Corrosion sensors are made up of representative condenser tubes chosen by eddy current test, which enable the monitoring result to be consistent with the corrosion of actual condenser tubes. Localized corrosion rate of condenser tubes can be measured indirectly by a galvanic couple made up of tube segments with and without pits. Using this technology, corrosion problems can be found in time and accurately, and anticorrosive measures be made more economic and effective. Applications in two power plants showed the corrosion measurements are fast and accurate.展开更多

Brinell hardness of die-cast AZ91D alloy increases through on-line solution and off-line aging treatment but decreases after off-line solution treatment. By X-ray diffractometry, optical microscopy, differential thermal analysis, scanning electron microscopy and X-ray energy dispersive spectroscopy, it is found that the microstructures of the die-cast AZ91D magnesium alloy before and after on-line solution and off-line aging are similar, consisting of α-Mg and β-Al12Mg17. The precipitation of Al element is prevented by on-line solution so that the effect of solid solution strengthening is enhanced. The β-Al12Mg17 phases precipitate from supersaturated Mg solid solution after off-line aging treatment, and lead to microstructure refinement of AZ91D alloy, so the effect of precipitation hardening is enhanced. The β-Al12Mg17 phases dissolve in the substructure after off-line solution treatment, which leads to that the grain boundary strengthening phase is reduced significantly and the hardness of die cast AZ91D is reduced.展开更多

Agritourism was believed as the optimal carrier of expanding functions of modern agriculture combining agriculture, ecology and tourism industry. From such perspectives, causes for the loss of tourist functions in the development of agricultural demonstration zone were identified as 5 aspects, specifically including various planners from diverse fields; no any technical standard for the planning, or systematic planning theory and technique; many individual planning cases with poor applicability; no innovative idea brought into the tourism project planning; the loss of cultures in new tourist products. After proposing key points in the expansion planning of tourist functions, this research pointed out 4 countermeasures, i.e. (1) design concepts should be changed; (2) planning functions should be reoriented to match service facility planning with laws of tourism development and properly design tourist projects; (3) landscaping planning should be focused on; and (4) eco-environment protection and brand building should be enhanced.展开更多

Furthermore, in accordance with ecology, silviculture, agriculture and economics, the ecological landscapes were classified as per landscape functions; lands returning from farming were classified and re-used; ecosystems of grassland, river, agriculture and courtyard were researched; the feasibility of ecological restoration and sustainable development in demonstration site was demonstrated; the model for rational irrigation and water conservation was proposed. The research guarantees sustainable development of agriculture and animal husbandry and provides references for undeveloped countries with similar problems.展开更多
