演化曲线
Examples
- This paper also discusses the strontium isotope evolution curve published over the world , present strontium isotope results of the section of cambrian in xiushan of chongqing
本文评述了国际上已有的寒武系海相碳酸盐的锶同位素演化曲线，公布了重庆秀山寒武系海相碳酸盐的锶同位素分析结果。 - In the examples we get some evolution curves , such as the growth rates and shape functions , which are used to analyze the stability problems for the boundary layers of the fuselage and the wing
算例给出了扰动幅值增长和形状函数等演化曲线,并对机翼、机身的边界层稳定性进行了分析和研究。 - Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence , observation of thin sections , and analysis of sr and mn . the mn / sr value of all samples presented in this paper are less than 2 , and the cathodoluminescence is dull , however , the samples from the cambrian underwent diagenetic alteration to a certain degree , and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete . the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world , supporting the notion of global consistency of strontium isotope composition of marine carbonates
根据锯同位素地层学的基本原理，利用已有的锯同位素演化曲线，笔者确定重庆秀山寒武系剖面寒武系底界、下一中寒武统界线和中一上寒武统界线都应适当下移；另外尝试确定了重庆秀山寒武纪剖面一些关键点的年龄，累积厚度1380m处的年龄为503 ? 509ma ，累积厚度1900m处的年龄约为500ma ，这对秀山寒武系剖面下、中寒武统和中、上寒武统界线的确定具有参考价值。 - At last , take a three - storeyed and two - span reinforced concrete frame as example , its damage value under cyclic load at different time is computed by the program . and the damage evolution curve of different element and whole structure is also obtained . as result the damage evolution law of reinforced concrete structure under cyclic load is found , which provides basis for the study of collapsing mechanism of reinforced structure under seismic force
最后，以一个三层两跨的钢筋混凝土框架为例，应用作者自编的程序计算了循环荷载作用下该框架结构在不同时刻的损伤值，并给出了其不同构件及整体结构的损伤演化曲线，揭示了循环荷载作用下钢筋混凝土框架结构的损伤演化规律，为地震力作用下钢筋混凝土结构的倒塌机制问题的研究提供了依据。 - It has been shown that : the little indentation which represents the quantum noise of the system appears in the evolution curves ; the quantum noise which is caused by virtual photon field gradually becomes weak when w increases , the quantum noise increases when n increases ; the virtual photon process make the antibunching effect strengthen , make the squeezing degree deepen obviously , and lead to the additional vibration of entropy , the oscillation extent of the additional vibration of entropy increases when n increases and decreases when co or g increase . besides , the quantum dynamics of two coupling atoms interacting with a single mode ligh t field in a kerr medium is studied in this paper ; the influences of the kerr effect on the mean photon number , the degree of second order coherence of field , the evolution of the field entropy and the squeezing effect are also discussed
)的增大，量子噪声分别减小和增大；虚光子过程使光场的反聚束效应增强，使光场的压缩程度明显加深，并引起了附加的“熵振荡” ，这种附加“熵振荡”的幅度将随着光场初始平均光子数( ? )的增加而增大，随着光场频率和原子间耦合系数g的增大而减小。本文还研究了充满kerr介质腔中“耦合双原子-单模光场”相互作用系统的量子动力学性质，研究了克尔效应对场的平均光子数、二阶相干度、场熵演化特性及光场压缩效应的影响。
