帮忙改几句英文句子，每句都有中文大意。只要改一句就有金币。 A tentative theory interpretation of the anomalously experimental results is given, which introduces a qualitative nonlinear model of coherent weakly damped electron-lattice vibrations in structural order of all-trans-β-carotene. 句子大意：对这种奇异现象，我们用D.YU.Parachuk提出的非线性相干弱阻尼电子-核振动模型和Placek的共振拉曼理论模型给予分析和解释。 However, very little information is currently available concerning the RSCS of β-carotene at low concentrations. 句子大意：然而，关于低浓度下β-胡萝卜素散射截面的研究却少之又少。 According to equation(3), the absolute RSCSs of C=C and C-C stretching modes of β-carotene in CS2 at different concentrations were calculated based on the Fig.1. 我想表达是根据图1的信息来计算，（based on the Fig.1.） 希望高手能帮助改改。 As shown in Figs.2and 3, the tendency of the RSCSs to increase with decreasing solution concentration is in agreement on the equation 我们根据（图2，图3）实验数据，拟合了不同浓度下CC键拉曼散射与浓度的关系的关系式。 It is obvious an universal power relationship between CC bond RSCSs and concentrations at low concentrations from 10-6 M to 10-11M. 显而易见在10-6-10-11M浓度范围内，对C=C键和C-C键的拉曼散射截面与浓度成指数关系。 Firstly, with decreasing concentration, the UV-visible spectrum of β-carotene in CS2 progressively becomes narrows. Secondly, the depolarization ratio of the CC stretching modes of β-carotene in CS2 becomes large in the Raman spectra. 第一，随着浓度降低，β-carotene溶液的紫外-可见光谱逐渐变窄。第二，在拉曼光谱中β-carotene的CC键的退偏比变大。 |

A theoretical interpretation of the anomalously experimental results is given, whichis based on the introduction of a qualitative nonlinear model for coherent weakly damped electron-lattice vibrations in structural order of all-trans-β-carotene. However, little information is available concerning the RSCS of β-carotene at low concentrations. According to equation(3), the absolute RSCSs of C=C and C-C stretching modes of β-carotene in CS2 at different concentrations can be calculated as shown in Fig. 1. As shown in Figs. 2 and 3, the trend that RSCSs is toincrease with decreasing solution concentration is in agreement with the equation. It is evident that there is a universal power relationship between CC bond RSCSs and concentrations at low concentrations from 10-6 to 10-11M. First, with decreasing concentration, the UV-visible spectrum of β-carotene in CS2 progressively becomes narrows. Second, the depolarization ratio of the CC stretching modes of β-carotene in CS2 becomes large in the Raman spectra. |
