Yb : look , there are no such huge rocks on this island at all . but where are they from 海尔弟弟:你们快看,这种石头岛上没有。恩,这么大是从哪儿运来的呢!
Several factors in influencing the capabilities of er ~ ( 3 + ) / yb ~ ( 3 + ) co - doped phosphate glass waveguide laser were introduced 其次论述了影响铒镱共掺磷酸盐玻璃光波导激光器性能的几个主要因素。
L yb - 7442 four - trace double - track recording and playing magnetic heads has won grade two award for science and technology advancement of shenzhen city Rp - 7442四迹双道录放磁头获得深圳市科学技术进步二等奖
375 the standards “ gb ” and “ yb ” provide the method of testing for materials in our country just like the standard astm in america 在我们gb (国标)和yb (冶标)规定材料的试验方法,正如美国的astm标准一样。
Yb : oh , i see . the easter island was originally a part of a continent plate . it became a separated island after the excursion of the plate 海尔弟:噢,我明白了。复活节岛原本是大陆的一部分,大陆板块漂移才成为今天的岛。
375 the standards “ gb ” and “ yb ” provide the method of testing for materials in our country just like the standard astm in america 在我们gb (国标)和yb (冶标)规定材料的确是的试验方法,正如美国的确是的astm标准一样。
Xps shows that the crystal has elements w , k , yb , o , gd from the data of electron energy level and binding energy 因此,若想生长质量优良的晶体,应尽量减少生长过程中的温度、浓度及生长速度的波动,保持晶体的稳态生长。
The energy levels and the spectrum of the yb ~ ( 3 + ) - doped crystals were introduced . theheoretical threshold of the different crystals was calculated 在介绍yb ~ ( 3 + )离子能级结构、光谱特性的基础上,计算了对应不同能级劈裂的晶体的理论阈值。
Each chemic and physical characteristics of phosphate glass is discribed , the compounding and fabrication of er / yb co - doped phosphate gain material are argued 对磷酸盐玻璃的各种成份进行了测试,然后通过熔制得到铒镱共掺磷酸盐增益玻璃材料。
Furthermore the optic spectrum data of er / yb co - doped phosphate glass , such as absorption spectrum , fluorescence lifetime and emission spectrum etc . are also tested 此外还对铒镱共掺磷酸盐增益玻璃材料的吸收谱、荧光寿命、激发谱等光谱性能进行了测试。
