1. Cook over a fairly high heat until the outsides are browned.

2. Fans inside and around the outsides of the crater are closely similar to Earth's alluvial fans.

3. In practice, it turned out that it was better to overcompensate for the inward yaw on outsides, to add a bit of outward yaw to improve line tension.

4. The present invention relates to a prefabricated hybrid girder composed of precast concrete blocks and steel blocks used as an upper structure of a bridge, and more specifically, to a prefabricated hybrid girder in which two precast concrete blocks are arranged on the outsides thereof, a center block for connecting the same is formed with the steel block, and a gap difference is formed between contact surfaces of connective parts between the blocks to automatically apply prestress force using the gap difference when the blocks are assembled.
