略乾燥的
英文
subarid-
In view of the present situation, in this paper, a new moisture analyzer which combines infrared drying oven and electronic balance is proposed takes dsp as the information processing unit. it presents the instrument structure and the hardware design of the system. it actualizes the temperature real time control in the drying equipment through controlling the power of the heater element and taking an complex control method
針對這一現狀,本文提出了一種將紅外乾燥箱和電子天平相結合,利用dsp作為信息處理單元的水分測定儀;給出了儀器結構和dsp系統的硬體電路設計;研究通過對加熱元件的功率控制實現乾燥箱的溫度控制,採用智能復合控制策略對乾燥箱的溫度進行實時控制,乾燥箱的溫度達到105的時間可由單純pid控制的2分鐘減少到1分鐘,且控制精度高。After the acet is vaporized, the active substance in water is gotten. and which is vaporized at low temperature. then the crude active substance is purified by column chromatography on sephadex g - 75. after a series of purifications again, we could get some white powder at last. though the active substance is diluted to50 g / ml, the activity is still checkeded - up through phyto phtnora casicileon. the purified active substance is insensitive to heat, resistant to chloroform 、 ethanol and the orhers. in addition, the active substance is sensitive to high ph ( 10 ~ 14 ), but it is not sensitive to low ph ( 1 ~ 5 ). furthermre, when the ph is made to low again, the activity of it ' s comes back
用蒸餾水對菌體稀釋;加入適量吸附樹脂在150rpm 、 28下振蕩吸附4h , 80 %的丙酮解吸,過濾解吸液得到活性物質的澄清溶液,旋轉蒸發儀旋轉蒸發去處丙酮,經sephadexg - 75分子篩層析得單一活性峰,收集峰值部分樣品液經冷凍乾燥得到淡褐色粉末,該活性物質用丙酮充分洗滌、甲醇-乙醚重結晶獲得略帶微黃的白色粉末,該活性物質50 g / ml仍可對蘇雲金芽孢桿菌hd - 1產生明顯的抑制作用。The results indicate that drying thickness, radiant temperature and pressure of drying chamber are the most three significant factors. there ' s hardly any relationship between freezing rate and drying time, the sublimation drying time of slow freezing material is shorter than quick freezing one, but its desorption drying time is relatively longer, so the total drying time is approximately the same. the initial freezing temperature and freezing manner has little influence on vacuum freeze drying process
試驗表明:凍干厚度、加熱板溫度、系統的真空度是最重要的三個過程參數;凍結速率對總凍干時間沒有影響,慢凍物料的升華乾燥時間要比快凍物料短,但慢凍的解析時間相對較長,兩者的總凍干時間相差很小;初始凍結溫度對凍干過程的影響可以忽略。Dry skin to manage the itchiness due to dry skin, the most important is to apply moisturizing cream frequently, especially after bathing when the skin is still moist
乾燥-避免因皮膚乾燥而造成痕癢,最重要是使用潤膚膏來保持皮膚滋潤,次數不限,尤其不可忽略的時間是沐浴后,在皮膚仍然濕潤時。Research and discussion on fuzzy control strategies involved in grain drying process
穀物乾燥過程模糊控制策略的研究與探討Hot - spray granulating is usually applied to heat - sensitive materials and ensures no quality - change problems whatsoever, omitting regular complicated processes such as concentrating, filtering, grinding, grading, and drying
因此噴霧造粒技術應用於對熱敏感的材料也鮮少有變質情形,而且可以省略濃縮、過濾、粉碎、分級、乾燥等繁瑣工程。分享友人
