Methods Twenty-three cases of OSAS patients proved by polysomnography were examined with MRI. The cross-sectional area of retropalatal region, retroglossal region, epiglottal region and the lateral parapharyngeal fat pad of RP region was calculated. The thickness of bilateral and posterior pharyngeal wall and other indices were also measured. 30 nonsnoring age-matched normal subjects were selected as the control group. 15 patients underwent turbo field echo T1-weighted imaging during sleep. The images of RP, RG, and EPG were analyzed. Results In oSAS group, the cross sectional area of RP and RG regions was smaller than that of the control group.

应用MRI对23例经多导睡眠监测（polysomnography， pSG）确诊的OSAS患者及30例无打鼾的健康成人进行上气道检查，于轴面图像测量软腭后区（retropalatal region， RP区）、舌根后区（retroglossal region， RG区）和会厌区（epiglottal region， EPG区）的气道截面积，各区前后、左右径及其比值，各区咽侧壁、咽后壁软组织厚度，RP区咽旁间隙（lateral parapharyngeal fat pad，LPFP）截面积，于正中矢状面图像测量软腭厚度、长度及截面积，对两组各项检查指标进行统计学分析。

Total biomass, root morphological index, root activity and the amount of xylem sap excaudate were measured. Results showed that under non-water stress conditions, NH4+-N supply increased the average diameter of rice roots and accumulation of shoot biomass, while NO3--N increased total root absorption area and biomass accumulation in roots.

结果表明，正常水分条件下，NH4+-N促进水稻根系平均直径增大，有利于水稻地上部物质累积；NO3--N则使水稻根系总吸收面积增大，促进根系物质累积；NH4+-N/NO3--N为5/5处理的水稻活跃吸收面积最大，活跃吸收面积比亦最高。

The leaf area of four plants increase gradually along as the light regimes decreases, and Fatsia japonica、 Laurus nobilisl increase more observably than the others, but the biggest incremental number of leaf area of four ground covers was under 6% daylight, under open site was the lowermost.

八角金盘、月桂随光强的减弱叶面积增加的幅度显著，南天竹在24％光强下和58％的光强下相差不显著，24％光强下稍显优势，金丝桃在3种光强下叶面积变化不大。4种地被植物的叶面积均以全光下的值最低，6％自然光下的值最高。

First the theory of grey system and of principle grey prediction model is presented.Based on the data of sown areas of farm crops in Hubei Province for 9 years,the GM(1,1) grey prediction model is established and the precision of prediction is higher by checking the result,so the model may be applied to the prediction of sown areas of farm crops in Hubei Province for futural severe years.

中文摘要：首先介绍了灰色系统理论及灰色预测建模原理，以湖北省连续9年的农作物播种面积数据为基础，建立GM(1，1)灰色预测模型，对湖北省未来8年的农作物播种面积进行了预测，并对预测结果进行检验，预测结果精度较高，可以用来对湖北省未来几年的农作物播种面积进行预测。

Based on data of Yanhe river basin's hydrological stations on precipitation, runoff, soil and water conservation measure area sizes (terrace land, forestation land, grassed land, and silted dam land) from 1950s'-1980s', the basin's monthly precipitation station weightiness indexes and the four main measure areas weightiness indexes through correlation analysis and factor analysis were built.

以建立一种科学的较简单的评价方法为目的，以延河流域水文站20世纪50-80年代30余年降水、径流、水土保持主体措施面积(梯田、造林、种草、淤堤坝)资料为基础，运用相关分析、因子分析等方法，建立了流域雨量站各月降雨量权重指标体系、流域4大水土保持措施面积权重指标值，并构建了以水土保持面积指标、降雨量指标为参数的流域水文响应评价模型，进而分析水土保持措施对流域径流量的效应。

Results : After intervention of MRS, the treated group;the structure of free villi was clear, intra-axial capillary was not congistid, vascular wall was intact, villi area and intervillous space area compared with control group, the difference was significant(p.01).interspace area was smaller than blank group, but without significance.

结果：经黄芪丹参复方成分干预后，治疗组游离绒毛结构清晰，中轴内毛细血管未见充血，管壁较完整，绒毛面积及绒毛间隙面积与模型组相比，差异显著(P.01)，间隙面积比空白组略小，但无统计学意义；底蜕膜层结构清晰，血管数目较多。

The groundwork and achievement of the thesis are as follows:The text analyses the area surveying which is one of the focus questions in the real estate surveying at present and discusses origin and also provides ways at last. The text plays a key role in resolving issuable cases in the area amount of the house.

论文的主要工作及成果如下：商品房销售中的面积纠纷问题已成为购房者投诉较为集中的一个问题，本文在分析房屋面积量算问题的基础上，探讨了该问题的起因，提出了解决方案，对解决房屋面积量算纠纷问题有一定的借鉴作用。

Jambos that nearly no change appeared in its CRR. Similarly, the LWR and LAR in M.candidum and S. jambos decreased while both parameters revealed an increase trend in other species under air pollution. In general, the results from this study demonstrated that P.

在污染区生长的植株叶质量比和叶面积比与清洁区相比存在差异，野牡丹和蒲桃叶质量比和叶面积比下降，而其余3种植物叶质量比和叶面积比上升。

In order to offer the reference of small stream management project of the Dou-zih-pu creek in the future. We get the changing amount presents positive correlation with AOD value to the proportion or area of plant, and it is a Napierian logarithm curve.

在水质和植生比例及面积的相关性分析中，得知植生的面积或比例皆与AOD值变化量呈现正相关，而且是一自然对数曲线的关系，也就是当植生在河道中的比例或面积越高时，净化效果会越高，但最终将达到饱和。

The aim of this study is to quantitatively investigate the effects of both temperature and photosynthetically active radiation on the leaf growth of greenhouse cucumber.

该模型对黄瓜叶面积指数的模拟结果与1∶1直线之间的决定系数R2和回归估计标准误差RMSE分别为0.8792和0.3980，比用积温法和比叶面积法模拟叶面积指数的精度分别提高了37%和74%。
