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.

By use of titration analysis, the thesis investigated various factors such as isocyanate, PE molecular weight, reacting substance molecular ratio, reacting temperature and time etc. influencing upon prepolymerization step. It was found that 2, 4-tolulene diisocyanate and 4, 4'diphenylmethane diisocyanate is more rapidly reacted with PE600 than HDI. With PE molecular weight increasing, the reacting temperature or time should be raised or extended relevantly. Thus PE2000+2HDI pre-polymerization should be better carried out under some catalyst, for example, Triethylene diamine , Dibutyltin dilaurate and Tin octoate were used.
首先采用滴定分析方法对WRPU预聚反应的影响因素进行了研究:芳香族二异氰酸酯TDI、MDI比脂肪族二异氰酸酯HDI反应活性高,其中TDI在反应初始阶段的反应速率比MDI快,不过随着反应的进行,MDI比TDI反应速率加快,这主要是因为TDI分子中的两个-NCO反应活性差异大所致;二元醇分子量越大,反应速度越慢;聚醚二元醇比聚酯二元醇的反应速度快;当分子量超过2000的二元醇与HDI进行预聚反应时,需借助适当的催化剂来加快反应速度,从而使预聚反应能够顺利进行,分别选择DABCO、TOA和DBDTL三种催化剂进行催化反应,发现不同的催化剂,其催化效果相差较大。

Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental wave's aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.
