The Theorem of the Resistance of Hydraulic Machine's Materials to Cavitation Erosion and Abrasion

Wang Biao,Wang Yudong,Zhang Zihua,Ye Xianguo

Strategic Study of CAE 2003, Volume 5, Issue 7,   Pages 58-61

Abstract:

In order to confirm the dependence of the resistance of cavitation erosion and abrasion (CEA) on the common properties of materials, four typical materials (WC coating, NiCr alloy coating, boron stainless steel and titanium) were used to do the experiments of CEA and cavitation erosion (CE), to do corrosive experiment, and to test their hardnesses. The experiments results indicated that all resistance to CEA and resistance to CE depend on the hardness and the corrosive resistance of materials. The high hardness is the first factor of good resistance to CEA, strong corrosive resistance is the second factor. Meanwhile, the strong corrosive resistance is the first factor of good resistance to CE, high hardness is the second factor.

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 2,   Pages 284-292 doi: 10.1007/s11783-013-0555-7

Abstract: The goal of this work was to investigate particle associated PAHs sampling artifacts caused by ozoneComparative sampling systems were operated simultaneously during the whole campaign, one with activatedcarbon ozone denuder, the other being set as conventional sampling system.Ambient temperature was founded to have influences on PAHs sampling artifacts.High temperature can increase loss of particle associated PAHs during sampling.

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 6,   Pages 449-456 doi: 10.1631/FITEE.1400377

Abstract: When evaluating the accessibility of a large website, we rely on sampling methods to reduce the costTo improve sampling quality, stratified sampling methods first cluster web pages in a site and then drawIn existing stratified sampling methods, however, all the pages in a website need to be analyzed forTo address this issue, we propose a novel page sampling method based on URL clustering for web accessibilityUsing only the URL information for stratified page sampling, URLSamp can efficiently scale to large websites
