weight concentration
1.The surviving time upon heat exposure and the swimming time were examined and the physiologic and biochemical changes such as body weight, potassium concentration, blood sugar, hemoglobin were compared before and after heat exposure.
2.The results showed that the optimal conditions for theconversion were the initial cell concentration 0.32 g/mL(wet weight), the initial COBE concentration 20 g/L, pH 7.0 and the temperature30℃.
3.Synthesis of HEC-AM graft copolymer initiated by (NH_4)_2S_2O_8-Na_2SO_3. The effect of the different concentration of HEC and others factors on molecular weight of HEC-AM graft polymer was discussed. The results show that the effect on molecular weight of graft polymer as follow, the concentration of HEC is greater than concentration of initial reagent and than the initial temperature.
4.Asignificant positive phenotypic correlation was observed between bodyweight,dressed weight and abdominal fat weight (rp=0.56,0.57,respectively),and selecting for low plasma VLDL concentration wouldreduce body weight indirectly.
5.The growth rate, fresh weight and diy weight of shoots, roots and whole plants could be increased by the increase of K4 concentration.
6.The molecular weight and molecular weight distribution of polyacrylonitrile obtained in supercritical CO2 were measured by GPC method. And the effects of monomer concentration, initiator concentration, reaction time and pressure on the molecular weights, molecular weight distributions and yields were studied in detail.
7.CONCENTRATION RANGE SELECTION IN THE MOLECULAR WEIGHT DETERMINATION BY LOW ANGLE LASER LIGHT SCATTERING METHOD
8.Half of every group rabbits were killed respectively at the end of 8,12 weeks to detect blood glucose value(BG),kidney weight/body weight ratio(KW/BW),urine retinol-binding protein(RBP),N-Acetyl-β-D-Glucosaminidase(NAG) concentration.
9.The number of ear and ripe rate and the weight of thousand ear of rice were increased with the Cu2+ stress in a given concentration range.
10.The dry cell weight of broth reaches 115g/L～160g/L and the maximum rHSA concentration is 3.6g/L at the 120th hour at the fed batch fermentation phase.
