Most people consider the return current when considering a fully differential circuit, but when considering the more usual circuit where a signal is referred to 'ground' it is common to assume that all the points on the circuit diagram where the ground symbol is to be found are at the same potential.

分析差分电路时，绝大多数工程师都会注意到返回电流，但对于常见的所谓单端电路，即所有信号采用相同参考点的电路，往往会认为电路中所有标有参考点符号的地方电平都相等。

For higher codimension, the situation becomes more complicated. Due to the counterexample of Lawson-Osserman [31], the higher codimension Bernstein type result is not expected to be true in the most generality.

在余维数为1的情况，这个结果以被推广到(n+1)-维欧氏空间中(n≤7)，以及在某种增长性限制下，这个结果被推广到任意维数欧氏空间中，这些结果可以参考[17]及其参考文献中所提到的文献。

The basic concept and characteristics of missile system-of systems combat simulation for effectiveness evaluation were summarized and the problems of simulation model specification were analyzed, then the hierarchical description and composition method based on system-of-systems, entity and behavior was proposed as the modeling methodology of system-of-systems combat simulation, which is SEB composable modeling methodology. Then, the reference model of SEB methodology and the modeling reference view of various hierarchies were discussed.

As to the remaining parameters, two methods are developed: first, accepting that the projection function complies with a circular function within at least a part of a given field of view, constrained by the obtained object-to-image radial mapping and a constant focal length, the best-fitting point of the optical origin is tested along the optical axis; secondly, referring to the postulation of the exclusively bilateral mapping between an imaged point and its scenic sight ray, a measuring technique is developed to survey the world coordinates which will fabricate a projecting path to the imaged points located on the imageable region of the image plane in order to directly model the projection geometries involved.

而针对其余参数本文提出两种解题方法：其一是根据『在「部分视野角范围」内，鱼眼相机的投射模型符合一典型的「圆形函数」』以标靶实体与其影像尺寸为限制条件，测试光学轴上的最佳视觉参考点、鉴定最适当的投射模型、焦距、及有效的视野角度范围。其二是根据『一视野线排他性地与对应「呈影点」一一映射』参考一呈影点来搜寻空间中对应视野线的绝对座标后，据以演绎相机内部影像形成的模型。

First, on the basis of the theory of fairness and efficiency in tax, expense deducting is analyzed referring to the juristic principle, which provides theoretical basis and reference for the adjustment in expense deducting system. Second, by the method of induction and comparing, the author analyzes and introduces the expense deducting system in other countries or regions. Third, defects which exist in current expense deducting system of individual income tax are demonstrated. At last, connected to the reform of patterns of individual income tax, relative suggestions regarding to the adjustment of expense deducting system in our country are put forward, which is adopting mixed tax jurisdiction. The two patterns of family tax and individual tax exist at the same time and family tax should be prevailing. These two patterns can be chosen by taxpayer voluntarily. Referring to the methods in other countries and regions, the items and standard of expense deducting of individual income tax should be improved.

首先以税收的公平和效率理论为基础，结合税收扣除的法律原则，对费用扣除进行分析，为我国的费用扣除制度调整提供了理论依据及参考；其次，运用归纳比较的方法，对国外的费用扣除制度进行了分析介绍；再次，论证了我国现行个人所得税费用扣除制度存在的缺陷；最后，本文结合个税税制模式的改革，提出调整我国费用扣除制度的相关建议：实行混合制；选择家庭课税和个人课税并存的模式，以家庭课税为主，由纳税人纳税时自愿选择；参考国外的做法，完善个人所得税费用扣除项目及标准。

Results The behavioral features of the aged learning and memory impaired rats were as follow: 1 There was little change happened to the sample performance. 2 The spatial reference memory had obviously declined. The swimming times of searching the hidden platform in the place discrimination performance, the swimming time in a 40cm annulus at the primary platform place (A40T) and the platform crossings in the probe trial performance were the most suitable indexes for mirroring the spatial reference memory abilities. 3 The spatial working memory had not decreased so clearly.
