疇雙晶 的英文怎麼說
中文拼音 [chóushuāngjīng]
疇雙晶
英文
domain twinning-
The experiments showed us : firstly, mediums with different magnetic and dielectric properties had different influence on the microwave - absorbing properties of spinel ferrite ; secondly, magnetic texture treatment greatly affected the microwave - absorbing properties of the spinel ferrite - based mixed material which contained single - domain particles of hexagonal ferrite, changing the matching thickness, the density of area and the position of absorption peaks and increasing the absorption quantity and the 10db bandwidth ; thirdly, the coupling effect between different layers affected the microwave - absorbing properties of the double - layer spinel ferrite - based mixed material, decreasing its matching thickness and density of area and increasing the position of absorption peaks
實驗發現： （ 1 ）不同磁性與電性的介質對尖晶石型鐵氧體吸波特性的影響不同； （ 2 ）磁織構化處理對含有六角晶系鐵氧體單疇顆粒的尖晶石型鐵氧體基混合吸波材料的性能影響很大，可以改變匹配厚度、面密度與吸收峰峰位，提高吸收量與10db帶寬； （ 3 ）對于雙層材料，層間耦合作用會影響其吸波性能，降低匹配厚度與面密度，提高吸收峰峰位。We discuss the relationship of the properties of the wavelength tuning v. s. applied voltage > working temperature and duty - cycles when the voltage applies on the single domain or the dual domain
討論了ppln在單疇、雙疇分別加電壓的情況下，其波長調諧特性與外加電壓、晶體溫度及占空比的關系。From the results, the applied voltage is too large while the voltage applies on the single domain or the whole domain in shg process, which will spoil the ppln crystal and can not satisfy the require in experiment
由計算結果可知，無論在單疇加電壓或雙疇加電壓時，需要的電壓都太大，可能造成對ppln晶體損壞，無法滿足實驗中的實際要求。
