简介：重要信息指差错运动(例如，差错活动时期，紧张，频率，和甚至有活力的背景)当渗出或磨擦时，能被解决差错凿揭示，它是差错运动的结果。地调查包含了样品从QinlingOrogenic带(QOB)的西方的片断的Bailong河差错系统收集；差错凿的44件样品为石英被收集微形态学的分析。这些样品用扫描电子显微镜学的地排放被分析。另外，14件样品为标明日期的热照明被测试。结果证明大多数石英谷物的表面质地被鱼规模，像苔藓的质地，和钟乳石描绘。然而，像皮的破裂和worm-hole-like塑造了的橘子的小数量表面质地被观察。而且，在石英谷物的一些典型conchoids或subconchoidal破裂能被看见。这暗示Bailong河差错在第四级的时期期间反复是活跃的，但是主要运动时期是更新世。标明日期价值的14热照明显示出二个年龄组：343.29-184.06ka和92.18-13.87ka。这些学习数据表明那个差错运动在上新世期间开始了，在更新世的早中间的时期经常发生了，并且运动的山峰频率在早更新世被到达。差错运动被停止在早Holocene终止了。结果为在QOB的西方的片断的自然灾难风险评估是重要的。

简介：在忍冬装饰用的梨树花的di-O-caffeoylquinic酸(diCQAs)的三种类型的抗菌剂活动，繁体中文药(TCM)，在杆菌shigae上，生长被microcalorimetry调查并且比较。diCQAs的三种类型是3，4-di-O-caffeoylquinic酸(3，4-diCQA)，3，5-di-O-caffeoylquinic酸(3，5-diCQA)，并且4，5-di-O-caffeoylquinic酸(4，5-diCQA)。新陈代谢的力量时间上的三diCQAs的效果的质、量的信息弄弯的一些，生长率常数k，最大的热产量力量下午，和产生预定tG，全部的热产量Qt，和生长禁止的比率我B。shigae是计算的。根据一个thermo运动的模型，k，下午，Qt，我和c的相应量的关系被建立。另外，这些药(IC50)的一半禁止的集中被定量分析获得。基于数量活动关系和IC50价值，禁止的活动的顺序是3，5-diCQA>4，5-diCQA>3，4-diCQA。结果说明在C-5的caffeoyl酉旨组是为细菌的房间有一种更高的亲密关系的主要的组的可能性，并且二caffeoyl酉旨的intramolecular距离组织，这也在diCQAs的抗菌剂活动有重要影响。
