查询词典 fluctuation

This paper is studying fluctuation of price, backwardation and contango in future markets. Based on the theory of future market and spot market, it takes a further analysis of Robert and Nir's study of backwardation in oil future markets. By data acquisition and processing, descriptive statistics and time series analysis, it investigates the relationship between backwardation and the equilibrium of oil future prices and spot prices.

这样设计的目的是为了得到遮蔽物释放后无法获得没有遮蔽物时测量处接收机所接收的每个激光脉冲的能量，从而消除脉冲能量起伏对测量精度的影响。

Based on the analysis of micro -bolometer resistance -temperature characteristics, a new readout circuit was proposed. It allowed micro -bolometer operate without a temperature stabilizer over a wide range of ambient temperature. And it need a Flash memory to store the correcting factors of different temperatures and a temperature sensor to detect the ambient temperature of the micro -bolometer. By utilizing the factors in the Flash memory, Digital Analog Converter controls the micro -bolometer bias current to compensate the fluctuation of ambient temperature.
