雨养农业 meaning in English
rainfed farming
Examples
- The mean bulk momentum transfer coefficient cd and bulk sensible heat transfer coefficient ch is 3 . 37 * 10 - 3 and 4 . 47 * 10 - 3 , which is slightly larger than that above desert gobi and grassland of plain and little than that above plateau . on one hand , the more unstable atmosphere is , the larger bulk transfer coefficients are under unstable conditions , on the other hand , and bulk transfer coefficients decrease as wind speed increases
动量和感热总体输送系数的平均值分别为3 . 37 * 10 ~ ( - 3 )和4 . 47 * 10 ~ ( - 3 ) ，略高于沙漠、戈硕士学位论文:半干早雨养农业区陆面过程观测试验研究壁及平原草地的值，而低于高原的值;在不稳定时，层结越不稳定，总体输送系数也越大，并且随风速的增加而减小。 - The maximum of instantaneous global radiation is beyond 1000w / m2 and the ten - days average intensity is 338 . 90w / m2 because of high atmospheric transparency over semi - arid rainfed agriculture region of loess plateau between june and august . global radiation , reflected global radiation and surface long wave radiation emerge the characteristic of daily variations on a typical clear day and cloudy day , whereas atmospheric long wave radiation has not this characteristic . meanwhile , net radiation , latent heat flux sensible heat flux and soil heat flux appear the same characteristic as the mean daily variations above spring wheat field and bare soil on a typical clear day and cloudy day
黄土高原半干旱雨养农业区夏秋季大气透明度较高，晴天地面的总辐射值最大瞬时值均超过1000w m ~ 2 ， 6 8月总辐射旬平均强度为338 . 90w m ~ 2 ；典型晴天和阴天总辐射、反射辐射、地表长波辐射均表现出明显的日变化特征，而雨天没有明显的日循环规律；无论是晴天、阴天还是雨天，大气长波辐射基本没有明显的日变化规律。
