This article describes the importance of energy saving in dyeing and printing fields, as well as heat exchanger applied to open width washing machine, hot air drying and baking machine, steam ager and setting machine.
When Rhodopseudomonas NA 08609 was immobilized in an ager, the immobilized Cell produced hydroen when the suitable initial cell density of 1.5—2.0%(w/v) of agar and Ca 3.0mg(dry)/g gel was adopted. Culture medium "gB" for hydrogen production evacuation is unnecessary.
Rhodopsudomonas NA 08609固定在琼脂中,当固定化琼脂浓度为1.5～2.0%,初始菌体密度为3.0mg蛋白质/g凝胶时对产氢是适宜的。
There were no obvious defferences between the four age-groups at positive rate of MP、ADV、RSV but the positive in the groups of preschool ager children and infant is obviously higher than that in the group of the school-ager childien during the dectection of MP+ADV+RSV in comporision with sexs the diference between boys positive rate and girls positive rate is obvious (P<0.05).
