draft pole-
Recently, a new gene dr0167 ( pprl or irre ) that serves as a general switch for downstream dna repair and protection pathways via its regulatory function on the gene expression of reca, ppra was discoveried. expression of d. radiodurans pprl also promotes dna repair and protection pathways and enhances the radioresistance of e. coli. this finding provides a new clue to understand the mechanism of dna repair, especially double strand break ( dsb ) repair
最近我們實驗室在耐輻射球菌電離輻射敏感株中鑒定了一個與電離輻射抗性相關的基因ppri ，該基因可能通過調控dr細菌reca 、 ppra等基因的表達加速對電離輻射引起的dna損傷修復，而在大腸桿菌中表達ppri基因能促進reca 、 soda等表達水平顯著提高，使其抗輻射和抗氧化能力明顯增強，這將為我們理解其特殊抗性機制，特別是雙鏈斷裂修復提供新的線索。Based on the principle of the force density method, a new shape finding method for the solution of this special problem is developed
該方法不受結構形式的限制，且引入了很少的計算假定，能夠解決不同形式的索桿張力結構施工過程的形態分析問題。3 ) based upon analyzing the variation laws of bridge ’ s dynamic features, it is proposed in this paper that structure frequency and mode of vibration should not be used as the “ dynamic index ” of cable force dynamic evaluation, because the variation of structure frequency and mode of vibration resulting from tie bars ’ loss is very small
3 ）在分析系桿截面損失時橋梁整體結構的動力特性變化規律的基礎上，指出系桿損失引起的整體結構頻率及振型的變化很小，不宜作為索力動態評估的「動力指紋」 。The task consider geometry stiff matrix of suspenders due to adjustment of suspender length ( the actual suspender length is shorter than its nominal length ), and derive method and step of static tension of suspenders from single order variation
本課題還考慮了由於吊索（桿）長度的調整（實際的吊索（桿）長度比名義長度短）而引入的吊索（桿）系的幾何剛度矩陣（初應力剛度矩陣） 。分享友人
