The application of 100 mm steel balls and 80 mm balls in a ratio of 1∶1 instead of 125 mm balls can not only intensify the selective grinding with the selective liberation as the core so that the single mineral liberation degree is greatly improved,but can also improve the particle size characteristics of the ground product and greatly raise the mill capacity.
The piezoelectric properties, Curie temperature and high temperature resistivity of CaBi4Ti4O15 are greatly improved through small size cation doping and additional vacancy in A-site, and an excellent high-temperature lead-free piezoelectric material with tc=866℃, d33=20 pC/N is obtained.
After incorporation of Ni(Ⅱ), the electrode (poly-Ni(Ⅱ) Try/GC) was greatly improved in catalytic activity. The potential 0.65 V of methanol oxidation at the poly-Ni(Ⅱ)Try/GC is much more negative than the potential at the poly-Try/GC and at the bare glassy carbon (GC) electrode in 0.01 mol/L NaOH.

In this paper,the compactness of ZQSn10-2 alloy has been investigated by adding alloy element of Bismuth,the results show that adequate Bismuth can greatly improve the oil pressure resistance of ZQSn10-2 alloy.
The purity of molten steel could be improved greatly af ter treatment with VD, what′s more,≤2×10 -6 ,≤15×10 -6 , ≤50×10 -6 ,the cortent of impurity could be deduced greatly,the qualif ied rate of flaw detection to steel plate could be improved greatly;
The products of CaAl_2O_4∶Eu~(2+) were prepared by high temperature solid state reaction, traditional precipitation method and precipitation method using ultrasonic radiation, respectively. The result shows that the product obtained by ultrasonic-precipitation (method) cannot form agglomeration and the particles size is 70 nm,and the relative luminescent (intensity) was improved greatly.
Field experimental results show that the might of three pulse laser radar has been improved greatly, the smallest detectable SNR is 1.5, and the head-on intercept and capture distance can be improved about 2~3 times.
When reacted for 8h at 0.08mol/L Pb2+,ΔA/A0 for the two substrates became 2.29 and 0.49 times of the original values, respectively, indicating a greatly increased stability of the inclusion complex to the variation of the metal cation concentration and the temperature relative to the Oneothera Biennis oil.
The ability of particle swarm optimization (PSO) algorithm to break away from the local optimum is greatly improved by the mutation.
The accuracy of invariants in phase space reconstruction is greatly improved.
Contrary to what has been reported for Escherichia coli, the expression of vgb in E.aerogenes decreased several fold under 10% of atmospheric oxygen (≈2% oxygen) and its growth was not greatly improved by the presence of VHb.
The resistance to localized corrosion of aluminum alloys such as Al 2024, Al 6061 and Al 7075 has been greatly improved by immersion in hot cerium salt solutions.
(ii) Nuclear maturation is greatly improved by prolonging IVM duration from 36 to 42 h, while no significant differences were observed for developmental potential of transgenic embryos.
During the inductive treatment, the phloem transport of cytokinins was enhanced and their content in the shoot apex greatly increased for some time.
At the same time, the ratio of labeled sucrose to labeled hexoses decreased, and the incorporation of the label into serine greatly increased.
A method is proposed for resolving experimentally the details of the resonant fluorescence spectrum of a Bose condensate within a homogeneous line whose width is greatly increased because of collective effects.
The topicality of income difference and poverty issues has greatly increased in post-Soviet Russia.
The magnitude of signal attenuation at the resonance point was greatly increased by the integration up to -30 and -57 dB for the 1-μm-thick and 2-μm-thick CoNbZr films, respectively.
