查询词典 magnetic field

By analyzing numerically the disks around a young stellar object and a black hole, we can obtain: the dissipation can not be neglected as a magnetic field is in small threshold value; in Keplerian disks, the magnetic field is smaller, the dissipation caused by anomalous viscosity and anomalous resistivity deviates from the ideal more greatly; the dissipative effects on magnetic instability become smaller as the radius r becomes larger.

The isolated cells are able to orient and migrate to the magnet in artificial magnetic field but could not orient swimming only under the geomagnetic field. Magnetosomes produced by Acidithiobacillus ferrooxidans were range from 40nm to 90 nm according to the results of TEM. Energy dispersive X-ray analysis indicated that extracted magnetic particles consisted of oxygen and iron. The results show that some Acidithiobacillus ferrooxidans cells have weak magnetotaxis and they could be able to be separated by solid-plate magnetophoresis method from others. With the development of this new isolation method, it is possible that we could do deeper research to generate a comprehensive description of the mechanism that how Acidithiobacillus ferrooxidans synthesize the magnetic particles.
