In this paper,Laterite soil adjacent to some stake of the highway in Chenzhou, Hunan section from Xiamen to Chengdu was used to investigate the deformation characteristics and protection methods of the Laterite soil subgrade under the influence of environment factors.Properties like water-holding capacity,capillary rise, coupled heat-moisture transfer and wetting deformation of samples under different compactness were studied through a series of laboratory tests.In addition,by using meteorological data of two consecutive years in Chenzhou,coupled process of moisture transfer and subgrade deformation was stimulated under the impacts of groundwater and the atmosphere.Specific work done in this paper is as follows:(1) Samples under different compactness were subjected to a series of conventional laboratory tests,such as permeability,consolidation,contraction,shear test and etc.

论文以厦门至成都高速公路湖南郴州段的红粘土为研究对象，以环境因素作用下红粘土路基的变形特征与防护方法为研究目的，通过室内试验研究了不同压实度红粘土的持水性能、毛细上升、湿热耦合迁移及湿化变形等特征，借助郴州地区连续两年的气象数据，模拟在地下水和大气的共同作用下路基内部红粘土水分迁移与路基变形的耦合过程，主要研究内容及结论如下：(1)针对不同压实度的红粘土，系统开展了其渗透、固结、收缩、剪切等试验研究。

Additionally, poor sealing effect will also change the oxygen content in the bottle. Selecting a capper and caps that have excellent pressure quality can solve this problem.

另外，封盖时密封效果不好也会引起瓶中含氧量的变化，只要选择压盖质量较好的压盖机和合格的盖子就可有效解决这一问题。

AYG full-automatic capper can be used on tighten all kinds of plastic bottle cap.

The filling process naturally causes an increase in oxygen content, including the remaining oxygen after vacuum filling (particularly for the bottle itself has not been purged or purged inadequately). This oxygen in the filling machine liquid tank and air content in the bottle neck enters the capper.

灌装过程造成的含氧量增加，包括抽真空后（特别是未经抽真空或只经一次抽真空的瓶子）瓶中的部分残留氧、灌装机贮液缸中的氧及灌装完成并卸压后瓶子离开灌装机进入压盖机的过程中瓶颈空气的含量。

Excessive formation back pressure may be due to limited or plugged perforations; subsurface or surface chokes; undersized gas-oil separator, flowlines, tubing, or casing; or excessive back pressure on flowline, casinghead gas gathering system, or gasoil separator.

The main jobs of the paper are as follows, Multi-scale decomposition and reconstruction of wavelet transform is utilized to filter the noise of negative-pressure-wave, which is brought by leakage. With the capacity to detect the signal singularity quickly and accurately, wavelet transform was used to catch the break point of pressure signal. Accordingly, the work improved the location accuracy.

主要研究工作有：利用小波变换的多分辨率分解和重构技术，对采集到的管道泄漏产生的负压波信号进行消噪处理，并对几个影响消噪质量的关键因素及其选取方法进行了分析；再利用小波变换技术对信号奇异点的快速、准确的识别能力，对经消噪后的负压波信号进行奇异点捕捉，从而实现更精确的单条燃气管道泄漏定位。
