Through the calculation and analysis of the tourism economic spatial relation, it found that Liaoning central urban agglomeration tourism economic spatial relation has many problems, such as the central city is insufficient, and the low degree of spatial relations. Therefore, this article puts...

This article firstly measures the tourism economy relations in Shenyang Economic Zone, and summarizes the spatial structure of tourism economy in Shenyang Economic Zone. The results show that Shenyang is in the central position and its tourism resource has obvious advantages. Finally, this paper...

We select 149 rural recreational tourism destinations in Liaoning Province as the samples, and use geographical mathematical method to analyze the travel spatial structure of rural recreational tourism destinations from aggregation degree of spatial distribution, the balance of spatial...

Correlations for calculating diffuse solar radiation can be classified into models with global solar radiation (H-based method) and without it (Non-H method). The objective of the present study is to compare the performance of H-based and Non-H methods for calculating the diffuse solar radiation...

Cryogenic generation is one of the most important ways to utilize cold energy during LNG (liquefied natural gas) regasification. This paper fundamentally investigates LNG cryogenic generation with the Stirling cycle method based on previous studies. A basic process of LNG cryogenic generation...

There are many solar constant values given and adopted by researchers, leading to confusion in estimating solar radiation. In this study, some solar constant values collected from literature for estimating solar radiation with the Ångström–Prescott correlation are tested in China using the...

In the present study, the photon absorption in a suspended photocatalytic reactor was simulated by adopting Monte Carlo method and the six-flux radiation absorption-scattering model. Different photocatalyst concentrations, i.e. uniform concentrations, linearly increasing concentration gradients...

Two models based on Li et al. (2011) are developed for general application in estimating the monthly average daily diffuse solar radiation in China. The validation of these models is performed by comparing with four existing empirical models against the measured data. It is found that the...

Eight models using only the sunshine duration for estimating the global solar radiation on a horizontal surface are evaluated at Changdu, Geer, Lasa and Naqu stations in Tibet, China against the measured meteorological data during 1994–2008. Based on statistical error tests, results show that...
