In section 2. 2, we prove that if the set of arrows in a quiver is not empty, then nq is not semisimple. we construct the nonsovable subalgebra of nq when there is no less than one circle whose length is bigger than one, and there is no loop in quiver q, thus leads to a conclusion that nq is nonsovable. using the index arrays to discuss the operation of necklace word. construct a sovable subalgebra of nq, which is not nilpotent. this shows that nq is not nilpotent provided that there is a cyclic with length bigger than 1
當箭圖中有長度大於1的循環，且無圈時，構造了n _ q的非可解子代數，從而證明了n _ q是不可解李代數。我們還利用指標數組討論了項鏈字的運算，構造了n _ q的可解非冪零子代數，從而證明了當箭圖中有長度大於1的循環時，項鏈李代數非冪零。在2 -
Behavior and mechanism of concrete filled double - skin steel tubular ( cfdst ) beam - columns subjected to monotonic or cyclic loading were investigated. two kinds of cfdst section tubes were studied in this paper, that is, the outer steel tubes are circular hollow sections ( chs ) or square hollow sections ( shs ), while all the inner steel tubes are chs. based on systematic parameter analysis, simplified models were derived to predict the load - carrying capacities of the composite members, and simplified moment - curvature and lateral load - lateral deflection hysteretic models, as well as ductility coefficient were suggested
