中文摘要:
从几个人获得的超过 20 头发海滨被非侵略的微质子的导致的 X 光检查排放(PIXE ) 为探查钙和硫分发和模式分析。在女人的硫内容“而 Ca 的水平在髓质核心是高得多的并且在男、女的头发两个都展出每日的节奏,沿着纵的轴的 s 头发显示出每月的节奏。逐渐地,到根的从尖端的减少在流的过程和更多的 Ca 放的 Ca 内容能与白头发相比在黑头发被发现。
英文摘要:
More than 20 hair strands obtained from several people are analyzed by non-invasive micro-proton induced X-ray emission (PIXE) for probing calcium and sulfur distribution and pattern. The sulfur content in woman's hair along the longitudinal axis shows a monthly rhythm whereas the level of Ca is much higher in the medulla core and exhibits a daily rhythm both in male and female hair. The Ca content gradually decreases from the tip to the root position in the shedding process and more Ca can be found in black hair compared to white hair.
