  1. The concept of the optimize design is proposed and its mathematic foundation is analyzed in this paper. after comparing several optical calculation methods, the one that is suitable for the lubricating system is chosen and analyzed in detail about its concept, characteristic and some focal points. meanwhile, combining with the analysis of the relationship among the parts and structure of marine low - speed diesel lubricating system, the internal disciplinary, other pipeline system and main engine, aiming at reducing the initial investment and the running cost in a certain years, the mathematic model of the system is built and the object function and subjected conditions are set up

    本課題闡述了最優化設計的概念，分析了最優化設計問題的數學基礎，比較了約束多維問題的幾種優化方法，選取了適合於潤滑油系統的優化設計方式，並對該方式的概念、特點及其應注意的問題進行了較詳細的分析；同時，結合海船低速柴油機潤滑油系統的組成部件及其結構以及潤滑油系統內部規律與其它管路系統、船舶主機的關系的分析，從經濟性的角度，以設備初投資及其在一定年限內的耗能費最低為目標，建立了本系統優化設計的數學模型，確立了目標函數和約束條件。
  2. In addition, effects of several factors such as local site conditions, focal mechanism, epicentral distance and seismic magnitude on these parameters are discussed, and several significative results and conclusions are obtained. in all records there are about 1 / 3 vertical ground motion ’ s peak acceleration bigger than 2 / 3 of the corresponding horizontal one, so the action of vertical ground motion should not to be underestimated. vertical design response spectrum equals that the horizontal design response spectra times 65 % is probably unsafe when period is short, and suggest adopting different coefficients when at different periods

    本文基於對大量歐洲強震記錄的研究，分析了地震動豎向與水平向分量在峰值加速度、反應譜值、頻譜周期等參數方面的差異，以及這些參數與場地、震源機制、震級和震中距的關系，得到了以下有意義的結果和結論:在本文分析的地震記錄中大約1 / 3的記錄加速度峰值比大於2 / 3 ，豎向地震動分量的作用不可低估;在短周期，豎向地震動影響系數的最大值僅取為水平向地震動影響系數最大值的65 %是偏於不安全的，可以考慮按周期分段採用不同的折減系數;我國現行抗震規范中設計反應譜特徵周期的取值偏低，可能是偏於不安全的;豎向與水平向地震動分量卓越周期的比值在0 . 7 - 0 . 9之間，豎向設計反應譜的特徵周期應有單獨規定。

    運用cabello的邏輯方法論證兩個自旋1 2粒子系統的非定域關聯性質，考察了不同情況下兩個量子位純態的不同態坍縮效應所導致的各個可觀測量之間的量子關聯幾率。
  4. Based on a thorough literature review of researches in sihuan system, approaching from digging emphatically for the progressive merits and practical values of the system, this article probes into several disputed focal topics as follows : how to comprehend and grasp the conditions of applying sihuan, the conditions and timing of breaking down sihuan and executing the death penalty, how to deal with the so called conflict of committing intentional crime and having significant good deeds during the probation of sihuan, and so on

    本文通過梳理有關死緩制度專題研究文獻資料，著重挖掘死緩制度中所蘊含的現代刑罰思想中的進步意義和實踐價值，主要對以下幾個爭議較大的焦點問題進行細致的探討:如何理解把握適用死緩的條件、死緩變更執行死刑的條件、時間以及在死緩期間既有故意犯罪又有重大立功表現的情況如何處理等等。
