查询词典 high-melting metal

Methods The contents of ferromagnetic elements and other metal elements in lagenal otoliths of adult homing pigeons were precisely analyzed with inductively coupled plasma mass spectrometry of high sensitivity, and then they were compared with those in saccular and utricular otoliths (all the contents were normalized to Ca).

应用具有高灵敏度和稳定性的电感耦合等离子体质谱法测定成年信鸽瓶状囊耳石样品中磁性元素Fe、Co、Ni以及其它金属元素的含量(以Ca含量作为基准的百分比含量)并同内耳的球囊和椭圆囊耳石中的这些元素的含量进行比较。

The contents of metal elements Zn, Ba and Cu in lagenal otoliths were lower than those in saccular otoliths. Conclusion The contents of magnetic elements in lagenal otoliths of homing pigeons are not much higher than those in utricular and saccular otoliths, which does not support the hypothesis that birds depend on high contents of Fe and Zn in lagenal otoliths for sensation of geomagnetic information.

结果表明成年信鸽瓶状囊耳石中磁性元素的含量极低而且不比内耳球囊和椭圆囊耳石更丰富，从而不支持信鸽因其瓶状囊耳石中含有较高的Fe、Zn等元素而能够感受地球磁场这一假说。

Panzhihua-Xichang area in Sichuan is abundant in vanadic titianomagnetite deposit. Because vanadium and titanium are transition metals and the difference between their atomic numbers is only 1, titanium carbide and vanadium carbide are refractory, high hardness and thermodynamically stable metal carbides.

而采用粉末冶金原位合成法不但可以解决铸造法因增强相体积分数增加及增强相与铁基体的密度差异而导致的铸造缺陷以及SHS的致密化问题，而且克服了粉末冶金法存在的增强体与基体之间结合不良的问题。

Aluminum is an abundant and cheap non-ferrous metal. As a new-fashioned fuel cell, the aluminum/air battery has been attaching importance, due to its low-cost, high power and energy density.

铝是一种丰富廉价的有色金属，铝-空气电池作为一种新型燃料电池，由于有低成本、无毒害、高功率、高能量密度等优点，受到了极大重视。

The research trends and development on high temperature creep of metal matrix composites in China are presented.

针对目前我国金属基复合材料的抗高温蠕变性能的研究方法提出了一些看法和展望。

Kim Sung-Tatsu metal forging company specializing in the production of a variety of hand tools, the current main production of various steel picks, octagonal hammers, crowbars and a variety of group sets of tools in high-quality hardware tools.

金成达五金锻压公司专业生产各种手动工具，当前主要生产各种钢镐头、八角锤、撬棍及各种组套工具等中高品质五金工具。

What's more, the begavior of the metals at excessively high temperature also differs from that at normal temperatures and can produce a condition in which the metal deforms slowly and continuously at a constant stress.

另外，在过高的温度下金属的反应也不同于正常温度，过高的温度会引起金属的缓慢变形和金属承受持续的恒定压力。

When they are bonded together and heated, the metal with the high expansion rate elongates much more than the other strip.

当他们粘结在一起，加热，金属与高膨胀率鱼远远超过其他地带。

&依利达ELIDA&牌自动打包机/捆扎机：1、接头短，不用铁扣，符合国际环保要求又节约成本；2、打包速度快，效率高，每打一道PP带仅需1.5秒；3、速热系统，1V低电压，安全性好，瞬间加热，开机5秒钟后进入最佳打包状态；4、自动停机装置，省电实用。

The most probable cause of the erosion is the too high speed of the fluid with the entrained metal particles.

最可能的原因就是过高的流体速度，而且流体中还夹带有金属颗粒。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
