It is a none-igniting substitute of the ciga-rette, it has some characteristics with the tradi-tional cigarettes, such ad making you refresh, fulfilling the smokers'needs; But it has much more different with the traditional cigarettes substantially, such as no tar, no ignition, no 460 kinds of chemical substances that can lead to respiratory and cardiac system diseases, no the carcinogenic in the traditional cigarettes. Since the using of tobacco of the history of human, people started to know the know the bad effects of tobacco to the health of human, WHO has gotten through THE FRAMEWORK CONVENTION ON TOBACCO CONTROL(FCTC)(on 21 may 2003),it called on every country should take into account that the threats of tobacco to the health of the health of people. As a result, the technology of getting rid of tar and finding a substitute of cigarette has been developed. In the last few years, because of the technological barriers and microelectronic immaturity, scientists can not develop the product that can approach the taste and flavor of cig-arette. Although German, U.S, Japan had been detel-oped some substitutes of cigars, the uncertain conceptions and coarse technology destroyed the market of the substitutes. Everyone should remember this year.2003, a team that consisted of Chinese scien-tists bread through many difficult and invented RUYAN ANI that has nearly same flavor and taste but has no tisk as traditional cigars. RUYAN ANI, a probuct that applied microelectronic control technology and supercrit-ical atomizing method, can be inhaled by smokers without tar. So the smokers who use l avoid tar and many dangerous substances to get into their lungs and bodies.
