When thepolynomial has at least two simple real roots,sequences of critical values of timedelays corresponding to each positive root can be derived.

而当该多项式有二个及二个以上的简单正根时，稳定性切换次数主要取决于两方面：一是该多项式的正根的个数，二是该多项式的每个正根对应的临界时滞序列中相邻两项差的大小关系来确定。

On the road Tom he told me all about how it was reckoned I was murdered, and how pap disappeared pretty soon, and didn't come back no more, and what a stir there was when Jim run away; and I told Tom all about our Royal Nonesuch rapscallions, and as much of the raft voyage as I had time to; and as we struck into the town and up through the -- here comes a raging rush of people with torches, and an awful whooping and yelling, and banging tin pans and blowing horns; and we jumped to one side to let them go by; and as they went by I see they had the king and the duke astraddle of a rail -- that is, I knowed it WAS the king and the duke, though they was all over tar and feathers, and didn't look like nothing in the world that was human -- just looked like a couple of monstrous big soldier-plumes.

在路上，汤姆告诉了我，当初人家怎样以为我是被谋害了，我爸又是怎样在不久以后失踪的，从此一去不回；杰姆逃走的时候又是怎样引起了震动的；一桩桩、一件件，原原本本都讲了。我呢，对汤姆讲了有关两个流氓演出《王室异兽》的事以及在木筏上一路漂流等等的全部经过。因为时间不多，只能讲到哪里就算哪里。我们到了镇上，直奔镇子的中心――那时是八点半钟――只见有一大群人象潮水般涌来，手执火把，一路吼啊，叫啊，使劲地敲起白铁锅，吹起号角。我们跳到了一旁，让大伙儿过去。队伍走过时，只见国王和公爵给骑在一根单杠上――其实，那只是我认为是国王和公爵，因为他们遍身给涂了漆，粘满了羽毛，简直已经不成人形――乍一看，简直象两根军人戴的狰狞可怕的粗翎子。

But I was not content with this Discovery; but having now more Courage, and consequently more Curiosity, I takes my Man Friday with me, giving him the Sword in his Hand, with the Bow and Arrows at his Back, which I found he could use very dextrously, making him carry one Gun for me, and I two for my self, and away we march'd to the Place, where these Creatures had been; for I had a Mind now to get some fuller Intelligence of them: When I came to the Place, my very Blood ran chill in my Veins, and my Heart sunk within me, at the Horror of the Spectacle: indeed it was a dreadful Sight, at least it was so to me; though Friday made nothing of it: The Place was cover'd with humane Bones, the Ground dy'd with their Blood, great Pieces of Flesh left here and there, half eaten, mangl'd and scorch'd; and in short, all the Tokens of the triumphant Feast they had been making there, after a Victory over their Enemies; I saw three Skulls, five Hands, and the Bones of three or four Legs and Feet, and abundance of other Parts of the Bodies; and Friday, by his Signs, made me under stand, that they brought over four Prisoners to feast upon; that three of them were eaten up, and that he, pointing to himself, was the fourth: That there had been a great Battle between them, and their next King, whose Subjects it seems he had been one of; and that they had taken a great Number of Prisoners, all which were carry'd to several Places by those that had taken them in the Fight, in order to feast upon them, as was done here by these Wretches upon those they brought hither.

我做出一想到这种罪恶勾当就要呕吐的样子。然后，我向他招手，叫他马上走开。他立即十分驯服地跟着我走了。我把他带到那小山顶上，看看他的敌人有没有走。我拿出望远镜，一眼就看到了他们昨天聚集的地方。但那些野人和独木舟都不见了。显然他们上船走了，并且把他们的两个同伴丢在岛上，连找都没有找他们。我对这一发现并不感到满足。现在，我勇气倍增，好奇心也随之增大。因此，我带了我的奴隶星期五，准备到那边看个究竟。我给了他一把刀，让他拿在手里，他自己又把弓箭背在背上--我已经了解到，他是一个出色的弓箭手。另外，我还叫他给我背一支枪，而我自己则背了两支枪。这样武装好之后，我们就向那些野人昨天聚集过的地方出发了，因为我很想获得有关那些野人充分的情报。一到那里，呈现在我面前的是一起惨绝人寰的景象，我血管里的血不由得都冰冷了，连心脏也停止了跳动。那真是一幅可怕的景象，至少对我而言实在惨不忍睹，可是对星期五来说，根本不当一回事。那儿遍地都是死人骨头和人肉，鲜血染红了土地；那大片大片的人肉，有的吃了一半，有的砍烂了，有的烧焦了，东一块西一块的，一片狼藉。总之，到处都是他们战胜敌人之后举行人肉宴的痕迹。我看到一共有三个骷髅，五只人手，三四根腿骨和脚骨，还有不少人体的其他部分。

It was observed that although the pSym-curred strain HND29SR could not nodulate on the host plant Heinong 33, there was no difference in the root colonization dynamics and density of rhizobium population between HND29SR and its wild-type HN01 or reference strain HN01L in sterilized pot-sand system.

这一现象说明HN01所含共生大质粒不影响其根圈定殖行为，有理由推测影响HN01根圈定殖行为的有关基因可能存在于染色体上或另外两个内源质粒上。

The joints between the half-pipes have rubber seals to stop the contents leaking, and each half-pipe has a vertical pipe connected to it, to introduce or dispose of the fluid concerned.

或者更确切地说，它由两个相对旋转、各只有一半的环形钢管组成（在下面的半个环形钢管固定不动，而在其上的另半个环形钢管则跟着房子一起旋转），两者的接合处由橡胶材料封住以防管内物外漏，此外两个环形钢管各有另一根管道垂直接入，来引入或导出相关的流体物质。
