First draw vertical header text on the left, then draw uneven background border, then draw a box in the border, and draw three borders with different shapes in the blank. Next, color the header text first, and then color the background red to complement the color of the characters. Continue to draw each border with a different color. Finally, draw a text bar on the border with white embellishment on the background. Can draw a simple handwritten newspaper.
Brief introduction of famous scientists in China
1, Qian Xuesen
19 1 1 year 1 1 was born in Lin 'an County, Hangzhou City, Zhejiang Province in February. He is an outstanding patriotic scientist in China, the third-generation flag bearer in the field of aviation and aerodynamics, the founder of engineering cybernetics, and a figure in the field of applied mathematics and applied mechanics in the 20th century. /kloc-0 was admitted to department of mechanical engineering Railway Gate of Jiaotong University in September, 1929, and/kloc-0 was admitted to Aviation Department of Massachusetts Institute of Technology in September, 1935.
1September, 936, he transferred to the Aviation Department of California Institute of Technology, became a student of the world-famous aerodynamics professor von Carmen, and soon became von Carmen's most proud disciple. He received a master's degree in aviation engineering and a doctorate in aviation mathematics.
From July 1938 to August 1955, Qian Xuesen worked in the fields of aerodynamics, solid mechanics, rockets and missiles in the United States, completed the research project of high-speed aerodynamics with his tutor, and established the "Carmen-Qian approximation" formula. At the age of 28, he became a world-famous aerodynamicist. He died in Beijing at 8: 06 am on June 365438+1October 3 1 2009. I found the relevant documents of 15 for you.
2. Zhang Heng
Ping Zi, a native of Xi, Nanyang (now Shiqiao, Nanyang City, Henan Province), was a great astronomer, mathematician, inventor, geographer, cartographer, writer and scholar in the Eastern Han Dynasty, and made indelible contributions to the development of astronomy, mechanical technology and seismology in China. Because of his outstanding contribution, the United Nations Astronomical Organization once named the asteroid 1802 in the solar system "Zhang Hengxing".
Zhang Heng is one of the representatives of Huntian theory in the middle of Eastern Han Dynasty. He pointed out that the moon itself does not shine, and moonlight is actually a reflection of the sun's light. He also correctly explained the cause of the solar eclipse and realized the relationship between the infinity of the universe and the speed of planetary motion and the distance from the earth.
Zhang Heng observed and recorded 2,500 stars, created the world's first light-leaking armillary sphere, the first instrument for testing earthquakes-the seismograph for waiting for the wind, and also made a south guide car, an automatic drum car, a wooden bird flying to Wan Li and so on.
