但由于起步晚，加之发展不完善，我国的房地产市场呈现出较为明显的起伏性波动和其他一些较为典型的初级市场特征。

The peak time detecting circuit which is composed of full-wave rectification circuit and differential circuit can detect the reach time of echo signal accurately.

采用时间增益补偿技术，补偿超声波在空气中的衰减，减少回波信号的起伏；由有源全波整流电路和微分电路等组成峰值时间检测电路，可正确检测回波的峰值到达时间。

Use the hair small to furl gently, ten minutes small after ironing, can appear rise and fall not big curvature, if add a few to carry,catch, more show amorous feelings 10 thousand kinds.

把头发用小卷轻轻卷起，十几分钟的微烫之后，就会出现起伏不大的曲度，如果加几缕挑染，就更显风情万种。

两极性或作用与反作用在自然界中随处可见：黑暗与光明、炎热与寒冷、潮落与潮涨、雄性与性、动植物的吸气与呼气、动物体内的体液数量与质量的均衡、心脏的收缩与舒张、液体的波动和声音的起伏、离心力与向心力；此外在电荷、电流和化学的亲和性上也不难发现这点。

It was a season of ups and downs and, while it was nice to win the Inter Continental Cup, it wasn't so good in the World Club Competition in Rio, when we were beaten by Vasco Da Gama and eliminated at the first stage.

这个赛季球队常有起伏，赢了洲际杯固然值得庆祝，但在世俱杯第一阶段在里约热内卢就被瓦斯科·达伽马队淘汰也太糟了。

In order to model the best geoid, two main topics are studied.

The symmetry of the planetary relief is broken in the western Pacific where the geoid surface is uplifted.

在西太平洋中，星球地势起伏的对称受到破坏，那里的地球体表面受到抬升。

The signal-phase-matching principle of three and multi sensors are proposed in this dissertation. By using these principles, the formulae of estimated spatial signal are derived. The physical meaning and the geometric interpretation of these principles are given. The performances of estimated signal are analyzed when the phase of expected signal and the amplitude of noise are fluctuant.

提出了三元阵及多元阵的信号相位匹配原理，推导了利用信号相位匹配原理的空间信号估计公式，给出了信号相位匹配原理的物理意义及几何解释，分析了信号相位和噪声幅度起伏对信号估计性能的影响。

The Els Club measures a formidable 7,538 yards and is a combination of a links golf course and traditional classical-era design set on undulating slopes of native desert vegetation.

它的总长度是让人望而生畏的7538码，结合了林克斯球场以及根据当地波浪状起伏沙漠地形运用的传统经典设计风格。

The split between the two groups can hardly be papered over.
