在土壤水分胁迫下四翅滨藜的净光合速率、水分利用效率、和光补偿点显著降低,暗呼吸速率减弱。7月份各处理Pn全天的累计值和平均值的大小顺序为:轻度土壤水分胁迫>无土壤水分胁迫>中度土壤水分胁迫>重度土壤水分胁迫,它们的值分别为:7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1)和1.761μmolm~(-2)s~(-1)。8月份各处理的Pn全天累计值和平均值的大小顺序为:轻度土壤水分胁迫>中度土壤水分胁迫>重度土壤水分胁迫>无土壤水分胁迫,它们的值分别为:7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1)和1.705μmolm~(-2)s~(-1)。9月份四翅滨藜的Pn变化趋势于8月份的变化曲线基本相似,唯一不同的变化就是各个处理的Pn比8月份的要高,这可能于9月份气温降低,湿度增大有关。

A little after Noon I found the Sea very calm, and the Tyde ebb'd so far out, that I could come within a Quarter of a Mile of the Ship; and here I found a fresh renewing of my Grief, for I saw evidently, that if we had kept on board, we had been all safe, that is to say, we had all got safe on Shore, and I had not been so miserable as to be left entirely destitute of all Comfort and Company, as I now was; this forc'd Tears from my Eyes again, but as there was little Relief in that, I resolv'd, if possible, to get to the Ship, so I pull'd off my Clothes, for the Weather was hot to Extremity, and took the Water, but when I came to the Ship, my Difficulty was still greater to know how to get on board, for as she lay a ground, and high out of the Water, there was nothing within my Reach to lay hold of; I swam round her twice, and the second Time I spy'd a small Piece of a Rope, which I wonder'd I did not see at first, hang down by the Fore-Chains so low, as that with great Difficulty I got hold of it, and by the help of that Rope, got up into the Forecastle of the Ship; here I found that the Ship was bulg'd, and had a great deal of Water in her Hold, but that she lay so on the Side of a Bank of hard Sand, or rather Earth, that her Stern lay lifted up upon the Bank, and her Head low almost to the Water; by this Means all her Quarter was free, and all that was in that Part was dry; for you may be sure my first Work was to search and to see what was spoil'd and what was free; and first I found that all the Ship's Provisions were dry and untouch'd by the Water, and being very well dispos'd to eat, I went to the Bread-room and fill'd my Pockets with Bisket, and eat it as I went about other things, for I had no time to lose; I also found some Rum in the great Cabbin, of which I took a large Dram, and which I had indeed need enough of to spirit me for what was before me: Now I wanted nothing but a Boat to furnish my self with many things which I forsaw would be very necessary to me.
午后不久,海面风平浪静,潮水也已远远退去。我只要走下海岸,泅上几十米,即可到达大船。这时,我心里不禁又难过起来。因为我想到,倘若昨天我们全船的人不下小艇,仍然留在大船上,大家必定会平安无事。这时就可安抵陆地;我也不会像现在这样,孤苦伶仃孑然一身了。而现在,我既无乐趣,又无伴侣。想到这里,我忍不住流下泪来。可是,现在悲伤于事无济,我即决定只要可能就先上船去。当时,天气炎热,我便脱掉衣服,跳下水去。可是,当我泅到船边时,却没法上去,因为船已搁浅,故离水面很高;我两臂所及,没有任何可以抓住的东西。我绕船游了两圈,忽然发现一根很短的绳子。我惊异自己先前竟没有看见这根绳子。那绳子从船头上挂下来,绳头接近水面;我毫不费力地抓住绳子往上攀登,进入了船上的前舱。上去后发现船已漏水,舱底进满了水。因为船搁浅在一片坚硬的沙滩上,船尾上翘,船头几乎都浸在水里,所以船的后半截没有进水。可以想像,我急于要查看一下哪些东西已损坏,哪些东西还完好无损。首先,我发现船上的粮食都还干燥无恙。这时,我当然先要吃些东西,就走到面包房去,把饼干装满了自己的衣袋,同时边吃边干其他活儿,因为我必须抓紧时间才行。我又在大舱里找到了一些甘蔗酒,就喝了一大杯。此时此刻,我极需喝点酒提提神。我这时只想有一只小船,把我认为将来需要的东西,统统运到岸上去。

Terrain heightened can enhance blocking effect, which lead to strengthen water vapor flux divergence and vertical convection, and cloud water increases but centralizes in the middle-low level. This change intensify accretion of snow by collecting more supercooled cloud water, and rain water converts into graupel by collecting more snow, and dry growth of graupel increase at the same time. Rain water augment because of more graupel melting, and rain water continue to increase by collecting cloud water in the low level.

