It is usually needed to construct large scale underground projects for water power utilization in this area 受地形條件的限制,開(kāi)發(fā)這些地區(qū)的水能資源往往需要布置大規(guī)模的地下廠房洞室群。
An anticlockwise gyre near the kuroshio north of japan inland is simulated using a high - resolution topography 在高分辨的地形條件下,日本西海岸外側(cè)的黑潮北部存在一逆時(shí)針?shù)鰷u,這可能與該區(qū)域的漏斗型地形誘導(dǎo)有關(guān)。
D resistivity inversions under the condition of uneven terrain are presented in this study , and several methods for erasing topographic influence in the inversion are discussed 摘要本文實(shí)現(xiàn)了非平坦地形條件下電阻率三維反演,討論了幾種消除反演中地形影響的方法。
Due to the special relief in narrow mountainous zone , as well as the high cost of and the difficulty in applying separate tunnel line , twin - arch tunnel is adopted 在山區(qū)狹窄地帶等特殊地形條件下,采用分離式隧道線路較為困難且造價(jià)高昂,于是產(chǎn)生了雙連拱隧道形式。
- 1 with high exactness and good applicability which can output military digital map and make analysis of terrain condition , is the foundation of developing the system 建立一個(gè)精確度高、通用性好的軍用數(shù)字化地形圖生成及地形條件分析模型,是戰(zhàn)術(shù)訓(xùn)練模擬系統(tǒng)開(kāi)發(fā)的基礎(chǔ)。
Large - eddy simulations are carried out for the adjustment of convective boundary layer over heterogeneous surfaces . simulations are confined for zero mean - wind and flat terrain . surface heat - flux is set varying in 研究限于無(wú)風(fēng)平坦地形條件,地面熱通量在一個(gè)水平方向作非均勻變化平均地面熱通量為0 . 15kms
When constructing senior highways in china , the project of twin - bore tunnel is often adopted in special geologic and topography districts in order to get better technological and economical purpose 我國(guó)在高等級(jí)公路的建設(shè)中,在特殊地質(zhì)及地形條件的地區(qū),為獲得良好的技術(shù)經(jīng)濟(jì)效果,大量選擇了連拱隧道方案。
Considering the port geological structure , landform , hydrology and investment conditions , the degree of the incline must be small . passengers must go across a long incline when they get on or down the ships 考慮到其港區(qū)地質(zhì)構(gòu)造與地形條件,水文條件和投資條件等因素,港口碼頭在建造時(shí)坡度都取值較小,乘客上、下船要走過(guò)坡道距離較長(zhǎng)。
According to the robots ' requirement of working on the complicated terrain and the configuration and correlative parameters of the mobile robot studied here , two detecting means of the position and pose of mobile robot ' s platform are researched here 根據(jù)移動(dòng)機(jī)器人在復(fù)雜地形條件下的工作要求以及所研究機(jī)器人的結(jié)構(gòu)特點(diǎn),設(shè)計(jì)了2種機(jī)器人平臺(tái)位姿檢測(cè)的方法。
Special analysis is made to see the impact of different boundary layer parameterization schemes on some factors which affect the heavy rainfall such as vertical velocity , divergence , vorticity , divergence of water vapor flux , se field and so on 結(jié)果表明:復(fù)雜地形條件下,特別是降水有明顯日變化的地區(qū),邊界層的作用是十分重要的,這在暴雨時(shí)的緯向垂直環(huán)流結(jié)構(gòu)中表現(xiàn)地非常明顯。
