surface subsidence

The surface subsidence resulted from excavation of subway tunnel routeway is potentially hazardous, which requires monitoring in terms of the projects safety.

本文结合注浆及监测资料,从统计学的角度深入分析了地表顶升回落规律,评价了注浆效果。

On the basis of the experimental data,derived was the "non-dimensional volume-flow rate formula of a falling-back liquid curtain".

根据实验数据,推导出了"回落液幕无量纲体积流率公式"。

The distribution of falling liquid flow on upright water jet was studied.

在液幕式湿法脱硫中,竖直射流回落液量分布情况直接决定脱硫效率。

Objective:To observe the ST-segment resolution,creatine kinase cTnT and LVEF of patients with STEMI after direct PCI and TIMI flow reaching 3 grade in order to investigate the relationship between ST-segment resolution and myocardial damage as well as cardial systolic function.

目的:通过观察STEMI直接PCI术后,IRA达到TIMI血流3级患者心电图ST段回落程度,探讨ST段回落与心肌损伤及心脏收缩功能的关系。
