"Boule"相关例句(15)
3.You may form the loaves into boule, or any other style that pleases you.
4.The quality, optical transmissivity and homogeneity of the sapphire boule have remarkably improved.
6.YJD 90 brown boule has characteristics of high Al 2O 3 content,low micro porosity,corrosion resistance and better thermal stability etc. .
7.We have studied the growth method of Nd: LMA crystal and obtained a c-abxis boule with the size of (26×180mm) and an α-axis boule with the size of 27×13×160mm. From those boule, we obtained several laser rods with size φ5～7×60～110mm. The highest slope efficiency is about 4.5 percent and the interference fringe is 0.5/25mm.
8.The as-grown sapphire boule (φ110×80mm3) turns out colorless and transparent after being decolourized and decarbonized in air and hydrogen successively at high temperature.
9.XRD and DTA curves of the powder from the GSO boule were measured to interpret the cracking of the boule. The absorption and fluorescence spectra at room temperature were also investigated, from which we examined that the emission peak of GSO:Ce crystal is at 433 nm,and the transmission in the region of over 400 nm is larger than 80%.
10.Several high quality crystals of AgGaSe2 have been grown utilizing the vertical Bridgman technique. Boule sizes were typically 20 mm in diameter and 80 mm long.
11.Single crystals have been grown with a boule size of ?40×70mm and plate size of 20×20×1mm 3. The dielectric constant ε is ～5000, loss tan δ<0.9%, piezoelectric constant d 33 >1500pC/N,and coupling k 33 ～94%.
12.A crystalline sapphire (Al_2O_3) boule (?110×80mm3) grown by the temperature gradient technique (TGT) is a bit colored due to carbon volatilization from the graphite heater at high temperatures and the absorption of transitional metal inclusions in the raw material.
13.From the crystal boule grown, a high quality laser crystal rod of up to 3 mm in diameter and 11.9 mm in length was cut out. Absorption spectrum of this crystal ranging from violet to infrared was measured.
14.The optimal annealing processing is as follows: in oxygen atmosphere Yb∶YAG crystal boule is fired at 1 600 ℃ for 36 h, and then cools to room temperature at a rate of 10 ℃/h. After annealing, the crystal changes from blue to colorless, suggesting that Yb 2+ and color center are eliminated. The distribution of Yb 3+ in Yb∶YAG was characterized by the intrinsic absorption performances of Yb∶YAG at 940 nm.
15.Along the vertical axis of the crystal,the change of size and density of Ir particlesin the boule of crystals has been derived and the limit size l_(lim)(V) of an Ir particle forrepulsing it at a definite growth rate has been found. The optimum growth rate of GGGand doped GGG without Ir inclusion is found by extrapolating l_(lim)(V).
