简介:在使用正在增加兴趣亢奋光谱为植被在的量的描述的数据空间;时间的范围。许多光谱索引正在被开发由最小化背景影响改进植被敏感。叶绿素吸收连续统索引(CACI)是如此的一项措施计算光谱分析在上基于马槽的区域的连续统跨越了由光谱连续统。然而,因为连续统的不同位置被不同用户决定,CACI的不同价值在这个方法被获得。而且,因为当红边在GLCD与变化变了时,连续统的固定位置是坚定的,到象绿叶叶绿素密度(GLCD)那样的农学的参数的CACI的敏感被减少了。一个修改叶绿素吸收连续统索引(MCACI)在这篇文章被介绍。红边变化点(REIP)代替最大的反射点(MRP)在在红外线附近(NIR)在CACI连续统上承担。这MCACI被证明了增加敏感;GLCD的预兆的力量。
简介:以便学习理论周期特征[mmim]/methanol吸收制冷,修改UNIFAC组贡献模型和威尔森建模的DMP(1-methyl-3-methylimidazoliumdimethylphosphate)通过相关被建立试验性的蒸汽压力数据[mmim]在T=280370K和甲醇鼹鼠部分x=的DMP/methanol0.5290.965。利用的吸收制冷的热力学的表演[mmim]DMP/methanol,LiBr/H2O和H2O/NH3被调查,与对方相比,在一样下面操作调节。从结果,一些结论如下被获得:1)发行量比率[mmim]DMP/methanol吸收制冷比LiBr/H2O吸收制冷的高,但是能仍然可接受、可容忍。2)警察[mmim]DMP/methanol吸收制冷比LiBr/H2O吸收制冷,当它比H2O/NH3吸收的高时,在最操作下面的制冷调节的小。3)[mmim]当热来源温度太高,不能驾驶LiBr/H2O吸收制冷时,DMP/methanol吸收制冷与高级警察一起仍然是可得到的。
简介:electrospunpolyacrylonitrile(平底锅)的听觉的抑制性质有不同厚度和孔的nanofibrous膜被调查。健全吸收系数基于ISO10534-2:1998(E)用阻抗试管仪器被测量。结果显示nanofibrous膜的第一回声吸收频率随背洞的增加或膜的厚度变到更低的频率。而且,穿孔面板的健全吸收性能能被联合极大地与平底锅nanofibrous的薄层改进膜。传统的听觉的抑制材料(泡沫,纤维)与nanofibrous膜涂独自比听觉的材料的在低、中等的频率范围有更好听觉的性能。所有结果证明PANnanofibrous膜是噪音减小的一个合适的候选人。
