Pressure Stimulated Currents (PSC)in marble samples
Pressure Stimulated Currents (PSC)-Piezo Stimulated Current rocks marble-electricprecursors
2015/9/14
The electrical behaviour of marble samples from Penteli Mountain was studied while they were subjected to uniaxial stress. The application of consecutive impulsive variations of uniaxial stress to thi...
Simulation of polar stratospheric clouds in the chemistry-climate-model EMAC via the submodel PSC
polar stratospheric clouds chemistry-climate-model IMAC submodel PSC
2014/12/9
The submodel PSC of the ECHAM5/MESSy Atmospheric Chemistry model (EMAC) has been developed to simulate the main types of polar stratospheric clouds (PSC). The parameterisation of the supercooled terna...
PSC中商洛方言区考生常见的语音失误分析
PSC中商洛方言区考生 语音失误
2014/9/4
陕南地区蕴藏着极其丰富的方言资源,在这里,中原官话、西南官话、江淮官话等构成了复杂的接触关系。[1]陕南方言以汉江和丹江水系为线自然分成两大块——西部方言片和东部方言片。地处秦岭东段的丹江一带,群山丛岭,沟谷纵横,本来就严重影响了人们的交往,形成了方言之间的诸多差异,加之南部接邻湖北,关中的秦音与南部的楚语犬牙交错,又有多方移民杂居和文化的相应渗透,形成极为复杂的方言差异和种种音变现象。
试析影响PSC信度和效度的因素
效度 PSC信度 音节
2014/9/4
测试的信度指测试结果的可靠性、一致性和稳定性程度。一个高质量的测试,对同样一组被试反复多次测量,其结果应该保持不变。效度是指测试的有效性或准确性,即测试对它所要测的东西准确测试的程度。
对提高PSC“命题说话”测试效度与信度的思考
PSC 命题说话 普通话
2014/9/4
“命题说话”是普通话水平测试(PSC)中测查应试人普通话运用能力的重点和关键。目前,绝大部分地方语言文字工作部门采用“读单音节字词”、“读多音节词语”、“朗读短文”、“命题说话”四项内容测试,免去了“选择判断”一项,“命题说话”的分值由30分调整为40分,这就使“命题说话”成为PSC中分值最重的一项内容,成了PSC的重头戏,这项测试的得分直接决定着应试人普通话水平的等级,这项测试的效度与信度在很大...

2009/2/17
Stratospheric aerosols play an important role in a number of atmospheric issues such as midlatitude ozone depletion, atmospheric dynamics and the Earth radiative budget. Polar stratospheric clouds on ...
Differences in Arctic and Antarctic PSC occurrence as observed by lidar in Ny-Ålesund(79° N, 12° E)and McMurdo(78° S, 167° E)
Arctic Antarctic PSC lidar Ny-Å lesund McMurdo
2009/2/16
The extent of springtime Arctic ozone loss does not reach Antarctic ``ozone hole'' dimensions because of the generally higher temperatures in the northern hemisphere vortex and consequent less polar s...
A 3D-CTM with detailed online PSC-microphysics: analysis of the Antarctic winter 2003 by comparison with satellite observations
3D-CTM PSC-microphysics Antarctic winter
2008/12/5
We present the first detailed microphysical simulations which are performed online within the framework of a global 3-D chemical transport model (CTM) with full chemistry. The model describes the for...
PSC:A Human-Computer Interaction System for Protein 3D Structure Comparison
Human-Computer Interaction System Protein 3D Structure Comparison
2010/12/14
Since protein 3D structures are more conserved than sequences and even functions, analyzing the protein 3D
structure is very important to the understanding of biological processes. With the accumulat...
