| 1. | Grey interaction analysis of mine inflow growth of meiyukou mine 煤峪口矿矿井涌水量的灰色关联分析 |
| 2. | Reasons and prevention for spontaneous combustion in slicing faces of meiyukou coal mine 煤峪口矿分层工作面自然发火原因及预防 |
| 3. | Go by car the route : the city is super - speed - village - of good country - - river scenic area of north town - - saint mountain 乘车路线:京石高速-良乡-阎村-坨里-河北镇-贾峪口-圣莲山风景区 |
| 4. | Abstract : based on the simulated laboratory experiment of pressure balance for fire extinguishing , the pressure regulating technique in the burning section of meiyukou coal mine is summarized 文摘:在采场均压防灭火实验室模型模拟实验的基础上,总结了煤峪口矿现场实施火区的调压工艺技术。 |
| 5. | ( 2 ) the method of time series analysis and the stochastic models are introduced , and the yearly and monthly runoff series stochastic models at the heiyukou gauging station in heihe river are established and checked ( 2 )对水文系列的时间序列分析方法及常用的随机模型进行了阐述,建立了黑河黑峪口站的年、月径流序列生成模型并进行了检验。 |
| 6. | At the same time the highway ecosystem assessment model is set up . then the changes of the ecosystem state is considered under the pressure and the response - pressure in the construction period and the run period of the expressway . at last the paper explored the example of the highway from laoyukou in hu city to huaishuguan in yang city 同时建立了高速公路生态系统评价模型,分别考虑在压力作用下以及在响应、压力作用下,高速公路建设期和运营期的道路生态系统变化,最后结合西汉高速公路户县涝峪口至洋县槐树关段加以实证分析。 |
| 7. | On the basis of theoretical studies and discussion , combining the construction of the forest resource investigation management information system of ningxia forest information platform , we selected suyukou manage station of ningxia helan mountain nature protect bureau as an example and realized the automatic and remote user authority management of forest resource second class investigation data 在理论研究和讨论的基础上,结合宁夏林业信息平台项目森林资源调查管理信息系统建设,选择宁夏贺兰山自然保护局苏峪口管理站为试点进行应用例证。实现了森林资源二类调查数据库的动态管理以及远程用户权限管理。 |
