controlled experiment
1.However, his sample was small on both trials -- just 63 people for the controlled telephone experiment and 50 for the email -- and only four subjects were actually filmed in the phone study and five in the email, prompting some scepticism.
2.A controlled hydroponics experiment was conducted to investigate the effects of three NH4+ / NO3- ratios (0/ 100, 50/50 and 100/0) on the photosynthesis and the key nitrogen metabolism enzymes of three wheat cultivars with different sensitivity to enhanced ammonium nutrition (EAN).
3.QTM controlled atmosphere drying experiment equipment was used to regulate the O 2 content in the drying by displacing part air with nitrogen as drying medium.
4.Study of Bifurcation and Chaos in the Current-Mode Controlled Buck-Boost DC-DC Converter (Ⅱ)——Numerical Analysis and Experiment
5.The reliability and stability of the results can be ensured by adding the analysis module of reliability and stability in the multidisciplinary design optimization flow, and the design variables can be controlled by using DOE (design of experiment) method and 6a method to guarantee the stable convergence in the design process.
8.To testify the hypothesis, this paper undertakes an experiment carried out in two classes of random samples- the 63 students in the environmental chemistry class as the controlled group (CG) and the 61 students in the computer class as the experiment group (EG).
9.THE EXPERIMENT OF OBSERVING ELECTRICALLY ELECTRICALLY CONTROLLED BIREFRINGENCE (ECB)OF LIQUID CRYSTAL WITH POLARIZING MICROSCOPE
10.It was suitable that 500 mg/L Cef and 5 mg/L Kan used acted as concentration of controlled the propagation of Ag and level of selection in the regeneration experiment of transformation in apple, that 500 mg/L Cef and 5 mg/L Kan used selected resistant shoots in the subsequent rooting experiment.
