查询词典 mean time

The results were as follow: At fine, cloudlet and cloud weather in rainy season,the mean value of CO 2 content varied in a range of 349 to 350ml/m\+3 at 2.8m above the canopy, 346 to 348ml/m\+3 at 0.8m above the canopy, 345 to 349ml/m\+3 at 16m inner the forest and 352 to 357ml/m\+3 at 5m above ground in the period from 9:00 to 18:00.The CO 2 content in rainy season was lower than that in dry season. At the same weather and space-time, CO 2 content in rainy season was higher than that of CO 2 in dry season at both day and night. According to the grads calculation, there were the CO 2 flux from atmosphere to canopy with 0.61×10 -6 and 0.71×10 -6kg/(m 2·s) during day time in dry and rainy seasons respectively.

采用梯度法及CI-301PS CO2系统，实现了海南尖峰岭热带山地雨林近冠层CO 2、微气象因子梯度观测研究，结果表明：雨季晴、晴间少云及多云天气，9：00～18：00CO 2浓度平均值分别在349～350ml/m3(冠上2.8m)、346～348ml/m3(冠上0.8m)、345～349ml/m3(林内16m)、352～357ml/m3(林内5m)，较旱季相应天气分别小14～17.5、10.1～23.7、1 6.4～35.7和18.1～36.1ml/m3；1：00～8：00，则雨季CO2浓度大于旱季；梯度浓度廓变量和实时动力计算反映出，8：00～18：00CO2通量由大气向林冠层，旱、雨季平均CO2通量分别为0.61×10-6kg/(m2·s和0.71×10-6kg/(m 2·s)，19：00通量甚微，20：00～7：00CO2通量则由林冠向大气，平均CO2通量分别为0.36×10-6kg/(m2·s)和0.32×10-6kg/(m2·s)；雨季昼夜大气流向冠层的净CO2通量是相应旱季的1.56倍。

There was one time when the whole nation has an upsurge of learning computer skills. Our factory also managed to give some lessons. Things like hard drive, RAM, keyboard, none of them I could understand. I didn't really mean to learn. In a small backward city like ours, the factory business is not promising. The salary of my wife and I put together can barely maintain the everyday life. Computer is an extravagancy that was too remote for us. I once believed that's something I could never afford to buy (about 10, 000 RMB for each at that time). Even if I could afford one, I was interested in it.

曾几何时，神州大地掀起了一股学习计算机的热潮，公司也组织过学习班，什么硬盘，内存，键盘我一个词也听不懂，我也没想学，在我们这样落后的小城，工厂也不景气，俩个人的工资只够维持日常生活，计算机是离我们很遥远的东西，我认为这辈子也不可能买的起，就是买的起我也没想过要那玩艺，呵呵。
