纬差

我国基本比例尺地形图是以国际百万分之一地图分幅为基础，按一定的经差和纬差划分图幅。

Basic scale topographic map is bases on one of million international map subdivision and divided by Longitude difference and Latitude difference .

北太平洋纬向热力差对长江中下游梅雨的影响

The influence of zonal thermal difference over North Pacific on Meiyu in the middle and lower Changjiang Valley

近29年长江中下游入梅期、梅雨量和出梅期各指数与前期各月的北太平洋海温场的相关普查，显示出各梅雨指数首先和当年初夏北太平洋海温场的纬向热力差有关。

Calculating the correlation field between the indices of Meiyu in recent 29 years and sea surface temperature of North Pacific in preceding months , we have found that the indices of meiyu are related to the zonal thermal difference of the North Pacific in early summer .

川滇地区地震时的月日赤纬及黄经差特征比较

A Comparison of the Characteristics of Co-seismic Lunar-solar Declination and Ecliptic-longitude Difference between Yunnan and Sichuan

表、里层织物纬纱分别采用PET和PTT长丝，利用两层织物不同的纬向收缩率，形成表、里层具有纬向长度差的双层机织物结构。

Outer and inner layers respectively uses PET and PTT filaments as weft , and make use of the different weft shrinkage to form the bilayer woven fabric structure with different weft length in inner and outer layers .
