seals in the aerospace vehicle plays a very key role the united states quot columbia quot space shuttle crash is the problem caused by seals far industrial equipment co ltd ningbo letter can take the national space research projects the department lin general manager of the company in the field of graphite status 04 16 jiangbei district a business welcomed six countries experts from the department of space the purpose of their visit is to develop these companies for final identification of the seals after a series of tests the six aerospace experts agree that the performance of this material has reached aerospace vehicles as a standard seal this means that our future aerospace vehicles required for manufacturing sealing materials can be imported from the united states is no longer required graphite the most common is the pencil lead it consists of carbon and a great expansion can expand to 280 to 330 times quot expanded graphite through the various formulations and molecular composition can play a more features such as strong resistance to corrosion very good hot stability and creep resistance it can soak in sulfuric acid nitric acid the can withstand 300 degree heat and low temperature 200 degrees below zero is a natural sealing materials quot lin said several years ago graduated from beijing university of aeronautics and astronautics in the lin will be in place of graphite cutting edge research in the field his production of expanded graphite sealing materials and related products not only china 39 s exports account for 70 of the total exports and the product quality has reached the leading domestic 2008 10 months the chinese academy of sciences shaanxi coal rank the go between the state department of space to find lin lin can hope to conduct further research on the graphite and finally developed for the sealing material in the spacecraft to lin was technology and space experts know from the developed application to aerospace vehicle is a big difference between seals however contrary to experts expected that after six months yuan will get new seals developed the national space department may 2009 the new product by the department of state space identification after the first technology the national department of space also proposed to design a more stringent sealing requirements yesterday after rigorous testing at every level yuan once again come up with new products successfully identified yuan told the author that in addition to aerospace applications this expanded graphite was also applied to the nuclear power plant recently he received the first orders for nuclear power plants the original with further research yuan yi lin 39 s research team also found that the graphite has good radiation resistance in fact the graphite of the quot beauty quot is being opened little by little yuan yi lin now this substance are also beginning to enter the lives of ordinary people yuan yi lin said graphite also has excellent thermal conductivity it can quickly transfer the heat out people are using 3g mobile phones plasma tv china needs to have this kind of material at present the famous manufacturer of display products boe also found yuan yi lin the two sides will work together cooperation development of large screen tv

Support our videos at IndieGoGo! www.indiegogo.com Johann Pachelbel’s beautiful interweaving of melody & harmony–one of the great works of music! Soundtrack at tinyurl.com Performed on original instruments by San Francisco Early Music Ensemble Voices of Music. Featuring Katherine Kyme, Carla Moore & Cynthia Freivogel, baroque violin; Tanya Tomkins, baroque cello, Hanneke van Proosdij, baroque organ; David Tayler, theorbo. About the performance: the canon is played using not only the instruments but also the bowing techniques from the time of Pachelbel. As you can see from the video, especially if you look at the high definition version, the string instruments are not only baroque, but they are in baroque setup: this means that the strings, fingerboard, bridge and other parts of the violin appear just as they did in Pachelbel’s time. No metal hardware such as chinrests, clamps or fine tuners are used on the violins, allowing the violins to vibrate freely. A good example of baroque bowing can be seen in the extended passage of repeated notes: the musicians play these notes on one bow—the shorter & lighter baroque bow—to created a gliding effect. The players also hold the bow very differently which affects the balance and touch. Both the style and the amount of vibrato are based on baroque treatises which describe the methods for playing, bowing & articulation in the late 17th century. The narrow, shimmering vibrato blends with the baroque organ. The organ used is made …
