起伏

By thermodynamically and dynamically calculating and analysing ,a new growth mechanism of spherical graphite has been proposed ,that is,the spherical graphite does not grow inwardly,but grow outwardly and when spherical graphite grow outwardly carbon atoms come into and fill-up the entocoele of spherical graphite by the diffusing way.

通过对石墨球最终表面的形态进行分析，可以获得气泡的表面并不是石墨球的最终表面，石墨球表面主要由于受到石墨球表面各微晶长大速度不均匀性、铁水中的三大起伏、微量元素与碳原子的竟相吸附、由于浓度梯度和温度梯度所引起铁水的对流等各种因素的综合影响结果使其表面成为凹凸起伏的形状

The results show that thermoluminescent anomalies, whose two edges are higher and the middle is lower, indicate the uranium deposit, the rapidity step of natural voltage indicates the transitive section of oxidation-reduction.

通过室内和野外实测，结果表明土壤天然热释光异常曲线矿体边缘高值，矿体上方低值异常的曲线特征反映了铀矿化存在的可能；中间低值段越宽，起伏变化越小，矿化相对较好；低值段宽，但起伏变化相对较大，则矿体连续性变差；中间低值段狭窄，反映了矿化较差或没有矿化。

We present a traveltime computation method suitable for rugged topography and irregular interfaces.

以FMM为基础，提出了一种在复杂地质条件下计算起伏地表起伏界面地震波走时计算方法。

The key of the simulation is to select a suited set of models and parameters which represent the motion and the echo of moving targets, Because the perform of microwave radars operating over the moving targets is very complicated.In this paper, we discuss how to simulate the motion of targets with a method of parameters simulation. And then we get a track clearly through controlling the flight parameters and the time increasing. The way reduces the error.This paper also particularizes the prime parameter of the echo--Radar Cross Section which is influenced by many factors.

对于目标的实时运动特性，本文采用了航迹的参数模拟法，通过控制目标的飞行性能参数与时间增量的大小来模拟目标的真实运动，避免了多种因素所引起的飞行误差，效果良好；此外，本文详细分析了表征运动目标回波特性的雷达截面积与雷达波长、目标姿态、极化方式及视角的关系，在此基础上，考虑了RCS的两种起伏特性以及天线对其的调制作用，得出了快、慢起伏目标回波的仿真数据，并对二者进行了比较。

From these parameters, the new findings are:(1) The ice density from investigation is lower than 2-3 tenths compared with that from NOAA Ice Chart, and the ice thickness in the summer is less than 2 m compared with the results investigated during the First Chinese National Arctic Research Expedition in 1999 (CHINARE-1999);(2) The standing deviation of ice bottom fluctuation is 3.8 times of that of the snow surface on the ice sheet and (3) the maximum speed of ice floe CHIS7 is 1300 m/h in rotation and oscillation.

这些参数指出：现场调查的海冰密集度同NOAA冰图上的密集度相比低2~3成，而厚度比1999年的中国首次北极考察结果减少2m；冰层底面起伏方差约是冰层表面积雪起伏方差的3.8倍；浮冰最快以1300m/h速度运动并伴随振荡旋转。

They then threaded the wool wefts, leaving some tight and others sinuous, giving an immediately recognisable wavy finish to the surface of the carpet.

因为经线不是设在同一平面位置的，所以织出来不是板板的一块，而是有立体起伏感的，有的毛被压实，有的毛蓬起来，就有起伏了

Das and introduced the energy pulsations of output signal train as well as the conjugate signal pulse.

Das对于模式效应的定义，引入了输出信号码流的能量起伏以及共轭波码流的能量起伏两个参量。
