  2. These characteristics and phenomenons have effect on the quality of gear pump, and it is difficult relatively to research them by theory. at present the research is limited to the phase of examination testing. theoretic research of the characteristics and the phenomenons of polymer gear pump are blank in china when the gear pump feeds the viscous polymer liquid of chemical flow with high temperature and high pressure

    齒輪泵除具有流量和容積效率、扭矩和機械效率、功率和總效率等基本特性外,還存在著困油、噪聲和氣穴等現象,這些特性和現象直接影響齒輪泵的質量,對斜齒齒輪泵的這些特性和現象的理論研究較大,目前大多仍局限於實試研究階段,而聚合物齒輪泵在輸送化工流程中的高溫、高壓的粘流態聚合物時特性的理論研究在國內基本還處于空白。
  3. Since high performance control logics are usually hard for non - scan test generation, dft structures could be embedded as offsets in tradition, while it will cause manufacturing cost increase and performance overhead. in this paper, an indirect test generation method based on retiming is proposed, which could dramatically reduce the cost of non - scan atpg without any loss of original optimized attributes. experiments on some iscas 89 benchmarks show the benefits of our approach in enhancing atpg of performance - driven logic

    對性能驅動控制邏輯進行試生成較大,通常要加入可性結構,但會影響原電路優化性能並增加生產成本.本文以重定時理論為基礎,提出了對高性能時序電路進行間接試生成的方法,這種方法在不影響原電路任何優化特性的前提下,可顯著降低試生成時間,提高試生成質量.在iscas 』 89部分基準電路進行實,結果證明了其有效性
  4. ( 2 ) because of t he variability of rock subjected to outside action, three new conceptions : postive damage basic damage and negative damage, are suggested, which can deal with the condition that rock density became large. ( 3 ) the present damage variables based on ct number mostly include ct average number of the rock without damage, which is difficult to measure, so a new damage variable, which includes the average ct number is proposed, on the other hand, strain equal theory is generalized because the one put foreword by lemaitre is not good enough to use. ( 4 ) a axial damage constitutive equation is proposed and testified. ( 5 ) with the circle times, the damage propagation laws of two different rocks, subjected to circle of freezing and thawing, are studied, and in the analysis process, traditional analysis method including average ct number and is used, some important conclusions are reached : inner damage of soft rock containing a large mount of apertures is largely propagating with the time increasement of circle, however, at the preliminary time, the hard rock containing a small mount of aperture is a little propagating, at late time, the influence become large ; ( 6 ) zone separation and statistics frequency put forward is used to analysized the three different damage propagation in the open circumstance, when they are subjected to the different circle times of freezing and thawing, in which the temperature variability is linear, different freezing rate, and different freezing temperature, and no water is supplied during the test

    在研究過程中本文主要做了以下工作: ( 1 )針對巖石損傷變化較小時,運用ct均值和方差分析不方便的缺陷,本文提出運用對ct數范圍劃分區段的方法,根據各區段統計頻率的變化規律來分析損傷擴展狀況; ( 2 )針對巖石受到外部作用的多變性,本文提出了基準損傷,正損傷,負損傷的概念,在某種程上考慮了巖石受到外部作用時的壓密情況; ( 3 )現有的基於ct數的損傷變量大多需要用到巖石基體的ct均值,這實際上是很到的,因此本文建議了一個可運用巖石初始狀態ct均值的損傷變量,由於現有的勒邁特教授應變等價原理使用上的不便,本文在其基礎上進行了推廣; ( 4 )建議了一個可用巖石初始狀態ct數和彈性模量的單軸損傷本構方程,並用算例進行了證; ( 5 )對兩種不同巖石在開放環境下受到凍融循環作用且融化過程中補水時,內部損傷隨凍融循環次數增加的擴展規律進行了探討,主要運用了常規的ct均值和ct方差的分析方法進行分析,試發現:對于孔隙率和含水率較高,密和強較低的軟弱巖石,凍融循環次數對損傷結構的擴展有明顯的影響,而對于孔隙率和含水率較低,密和強較高的硬巖,凍融循環次數對其損傷結構擴展初期由於含水率低的原因,影響不是太大,而後期由於水補給后,含水率較高的原因,凍融影響逐漸增大; ( 6 )運用了本文提出的區段劃分和統計頻率的方法,深入地分析了開放環境下的線性溫變化的凍融循環次數,凍結溫,凍結速不同巖石作用時,其內部損傷隨凍融循環次數,凍結速和凍結溫變化的擴展規律,需要指出的是除了在試前飽水外,凍融過程中沒有補水。
