This paper researched the power generation characteristics of PV module by a variety of environmental factors through building a simulation model. Based on this module, it analyzed the effect of environmental factors, such as temperature, light intensity, dust deposition and other factors when the PV module operating respectively. Then, author compared the simulation data with the distributed PV system operating data in Shanghai to verify the reliability of the model. On the analysis of these data, this paper deeply researched the PV module output power and the variation of the attenuation characteristics.
Due to influence of size effect, the force properties in nanoscale are greatly different from those in macroscale and the traditional models of operation are becoming difficult to meet the development of nanoscale manipulation. To provide guiding theory for practical nano-manipulation, the nanoscale forces of contact and non-contact operation of nanowires are analyzed for nano-manipulation in SEM. The Vander Waals models among the probe, nanowire and substrate are modeled according to the force properties in nanoscale, and then the simplified models are simulated with MATLAB. The influence degree of various factors and the relationship of them during the operation are obtained. At last, experimental system is established to verify the correctness of the proposed models.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
