  1. Most damage of construction is due to the crack, so people always consider the beginning of crack as the sign of danger, it always makes people fear. with the development of economy in our country, the dimensions of construction is larger and larger, and the engineering is growing towards large - scale and complexity, because the refresh of material of concrete, the strength of concrete is improved, but a lot of crack appears in the engineering. in recent years, as the further development of economy in our country, the need of steel in the engineering is increscent, but the supply of steel in our country can not satisfy with the need, the price of steel is continuously rising, so it gives us a problem, we must save steel in designing construction and simultanentily controlling the crack of construction. so it gives us a new question on crack study

    由於建築物的破壞往往始於裂縫,所以人們一般把裂縫的出現視作危險的徵兆,裂縫使人們產生恐懼感。隨著國家經濟的發展,工程建設規模越來越大,工程結構朝著大型化、復雜化的方向進展,隨著混凝土原材料的不斷更新,混凝土強度等級的不斷提高,在實際工程上出現了大量的裂縫問題。近年來隨著國家經濟的進一步發展,用於工程建設的用鋼量日趨增大,而國家的鋼材供應量不能滿足日趨增大的市場需求量,導致鋼材的價格不斷上漲,這就要求我們在節約鋼材用量的基礎上來設計控制工程中的裂縫問題,這也就給裂縫研究提出新的課題。
  2. According to the requirements to pd pattern auto - recognition, this paper studies systematically the basic theories and realizable methods for auto - recognition of pd gray intensity image : ( 1 ) in the requirement of on - line pd monitoring for transformer, several discharge models are designed and the relevant experiment methods projected. with discharge model tests, a lot of discharge sample data is acquired. on the base of systematical research on recognition for pd gray intensity image, this paper puts forward two kinds of fractal features, the 2nd generalized dimensions of original pd images and fractal dimensions of high gray intensity pd images, and then the relevant extraction methods

    針對局部放電模式自動識別的需要,作者系統地研究了局部放電灰度圖像自動識別中的基本理論和實現方法: ( 1 )根據變壓器局部放電在線監測的要求,設計了放電模型和實驗方法,並通過模型實驗獲得了大量放電樣本數據,為構造局部放電灰度圖像和採用bpnn進行識別作好準備; ( 2 )研究了局部放電灰度圖像的構造方法以及降維構造32 32灰度和矩陣的方法;在用人工神經網路對局部放電進行模式識別時,分析了bp網路的優缺點,對典型bp網路的結構和學習訓練演算法提出了改進,採用帶有偏差單元的遞歸神經網路作為模式分類器;採用32 32灰度和矩陣進行bpnn識別結果表明這種方法是有效的。
  3. Influences of two dimensions of head teacher style on eight respects differ a lot at the individual level, the influence of the " cooperate - opposition " dimensionality is greater than that on " dominate - submissive " dimension for physical appearance, general - school, reading, parent relation, and mathematics
