First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.

Using cytochalasin D to prevent global actin from forming filamentous structures, the production of Heliothis armigera nuclear polyhedrosis virus in Hz-AM1 cells grown in the medium containing 0.5μg/ml CD was completely inhibited while its production was reduced to 10〓 in the presence of 0.1μg/ml CD by plaque assay. However, Western blotting revealed that the actin quantity in infected host cells treated or untreated with CD was almost identical. Additionally, CD had no effect on the DNA synthesis of HaNPV.
