The purpose of this thesis is to explore other yet undiscovered contrast origins and unused contrast agents of third-harmonic-generation inside biological tissues, and apply to the preliminary studies of medicine based on a nonlinear laser scanning microscopy system using a femtosecond Cr:forsterite laser centered at 1230-nm.

这篇论文的目的是利用了以中心波长为1230nm的铬贵橄榄石雷射做为光源的非线性雷射扫瞄显微镜系统去探索生物体中其他仍未被发现的三倍频对比来源以及尚未被使用的三倍频外加显影剂，并初步的应用於医学研究上。

By adopting an intracaity flat surface with low reflectivity and controlling the ratio of subcavity lengths, the repetition rate of this compact femtosecond Cr:forsterite laser can be multiplied from 100 MHz to 500 MHz in femtosecond regime. Repetition rate higher than 1GHz can also be achieved.

接著我们置入一个低反射率的腔内平面，将共振腔分为两个次腔，透过次腔长度比例的控制，我们可以将飞秒脉冲的重覆率从100百万赫兹倍增到500百万赫兹，甚至到更高的十亿赫兹以上。

We have combined 2PF microscopy with higher-harmonic optical microscopy based on the femtosceond Cr:forsterite laser with the aid of new transgenic lines tagged with HC-red fluorescent protein to obtain molecular, morphological, and structural protein information in biological tissues.

有著基因转殖技术的辅助及利用在於生物穿透较深波段的近红外光飞秒雷射光源，我们结合了双光子萤光显微术和倍频光学显微术来取得生物组织中的分子影像、型态学及有结构的蛋白质资讯。

目的：分析臀肌挛缩症的cr骨盆平片影像表现。

A new method for the simultaneous determination of Pb, Cr, and As in edible glutin was established.

建立了同时测定食用明胶中铅、铬和砷的新方法。

The recovery was 94.0%~106.0%. The method was simple, rapid, accurate and suitable for determination of Pb, Cr and As in edible glutin.

该法操作简便、快速，结果准确，适用于食用明胶中铅、铬和砷的快速测定。

Corrosion kinetics were measured gravimetrically,and corrosion product scales were physically examined and chemically analyzed.

测定涂盐的 Fe-Cr合金于 O_2-0.1、0.5和1.0%(SO_2+SO_3)气氛中在560～750℃温度区间腐蚀动力学曲线，并对腐蚀产物进行物理观察和化学分析。

We also report the exsolution texture of Cr-spinel in orthopyroxene in the studied harzburgite, and suggest that it is the result of a metamorphic reaction induced by the drastic increase of oxygen fugacity during the rapid emplacement of Darbut ophiolite.

方辉橄榄岩中的斜方辉石发育铬尖晶石出溶结构，出溶棒的成分特点表明，该结构是达拉布特蛇绿岩在快速就位过程中环境氧逸度突然升高诱发变质反应的结果。

The results of thermodynamical study and experimental study show that hexavalent chromium ion in t...

热力学研究和试验研究结果表明，Cr＋6在烧结－炼铁工艺中可以很好地被消除。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
