Often lack of fusion adjacent to the girder web in the transverse groove welds led to the cracking . 在靠近主梁腹板的横向坡口焊缝处常常出现未熔透而导致裂纹。
Hence lack of fusion and slag would exist at the weld root and create a large initial crack condition . 因而未熔透及夹渣存在于焊缝棍部，并造成大的初始裂纹条件。
The large thermal mass of the melt generally precludes any short-term control of the process according to temperature . 大的热熔体通常较难按温度实现过程的短期控制。
Into the new work she was going to pour all her thoughts and feelings, her vital life episodes, her bitter sweet experiences . 她要把自己一生几个重要时期的经历和感受都熔入笔端倾泻在新作中。
It is not possible to make this light alloy by melting the small part of copper and then adding the much larger part of aluminium . 在炼这种轻质合金时，就不能先熔小部分的铜，再加进大部分铝。
the phase diagram of the - system is complicated, and eutectic hydrates such as - and -2 occur. -体系的相图是复杂的，产生象和2之类的低共熔水合物。
Subsequent redistribution of uranium in provinces formed at that time most probably resulted from orogenic processes and associated anatexis . 铀在成矿区内的重新分布，最可能是由于造山作用及伴随的泾熔作用。
A novel method to reduce crucible erosion is by suppressing thermal convection currents, which can be done by applying a magnetic field to the melt . 减少坩埚侵蚀的有效方法是对熔体施加磁场以抑制热对流的流动。
The film index is higher than that of bulk glass of the same composition as the target, but prepared by rapid quenching from the melt . 薄膜折射率高于与靶成分相同的体型玻璃折射率，而此玻璃是由熔体迅速冷却制得的。
Pyrometers, radiometers, bolometers are used for determining heat radiation and have applications for measuring the surface temperature of hot lavas . 高温计、辐射计、辐射热测量仪用来测定热辐射和热岩熔的表面温度。
