The results shown that oxide total was decreased from original amount0.035% to 0.007%,sulfide total from0.029% to 0.01%,roundnessof inclusions was changed from 1.43 to 1.03.It has been found that NbN and Nb2C can be formed in the liquid state of manganese steel because of addition of complex modifier.
The liquid state fermentation conditions of monascus-nata complex were studied. The optimum fermentation conditions were as follows: patato15 %, glucose 5 %, NaNO3 0.2 %, MgSO4 0.1 %, ZnSO4 0.1 %,PH 6.0,cultivated for 13 d at 26 ℃. The content of monacolin k was 152.00 mg/L and color value was 128.38 μ/g dry monascus-nata .
Atmosphere aerosols is a scatter system that solidity or liquidness particles scattered into atmosphere. Though the mass of atmospheric aerosol particles only have a proportion of one billionth of atmospheric mass, it have an important effect to the radiative process, climatic change, environmental, quality, cloud and precipitation process, and process of water circulation that make up the radiative climate effect, environmental health effect, and cloud physics effect.
Pluronic F-127 (Sigma Company, No. P2443) was white power with no odour, and its water solution was liquidness at 4 ℃, and solid gelatum at 37 ℃. ②After the rabbits were anesthetized, the bone marrow was taken from superior extremity of tibia to isolate and culture the MSCs;
A simulation study has been performed for the evolutions of microstructures in a liquid metal Ni sys-tem during solidification process under different cooling rates by means of molecular dynamics method and EAM model potential.
Based on design principles for intermediate heat exchangers of the sodium cooled fast breeder reactor and design requirements of a liquid metal sodium boiling test, a high temperature liquid metal sodium-sodium heat exchanger has been designed on the optimization design principles in association with the comprehensive consideration of heat transfer capability, thermal expansion stress.
Quantitative Structure-Retention Relationships Applied to Reversed-Phase High-Perfromance Liquid Chromatography
A brief summary of the theoretical background of QSRR is followed by presentation of reversed-phase high performance liquid chromatographic (RP-HPLC) separation theories of applications to the reported QSRR.
Two new trichothecenes, Roridin P and Isororidin P, and two known trichothecenes, Verrucarin A and Verrucarin J, were isolated from liquid cultures of Myrothecium roridum Tale ex Fr.
A sensitive high-performance liquid chromatography (HPLC) method was established for the determination of concentration of 5-FU-1-acetic acid in the gastrointestinal contents and plasma of rats.
This article demonstrates the use of a linear programming model to achieve an optimal allocation of liquid funds among various currencies in different countries.
It is found that the temperature coefficient of the SAXS intensity (phonon component) for boron oxide changes at the temperature of the transition from a supercooled liquid state to a solid noncrystalline state.
The change in the slope is associated with the change in the temperature coefficients of the isothermal compressibility upon transition from a liquid state to a supercooled liquid state.
The temperatures of the glass transition and the transition from the supercooled liquid state to the noncrystalline solid state are determined from the temperature dependences of the SAXS intensity.
Changes in volume occurring during transition from the solid to the liquid state are estimated.
For the liquid state, this is unimportant; however, for the solid crystalline state, the situation changes significantly.
