This method is most special is the principle of simple and clear, setting out the process visible and tangible, it is applicable to a little bit knowledge of sheet l scene lofting geometry, which is a revolutionary approach, which not only greatly reduced the mapping workload, but also a great convenience in construction. Same time, it can also be a more traditional method (open show diagram drawing or galvanized sheet cut oil felt like, after re-opening in the pipe body gestures draw the cutting line method) is more accurate and pipe sections match exactly between the butt, thereby ensuring the steel fork tube and bend production quality.

该方法的最大特就点是原理简单明了，放样过程看得见摸得着，很适用于稍有一点几何常识的钣金工现场放样，这是一革命性的方法，它不仅大大地减少了制图工作量，而且也极大方便快捷了施工，同时它还可较传统方法（绘制开口展图后用油毛毡或镀锌板裁样再后在管身上比划绘出开口切割线的方法）来得准确无误与管段间对接严丝合缝，进而保证钢岔管和弯头的制作质量。

The axial profiles of the worm thread at different sections can be obtained from the gear geometry, lofting the profile curves produces the NURBS (non-uniform rational B-spline) surface of the worm surface.

轴向剖面蠕虫线程在不同路段可从齿轮几何学放样的轮廓线产生的NURBS表面的蠕虫表面。

Therefore, the 3S technologies are fully applied in the area. On one hand, remote sensing mapping and digital elevation modeling are used to realize highprecision seismic data acquisition and quality control of field operation. GPS control points are emplaced through "firstorder control, survey grid placement stepbystep and overall adjustment", and surface fitting technique is used to build a digital model with regional height anomaly corrected. The GPS RTK and fullstationequipment traverse survey are used to realize the lofting survey of shooting and receiving points. The height fitting of shooting and receiving points of the GPS RTK survey is realized through correcting the digital model with regional height anomaly.

为此，全面地采用了3S技术，一方面从总体上运用卫星遥感影像成图技术和数字高程模型系统，实现室内对地震勘探的精确设计和对野外施工质量过程监控；用GPS卫星定位技术采取&首级控制、分期布网、首分网整体平差&方法布测物探GPS控制点，采用曲面拟合技术建立区域高程异常改正的数字模型；应用GPS RTK和全站仪导线测量等方法实现激发、接收点放样测量，利用区域高程异常改正数字模型对GPS RTK测量的激发、接收点进行高程拟合。

After the introduction of S750, only the standard linear design documents through the SD card or USB data cable into the S750, make lofting lines can accurately indicate the location of lines in the field, but also in the setting-out data interface Acquisition of high-precision.

在采用S750后，只需将标准的线型设计文件通过SD卡或USB数据线导入到S750中，进行线路放样，既可精确地指示出线路在实地的位置，还可在放样界面进行数据的高精度采集。

By the end of 1997, from the Qinghai oil sand long-chuen finish sub-region measured gravity points lofting a few days later returned to Xi'an, I follow the squadron to shadow whirling coconut Wanning City in Hainan to engage in the standard of measurement, it is heard that China and Australia a cooperation project.

1997年底，从黄沙漫漫的青海油泉子地区干完重力点放样测量回到西安没几天，我跟随中队到了椰影婆娑的海南岛万宁市从事进行水准测量，听说是我国与澳大利亚的一个合作项目。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.

在大学的三年的学习生活不仅给予我自身的充实，更重要的是磨练和培养了我较强的自觉能力和严谨，踏实的作风以及不怕困难的精神，对未来充满了信心！

As the first volcanoes erupted, one of the gases that bellowed out was steam.

在第一批火山喷发时，喷出的气体之一就是水蒸汽。
