The first proposes that any differentiable function defined on an interval has a mean value, at which a tangent line is parallel to the line connecting the endpoints of the function's graph on that interval.

第一个定理指出，定义在一个区间上的任何可微分的函数都有一个平均值，在该点的切线与该区间上函数曲线两端的联机平行。

We can take Fourier transformation or Laplace transformation towards try to of square distance both ends according to the their lines property, differential calculus property and integral calculus property, its conversion for act for of elephant function square distance, from this algebra square the distance beg an elephant function, then take Fourier negative transformation or Laplace negative transformation have to originally square distance of solution.

我们可以根据他们的线性性质，微分性质和积分性质，对欲求的方程两端取Fourier变换或Laplace变换，将其转化为象函数的代理方程，由这个代数方程求出象函数，然后再取Fourier逆变换或Laplace逆变换就得出原来方程的解。

The doctor blade gap is set with an accuracy of 0.02 mm by two precision ball-screw stepper-motors,one on each side of the doctor blade.

刀片间的距离的精确度达0.02毫米，这是由位于刀片两端的两个精制球状螺钮步进电机来确定的。

This paper introduced the use of differential pressure meters which use a double cone as the primary differential pressure producer.

美国的煤层气生产者在煤层气计量方面面临的挑战主要包括：在煤层气井口进行准确的气体流量测量的同时，在测量系统的两端要保持一个低的差压值；要妥善处理流量计测量管段中的湿气体问题等。

Fixed occasional double pulley block fixed at both ends by bearings.

复式托带轮固定轴两端由轴承座固定。

This paper introduced an eigen-mode decomposing method to decouple zero sequence parameter in double circuit. The decomposing matrix of eigen-mode component is given. The zero sequence component relationship between voltages or currents at two terminals of double circuit was achieved by composing eigen-mode components.

提出一种采用特征模量分解方法对同杆多回线间的零序参数解耦，并给出了同杆双回线零序参数特征模量分解矩阵，通过特征模量分解得到同杆双回线路两端之间的零序电量关系。

Two 15nt complementary ssDNA primers were ligated into double stranded satRNA.Complete sequence of satRNA was obtained by RT-PCR using these 15nt ssDNA as amplification primers.Phylogenetic analysis showed that the identity of this 383nt satellite and some documented satRNAs was 72.6 to 99.5% at the nucleotide level.

以常规引物对感病植物的总RNA进行RT-PCR扩增，获得CMV RNA3全长克隆，经测序显示该RNA3序列属于CMV亚组Ⅱ；通过在卫星dsRNA两端分别加上15nt的单链DNA接头，以接头互补序列为引物进行扩增获得一个383nt的卫星RNA的全长序列。

For example, when the cursor passes over a window's frame, the cursor changes to a double-ended arrow showing the axis in which the window edge can be stretched.

比如，当光标通过一个窗口的边框时。光标就会变成两端都是箭头的形状。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
