| 5. | The result indicated that the diurnal changes of net photosynthetic rate ( pn ) of cynanchum komarovii displayed significantly less symmetrical two - peak pattern , with a predominant peak in ll : 00am and a small peak in 16 : 00pm . on hot bright sunny day
结果表明： 1 、在夏季晴朗天气条件下，牛心朴子光合速率日变化呈现双峰现象，第一峰出现在上午11 ： 00左右，第二峰出现在16 ： 00左右，第一峰值明显高于第二峰值。 |
| 6. | The diurnal change of cg lightning is obvious , and it generally takes on bi - peak and bi - valley pattern . the two peak values occur at 15 : 00 and 03 : 00 respectively , whereas the two valley values occur at 09 : 00 and 22 : 00respectively . the mean current of positive cg lightning is slightly bigger than that of negative one
闪电的发生也有明显的日变化，总体呈双峰双谷形式， 15时和03时为两个峰值，两个谷值分别出现在9时和22时。 |
