查询词典 hybrid

PDC bit crown profile, consisting of single circular arc parabola profile or dual cone profile with deeper inner taper is introduced. Cutter arrangement for various bits is determined. The bit is improved by the application of hybrid cutting structure and detailed analysis of hydraulic structure. Simultaneously, bit stability is enhanced using multiple bit stable structure design techniques such as deep inner taper, force balance and hybrid cutter arrangement etc.

Laboratory experiments were carried out to study the survival and development of the Harmonia axyridis feeding on Chaito phorus popleti on high insect-resisitance hybrid poplar 741(Pb29) and medium insect-resisitance hybrid poplar 741(Pbl7).The API 741 poplar was used as control.The mortality and development during immature period,adult,baby mass.eclosion and sex ratio of H. axyridis were measured.The results showed that:to contrast The API 741, Chaito phorus popleti on Pbl7 and Pb29 has no significantly impacts on eclosion,pupation, ecdysis,mortality of immature period and pupa stage;Although every development stage of ladybeetles were not affected to ,the pupal duration of ladybeetles was lowered than the control;The body mass,eclosion and sex ratio have no significant difference.
