The result shows that the best extraction condition is at 80℃,time 8 hours,adding water 30 times,and the efficiency is 1.72%,quantity of protein 5.44%.
D>A>B>C(A: decocting time, B: decocting frequency, C: adding water volume, D: alcohol concentration). The opti-mizing preparation conditions were A_2B_2C_1D_2, i. e. added 10 times water, decoction for twice, 1.5 h every time. The precipitating concentration of alcohol was 50%.
According to the research into the technology of the composite beverage of lily, asparagus, aloe, it shows that the most suitable processing of the thick liquid of lily juice is adding Vc of 0.2% and citric acid of 0.1% to the thick liquids when it is being beat as the preprocessing. afterwards polishing the thick liquid and adding water amount as 1∶2, the appropriate result is obtaining solidity as 1% of the crystal thick liquid.
Viscosity reduction rate of heavy oil(705 Pa·s, 50℃) is up to 97% under the optimistic conditions in which the concentration of catalyst is 0.2%, the ratio of added water, 20%, the reaction temperature 280℃ and the reaction time 36 hours.

The optimizing preparation conditions were A3B3C1D1, i.e. added 10 times water, decoction for 3 times, 0.5 hour every time and added alcohol to 40%.
The new extraction method of hemin was reported in d et ails. The yield and purity achieved 90% and 96%, respectively, in the conditions of 20% added water, 10 min ultrasonic hemolysis and 15 min extraction .
The standard enthalpies of formation of I and II and their crystal hydrates from uranium trioxide, sulfonic acids, and water and enthalpies of water addition to anhydrous salts and lower hydrates of II were calculated.
Reaction of 2-(3-hydroxy-3-methyl-1-butynyl)adamantan-2-ol with acetonitrile under Ritter reaction conditions is accompanied by isomerization and partial hydration where the water addition to the triple bond occurs nonselectively.
The chemical shift (δH) decreases as the amount of water added to the system increases due to the differences in contribution of these three states of water in the samples.
The oxygen-deficient perovskites containing coordination-unsaturated metalatoms can reconstruct their coordination polyhedron by adding water molecules, with subsequent partial dissociation of water to hydroxyl groups.
This effect depends on the interval between the times of preparation of a C60/NMP solution and its dilution with water: the size of the clusters formed as a result of adding water increases with increasing the age of the initial solution.
Adding water vapor to the He-air mixture increases the spectral range of the UV source toward shortwave region, which is related to a spontaneous decay of the products of dissociation of water molecules.
After purification by washing the silica gel with acid and base and after deactivation of the dried silica gel by adding water (5%) the isomerization processes could be avoided.
In this work we have investigated the short-(>amp;lt;2 min) and long-term (up to 48 h) effect of adding water to acetone and methanol extracts from two marine phytoplankton species,Emiliania hyxleyi andDunaliella tertiolecta.
However, the cyst does not behave ideally in the sense that the densities of the nonaqueous components and added water are not additive as a function ofWf.
The apparent density, which decreases as the amount of added water increases, reaches a critical value where the structural collapse occurs independently of the foaming temperature.
