So the temperature effect studyied of mica crystal is much less and the research
作为制作单级波片的理想双折射材料云母晶体,由于其晶片太薄,极易产生多次反射,且孔径稍大时面形难以保证,因此研究其温度效应的更少,对云母晶体最大双折射率温度系数的研究至今尚未见到报道。
The inherent discrepancy of birefingent dispersion relations of mica crystal has an unfavourable effect on designing wave-plate.
针对云母晶体材料本身性质所决定的双折射率色散关系不一致性,给波片设计带来非常不利的影响,提出偏光干涉法研究云母的色散特性。
The variation of temperature has an effect on maximal birefringent index of mica crystal, which accordingly influences the use precision of mica wave-plate.
由于湍度会对云母晶体的最大双折射率产生影响,影响云母波片的使用精确度。
2%, the cell volume will contract by entering Ce~(4+) into the A-site of the samples with single perovskite phase, while the cell volume will expand by entering Ce~(4+) into B-site.
样品介电常数随Ce4+含量的增加先增大,后减小,介电常数的增大是由于晶胞体积的收缩以及相对密度的增大;减小则是由于Ce4+的半径(0。
The samples obtained were then charged and discharged for 100 cycles to determine their maximum discharge capacity Cmax, and cell volumes Vcell of some alloys were measured.
制备了6个系列通式为A_αA_(1-α)B_5的RE(NiCoMnTi)_5贮氢电极合金(其中,A_αA_(1-α)为La,Ce,Pr,Nd 4个元素中任意2个的组合),测定了它们在100次循环中的最大放电容量C_(max)及部分合金的晶胞体积V_(cell),结果表明:C_(max)主要由V_(cell)决定,C_(max)先随V_(cell)的增大而增加,在V_(cell)≈85。
With increasing dopant content, their lattice constants and cell volume decrease, average valence of Mn increases, and initial specific capacity in 4 V range decreases.
讨论了掺杂对尖晶石高电位 (>4 5V)区容量的影响 :掺杂后的尖晶石锂锰氧化物仍保持尖晶石结构 ,但与未掺杂的尖晶石锂锰氧化物相比 ,它的晶胞常数减小 ,晶胞体积收缩 ;锰元素的平均化合价升高 ;4V区的初始容量减小 ;循环稳定性明显增加。
2 A·g -1 increased with increase of unit cell volume of the alloy in the range of x=0.
２Ａ／ｇ－１下，放电比容量随合金晶胞体积的增大而增加。
