发表时间：2019-09-05 09:02

有機過氧化物

含有二价OO-结构和可视为过氧化氢的一个或两个氢原子已被有机基团取代的衍生物的液体或固体有机物。本术语还包括有机过氧化配制物(混合物)。有機過氧化物是可发生放热自加速分解、热不稳定的物质或混合物。此外,它们可具有一种或多种下列性质：

a)易爆炸分解;

b)快速燃燒;

c)對撞擊或摩擦敏感;

d)與其他物質發生危險的反應

注:实验室试验中有機過氧化物在密闭条件下加热时易发生爆炸、迅速爆燃或表现剧烈效果,被认为具有爆炸性质。

活性氧

指以氧(当氧:8.00)的形式表达有機過氧化物中存在的氧化能力

自加速分解溫度(SADT）

過氧化物在適于儲存運輸的牢固包裝中開始加速分解的最低溫度。

半衰期

在特定的温度条件下有機過氧化物分解50%所需的时间。

報警溫度(Tem)

必须采取急救措施时(例如清除有機過氧化物)的温度。由自加速分解温度获得。

控制溫度(Te)

産品能夠安全儲存時的最高溫度。由自加速分解溫度推算得到

"I'm not going to try and deceive you," said Balmayne. "I'm going to play the game with all the cards on the table." Our critics are not content with bringing up Aristotle as an authority on the metaphysical controversies of the present day, and reading into him theories of which he never dreamed:279 they proceed to credit him with modern opinions which he would have emphatically repudiated, and modern methods which directly reverse his scientific teaching. Thus Sir A. Grant takes advantage of an ambiguity in the word Matter, as used respectively by Aristotle and by contemporary writers, to claim his support for the peculiar theories of Prof. Ferrier; although the Stagirite has recorded his belief in the reality and independence of material objects (if not of what he called matter) with a positiveness which one would have thought left no possibility of misunderstanding him.168 And Mr. Wallace says that Aristotle ‘recognises the genesis of things by evolution and development;’ a statement which, standing where it does, and with no more qualifications than are added to it, would make any reader not versed in the subject think of the Stagirite rather as a forerunner of Mr. Darwin and Mr. Herbert Spencer, than as the intellectual ancestor of their opponents; while, on a subsequent occasion, he quotes a passage about the variations of plants under domestication, from a work considered to be un-Aristotelian by the best critics, apparently with no other object than that of finding a piece of Darwinism in his author.169 He believed that he could outwit any effort to escape by taking advantage of the landing flares, attached to small parachutes, which Jeff carried as a precaution during his former night hops to the old estate. “He is spelling out something with his flashlight,” Sandy decided, as he saw short flickers and longer dashes of light while the amphibian kept a course within close range but at safe wing distance. It was no wonder that Spain, feeling the serious effects of this state of things, should resist it; and when she did so, and exerted an unusual degree of vigilance, then the most terrible outcries were raised, and wonderful stories were circulated of Spanish cruelties to our people beyond the Atlantic. At this time the Opposition got hold of one of these, and made the House of Commons and the nation resound with it. It was, that one Captain Robert Jenkins, who had been master of a sloop trading from Jamaica, had been boarded and searched by a Coastguard, and treated in a most barbarous manner, though they could detect no proof of smuggling in his vessel. He said that the Spanish captain had cut off one of his ears, bidding him carry it to his king, and tell his Majesty that if he were present he would treat him in the same manner. This story was now seven years old, but it was not the less warmly received on that account. It excited the utmost horror, and Jenkins was ordered to appear at the bar of the House of Commons on the 16th of March, to give an account of the outrage himself; and it would appear that both he and other witnesses were examined the same day. Jenkins carried his ear about with him wrapped in cotton, to show to those to whom he related the fact, and the indignation was intense. He was asked by a member how he felt when he found himself in the hands of such barbarians, and he replied, "I recommended my soul to God, and my cause to my country." The worthy skipper had probably been crammed with this dramatic sentiment by some of his clever Parliamentary introducers; but its effect was all the same as if it had been a genuine and involuntary expression of his own mind. Researches made at the Admiralty in 1889 proved that he really had lost an ear. "I s'pose I've got to obey orders, and buck-and-gag you," said the Sergeant ruefully, as they were alone together in the room. "It goes against my grain, like the toothache. I'd rather you'd buck-and-gag me. But you are to blame for it yourself. You ought to have more sense than lay it into a Lieutenant-Colonel and Provost-Marshal that way. But you did give it to him fine, the old blow-hard and whisky-sucker. He's no more fit for shoulderstraps than a hog is for a paper-collar. Haven't heard anything for a long time that tickled me so, even while I was mad enough to pound you for having no more sense. I've bin aching to talk that way to him myself." "Where are you goin' in sich a devil of a hurry?" the teamster asked. "Smell a distillery somewhere?" "Terrible strict," muttered Jerry despairingly. MRS. G.: You listen tonight and you'll hear a word, Gwen dear. He led her back into the crowd, and once more she felt his arms round her, so light, so strong, while her feet spun with his, tricked by magic. She became acutely conscious of his presence—the roughness of his coat-sleeve, the faint scent of the sprigged waistcoat, which had been folded away in lavender. And all the[Pg 64] while she had another picture of him in her heart, not in his Sunday best, but in corduroys and the blue shirt which had stood out of the January dusk, the last piece of colour in the day. She remembered the swing of his arm, the crash of the axe on the trunk, the bending of his back as he pulled it out, the muscles swelled under the skin ... and then the tingling creep in her own heart, that sudden suffocating thrill which had come to her there beside Harry in the gloam.... Then suddenly she began to plead: "My lord," replied the monk, encouraged by the abbot's energy, "our holy church, thank heaven, is not without one able and zealous advocate. A timorous attitude at this moment would only give fresh vigour to those who seek to abridge its power." HoME 可试看1级C片ENTER NUMBET 002www.jambojuice.cn
