在亚东县城以南的两处花岗质片麻岩中，锆石U-Pb年龄分别为1149和474 Ma，为原岩和泛非变质事件的年龄，黑云母单次全熔40Ar/39Ar年龄为11.3和11.0 Ma，磷灰石裂变径迹年龄分别为7和8 Ma。

Water-rock interaction demonstrates that, a gold-boring formation , i. e., a set of light metamorphic clastic gritstone, sandy slate, and tuffaceous slate in Wuqiang Runnel Formation, Ban Stream Group, act as the source of gold deposits in South-West Hunan. The gold is originally derived from volcanic eruption materials in Wuling-Xuefeng period; for the typical single gold deposit such as Mobin, which is short of sulphide, chlorine is very important in the metallogenic process; sulphur and chlorine perform as the major negative ions to form complex ions with Au throughout the gold activation and migration movement. The complex ion of chlorine and gold may keep stable in a wide range of temperature; the physical-chemical conditions in typical geothermal fluid system are of deciding significance for gold activation, migration and precipitation.

特定体系的水岩实验证实了漠滨及整个湘西南金矿的成矿元素Au和伴生元素主要源于赋矿围岩-板溪群五强溪组的一套浅变质碎屑砂岩、砂质板岩和凝灰质板岩；首次突破传统认识，证明氯在中低温热液体系中能与Au形成稳定络合物的形式进行运移，因此氯在本区Au成矿过程中起着相当重要的作用；成矿热液流体中Au主要以金硫、金氯络合物形式在溶液中迁移，阴离子∑S、Cl〓对金的活化、迁移及沉淀起主导作用，Au的伴生元素As、Sb在热液体系中与Au形成金锑、金砷络合物有利于金的进一步活化、迁移及沉淀；中低温热液流体成矿过程中，体系的物理化学参数对Au的活化、迁移及沉淀富集起决定性作用。

An amine bactericide, JA-1, is developed to prevent plant gum base hydrofracturing fluids from deteriorating by microorganism s.

华北油田在配制植物胶水基压裂液时，曾使用40%甲醛水溶液(加量0.5%-1.0%)为杀菌防腐剂，未能控制压裂液的霉腐变质，霉变率高达10%以上。

The various metamorphic types represent different tectonic conditions and record evolutionary history and geodynamic process in Altai Hercynian orogenic belt of Xinjiang.

不同的变质作用类型代表了不同的大地构造环境，记录了造山带的演化历史和动力学过程。

The influence of the K/Na modificator on structure and performance of high chromium cast iron was investigated.

考察了K/Na变质剂对高铬铸铁组织和性能的影响，确定了合金的熔炼工艺和热处理工艺，得出最佳的淬火和回火工艺温度(淬火1000℃+450℃回火)。

Of course, in high summer temperatures, tea placed a long time will be granted rancid degenerate.

当然，在温度较高的夏天，茶汤的放置时间长了会发馊变质。
