以最新研制的LXⅡ型岩土工程质量检测分析仪为例，介绍了虚拟仪器（Ⅳ）技术思想在我国工程地球物理勘探仪器领域的应用现状。文中指出：虚拟仪器技术是工程地球物理仪器的发展方向。这一最新技术的采用，可使我国工程物探仪器真正做到小型轻便、一机多用，并可望尽快结束当前我国工程物探仪器生产各自为政、记录格式五花八门的松散状况，使其生产规范化、记录格式统一化。 Taking the newly developed LX Ⅱ geotechnical engineering quality testing analyzer as an example, the application status of virtual instrument (Ⅳ) technology in engineering geophysical prospecting equipment in China is introduced. The article points out: Virtual instrument technology is the development direction of engineering geophysical instruments. The adoption of this latest technology can make our geophysical prospecting equipment truly small-sized and portable, and it is expected to end as soon as possible the fragmentation of current geophysical prospecting equipment in our country. The format of the geophysical and geochemical surveying instruments is varied and varied so that its production standardization and recording format standardization.
