1) initial core
起始核心
1.
2,4 - dihydroxymethyl - 1,5 pentadiol and inositol used as four - and six - directional initial cores were oxypropylated first in order to decreased steric hindrance, then reacted with branched building blocks, followed by deprotection to give title compounds.
本文选用2,4-二羟甲基-1,5-戊二醇和肌醇为四方向及六方向起始核心,通过氧丙基为空间间隔基与带保护基的分支侧链成醚,脱保护后得未端官能团数为原母核两倍的新型有机分子——四方向及六方向醚键型分枝状化合物。
2) nuclei of origin
起始核
3) eukaryotic initiation factor 5A
真核起始因子5A
4) onset of nucleate boiling
泡核沸腾起始点
6) prokaryotic initiation factor
原核起始因子
补充资料：UG起始为公制之设置
UG起始为公制设置 安装目录 ……\EDS\Unigraphics NX 2.0\UGII 下 ugii_env.dat 文件中有如下内容：
“ # This variable defines the ascii file that contains
customer defaults used # by Unigraphics.
There are two files available: ug_english.def and #
ug_metric.def UGII_DEFAULTS_FILE=${UGII_BASE_DIR}
\ugii\ug_english.def ” -------------- 文中 ↑↑↑ 用
ug_metric.def替换 ug_english.def
