An alloy for the manufacture of cast components, for example taps, water meters, pipe couplings and parts thereof, intended for use in potable water supply installations comprises 1.5 to 7 wt % bismuth, from 5 to 15 wt % zinc, from 1 to 12 wt % tin, the balance apart from any ...
The data base most resembling the subsystems and applications found in the water distribution system was developed by Shultz and Parr (1981) in a study of wastewater treatment plants conducted for the U.S. Environmental Protection Agency. Unfortunately, Shultz and Parr did not collect data on two...
but also the air temperature prior to an oil spill are important for the distribution of water soluble oil components: A relatively high air temperature leads to a more porous ice, and the major part of the water soluble components (WSC) will leak out quickly and the toxicity in the ice ...
The water-soluble pentosans had the highest water adsorption capacity. The theoretical distribution of water between the flour components (calculated using the Guggenheim-Anderson-de Boer parameters) was starch, 88%; gluten, 10%; and pentosans, 2%. 展开 关键词: wordswater adsorption isotherms, ...

metallogenic system/ Liangshan molybdenum deposit 钦杭成矿带(江西段)为环西太平洋成矿带的组成部分,区内地层出露齐全,是我国重要的金属产地。良山钼矿床位于赣中新余市,属于武功山—铅山成矿亚区带西部。新余良山钼矿床近地表主要发育石英脉型钼矿石,多见于细脉浸染状、薄膜状。良山钼矿是在良山铁矿床中产出的有...
Chapter 10 was concerned with the various types of electronic subunits that make up a system. These subunits are themselves made up of a number of electronic components connected together to form electrical current paths called a circuit . A diagram showing how the components are connected is call...
Water samples were collected from the mainstream and distributaries of the middle and lower reaches of the Chishui River Basin in the withered water period to analyze the hydrochemical components.The results showed that the main basic cation was Ca2+,which accounts for above 64% of the total ba...
To avoid high concentrations of lead in potable water lead pipes and lead containing parts within the water distribution system have to be removed.Moreover,lead can be released into surface-and groundwater from several substances,e.g.pesticides,fuel additives,and special paints.There is also an ...
Large-scale control systems tend to present a large number of alternative and back-up elements that, although not used in nominal operation, could be brought into play if necessary. Such hardware redundancy extends the fault tolerant capabilities of the system, while posing the problem of selecting...
