however, either coal conversion or acetylene yield grew downwards as the feedstock rate was increased.
随着煤比能耗的增加,煤的转化率和乙炔收率呈增加趋势;
acetylene and oxygen cylinders must be kept outside the confine space. supply hoses must be disconnected from cylinder when stop for any break.
乙炔和氧气瓶不应放置在封闭空间内。在乙炔和氧气瓶暂停供气时,应将供气软管与瓶体断开。
the test solution was injected into air acetylene flame to determine calcium and magnesium by standard addition method.
将试液喷入空气-乙炔火焰,用标準加入法测定,测定结果与灰化法一致。
results show that the addition reaction of bromine with acetylene was obviously influenced by light condition.
研究表明,光线条件对溴素与乙炔加成反应过程有非常明显的影响。
similarly, non-biological chemical reactions could transform acetylene into benzene – a hydrocarbon that the vims instrument did observe on titan「s surface.
相似地,非生物的化学反应会把乙炔变成笨—一种vims在「提坦」表面上发现的碳氢化合物。
oxygen is widely applied in the metal ndustries in conjunction with acetylene and other fuel gas es for metal cutting welding scarfing hardening cleaning and melting.
同乙炔和其它燃料气体一起,氧广泛应用于金属工业的金属切割,焊接,嵌接,淬火,清洁和熔化。
therefore, high-quality selection of acetylene it is particularly important.
因此,优质乙炔的选用就显得尤为重要。
in addition, in case of emergency can be acetylene torch on the pull down hose.
此外,在紧急情况下可将焊炬上的乙炔胶管拔下来。
federal law prohibits persons, other than cylinder manufacturers, from repairing acetylene cylinders. disposal of unserviceable cylinders should only be attempted by experienced personnel.
联邦法律禁止任何人,除了钢瓶制造商以外,修理乙炔钢瓶。只能由有经验的人来处理废弃钢瓶。
allene is an isomer of methyl acetylene .
丙二烯是甲基乙炔的一种异构体。
sharp dents in the cylinder can break up the filler in the area of the dent and cause voids where free acetylene can accumulate and decompose at cylinder pressures.
钢瓶内尖锐的凹陷会扎破凹陷附近的填充物,产生空隙。自由乙炔会积聚在在空隙处,并在钢瓶压力下分解。
this would result in a lack of acetylene on titan and a depletion of hydrogen close to the moon」s surface, where the microbes would live, they said.
他们说:这可能造成「提坦」卫星上乙炔的缺失和靠近卫星表面氢的耗尽,那里是微生物生活之处。
nucleobases can assemble spontaneously, in a series of steps, from cyanide, acetylene and water—simple molecules that were certainly present in the primordial mix of chemicals.
经由一连串的步骤,堿基能由氰化物、乙炔与水自动形成,这些简单分子必定存在地球初始的化合物中;
in a corner of the café, an acetylene lamp gives a flickering light.
一盏电石灯在咖啡馆的角落里闪烁不定。
it is because that the particle size of acetylene black is smaller than that of graphite , it is easy to disperse well among active material.
这是因为乙炔黑的粒度比石墨小,比表面积相对更大,能很好地分散在活性物质之间。
