factor of safety

基本解释

The choice of a suitable value for the factor of safety also presents great difficulties.
选择适当的安全系数值也存在大的困难。
Knowing the strength, it is possible to work backward and determine what factor of safety was used.
由于知道其强度，便可以反过来求出所用的安全系数值。

Under the condition of the least factor of safety, the relations are discussed between the geometry parameters of slip surfaces and the factors of safety.
并在安全系数为最小的条件下，讨论了滑动面几何参数之间以及它们与安全系数之间的关系。

This incorporates a safety factor of 1, 000 on the lowest observed adverse effect level of antinomy in animals--in other words, the first statistically significant health problem in animals came from inhaling antimony at a level of 9000 micrograms per meter cubed.

the ratio of the breaking stress of a material or structure to the calculated maximum stress when in use (Also called safety factor)

安全系数
It is difference from traditional factor of safety method, probability analytical method consider dispersed quality and dependence between parameters of soil in stability analysis of slope.
区别于传统的安全系数法，可靠性分析方法在对边坡稳定性的分析中考虑了岩土参数的离散性及参数之间的相关性，用概率的方法定量地考虑了实际存在的种种不确定因素，因而更为客观、定量地反映了边坡的实际安全性。
