这样才能准确地确定变量和结果之间的关系。Ignore the influence of other factors是不科学的做法,因为其他因素可能会干扰结果;Change all variables randomly会使结果变得混乱无法准确得出结论;Skip the control group是错误的,控制组是对比实验结果的重要部分。这题考查实验设计的原则。

Light is created from electromagnetic energy, which is formed from burning gases. Learn about light and its properties of reflection, absorption, and transmission. What Is Light? Annie's family was having a bonfire last weekend. It was getting dark outside, so she stayed near the bonfire. ...
We study the properties of the entropy and phase of the field in the two-photon Jaynes-Cummings model with an added Kerr medium. The influence of the nonli... MF Fang,HE Liu - 《Physics Letters A》 被引量: 94发表: 1995年 Quantum properties of light in the two-photon T-C model in...
Since the dawn of history philosophers have sought to explain vision and the behaviour of light. David Park ranges across almost 25 centuries from the Anci... Neil,Brown - 《Physics Education》 被引量: 53发表: 1999年 The Fire within the Eye: A Historical Essay on the Nature and Meaning ...
In this explainer, we will learn how to describe the properties of laser light and use technical terms to refer to these properties. We will see that light that comes from lasers is not like light that comes from other sources such as a light bulb or the Sun. We will name and describe...
The dynamical properties of light squeezing of two entangled atoms interacting with light squeezing in the system of coherent state are studied by means of the quantum theory.The results indicate that the squeezing of the optical field depends on the degree of entanglement of two identical atoms.In...
The apolar behavior of such nanostructures was experimentally confirmed by way of localized surface plasmon resonances (LSPR) properties and surface-enhanced Raman scattering (SERS) measurements. 展开 关键词: Gold nanoparticles Light polarization Symmetry point group ...
