  4. There are many ways of modulating signal about bpsk such as castas loop, square loop, etc. usually the carrier wave is put forward firstly, then the purified carrier wave is used to demodulate the output data ( all these things are usually completed in the same loop ). these methods have their strong points but at same times, it is difficult to design and achieve these ways

    有關bpsk調制信號的解調方法很多,例如castas環,平方環等,這些方法一般都是先提取載波,然後用提純的載波去解調出傳輸的數據(大都在同一個環路內完成) ,這些方法的優點是顯而易見的,但是在某些條件下,這些方法的設計和實現卻很困難。
  5. The expressed product was lysised with supersonic wave and purified by sds - page. elisa analysis revealed that the antigenicity of the vpi protein has been detected. the forth part - detection of aev - nh937 strain by in situ hybridization ( 1sh ) - probe was labelled with digoxigenin ( dig ). then the probe hybrid with 5d, 10d, and 20d postinfection brain tissue of chicken. the results of the ish showed that the positive signal was found in 3 cases, while control group was negative. there has been a reasonable correlatien between this method and other detection test
