The results indicate seawater concentration has no effect on absorbency, pH, relative density, dry matter and water contents in Aloe vera leaves. While, seawater stress causes increased MDA and membrane penetration, decreased phytochroms, prolines and NO_3~--N. It is beneficial to plant growth when irrigation was done with 10% seawater, because of higher ratio of K~+/Na~+ and lower ratio of Na~+/Ca~(2+). In addition, the polysaccharide contents in Aloe vera leaves increase twice and triplication under 25% and 50% seawater irrigation respectively, the barbaloin contents increase over triplication in var. 75% seawater and over twice in var. 50% seawater and var. 100% seawater. However, when seawater concentration exceeds 25% the growth of plant was inhibited, biomass decreased, flowering time was deferred, Ca~(2+) content decreased caused by Na~+ accumulation in leaves.

结果表明：在海水胁迫下，库拉索芦荟全叶汁的吸光度、酸度、相对密度、总固形物和水分含量总体上受海水浓度的影响不大；但芦荟叶的丙二醛含量和质膜透性增加，叶绿体色素、脯氨酸和硝态氮含量减少；在10％海水浇灌下，芦荟叶细胞具有较高的K~+／Na~+比和较低的Na~+／Ca~(2+)比，对库拉索芦荟的生长有一定的促进作用；在25％海水和50％海水浇灌下，芦荟多糖含量提高了2-3倍；在75％海水浇灌下芦荟甙含量增加了3倍多，在50％海水和100％海水灌溉下，其含量也增加了2倍多；当海水浇灌浓度超过25％后，库拉索芦荟的生长明显受到抑制，生物量降低，抽苔期推迟，同时，海水浓度的增加也导致芦荟叶中累积大量Na~+，从而使得芦荟叶中Ca~(2+)含量降低，但Mg~(2+)并没有受到海水浓度的影响；用浓度低于75％的海水浇灌库拉索芦荟可以降低剖面深度在0-100cm之间的土壤盐度；其抗氧化保护酶中超氧化歧化酶的酶活力相对保持稳定，过氧化物酶的酶活力在10％海水浇灌下明显提高，随后则下降，而过氧化氢酶的酶活力则随海水浓度的升高而下降。

We knew the results on Friday; my results were not up to my expectations and Science pulled down my overall school's ranking.

在星期五我们知道结果；我的结果不是我所期望并且科学成绩拉下我的整个考试的成绩。

Most of the tourist party spent the afternoon lying on their beds with the shades drawn, but Jim, who was as lean as alley cat, suffered much less than the others from the heat and humidity.

下午，旅游团里的大多数人都拉下遮阳窗帘，躺在床上休息，但是瘦小的杰姆却不太怕炎热和潮湿。

Step 5: Take same strand and tuck under lower loop of the knot and pull down.

步骤 5：采取同样子线和卷起在结的更低的圈之下和拉下。

In addition, keep children away from tablecloths, so they can't pull down hot foods or liquids on themselves.

此外，保持子女远离台布，所以他们也不会拉下热的食物或液体对自己的。

For I can tell you that a cap and gown will keep you down just as surely as these security guards dragging me off this stage are keeping me down...

我可以告诉你，方帽长袍只会束缚你，压制你——一定会的，正如这些保安一定会把我拉下讲台，一定会压制我

Grand talk of sending in an AU force, such as one that ousted a coup-maker last year in the Comoro islands, faded fast.

大义凛然的派遣非盟部队的想法——去年就在科摩罗群岛上把一个政变领导人拉下了马——也很快就不了了之。

So Barak went down from mount Tabor, and ten thousand men after him.

於是巴拉下了他泊山，跟随他有一万人。

From the edge of Szczecin Baltic to the Adriatic side of the Trieste, a trans-continental Europe the 'iron curtain' has been down.

从波罗的海边的什切青到亚得里亚海边的的里雅斯特，一副横贯欧洲大陆的'铁幕'已经拉下。

Then the duke he lets the curtain down, and bows to the people, and says the great tragedy will be performed only two nights more, on accounts of pressing London engagements, where the seats is all sold already for it in Drury Lane; and then he makes them another bow, and says if he has succeeded in pleasing them and instructing them, he will be deeply obleeged if they will mention it to their friends and get them to come and see it.

啊，看这个老傻瓜的这番精彩演出，恐怕连一头牛也会哈哈大笑吧。接下来公爵拉下大幕，对观众一鞠躬，说这场伟大悲剧只能再演两个晚上，因为伦敦方面有约在先，在特勒雷巷戏院里的座位早已预订一空。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
