1) Advance core
待挖核心体
1.
The key of maintaining the tunnel stability lies on how to deal with the advance core soil ahead of working face,which is obtained on basis of analysis on the problems in high speed railway tunnels with big cross-sections in soft surrounding rock or soil.
总结分析了目前高速铁路大断面软弱围岩或土质隧道施工中存在的问题,认为如何处理好掌子面前方的"待挖核心体"是控制此类隧道整体稳定性的关键,运用沿隧道纵向全断面预加固的易切削玻璃纤维锚杆来提高"待挖核心体"的等效刚度,控制"待挖核心体"的变形,使得隧道周边的拱效应能自然发挥作用,可以保证隧道能够全断面安全、顺利开挖掘进。
2) digging out sands to wait for deposition
以挖待沉
1.
When sand sinking pools are full and lose efficacy, the method of “digging out sands to wait for deposition” can increase the life of irrigation region.
当沉沙池淤满，失去自流沉沙作用时，采用“以挖待沉”可以延长灌区运行年限，但没有扬水沉沙方案优越。
3) HBcAb
核心抗体
1.
ResultsAll sorts of liver impair including liver cirrhosis might occur on the patients who had negative HBsAg and positive HBsAb,HBeAb and HBcAb.
目的探讨乙型肝炎病毒表面抗原(HBsAg)阴性,而乙型肝炎病毒表面抗体(抗-HBs)阳性、e-抗体(抗-HBe)阳性、核心抗体(抗-HBc)阳性时慢性肝损害发生的原因、治疗及预后。
4) core tube
核心筒体
1.

假定了适用于分析四面开洞核心筒体扭转特性的位移函数，推导了计算连梁剪力及核筒扭转角的简单公式。
2.
Based on the supposed displacement functions, the fist twist vibration frequency of the core tube with holes on the four sides of a single core tube hanging structure is denved by use of the variational method.
在假定位移的基础上，用能量变分法推导出核心单筒式悬挂结构中四面开洞核心筒体的扭转振动基本频率。
5) core population
核心群体
6) nuclear celestial body
核心天体
