發(fā)音:   用"total ratio"造句

例句與用法

  1. The adjusted ratio was 1 : 21 - an improvement from last week , but not as dramatic as the total ratio figure
    修正后的相對(duì)比例為1 : 21 -較上周有所改善，但是改善幅度不及總額數(shù)字的改善幅度。
  2. ( 3 ) the treatment result of no2 - n is good . when the influent concentration of no2 - n is 0 . 01 ~ 2 . 23mg / l , the effluent is less than o . lomg / l and the influence of temperature , hydraulic loading the total ratio of gas and water is small
    ( 3 )生物濾池對(duì)亞硝酸鹽氮的去除效果比較好，試驗(yàn)期間，水源水中亞硝酸鹽氮濃度范圍為0 . 01 2 . 23mg / l ，出水濃度一般低于0 . 10mg / l ，水溫、濾速、氣水比對(duì)亞硝酸鹽氮的去除無明顯影響。
  3. The organization cuts into slices and examines by the in situ pcr , drip protease k 20 ( xl with loomg / ml to digest respectively in pretreatment , increase with normal position positive cell account for total ratio of cell , according to the positive standard cells > 75 % , confirm the lightest digestion time , studying the influence and relationship of different fixation time with protease digesting each other , detecting the mn genotype of the organize slices at the same time
    石蠟切片進(jìn)行原位pcr檢，預(yù)處理分別滴加loom歲血的蛋白酶k20閃消化，以原位擴(kuò)增顯色后陽性細(xì)胞占總細(xì)胞的比值> 75 %為標(biāo)準(zhǔn)，確定最適消化時(shí)間‘ ， ，研究不同固定時(shí)間與蛋白酶消化的相互影響和關(guān)系，同時(shí)檢測(cè)石蠟切片的mn基因型。
  4. In this thesis hydraulic experimental studies and theoretical analyses on the vortex - flow drop shaft were conduced and the following results were accomplished : ( 1 ) in the model test some hydraulic characteristics including the shape of air core in the center of the drop shaft , the radial distribution of water flow velocity and the distribution of pressure on the wall of the drop shaft were measured under the condition of high water head above 250m and large discharge above 1400m3 / s . ( 2 ) a kind of computational method for the spiral water flow in the air core region of drop shaft was discussed and applied and the results agree the experimental data well . ( 3 ) the total ratio of energy dissipation in the drop shaft can reach 90 % and the energy dissipation in every region was discussed quantitatively
    本文通過試驗(yàn)研究與理論分析對(duì)旋流式豎井泄洪洞應(yīng)用于高水頭、大泄流量情況時(shí)存在的一些水力學(xué)問題進(jìn)行了研究和探討，取得以下主要成果：一、結(jié)合小灣工程導(dǎo)流洞改建，對(duì)高水頭( 252m ) 、大泄流量( 1400m ~ 3 s )條件下旋流式豎井中的水流運(yùn)動(dòng)特征進(jìn)行了比較全面的測(cè)量，包括空腔形態(tài)、徑向流速分布及井壁壓強(qiáng)等；二、提出了豎井空腔段螺旋水流水力計(jì)算方法，其計(jì)算結(jié)果與實(shí)測(cè)值吻合良好；三、利用試驗(yàn)與計(jì)算結(jié)果，對(duì)旋流式豎井的消能機(jī)理進(jìn)行了探討，對(duì)豎井各部分的消能能力有了總體認(rèn)識(shí)；四、對(duì)豎井下部消力井的合理井深進(jìn)行了優(yōu)化試驗(yàn)研究，發(fā)現(xiàn)消力井合理深度為0 . 9d左右；五、通過試驗(yàn)研究，歸納出豎井水流總摻氣量估算方法，為導(dǎo)流洞排氣方案的設(shè)計(jì)提供了參考依據(jù)；六、在高水頭、大流量條件下，豎井空腔段下部流速很高，盡管水流螺旋運(yùn)動(dòng)引起的離心力可以確保井壁壓強(qiáng)保持正壓，但空化數(shù)依然較低，因此豎井的空化空蝕始終是工程界關(guān)注的重大問題。
