Steel frame with welding joint easily occur brittle collapse because of having a low ductility at joints then ， a semi - rigid connected steel frame has large the energy absorption capacity which can resist dynamic loads and the using steel qualities of bracing system and joints are small so adopting a semi - rigid jointed steel frame is economical and stable but for semi - rigid connections are complex and variable ， in conventional analysis and design of steel structures ， it is usually assumed that the connections between columns and beams are either rigid or pinned the analysis of steel frames adopting the assumption can simplify the procedure of analysis and design ， but cannot precisely reflect structural practical circumstance and the errors of calculating results are large ， even ， get incorrect conclusions semi - rigid connection was referred to in chinese code for design of steel structures ( 2001 ， 10 ) ， however ， it isn ’ t specified how to apply semi - rigid joints in design in fact it cannot be carry out the purpose of the paper give a calculating method that accords practical engineering and easily put into effect worthwhile it is going to promote the development of semi - rigid jointed steel frame in design and heighten structural stability in the paper ， at first some commonly employed methods for the modeling of connection behavior are introduced richard abbott function modeling of connection is adopted for extended end plate bolted connection by the 34 test data comparing to regression analysis indicate richard - abbott function modeling of connection represents an excellent fit to test data then after a semi - rigid joint behavior can be modeled as a finite stiffness rotation spring ， base on rotation and displacement equation derive the element stiffness matrixes with semi - rigid connections where the effects ofj ointed flexibility geometric non - linearity and shear forces in the connection deformations have been considered in and fixed - end forces are modified finally, a program for calculating semi - rigid with incremental - iterative method has been
本文的目的就是為半剛性連接鋼框架的設計提供一種既符合工程實際又簡便易行的計算方法，供規范使用過程的補充、延伸或參考；同時，也將促進半剛性連接鋼框架設計技術的發展，為提高結構安全性能、節省工程成本發揮應有的作用。本文首先介紹了常見的幾種應用較為廣泛的樑柱連接彎矩轉角關系模型，在分析比較的基礎上，選用richard ? abbott函數模型作為外伸端板連接彎矩轉角關系模型，通過對34個外伸端板連接的實驗數據與回歸分析得到的參數比較可知，經回歸分析得到的此模型參數與實驗數據符合較好。然後用彈簧表徵連接點的轉動剛度，根據梁的轉角位移方程推導出半剛性連接的剛度矩陣，在單元剛度矩陣中考慮了節點柔性、幾何非線性和剪切變形的影響，並對固端力進行了修正，最後用增量迭代法編制有限元程序進行計算和分析。 -
After the compensation based on the rule of the minimum entropy, the resolution of the cross - range image is lower as the large size and non - uniform rotation, which cause the image to be not right at all sometimes. in order to eliminate effect of the non - stationary rotation, the first order approximation and relax algorithm are adopted to search the initial frequency, amplitude, frequency modulation rate and obtain the dynamic image of the target at any time
分析了低分辯雷達的成像演算法，建立在最小熵補償基礎上的演算法得到的橫向像的解析度仍然比較低，尤其對大的目標和機動目標，為此我們採取了一階近似的relax演算法搜索目標的初始頻率、幅度、解調率從而獲得目標的動態一維像，模擬數據和試驗結果證明該方法是有效的。 -
Based on the experimental results and the correlative chemistry theory, the phases formed in the process and its influenceable factors were studied. the significant results were enumerated as follows : as for the mn - h2o system, 5g pure mn scraps ( 99. 5 %, - 200mesh ) and distilled water served as the starting materials were milled by high energy ball miller together with 200g steel balls as the milling medium. the experiments were conducted with the rotation speed of 380rpm. - mn3o4 nanopowders were fabricated after milling some time and would experienced phase transformations if continue to be milled. the reaction would be accelerated if a little of hcl or mnso4 was added while be decelerated if. a little of naoh was added. the - mn3o4 phase with particl size between 20 ~ 100 nanometer was obtained after milling 1. 5h when trace hcl was added. the oxygen added to the ball tin has little effect on the reaction
主要實驗結果如下: （ 1 ）對于mn - h2o系，通過高能行星式球磨機，在50ml蒸餾水中球磨5gmn粉末，球料比為40 : 1 ，轉速為380rpm ，球磨一定時間后獲得了納米級單相- mn3o4 。隨著球磨時間的延長，生成的- mn3o4會繼續被氧化或發生晶型轉變。加入微量hcl或mnso4會明顯加快mn的反應，加入hcl后，球磨1 . 5h后即獲得粒徑為20 100nm的單相- mn3o4粉末;加入微量的naoh會抑制mn反應生成- mn3o4 。
