酒精沸点温度较低,易挥发,提高酒精回收得率是关键。
除此之外,一些农药,比如氨基甲酸盐剂,不耐热并因此难以在不分解的情况下挥发。
罗森说:“我们认为,稻米中有这种酶就会挥发砷,生产出的稻米砷的含量自然就会少。”
在35℃加热并搅拌,使溶剂挥发,制得大小均一、尺寸单分散的聚酯微球。
1·"We propose that rice expressing the enzyme will volatilize arsenic, producing rice grains with reduced arsenic content," Rosen says.
罗森说:“我们认为,稻米中有这种酶就会挥发砷,生产出的稻米砷的含量自然就会少。”
2·Alcohol will volatilize after exposure to the air.
酒精暴露在空气中会挥发。
3·As more and more chemical construction materials and equipment that volatilize harmful matter are being used in construction, the indoor air pollution is becoming more serious.
随着大量能够挥发出有害物质的化工建材和设备在建筑中的使用,室内空气污染日益严重。
4·Resisting the balance backset current boiling point the ones that reduce and brake oil volatilize effectively.
搞平衡回流沸点,有效减少刹车油的挥发。
5·Resisting the balance backset current boiling point , the ones that reduce and brake oil volatilize effectively.
