induced precipitation
3.EP-RED is complete iron control system for oil well acidizing. This product uses field proven technology to minimize iron induced sludge and precipitation problems in all types of acidizing.
4.Hydrogen absorption,hydrogen-induced amorphization(HIA),precipitation of RH_2 and crystallization of an amorphous phase occurred with increasing temperature for R=Y,Sm,Gd,Tb,Dy and Ho.
5.The effects of concentrations of LiClCv3H2O and the foreign water added in ACN on the EQCI responses were individually examined, and the maximum frequency shift induced by the LiOH precipitation was found to be as large as about -5 kHz.
6.the light acid precipitation induced sugar accumulation in the roots and stems, but the strong acid precipitation inhibited it;
7.The mechanism of precipitation of copper in multicrystalline silicon (mc-Si) and Czochraski silicon (Cz -Si) under different thermal treatment was investigated by means of Electron Beam Induced Current (EBIC) in this paper.
8.Based on an analysis of dynamic conditions for migration and precipitation of gold grains in water system and their diffusion in soil, this paper has advanced a discriminant formula for surfacce ore potential of gold anomalies from 1:50000 stream sediment survey, recounted methods for estimating the highest gold grade ores within the anomalies, calculated the discriminant indices for Qinba area, and summed up index characteristics of ore-induced gold anomalies in 1:10000 soil survey, estimation formulae for orebody location as well as coefficients and constants of slope angles of various orders and grades.
