They are applied to different situations and verified by experiments. analysis model of small ap oblique penetrating ceramic / metal light armor is established on the basis of energy model and the assumption of ellipse absorbing the same energy in back plate, giving the predictable formula about ballistic limit velocity. with energy model the optimization design in relation to ceramic / metal light armor is analyzed and the optimal coefficient of ceramic / metal composite armor is gained
本文的主要研究內容如下： （一）建立了小型穿甲彈垂直侵徹陶瓷/金屬輕型裝甲的動量模型和能量模型，它們分別適用不同情況，並通過試驗驗證；基於能量模型和背板橢圓吸能相同假設，建立了小型穿甲彈斜侵徹陶瓷/金屬輕型裝甲的分析模型，給出了彈道極限速度預測公式；利用能量模型對陶瓷/金屬輕型裝甲的優化設計進行了分析，給出了陶瓷/金屬復合裝甲的最佳優化系數。 -
The paper takes shiyan city as a study case. in light of the existing urban recreationally spatial structure and its landform, the paper puts forward “ ellipse circle ” formed by “ plot - axis ”, an ideal model of recreationally spatial structure for moderate cities, which can be described as : according to “ plot - axis ” model, a city which has unique central district firstly puts emphasize on the center and its axes, secondly transfers to secondary center and its axes, thirdly gradually shapes a recreational belt crossing the center of the city, finally forms “ ellipse circle ” model for recreationally spatial structure by recreational belt. finally, the paper comes up with corresponding countermeasures aiming at the recreationally special layout of each hierarchy in shiyan city
以十堰市為例，根據城市現有的遊憩空間結構和地形特徵提出了「點軸」拉動的「橢圓圈層」城市遊憩空間結構模式，即對于只有一個中心區域的城市，根據「點軸」空間結構的發展模式，首先以中心區域為重點並發展其中心軸線，隨后把重點逐步轉到次重點區域並發展次中心軸線，照此循環下去逐漸形成橫穿城市中心區域的遊憩帶，在遊憩帶的作用下形成了城市遊憩空間的橢圓圈層模式;最後分別對城市社區、城區和環城三個遊憩空間的布局提出了相應的改進措施。 -
Analysis th to mechanism ellipse polarized light that in the specimen faced happen at the same time reflection refraction and multiplicity light beam interference, proves the principle that laser instrument of measure thickness of specimen with jones vector
摘要對橢圓偏振光在樣品表面產生的反射、折射和多光束干涉的機制進行了分析，並用瓊斯矢量論證了激光測厚儀的原理。 -
When the laser frequency is larger than the atomic resonance frequency ( blue detuning ), the atoms will experience a repulsing force that will repulse the atoms to the minimum place of light field. this is the principle of atomic mirror or atomic guide and trap. in this thesis, we propose three novel mirrors to reflect atoms by using intensity gradient induced by a blue - detuned semi - gaussian laser beam, a blue - detuned semi - ellipse - gaussian laser beam and a blue - detuned semi - flattened - gaussian laser beam
本文提出了三種實現原子束反射的原子反射鏡的新方案： （ 1 ）半束蘭失諧高斯光束的原子反射鏡（ 2 ）半束蘭失諧橢圓高斯光束的原子反射鏡（ 3 ）半束蘭失諧平項高斯光束的原子反射鏡，詳細計算了上述反射鏡的衍射光場的空間分佈，並討論了運動原子在光場中所受的偶極力。
