相调和的

We've found that on symplectic manifolds there exists a series of Euler-Lagrange cohomology groups different from both de Rham and harmonic cohomology in general and proposed a set of general volume-preserving equations that contain the Hamiltonian equations as a special case.

中文摘要：我们发现在作为经典力学中的相空间的辛流形上有可能存在不同于de Rham上同调和调和形式的上同调，称之为Euler-Lagrange上同调；提出相空间上保体积的一般方程，通常的正则方程是其特殊形式；进而推广了经典力学中著名的刘维定理；同时把Noether定理与上同调联系起来。

Needless to say, the sight of this in congruously attired trio walk in g at such a time and in such a place attracted a certa in amount of attention

Especially, the technology of Automatic Gain Control and signal processing are studied which are key factors working on the performance of the receiver. Based on analyzing the theory of automatic Gain Control, operational amplifiers 0P37 and logarithmic D/Aconverter AD7111A are used to design variable gain amplifiers which can be controlled numerally, A/D convector LTC1405 is Used to test the echo, Complex Programmable Logic device is used for controller, and an arithmetic is designed for automatic Gain Control which is simulated and analyzed in order to test its feasibility.

本文在分析自动增益控制AGC原理的基础上，采用集成运放OP37和数控增益衰减器AD7111A设计可数字控制的可变增益运放模块；采用高速A／D转换器LTC1405作为回波信号检测模块；采用复杂可编程逻辑器件CPLD作为核心控制模块，构成数字自动增益控制电路，并设计粗调和细调步进控制相结合的算法，对回波信号的增益进行精确而快速的调节控制，使回波信号振幅快速稳定在设计指标范围内，利于接收机后续信号处理电路对回波信号作进一步的处理。

When using relative number or average number to get averaging, you may use denominator or numerator of this relative number or average number as weight number to weigh the relative number or average number,and use frequency formula or weighted harmonic mean formula of weighted arithmetic mean formula to get its mean value.

在由相对数或平均数求平均数时，可以以这一相对数或平均数的分母或分子为权数，对这一相对数或平均数进行加权，利用加权算数平均数的频数公式或加权调和平均数公式求其平均值。

They do not know those parts of it which explain and justify the reminder:the considerations which show that a fact which seemingly conflicts with another is reconcilable with it,or that,of two apparently strong reasons,one and not the other ought to be preferred.

他们不了解理论的解释和说明部分，这些部分提醒人们思考：一个事实好像和另外一个事实相冲突但实际上却是可以调和的，或者两个明显都是有着牢固根据的理由，其中一个而不是另一个总该受到人们的青睐。

The yod can be accentuated when an opposition is thrown in, with two semisextile aspects too.

Of the importance of the Square of 8 and 9 grid relationship, Schwaller says, These two lengths, 8 and 9, are related to musical harmony. This is the tone in music and also the ratio between the diameter of a disk and the side of a square of the same surface area. The sum of 8 and 9 is 17, the famous number of Jabir [the famous Arabic alchemist of the 8th century C.E.].

对8方图和9方图的重要关系，古埃及考古学家，金字塔研究专家史沃乐先生说：这两个长度，8和9，和音律和谐规律是相关联的，它们是音乐中的调和与增强，也是一个圆的直径和等面积直角方形的边长的比率。8和9的和等于17，它是一个著名的阿拉伯术士在公元8世纪所使用的一个著名的数字。
