近日，国际著名期刊《Journal of Hydrology》刊发了中国地质大学环境学院文章教授团队的最新研究成果——“Microbial effects on hydraulic conductivity estimation by single-well injection tests in a petroleum-contaminated aquifer”。该文第一作者为环境学院博士研究生朱...
In work that offers insight into the magnitude of the hazards posed by earthquake faults in general, seismologists have developed a model to determine the size of an earthquake that could be triggered...
Dynamics of fluid and heat flow in a CO2-based injection-production geothermal system
Binary system CO2-water displacement Heterogeneity Preferential flow
2018/3/23
CO2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO2 geological sequestration. Here, a 3-D, “two-spot” pattern wel...
Oklahoma earthquake swarm linked to wastewater injection wells, says study involving CU-Boulder
The earthquake Wastewater Oil Natural gas Underground strata Hydrological geology sewage
2014/7/18
The massive increase in earthquakes in central Oklahoma is likely being caused by the injection of vast amounts of wastewater from oil and gas operations into underground layers of rock, according to ...
Effects of CO2 Injection on the Seismic Velocity of Sandstone Saturated with Saline Water
Biot-Gassmann Theory CO2 Geological Sequestration
2013/3/11
Geological sequestration (GS) of carbon dioxide (CO2) is considered as one of the most promising technologies to reduce the amount of anthropogenic CO2 emission in the atmosphere. To ensure success of...

2012/2/24
An investigation of helicity injection by photospheric shear motions is presented for two active regions, NOAA 11158 and 11166, using LOS magnetic field observations obtained from the Helioseismic and...
Flow Injection Spectrophotometric Determination of Hydrazine in Environmental Water Samples
Flow Injection Hydrazine Spectrophotometry
2011/12/14
A simple, accurate, sensitive and selective flow injection spectrophotometric method for rapid determination of amounts of hydrazine was proposed in this paper, which was based on p-dimethylamino-benz...
Self-injection-locked magnetron as an active ring resonator side coupled to a waveguide with a delayed feedback loop
delayed feedback loop Self-injection-locked
2011/8/26
The theoretical analysis and numerical simulations of the magnetron operation with a feedback loop were performed assuming that the delay of the electromagnetic wave propagating in the loop is constan...
