表面

Thermal spraying technology is an important part of surface engineering science.

热喷涂技术是表面工程学的重要组成部分，它是一种材料表面强化和表面改性的新技术。

Generally,it is considered that cotton fibre is a column and its surface is smooth.The surface structure of Xinjiang long fine hair cotton is researched by using electronic microscope scanning (S-570 Japan).The result shows that the cotton fibre is not a column,but is spiral.The fibre of only 15%does not twist.The surface of the fibre is not smooth,and there are burrs on it.These characteristics would be another important factor effecting the stickability of cotton.

一般认为，棉纤维呈圆柱状，纤维表面是光滑的，笔者以新疆长绒棉为研究对象，用日立S-57日扫描电镜，研究了棉纤维的表面结构，结果表明，棉纤维并非呈圆柱状，自然状态下呈螺旋形，象氨基酸那样，根据概率估计，没有扭曲的约占15%，棉纤维表面并不光滑，有毛刺，这种结构特性是影响棉花粘着性的又一重要因素。

Substrate of subaerial algae comprise rock surface、soil surface and tree trunk.

亚气生藻类的生长基质主要有岩石表面、土地表面及树干表面。

Do not just pay attention to your superficies everyday.

不要每天都只看到表面的自己而已，修道要深入，做人也要深入，做人不能只做表面，这样别人也会以表面来对你们。

Therefore,parameters of its electrochemical properties,especially the surface potential and the surface charge density,are of the most important.

但是关于土壤表面电荷性质的资料特别是关于表面电位、表面电荷密度的资料还相当缺乏，最主要原因是长期以来缺少可靠的测定方法[2]。

The dynamic equation describing the relationship between surface charge density and voltage is established. The constants of voltage／field strength A and B are introduced.

建立了电压与绝缘子表面电荷分布的动态方程，分析了直流电压作用下表面电荷的积聚过程，并给出了绝缘子表面电荷动态分布的近似表达式。

According to the changes of surface contact angles of samples.we analysis the function of plasma etching.

测试表面接触角的变化，分析等离子体对样品表面的油脂污染的清除作用及等离子体在表面发生的一些物理化学反应。

In constructing the surface enclosing each patch, NURBS (non-uniform rational B-spline) surface is employed to describe a three-dimensional free surface.

在构造表面时，应包括每一个片，NURBS表面被用来描述一个三维自由表面。

Ultrasonic cleaning is a good fit for a wide range of applications, from removing swarf and grinding and polishing residue to treating parts covered in oil, grease, or layers of paint.

超声清洗是工业领域一种广泛应用的新方法，可以去除工件表面的磨削，研磨，抛光后表面残留的碎屑，去除工件表面残留的油污，甚至可以去除油漆层。

By using opposite sides of the same pyroelectric lithium tantalate crystal, the Weizmann team produced two surfaces with opposite charges during cooling—one surface developed a positive charge as the temperature decreased, the other a negative charge.

通过使用同一种热电物质——鉭酸锂晶体的两个对面，魏茨曼团队在制冷过程中制造出了两个带有异种电荷的表面——随着温度下降，一个表面带上正电荷，另一个表面带上负电荷。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
