The one-parameter infinitesimal transformation group and infinitesimal transformation vector of generator are described in detail. The conformal factor in the determining equations under second-class Mei symmetry is found. The relationship between Appell system＇s conformal invariance and Mei symmetry are discussed. And Appell system＇s conformal invariance under second-class Mei symmetry may lead to corresponding Hojman conserved quantities when the conformal invariance satisfies some conditions.

The vertical social mobility between social classes tended to slow down and the social structures and stratification became solidified. Phrases such as "second generation of the rich,""second generation of officials,"and "second generation of the farmers"appeared frequently on the Internet and other media,which to some extent reflect the trend in social structure. However,little research has been conducted to address these issues in recent years.This field is in great need of systematic and authoritative surveys and studies on social fragmentation,marginalization,stratification,and mobility.展开更多

The definition about conformal invariance of Birkhoff systems under second-class Mei symmetry is given. The conformal factor in the determining equations is found. The relationship between Birkhoff system＇s conformal invariance and second-class Mei symmetry are discussed. The necessary and sufficient conditions of conformal invaxiance, which are simultaneously of second-class symmetry, are given.

Not only in the western developed countries, but also in developingcountries, for example, China is also influenced by the approach of CLT in its English as a Second Language(ESL) classes. Particu-larly ESL classes of universities in China have used CLT as an important approach in teaching English speaking, listening, readingand writing. From the previous study and research there are evidences showed that CLT for ESL in universities in China have theiradvantages and values,but the classes still have some problems and need to develop which proved the hypothesis before research.展开更多

Through the linear transforma tion between the first generalized covariant derivative and the second one, the second covariant differential transformation group is set up.

In the successive approximation theorem, we prove that, for each integer n ≥ 1, finitely many candidates for the Galois group of the nth stage of the p-class tower over F are determined by abelian type invariants of p-class groups C1pE of unramified extensions E/F with degree [E : F] = pn-1. Illustrated by the most extensive numerical results available currently, the transfer kernels (TE, F) of the p-class extensions TE, F : C1pF → C1pE from F to unramified cyclic degree-p extensions E/F are shown to be capable of narrowing down the number of contestants significantly. By determining the isomorphism type of the maximal subgroups S G of all 3-groups G with coclass cc(G) = 1, and establishing a general theorem on the connection between the p-class towers of a number field F and of an unramified abelian p-extension E/F, we are able to provide a theoretical proof of the realization of certain 3-groups S with maximal class by 3-tower groups of dihedral fields E with degree 6, which could not be realized up to now.展开更多

These invariants have proved to be a valuable information for determining the Galois group of the second Hilbert p-class field and the p-capitulation type of K. For p=3 and a number field K with elementary p-class group of rank two, all possible IPADs are given in the complete form of several infinite sequences. Iterated IPADs of second order are used to identify the group of the maximal unramified pro-p extension of K.展开更多

However, few studies have investigated how both EFL teachers and learners view and analyze situations in which learners are not producing enough spoken language in class, and the reasons behind them. The present study will pinpoint the significant role of lexis in Moroccan learners＇ speaking production. To this end, 40 EFL teachers and 200 Moroccan high school students are surveyed and interviewed to reveal their perceptions of the speaking skill and the corresponding high significance of lexis in this instance. Results show that both teachers and learners identify vocabulary deficiency as the main factor behind students＇ inability to speak English. In the present paper, among the many suggestions that could be proposed to deal with this situation, it is argued that one efficient way would be to assist the students during the process of L2 （second language） vocabulary learning through vocabulary learning strategy instruction. Pedagogical and research implication will be given in response to the difficulties encountered in this area as have been identified by the EFL teachers and learners surveyed.展开更多

Customers arrive at stage-Ⅰ system in batches according to a Poisson process, and the size of the batch, x , is a r. v. within a range of a finite number of positive integers. The stage- Ⅱ ststem has finite capacity, where customers are served in batches with a PH-distribution and the size of the batch is a positive integer r. Only after served in stage- Ⅰ system, and then served in stage- Ⅱ system, can the customers depart from the whole system. Several definitions such as the stage- Ⅰ service blocked time, the first-class and the second-class batch waiting times, and the batch sojourn time are introduced, and their distributions are obtained respectively.展开更多

文摘Let F be a number field and p be a prime. In the successive approximation theorem, we prove that, for each integer n ≥ 1, finitely many candidates for the Galois group of the nth stage of the p-class tower over F are determined by abelian type invariants of p-class groups C1pE of unramified extensions E/F with degree [E : F] = pn-1.

文摘Given a fixed prime number p, the multiplet of abelian type invariants of the p-class groups of all unramified cyclic degree p extensions of a number field K is called its IPAD (index-p abeliani- zation data). These invariants have proved to be a valuable information for determining the Galois group of the second Hilbert p-class field and the p-capitulation type of K. For p=3 and a number field K with elementary p-class group of rank two, all possible IPADs are given in the complete form of several infinite sequences.
