Nanjing, June 4 (Mr. Somerset) The year of the Venus, which is worth looking forward to in 2012, will be staged on June 6th. On the 3rd, Wang Sichao, a researcher at the Purple Mountain Observatory of the Chinese Academy of Sciences, introduced that the transit of Venus in the world is frequent. The ground is visible, and the next time you see it again you will need to wait until 2117.
According to Wang Sichao, a researcher at the Purple Mountain Observatory of the Chinese Academy of Sciences, the Lingyue can be visited in Europe (except southwest polar regions), eastern Africa, Asia, Indian Ocean, Oceania, Pacific Ocean, Arctic Ocean, North America, northwestern South America, and northwest Atlantic. see. From the "Ling Shi" to the "Ling End" process in central and eastern China, from the 6:09:41 time on the 6th Beijing time, "Ling Shi" (Venus just came into contact with the sun) to 12:49:31 "Last End" (Venus completely out of the sun), the entire process will continue for more than 6 hours. In the western part of China, the sun can be seen radiating.
The so-called transit of Venus means that Venus runs between the sun and the earth, and the three are in a straight line. If the weather is fine, then the public will see a "small black dragonfly" slowly across the sun's face.
The rules for the emergence of "Venus transit day" are generally divided into two groups: 8 years, 121.5 years, 8 years and 105 years. Generally speaking, there are only four occurrences every 243 years or so.
Wang Shichao reminded that it is necessary to pay attention to the protection of the eyes to use filters, and must not wear ordinary sunglasses to observe directly, so as to avoid permanent damage to the eyes. (Finish)

Shaping Machine
Shaping machine is a machine designed for giving desired shapes to the surfaces that may be horizontal, vertical and flat. A shaping tool is used to cut in curves, different angles, and many other shapes. A disc is responsible for the tool rotation which results in the forward and backward movement. The cutting tool is used to give the shape to the hard surface of metal or wood by removing the excess material.
The shaping machine operates in the reciprocating type of machine function. Here the work piece is fixed on the machine table and the cutting tool is placed on the work piece. Reciprocating movements over the work piece results in forward and backward strokes. Forward stroke is responsible for cutting action over the object and backward movement is responsible for restoring its position without any cutting action.
