The resulting Taylor series can be evaluated far outside their radii of convergenceby means of appropriate methods of analytic continuation in the domain of complex perturbation parameters.


A continuation homotopy method for the inverse problem of operator identification and its application


This technique is a direct application of the continuation homotopy method for solving nonlinear systems of equations.


As a continuation of part I of the paper under the same title, we develop general monotonic enclosure methods for the couple systems of the splitting equations


The approach is based on the abstract continuation theorem from Mawhin and the apriori estimate of periodic solutions.

 Based on the data obtained from flume experiments, the conditions of formation and continuation of motion of density current with hyperconcentration are approached and the following conclusions are obtained.l.From the relationship between the effective Reynolds number and the resistance coefficient both calculated by the hydraulic factors at the section where density current plunged into the bottom of the reservoir, it is found that there are three types of flow patterns existed at the section, they are... Based on the data obtained from flume experiments, the conditions of formation and continuation of motion of density current with hyperconcentration are approached and the following conclusions are obtained.l.From the relationship between the effective Reynolds number and the resistance coefficient both calculated by the hydraulic factors at the section where density current plunged into the bottom of the reservoir, it is found that there are three types of flow patterns existed at the section, they are laminar flow, transition flow and turbulent flow. The criteria of the depth at the plunging section of density current described by Fan Jiahua asFr = 0.78 and K. Ashida as are only goodfor the case of turbulent flow and not for the other two cases.2. For density current of transition type, the depth of density current at the plunging section derived from the law of momentum is consistent with that of K. Ashida's formula except the coefficient is not a constant of 0.365 but is correlative with the yield stress as Eqs.(11) & (12).For density current of laminar type, there is no exchange of momentum at the plunging section. The depth of this section may be obtained by the principle of equilibrium as Eq. (14).The above mentioned equations conform well with the measured data.3.The condition of continuation of motion of density current varies with the type of flow. For type A, density current with ordinary concentration, the time of motion relies on the duration of the flood peak. For type B, density current of nonhomogeneous flow with hyperconcentration, the time of motion depends on the flood volume, sediment diameter and sediment content. For type C, density current of homogeneous flow with hyperconcentration, even though the discharge is small after the flood, density current can still move in the form of oscillating flow and intermittent flow as long as.Oscillating flow and intermittent flow, which are specific phenomena of instability of density current, are described in this paper. And, a new explanation is given regarding the difference between oscillating flow, intermittent flow and the general open channel flow.  本文通过水槽试验,研究了高含沙异重流形成的定量关系,以及保持持续运动的条件.发现高含沙异重流潜入点流态存在着紊流、过渡、层流三种,各类规律不同.文中还描述了不同于高含沙明流的异重流的不稳定性——阵流和间歇流特性.  The papre is the continuation of "PlanetaryScale Oscillation of the Equatorial Anomaly"[1]. It provides new evidences to prove that the planetaryscale oscillation (PSO) of the atmosphere in mesosphere can modulate the tide wind and when the tide wind moves to the E region, by means of the dynamo effect it can results in PSO of the electric field and Sq current. The electric field can transfer to F2 region along the geomagnetic field line and by means of the fountain effect it can results in the PSO of...

The electric field can transfer to F2 region along the geomagnetic field line and by means of the fountain effect it can results in the PSO of the equatorial anomaly. Because all of these oscillations come from the same source, the are synchronous.  本文是“赤道异常的行星波振荡”的续篇。提供新的事实以说明:由于中层大气的行星波振荡会调制到潮汐风上面,潮汐风上升到E层发电机区域,通过发电机效应产生电场及S_q电流体系的行星波振荡。电场沿磁力线传到F_2层,通过“喷泉效应”引起电离层赤道异常的行星波振荡。所有这些振荡来源相同,所以是同步的。  Using data of nine ionospheric stations of China during Dec., 1975Dec., 1986, it is presented that under the conditions of certain latitudes and solar activity, night time f0F2 shows a seasonal anomaly similar to that of the daytime foFz. This anomaly obviously shows two features: it only occurs in low latitudes; the higher solar activity is, the larger exlent of the degree of the anomaly is to. The night time seasonal abnormal phenomenon is the continuation of daytime seasonal abnormal phenomenon. The... Using data of nine ionospheric stations of China during Dec., 1975Dec., 1986, it is presented that under the conditions of certain latitudes and solar activity, night time f0F2 shows a seasonal anomaly similar to that of the daytime foFz. This anomaly obviously shows two features: it only occurs in low latitudes; the higher solar activity is, the larger exlent of the degree of the anomaly is to. The night time seasonal abnormal phenomenon is the continuation of daytime seasonal abnormal phenomenon. The promary mechanism of the phenomenon is the seasonal variation of neutral air (O, O2, N2) concentration ratio O/O2 and O/Nz, caused by the summer hemispher to winter hemisphere air flow. It is analysed why the night time seasonal abnormal phenomenon is limited in low latitudes and why the abnormal degree changes with solar activity.  本文用1975.12—1986.12我国9个电离层站的资料分析得出,在一定的纬度和太阳活动条件下,夜间f_0F_2存在季节异常现象.夜间季节异常现象具有两个明显的特点:只有低纬才具有夜间季节异常特征;太阳活动高年夜间季节异常的程度增加.夜间季节异常是白天f_0F_2季节异常现象的延续,夏半球至冬半球的大气流动造成的中性气体浓度比(O/O_2和O/N_2)的季节变化,是形成f_0F_2季节异常的根本原因.并初步分析了夜间季节异常的低纬局限性及随太阳活动变化的成因.   << 更多相关文摘
