    在20世紀20年代,美國航空業的陀螺儀制造過程中提出了生產環境的凈化要求。在制造車間、實驗室建立了“控制裝配區”,供給一定量的過濾后的空氣。在朝鮮戰爭中,美國找到了電子儀器出故障的主要原因是灰塵作怪,從而促成了空氣凈化技術的起步。
    In the 1920s, the purification requirements for the production environment were first put forward in the gyroscope manufacturing process of the American aviation industry. A "control assembly area" has been set up in the manufacturing workshop and laboratory to supply a certain amount of filtered air. In the Korean War, the United States found that the main reason for the failure of electronic instruments was the dust, which contributed to the start of air purification technology.
    1957年,前蘇聯顆人造衛星的升空,刺激了美國加速發展宇航事業,制定了阿波羅登月計劃,其電子控制儀器和精密機械加工環境均要求凈化,因而促進了凈化技術的大發展,建造了百級潔凈室,誔生了個潔凈室標準。
    In 1957, the launch of the first Sputnik in the former Soviet Union stimulated the accelerated development of aerospace industry in the United States. The Apollo moon landing program was formulated. The electronic control instruments and precision machining environment required purification, thus promoting the development of purification technology. A hundred level clean room was built, and the first clean room standard was born.
    1970年,1K位的集成電路開始大規模生產,使凈化技術的發展突飛猛進。20世紀80年代,大規模和超大規模集成電路的生產,使空氣凈化技術有了進一步的發展,集成電路的更細光刻線寬達到2~3um。在70年代末和80年代初,美國、日本研制出0.1um級空氣過濾器,為潔凈度的提高創造了條件。
    In 1970, the large-scale production of 1K bit integrated circuit started, which made the development of purification technology rapidly. In the 1980s, the production of large-scale and super large-scale integrated circuits made the air purification technology further developed, and the thinnest optical linewidth of integrated circuits reached 2-3um. In the late 1970s and early 1980s, the United States and Japan developed a 0.1um class high efficiency air filter, which created conditions for the improvement of cleanliness.
    在20世紀90年代,超大規模集成電路的生產有了新的進展,更細光刻線寬由80年代的微米級發展到亞微米級。到20世紀末,要求達到0.1~0.2um,集成度達到1kM。集成電路的集成度越高,要求的光刻線寬就越小,則要求控制的塵粒粒徑就越小,塵粒數量也越少。如今,要求0.1um10級的潔凈度已經很普遍,將來要求的潔凈度會更高,潔凈室的應用領域會更加寬廣。

    In the 1990s, the production of VLSI has made new progress. The narrowest optical linewidth has developed from the micron level in the 1980s to the submicron level. By the end of the 20th century, it is required to reach 0.1-0.2um, and the integration degree is 1km. The higher the integration degree of integrated circuit, the smaller the photolithography linewidth required, the smaller the dust particle size required to be controlled, and the smaller the number of dust particles. Nowadays, it is very common to require 0.1um10 class cleanliness. In the future, the required cleanliness will be higher and the application field of clean room will be wider.
    在2001年中國科協學術年會上,楊振寧教授指出,在今后三四十年,三個領域將成為科技發展的“火車頭”:① 芯片的廣泛應用。 ②醫學與藥物的高速發展。③ 生物工程。芯片需在工業潔凈室中生產,藥品需在生物潔凈室中生產,醫學研究、生物工程都離不開生物潔凈室。對于有生物學危險的操作,需要在生物安全潔凈室中進行。工業潔凈室、生物潔凈室及生物安全潔凈室,都是應用空氣凈化技術創造的特殊的微環境。
    In 2001, Professor Yang Zhenning pointed out that in the next 30 to 40 years, three fields will become the "locomotive" of scientific and Technological Development: ① the wide application of chips. ② The rapid development of medicine and medicine. ③ Bioengineering. Chips need to be produced in the industrial clean room, drugs need to be produced in the biological clean room, medical research and bioengineering are inseparable from the biological clean room. For operations with biological hazards, they need to be carried out in the biosafety clean room. Industrial clean room, biological clean room and biosafety clean room are all special micro environments created by air purification technology.
