  1. To often be in " force empty season " ( see add civil " why does soybean futures appear easily force storehouse " ) suffer losing nominal for, corresponding strategy is through moving the storehouse comes the time of protracted complete a business transaction ( displacement reachs basic admiral storehouse annual 11, 1, march agreement, but, as a result of 1, agreement traded in march scale is not large, move commonly the main target that the storehouse operates was november agreement ), reduce the still can achieve make up the deficits and get surpluses even goal of the loss

    對于經常在「逼空季節」 （見附文「大豆期貨為何輕易出現逼倉」 ）遭受損失的空頭來說，相應的策略是通過移倉來拖延交割的時間（基本上將倉位移至每年的11 、 1 、 3月合約，但是，由於1 、 3月合約交易規模不大，一般移倉操作的主要對象是11月合約） ，降低損失之餘甚至還能實現扭虧為盈的目的。
  2. And the best scheme among them has been proposed. in the last, with design opt of ansys, assigning roof plate ' s and base plate ' s thickness as design variables, making them meet the constraints of displacement of roof plate and base plate, and assigning the maximum stress of the structure as the goal function, the pile - boots structure has been optimized

    最後利用ansys自帶的優化求解器designopt ，以對樁靴結構強度和變形影響較大的頂板和底板厚度為設計變量，在滿足重要部件?頂板和底板豎向位移的約束條件下，把結構的最大等效應力設為目標函數，採用一階優化方法，對樁靴結構進行了優化設計，並得到了最優解。
  3. According to feature that goal function has more than one local extremum in displacement back analysis for underground engineering, a new means of displacement back analysis for underground engineering has been established through adopting fem and self - adaptation idea on the basis of the improvement of the determining method of control parameters, such as initial temperature and number of state choice and annealing strategy, moreover, the relevant analytic software is developed

    摘要本文針對地下工程圍巖位移反分析問題的目標函數存在多個局部極值的特點，在對模擬退火演算法進程中控制參數，即初始溫度、每一溫度下的狀態選取次數和退火策略的確定方法加以改進的基礎上，引進有限元分析手段和自適應的思想，建立了基於改進模擬退火演算法的位移反分析方法，並開發了相應的分析程序。
