EnglishChinese
After repeated field experiments, they drew a conclusion that as the charge increases, the fragmentation and the velocity of the broken material increases as well经过多次实地测试、他们的结论是、如果药量的增加、破碎量和飞石的速度也随之剧增
All emissions with the potential to cause environmental impacts are quantified along the entire life cycle from raw material extraction through to final disposal所有对环境造成影响的排放、从原料开采一直到最后的处理的整个生产周期、都要予以量化
An advanced society consists of material,spiritual and environmental civilizations先进的社会是由物质文明、精神文明和环境文明构成的
As the expanding gases compress such material, energy is lost rapidly and pressure and temperature drop sharply in the reaction products. These losses are communicated to the interior of the reaction zone as a rarefaction wave, lowering the pressure and reaction rate, and ultimately removing support far the propagation of the detonation front由于膨胀气体挤压这种物质、致使能量损失速度快、爆后产物的压力和温度迅速下降。这些损失作为膨胀波传到反应区之内、因而降低了压力和反应速率、且最终消除了对爆震波面传播的能量支持
basic stemming material or solution碱性炮泥或溶液
Blast gases can vent up along the blasthole to launch stemming material and/ or fragments from the collar region爆破产生的气体会沿着炮孔将孔口周边的堵塞物和/或碎块抛出
China Explosive Material Trade Association中国爆破器材行业协会
choke material of hole炮孔填塞材料
In confined blasting, however, the borehole in which the explosive material is placed is capped with material such as crushed rock然而在约束爆破中、装了炸药的炮孔覆盖了诸如破碎岩石那样的炮泥
material props材料参数
material shear modulus材料剪切模量
micro-material evidence微量物证
minor material evidence微量物证
raw material extraction原料开采
R-occurs when stemming material is inefficient or insufficient. Rifling is driven by the stemming release pulse SRP for airblast炮泥不足时会出现螺纹线。由于空气冲击波、螺纹线是由炮泥释放脉冲形成的
simulating material modeling of rock engineering岩体工程相似材料模拟岩石力学模拟方法之一。岩体工程相似材料模拟实验的理论基础是相似原理, 若两个系统相似，则表征该两系统的对应物理量成一定比例关系，表述各对应物理量之关系的数学表达式也相同。在工程岩石力学模拟研究中，相似条件应包括几何相似、运动相似和动力相似
Some consideration is given to the stemming length but no consideration is given to the stemming material and particle size of the rock人们虽然考虑到炮泥长度,但没考虑到炮孔填塞材料和岩石粒度
The rate of chemical reaction is strongly pressure dependent and will decrease rapidly as the reacting material expands化学反应速率取决于压力的大小、并随着反应物质的膨胀而迅速降低
The type and adequacy of the stemming material used and the management of progressive relief during detonation have a strong influence on the amount of material thrown into the air and hence the proportion of dust likely to be emit ted from a blast爆破中所用的炮泥类型和分量以及对阶梯地形的处理、会大大地影响抛向空中的物质的多寡、因此也大大地影响一次爆破中可能喷出的飞尘比例
This material is recognized as being likely to become airborne and farm an aerosol хим. and considered to be capable of being inhaled by humans, penetrating the gas exchange region of the lungs人们注意到、这种物质很可能悬浮在空中、称为悬浮微粒。并认为这种物质可由人呼进肺腑、穿透肺部的气体交换区
This material remains available to be released to the atmosphere whenever the muckpile is disturbed by excavation, transport or subsequent handling一旦爆堆受到开挖、'运输或后续处理时扰动、这种物质就随时会释放到大气之中
trace material evidence微量物证
Upstream raw material supply and ammonium nitrate manufacture are considered, together with the end-use of explosives on mine sites上游原材料供应和硝酸铵生产、以及炸药在矿区的最终用途、是考虑的内容
water-material ratio水砂比一定体积的砂浆中,水与充填材料体积之比
