Fat drippings create smoke that is filled with carcinogenic polycyclic aromatic hydrocarbons, or PAHs. When the smoke envelopes the food, it transfers the PAHs onto the surface of the meat. And when meat, chicken and fish are grilled at high temperatures for long periods of time, compounds inside the food react and create heterocyclic amines, or HCAs. HCAs are worrisome because in lab studies they've been shown to trigger breast, colon and prostate tumors in rats and mice.

滴下来的油脂产生的烟雾充满了致癌的多环芳烃，简称PAHs，当烟雾环绕在食物周围的时候，这些多环芳烃也附着在了食物的表面，当猪肉，鸡肉或是鱼肉在长时间的高温烧烤时，这些食物本身所含有的成分产生了化学变化生成杂环胺类物质，简称HCAs，这类物质相当的麻烦，因为实验室研究发现它们会引起大鼠和小鼠乳腺，结肠以及前列腺部位的肿瘤。

This paper deals with and summarizes the research and importance of ductile shear zones and presents the future direction and aim for the research of the ductile shear zones around the world. Four aspects of studies of the ductile shear zones have been proposed in this paper as follows:(1) The stress environment including the mineral assemblages, deformation, stress-shearing parameters;(2) The major element sequence and activation under condition of stress;(3) The variations of trace elements and REE, their transportation distributions under strong natural deformation as well as variations of mineral crystal parameters, which can also control the element changes during the ductile deformation;(4) The relationship between element migrations, activation and stress, which will present the new evidences for the studies of dynamic diagenesis and mineralization as well as the studies of evolution of ductile shear zones developed in middle and low levels.(5) The analysis of elements and isotopes in mylonites on the micro-scale are crucial for the understanding of component migrations during the mylonization.
