Through check, it is found that minimum excitation limit is calculated in P-Q plane, while impedance type loss-of-field protection is analyzed in R-X plane.
“发电厂并网运行安全性评价”要求验证低磁励限制与失磁保护的整定关系，在实际校核中，发现低磁励限制是在P-Q平面进行计算的，而阻抗型失磁保护是在R-X阻抗圆平面进行分析的。
Within that window, type screen -x -r sharing -p one.
在此窗口中，输入screen- x- rsharing - p one。
Well, the change in f is the value of f at the upper point here, which is x0+delta x, and minus its value at the lower point P, which is f of x0, divided by delta x.
f的变量就是f在上面的点时的值，x0+deltax，减去f在下面的点P时的值，x0，再除以delta x。
So we can have, if we have the final quantum number m equal plus 1 or minus 1, we're dealing with a p x or a p y orbital.
所以如果我们有,磁量子数m等于正负1,我们讨论的就是px或者py轨道。
We want to know whether a given vector field with components P, Q and R can be written as f sub x, f sub y and f sub z for a same function f.
要看向量场,能否写成，其中f是同一个函数。
The hydrothermal crystallization behaviour was also studied under the same conditions. Zeolites A, X, Y and P were crystallized in the area of precipitate, mixture, gel and sol respectively.
本文还研究了相同条件下的水热晶化行为，在沉淀区、混合区、凝胶区和溶胶区分别晶化得到沸石A、X、Y和P。
The X-ray at the final follow-up showed that there was insignificant difference in postoperative hip joint space, hip pain, or stem loosening between the two groups (P>0.05).
术后并发症情况：在深静脉血栓、髋关节间隙变化、疼痛、假体柄松动下沉等方面，两组比较差异无显著性意义（P＞0．05）。
