The next point to be staked is a common issue in the GPS RTK staking. It is proposed in this paper that the coordinate of a certain point be used to determine its direction and perpendicular distance from the road center.

在GPS RTK道路中线测设时，常遇到下一个点在何处的问题，做法是随测一个点的坐标，反算出该点趋向道路中线的方向与垂距，在行进之中，实现导向与导距。

The current photoelectric servo gauge-alignment system is replaced by laser video camera gauge-alignment system.

以激光摄像式轨距-轨向系统替换现有的光电伺服式轨距-轨向系统。

Transformation of geographic coordinates to plane coordinates eastings and northings or x,y

将地理坐标变换到平面坐标（东距和北距，或称作x和y）。

If the instrument is subjected to torsional loads, the shear stress at every cross section is proportional to the torque and the radical distance from the bars axis, and is inverse proportional to the polar moment of inertia of the cross section.

扭转载荷下，横截面某点的切应力与扭距成正比，与到截面中心的距离也成正比，与横截面的极惯性距成反比。

The first step is selecting a rain gauge as rainfall center by taking turns and adding the nearest rain gauge step by step to estimate the rainfall ratio relation of the same time with respect to the different distance separately. The last step is utilizing Weibull function can inquire into the return periods. Then, the ARF of Tamshui River basin is established.

研究中，先以某个雨量站当成点降雨中心，并逐次纳入邻近雨量站，即可分别得到不同距离下、同时间之雨量比值关系，依序置换不同雨量站为中心进行相同之分析，并利用威伯点绘法，进一步推求重现期距，即可建立研究区域之不同重现期距、不同延时与面积递减关系之ARF曲线。

The approximate solution shows that there is a rectilinearity in the pressure and time semilogarithmic coordinates.

注水井压降试井的近似解表明在压力与时间的半对数坐标下呈直线关系，直线的斜率与截距取决于注采比、注采井距、注采厚度比、注采产能系数比等参数。

The results are much better than the other approaches'. Then we give another method for approximating offset curves. The circle is first approximated by regular polygon within some tolerance. The exact offset curve is then approximated by the convolution of the regular polygon with a B-spline curve or a NURBS curve having the same degree.

与此同时作者从基圆的正多边形逼近出发，通过求解包络的技巧给出了等距曲线逼近的另一个算法，可整体估计误差，所得的等距逼近曲线为与基曲线同次数的B样条或NURBS曲线，克服了国际上现有同类算法中逼近曲线次数几倍于基曲线次数的缺陷。
