Applying the Euler method to the equation and particularly using the interpolation technique on variable delay, the Euler approximation is obtained. The discrete Euler approximation is extended to the continuous Euler approximation. It is proved that the Euler numerical solutions will converge strongly to the true solution under the local Lipschitz condition.

对方程应用欧拉方法，特别地对变延迟部分运用插值技巧进行数值离散后，将离散的欧拉格式延拓为连续的欧拉格式，从而得到欧拉格式在局部Lipschitz条件下强收敛到解析解。

The battle once begun, its very various changes,--the resistance of Hougomont; the tenacity of La Haie-Sainte; the killing of Bauduin; the disabling of Foy; the unexpected wall against which Soye's brigade was shattered; Guilleminot's fatal heedlessness when he had neither petard nor powder sacks; the miring of the batteries; the fifteen unescorted pieces overwhelmed in a hollow way by Uxbridge; the small effect of the bombs falling in the English lines, and there embedding themselves in the rain-soaked soil, and only succeeding in producing volcanoes of mud, so that the canister was turned into a splash; the uselessness of Pire's demonstration on Braine-l'Alleud; all that cavalry, fifteen squadrons, almost exterminated; the right wing of the English badly alarmed, the left wing badly cut into; Ney's strange mistake in massing, instead of echelonning the four divisions of the first corps; men delivered over to grape-shot, arranged in ranks twenty-seven deep and with a frontage of two hundred; the frightful holes made in these masses by the cannon-balls; attacking columns disorganized; the side-battery suddenly unmasked on their flank; Bourgeois, Donzelot, and Durutte compromised; Quiot repulsed; Lieutenant Vieux, that Hercules graduated at the Polytechnic School, wounded at the moment when he was beating in with an axe the door of La Haie-Sainte under the downright fire of the English barricade which barred the angle of the road from Genappe to Brussels; Marcognet's division caught between the infantry and the cavalry, shot down at the very muzzle of the guns amid the grain by Best and Pack, put to the sword by Ponsonby; his battery of seven pieces spiked; the Prince of Saxe-Weimar holding and guarding, in spite of the Comte d'Erlon, both Frischemont and Smohain; the flag of the 105th taken, the flag of the 45th captured; that black Prussian hussar stopped by runners of the flying column of three hundred light cavalry on the scout between Wavre and Plancenoit; the alarming things that had been said by prisoners; Grouchy's delay; fifteen hundred men killed in the orchard of Hougomont in less than an hour; eighteen hundred men overthrown in a still shorter time about La Haie-Sainte,--all these stormy incidents passing like the clouds of battle before Napoleon, had hardly troubled his gaze and had not overshadowed that face of imperial certainty.

交锋以后，战争的非常复杂惊险的变化，乌古蒙的阻力，圣拉埃的顽抗，博丹的阵亡，富瓦战斗能力的丧失，使索亚旅部受到创伤的那道意外的墙，无弹无药的吉埃米诺的那种见死不退的顽强，炮队的陷入泥淖，被阿克斯布里吉击溃在一条凹路里的那十五尊无人护卫的炮，炸弹落入英军防线效果不大，土被雨水浸透了，炸弹陷入，只能喷出一些泥土，以致开花弹全变成了烂泥泡，比雷在布兰拉勒出击无功，十五营骑兵几乎全部覆没，英军右翼应战的镇静，左翼防守的周密，内伊不把第一军的四师人散开，反把他们聚拢的那种奇怪的误会，每排二百人，前后连接二十七排，许多那样的队形齐头并进去和开花弹对抗，炮弹对那些密集队伍的骇人的射击，失去连络的先锋队，从侧面进攻的炮队突然受到拦腰的袭击，布尔热瓦、东泽洛和迪吕特被围困，吉奥被击退，来自综合工科学校的大力士维安中尉，冒着英军防守热纳普到布鲁塞尔那条路转角处的炮火，在抡起板斧去砍圣拉埃大门时受了伤，马科涅师被困在步兵和骑兵的夹击中，在麦田里受到了贝司特和派克的劈面射击和庞森比的砍斫，他炮队的七尊炮的火眼全被钉塞，戴尔隆伯爵夺不下萨克森－魏玛亲王防守的弗里谢蒙和斯莫安，第一○五联队的军旗被夺，第四十五联队的军旗被夺，那个普鲁士黑轻骑军士被三百名在瓦弗和普朗尚努瓦一带策应的狙击队所获，那俘虏所说的种种悚听的危言，格鲁希的迟迟不来，一下便倒在圣拉埃周围的那一千八百人，比在乌古蒙果园中不到一个钟头便被杀尽的那一千五百人死得更快，凡此种种迅雷疾风似的意外，有如阵阵战云，在拿破仑的眼前掠过，几乎不曾扰乱他的视线，他那副极度自信的龙颜，绝不因这些变幻而稍露忧色。

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。

Centaurus is a centaur in Greek mythology, whose ancestor is Ixion, the king of the Lapiths. It is said, the king admired the beauty of Hera. but her husband, Zeus, was so jealous that he turned a cloud into the shape of Hera in order to punish him.The king, who is unaware of the truth, slept with the cloud, which latter gave birth to a baby-Centaur.

结果表明，通过NPG共聚改性的PET的结晶能力随NPG用量的增加而降低，热收缩能力有了明显的提高；无定型区增大，获得了在通常情况下不能结晶的PET无定型材料，从而使改性PET薄膜在拉伸时保持较高的取向度，并在高于其Tg时发生解取向热收缩；拉伸温度、拉伸倍数等拉伸工艺对于聚酯薄膜的热收缩率有着显著的影响。

The results showed the crystallinity of the modified PET decreased with the increase of the content of NPG, but the heat shrinkability was improved obviously. Amorphous polyester material that would not crystallize under usual circumstances was obtained, which made the modified PET film to be able to achieve a high degree of orientation during stretching, and it was heat shrinkable when the ambient temperature was higher than its T the effects of different drawing temperature and DR on heat shrinkage of copolyester film was discussed.
