1)  V-Q curve method
V-Q曲线法
1.
The method can combine some buses which have the same V-Q curves into a coherent bus group,and facilitate us to examine those concerned bus groups and their reactive reserve basin(RRB),in this way,it can greatly elevate the efficiency of V-Q curve method in obtaining the voltage stability margin.
该法将电网中具有相同V-Q特性曲线的母线合为母线组,在电压稳定分析中,只需分析重要的母线组及其无功储备源,大大提高了V-Q曲线法获取电压稳定裕度的效率。
2)  V-Q Curve
V-Q曲线
3)  Q-Bézier curve
Q-Bézier曲线
1.
The curve inherits the most properties of cubic Bézier curve and the shape of Q-Bézier curve can be adjusted by alerting the two shape parameters when the control polygon is maintained.
Q-Bézier曲线不仅具有三次Bézier曲线的特征,而且在控制多边形保持不变的条件下,具有形状可调性和对控制多边形更好的逼近性。
4)  Q-S curve
Q-S曲线
1.
Analysis of Q-S curve on negative frictional pile under large-scale vertical loads;
受大面积堆载影响负摩擦桩的Q-S曲线分析
2.
According to this characteristic,we may analysis pile body frictional resistance situation through the Q-S curve indirect,Compared to the case complex pile body stress observation,t.
通常情况下桩身摩阻的分析需要借助桩身应力观测,但对于摩擦型的长桩在非极限荷载的情况下,其荷载的作用增量基本转化为桩身的摩阻增量,且荷载的作用深度是渐进的,根据这一特征可以通过Q-S曲线间接分析桩身摩阻的变化情况,相对于复杂的桩身应力观测而言,该方法不失为一种较经济的分析手段。
3.
For the purpose of improving the rationality and reliability of pile design,on the basis of analyzing the characteristic of pile s static load Q-S curve,a "one element multi item format" is adopted to fit and predict a pile s Q-S curve.
为了使桩基设计更加合理可靠,在分析桩基静载试验Q-S曲线性质的基础上,采用一元多项式对桩基的Q-S曲线进行拟合及预测。
5)  Q~'s Curves
Q~S曲线
6)  Q-s curves
Q-s曲线
1.
The results show that Q-s curves calculated and measured are close to each other.
可以发现计算与实测的Q-s曲线非常接近;墩底端阻力的发挥严重滞后于墩侧摩阻力,墩顶荷载主要由端阻力承担,属摩擦端承型;扩大头侧面与土体接触处产生裂缝,裂缝首先在侧面下部产生,随荷载增加逐渐向上发展直至贯通,最大裂缝宽度达4。
2.
The study then starts with the calibration of single pile by analyzing the possible reasons to induce the difference between the measured and calculated Q-S curves.
先对一根试验桩进行验证计算,分析计算Q-S曲线与实测Q-S曲线存在差别的原因,然后对38根不同嵌岩深度和不同桩径的泥岩桩进行计算,模拟出泥岩桩的Q-S曲线和Q-z曲线,并对其统计分析,进一步论述了泥岩桩的荷载传递过程及其承载性状。

性质:又称塔菲尔(Tafel)线外推法。一种测定腐蚀速率的方法。做法是将金属样品制成电极浸入腐蚀介质中,测量稳态的伏安(E~I)数据,作log|I|~E图,将阴、阳极极化曲线的直线部分延长,所得交点对应的即为logIcor,由腐蚀电流Icor除以事先精确测量的样品面积S0,即得腐蚀速率。此法快速省时,适用于金属均匀腐蚀的测量。
