句子 Instead of working with light, however, he worked with microwaves, which have a much longer wavelength, and built a device he called a "maser" for Microwave Amplification by the Stimulated Emission of Radiation. 问题 句子分析(俗称“长难句分析”)是训练提高基础阅读能力的有效手段。我们通过对...
Light of the wavelength which is longer than the wavelength where it dopes in SiPROBLEM TO BE SOLVED: To provide a semiconductor control circuit element which can control an electric circuit at a high speed, by quickly and remarkably changing only a part of the resistance of the element ...
Compare blue and orange light from the visible spectrum. Between the two lights: 1) Which has the longer wavelength? 2) Which has a greater frequency? 3) Which has greater energy? Electromagnetic radiation with a wavelength of 589 nm appears as yellow light...
The fact that the same method, concealment, may be used both for attack and defense has been well explained by T. Belt who suggests as an illustration the rapidity of movement which is also made use of by both pursuer and pursued, which is similarly raised to a maximum in both by the ...
All waves can be measured using amplitude and wavelength. While the waves created by a boat have very small amplitude—sometimes as small as a few centimeters—the wavelength can be very short, as lots of waves are being generated. By contrast, a tsunami has very high amplitude, sometimes mo...
19. The device according to claim 15, further comprising a fluorescent material which absorbs the light emitted by said organic hole transport layer and emits light having a longer wavelength than that of the light emitted by said organic hole transport layer, said fluorescent material being added...
This wavelength stability requires the laser diode temperature to be controlled and often the laser diode to include an additional wavelength stabilizing element. This element is generally a FBG (Fiber Bragg Grating) for single mode laser diodes (a specialized piece of fiber situated roughly 1 meter...
exhibits said another of said at least two crystalline structures; wherein said alloy has a martensitic transformation temperature wherein said alloy has a martenisitic transformation temperature lower than room temperasture; wherein recording or erasing is carried out by utilizing a change in any of...
Science has to do with the way questions are formed and answered; it is a set of rules and forms of inquiry created by people who want reliable answers. (1)According to the passage, which of the following statements is correct? ___ [ ] A.Science helps people understand the world. ...
In this structure, there is a single GapR monomer in the asymmetric unit. It has an extended N-terminal α helix followed by two shorter α helices (Fig. 1a). The three helices are relatively open and not bundled together, suggesting that this conformation would not be stabilized in the ab...
