Difference of cell-free DNA concentrations was analyzed by one-way analysis of variance using SPSS 10.0 software. There is a significant difference if p value was less than 0.05. The results showed that: 1 DNA concentrations in cell-free lavages supernatants in central lung cancer, peripheral lung cancer and pulmonary benign lesions are (0.83±0.34)μg/ml,(0.66±0.31)μg/ml and (0.59±0.37)μg/ml, respectively.

研究结果如下： 1中心型肺癌支气管灌洗液上清游离DNA量为(0.83±0.34)μg/ml，周围型肺癌为(0.66±0.31)μg/ml，肺部良性病变为(0.59±0.37)μg/ml，经单因素方差分析发现三者支气管灌洗液游离DNA量没有显著差异。

On the basis of the researching of facies、 petrology、 cathodoluminescence analysis, this paper concludes that the terrigenous clastics in Pingyipu Formation were mostly originated from Motianling palaeo-peninsula lied to its north, and sands in distributary channels、 braidedriver in estuaries、 deltas and in littoral zone in hybrids could be derived from Middle-Sichuan Palaeoland with Peng-Guan Highland.

对早中泥盆世浑水陆源碎屑沉积及混合沉积的沉积相、岩石学、阴极发光等研究分析，作者推测，该区陆源碎屑主要来自北边的摩天岭古半岛，而分流河道、辫状河充填及混积滨岸砂则可能以川中古陆和彭灌高地为主要源区。这一点与过去通常认为的主要来自彭灌岛和轿子顶古岛差别较大。

Alter intragastric administration of Ecr to rats, the effect of Ecr on the changes of gastric motility was detected. At the same time, the changes of frequency of electro-physiological activity, as well as expression of c-Fos in nucleus tractus solitari and dorsal-nuclei of the central bulb were also observed. The mechanism of Ecr on gastric motility were also detected by observing the activation of the NTS and DMV.

Among them, 18 lesions were lobar or segmental. The major causes of the filling defects were portal vein invasions or thromboses (10), laminar flows (11), and arterioportal shunts (8). Nine patients had diffuse and mottled filling defects.

楔形灌流缺损的主要原因为肝门脉侵犯或栓塞（10处），薄层血流（11处），和动脉门静脉交流（8处）。9位病人则呈现散在斑驳状的灌流缺损，其中有7位病人与肝硬化有关。

Perennial ryegrass was grown in soil column systems in which soil water content was monitored by regular weighing the column and was maintained within a predetermined range by controlling watering frequency and water amount.Three types of water stress were imposed after the simulated swards were well established,cyclic,sustained and progressive,each of which was further divided into mild,moderate and severe levels,and an adequately-watered column was used as control.

实验植物黑麦草种植于自行设计和制作的圆形土壤柱内，土壤含水量采用称重法加以控制，通过调节灌水次数和每次灌入水量模拟3种类型的水分胁迫，即周期性胁迫、持续稳定性胁迫和渐进性胁迫，并以充足灌水作为对照。3种胁迫又分别设有3个水平，即轻度、中度和重度。

For each strategy, a corresponding exploitation plan of groundwater was designed. Then each designed exploitation plan (except scheme 3) was put into the model for calculation and simulation. The analysis on the forecasting results every plan indicates that:(1) Shuting down the self-provided wells is the most direct and effective method, playing an important role in the land subsidence prevention.(2) The resumption of compressed soil by groundwater artificial recharge is limited. So the artificial recharge can\'t provide essential effect for the resumption of land subsidence, unless the artificial recharge is much more than the groundwater withdrawal.(3) The method of "adjusting the exploitation stratum of groundwater to the shallow" has an obvious effect on the land subsidence prevention.(4)"Sand wells" can increase the leakage recharge for confined aquifer, and thus can slow and prevent the development of the land subsidence.(5) For the groundwater exploitation in Xi\'an, emergency self-provided wells should be managed according to the well spacing of 1600m, 2000m and 1600m, respectively, in the river terrace area, alluvial-proluvial fan area and loess tableland area to exploit the first confined groundwater. Corresponding individual well yield can be set as 2500m~3/d, 1500 m~3/d and 200 m~3/d. Make emergency self-provided wells pump in the dry year and stop pumping groundwater to restore and conserve underground water sources in average years and wet years. In this way, groundwater withdrawal of 162000m~3/d can be obtained to provide for the supplement of water supply in Xi\'an. As a result, the water supply stress can be released in dry years. The groundwater depression formed in the exploiting year can resume in 3-4 years. At the same time, this exploitation manner will not lead to obvious land subsidence.

本文利用所建的模型预测了现状开采条件下未来20年的地下水位和地面沉降的变化，在此基础上，提出了防治西安市地面沉降的五个地下水开采方案，利用所建的地面沉降模型对各个设计方案其进行了模拟和预报，对预测结果的分析表明：①封停自备井是防治地面沉降最为直接和最有效的对策，对防治地面沉降起着最为积极的作用；②采用人工回灌方法使被压缩的土层得到的恢复是非常有限的，对地面沉降不能起到根治作用，只有回灌量明显大于开采量时才能有一定的效果；③&调整开采层次，在浅层取水&对防治地面沉降的效果十分明显；④布设&砂井&可以增加对承压含水层的越流补给量，从而可以有效地缓解和控制地面沉降的发生和发展；⑤对西安市的地下水开采，可在河流阶地区、冲洪积扇区和黄土塬区分别采用1600m、2000m、1600m的井间距布置应急自备井，分别采用2500m~3/d、1500 m~3/d和200 m~3/d的单井开采量，开采第一承压水，在平水年或者丰水年不开采，涵养地下水源，在枯水年启动这些应急自备井开采，在输出分析范围内共可获得162000 m~3/d(5913万m~3/a)开采量，可以有效地补充西安市的供水水源，缓解供水紧张局面，开采年开采导致的下降的水位可在停采3～4年后得到基本恢复，同时，这种开采方式不会造成大的地面沉降量。
