Lubricating features of combination of Sulfurized Olefin (T321 ) and Phosphorous-Nitrogen (P-N ) agents were determined by HQ- 1 machine. A synergistic effect between T321 and P-N agents has been found. PN- 2 and T321 combined together has the best lubricating property.
A four-ball machine was used to evaluate the extreme pressure and antiwear (EP&AW) properties of molybdenum dialkyldithiophosphate (MoDDP) in 150N paraffinic base oil and two formulated oils, SJ15W/40 and SH15W/40, and its antiwear synergistic effect with zinc dialkyldithiophosphate (ZnDDP) was investigated. Besides, the antiwar action mechanism was analyzed.
The resistance to Ca2 + and Mg2 + of HABS combined with alkanolamide, the synergism of HABS with petroleum carboxylate, and the stability and oil - recovery efficiency of ASP(alkali, surfactant, polymer) system based on HABS were investigated.
The research was carried out on synergetic effect of cationic Gemini surfactants and conventional surfactants mixture reducing oil and water interfacial tension by use of Uniform Design, and the results indicated that there exhibited obvious synergetic effect for non-ion conventional surfactant, OP-10, and Gemini surfactant, GS14-2-14, during the course of mixture reducing oil /water IFT, and Uniform Design method can be used in the area of chemical flooding and compound chemical flooding.
The experiments prove that this noninic-anionic ampholytic surfactant can improve salt tolerance of petroleum sulfonate, and the super low interfacial tension can be obtained without addition of low molecule weight alcohol due to the interfacial tension synergetic effect.
Result\ Temperature oscillation in thermal production may cause lithology change, solution, and wettability change, which, on the contrary, will act with other formation damage factors and produce synergism effect and bring on worse damage.
Depending on the ratio of the biocides, the active concentrations needed to maintain the synergistic effect can be decreased 4- to 20-fold.
Auxin and anti-gibberellin (retardant) activities produced a synergistic effect.
The synergistic effect underlay a significant increase in the amount and quality of the crop (e.g., tomatoes).
The obtained data suggest that the synergistic effect on the common cockroaches and houseflies is chiefly due to carboxylesterase inhibition by monothioderivatives and monooxygenase suppression by dithioderivatives, respectively.
Dimegin and HP had no effect on the activation of guanylate cyclase by YC-1; they did not change the synergistic effect of YC-1 (3 μM) and sodium nitroprusside (10 μM) on guanylate cyclase activity.
A synergetic effect of the component mixture was observed in determining total metals.
The synergetic effect of iridium(IV) and rhodium(III) on the rate of the indicator reaction was estimated; the range of catalyst ratios for the simultaneous determination of analytes was determined.
A synergetic effect has been detected since ZrO2 and Y2O3 exhibit significantly lower activities than the mixed oxides.
We noted the synergetic effect of ECD and IAA on coleoptile elongation, the antagonistic effect of ECD and EBL on coleoptile elongation, as well as the antagonistic action of ECD and GA3 on coleoptile elongation and α-amylase activity.
The distribution ratio increases from 200 to 1200 as the DOS concentration rises from 0 to 0.25 mol/L (positive synergetic effect).
These results indicate that the coprecipitation process for synthesizing CoTi-substituted barium M-type ferrite ultrafine powders is simultaneously influenced by synergetic coprecipation effect of cations and coordination effect of Cl- anions.
The coordination effect on the Clpy modes is analyzed.
It is demonstrated that the acid and coordination effect of the ligand play the same important role in the Na2WO4·2H2O catalyzed oxidation of cyclohexene to adipic acid with 30% hydrogen peroxide.
This finding is not consistent with a metal-coordination effect, but is in keeping with the greater polarity of pyridine than piperidine.
This coordination effect of information provision is the focus of this section.
