  2. At the conditions with the same fuel injection quantity per cycle and the same engine speed, with the increase of the additive mass fraction in the fuel, the ignition and heat release timings brought forward, the peak of heat release rate increased and the operating range at low engine load was enlarged obviously. however, excessive additives will make the engine be prone to knock, run rudely and shorten the operating range at high engine load

    在相同循環噴油量和相同轉速的條件下，隨著添加劑質量分數的增加， hcci著火和燃燒放熱提前，燃燒放熱峰值提高，低負荷工況范圍明顯拓寬，但過高的添加劑質量分數會使得發動機爆震，工作粗暴，導致高負荷工況變窄。
  3. This paper confirms a kind of non - linear mapping relation between vibration velocity of particles on building and the influence factors, such as total explosive charge, maximum explosive charge fired at the same time, the distance between blasting point and monitoring points, peak particle velocity of ground where building is, the height from monitoring point to ground, and so on, and sets up a support vector machine ( svm ) model for forecasting the vibration effect induced by an explosion

    應用支持向量機，建立了總藥量、最大段藥量、爆破點與監測點距離、構築物所在地面震動峰值速度、測點到地面的高度等因素與建築物上的質點震動速度之間的非線性映射關系，確立了支持向量機預測模型。
  4. Non - uniformity of the amplifying effect and dimension of the slope are pointed out through analysis of the distribution of the stress and sonic speed in the slope. forms of slope lost stability resulted from blasting vibration are analyzed and appraising rules of slope stability are summarized by a great deal instances on coasts. based on general discussion about calculation methods of the slope stability under the effect of blasting vibration, the synthetical method, a new one, is put forward, analyzed through a sample by and pointed out which is one of most valid methods

    利用波動理論，得出延期時間為nt / m時減震效果最好；在分析邊坡巖體內部應力、質點速度等分佈規律的基礎上，指出邊坡震動放大效應的不均勻性和邊坡尺寸效應；結合大量滑坡實例，分析了爆破震動引起邊坡失穩破壞的幾種形式，總結出邊坡穩定性評價準則；基於對邊坡穩定性計算方法的綜合分析，提出了一種綜合分析方法，通過算例計算分析，證明該法計算精確度高、功能全面，是邊坡動力穩定性分析的有效方法之一。
