Actinolite and pyroxene phenocrysts separated respectively, from chlorite-actinolite schist and altered pillow basalt in the E'rou area of the eastern part of the Shuanghu-Longmuco suture zone, yield well-defined 40Ar/39Ar plateau ages of 235.9±2.6 Ma and 232.5±2.4 Ma. These nearly identical ages are interpreted as defining the age of the tectonothermal event of subduction-related collision along the Shuanghu-Longmuco suture zone.

在藏北龙木错－双湖缝合带东段双湖鄂柔地区，获得绿泥阳起石片岩中阳起石矿物的40Ar/39Ar坪年龄为(235.9±2.6)Ma和枕状玄武岩中蚀变辉石斑晶的40Ar/39Ar坪年龄为(232.5±2.4)Ma，两个年龄具有极好的一致性，记录了中三叠世晚期－晚三叠世早期沿龙木错－双湖缝合带发生俯冲碰撞作用的构造－热事件。

Little is known about the influence of minerals and other soil factors on the biocontrol activity of Trichoderma spp.The objectives of this study were to first evaluate the take-all–suppressive activity of T.koningii in field soils representative of the wheat-growing region in the Pacific Northwest of the United States,and then to identify abiotic edaphic parameters that are positively and negatively associated with the biocontrol activity of T.koningii in these soils.Such information will be usefulin selecting sites where T.koningii can be expected to perform optimally;in developing formulations that enhance biocontrol;and perhaps in indicating factors that favor mechanisms involved in the biocontrol activity of this strain such as antibiotic and enzyme biosynthesis.

知之甚少，对矿物和其它土壤因素对生物活性木霉镰刀本研究的目的首先评估全蚀抑制活性t.koningii土壤代表小麦种植区在西北太平洋的美国，然后找出生物土壤参数有积极和消极与生物防治活性t.koningii在soils.such这些信息将有助于在选择地点，可以t.koningii预计进入最佳状态；在发展制剂提高生物防治；或许说明因素，有利于参与机制，在生物防治活动，这株如抗生素和酶的合成。

In the North Ordos basin the sandstone-type uranium deposits developing in the system of sandstone beds of sedimentary facies of braided river course in Midde Jurassic Series,at the same time it happen some show of ore:the alteration zone of chloritization,bleaching decoloration and carbouation of epigenetic alteration,which show of ore are immediate and indirect for uranium mineralizing process.

摘 要：发育于内蒙古鄂尔多斯盆地北部中侏罗统直罗组辫状河相杂砂岩体内的砂岩型铀矿，有一系列较为特殊的与放射性铀成矿有直接或间接关系的成矿地质现象：绿色化蚀变带、漂白退色化带、二次胶结钙化砂岩团块及钙化砂岩断续层与&钙化木&后生蚀变现象；在与铀矿化和与油气的关系认识上存在一定分歧。

The sodium lignosulfonate with low molecular weight which has more hydroxyl groups and sulfonic groups, less methoxyl groups, has better corrosion and scale inhibition performances.

研究表明，分子量较小的木素磺酸钠级份含有较多的羟基和磺酸根、较少的甲氧基，具有较好的缓蚀阻垢性能。

A strain KX6, producing thermotolerant endoglucanase, was isolated from compost. The morpholo-gical identification and 16S rRNA sequence analysis showed it belongs to Streptomyces xylophagus.
