A series of eight tracer experiments were carried out over one year (1983) on a low energy, macro-tidal beach in South Wales, UK. Tracer movement was monitored and 30 pebbles adjacent to coloured tracer pebbles were measured. Measurements were of the A, B, and C axes, roundness, Maximum Projection Sphericity and Oblate-Prolate indices. Analysis shows that through time, the percentage rejection of these properties increased. It is theorised that the surface tracers are ’misfits’ or ’rejects’ which have not found their equilibrium position in the pebble facies.

油页岩的开发利用可追溯到17世纪。到19世纪时，油页岩矿石的年开采规模达百万吨。20世纪70年代，随着第一次、第二次石油危机的发生，油页岩开采量急剧增加，1980年达到4540万吨的历史高峰。但随着油价下跌，油页岩逐渐失去竞争力，开采量一路下滑。自2000年后，油页岩开采量又逐步增加，目前每年的矿石开采量达到3500万吨。我国油页岩资源总量大，可利用的潜力大，若进一步加强开发利用技术攻关，使其生产

美智子种燕麦，和丈夫小野一郎共同扶养两个孩子。大的叫五一，二的叫六二，均是从他们的生日撷取的名字。五一年长六二三岁，在日本他有继承土地的权利，而六二没有，六二在户籍上是次子，次子都没有继承权。 一郎曾为这事苦恼，美智子更苦恼。六二体弱，她不知道她和一郎百年以后，六二该怎样生活。但是这一天机会来了。一郎一进院门，手上的泥巴都没洗就跑到美智子跟前，递给美智子一张招贴画，他洪钟一样的声音，敲得美智子耳
