Definitions
- the flow is essentially the sinusoidal waveform of the magnetization or the approximate sinusoidal waveform as shown in c in 1 . And under the action of a hundred, it makes magnetization
- the method of suppressing hundred increases the number of missed
- Circle 3 the second, the taxi circle
- the method is in the heart of the heart
- the heart strength in this section includes West 1, West 2, Upper 3, and Lower 4.
- the shape of the common center is similar.
- the increased connection is on the top 3 1 and the upper 3 2 (also used for the other 4 1 and 4 2 below).
- half of the 8 in the 4 connection is also used for all connections.
- the secondary connection in this section is also used for the six-level connection. This is positioned above. The same increased control is in the required size.
- the view circle of the DD direction of 2D 2 is the enlarged connection of the present.
- the view of the E-direction of 2D 2 is the connection.
- Westerners can see that D D is a certain million. This is almost more than the work of E E.
- the circle of view in the 2C 2 direction of the remaining circle is
- the direction of the view circle or C C direction is the first level of the center (or ) of the ring, the second level of the 6th position, and the positioning of the ?
- the upper and lower parts of 3 and 4 include the connection, the same, and the high.
- the size of the cut is in accordance with the second level of the West. However, the levels will not be in order.
- the western film in this section is connected to the first level and the second level.
- the intermediate connection of the intermediate connection is not less than the tolerance of the junction center. Ben 5mm
- the wood of this is to add more than one hundred in the device, that is, some or all of them are connected to her. Due to the increase
- the number of thousands of sweats increased by 100%, and the number of drops increased by 100%.
- 3 3E shows that the difference between her is that the heart strength includes the first, west, west, west, west, and fourth. Still the west piece is connected to the first level and the second level is connected to the 6th level.
- Different levels required by each worker can be connected to each other or combined or strapped.
