| 1 | Accuracy assessment of four cloud-free snow cover products over the Qinghai-Tibetan Plateau显示文摘Four up-to-date daily cloud-free snow products–IMS(InteractiveMultisensor Snow products),MOD-SSM/I(combination of the MODIS andSSM/I snow products),MOD-B(Blending method basing on the MODISsnow cover products)and TAI(Terra–Aqua–IMS)–with high-resolutionsover the Qinghai-Tibetan Plateau(QTP)were comprehensively assessed.Comparisons of the IMS,MOD-SSM/I,MOD-B and TAI cloud-free snowproducts against meteorological stations observations over 10 snowseasons(2004–2013)over the QTP indicated overall accuracies of 76.0%,89.3%,92.0%and 92.0%,respectively.The Khat values of the IMS,MODSSM/I,MOD-B and TAI products were 0.084,0.463,0.428 and 0.526,respectively.The TAI products appear to have the best cloud-removalability among the four snow products over the QTP.Based on theassessment,an I-TAI(Improvement of Terra–Aqua–IMS)snow productwas proposed,which can improve the accuracy to some extent.However,the algorithms of the MODIS series products show instabilitywhen identifying wet snow and snow under forest cover over the QTP.The snow misclassification is an important limitation of MODIS snowcover products and requires additional improvements. | Xiaohua Hao Siqiong Luoa Tao Che Jian Wang Hongyi Li Liyun Dai Xiaodong Huang Qisheng Feng | 2019 | International Journal of Digital Earth2019，12，4： | 2 |
| 2 | Photo-induced Alignment Behavior of Azobenzene-containing Polymer Films with Different Cross-linking Degree显示文摘与各种各样的取代者和交叉连接的某些数量包含偶氮苯组的非结晶的共聚物的三个系列有能力的丙烯酸的组被准备。cross-linked 聚合物电影被丙烯酸的组的热聚合在共聚物,由控制 cross-linking 反应的时间,这些电影能与不同 cross-linking 度在期间被做获得(从 0 ~ 32% ,它被英尺红外系列测量监视) 。这些电影的导致相片的排列过程在 442 nm 与线性地极化的光在照耀下面被执行,并且导致相片的排列率上的 cross-linking 度的效果被调查。导致相片的排列的动力学与双性人一起被分析指数的曲线试穿。因为 cross-linking,导致相片的排列率和这些电影的最大的发射度减少了。为 cross-linked 样品,在重复了“写”并且“擦掉”周期以后,而且,他们发射度的浸透的价值保持不变,这被发现。调查结果表明电影罐头的 cross-linking 有效地由极化的光在照耀期间制止偶氮的聚合物的趋光性的集体运输。在 cross-linking 度和偶氮的聚合物的导致相片的排列行为之间的关系详细被讨论。 | Jing Shena Jin-tang Huang Yan-hua Luoa Qi-jin Zhang Ke-yi Wang | 2008 | Chinese Journal of Chemical Physics2008，21，5： | 1 |
