The moderate supersonic carbon added to the mold flux for ultra - low carbon steel is used to stay the melting speed as skeleton. then the mold flux coils have the good adiabatic, insulation and even flow property. at the same time it cause the carbon increase in the steel slabs and the operation of the ultra - low carbon is affected at last
超低碳鋼連鑄結晶器用保護渣中，外加中超碳黑作為骨架降低熔化速度，使保護渣具有良好的絕熱保溫性、均勻流動的潤滑性，但同時卻會引起鋼鑄坯的碳增量，最終影響超低碳鋼的成功操作。 -
The flowfield over low - drag and long - range projectile with small attack angle is numerically studied from transonic to supersonic velocity. it provides basic work for aerodynamics characteristic of this projectile and for lateral jet interaction flowfield, and it shows this projectile can decrease drag. zonal method is tried to compute flow over projectiles and results is satisfied, but computation is much slower
系統研究了低阻遠程彈丸在小攻角狀態，低跨聲速、高跨聲速和超聲速時的非對稱繞流流場，為該彈形氣動力研究提供理論指導並為彈丸側噴流研究奠定基礎，結果顯示低阻遠程彈丸外形具有優化繞流場、減小空氣阻力的特點。
