ultrafiltration technique造句

• This method was also effective for concentrating virus form large volume water samples . moreover / the concertration multiple of cyanophage pp could rise to nearly one - hundred times when two - step backflushing ultrafiltration technique was adopted
  此法也适用于大量水样的处理，而且当采用两步反冲超滤技术时，噬藻体的浓缩倍数可以提升到近100倍。
• A new concentration system , the backflushing ultrafiltration system , was constructed with the isolated cyanophage pp in our lab associated with the ultrafiltration technique . basing on this system , the cyanophage concentration multiple could reach up to 30 times and the recovery rate of the cyanophage could exceed 90 %
  浓缩是研究噬藻体的重要前期工作，我们以本实验室分离的淡水噬藻体pp为实验材料，结合超滤技术，建立了一套能够有效浓缩水样中噬藻体的方法- - -反冲超滤法。此浓缩技术可使噬藻体的回收率达90以上，浓缩倍数达30倍。
