all available means所有能用的手段
An increase in air temperature causes an increase in the speed of sound, which means that in these conditions airblast emissions can be focused back toward the ground by atmospheric refraction大气温度的增高、促使声速增加、这是说在这些条件下、大气折射可将冲击波挡回到地面
arithmetic mean particle diameter算术平均粒径
arithmetic mean value算术平均值
Blasting is a primary means of extracting minerals and ores at surface mining operations爆破是露天采矿作业采掘矿物和矿石的一种主要手段
castover commonly means either total castover the total amount of overburden cast into the previously mined pit, or 2 direct castover the amount of overburden cast into the previously mined pit that is in final location and does not have to be dug by the dragline或2直接抛掷量覆盖层抛掷进人先前采空区最终装载位置不需要吊铲进行挖运的数量
castover commonly means either total castover the total amount of overburden cast into the previously mined pit, or 2 direct castover the amount of overburden cast into the previously mined pit that is in final location and does not have to be dug by the dragline抛掷量通常是指1全部抛掷量覆盖层抛掷进人先前采空区的全部数量
exploitation means勘探手段地质勘探所采用的技术手段。包括地质填图、钻探、坑探、物探、化探、遥感等
harmonic mean谐和平均值
logarithmic mean particle diameter对数平均粒径
mean fragment sizeK50碎块平均尺寸50%质量或体积的碎片物料通过的方形网目尺寸,单位为m
mean grain size平均粒径土中比之小的颗粒含量为总质量50%的粒径(d₅₀)
mean load per unit cycle循环平均阻力一个采煤循环内支架〈支柱〉阻力的时间加权平均值
mean passing size平均过筛粒度
mean reduction ratio平均破碎比
mean square deviation均方差某项试验指标各测定值与其算术平均值之差的平方值的总和除以测定总次数所得的商的平方根
mean square error中误差某项试验指标的均方差与测定总次数平方根的比值
mean velocity测量
means for construction safety施工安全措施为保护施工人员的安全和健康,预防人体受到伤害和财物受到损失,在技术上采用的办法
Modern dynamites can be defined a cap-sensitive mixtures which contain nitroglycerin as a sensitizer or as the principal means for developing energy, and which, when properly initiated, decompose at detonation velocity现代用的硝甘炸药可定义为雷管起爆型混合物。其中所含的硝化甘油敏化剂、或作为拓展能量的主要媒介、若适当起爆、雷管起爆型混合物则在爆轰速度下
prescribed mean and standard deviation预定的平均标准偏移量
resulting mean passing size最终平均筛分粒度
root-mean-square均方根值
The actual make-up of detonation gases emitted on mines cannot be accurately determined and this means that potentially powerful GHGs like CH₄ cannot be quantified with any certainty采矿时喷发的爆炸气体实际成分没法准确定论、这就是说、像甲烷这种有严重潜在危害的温室气体没法准确量化
The augmentation of the volume of an explosive means a rise of the strength of a blast炸药用量的增加意味着爆炸威力的提升
The mean or average firing time for any group of detonators typically is slightly offset from the nominal firing time. This shift of the mean from the nominal is the first timing accuracy factor. The distribution of the firing times around the mean firing time is the second factor一组雷管的平均起爆时间一般稍微偏离标称的起爆时间。这种平均值对公称值的偏移则是第一个影响定时精确的因素。在平均值附近的起爆时间分布是第二个因素
The term airblast overpressure means simply a pressure generated during blasting operations above that of atmospheric pressure that is always present冲击波超压这一术语仅指爆破作业时产生的、且超过无所不在的大气压力的一种压力
This approach to the derivation of rock factors has been used by many field operators in a wide range of blasting and fragmentation studies and has been shown to lead to a reasonable estimate of the required blasting intensity and the resulting mean passing size in a wide range of blasting environments很多实地操作人员把这种求导岩石系数的方法广泛应用于爆破剂破岩研究之中、并证明应用这种方法可以合理地估算所需的爆破强度以及诸多爆破环境下岩石的最终平均过筛粒度
time-weighted mean load density时间加权平均工作阻力
