The historiographic turning in the study of children and childhood made it move from the marginal to the central stage not only in the history of children and childhood, but also in the history of industrial revolution.

随着儿童史研究的转型，它才逐渐由儿童史研究的边缘向中心发展，也逐渐由工业革命史研究的边缘迈向中心舞台，童工问题、下层儿童童年生活的转型等问题成为考察和评价工业革命前后英国社会的一个重要视角。

Finally,the following conclusions are gained.(1)The RF irradiation has effect on the relaxation course in a homonuclear system to some extent.(2)The...

研究结果表明：1射频场的照射对同核体系的弛豫有一定程度的影响。2 在射频场的照射下，同核体系的纵向弛豫时间T1 小于无射频场时的T1 ，而横向弛豫时间T2 大于无射频场时的T2 。3纵向弛豫时间T1 随射频场的增强而逐渐减小，横向弛豫时间T2 随射频场的增强而逐渐增大。

From about 550 to 630, the Khazars were ruled by the K?k Turks. They gradually got away from the Western Turkish Empire after the middle of the 7th century and successfully established an independent country. In the early 8th centuries, the Khazars became a formidable political power through outward expansion activities, and finally established a hugeous empire in the southern Russian steppe on the foudation of the Western Turkish Empire's home land.

大约在550年至630年间，哈扎尔人仍处在西突厥帝国的统治之下。7世纪中期以后，他们逐渐摆脱西突厥帝国的统治，建立起自己独立的国家。8世纪初期，哈扎尔人在继承西突厥帝国故地的基础上，通过一系列的对外扩张活动，逐渐发展成为一股强大的政治力量，最终在南俄草原上建立起一个庞大的帝国。

Flooding,as a kind of disturbance events,occurred with higher and higherfrequency over the world.To investigate the effects of flooding disturbance ongrassland vegetation and the soil,a comparatively thorough study was conducted onAneurolepidium chinense grassland in Songnen plain,Northeast China.The studysite was located in Sanjiadian National Rangeland in the territory of Da'an city,Jilirprovince,which was partly flooded in 1998.On the study site,Several transectssubjected to different flooding durations and intensities were designed for thecomparative study among them on such aspects as vegetation characteristics,seedbanks,vegetative propagation of rhizomatous plants,distribution patterns ofpopulations,interspecific relations,and physio-chemical properties of soil.Theresults were as follows:(1)Of the functional group composition of the vegetation,with the elongation of the flooding duration or the increase of flooding severity,theratio of hygric and hygro-mesic plants increase,while that of mesic and mesoxericplants decrease,of Therophytes changed unimodally,of Geophytes increased,whileof Hemicryptophytes decreased.

为弄清草地植被及其土壤环境对水淹干扰的响应，在松嫩平原羊草草地1998年部分遭受水淹的吉林省大安市三家甸子草场内设置了经历不同水淹干扰持续时间和不同水淹强度的样带，并在这些样带之间从植被特征、种子库特征、根茎植物的营养繁殖性能、种群分布格局、种间关系及土壤的理化性质等多个方面展开对比研究，主要结果如下：(1)在植被的功能群组成中，随干扰强度的增加和水淹干扰持续时间的延长，湿生、湿中生类植物功能群的优势度比例基本上是逐渐增加的，中生、中旱生类植物功能群的优势度比例则逐渐减小，而一年生植物的优势度比例呈单峰型变化，地下芽植物比例增加，地面芽植物比例减小。

As shown by the chart of the vertical change of thermophilic and hygrophilous plants, the contents of thermophilic plants gets higher progressively and the content of hygrophilous plants gets lower from the first member to the fifth member of the Xujiahe Formation.

喜湿与喜热植物纵向变化曲线图说明，从须I段至V段喜湿植物含量逐渐增高，喜热植物含量逐渐减少，随着湿度增大，温睛度下降则有得盱的形成，须Ⅲ段与须V段沉积阶段，为最佳成煤时期。

Removed veins research demonstrate the main reason of transplanted vessel stenosis is the hyperplasic of endothelium. Which is a popular reaction when set vein into arteral circulation. It is caused by the transmission of smooth muscle cell to endothelium and proliferate and release extracellular matrix. These are two characteristics in pathology erg middle layer of sue proliferates and migrate to endothelium in early and excel of end thulium aggregate in cater stage. The colic and the motivation of end thulium hyper is the hyper of sac.

在mRNA水平，随着移植术后时间的推移，ECE的表达逐渐增高，手术后1W-2W达到高峰2W后表达逐渐下降，于8W左右趋于平衡，ET-1的表达与ECE的动态变化过程相似，亦于术手1W-2W达到高峰，在8W左右趋于平稳在蛋白质水平，以ET-1抗体免疫组织化学染色结果显示ET-1主要在血管内收细胞及平滑细胞胞浆中表达，尤其是中膜平滑肌细胞更为明显，呈棕黄色颗粒。

In addition, the density difference between Cu phase and Cr phase is also an available factor to cause the formation of band-like microstructures in directionally solidified Cu-1.0%Cr hypoeutectic alloy.

另外， 单相平界面和共晶的带状组织中，合金凝固速率在单相平界面凝固中随着界面液相成分的增加而逐渐增大，而在共晶组织中随着界面前沿液相成分的减少而逐渐减小。

During thawing period, its soil water changes as season changes (the dynamic rule of soil water has the important relation of the season): from June to July the quality-moisture content of soil water gradually increases and reaches the highest, and from July to August it begins to decreases. The range of the quality-moisture content of the ground litter and humus layer is lower than the illuvial horizon whose quality-moisture content is gradually increasing in this thawing season.

在土壤冻土融化期，草类落叶松林土壤水分存在明显的季节性变化，土壤枯枝落叶层、腐殖质层质量含水量比淀积层质量含水量变化幅度大；6～7月份土壤含水量逐渐增加，达到最高；8月份以后土壤含水量开始降低；土壤淀积层质量含水量保持逐渐上升趋势；坡顶土壤质量含水量明显小于坡底土壤质量含水量。

Erum Collagen I reaches low value on the 7th day,increases gradually and peak value on the 21st day, after 21d, falls gradually and approachesthe numerical value in gear on the 35th day after fracture separately. Two groups are inaccordant trend.

D大鼠血清Ⅰ型胶原3d时开始表达增强，7d时表达减弱，达到低谷，然后表达逐渐增强，21d时达到高峰，此后表达量逐渐降低，35d时，基本降至正常值范围：两组的表达趋势一致。

In sagittal plane,the PPSI of each level moved from inferoposterior to superoanterior with an arc trajectory.The PPSI displacements and angular variation increased from L1 to L4,however,these two decreased in L5 simultaneously.The rotation radius had no relationship with lumbar segment.Flexion-extension ROM from L1/2 to L5/S1 increased gradually.

各腰椎屈伸运动时PPSI矢状位上呈由后下至前上的弧线轨迹，L1~L4其位移量和倾斜角度逐渐增大，L5两值同时减小；其旋转半径与腰椎序列无明确关系。L1/2至L5/S1屈伸活动度逐渐增加。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
