  2. In the first part, the basic knowledge of particle scattering in meteorology and physics was introduced. the particles to be discussed include aerosol particles, fog droplets and raindrops and the em wave band in the discussion is near - infrared. in the second part, the mie theory was briefly reviewed and was applied to investigate the scattering characteristics of spherical atmospheric particles, the result shows that in the visibility measurement meter using forward - scattering method, when the working wavelegth is between 0. 8 m ~ 2 m, the scattering angle is between 25 ~ 40, the distinguishability and the relative scattering intensity would be better than those under other conditions. in the third part, the superellipsoid was used to describe a wide range of shapes such as spheres. ellipsoids and cylinders. an improved t - matrix method which can be used to calculate arbitry shaped particle ' s scattering field was introduced, and the scattering characteristics of non - spherical atmospheric particles was investigated with this method

    計算結果表明，從相對散射強度、同一方向上不同粒子散射的可區分程度來看，在散射式能見度探測儀器中，工作波長介於0 . 86 m 2 m ，探測角度選取前向25度40度時，探測的結果將會是比較理想的。第三部分中，使用超橢球方程來統一描述各種非球形粒子的形狀，然後使用t矩陣方法計算了一些形狀的非球形粒子的近紅外散射特性。另外，在本文中還針對球形粒子的散射場提供了一種三維可視化方法，使對散射場強度的空間分佈的理解更加簡單，直觀。
  3. Besides, scan rate and cycle period also affect the result ; co - deposition of dualistic oxide is a focus of research, as an element in the same group, ir is selected. deposition rate of composition is decreased by the adding of ir composition, and when the proportion of ir exceeded 50 %, composition procession can be ceased. but cooperation of ir and ru oxide can highly increase the specific capacitance of active material ; annealing treatment under a certain temperature can help to change the hydrate ru composition into mixture state ru oxide, accordingly increase the stabilization of active material

    研究表明:電解液的配製過程中，氯化釕濃度、溶液ph值、陳化時間、溶液溫度對電鍍效果均有影響，其中溶液ph值是最主要的影響因素;在儀器的使用條件探索中，理論結合實驗確定了本電鍍液體系循環伏安電勢窗的理想范圍，並發現循環伏安掃描速度和掃描周期對電鍍結果也有較大影響;混合氧化物的共沉澱是目前研究熱點，在此選用與釕同一族的銥作為共沉澱元素，銥的加入會阻礙氧化物的沉積速度，銥的比例超過50 %會使沉積作用停止，但是二元氧化物的協同作用使沉積的活性物質比容量大大提高;一定溫度下退火后處理作用會使水合釕化物轉變成混合價態的氧化釕，從而提高活性物質的穩定性。
  4. The thesis also introduces the virtual instrument ’ s concept, system architecture, etc. the development of virtual instrument ’ s application software is discussed in detail. it includes virtual instrument software architecture ( visa ), and virtual instrument ’ s software platforms. the thesis discusses the principle and mechanism of work of the simulation of embedded system. by comparing with the principle of traditional logical analyzer, it draw a conclusion that the virtual logical analyzer will work in synchronous way when it is used for both logical state analyzer and logical time analyzer. the thesis

    論文接著探討了嵌入式模擬平臺的原理和工作機制，通過與傳統邏輯分析儀原理的比較，得出了嵌入式模擬平臺下邏輯分析儀無論是做定時分析，還是做狀態分析都工作在同步方式下;並重點剖析了探頭原理，采樣定理和毛刺，數據的建立和保持時間等邏輯分析儀的重要技術指標，得出了虛擬環境對虛擬邏輯分析儀的功能和各項技術指標的影響，還提出了流水線狀態表的思想和實現機制。
