If air resistance is neglected, and the speed of the object is measured over several short, consecutive intervals as it falls, the differences in the speed of the object can be used to determine the acceleration due to gravity.

如果忽略空气阻力，并在几个短暂、连续的时间间隔上测量物体的速度，就可以用物体速度的微分来计算重力加速度。

You want to define methods in an object, and be able to access them without instantiating a object.

你想要定义方法在一个对象。然后可以访问它们在没有示例的对象

To express the object semantics efficiently, the structure of ANGEL complex object is represented as an indexed n-ary tree in the secondary memory, while in the main memory, it's represented as a directed acyclic graph.

为有效表达对象语义，ANGEL的复杂对象结构在外存中表现为带索引的多叉树，在内存中则表现为有向无环图。

From the theory, the algorithm for determination of the degree of implicit polynomials is followed: detecting the stationary points in the object boundary based on its features, and then calculating the minimum degree according to the formula derived from the theorem. In addition, the theory can be extended to three-dimensional object.

该方法首先由给定物体边界的轮廓检测出其驻点数，然后根据驻点数得到拟合隐含多项式曲线方程次数的下界，进而推广到三维物体的隐含多项式曲面拟合次数的确定。

Through the introduction of the adjacent object direction angle and shielding angle,the ultimate adjacent objects are identified close to the direction of the adjacent object mask.

通过引入相邻对象方向角和屏蔽角，对方向接近的相邻对象进行屏蔽，实现对确定相邻对象方法的改进。

It developed for military affairs first in Occident .It utilizes the characteristic of NUV spectrum (240-280nm) that UV spectrum of object is much greater than that of solar radialization in the aerosphere. Double spectrums imaging system gets UV and visible images to identify the object and background. Image infusion is a essential step of succedent image processing.

它利用中紫外区的"日盲"(240—280nm的中紫外)特性，即目标发出的紫外线远远强于太阳的紫外辐射，通过双光谱图像检测系统观察和检测该波段的紫外目标信号与背景可见光图像，并利用图像配准与融合技术，把紫外光图像准确地定位于背景图像，形成合成图像达到检测目的。

In his opinion: freedom in modern society is a kind of inter-control relationship between human and objects, that is an illusion of freedom; personality is the outcome of the batch production of consumer system; it is a kind of self-shoot, a shadowy self-comfort and satisfaction; the aesthetic distance formed the lonely state of modern human, this makes favor and identity be important motivity of consumption; nature here has been changed to naturety, it is a consumable symbol opposes to real nature; art and artworks gradually turns into sign; as the container and carrier of spirit, body has been changed to a separate object, a kind of capital that needs to be managed and operated; the inimitably expansion of image in mass media make human immerse in the aspiration of itself, which makes human fowardly go into the matrix of consumption.Abundant objects and information are accumulated in supermarkets and mass media, which give people an image of rich. At the same time, commodity appears in series to rise people's desire. The difference between kinds of commodity has gradually been erased, replacing the utility as object.

他认为：当代的自由实际上是人与物的相互操控关系，是人的自由幻觉；个性是消费系统中批量生产的产物，是一种自恋性的投射，一种虚幻的自我安慰和满足；审美距离则造成了当代人的孤独，这使得关切和身份认同成为消费的重要动力；自然已经变成自然性，成为对立于真正自然的可消费的文化符号；文艺复兴以来的艺术和艺术品逐渐由模仿转为表现再转为符号。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor".
