您要查找的是不是：
- FXD does not have any free carbon in the preheat flame and does not blow back in the torch. FXD的预热火焰没有自由碳，不能进行黑色金属之间的焊接。
- FXD will not weld mild steel to steel because of the absence of free carbon in the preheat flame. || 因为缺少自由碳，FXD将不能进行火焰加热的钢与钢的焊接。
- The reaction bonding SiC ceramic whose density is 3.16 g/cm3 apparently has advantage over the one whose density is 3.07 g/cm3.The one who has less free carbon shows stronger resistance to chemical corrosion then others when they are of the same density. 密度为3.;16 g/cm3的反应烧结SiC耐化学腐蚀性能显著优于密度为3
- The results showed that, adding P into BN Mg system can obtain crystals without free carbon, while adding LiH and NH 4Cl into Li 3N BN system can obtain CBN crystals of high strength and high thermal stability. 研究表明 ,结晶介质成分和合成参数一样 ,对立方氮化硼结晶的完整性 ,杂质成分对晶体特性的影响起着重要的作用 ,指出 ,往BN -Mg体系中 ,引入P可培育出不含游离硼的晶体 ,而往Li3N -BN体系中引入LiH和NH4 Cl时 ,所得到的立方氮化硼具有高的强度和热稳定性。
- The SEM studies shows that P[NR/HAF-Dy(OH)_3] vulcanizate shows superior mechanical properties that depend primarily on the absence of free carbon black,the fine dispersion of carbon black in the rubber matrix and better polymer-filler interaction. SEM分析表明,HAF-Dy(OH)3以团粒形态存在于NR基体中,团粒表面覆盖一层NR膜,团粒与NR构成的界面模糊,说明HAF-Dy(OH)3与NR基体结合紧密,这是P[NR/HAF-Dy(OH)3]具有较好物理机械性能的主要原因。
