the 2 minutes group is significantly higher (64.41%vs21.15% ,P<0.01) than the 5 minutes group in the ES20 pre-treatment, the result of the 30%EG pre-treatment is contrary(23.64% Vs 57.41%,P<0.01).
The results showed that the pre-treatment time was 0.5-1.0 hour and the recovery rate was 70%-120%,the relative standard deviation was 0.2%-11.4%. The method could meet the need of pesticide residue analysis.
The results showed that R~2 of the functions were respectively 0.8,0.9+,0.99 if no data pre-processing,scalping methods or Lowess were conducted respectively.
The present results indicate that heat stress pretreatment can improve the spatial learning and memorizing function through protection to hippocampal neurons.
The flowering frequency can be further increased to 82.8 % on the average by pre-treatment of protocorms in an ABA-containing medium followed by transfer onto MS medium with BA.
A sample pre-treatment with a column filled with mixed cation-exchange resin in Ag, Ba and H forms was needed before pre-concentration of bromate on alumina.
The optimal temperature programs are defined according to the pre-treatment and atomization curves constructed in the presence of different types of wines.
In centralized multisensor tracking systems, there are out-of-sequence measurements (OOSMs) frequently arising due to different time delays in communication links and varying pre-processing times at the sensor.
