Because P and S waves travel at different but fairly constant speeds, the interval between their arrivals increases in proportion to the distance from the earthquake focus, or initial rupture point.
由于P波和S 波以不同但相当恒定的速度传播，它们到达的间隔与到震源或初始破裂点的距离成比例地增加。
Let's just suppose, as seems likely, that none of the P-functioning is occurring, at some point during sleep.
我们就这样设想一下，在睡眠的某个时间点上，没有任何人格功能性。
And that explains why H-P keeps hammering on this point about 'confidential information'.
这就解释了惠普为何一再强调“机密信息”这一点。
But I don't care about that force because I'm going to take the torque about point p.
但是，我不在乎这些力，因为我要取的是，点p的力矩。
So if I take the torque relative to point P, then I have...
如果取点P的,力矩，那么就得到…
The formal definition is that the gravitational potential energy at a point P is the work that I, Walter Lewin, have to do to bring that mass from infinity to that point P.
形式定义就是,它在点P的重力势能,等于我，将物体从无穷远处,移动至点P所做的功。
So, maybe my point, P, now, is here.
点P，现在在这。
And angular frequency is the square root inertia about point p.
角频率是，点p的转动惯量。
This point, p, was there, and the amount by which the things have moved can be measured either here or here.
这是点P，移动的总量，可以认为是这到这。
So it is bMg divided by the moment of inertia about that point P.
也就是bMg除以,点P的转动惯量。
Well, at point P, the velocity vector QP is perpendicular to the line QP, 1 so the sine of that angle is one.
点P，速度向量,垂直于直线，所以该角的正弦值为。
Let's first look at the situation at point p.
首先请看点p的情形。
这是点。
So, the position of this point, p, is going to be the same as OP knowing the vector OP from the origin to this moving point.
点p的位置就是，从原点指向这个运动点的向量。
Share index futures dropped 99 points to 3, 995.0, a 146.3 point discount to the close of the underlying S&P/ASX 200 index .AXJO.
澳大利亚股指期货下跌99点，至3 995.0，比该期货标的——澳大利亚S&P/ASX200指数.AXJO在上一交易日收盘时的点位低146.3。
What is your kinetic energy when you reach point p?
所以到达点P时的，动能是多少？
这是点。
P This is point p, and here is the center of the rod.
这是点，这是杆子的中心。
P So here at the bottom, at this point P, there is a loop.
在底部，点，有一个环。
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。
Historian A. J. P. Taylor once called 1848 a moment when "history reached a turning point and failed to turn."
历史学家A·J·P·泰勒曾将1848年称作一个“历史到了转折点，却转折失败”的时刻。
So for example I defined p, remember back over here, as a Cartesian point, but I can actually ask for its polar form.
我可以要求返回它的极坐标形式，这里对我是可访问的，好，这很棒，请再记另外一个为什么。
Point out the letters S-T-O-P. Later, you can point out an "s" on a store name and then ask if she can find some more.
写出s- T - O - P这些字母，然后可以写出s开头的商店名，问孩子是否她可以给出更多类似的。
What is the situation at point p?
那么点P情况如何？
p2 It's taking the name p 1 and it's changing its value to point to exactly what p 2 points to.
我要把p1赋值为1,这个操作有什么用呢？,这个操作把p1这个名字的,指针的值改变让它。
the position of the highest point P we first ask ourselves the question from equation number four: 0 when is the velocity in the y direction zero?
为了找到最高点P的所在,我们首先得,解答我们刚才提出的问题：,究竟何时y方向上的速度减为？
p I put the point in an awkward place xB Let's put it right there. p1, and composition xB.
等于p1，我再次选择，p，is，equal，to，p1。，Again，一个比较棘手的位置,放在这，p1和组分比。
Once you created a 'd', this could work fine as a starting point for a 'b' and a 'p', by rotating the 'd' 180 degrees.
当你完成了一个“d”，你就可以把这个“d”旋转180度，以此为基础完成“b”和“p”的制作。
At that point, typing the Control-p key combination writes the contents of the screen to your output file.
此时，键入Control - p组合键，将屏幕内容写到输出文件。
Let's call it q. P is the point that coordinates x, y, h.
就叫它q,p的坐标是。