Based on the national tenth five magnitude project — Suzhou City Water Environment Improvement and Synthesize Demonstration item, we carried out the static simulation test and the dynamic simulation test under the condition of heavy pollution loading rate and low transparency and dissolved oxygen in polluted river of suzhou ancient city district. These investigations were on the base of the formers' work. We analyzed the purification effects and rules of plant floating-bed technology on polluted river water, and also applied the technology to purify the polluted river water in Miaojia River. Conclusions were summed up in the following:The dominance plant option test was carried out among Oenanthe javanica, Lolium mutliflorum and Allium sativum under low temperature condition. The results showed that the Oenanthe javanica was the dominance floating-bed plant under low temperature condition.

At the super-low permeable reservior sandstone of Fu and Yang in Daqing Oilfield, many pore throats exist a lot in the types of compacted and restored flakes and curved lamellas while the pore volume of micropore and the thin, compacted and shrunken throat that contribute little to flow take large scale in the total pore space. Thereof high filtrational resistance is caused by much trouble including high content of reservoir shale, serious sensibility to pressure at waterflooding, remarkable effects of undersaturation and water blocks in micropore. A method with laboratory experiment, theoretical confirmation and field application included was adopted to analyze the non-linear flow characteristics, to reveal the deep mechanism of pinhole enveloping macropore and to provide a new technology of improving the development effect. The outcomes aquired are as follows: Multiple cores with different low and super-low permeability were selected to perform seepage experiments by gas, water and oil. Three fields of flow were observed in the reservoir at different low and super-low core permeability. They are pseudo- elastic flow, transition flow and plastic creep flow. So the concept that there was no correlation of rocky absolute permeability with fluid properties that pasted itself was broken up. Two-phase seepage of water displacing oil in uniform super-low permeability shows that the two-phase seepage zone is narrow.
针对大庆油田扶、杨特低渗透油层砂岩孔隙喉道的大小和形态以压实再生型片状、弯片状喉道分布较广,压实、缩小型细喉道型,微孔不可流动的孔隙体积所占总孔隙体积的比例较大的特点;及储层泥质含量高,注水开发中压力敏感性强、微孔隙欠饱和及水锁效应显著,导致流体渗流阻力增大的问题,本文采用室内实验、理论推证和矿场应用相结合的方法,研究、分析了流体非线性渗流特征,更深刻地揭示出小孔包围大孔的机理及产生原因,并提供了改善开发效果的新的技术方法,取得如下成果:选择不同渗透率的低渗透、特低渗透岩心,进行了气、水和油单相渗流实验,揭示出当岩心渗透率不同时,油层内的流体呈现出拟弹性流变、过渡流变、塑性蠕变三种流变区,从而打破了岩心的绝对渗透率与通过岩心流体性质无关的观点;同类特低渗透岩心的水驱油两相渗流实验表明,两相渗流区较窄。

On the basis of the laboratory data and by widely analysing the formation origin and mechanism of low-resistivity oil/gas reservoir, a point of view is put forward which is not consistent with the idea existing for a long time, that is not all the low-resistivity oil/gas reservoir is shaly sandstone. Fine grains or pure fine siltstone can also form the low-resistivity oil/gas reservoir. And the additional conductibility of clay will become the prominent factor that causes the low-resistivity only when the salinity of formation water is lower. Actual cases indicate that when the salinity of formation water is greater than 300000ppm or so, even ifthere is some clay, its additional conductibility can also be ignored.
建立在实验室数据的基础之上,并通过广泛地低电阻率油气储集层成因和机理分析,提出了与长期以来存在于人们头脑中的思想观念不相一致的看法,即认为低电阻率油气储集层并非都是泥质砂岩,岩石颗粒细小的或纯净的细粉砂岩也可能形成低电阻率油气储集层,并且粘土的附加导电性也只有在地层水矿化度比较低时,才会成为造成低电阻率的突出因素,事实表明,当地层水矿化度高于大约300000ppm时,即使储集层含有一些粘土矿物,它所产生的附加导电性也是可以忽略的。

Also the multi-scale entropy processing and analysis of conductance fluctuating signals acquired by VMEA sensor for five flow patterns with water as the continuous liquid are conducted. The study result indicates that the increase of f o makes oil in water type slug flow occur at lower U sg; for low flow velocity, the continuous liquid inversion occurs at about f o=0.9 and the increase of U sg makes the inversion point move to low oil volume fraction; the multi-scale entropy detail describes the nonlinear dynamic characteristics of oil-gas-water flow patterns and the rate of MSE at low scales sensitively indicates the variation of flow patterns and can act as the efficient criterion of three-phase flow patterns identification.
对水为连续相的5种流型VMEA传感器波动信号进行了多尺度熵分析,研究结果表明:含油率增加可使水包油段塞流在较低气相表观速度下产生;较低流速下的油水相态逆转可发生在油液比为0.9左右,气相流速增加使得逆转点向含油率低的方向偏移;多尺度熵细节可以刻画油气水三相流非线性动力学特性,而低尺度的多尺度熵变化率敏感地反映流型转变,是划分油气水三相流流型的有效准则。
