Our land and naval forces should be moderate, but adequate to the necessary purposes--the former to garrison and preserve our fortifications and to meet the first invasions of a foreign foe, and, while constituting the elements of a greater force, to preserve the science as well as all the necessary implements of war in a state to be brought into activity in the event of war; the latter, retained within the limits proper in a state of peace, might aid in maintaining the neutrality of the United States with dignity in the wars of other powers and in saving the property of their citizens from spoliation.

我国的陆、海军应该规模适度，但又足以应必要之需，前者防守、保卫我们的军事要塞并打退外来敌人的最初入侵，而且，作为一直更强大力量的组成部分，它应使作战技术和所有必要的军事设施处于一旦战争爆发就能投入使用的状态；后者在和平时期保持适当建制，在他国发生战争时，帮助合众国保持由尊严的中立，并保护合众国公民的财产免遭劫掠。

Our land and naval forces should be moderate, but adequate to the necessary purposes the former to garrison and preserve our fortifications and to meet the first invasions of a foreign, and ,while constituting the elements of a greater force, to preserve the science as well as all the necessary implements of war in a state to be brought into activity in the event of war; the latter, retained within the limits proper in a state of peace, might aid in maintaining the neutrality of the United States with dignity in the wars of other powers and in saving the property of their citizens from spoliation. In time of war, with the enlargement of which the great naval resources of the country render it susceptible, and which should be duly fostered in time of peace, it would contribute essentially, both as an auxiliary of defense and as a powerful engine of annoyance, to diminish the calamities of war and to bring the war to a speedy and honorable termination.

我们应保持陆海军的适度规模，但又必须有足够的驻军保卫国界，防御外敌突袭：组成强大军事力量的同时，保护科学和所有必要的一旦发生战争即投入使用的战争工具，后者，在和平时期保持适度，而在其它权利的较量中可维护美国的中立和尊严，捍卫公民财产不受侵犯，战争期间，增大海军规模使它受影响，和平时期它需被充分补偿，作为防卫辅助手段和强大的烦扰机器，它能减少战争灾难，并给战争带来快速而崇高的终止。

Thus, in order to define the subject-object relation, it is imperative to clarify the methodology that has been applied as follows. First, at certain stage of the research, it is necessary to discriminate the parts from the whole; second, when examining the subject-object relation, it is necessary to define the subject and the object from specific perspectives and their mutual relation.

因此，要在理论上搞清楚主体和客体及其关系，从方法论上应有两方面的约定：一是在一定阶段的研究中需将部分从整体中分离出来；二是在考察主体与客体的关系时，需从特定的视角出发确定主客体及其相互关系。

Our results improve the former results. For periodic Jacobi matrix, some new spectral properties of periodic Jacobi matrix are given by studying the relationship of the eigenvalues of periodic Jacobi matrix and its n—1 principal submatrix. Applying these spectral properties, we present a necessary and sufficient condition for the solvability of an inverse problem of periodic Jacobi matrices and discuss the number and the relationship of its solutions. Furthermore, we propose a new algorithm to construct its solution and compare it with the former algorithms. As this inverse problem of periodic Jacobi matrix usually has multiple solutions as many other eigenvalue inverse problems, we study the uniqueness of this problem. And a necessary and sufficient condition is given to ensure its uniqueness, under which an algorithm is presented and the stability analysis is also given. Finally, we put forward a new inverse problem for periodic Jacobi matrix which has not been solved.
