Under the given condition of acoustic driver, the acoustic field including oscillating pressure, volume flow rate and acoustic impedance in resonator was theoretically reconstructed by using the two-microphone method. The experiment results validate that this method is applicable and accurate for the positions with non pressure antinode and node in resonator. The maximum errors near antinode and node area are up to 12.4%.

This paper combines with pipeline delivery of our countrys actual conditions and other methods of detection and location. To the leakage characteristic of the fault to the long-distance natural gas pipeline, a method is raised, which is on the basis of wavelet and negative-pressure-wave to detect the leakage and locate. Jobs in this paper are as follows:Multi-resolution decomposition and reconstruction of wavelet transform is utilized to filter the noises, which the leakage brings the noises of negative-pressure-wave. The research is worked in the wavelet and wavelet packet filter. The wavelet transform have a fast and accurate recognition capability to signal singularity. This paper chooses wavelet technology to catch the break point of pressure signal.

Examination of the equilibrium status of a point in the salt water zone and the description of piezometric heads at two points in both the salt water and fresh water zones reveals that the location of the fresh water-salt water interface in a coastal homogeneous, isotropic unconfined aquifer can be estimated based on piezometric heads at two points in the same vertical line tapping respectively the salt water zone and the fresh water zone (from the water table to the interface) when the groundwater flow system is in a steady state and satisfies the Dupuit assumption.

In this thesis, the influence of column force, joint hoop reinforcement, and repeat load on the stress and sheer bearing capability of inclined pressure bar is analyzed utilizing finite element software. In the case study, the column axial force's influence on the inclined pressure bar's equivalent width, stress and sheer bearing capability of RCFEN is obtained by changing the column force when modeling the RCFEN with ANSYS. In the former model, the joint hoop reinforcement influence on the equivalent width inclined pressure bar and the strength of RCFEN is achieved by changing the quantity of joint hoop reinforcement; the inclined pressure bar's equivalent width and the strength variation of RCFEN under cyclic load are gained by applying low frequency cyclic load on the inflection point of column and the middle of beam.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
