  1. In this paper, such three points are studied as : a ) the angular distributions of the hot electrons emission under laser irradiation at different incidence angles and at different polarization direction, the angular distribution of the hot electrons in the different energy range, and the effects of laser prepulse on the angular distributions of the hot electrons emission ; b ) the energy distribution of the hot electrons at different directions, from the metallic targets and the dielectric targets, in the different energy range of the hot electrons, and the effects of the atomic number z on the energy distribution of hot electron generated by the metallic targets ; and c ) the energetic proton emission resulting from the interaction of the us - ui laser pulse with plasma

  2. Electrorheological ( er ) fluid is a kind of smart material. er fluids typically consist of electrically polarizable particles dispersing in low - dielectric oils. application of an electric field can induce polarization of the suspended particles

    電流變液( electrorheologicalfluids )是一種智能材料,通常是高介電常數的微小顆粒分散在低介電常數的絕緣液體中形成的懸浮體系。
  3. The natures of the probe and formation mechanisms in these techniques are different ; therefore, the images of spm can reflect different properties of sample surface. in this work, related properties of ferroelectric thin film were investigated as followed : the main factors determining the image formation of piezoresponse force microscopy ( pfm ) and scanning nonlinear dielectric microscopy ( sndm ) were studied. to avoid the misreading of the same conductive tip with different state, a new method of polarization distribution mapping with nonconductive tip was proposed, and the result of experiment demonstrated that the polarization distribution of ferroelectric thin films could be characterized well by the new approach

    本工作主要分為以下幾個部分:從研究鐵電薄膜的壓電響應力顯微鏡( pfm )和掃描非線性介電顯微鏡( sndm )成像的影響因素入手,討論了針尖對成像質量的影響;為降低實驗成本、減小導電探針針尖狀態變化對鐵電薄膜微區電性能測試的負面影響,提出了以非導電探針檢測微區極性分佈的方法,並在現有spa - 300hv型spm的實驗平臺上以pfm模式成功實現了新方法對鐵電薄膜極性分佈的表徵。
