1) major axis
主轴，长轴
2) lengthening spindle
加长主轴
1.
To surmount the difficulty of machining spindles with inverted taper bore, the methods such as lengthening spindle, using template, making machine tool rotate reverse, translating tool bar and so on are adopted to ensure the concentricity, taper and size accuracy of spindles with inverted taper bore.
针对带内锥主轴加工难的问题,采用加长主轴、利用样件、机床反转、刀杆平移等方法,来保证带内锥主轴和内孔的同轴度、锥度以及尺寸精度。
3) semi-major axis
半主轴;半长轴
4) total tassel length
雄穗主轴长
1.
On the basis of 103 SSR linkage map,QTLs associated with tassel branch number (TBN) and total tassel length (TTL) were studied by composite interval mapping with F3 families,which were developed from the cross N87-1 × 9526 and surveyed for phenotype under normal condition (CK) and drought-stress environment (DS).
雄穗主轴长在正常环境下被检测到2个QTL位于第2和第6连锁群上,在干旱胁迫环境下被检测到了3个QTL分别于第2、4和10连锁群上,其中位于第2染色体上的QTL是两种环境下所共同检测到的QTL。
5) rhizome growth characteristics
主轴生长特性
1.
fastiniata\'s age could be determined according to the rhizome growth characteristics,combining with the length of the rhizome.
在西藏色季拉山区不同海拔带设置样地,观测长鞭红景天花茎环的形成过程,用游标卡尺(IP54型)测量长鞭红景天植株不同年的轴向生长量和径生长量;分析其主轴生长特性,进行年龄判定,结果表明:长鞭红景天每年在主轴上形成一个花茎环结构,并且轴向生长量和径生长量在年际间均无显著差异,但随海拔升高,轴向生长量和径生长量均呈下降趋势。
6) spindle bearing
主轴轴承
1.
Three dimensions CAD system used in spindle bearing of aircraft engine;
航空发动机主轴轴承三维CAD系统
2.
This paper discusses the working condition of machine tool's spindle bearing can be distinguished by bearing's vibration signal.
论文阐述了利用轴承振动信号可判断机床主轴轴承的工作状态,通过频谱分析可对轴承进行故障诊断及预紧力确定;应用B&K2148采集振动信号,MATLAB进行数据处理,对CKS6116型机床主轴前轴承进行了故障诊断与预紧力分析并取得了满意的效
