查询词典 fluctuate

Base on the structure, character of the supply chain and the theory of the supply chain management, we analyze the relation between the uncertainty of the supply chain and the stock, and build a mathematical model on bullwhip effect by using the difference to describe the fluctuate of the demand.

The results show that:(1)the low-noise source-follower circuit can be effectively used to measure the output of PVDF thin film;(2)the piezoelectric coefficient D33 of the PVDF is very sensitive on temperatures;(3)the value of D33 intensively fluctuate in initial loading stage,this means that a pre-load is needed in practice application to keep a constant piezoelectric coefficient D33 of the PVDF;(4)when the compressive load is imposed on the surface of the PVDF along a incline direction,D33 value is obvious changed with changing incline angle,and(5)the frequency bandwidth of the PVDF thin film is very wide,it is more suitable to measure strike or impact loading at various loading conditions.

结果表明：(1)低噪声源跟随电路可有效测量PVDF 薄膜输出；(2)PVDF压电薄膜的压电系数D33对温度很敏感；(3)D33值在加载初始阶段波动很大，所以实际应用中应给PVDF提供一个预压载荷，以确保有一恒定的压电系数D33；(4)当压载荷沿倾斜方向作用在PVDF 表面时，由于有剪切力作用，D33 值会随着倾斜角的变化发生显著改变；(5)PVDF 薄膜具有很宽的频响，更适用于测定不同载荷条件下的侵彻或冲击等动态载荷。

本研究在探讨保险新契约之保费的景气循环状况与景气分数的制定，其中我们利用六种不同的保险新契约保费当研究对象，包括个人人寿保险保费、团体人寿保险保费、个人健康保险保费、团体健康保险保费、个人伤害保险保费和团体伤害保险保费，除了观察原始资料的波动外，亦采用最大概似估计法来估计马可夫转换模型的未知参数，尝试著去认定景气循环的高峰与谷底。

The analysis reveals that intensity appears to fluctuate with a clear, welldefined rhythm.Although the strength of the magnetic field varies irregularly during the short term, there seems to be an inevitable longterm decline preceding each polarity reversal.

因此在四个选项中： A.decline的意思是&拒绝；变小、变弱&，B.intensify的意思是&变得更强烈、加剧&，C.fluctuate的意思是&涨落、波动&；D.reverse的意思是&使反转、倒退、颠倒&，例如：Writing is reversed in a mirror。

Groundbreaking research by two french geophysicists promises to shed some light on the mystery.using 80 metres of deep sea sediment core, they have obtained measurements lots of magneticfield intensity that span 11 polarity reversals and four million years.the analysis reveals that intensity appears to fluctuate with a clear, welldefined rhythm.although the strength of the magnetic field varies irregularly during the short term, there seems to be an inevitable longterm decline preceding each polarity reversal.when the poles flip―a process that takes several hundred thousand years―the magnetic field rapidly regains its strength and the cycle is repeated.

答案为d。这一题目是根据上下文判断词意的题。flip的意思是&快速翻转&，它所在的句子的意思是&当两极互换――这一过程需要上万年的时间――磁场会很快重新恢复它的强度，新的一轮循环又开始了。&因此在四个选项中： a.decline的意思是&拒绝；变小、变弱&，b.intensify的意思是&变得更强烈、加剧&，c.fluctuate的意思是&涨落、波动&；d.reverse的意思是&使反转、倒退、颠倒&，例如：writing is reversed in a mirror。写出来的字在镜子里是颠倒的。d的意思与flip最接近。
