In 1997,Their infinite-dimensional dissipativity wasfurther studied by Hill,who also studied the finite-dimensional and infinite-dimensionaldissipativity of one-leg methods.However,up to now,no papers have been concernedwith the dissipativity of delay dynamical systems and their numerical solutions.Thethird part of the thesis is devoted to discussing it.

当用数值方法求解这些系统时，自然希望数值方法能保持系统的该重要特性。1994年，Humphries和Stuart首次研究了Runge-Kutta方法对有限维系统的散逸性。1997年Hill进一步研究了Runge-Kutta方法的无穷维散逸性和单支方法的有限维和无穷维散逸性。

摘要牵引式全环面无限变速器是采用转矩分流方法，把全环面可变耦合器与行星齿轮机构及定速比齿轮机构结合起来，其减速比可以达到正无穷和负无穷，即变速时输出轴可以由正转经零转到反转，因而命名为无限变速器(Infinitely Variable Transmission，简称IVT)。

The Infinite is not a bankrupt and we who are the representatives of Infinite power should not be bankrupts either, and if we wish to be of service to others we must have power and more power, but to get it we must give it; we must be of service.

无限意味著永远不会破产，而我们作为无限能量的代言人，自然也不应以破产的面貌出现，如果我们希望对他人有所帮助，我们首先自己要拥有能量，多多益善。然而，欲有所取，必有所予，我们必须对他人有所帮助。

For the problem of the ratio of inner to outer diameter of long tube, according to the "residual core" in the target plays an important role in DOP of long tube penetrator, the analytical model of long tube pentration in semi-infinite homogeneous steel target is established and calculated to devide three kinds of different scopes, the rule of varied by the ratio of inner to outer diameter is analyzed. The patterns of penetration of the yawed tubular against a normal homogeneous semi-infinite target is established, the size and direction of "residual core" is analyzed, under the different impact yawed, the regularity of variations in the yawed of the tube and depth of the penetrateion is described during the penetrateion against the plate.

二是对于长管体的不同内外径比，依据长管体时形成的中间&靶芯&是其侵彻机理不同于长杆体的重要因素，分三种情况建立了长管体对半无限均质靶板的简化理论模型，并进行了分析，得出了穿深随内外径比变化的规律；描述了带攻角长管体垂直侵彻半无限厚靶的物理图像，分析了&靶芯&力的大小和方向，建立了侵彻简化模型，给出了在不同的初始攻角条件下，管体在侵彻过程中攻角和穿深的变化规律。
