  2. Due to the short distance among the planes which fly in a group, the conventional low resolution radar can not distinguish them in both distance and azimuth ? if we use the technology of isar to resolve the difference among doppler frequency of the targets and obtain a fine resolution cross - cross image, we may separate them, but a long time of coherent processing is needed <, for the formation targets, it can be approximately divided to rigid body and nonrigid body, so for the formation targets, that can be regarded as rigid which has a relative position and an identical movement, can be approximately considered as a large target, and be compensated by translational phase with the rule of minimum entropy, but for the most those cannot accord with the approximation of rigid, being the doppler - frequency of the aim is linear changed, by the relax method with short data, increases the resolving performance of multiple target to the aim in the frequency domain, since cross - range resolution is based on the accumulative time, so it is greatly improve the resolution to formation targets by the instant cross - range image which produced by radon - wigner transformation

    低分辨isan成像及干涉技術應用研究一因此直接無法分辨編隊目標的架數，我們借鑒isar的技術，通過較長時間的相干積累，在多普勒頻域上對目標進行分辨。而對于編隊目標，可分為近似剛性的多目標和非剛性的多目標，所以對于可以近似為剛體的編隊目標相對位置固定，運動方式一致，可以近似看作一個大目標，採用最小墑準則對平動相位的進行補償，但是大多數並不滿足剛體近似的編隊目標，由於目標在相干積累時間的多普勒頻率近似呈線性變化，通過對較短數據利用relax的時頻分析方法，提高了頻率域上目標分辨的性能。由於橫向解析度取塊于橫向積累時間，所以利用radnwigner變換得到瞬時的一維橫向距離像大大提高了對編隊目標的分辨，對模擬和實測數據的大量分析結果表明此方法的有效性和可行。

  4. Then we use shuowenjiezi as well as the three standard books of chinese characters in tang dynasty, ganluzishu, wujingwenzi, jiujingziyang, as the criterion to correct the wrongly written characters, and divide the compiled common chinese words into seven categories : simplify the font, complicate the font, change the strokes, change the goujian, alternate the yifu or yinfu, alter the structure and kuaihuacaoshu. on the basis of that, we illustrate with the quantified data connected with the specifically speaking method that in the seven categories only two categories which are alter the yifu or yinfu and alter the structure maintain the reason of the standard form of chinese characters, the category of complicate the font weaken the reason, and the other four categories destroy the reason. through this, we can see that the reason of the common chinese words is much weaker than that of the standard form of chinese characters, so the common words are mostly excluded by the standard form system and are gradually obsoleted

    本文以《吐魯番出土文書》為材料，採用窮盡式的方法輯錄其中的俗字（以字種數計） ，以《說文解字》以及《干祿字書》 、 《五經文字》 、 《九經字樣》三種唐代正字書作為正字標準，將所輯錄的俗字分為簡化字形、繁化字形、改換筆畫、改換構件、更替意音、變換結構、楷化草書七種類型，並進一步以量化數據和具體分析相結合的方法說明七類俗字中保持正字理據的僅更替意音、變換結構兩類，繁化字形類弱化了正字理據性，其他四類則破壞了正字的理據，說明俗字的理據性要比正字弱的多，因而俗字多被正字系統所排斥，逐漸被淘汰。
