We analyzed the air gun signals in the 185Km-long seismic line. And the records showed that the air gun signal is full of seismic phase information. Based on these phases, we developed the P-wave velocity model for this area and find an obvious low-velocity layer, which is coherent to what people obtained from other geophysical methods in this area.

我们分析了气枪激发信号在长185km测线上的记录，拾取包含的丰富震相信息(如Pg，Pn，PmP等)，并在此基础上反演了该地区的P波速度模型，模型结果显示该地区存在明显的低速层，这与在该地区进行的其他地球物理探测结果一致。

The process of sand absorption is:(1) the vibration head vibrates and losses the sand layer, and supply high pressure air into the sand absorption head;(2) the high pressure air generates negative pressure in the sand absorption pipe when it is discharged out from the sand absorption;(3) the sand absorption head and the vibration are shifted downwards and maintains the water flow straightly.

取砂土的过程为：(1)振动头振动松散砂土层，同时向吸砂头供入高压空气；(2)高压空气通过吸砂头从排砂管向上排出的过程中，在吸砂管内产生负压，吸砂管将管口处的水和砂土吸入到吸砂头内，在高压气流作用下，吸砂头内的砂、水和气混合而成的三相流通过排砂管排出到受砂船上；(3)在吸砂的过程中，适时地将吸砂头和振动头下移并保持钻孔套管中的水流畅通。

In allusion to the problems existing in using medium pressure air as drilling fluid under the conditions of breccia formed by small structural action, loose coal layer and unstable formations, new type of drilling tools and bits was designed. The mechanism of cutting removal by air media was stated and analyzed.

在针对小构造带形成的角砾岩、松散煤层、不稳定地层等瓦斯地质条件下，采用中压风作为冲洗介质进行钻探中所存在的问题，重新设计了新型的钻具级配、正反向一体化钻头等，并且对风介质的排渣机理进行了阐述和分析。

By using global reanalysis data from NCEP/NCAR,the durative of a floating dust over Beijing during 7-10 in April of 2006 was analyzed.It was found that the impact systems of the floating dust weather were West Siberia cold eddy,Okhotsk warm high and Tibetan Plateau high ridge at the level of 500 hPa;the dry-cold air at the level of 700 hPa transferred to Beijing ceaselessly,and the cold advection and baroclinic instability were strong,the gale and dust storm occurred in the strong cold advection area;the weak instability stratification in surface layer and mid-low level in the south of North China resulted in weak ascending air flow,then transported dust particles to Beijing depending on the easterly wind in front of the surface low pressure.

文章摘要：使用NCEP/NCAR再分析资料对2006年4月7-11日北京浮尘天气过程的持续性进行分析，指出此次浮尘天气过程主要受500 hPa西西伯利亚冷涡、鄂霍次克海暖高压以及青藏高原高压脊影响；700 hPa有干冷空气不断向北京地区输送，冷平流和斜压性都很强，大风和沙尘暴发生在强冷平流区域；由于华北南部地区近地面至中低层存在弱的不稳定层结，容易产生弱的上升运动。
