In Chapter 5,the pyrolysis of substituted six-membered ring model compound 4-methyl pyridine has been investigated.Instead of detail theoretical analysis of the reaction mechanism,the general results have been proposed from the products distribution and the combination of the pyrolysis investigation of its analogous pyridine.The major products are H_2,C_2H_2,C_4H_2,C_3H_3N and HCN,here HCN is not a primary initial product at low extent of decomposition.The mole fraction profiles of products have been obtained from the near threshold ionization.The pyrolysis of 4-methyl pyridine is initiated from the methyl abstraction and hydrogen abstraction procedures which are associated with the understanding of the soot formation and the NOX precursor correspondingly.

主要产物为H_2，C_2H_2，C_4H_2，C_3H_3N和HCN，其中HCN为非低温时的热解产物；通过近阈值电离并导出物种随温度变化的摩尔分数曲线，更详细地定量地描述了产物随温度的变化。4-甲基吡啶热解主要从母体脱甲基和脱氢两个初始反应出发，一种趋势是形成大质量数的苯并或杂环的多环化合物，有助于了解炭黑形成过程中的复杂化学过程；另一趋势是开环生成小的碳氢和腈类物质，实验得出的含氮物质的种类及随温度变化有助于了解NO_x的前驱物质的形成及其变化规律。

Orthogonal experiment under special condition showed that modifier M has marked effect on properties of no bake sand. Other factors such as modifier B,phosphate concentration and aluminum hydroxide have some impact on properties of binder. It can be found by experiments that strengths of no bake sand are raised notably by binder that modified by modifier B. Modifier B can reduce the strength of no bake sand at high room temperature apart from condition of low room temperature that it can accelerate the reaction and strengthen the sand. Modest content of modifier M in binder has some improvement to anti-wettability of sand. But modifier B has not such notable effect. Electronic microscope shows that near cracks in no bake product there are fibrous shape substances formed when the samples are moistured in high humidity air for sometime.

通过改性剂B对粘结剂自硬砂的性能影响试验发现，改性剂B能显著提高粘结剂自硬砂的强度，在0℃左右很低的环境温度下改性剂M有利于提高自硬砂的反应速度和砂型强度外，但在较高环境温度下，改性剂M均降低粘结剂自硬砂的强度，但是适量的改性剂M有利于改善自硬砂的抗吸湿性，而改性剂B对于改善自硬砂的抗吸湿性的作用不如改性剂M明显，电镜观察发现抗吸湿性较好的自硬砂在高湿度下存放一定时间后，在粘结膜裂纹处会形成一种绒毛状物质，该物质对裂纹具有愈合作用，这种绒毛状物质中具有改性剂M中的某种成分，且含量很高，由此说明改性剂M对提高抗吸湿性有利。

Results show that the antibacterial component belongs to volatile oil、sesquiterpene、phenols and organic acids.

The law of universal gravitation states that/ every particle of matter in the universe attracts every other with a force /which is directly proportional to the product of their masses /and inversely proportional to the square of the distance between them.

万有引力定律说明：宇宙中的每一物质都吸引所有其他的物质，这种引力正比于这些物质的质量，反比与他们之间的距离。2 请将下面的句子翻译成中文。

From this study, we can conclude that:1,there is no significantly difference in pH, [NH3-N], Acetate concentration, propionate concentration, intake, nutrient degradation, blood calcium, TCH and TG.;40g/d stearin in sheep can prominently increase the butyric acid concentration and

通过本研究得出：1，脂肪酸钙、植物脂肪粉以及硬脂肪对瘤胃PH、氨浓度、乙丙酸产量、干物质采食量、营养物质瘤胃降解率、血钙、TCH、TG等方面影响并不显著，但硬脂肪对丁酸以及乙丙酸摩尔比有显著影响(P.05)，植物脂肪粉对血镁浓度也有显著影响(P.05)2，过瘤胃脂肪对营养物质全消化道消化率影响较大，其中脂肪酸钙组与植物脂肪粉显著降低了蛋白消化率，植物脂肪粉能显著降低ADF和NDF消化率(P.05)，但处理组之间差异不显著。

The existent form of pure gravitational field part of matter result in an energy-momentum tensor in gravitational field, which should belong to a part of dark matter because of it can not directly be observed .

以纯引力场形式存在的物质是不能被直接观察到的，因此这部分物质应属于暗物质的一种。

With the indepth research of modern natural science and the development of research and practice of newly-riosen science about human beings, the outlook on matter of the theory of evolution and three dimensions has its prominent limitation in understanding the universe matter, so it has become inevitable for people to understand deeply the physical existence and its nature in the universe.

随着现代自然科学研究的不断深入和新兴人学研究与实践的发展，"进化论"和三维物质观对宇宙物质存在认识上的局限日益突显，对宇宙物质存在形态及其本质认识的进一步深化已成必然。

You said, trustingly and knowingly, from your Nonphysical Perspective, I'll go forth into this perfect Earth time/space reality because I know that it is the perfect environment to produce, within me, natural asking, and I know that when I, in a vibrational way, ask, that God, if you want to call it that, or Nonphysical Energy or Creative Life Force or All-That-Is, answers the vibrational request.

你在来到这个物质世界以前，从你的非物质视角，曾经坚信不疑而且胸有成竹地说过，"我将前往这完美的地球时空现实中，因为我知道，这是能使我自然产生'要求'的完美环境，而且我知道，当我以振动的方式要求时，那个人们常常称之为无所不能的上帝的，那个非物质能量，那个创造生命的力量，那个涵盖一切的真理，就会响应我的振动方式的要求。"
