There are two fundamentally different dynamical systems: those with discrete time variable and those with continuous time variable.

本文主要针对离散时间动力系统的动力学性质研究，包括差分方程及离散人工神经网络两个方面的研究。

The control variable is just a normal variable and is accessible to the program just like any other.

控制变量是一个常规的变量其值是可控的就像任何其他程序。

According to induced response method, the expression in frequency domain of pressure response at the end of pipeline is derived using impulse response method and convolution theorem. The expression indicates that that transfer function is only related to the characteristics of pipeline system and the Fourier transform of flow variable only depends on the operating characteristics, and the pressure response in frequency domain is linear with the Fourier transform of flow variable.

基于激励响应法，应用脉冲响应方法和卷积定理得出了管道末端压力响应在频域中的表达式，此式表明：传递函数只与系统的特性相关，流量变量的傅立叶变换只与操作特性相关，且压力频域响应与流量变量的傅立叶变换为线形关系，根据此式在理论上能够得到管道泄漏点的重要信息。

A curve coordinate system which is suitable for variable height curved box-girder were established. The flexure, torsion and distortional warping displacement functions were established, and the strain-deformation equations were obtained, a spatial finite element analysis method of trapeziform cross section variable-curvature box-girder with vertical symmetrical axis was also presented.

建立适合于变高度曲线箱梁的曲线坐标系，推导了变曲率、变高度箱梁弯曲、翘曲扭转和畸变的位移方程和应变-位移关系式，提出了具有一个竖直对称轴的变高度变曲率曲线箱梁的薄壁曲梁空间分析有限元方法。

Based on the flaw of the probability reliability model in the case of small amount of information,non-probability and mixed probability/non-probability reliability models are presented. When the uncertainty of the basic random variable is described by convex, analytical and numerical methods are constructed to calculate the convex of response variable. The infinite norm index, which is the minimal infinite norm distance from original coordinate point to the surface of the limit state in the standard interval space, is presented to measure the safety of the structure.

针对概率可靠性模型在小子样信息下的缺陷，建立了非概率可靠性模型及概率—非概率混合可靠性模型；给出了用集合来描述变量不确定性时，极限状态变量变化集合的解析解和数值迭代解法；提出了物理概念明确且十分易于工程应用的度量结构、机构安全程度的无穷范数指标，它是标准区间空间中坐标原点到极限状态表面的最小无穷范数距离。

To resolve this problem, we'll reel outwards drive across the bridge to the intermediate surface of variable-speed drive wheel with two wheels of processed into 30 °, the increase in friction with Groove, even if such a belt would not have had; the diameter of 6 mm, spin out to o-rubber belt changed out with Burr corn-cob o-shaped belt; crossing the bridge to another variable-speed drive belt pulley to roll out of the book, two rounds of the belt pulley turned into 1/2 inch, using chain drive sprocket, and fixed machinewe side wall to cross the bridge wheel seat side wall plate processing growth holes for adjust tension pulley and sprockets.

为解决这个问题，我们将分切机朝外传动面传动到中间过桥变速皮带轮的两轮加工成30°的带槽，增加摩擦力，这样皮带即使松了也不会打滑；直径6mm的O型橡胶皮带改成外面带毛刺的聚氨酯O型皮带；过桥变速皮带轮的另一个传动到出书辊的皮带轮，两轮改成1/2英寸的链轮，采用链条传动，再将固定在机器侧墙板的过桥轮座侧墙板孔加工成长孔，可任意调整皮带轮与链轮的松紧。

If this value is significant, it means that the independent variable does contribute to the dependent variable.

如果这个值是重要的，那表示因变量受自变量的影响大。

In both types of studies, the effect of differences of an independent variable on the behavior of the dependent variable are observed.

在两种类型的研究，对不同的一个独立的变量的行为的变量得到遵守。

A function is a dependent variable , whose value depends on the value of an independent variable .

The function obtained by expressing the dependent variable of one function as the independent variable of another;''.

用一个函数的自变量表达另一个函数的因变量而得到的函数。

Don not attempt to do something which you can not to do.

不要企图做那些办不到的事情。

The expression of CTGF and TNF-αweredetected by immunochemistry and the number of Clara Cells was calculated.

光镜下观察肺组织的病理变化，采用免疫组化染色观察肺组织中结缔组织生长因子和肿瘤坏死因子-α的表达和Clara细胞的数量。
