INFERENCE OF IMPURITY RADIATIVE FORCING IN SNOW FROM MULTISPECTRAL TO HYPERSPECTRAL IMAGERS
soil moisture agriculture
2015/9/8
The inference of the radiative forcing of soot and dust in snow has taken on importance in recent years because of
the realization of the climate effects that they have (Hansen and Nazarenko, 2004). ...
SF6 新气痕量杂质气相色谱分析新方法与电力行业SF6 新气推荐标准（A New Trace Impurity Gas Chromatography Analysis Method for SF6 New Gasand Recommended Standard of SF6 New Gas for Electric Power Industry）
SF6新气 痕量杂质 色谱方法 标准
2010/8/17
介绍了一种SF6新气痕量杂质气相色谱分析的新方法。与DL/T 920—2005《六氟化硫中空气、四氟化碳的气相色谱分析方法》相比较，新方法可以从SF6新气中检出更多的痕量杂质，甚至多达17种，且方法高度智能化并便于普及。考虑到SF6新气中某些杂质会影响有关电力设备的使用寿命，提出了电力行业SF6新气推荐标准的方案。
Two-electron transport in a quantum waveguide having a single Anderson impurity
Two-electron transport quantum waveguide single Anderson impurity
2015/8/10
We consider the scattering problem of two-electron transport in one dimensional channel coupled with an Anderson-type impurity. The treatment includes the backscattering of the electrons. We show that...
Doped cap layer effect on impurity-free vacancy enhanced disordering in InGaAs/InP quantum well structures
point defects interdiffusion built-in electric field
2011/5/6
Strong influence on impurity-free vacancy enhanced disordering by the cap layer doping is studied
on the InGaAs/InP quantum well structure with a doped cap layer. The observations are consistent
wit...
The trapping of foreign gas molecules (atoms) by growing aerosol particles as well as by already
formed particles is considered. The trapping coefficients are obtained for both above-mentioned cases....

Impurity Diagnostics Lifetime Spectroscopy
2008/10/30
This paper gives a review of some recent developments in the field of contactless silicon wafer characterization techniques based on lifetime spectroscopy and infrared imaging. In the first part of th...
The effects of boron impurity atoms on nickel Σ 5 (012) grain boundary by first principles calculations
Ab-initio calculation Stress corrosion cracking Tensile test
2010/2/4
Purpose: Impurity atoms in the grain boundary can be responsible for embrittlement or they can strengthen a material. In this work, we have modeled the effect of B impurity on Σ 5 (012) symmetrical ti...

phase-separated glass
2011/5/5
The comparative research of the structure of the phase-separated glasses of sodium borosilicate system with/without the additives of fluorides and phosphorus oxide, as well as of the porous glasses re...
Strongly correlated multiparticle transport in one dimension through a quantum impurity
multiparticle transport one dimension through quantum impurity
2015/8/10
We consider the transport properties of multiple-particle quantum states in a class of one-dimensional systems with a single quantum impurity. In these systems, the local interaction at the quantum im...
