The flow stress can be described by temperature - compensated strain rate , the so - called zener - hollomon parameter 利用7055鋁合金高溫塑性變形時(shí)穩(wěn)態(tài)流變應(yīng)力、應(yīng)變速率(
The basis topologies for the band - gap , buried zener , and xfet references are shown in figures 1 , 2 , and 3 , respectively 關(guān)于帶隙基準(zhǔn)、掩埋齊納二極管和xfet基準(zhǔn)的基本拓?fù)淙鐖D1 、 2和3所示。
Modern voltage references are constructed using the energy - band - gap voltage of integrated transistors , buried zener diodes , and junction field - effect transistors 現(xiàn)代電壓基準(zhǔn)建立于使用集成晶體管和帶狀能隙基準(zhǔn)、掩埋齊納二極管和結(jié)場(chǎng)效應(yīng)晶體管。
The double exchange interaction founded by zener in early 1950 ' s , and developed by anderson and de gennes later is a better theory in describing the conductive behavior in the compounds 最后由anderson等人發(fā)展了五十年代初期由zener創(chuàng)立起來(lái)的雙交換作用理論,為解釋龐磁電阻效應(yīng)提供了一條途徑。
We are your specialist for semiconductor diodes and rectifiers : standard to ultrafast recovery , schottky , zener , supressor - diodes , bridge rectifiers , transistors , diacs ; also customized 我們是專門(mén)提供二極管以及整流器,例如:標(biāo)準(zhǔn)到超快速恢復(fù),肖特極,穩(wěn)壓,雙向觸發(fā)二極管,橋式整流器,轉(zhuǎn)換器等等,可以依照客人要求訂做。
Buried zener - based references are frequently used for 12 - bit , 14 - bit , and higher resolution systems because the performance of the buried zener - based references can be extended by incorporating nonlinear temperature compensation networks into the design 在設(shè)計(jì)中使用非線性溫度補(bǔ)償網(wǎng)絡(luò),掩埋齊納二極管基準(zhǔn)的性能可以進(jìn)一步提升,因此掩埋齊納二極管基準(zhǔn)經(jīng)常用于12位、 14位和更高分辨率的系統(tǒng)中。
We studied the influence of the interface strain and it shows that the lattice mismatch between substrate and film is the main reason of the above observations . expand strain decreases tm - i with increasing resistivity and compressed strain has the opposite effect . using double exchange model of zener these results can be explained qualitatively 27歐姆厘米,轉(zhuǎn)變溫度是78與154開(kāi)爾文,磁場(chǎng)強(qiáng)度為7t時(shí),磁阻率為習(xí)3及巧6 x結(jié)合雙交換模型和不同的應(yīng)力作用,逐一解釋了產(chǎn)生差異的緣由,其中我們也討論了具有)取向的la 。
Firstly , i provide a brief review of the previous achievements and investigations on the low - dimensional quantum devices and semiconductor superlattice , in which some principal theories such as bloch oscillations , wannier - stark ladder , zener tunneling and related progress in experiments are introduced 首先綜述了過(guò)去三十年低維量子器件與半導(dǎo)體超晶格的發(fā)展與相關(guān)研究,介紹了bloch振蕩、 wannier - stark臺(tái)階、 zener隧穿等關(guān)鍵理論以及相關(guān)實(shí)驗(yàn)方面的進(jìn)展,并引入簡(jiǎn)化模型:緊束縛模型與單帶模型。
That is the reason that all over the countries have never stopped researching for mask jamming technology of radar . at present , the mask jamming source mainly comes from the thermal noise and zener avalanche noise of semiconductor devices . but the noise ’ s quality isn ’ t stabile because of the differences of semiconductor devices each other and the changes of exterior conditions 目前采用的遮蓋性干擾的噪聲源主要來(lái)自半導(dǎo)體器件本身的熱噪聲或齊納雪崩噪聲,但各器件本身的不一致性和外界條件變化等因素使噪聲輸出質(zhì)量不穩(wěn)定;同時(shí)由于此類信號(hào)不能再生,不利于科學(xué)研究。
