查询词典 speculum metal

Arboreal plant Paulownia fortunei, Ulmus pumila and Broussonetia papyrifera had relatively higher complex ability to accumulate heavy metal.Cedrus deodara, Platanus acerifolia and Ligustrum lucidum also had some complex ability to accumulate heavy metal. These species could be selected as the greenery tree as well as purified tree in the area. Among the herbaceous plants, the accumulation ability of Cynodon dacytlon was better than others.

经对比筛选，木本植物中泡桐、白榆和构树具有较高的重金属综合富集能力，雪松、悬铃木和女贞等树种亦有一定的富集能力，这些树种可被选为该区净化重金属污染的绿化树种；草本植物中，狗牙根的富集能力大大超过其他草本植物。

在分析中，综述了电催化高级氧化电极研究现状，阐述与评价了过渡金属涂层电极、金属氧化物涂层电极、含掺杂半导体涂层电极、金刚石膜电极、三维电极等几个主要方面的研究成果，并对今后工作的重点提出了一些意见。

They used a process called atomic layer deposition, which not only coated spider dragline silks with metal but also caused some metal ions to penetrate the fibers and react with their protein structure.

他们用到了一种称之为原子级别表面沉积方法。这个方法不但将蜘蛛牵引丝上覆盖了金属，而且会使得一些金属离子渗入纤维和其蛋白质解构起反应。

Since it is fairly common for the machining dimensions of the metal labyrinth type sealing device being over the tolerances,it is suggested that more attention should be paid to the inspection on key dimensions of the metal labyrinth type axlebox,dust guard ring,long axle box front cover and the end sleeve,so as to prevent hot box accident caused by friction between matched parts.

针对目前金属迷宫式密封装置机械加工尺寸超差较为普遍的现象，提出对金属迷宫式轴箱、防尘挡圈、长轴轴箱前盖及顶套的关键尺寸应加强检测，以防止配合件发生摩擦造成燃轴事故。

Metals on the absorption of laser light energy to the metal actually inside the transmission, once the incident laser photon to metal crystals, photon elastic collision with electrons, photons transfer their energy to the electronics, from the low-energy level of electronic transitions to the high-energy level.

金属对激光的吸收实际上也是光能向金属内的传输，一旦激光光子入射到金属晶体，光子就与电子发生弹性碰撞，光子将其能量传递给电子，使电子由原来的低能级跃迁到高能级。
