显微镜使用

Methods: The hair samples were collected from 41 youth of Chinese Han in Shanghai. The amino acid makeup was analyzed by amino acid analyzer. The outer surface and cross section of hair were observed. The radial swelling of hair was determined by polarizing microscope. The tensile study of hair fiber was performed by mechanical testing machine.

收集41例上海地区汉族青年的头发样品，使用氨基酸与多肽分析仪进行氨基酸定量分析，使用电镜观察并测量头发表面及横断面形态，应用偏光显微镜测量头发的吸水径向膨胀特性，应用纤维强力试验机检测头发的拉伸性能。

The illumination used, so called soft x rays in the wavelength range of twenty to forty angstroms (an angstrom is one ten billionth of a meter), is also sufficiently penetrating to image intact biological cells in ma ny cases.

在许多情况下也能够穿透完整无缺的生物细胞并成像。由于使用的 X 射线的波长使软性 X 射线显微镜永远比不上电子显微镜可能具有的最高分辨力。

The principle of an optical microscope is quite simple; however, the resolving power of an optical microscope is limited by the wavelength of the light employed, being greater when the light source is shorter wavelength.

光学显微镜的原理很简单，然而光学显微镜的分辨率受所使用的光的波长的限制，光源的波长短，分辨率就高。

The surface morphologies of coal pitch spheres were characterized by scanning electron microscope and polarized light microscope. The effects of naphthalene content on the softening point of the modulated pitch, balling temperature on the spheres morphologies and the max mass ratio of pitch to the liquor were investigated.

使用扫描电子显微镜和偏光显微镜对沥青球的表面形貌进行表征，探讨了减黏剂萘含量对调制沥青软化点的影响，成球温度对球形貌的影响以及沥青／水相的最大质量比。

An optical microscope of good quality can produce magnifications of several thousands of times, but in practice it is employed only for magnifications up to approximately 1000 times.

一个高性能的光学显微镜能产生几千倍的倍率。但在实践中仅使用倍率约为1000倍的显微镜。

An optical microscope of good quality can produce magnifications of several thousands of times, but in practice it is employed only for magnifications up to approximately 1000 times.

一个高质量的光学显微镜的放大率是几千倍，事实上，通常使用的放大率只有1000倍，而电子显微镜则用来观察需要更高放大率的物体。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
