-
A key step to control the size and shape of the growing particle is dynamically to coat the particles with a closed - packed monolayer of coordinating ligand, mercaptosuccinic acid ( msa ). suitable large size nanoparticles ( several tens nanometer ) and nanorods have been made. after size selection, a certain size nanoparticles were assembled into micrometer sizable super lattice crystal
制得的金納米粒子再經過粒經篩選，得到粒徑一定的納米粒子，然後，將其溶解成一定濃度的溶液，並加入一定量的濃鹽酸，製成微米級的自組織結晶體。 -
For details below : 1 ) video changed from mpeg2 ps to mpeg2 ts 2 ) audio of ntsc format that can not be decoded by stb could be changed from dolby acs coding standard to mpeg1 / 2 layerll standard, and packed into mpeg2 ts format 3 ) well synchronized with audio and video by a new arithmetic " successive time stamp " this thesis made a introduction of mpeg2 standard in detail ; discussed the system timing model ; indicated the key during the transforming of video and audio ; especially explain how to deal with the pcr
2 ）針對目前機頂盒不能解碼的ntsc制式dolbyac3編碼演算法音頻信息，轉換成mpeg1 2layer編碼，並打成滿足mpeg2ts語法的信息包。 3 ）提出了能使音視頻達到良好同步的繼承性時間標簽打入演算法本文詳細介紹了mpeg2標準的語法，討論了mpeg2系統的時間模型從而指出視音頻處理中的關鍵，對pcr的處理進行了詳細的分析，提出了新的視、音頻同步演算法。
