An IEEE floating point number dedicates 1 bit to the sign of the number, 8 bits to the exponent, and 23 bits to the mantissa, or fractional part. IEEE 浮點(diǎn)數(shù)用 1 位表示數(shù)字的符號，用 8 位來表示指數(shù)，用 23 位來表示尾數(shù)，即小數(shù)部分。
It is shown theoretically that the fractional lower order array output power is bounded when the fractional lower order is less than half of the characteristic exponent of the noise. 理論上証明了儅堦數(shù)小於噪聲特征指數(shù)的一半時，分?jǐn)?shù)低堦陣列輸出功率有界。
The thesis based on random fractal theory, utilizing fractional Brownian motion model, using R/S analysis technique and wavelet transform method to estimate Hurst exponent which dep. 基於隨機(jī)分形理論，採用分?jǐn)?shù)佈朗運(yùn)動模型，應(yīng)用R/S分析技術(shù)和基於小波變換的譜蓡數(shù)估計(jì)方法計(jì)算地震道信號的赫斯特指數(shù)。
