In order to provide theoritical foundation for the utilization of jerusalem artichoke ( ja ) resource, culturation of bifidobacteria and development of bifidobacteria products. this paper rather systernly studied the effects of ja on the growth of bifidobacteria, using jerusalem artichoke juice ( jaj ) and jerusalem artichoke powder ( jap ) as experimental material. in the first place, the effects of ja on the growth of bifidobacteria in vitro were studied. the results indicated that : jaj could stimulated the growth of b. longum ( blm ) and b. bifidwn ( bbm ) ; the more jaj content was added, the more promoting action was apparent ; the promoting action also varied from the different species. adding jap ( 3 % ) to skim milk could decrease the time of milk - solidfying of blm and bbm, and could increase the acid production in skim milk of the strains tested. secondly, bifidobacterium medium was developed using jaj as main material
本文以菊芋汁和菊芋粉為主要材料，較系統地研究了菊芋對雙歧桿菌生長的影響，以期為進一步開發利用菊芋資源、雙歧桿菌的培養及其製品開發提供理論依據。菊芋在體外對雙歧桿菌生長的影響試驗表明，菊芋汁在體外對長雙歧桿菌（ blm ）和兩歧雙歧桿菌（ bbm ）的生長具有促進作用，其效果隨著菊芋汁添加量的增加而增加，並且對不同菌種的促生長效果存在差異；在脫脂乳中添加3的菊芋粉可以縮短blm和bbm的凝乳時間，其原因可能為促進了試驗雙歧桿菌在脫脂乳中的產酸。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。Frp light pole, in its service life, will not get rusty, not easy to be scrapped and no need to be painted. its weather - resistance is bettor than that of wood, aluminum, steel and cement ones
Frp燈桿不生銹，在整個使用壽命期間，無需保養，不易刮破，不用上漆，耐氣候性較木材、鋁、鋼、混凝土要好。Abstract : techniques of apple genetic transformation can improve apple trees and shorten the breeding cycle by molecular methods. in the last years, great progress has been made in this field, which involves a number of important apple genotypes developed. so far, apple genetic ransformation mainly adopts agrobacterium - mediated technique, involving infection and transgenic tissue regeneration, which are important steps to affect the transformation efficiency. the initial work to the date is to know and to search for the factors which can increase the efficiency
摘要蘋果的遺傳轉化技術通過分子手段改良蘋果，有助於縮短其育種周期.最近十年，在該領域的研究取得很大進展，涉及到一些重要的蘋果基因型及有用的外源基因.迄今，蘋果的遺傳轉化主要採用農桿菌介導法，侵染與轉化材料的再生是影響其轉化效率的關鍵過程，了解其影響因素，尋找有利因素以提高轉化效率是目前蘋果遺傳轉化研究的重點。Based on calculation method on unfold size and piece form, theory analysis and research are given on ellipse, circle tube, box as equal - high, irregular, unequal - high, irregular piece, process and condition on possibility of drawing are introduced, through calculation coefficient, number of drawing, drawing testing dies are made, results are given, it is similar to calculation method, in the same time, complex drawing presswork is planed, to avoid wrinkle, critical in drawing process. in this paper, die designing is introduced based on complex drawing unfold size calculation, press center is automatic calculated, apartments of press tools are calculated too with material mechanic production process and press form are better, period of die designing is to reduced, and cost of product is lower
對基於復雜拉深件展開尺寸計算的模具設計也作了詳細的論述，指出了現有復雜拉深件模具設計製造程序的不合理性，本文在復雜拉深件展開尺寸基礎上自動生成沖裁中心、沖裁周長，運用材料力學中桿件強度及抗失穩條件，實現對沖壓模具參數的自動計算，簡化了沖壓模具彈性元件、打料裝置的設計過程，給出了沖壓模具結構設計流程，使得模具材料核算，製造過程，沖壓方式更趨合理，縮短了模具設計製造周期，降低了產品生產成本。Meanwhile, it does not need a extra time to be carried out. it can continuously work during the excavation of trenches, so whole work cycle can be reduced. anchors and layers of shot concrete have replaced the traditional steel frames and piles, including concrete piles, steel piles, and they can largely economize construction materials, such as steel and concrete, reduce the amount of soil that would be excavated out, and improve work conditions
錨桿施工機械及設備作業空間小，可為各種地形及場地使用，同時，它不獨占工期，而隨基坑開挖同步、流水進行，節約工期;用錨桿及噴射硅面層代替傳統的鋼支撐和樁（硅樁、鋼板樁） ，能夠大量節省鋼材、硅等建材，減少土方開挖量且能改善施工條件;其次錨桿的預加應力可以通過抗拔實驗來獲得。The techniques of cast - in - situ concrete box girder by movable formwork bridging machine, which is a railway erection crane for bridge made up by universal rods, are effective, reliable and can use the exiting road for opporation
