地质勘探

As one kind of sensors, geophone is widespread used on oil, geology detection and engineering survey.

地震检波器作为传感器，被广泛地应用于石油、地质勘探、工程测量等领域。

Minerals found in the region has 31 major categories, representing the province's mineral resources have been found in 23% and found that more than 160 types of mineral point, the proved reserves of 15 kinds of minerals, of which: ilmenite, graphite ore are domestic large mineral reserves of 6,000,000 tons and 4,000,000 tons or more; limestone, gypsum, Glauber's salt, granite and coal and other non-metallic fuel and energy resources in the northwest edge itself, which proved coal reserves of 1.068 billion tons, oil-page rock 248 million tons, 7.73 million tons of Glauber's salt, 1.17 billion tons of limestone, gypsum 140 million tons, due to a low degree of geological exploration, the comprehensive development of a low utilization rate, at present the development and utilization of mineral ores accounted for only 30% of the region, cooperating with the outside great potential for development.

全区已发现矿产9大类31种，约占全省已发现矿产的23%，发现各类矿产点160余处，探明储量的矿种15种，其中：钛铁矿、石墨矿属国内特大型矿产，储量分别为600万吨和400万吨以上；石灰石、石膏、芒硝、花岗岩和煤炭等非金属和能源燃料类资源在西北占居优势，其中煤炭探明储量10.68亿吨、油页岩2.48亿吨、芒硝773万吨、石灰岩11.7亿吨、石膏1.4亿吨，由于地质勘探程度低，综合开发利用率低，目前开发利用的矿种仅占全区矿种的30%，对外合作开发潜力巨大。

The graphic method of probability is an effective tool in the field of exploration.

概率图解法是解决地质勘探问题的一种快捷、便利、高效的辅助工具。

The project is scheduled to run in 2012. The Jinping auxiliary tunnels (2×17.5 km) serve as the access tunnels between Jinping Ⅰ and Jinping Ⅱ, and also as the exploratory and construction adits for the headrace tunnels of Jinping Ⅱ.

锦屏水电站计划于2012年第一批机组投入运行。2条长17.5km的锦屏辅助洞是联系锦屏一、二级水电站的交通洞，也是锦屏二级水电站引水隧洞施工的超前地质勘探洞和施工辅助洞。

Risk management can offset the uncertain factors throughout the project such as inaccurate core sampling, incredibility of the contractor, etc.

因为，公路工程项目从立项到运营都存在许多不确定因素，如设计过程的地质勘探取样失真、施工过程中承包商的信誉等，这些不确定因素会使得原定计划、方案受到干扰，使原定的目标不能实现。

The area reversed intensively in Late Cretaceous and Paleocene, so as to form a series of fault basins, which created a two-layer structure in the upper crust of the Lower Yangtze area.

这是造成下扬子地区海相古生一中生界油气地质勘探高复杂性、高难度性和高风险性的根本原因，也造就了下扬子区海相烃源岩的二次生烃和晚期成藏的优势。

In the end, the exploration data about one Open Pit of Xiandewang coal mine are taken as an example to test the function, validity, security, practicality and operability of the 3D visualization system.

最后利用显德旺煤矿露天矿区的地质勘探资料，对开发出的煤矿三维可视化系统的可运行性、正确性、健壮性、安全性、实用性及易操作性等进行分析验证。

Therefore, careful pre-, hydro-geological exploration of science is very necessary.

因此，前期的认真、科学的水文地质勘探工作是非常必要的。

Do you expect me to give my whole life up to geological prospecting?

你希望我献身于地质勘探吗？

The estimation of signal parameters is an important research field of modern signal processing. It finds wide applications in many fields, such as radar, communications, sonar, seismology, radio astronomy, biomedicine engineering, etc. So, its study is of great theoretical and practical value.

信号参数估计是现代信号处理领域内一个重要分支，它在雷达、通信、声纳、地质勘探、射电天文以及生物医学工程等众多领域有着广泛而重要的应用前景，因此对各种参数估计方法的研究有着重要的理论和应用价值。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
