I scarce knew in what Manner to receive them; but found to draw our selves in a close Line was the only Way: so we form'd in a Moment: But that we might not have too much Interval, I order'd, that only every other Man should fire, and that the others who had not fir'd should stand ready to give them a second Volley immediately, if they continued to advance upon us, and that then those who had fir'd at first, should not pretend to load their Fusees again, but stand ready with every one a Pistol; for we were all arm'd with a Fusee, and a Pair of Pistols each Man; so we were by this Method able to fire six Volleys, half of us at a Time; however, at present we had no Necessity; for upon firing the first Volley, the Enemy made a full Stop, being terrify'd as well with the Noise, as with the Fire; four of them being shot into the Head, dropp'd, several others were wounded, and went bleeding off, as we could see by the Snow: I found they stopp'd, but did not immediately retreat; whereupon remembring that I had been told, that the fiercest Creatures were terrify'd at the Voice of a Man, I caus'd all our Company to hollow as loud as we could; and I found the Notion not altogether mistaken; for upon our Shout, they began to retire, and turn about; then I order'd a second Volley to be fir'd, in their Rear, which put them to the Gallop, and away they went to the Woods.

我简直不知道如何对付它们。结果，我认为最好的办法是我们互相靠拢，排成一行。于是，我们马上照此行事。为了不致使我们的火力中断太久，我下令只许一半人开枪，另一半人作好准备；如果第一排枪响过后，狼群继续向我们冲来，就开第二排枪；同时，在开第二排枪时，那开第一排枪的一半人，不要忙于装他们的长枪，而是应该抽出手枪，作好准备。因为我们每人身上都有一支长枪和两支手枪。用这种办法，我们可以连续开六排枪，每次有一半人开枪。然而，当时还没有必要这样做。放出第一排枪之后，我们的敌人就给枪声和火光吓坏了，马上停止了前进。有四条狼被我们打中头部，倒了下来；另外有几条受了伤，鲜血淋淋地跑掉了。这在雪地上可以看得一清二楚。我发现，狼群停止了攻击，但没有后退。这时，我忽然记起有人说过，就是最凶猛的野兽，听见人的声音也会害怕。于是我就叫大家拼命呐喊。这个办法果然很有效。我们一喊，狼群就开始后退，掉头跑掉了。我又下令朝它们背后开了一排枪。这样一来，它们才撒腿跑回树林里去了。这时，我们才有时间重新给枪装上弹药。

If we now bring the gambling table into real life, the "ace of the banker" will be our whole life, and "the second card" will be all the things that we can expect to happen: aging, illness, death, disability/injury/accident, and the key question here is whether we have made plan and prepared for the second card when it turns up!

现在我们把赌桌搬到现实生活里面，"庄家的那一张A"就是我们的一生，而"庄家的第二张牌"就是我们的"生老病死，残"，而关键问题就是，我们有没有为第二张牌做什么准备！

In order to investigate the existence conditions of the robust optimal state feedback of uncertain system, we have to study the problem of GARE, that is the solution existence of the following equation PA+A'P+Q-PMP=0, Q=Q', M=M' In chapter 2, using some preliminary results and properties of the Riccati differential equation, we have established the sufficient conditions for the GARE problem.

在讨论不确定性系统LQL方法的状态反馈解的存在性条件时，引出了第二章讨论一般代数Riccati方程解的存在性问题，对一般Riccati方程 PA+A'P+Q-PMP=0，Q=Q'，M=M'第二章中先列举讨论了Q、M为正、负定各种情况下的实对称解的存在条件，然后着重研究了M、Q不定的情形。

That morning the whole army had admired them, when, at nine o'clock, with braying of trumpets and all the music playing "Let us watch o'er the Safety of the Empire," they had come in a solid column, with one of their batteries on their flank, another in their centre, and deployed in two ranks between the roads to Genappe and Frischemont, and taken up their position for battle in that powerful second line, so cleverly arranged by Napoleon, which, having on its extreme left Kellermann's cuirassiers and on its extreme right Milhaud's cuirassiers, had, so to speak, two wings of iron.

那时是九点钟，军号响了，全军的乐队都奏出了"我们要卫护帝国"，他们排成密密层层的行列走来，一队炮兵在他们旁边，一队炮兵在他们中间，分作两行散布在从热纳普到弗里谢蒙的那条路上，他们的阵地是兵力雄厚的第二道防线，是由拿破仑英明擘画出来的，极左一端有克勒曼的铁甲骑兵，极右一端有米约的铁甲骑兵，我们可以说，他们是第二道防线的左右两铁翼。

复合纳米纤维长丝束制备装置及其制备方法是一种简单、高效电纺制备纳米纤维长丝束的方法，其步骤为将料液输送给支架(3)上的电纺喷头对(1)；喷口相向的电纺喷头对(1)的每个喷头分别施加相反极性的直流高电压；每对相向喷口喷出分别带相反电荷的纳米纤维，并在空中相互吸引、碰撞形成复合纳米纤维，经牵引、拉伸后形成复合纳米纤维长丝束；第一对相向放置的电纺喷头纺丝形成的复合纳米纤维长丝束向下拉伸，并作为接受体与第二对电纺喷头喷出的分别带相反电荷并相互吸引的纳米纤维在空中相遇，被第二对电纺喷头喷出的纳米纤维包裹，经牵引、拉伸后形成两层复合纳米纤维长丝束；依次类推，最后经导丝辊对(2)牵引、拉伸后得到多层复合纳米纤维长丝束。
