步风车功率观测法消除了逆变器死区所造成的风车功率波动的影响，带有低通滤波器的MPPT控制器使得风车的转速更加趋于平稳。

On the condition that the axes of two chain wheels are in the same horizontal plane, the paper considers that the mesh drive of chain and chain wheel is equal to single small angle movement of four-rod mechanism every time on tight side.

在两链轮的回转中心同处一水平面的条件下，视紧边每一时刻链条与链轮的啮合传动为四杆机构作小转角的单向运动，建立起相应的链条速度模型，并据此分析了影响链传动中链条速度波动的因素，得到了一些有益的结

Another summer, another failed ministerial meeting in the Doha round. Nine sweat-soaked days of late-night negotiations, swirling rumours, tempers lost and regained – and an unusual surge of optimism halfway through – in the end came to nothing.

又一个夏季，又一次失败的多哈回合部长级会谈。9个汗流浃背的日子，延续到深夜的谈判，纷乱的谣言，剧烈波动的情绪——还有中途乐观情绪的异常高涨——最终却一无所获。

But the first decade of the 21st century has generally been defined by uncertainty and fluctuation, from the return of the mini, to the more austere midi showing on catwalks now.

但是，21世纪的头十年充满太多的不确定和波动的因素，所以T台上的裙子的式样也从迷你裙的回归而到如今更简朴的中长裙。

The decision to complete the single market, with the signing of the Single European Act in 1986, lent new force to the belief, long held by many Europeans, that a closely integrated group of economies would have much more to gain from lack of exchange rate fluctuations than from occasional exchange rate realignments.

随着1986年签署的欧洲单一文件，实现统一市场的决定增强了长久以来多数欧洲人所持有的信念，即与汇率非经常性的调整相比，紧密结合的欧洲经济集团更能从汇率波动的减少中获得更多的利益。

The result shows that gravity wave excited by the tropopause forcing can propagate stably to the mesosphere through the stratosphere so that the energy and momentum can be transferred from a region to another. In the propagation, gravity wave undergoes growth, overturning, convection and breaking. The breaking of gravity wave is the important source of convection and smallscale waves, and convective instability and overturn are the character of nonlinear phenomenon.

分析结果表明，从对流层顶激发的重力波能稳定地经平流层传到中层顶，从而将能量和动量从一个区域带到另一个区域；在向上传播过程中，重力波经历了发展、位温翻转、对流直至最终破碎的演变；重力波的破碎是对流和小尺度波动的重要的源，对流不稳定和翻转是非线性现象的一个基本特征。

When Frederick Delius explained his master piece "Summer in the courtyard" he quoted an anonymous poem," Roses and lilies, countless fragrant flowers, butterfly flashing wings, coming through the flowers, the brown bee dancing in the warm summer air, gently flowing river beside of old trees, the sound of birds coming through distance ..."

音乐家戴留斯在对其所作管弦乐《夏日的庭院》解释的时候曾引用过一首无名诗：&玫瑰与百合，无数芬芳的花朵，彩蝶闪动翅膀，往返穿梭于花丛中，金褐色的蜜蜂在温暖波动的夏日的空气中嗡嗡飞舞，老荫树下，河水缓缓流过，水鸟清越的啼声远远传来。…。。&。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
