Another way to increase intensity is the frequency of firing.
另一种会增加反应强度的因素,就是神经冲动产生的频率
-
The mean proportion-- The mean of x/n, is equal to p.
事件发生频率的均值,即x/n的均值,就等于p
-
So, if something cycles through five wavelengths in a single second, we would just say that the frequency of that wave is five per second.
如果一个东西在一秒,内经历了五个波长，我们就说这个波的,频率是每秒5次。
-
So really what we'll probably do is instead either give you the wavelength or the frequency and you'll go ahead and calculate the energy from there.
所以实际上我们可能的做法是,给你波长或者频率,然后你可以通过他们计算得到能量。
-
Maybe you can put the frequency of the higher pitches as high so you can detect the sound quicker and That's it exactly.
大概是把频率调到更高的音高后,就能更敏捷地感觉到声音的变化,而那就是原因了
-
The second one is the frequency of firing in that something is more intense if it's "Bang, bang, bang, bang, bang, bang" then "Bang, bang, bang" and these are two ways through which neurons encode intensity.
第二个是产生神经冲动的频率,如果先是 "砰 砰 砰 砰 砰",然后变成,"砰,砰,砰",这是由于神经元反应强度更大了,这便是两种,会影响神经元反应强度的因素了

The World Health Organization keeps track of what countries have cases of polio and when they occur, and what the frequency of--So, this is a map from a few years ago and there are efforts that occur occasionally.

-
Frequencies, how many times you go around, f is revolutions per second It's called the angle of velocity.
频率就是一秒转多少圈,因为 f 是每秒转过的圈数,这就是角速度
-
The formula tells us or absorbed based on the energy difference between the two levels that we're going between, that the electron is transitioning between.
这些公式告诉我们,或发出的光的，频率大小,是基于，电子转移的，两个能级，之间的能量差。
-
So, we should be able to look at different types of waves and be able to figure out something about both their frequency and their wavelength and know the relationship between the two.
我们可以看到,不同的波并从它们的,波长和频率中,获得一些信息，我们知道。
-
So, the take-home message is whether you have three photons or 3,000,000 photons that you're shooting at your metal, if you're not at that minimum frequency or that minimum energy that you need, nothing is going to happen.
所以，这里表明的信息是,无论是向金属发射3个光子,还是300万个光子,如果没有达到所需的最低频率,或者最小能量,什么事情都不会发生。
-
So it's centered at this frequency that was expected, but it's actually split into two different frequencies.
它的中心在预计频率处，但劈裂成两个不同频率。
-
Similarly, just as we have symbols for the presence of sound and its length, we have symbols that represent the absence of sound.
类似的,既然我们有符号,来表示声音的频率和长度,我们也有表示静音的符号
-
Well, actually they all have the same overtones in a way, the same frequencies will sound, but you've got it--ninety-nine percent of it.
事实上,它们的泛音大体是相同的,频率听起来也一样,但你已经答对百分之九十九了
-
And what they could come up with, what they reasoned, is that there must be some intrinsic property within the electron, because we know that this describes the complete energy of the orbital should give us one single frequency.
他们想到着一定和，电子的本征性质有关，因为我们知道这个轨道的,完整描述会给出单一的频率。
-
We want to figure out if the harmony is changing, and if it is changing whether it's changing at a regular or irregular rate.
一是判断和声是否发生了变化，二是如果发生了变化，和声的变化频率是规则还是不规则的。
-
So, this really just means for frequency, it's a frequency label.
你要说米每秒，所以它仅仅是，用来表示频率的，是个频率的标志。
-
The string is vibrating higher when it's exactly twice what the lower one is.
高音弦的震动频率,正好是低音弦的两倍
-
So these are symbols telling us how long a particular frequency is to endure.
因此,这些符号是告诉我们,某个特定的声音频率要持续多长时间
-
This grid of horizontal lines, and we will know that if we're going from here to here, it's got to be exactly this frequency, or at least this space.
这个水平线组成的网格,让我们知道,从这里到这里,正好是这样的频率,或者至少是这个间隔
-
So, it's up on this screen here now, so we'll work on the other one. If you can identify which of these statements is correct based on what you know about the relationship between frequency and wavelength and also just looking at the waves.
它们之间的关系,现在在大屏幕上了,鉴于你们知道,频率和波长的关系,看到这些波你们来,判断下这些说法是否正确。
-
So, for example, here we're showing rubidium and potassium and sodium plotted where we're plotting the frequency -- that's the frequency of that light that's coming into the metal versus the kinetic energy of the electron that's ejected from the surface of the metal.
让大家看来都是可以理解的事情,就是把不同金属的观测结果,画到一张图里面来，例如这里,我们展示的是钠，钾,铷的频率-这是照射金属的光的频率,和金属表面出射电子动能的关系。
