The second part , a renewable piezoelectric immunosensor is developed for the antibody of schistosoma - japonicum ( sjab ) . after incubating 32 kd molecular antigens of schistosoma japonicum ( sjag ) on the qcm by applying the immobilization above , the nonspecific sites on the immunosensor are sealed by using bsa and nrs together . the immunosensor can detect the sjab with the linear range of 0 . 54 ~ 32 . 50 ug / ml 以感染兔血清为检测对象，采用聚电解质吸附固定法，将日本血吸虫分子抗原( siag32kd )固定于石英晶振表面，再以牛血清白蛋白( bsa )和正常兔血清( nrs )联合封闭晶振上非特异性活性位点，可在0 . 54 32 . 50ug ml范围内检测感染兔血清中日本血吸虫抗体。
It is found that this qcm technique is not only to be comparable to the surface plasmon resonance ( spr ) in response characteristics , but also more simple , cheap and reproducible in its equipments . the fourth part , an amplified by peg mass piezoelectric immunoassay has been developed to detect the ceruloplasmin in human serum 将之用于测定了人血清白蛋白（ hsa ）抗体的活性，并与文献报道的表面等离子体子共振法（ spr ）进行了比较，发现该传感系统的响应性能可与spr法媲美，而且较之具有仪器简单廉价、再生简便等优点。
It provides a new thought for modifying and immobilizing mass recognizing film on the surface of qcm sensors when the substance is difficult to deposit or the performance of the membrane is not steady . so the plasma technique can be widely used to make qcm sensors , the qcm sensor is steady , easy to regenesis and has tong lifetime 在“等离子体qcm化学传感器”一章中，详述了另一种重要的化学传感器?三乙醇胺涂膜qcm传感器的传感特性与器件性能，并对处理前后的性能做了对照，等离子体表面改性处理后的三乙醇胺qcm传感器对烷烃类的i性率高o00 ） 。
