After the reform of China's tax system, in the case of an established local fiscal revenue, due to the differences in local infrastructure, under the influence of different investment and tourism-oriented input and output levels, the crowding-out effect of tourism industry varies. This paper validates this inference, and concludes that the crowding-out effect of tourism over other industries is small in areas with larger tourism scale such as Beijing which is either historical and cultural city, or political and economic center, with an emphasize on tertiary industry development; while the crowding-out effect of tourism over other industries is the largest in areas with smaller travel size, which is either landlocked but rich in tourism resources, or lacks of tourism resources but plays the key position of foreign trade. Regions of medium tourism scale are mostly dominated by secondary industry. Although the investment in tourism has increased in recent years, the propensity of government and private investment is firstly towards local leading industries, thus the production factors needed for development of the tourism industry have been occupied by local leading industries. And finally, the corresponding development strategies have been proposed for tourism industry with different crowding-out effect. © (2014) Trans Tech Publications, Switzerland. Source

The density at a data point is defined based on kernel function. And we introduce weight to refine rough k-means algorithm. Then we construct the formula for calculating local outlier score based on the clusters generated by the refined rough k-means algorithm. We use a synthetic data set and a real-world data set to verify that the new technique for local outliers detection is not only accurate but also efficient. © 2011 IEEE. Source

This study evaluated the anti-oxidant potential of salvia extracts in enhance training rats. The salvia extracts were administered to endurance exercise rats by gavage for 28 days. In addition to antioxidant enzymes activities evaluation, several functional enzymes assays (e.g., LDH, CK and CHE activities) were employed to examine the effects of salvia extracts on the oxidative injury in endurance exercise rats. The results from this study demonstrated that salvia extracts treatment significantly reduced lipid peroxidation, LDH, CK activities levels, enhanced antioxidant enzymes, and CHE activities in the skeletal muscle of endurance exercise rats. Taken together, the salvia extracts may decrease oxidative injury induced by endurance training and display strong antifatigue effect. © 2011 Academic Journals. Source

In this paper, an experimental study of collinear geometry double-pulse femtosecond LIBS was performed on a Ni sample in ambient air in an effort to clarify the contributing processes responsible for the signal enhancement observed in comparison with the single-pulse case. Double-pulse LIBS spectra show a very clear enhancement when an optimum inter-pulse delay was used. The influences of the inter-pulse delay between two pulses on the LIBS signal intensity, electron temperature and density were investigated. It is most remarkable that the evolutions of signal enhancement and electron temperature versus the inter-pulse delay showed the same behavior and revealed two main regimes of interaction. These results provide additional insight into the possible emission enhancement mechanisms in the double pulse configuration. Source

The pipe thread forming machine was innovatively designed in the article, using Pro/E as a design tool, we built the structural model of the pipe thread forming machine and performed interference detection and movement simulation for it, on the basis of this, we made a physical prototype. And our experiment showed the complete machine has the characteristics of high efficiency, tight structure, small volume and light weight, and it was easy to move. © (2013) Trans Tech Publications, Switzerland.
