This paper uses SHDOM (Spherical Harmonics Discrete Ordinate Method) to calculate the nadir bidi-rectional reflectance distribution function (BRDf) of the cumulus and stratocumulus fields at the wave-lengths of 0.67 μm and 2.13μm, and discusses the impact of cloud inhomogeneity on BRDf. The cloud fields are adopted from I3RC Phase II, which are used to compare 3D radiative transfer models. The simulation results show that the cu field has 6% abnormal BRDf values (BRDf>1) with the increase of solar zenith angle. further analyses show that grid cells whose BRDf is greater than one gather to-gether at the local trough of the top of cloud. These regions can receive not only the direct incident solar beam, but also the beam scattered by the higher cloud of its neighborhood. Hence, the BRDf of those regions is enhanced. The abnormal BRDf phenomenon shows that the cloud inhomogeneity can result in inconsistency between satellite observation and plane parallel theory, implying that the re-flectance observed by high resolution satellite is maybe enhanced by the cloud 3D effects. Thus one should take this fact into account when using the product retrieved by these data. The dominant solar zenith angles are quite large in the mid-high altitude area, and the impact of cloud inhomogeneity on these areas may be more significant.

在集中供热系统中,一次网是指从热源出发,经过供水管道等设备后,提供热量给二次网交换的热水管路系统;二次网是指通过供暖设备、散热器和管路等设备,将热水供应到各个供暖区域的管路系统。在二次网小区换热站中的换热器性能随着使用时间的推移,性能有所下降,原因是换热器中形成污垢引起,加大了循环泵的功耗,增加了运行成本。在换热器定期运行中,为了实现对小区换热站中的换热器管壁结垢情况进行监测,文中设计了一种监测换热器污垢热阻在线监测设备的方案,该方案采用单片机AT89C52和DS18B20温度传感器组成下位机并进行编程,上位机采用VB语言来进行设计,通过试验证明该方案可以实现对换热器污垢热阻的在线监测。

Because of their elasticity， light weight， little cost， and wide-area applications， besides that a notable increase in power conversion efficiency （PCE）， organic solar cells have recently caught the concern of numerous researchers. In the current project， we created a variety of organic small compounds as donor materials by using Gaussian 09. Our design approach entails swapping the core part， which is benzothiadiazole （BT）， based on a derivative of oxadiazole， as the terminals on both sides of the prototype compound （RM） with a variety of fragments to improve the electronic and optic characterization and performance for PCE in organic solar cells. Careful theoretical consideration under density-functional theory DfT and time-dependent density functional theory TD-DET at the B3LYP/6-31G（d，p） basis set was made to find the maximum absorption wavelengthλmax， the efficiency of light harvesting （LHE）， excitation energy (EX)， HOMO and LOMO levels， energy band gap (Eg)， dipole moment （ρ）， the DOS， ionization potential （LP）， electron affinity （EA）， fill factor （Ef）， and open circuit voltage (Voc) of molecules RM and TSstudied in a methodical manner. Calculated values revealed that proposed compounds T1-T4 can be encouraging materials for manufacturing organic solar cells as a donor tiny compound with acceptor PC61BM to predict a rise in power conversion efficiency （PCE） owing to their possession of proper values for some optical and electronic features， like the lowest HOMO level， narrower band gaps， and a greater absorption wavelength compared with the reference model RM.
