A commercial Ti: Sapphire laser (Coherent Inc. 899-29 mode) can provide seamless scans as wide as 10THz and with the help of a wavemeter and a computer in 0.7～0.9μm wavelength range.

本文的目的是在CR899环行腔钛宝石激光器的基础上，扩展其波长自动扫描范围至0.9μm以上，为近红外波段的高分辨光谱研究提供必要的实验手段。

If one is too well-read, then one does not know right is right and wrong is wrong.

一个人要是太博学，就无从分辨对之为对错之为错。

He got into a situation wherein it is hard to decide what is right and wrong.

It is that time when you know when to say yes, when to say no, and when to say WHOOPEE!

也就是你能分辨何时应该说好，何时应该说不，何时可以欢呼的时候。

The content ofone liver protein band (R_f=0.79) at 1℃was significantly higher than at room temperature (P＜0.05).On the 2-D native-PAGE/SDS-PAGE gel, the content of P spot (MW=51kDa, R_1=0.47on the 1D native PAGE gel) at 1℃was significantly higher than at room temperature (P＜0.05), and the content of N spot (MW=65 kDa, R_f=0,94 on the 1D native PAGE gel) at roomtemperature was significantly higher than at 1℃. These protein spots may be related with the adaptation to the low temperature of the Heilongjiang wood frog.

黑龙江林蛙肝脏蛋白电泳显示，胶浓度6％的肝脏PAGE图谱分辨率高、谱带多，可分辨出15～19条谱带，其中1℃组R_f=0.79蛋白含量比室温组显著增加(P＜0.05)。2-D native-PAGE／SDS-PAGE电泳时，胶浓度为12％时分离效果较好，蛋白斑点较多。1℃组中P蛋白斑点(MW=51kDa，一向PAGE的R_f=0.47)显著性上调(P＜0.05)，N蛋白斑点(MW=65kDa，一向PAGE的R_f=0.94)显著性下调(P＜0.05)，推测这两种蛋白可能与黑龙江林蛙在低温环境下的适应性变化有关。

The property of the lowest excited triplet states of xanthone in acetonitrile has been investigated by using time-resolved laser flash photolysis at 355nm. The transient absorption spectra and the quenching rate constants of the excited xanthone with several amines have been obtained.

用时间分辨的激光闪光光解的方法在乙腈溶剂中研究了呫吨酮的激发三重态的性质，并得到了呫吨酮激发三重态和胺类、醇类以及酚类反应的瞬态吸收光谱和猝灭速率常数。

I am not sure if the analogy is right, but I am sure it will help you to distinguish the Yin-Yang and Ci-Xiong

我不知道举这样的比喻对不对，但是，我肯定你们会把阴阳和雌雄分辨出来

Stay longer and you can get a real feel for what makes Napa Cabernet or Syrah or Zinfandel so distinctive.

时间长了，你就能分辨出纳帕山谷中的赤霞珠、西拉、仙粉黛的区别。

The acetated and hydrogenated urushiol dimer has been separated,and studied by hetero-J resolved 2D-NMR,homo- and heteronuclearchemical shift correlation 2D-NMR and long-range coupled chemicalshift correlation 2D-NMR.The results show that the urushiol dimerare most diphenyl and alkyl phenyl ether structures.Furthermore,IR and MS data also has conformed this structures.

本文将酶催化预聚后的生漆，催化加氢后，乙酰酯化，再进行离心旋转薄层层析，分离得到二聚体主要组分，用异核J分辨谱，同核化学位移相关，异核化学位移相关，远程偶合异核化学位移相关等2D—NMR技术，全面研究了其结构，得到了联苯型和烷基芳醚型聚合结构的结论。

As one American columnist acidly observed, at times it was "hard to tell who was Hu."

正如一位美国专栏作家尖刻的评价那样，有时候&真的很难分辨他们两人里面谁才是胡&。

But we don't care about Battlegrounds.
