square wave

基本解釋

Pulse Width Modulation device is a circuit which can produce square wave signal with fixed period and adjustable pulse duration ratio (pulse width).
脈寬調(diào)制器是一種能夠產(chǎn)生周期固定而占空比（脈寬）可調(diào)的方波信號(hào)的電路。
High-precision DC signal is as testing of the static characteristics of the system, square wave signal is as testing the dynamic characteristics of the system.
高精度直流信號(hào)輸出用作測(cè)試系統(tǒng)的靜態(tài)特性，方波信號(hào)輸出用作測(cè)試系統(tǒng)的動(dòng)態(tài)特性。
Hardware and software designs are amply introduced in the paper and through the test analysis using square wave'the feasibility and validity of this design are affirmed.
詳細(xì)地介紹了系統(tǒng)的硬件設(shè)計(jì)和軟件設(shè)計(jì)，并在仿真的基礎(chǔ)上通過(guò)對(duì)方波信號(hào)的試驗(yàn)分析，驗(yàn)證了系統(tǒng)設(shè)計(jì)的可行性和正確性。

And when we take the wave function and square it, that's going to be equal to the probability density of finding an electron at some point in your atom.
當(dāng)我們把波函數(shù)平方時(shí)，就等于在某處,找到一個(gè)電子的概率密度。

So again if we look at this in terms of its physical interpretation or probability density, what we need to do is square the wave function.
如果我們從物理意義或者,概率密度的角度來(lái)看這個(gè)問(wèn)題，我們需要把波函數(shù)平方。

So, at this place where it hits zero, 0 that means that the square of the wave function is also going to be zero, right.
它達(dá)到0的地方，這意味著波函數(shù)的，平方也是,如果我們看概率密度圖。
