监测值是瞬时浓度值，测次愈少代表性愈差。
Thus, the monitoring values obtatined can only represent the instantaneous concentration of pollutant.
本文结合模型试验，得出了不同温升及变率下表面横向浮射流的瞬时浓度场和流速场，进而分析得出随着温度及变率的变化浓度场的扩散范围、形态特点和趋势。
Based on the model test, the instantaneous concentration and velocity images in different temperatures and scales are put forwarded. And the range, shape and trend of diffusion are acquired.
焊剂中较高的松香浓度明显有益于焊点的抗剪切蠕变强度，而对瞬时剪切强度影响不大。
It was also found that higher concentration of rosin in flux is beneficial for shear creep resistance of the joints, while its effect on the instantaneous shear strength is less obvious.
研究结果表明：暴雨期内，非点源污染物浓度及瞬时流失量与径流峰值几乎同步出现，它们之间存在着非常密切的关系。
The results show that during storm period, non - point pollution concentration and momentary toss are co - occurence with the peak value of runoff, their relations are very closely.
所研制的排油监控系统能够通过传感器来测取油份浓度，流量和船速信号，并经计算机计算出油量瞬时排放率和排油总量。
This ship oil discharge monitoring and control system can measure signals of oil density, flow and ship speed by sensors and calculate instantaneous oil discharge rate and total oil discharged.