    電子產業的飛速發展,將推動中國凈化技術向高水平發展,而醫學與藥物的快速發展,必將使空氣凈化技術的應用更加廣泛。中國在制藥行業實施GMP(Good Manufacturing Prac-tice)認證制度以來,生物潔凈室的興建像雨后春筍,給凈化技術產業帶來的繁榮。近年來,三級甲等醫院紛紛建造潔凈手術部,使術后感染率降低10倍以上,從而可以少用或不用抗生素,減輕了抗生素對患者造成的傷害。這也將進一步拓寬凈化技術的應用領域。
    The rapid development of electronic industry will promote the development of China's purification technology to a high level, and the rapid development of medicine and medicine will make the application of air purification technology more extensive. Since the implementation of GMP (good manufacturing prac tice) certification system in the pharmaceutical industry in China, the construction of biological cleanrooms has mushroomed, bringing unprecedented prosperity to the purification technology industry. In recent years, the third class A hospitals have built clean operating departments, which can reduce the postoperative infection rate by more than 10 times, so that antibiotics can be used less or not, reducing the harm of antibiotics to patients. This will further expand the application of purification technology.
    2003年SARS病素肆虐,使人們對空氣傳播病毒的危險性有了深刻的認識。更值得反思的就是醫院建筑,不僅要注重建筑外形與使用功能,更應該關注建筑內的空氣品質。據了解,人吃進1億個兔熱桿菌才感謝染,若吸入10~50個就發熱。這給只重視接觸感染而輕視氣溶膠傳播的呼吸道感染的醫護人員敲響了警鐘。因為氣溶膠傳播更具有爆發性、低感染劑量和大范圍的特點,危險性極大。因此,現代醫院建筑應有空氣凈化設備,才能保證醫患人員的安全。應裝配空氣凈化系統的醫院建筑有:潔凈手術部、生物治療實驗室、傳染病人隔離室、營養液配制、制劑、無菌物品供應等。這將給凈化技術的應用帶來新的機遇。
    In 2003, SARS was rampant, which made people have a deep understanding of the risk of air borne virus. The most worthy reflection is the hospital building, which should not only pay attention to the shape and function of the building, but also the air quality in the building. It is understood that people eat 100 million rabbit thermobacilli to thank for infection, if inhaled 10-50, they will get fever. This is a wake-up call for medical staff who only pay attention to exposure to infection and despise aerosol borne respiratory tract infection. Because aerosol transmission is more explosive, low infection dose and large-scale, it is very dangerous. Therefore, modern hospital buildings should have air purification equipment to ensure the safety of doctors and patients. The hospital buildings that should be equipped with air purification system include: clean operation Department, biological treatment laboratory, isolation room for infectious patients, nutrient solution preparation center, preparation center, sterile supplies center, etc. This will bring new opportunities to the application of purification technology.
    在21世紀,生物工程對人類的直接影響將超過芯片,而其發展離不開空氣凈化技術。如生物工程中有相當一部分操作存在潛在危險性,特別是存在可能具有未知毒性的微生物新種傳播生物學危險。這就需要提供具有生物安全的建筑微環境,可利用空氣凈化技術、生物安全知識來建造生物安全潔凈室來控制這種具有生物學危險的污染的傳播。
    In the 21st century, the direct impact of bioengineering on human beings will exceed that of chips, and its development cannot be separated from air purification technology. For example, in bioengineering, there are potential risks in a considerable part of operations, especially in the transmission of new microbial species with unknown toxicity. Therefore, it is necessary to provide a building micro environment with biosafety. Air purification technology and biosafety knowledge can be used to build biosafety clean rooms to control the spread of this biologically dangerous pollution.
