邻近性 meaning in Chinese
propinquity
Examples
- A pulse hard source has been adjusted to allow the reflection wave pass by the source without retroreflection . and the calculation area is changeable at the different time step , so only those area with wave propagation have been calculated . as the results , the total calculation time can be reduced
还有计算区域随时间改变的方法，利用fdtd计算空间点的邻近性，在不同的时间步上计算不同大小的区域，使得只有波传播到的区域被计算，这样可以缩短计算时间。 - The present paper probes into three of these dimensions , namely , the enterprise - manufacturer , industry - trade and region - zone dimensions , arguing that spatial agglomeration is characterized by business growth and spatial expansion on the first dimension , with its functional mechanism embodied as internal economies of scale and scope ; by adjacency of enterprises on the second dimension , with its functional mechanism being external economies of scale and scope ; and by regional integration of the industry as a whole on the third dimension , with it functional mechanism being regional external economies of scale
文章从企业厂商、产业行业和区域地带三个尺度研究了经济活动空间集聚，认为在企业厂商尺度上，空间集聚特点是企业增长和空间扩张，作用机理是内部规模经济和内部范围经济；在产业行业尺度上，空间集聚特点是企业的空间邻近性，作用机理是外部规模经济和外部范围经济；在区域地带尺度上，空间集聚特点是产业的区域复合，作用机理是区域外部规模经济。
