1. The model loop-line test apparatus(MLTA) has its strongpoint to study the characteristics of the crude oil in pipelines.

2. From the magnetic hysteresis loop-line, we can know some other parameters such as saturated magnetizing strength, magnetic conductivity, etc.

3. This paper introduces some magnetic parameters of magnetic material, such as magnetic hysteresis loop-line, electrical resistivity and magnetoresistivity, and the methods to measure them.

4. The Land lies in the central area of Nankai District, on the north side of Changjiang Dao. Close to the inner loop-line, and No. 1 Subway, it is easily accessible.

5. The experimental study on shutdown and restart characteristics of the gelled crude oil in pipelines is done on the model loop-line test apparatus.

6. It introduces that how to watch and measure the hysteresis loop-line, residual magnet and coercive force of ferromagnet through an oscillograph.
