应以路线固定表和曲线要素表中的原始数据为基准推算坐标才会得到更高精度的数据，精确指导施工。
Should regard initial data in the charts of route location and curve elements as datum that coordinates calculate will just get the datum of high accuracy, Guide constructing accurately.
在分析了线性参照系统概念模型的基础上，对其中两个关键问题进行了研究，即基于道路几何特征的线性参照基准模型和基于道路曲线要素的动态分段模型。
In this paper, a linear referencing system based on road line-shape is presented in order to reduce spatial data redundancy and protect road event from going out of road range.
等产量线是表示两种生产要素的不同数量组合可以带来相等产量的一条曲线。
Isoquant curve is a line showing all the alternative combinations of two factors that can produce a given level of output.
而如果行业的要素供给曲线是正斜率的话，所有厂商就不可能在价格不变的情况下同时得到更多的生产要素。
But if factor supply curves to the industry slope positively, all firms together cannot get an increased quantity of factors of production at an unchanged price.
现在，也许可以认为行业面对的这些要素的供给曲线是水平的。
Now it may be that the supply curves to the industry of these factors can be taken as horizontal.
因此，同时沿着MC曲线移动与假设的生产要素供给条件是相矛盾的。
Simultaneous movement along the MC 'curve is therefore inconsistent with the assumed conditions of supply of factors of production.
另外，就作为一个整体的行业而言，将其可变要素供给曲线视为水平线之所以是恰当的，还有其他理由。
For the industry as a whole, there is another reason why it might be appropriate to regard the supply curves of the variable factors to the industry as horizontal.
用圆弧投射法解决圆锥曲线与其它空间几何要素的相互位置问题，可使作图更为简练、精确。
By using circular arc project, the relative positions of the conic curves and other spatial geometrical elements can be solved for simplified and precise drawings.
这种情况可能出现，其理由恰与上面关于单个厂商的要素供给曲线为水平线的理由一样。
This may be so for precisely the same reasons as are adduced for regarding the supply curve of a factor to an individual firm as horizontal.
早期的质量成本曲线只是定性的描述了质量成本各组成要素间的关系，为最低点的求解提供了思路。
The curve of the quality cost has qualitatively described the relationship of the factors in the quality cost in the past years, and provided clues for calculating the lowest cost.
等产量线是表示两种生产要素的不同数量组合可以带来相等产量的一条曲线。
Isoquant A line showing all the alternative combinations of two factors that can produce a given level of output.
这个讨论提出了要素供给曲线的含义问题，但我们在此不予说明。
This discussion raises problems about the meaning of the supply curve of a factor that we shall waive here.
注意，上述第三点是要求特定群体面临的生产要素供给曲线保持不变。
Note that item 3 holds constant the supply curves of the factors of production to the specific group.
非圆曲线轮廓是机械零件常见的轮廓要素之一，绝大多数数控机床只具备直线插补和圆弧插补功能。
Non-circle curve is one of familiar outlines, but most numerical control machine tools only have linear interpolation and circular interpolation.
学习曲线所描述的是企业累积性产品产量与每一单位产量所需要投入要素数量之间的关系。
Learning curve a graph showing the mathematical relationships between the quantity of firm's accumulative product and that of input to every unit of product.
学习曲线所描述的是企业累积性产品产量与每一单位产量所需要投入要素数量之间的关系。
