Recently, the chinese plant protection agencies reported the growing hardships in controlling some field populations of oriental migratory locust with organophosphate ( op ) compounds. up to now there are more than 600 arthropod species with documented resistance to one or more insecticides and / or acaricides since resistance phenomenon was first described in san jose scale to lime - sulfur in washington in 1908. enhanced metabolic detoxification and reduced sensitivity of insecticide target - sites are the two major mechanisms in resistance development, involving three primary metabolic enzymes of esterases, glutathione s - transferases and cytochrome p450 polysubstrate monooxygenases
代謝抗性是指對殺蟲劑起水解或隔離作用的酶發生改變，從而對殺蟲劑起到解毒作用，昆蟲主要解毒酶系有酯酶、谷胱甘肽- s -轉移酶、細胞色素p450單加氧酶等，這三種酶系任何一種的組成部分發生改變均會引起害蟲抗性的改變；靶標抗性是指由於殺蟲劑作用靶標敏感度降低而產生的抗性。Since the middle of 20th century chinese scientists have put considerable effort and resources into the search for new antimalarial compounds extracted from chinese traditional herbs. an antimalarial drug was finally isolated in 1971 and named artemisinin or qinghaosu. its rapid action, low toxicity and powerful effect against falciparum malaria made it a favored subject for research

摘要評述了對甲苯磺酸、強酸性陽離子交換樹脂、磺化聚氯乙烯樹脂、六水三氯化鐵、聚氯乙烯三氯化鐵樹脂、氯化聚氯乙烯三氯化鐵樹脂、二水氯化亞錫、十二水合硫酸鐵按、硫酸鐵硫代硫酸鉀復鹽、四水硫酸鈰、一水硫酸氫鈉、硫酸氫鉀、三氧化二釹、固體超強酸和雜多酸等催化劑催化合成氯乙酸乙酯的實驗結果。The polyester fibre of resisting bacterium is one without which people can t live in modern times, but how to restrain the bacterium propagating excessively and keep people in health is a most important goal that fabrics and clothing industry are striving for. fibre of resisting bacterium can kill the bacterium effectively with the ratio of more than 99 % and it can restrain microbes. the polyester fibre of resisting ultraviolet radiation is also widely used. with the decreasing of ozonospheres in the atmosphere, there are more ultraviolet radiation in the sunlight which do harm to our skin, especially for those men working outdoors, it is more important to think about the way to lessen the harm. the polyester of burning - resisting has attracted more attention at home and abroad and burning - resisting textiles has been advanced definitely by law in many countries. our nation has also made strict claims in some special areas, such as fabrics in vehiciles and vessels, decorative fabrics in hotels. the everlasting burning - resisting fibres and textiles are badly needed. infrared ray fibre is also a new functional one that can absorb and reflect infrared ray after being processed physically. it s functions include physical therapy wet - ejecting and bacterium - restraining. this warm - preserving material can absorb the emitting heat from our bodies, at the same time it can also absorb and reflect the needed 4 - 14 urn wavelength ultraviolet radiation and accelerate netaboiism. fibre of resisting infrared ray is important in military areas
抗菌纖維具有永久的抗菌性，對金黃色葡萄球菌、大腸桿菌殺菌率大於99 ，能有效抑制細菌繁殖，起到抗菌防臭作用；抗紫外線聚酯纖維的用途也是異常廣泛的，隨著大氣層中臭氧層的日漸稀薄，日光中的紫外線日益增加，對人體皮膚形成極大危害，尤其對于長期從事野外工作的人，因此設法減少紫外線對人體的傷害顯得尤為重要；阻燃聚酯纖維則是一種倍受國內外人士密切關注的纖維，紡織品阻燃在許多國家已有明確法令規定，我國也逐漸在某些特殊使用范圍做嚴格要求，如車船內用紡織品，高級賓館的內裝飾織物等，而且具持久性阻燃性的纖維和織物是現在更為需要的，真可謂用途非常廣泛；遠紅外纖維也是一種經過物理改性后具有吸收並反射遠紅外線的新型功能性纖維，是一種具有優良理療功能、熱效應功能和排濕透氣抑菌功能的新型紡織材料及保溫材料，能吸收人體自身向外散發的熱量，吸收並反射回人體最需要的4 14 m波長的遠紅外線，促進人體的新陳代謝；抗紅外線纖維，則在軍事上有著重要的作用。The main research now is focused on the polymerization of difluoramino substituted oxetane monomers, the preparation of neopentyl difluoramino nitrato plasticizers, and the molecular design and synthesis of cyclic n - nitramino geminal difluoramino oxidizers
目前該領域的研究工作主要集中在二氟氨基取代環氧丁烷聚合物合成，新戊基二氟氨基硝酸酯增塑劑制備，以及環n -硝胺基偕二氟氨基氧化劑的分子設計與合成上。Unicolor and lilium asiatic hybrids or cultivars in lilium asiatic hybrids were researched with their parents by karyotype, soluble protein, esterase isoenzyme and peroxidase isoenzyme. the results provided identification markers of cytology and biochemistry for hybridization at the early stage in lily breeding programs. the cluster analysis according to similarity coefficient of soluble protein and peroxidase showed that " yellow " and " omega " have the most closest relation in lilium asiatic hybrids
