When the signal sources have different cycle frequencies, a method to estimate the optimal time lag is presented. It solves the severe problem that the conventional Cyclic MUSIC requires knowing the optimal time lag in computing the cyclic correlation matrix. A method of two-step search for DOA estimation by employing an interleaving technique and a Joint Estimation Strategy is developed to overcome the inadequency of signal sources with the same cycle frequency having no optimal time lag.
当信源的循环频率各不相同时,提出了一种估计最佳延时的方法,解决了传统Cyclic MUSIC算法计算循环相关矩阵需要已知最佳延时的问题;为克服多个具有相同循环频率信源不存在最佳延时的不足,利用交错技术和联合估计策略,提出了两步搜索估计DOA的方法。

Based on chapter two, In chapter three, the method of multiple scales is introduced to the study of the multiple-dimensional nonlinear stochastic systems under random external excitation. Using method of multiple scales, we strictly deduce the equation of modulation of amplitude and phase. The effects of random excitations are analyzed; numerical simulations verify the results. Theoretical and numerical simulations show that when the intensity of the random excitation increases, the nontrivial steady state solution may be changed from a limit cycle to a diffused limit cycle.
在第二章基础上,第三章将多尺度法引入到相应的随机系统的研究中;严格推导了系统的约简方程,用矩方法求出稳态解应满足的方程,获得一些结果;并且数值模拟结果与理论推导的结果是一致的;并注意到,与其对应的确定性系统相比较,系统响应从周期解变为近似周期解,系统的相轨线从极限环变为扩大的近似极限环;随着激励带宽的增大,此扩大的近似极限环的宽度将增大。

Look of your menstrual cycle is longer, if it is within 28 days of the menstrual cycle, in the next period on the 14 days before the countdown, then that is on the 21st day of ovulation is your day, can be arranged makelove in 19,21 , 23, three on the line, if you are 29 days of the cycle, that is, on the 18th day of ovulation, to such a method, not necessarily very accurate, because sometimes ovulation will be affected by many factors, such as: mood, work stress and environmental change, food and drugs, there will be advanced or delayed, so the general recommendation in the ovulation period ovulation test strip under the combination could be more accurate to seize the day of ovulation.
要看下你的月经周期是多长了,如果是28天的月经周期,在下次月经日倒数的14天前,那么也就是21号这天是你的排卵日,可安排makelove在19、21、23号,三次就行,如果你是29天的周期,就是18号的排卵日,以此种方法计算,并不一定很准确,因为排卵有时会受很多因素的影响,比如:心情、工作压力、环境改变、食用药物等,会出现提前或推后,所以一般建议在排卵期里结合下排卵试纸会能更准确的抓住排卵日。

The First Law of thermodynamics and exergy analysis method were used to construct factors such as coefficient of performance , exergy efficiency and exergy index according to the AHT combined Carnot cycle model established. Aimed at the insufficient of the classical thermodynamics analysis method, the optimization relationships between the specific heating load and operating parameters, and between SHL and COP, was reasoned out using the Finite Time Thermodynamics method according to the characteristic of investment and capacity of AHT, and endo-reversible combined Carnot cycle model. Hence, the rationality of the energy utilization and the economic index, which related to the total heat transfer area, were both taken into account.
