1) parameter of crystallization tendency β
析晶倾向参数β
2) crystallization power,tendency,towards devitrification
析晶倾向
3) crystallization parameter
析晶参数
1.
The results showed:When less than 2mol% Fe_2O_3 was introduced into glass,the crystallization parameter of glass-ceramics was possibly increased,and almost all the samples' temperature range from Tp to Tg overlapped partly,that means glass samples can be crystallized at the same temperature.
结果表明,少量铁(<2mol%)的引入,可能引起析晶参数的升高,但外加铁含量超过2mol%时均可降低析晶参数,并使起始析晶至析晶峰的温度区间(Tp-Tg)变窄;外加铁量<2mol%时,不同含铁量配方的(Tp-Tg)区间重叠显著,可以采用同一温度晶化处理;配方含铁与否对主晶相没有明显影响,但影响玻璃的析晶能力,铁含量<2mol%时,使玻璃体析晶能力增加,接近或大于3mol%时,玻璃析晶能力降低;微粉制备微晶玻璃可以大幅度缩短晶化时间。

This article explored the variation of cotton fiber orientational parameters and its relation to fiber strength with the method of planting cotton by stages at the sites from the Yellow River Valley to north Xinjiang.
采用不同生态棉区选育的棉花品种,在新疆库尔勒、石河子和河北南宫市3地进行"异地分期种植比较",研究了棉纤维的晶区取向参数的变化及其与纤维比强度的关系,结果表明:随纬度升高,由中熟棉区向北疆早熟棉区推移过程中,晶区取向参数升高,纤维比强度降低。
5) tilted angel
晶向倾角

Measurements using X-ray double crystal diffraction(XDCD) were carried out to investigate the tilted angels of ZnTe and CdTe epilayers grown on 76mm Si(211) and GaAs(211)B substrates by molecular-beam epitaxy.
本文采用X射线双晶衍射二次测量法对76mmSi(211)和GaAs(211)B衬底上生长的ZnTe和CdTe外延层的晶向倾角进行了测量,发现对于Si和GaAs衬底,外延层的[211]均绕外延层与衬底的[0-11]复合轴朝[111]倾斜,其晶向倾角与晶格失配呈线性关系;通过实际测量验证了在外延层探测到的[133]峰代表[211]关于[111]旋转180°的[255]孪晶向。
