Objective:To investigate the influences of different OD value and centrifugal parameters on the ultrastructure of Escherichia coli in order to find out the best OD value,speed and time of centrifugation.Methods:According to orthogonal experimental designing principle,the E.coli with different OD600 values are divided into 9 different groups of centrifuge speed and time.The changes of E.coli morphology in each group at different OD600 value,centrifuge time and speed were compared under transmission electron microscope.Results:The different OD600 values and centrifugal parameters have little influence on the ultrastructure of E.coli,but when the OD600 value at 0.8,centrifuge time at 15 min,the cross-section ratio was significantly higher than other groups and was more suitable for observation.Conclusion:The best parameter to prepare the TEM samples of E.coli is under the OD600 value at 0.8 and centrifugation time at 8 minutes and speed at 5 000～12 000 r/min.

This paper introduces general guidelines for designing and constructing a magnetic stimulator (MS). These guidelines cover the theoretical concepts, hardware aspects and necessary components. RLC model producing the impulses in MS is focused on and the way to calculate the parameters of the model is presented. Some factors that influence induced magnetic field are discussed. Experiments are carried through with self-developed round coil and 8-shaped, and Tesla meter is used to detect the magnetic fields. The experiments data show that the distribution of the induced magnetic fields by the two coils are tailored to those of theoretical calculation adopted now. A simulation experiment to measure magnetic field in brain has been completed.
