Then quality upgrading scheme was explored in order to solve the high content of sulphur and nitrogen in pyrolytic oil, low flash point as well. Yields of pyrolysis of scrap tires in a pilot-scale rotary kiln under 550℃were firstly summarized. Then elemental composition and physiochemical properties were analyzed on both pyrolytic crude oil and its fractions. Based on these researches, the feasibility that pyrolytic oil is used as fuel was discussed. From FT-IR spectra the functional group compounds were generally acquainted, and by column chromatography analysis chemical compositions were clearly known. Then through GC analysis the absolute content of BTX in pyrolytic crude oil was defined.

本文首先考察了中试回转窑550℃下的废轮胎热解产率及热解原油的元素组成和理化特性，对其作为燃料使用的可行性进行了分析；通过实沸点蒸馏研究了轻质、中质馏分热解油的基本特性：红外分析得出了有代表性馏分热解油的大致官能团组成形式，对热解油的强芳香性和部分不饱和性有了整体了解；化学族组成分析进一步了解了热解油内在化学族组成和含量，对热解油的内在性质有了更为深入理解；气相色谱分析对热解油中富含的苯、甲苯和二甲苯进行绝对定量，为热解油提取BTX化工原料的经济性提供了参考。

It is obvious that a 印张 in the same location on the color is stable, but it is going on inside with the job of printing variables there.

较着一个印张上同一个场所上的色不不梢颜色是安定的，但却与息业不梢质爆发的印刷不恒度有必定的干系。

No one's quite figured out how they help, but they do know that carbs provide your brain with a source of tryptophan from which it can make the sleep-inducing neurotransmitter serotonin.

还没有人能够明确指出它们是如何产生作用的。但是已经确定碳水化合物能够给你的大脑提供一种帮助睡眠的色氨酸，增加羟色胺神经递质。

The structure of SRP was tested by PyGC-MS and FTIR. The results showed that the group of －SO3 was grafted onto the surface of the scrap rubber powder.

利用高分辨裂解气相色谱－质谱联用仪和FTIR对SRP的结构进行了分析，测试结果表明，SRP已接枝上磺酸基团。

Shelf stone is not as long as the micro-everything is good, but of course, should be quality, color, shape of the water stone three factors fully with, but also and must have a sense of weight than larger stones as well as the lack of a sense of power could add a better shape .

博古架的石不是只要微型什么都好，而当然应该把质、色、形的水石之三因素充分具有，又且必须具备比大型石缺乏重量感乃至力量感的方面可以补充的更好地形态。

Objective To develop a method for simultaneous determination of amphetamines and ketamine in biological specimens by liquid chromatography-tandem mass spectrometry.
