Secondly, femtosecond time-resolved studies using fluorescence depletion spectroscopy were performed on Rhodamine 700 and Oxazine 750 in solutions to study the ultrafast dynamics, such as vibrational relaxation and the energy transfer from the solute to solvent. The orientational relaxation process of these dye molecules have been study in solution by the polariton resolved FS TR SEP FD.

我们利用此技术，对LD700和OX750两种染料分子电子激发态的振动弛豫和溶质与溶剂分子间碰撞传能等超快动力学过程进行了详细地实时研究，获得了它们的激发态分子在不同溶剂和体系温度等实验条件下的飞秒时间分辨荧光亏蚀谱：并首次采用极性分辨的飞秒荧光亏蚀光谱技术研究了溶质的取向弛豫过程。

Dimensions: This image is roughly 61 arcseconds (1.5 light-years or 0.47 parsec) wide.

图像尺寸：61角秒，或者说是1.5光年、0.47秒差距。

A harsh rocky world less than a parsec away from Tatooine, Geonosis is a ringed planet beyond the borders of the Galactic Republic.

在距离塔图因不到一个秒差距（译者注：1秒差距=3.26光年）的地方有一个叫吉奥诺西斯的星球，这是一个位于银河共和国国界外一个带着光环的行星。

At last 30 seconds, I had a terrible heart beat. Our tactics were ingenious but on huge risks. In order to control the ball in last 20 seconds, we fouled on purpose, and the rival would need to have penalty shot...

在混乱中BYCO进了很关键的一球，然后最后30秒真的让人心跳加速，咱的作战非常巧妙，为了能在最后20秒控球，我们故意犯规，然后让对方罚球。

In the experiment the time-average coolant mass flux is varied from 300 to 400 kg/m2s and the amplitude of the coolant mass flux oscillation is fixed at 0%, 5% and 10% of . The period of the coolant mass flux oscillation varies from 10s to 30s.

在实验参数范围上，介电液FC-72平均质量通率从300到400 kg/m2s而且流量的振荡振幅为0%、5%、10%，流量的振荡周期为10秒到30秒。

The unit of measure for H in the SI or mks system is ampere turns/meter and in the cgs system, the oersted (1 amp turn/m = 4π 10-3 oersted = 4π 10-3 gilbert/cm). 0 is called the permeability of free space; 0 = 4π 10-3 weber/amp-m in SI units and 1 gauss/oersted in cgs units.

H 在国际单位制或在米-千克-秒单位制中的度量单位是安培匝/米，在厘米克-秒单位制中为奥斯特(1 安培匝/米= 4π 10-3 奥斯特= 4π 10-3 吉伯/厘米) 0 为自由空间导磁率；0 = 4π 10-3 韦伯/安培米=1 高斯。

Picosecond and femtosecond laser induced darking in some optical glass were studied.

研究了某些光学玻璃在皮秒和飞秒激光照射下产生的暗化特性。

Compared with picosecond pulse laser, the intense of pulse is the main factor of the finally temperature of electron.

发现电子与晶格耦合系数影响材料表面电子的温升及电子与晶格温度耦合时间；与皮秒激光比较，脉冲功率密度是影响电子最终温度的主要因素；飞秒激光烧蚀金属材料的厚度可达到表层厚度量级。

Besides,we will continue strive for the higher fields of ultraviolet,femtosecond , picosecond laser and so on .

另外，我们还将向紫外激光、飞秒及皮秒激光等高端领域不断进取，永保国内领先，争创世界一流。

The faster decays on the hundreds of the femtosecond time scale and the slower decays on the order of picosecond are found.

实验发现两个超快动力学过程：飞秒量级的快速弛豫过程和皮秒量级的慢速弛豫过程。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
