time scale ratio

In the field of conservation physiology, we chose urinary purine derivatives and their ratio to creatinine for the fine time-scale analysis, which could estimate deer nutritional condition preciously.

在保护生理学范畴内，选用了尿液嘌呤衍生物以及尿液嘌呤衍生物与肌酐的比值作为适用于小时间尺度，且能够精确评估鹿类营养状态的指标。

It is a large-scale mixed-signal circuit with time-delay integration ( TDI) function to enhance the signal to noise ratio ( S/ N), and defective element deselection ( DED) function to decrease the probability of bad columns.

该读出电路是一个大规模混合信号电路，集成了时间延迟积分以提高信噪比，实现了缺陷像素剔除以提高阵列的可靠性。

The doublets observed on Changshu Station following the South Yellow Sea middle-intense earthquakes show such variations in spectral ratio slope, but the time scale of one event of the doublets extends to 9 months before the main shock.

常熟台双子地震P波谱比对数斜率时间进程在南黄海地震发生之前也存在这一现象，但出现异常的时间扩大到9个月之内。

The reaction temperature, reaction time and reactant ratio can be accurately controlled when performing organic reaction in microreactor. Moreover, re-optimization in production process at each stage of scale-up can be avoided.

在微反应器中进行有机化学反应不仅能够实现对反应温度、反应时间以及反应物配比的精确控制，还能避免有机反应在放大生产过程中的再优化过程。
