不同边界条件对多年冻土上限影响的模型试验研究

在全球气候转暖对多年冻土影响的情景下，开展了在多模式下气温升高对冻土上限的影响试验研究。针对不加抛石遮阳棚、加抛石、加抛石遮阳棚3种情况，地表温度均采取基本温度加2次不同升温冻融循环，每次温控指标逐级提高0.5℃，即地表温度3次变化依次按照-16.1～5.8～-13.3℃、-15.6～6.3～-12.8℃、-15.1～6.8～-12.3℃进行，结果表明，加抛石及遮阳棚对多年冻土上限有着明显的影响，冻土上限的变化与气温基本上呈正相关，为寒区道路工程设计与施工提供了理论参考依据。     

江西省钽铌矿床类型及时空分布规律

对本省钽铌矿床根据矿床成因采取四级划分原则进行了详细分类,按成矿作用分内生矿床和外生矿床二大类,按矿床成因及成矿地质条件分二个亚类,根据成矿阶段分七种矿床类型,根据与矿化有关的母岩体的标型矿物分十四种矿体类型,其中蚀变的花岗岩型钽铌矿床是主要类型,其次是伟晶岩型钽铌矿床,细晶岩型矿床因矿物细小,目前尚难利用.各种类型钽铌矿床(点)主要是位于构造隆起带内,分布于怀玉山、武功山、武夷山、于山和九岭等5个钽铌成矿带中.从华力西期至燕山期均有产出,其中以燕山中期为主要成矿期.

活性白云粉生产工艺及其物化性能研究

活性白云粉（ABP）是在白云岩经过破碎、细粉碎、表面改性的基础上得到的一种新型改性功能填料。本文利用河南辉县市的拍石头和张村两地产出的白云岩作为实验原料，对其表面改性的实验方法、改性剂选择及用量、改性条件及改性效果等方面进行了一定的探讨，并且对改性前后的白云石粉体的粒度、比表面积等性能及红外光谱特征做了对比研究。生产工艺和物性测试研究表明：活性白云粉代替轻质碳酸钙作橡胶填料前景广阔；与轻钙相比，活性白云粉的粒度不够均匀，经优化和改善生产工艺条件，可望进一步提高其应用价值。

Study on the relationship between geothermal exploitation and seismic activity in Xi’an region

Based on the analysis of the induced earthquakes in China and abroad, we get some ideas about earthquakes induced by pumping water out of a well or injecting water into a well. The induced earthquakes usually occur near the well, and they are generally small earthquakes. The earthquake sources are shallow, and they belong to the main shock-after shock type of earthquake or the swarm-type of earthquake. The magnitude and the quantity of the induced earthquakes obviously depend on the pressure and the quantity of water pumped or injected. These earthquakes happen as soon as pumping or injecting occurrence, or after ten or twenty days, they may occur at the time of injecting mud or injecting high pressure water when a well is being drilled, or at the time when the ground water is being normally exploited. A large quantity of hot water has been exploited since 1990 in Xi’an, and the quantity of water exploited has been increasing year by year, as a result the groundwater level has been dropping with the water pumped out and the water level is high in summer and low in winter. The earthquakes in Xi’an region belong to the solitary-type and they spread outside Xi’an city where the wells are concentrated but no earthquake happens. The seismic frequency and the energy released have no relation with the quantity of water exploitation or the water level in the well. It is considered that geothermal exploitation does not induce earthquakes in and around Xi’an because of its specially geological condition.
