查询词典 ground cover

Lid landing gear box body is formed with the motor gearbox. When the furnace cover needs opening , simply press the button in the control box then the furnace cover will descend at a uniform speed .For the sake of safety ,two movements institutions tops trip switch are mounted in the carburizing EAF .When the furnace cover is ascending , the lower movements institutions tops trip switch will automatically cut off the seepage carbon EAF control cabinet main circuit power supply, forcing the heating elements stop working since the power is cut off, The upper switch is used to restrict the height of the movements axis ,it can prevent the movements pumped up too high to cause theelevating screw abscisicing from the gear box.

炉盖升降机构由电机齿轮箱组成，当需要开启炉盖时，只需按下控制箱上的按组，炉盖即以均速上升下降，为了安全起见，在渗碳电炉升降机构上装设有两个行程开关，当炉盖上升时，下边的行程开关自动切断渗碳电炉控制柜主回路电源，使加热元件断电停止工作，上边的行程开关则限制升降轴升起的高度，以防升降抽升起过高，升降丝杆脱出齿轮箱。

These antennas can cover GSM900/DCS/PCS/UMTS operation. In the chapter 2, the antenna is designed based on the concept of monopole antenna. Furthermore, the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching. In addition, to raise distance between radiation plane and ground will avoid capacitative effect effectually. In the chapter 3, the antenna is designed based on the concept of planar inverted-F antenna. Furthermore, that the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching is similar to chapter 2. But there is a difference in them. We can choose the short position to change input impedance at this structure. In the chapter 4, the antenna is designed based on the concept of planar inverted-F antenna which takes coupled-fed. It will produce the first mode and high-order mode near the frequency, 900MHz. The feature of this type is to reduce the volume effectually. This antenna can not only cover GSM900/DCS/PCS/UMTS operation but maintain good radiation efficiency. Finally, we will compare three antennas, and develop procedure with industrial view, and propose the prospect of the GSM/GPRS antenna in PND, as a conclusion.

在第二章中，我们使用单极天线设计概念，使用双路径架构并於末端耦合来对天线阻抗做匹配，产生涵盖GSM900/DCS/PCS/UMTS四频操作频带，并提高与接地面的辐射高度，以避免电容效应，使天线具有良好的辐射特性；在第三章中，使用倒F形天线设计概念，使用双路径架构於末端耦合，并於辐射臂上采取适当接地点电感效应作输入阻抗匹配，达成涵盖GSM900/DCS/PCS/UMTS系统的四个操作频带；在第四章中，采用倒F形架构并使用耦合馈入方式，使得长辐射金属臂在低频900 MHz附近产生共振，产生低频基频模态及高阶模态，以达成宽频及频宽涵盖GSM900/DCS/PCS/UMTS频带操作，并有效缩减使用体积；最后，分别比较此三种架构的优缺点，再加以业界角度来思考，研发产品天线的流程及思考方向，以及天线应用於可携式导航装置中未来的展望作为本论文的总结。

And the housewife took the cover and spread it over the cistern, strewing ground grain on the cover so that nothing could be noticed.

那家的妇人取了一个盖子盖在井口上，盖子上又撒上了些麦粒，免得有人注意。

Replant damaged ground as soon as possible since erosion caused by loss of ground cover can lead to flash flooding and additional landslides in the near future.

尽快重新在受损的土地上种植植被，因为地面植被受损造成侵蚀可能导致在不久的未来发生暴洪及额外的山崩。

They clutch at everything: a bush is a point of support; an angle of the wall offers them a rest to the shoulder; for the lack of a hovel under whose cover they can draw up, a regiment yields its ground; an unevenness in the ground, a chance turn in the landscape, a cross-path encountered at the right moment, a grove, a ravine, can stay the heel of that colossus which is called an army, and prevent its retreat.

我们对任何一点东西都不肯放松；一丛小树可以作为据点，一个墙角可以成为支柱，背后缺少一点依靠，可以使整队人马立不住足；平原上的洼地，地形的变化，一条适当的捷径，一片树林，一条山沟，都可以撑住大军的脚眼，使它不后退。

The house's environmental performance is passive and uses basic sustainability ideas: electrically operated skylights exhaust hot air using a chimney effect in the double height space – and keep warm air inside during winter, insulation is optimized, underfloor heating is provided on ground level and the outside landscape uses a low water xeriscape approach, with a mostly gravel ground cover suitable for the desert location.

Based on the split window method, the classification of the ground land cover types, and the given spectral emissivities range in thermal infrared bands for each ground class and the fact that the actual land surface temperatures are the same for all thermal bands of MODIS, the land surface temperature were determined by means of maximum correlation and least square fit.

The results indicate, the ground state energy increased quickly as the decrease of ZnO QD radius, when the radius decreased to the effective Bohr radius of ZnO exciton (aB=1.8nm), the ground state energy is 488meV higher than the conduction band bottom, about 8 times of binding energy of ZnO free exciton. When the radius is larger, the ground state energy inclined to a constant (under conductor bottom about 65meV), approximate the binding energy of the exciton in bulk crystal ZnO.
