2.The ARAM-ARIES wired telemetric seismograph based on Windows-NT operational system has advantages of bulk capacity storage,field data processing,automatic checking,ordered data transferring,file automatic formation,by-offset providing. It is beneficial to 3D seismic prospecting,and especially convenient for operating parameter determination,head amplifier gain selecting,arrangement and layout.
3.The development of the squash fruit come to a head 7-14 days later after being pollinated, while its seed has two development acme period, one is 7～14 days after pollination which is embryonic-form-built time to decide the bulk of seed production, the other is 21～28 days after pollination which is its embryo-plenum-development period and is the crucial time to decide the quality of seed production.
