以邪恶、异教崇拜以及撒旦思想为其主要诉求，通常在歌词含有反基督、反宗教的倾向即被归为黑金属，除了传统重金属固定乐器之外，经常会使用其他乐器如钢琴、小提琴，或歌剧的女高音，在歌曲中营造出一股诡异又吓人的恐怖气氛。&黑金属&以来自北欧的重金属团体最具代表性。1、启蒙黑金属：在八十年代初，英国的地下重金属乐队Venom，在音乐中明确宣扬了对撒旦的崇拜、对战争的渴望，并且是由他们第一次将&Black Metal&这个名词带到金属圈内，为日后的黑金属乐队指明了音乐方向；瑞典同样出现了两支启蒙型的黑金属乐队，Bathory和Celtic Frost，他们的音乐已经基本上具备了原始黑金属的特点：粗糙、暴虐、邪恶！而Bathory的第一张专辑也被誉为是第一张黑金属唱片。不能不提的是丹麦的Mercyful Fate，他们虽然对日后的原始黑金属没有什么过多的影响，但是却对歌特黑金属、交响黑金属、歌特金属有着榜样的作用。

Guo Guichun, the Chinese expert in scientific realism, considers that different from the argumentation between the former traditional realism and the antirealism, the divarication from the contemporary scientific realism with the antirealism is no longer about whether or not acknowledgement of existed objective world independent from the will of the people, or ontology question and so on in material first nature, but about the acknowledgment of world existence, acknowledgement of the perceptual experience provided for objective world information, acknowledgement of the science as the rational cause, acknowledgement of the progressiveness and success of science, acknowledgement of that under the premise of theory entity playing key role in the cognition process, to understand why the science can obtain success, approach the truth gradually, or the real existence of theory entity, or actuality of the scientific goal, so on in the divarication of significant epistemology .

中国科学实在论研究专家郭贵春认为：与既往的传统实在论与反实在论之争不同，当代科学实在论与反实在论之间的分歧，不再是关于是否承认存在着独立于人心的客观世界，是不是物质第一性等本体论问题上的分歧；而是在承认世界的存在性，承认感性经验(来源：ABba0aC论文网www.abclunwen.com)能为我们提供客观世界的信息，承认科学是一项合乎理性的事业，承认科学的进步性与成功性，承认理论实体在认识过程中能起重要作用的前提下，理解科学为什么会取得成功，为什么会向着逼近真理的方向发展，理论实体是否真的存在，科学的目的究竟是什么等重大认识论上的分歧。

The removal of silica to produce pure iron concentrates is a dominant way for iron-ore dressing at present. In order to solve the problems, such as bad selectivity, sticky bubbles, weak collectability at low temperature by using fatty amines to fulfil the reverse flotation of iron ore in a iron Mine in AnShan.

提铁降硅生产高纯铁精矿是当今铁矿选矿的主导发展方向，为解决鞍钢某铁矿使用常规脂肪胺类阳离子反浮选工艺存在的选择性较差、浮选泡沫粘度大，以及矿浆需要加温等实际问题，本文围绕开发或寻找新型高效阳离子反浮选药剂进行了系统的试验研究。

According to classical thermodynamics, the energy relations between forward and reverse Carnot cycles between two isothermic reservoirs satisfy the principle 'it is equal in quantity and opposite in direction'.

按经典热力学，工作在两恒温热源间的正、反卡诺循环能量满足：&大小相等，方向相反&的原则，而实际热机、制冷机与热泵，由于热阻、摩擦、涡流、热漏等不可逆因素的存在，正、反卡诺循环能量不再满足此原则。

Objective: To explore the mechanisms resulting in the recurrence of urethral scar which make urethral strictures difficult to be cured, a series experiments were conducted to find potential effective factors involved in urethral scar formation and degradation, including the studies of extracellular matrix component of urethral stricture scar, the characteristics of urethral scar fibroblast, and the effects of urine on urethral fibroblast in vitro, as well as the studies to compare the difference of collagenase activity, type Ⅰ collagen and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the tissues and cultured fibroblasts from normal urethra and strictured urethra respectively, and the studies to investigate the effect of antisense TIMP-1 oligodeoxyonucleotide on cell proliferation and collagenase activity of urethral scar fibroblast.
