狗年,渐行渐远,悄无声息地离我们而去了。对于狗年“撞狗”运的驾驶人,感触可是酸甜苦辣什么都有,从车狗相撞不属交通事故到属于交通事故,是最分明的分水岭。 相似文献

Carbonyl sulfide (COS) and dimethyl sulfide (DMS) fluxes from an urban Cynodon dactylon lawn and adjacent bare soil were
measured during April–July 2005 in Guangzhou, China. Both the lawn and bare soil acted as sinks for COS and sources for DMS.
The mean fluxes of COS and DMS in the lawn (–19.27 and 18.16 pmol/(m2 sec), respectively) were significantly higher than those
in the bare soil (–9.89 and 9.35 pmol/(m2 sec), respectively). Fluxes of COS and DMS in mowed lawn were also higher than those
in bare soils. Both COS and DMS fluxes showed diurnal variation with detectable but much lower values in the nighttime than in the
daytime. COS fluxes were related significantly to temperature and the optimal temperature for COS uptake was 29°C. While positive
linear correlations were found between DMS fluxes and temperature. COS fluxes increased linearly with ambient COS mixing ratios,
and had a compensation point of 336 ppt. 相似文献

谈起狗对我们环境的影响,似乎有好也有坏.至于不好的影响,却远非一两句话能够说清.或更确切地说,是因为养狗环境意识、尤其是公共环境意识的缺失,导致狗对我们的生活环境产生了危害--这一下,狗就不用喊冤了. 相似文献

狗主人可能认为,利用可生物降解的袋子收集狗粪便,是在尽自己的责任。但是狗狗的粪便被扔进垃圾桶,进行掩埋后,会释放出甲烷,这是引发温室效应的一种重要气体。为此,美国的一家狗狗公园自有解决办法:他们增加了一个沼气池,用狗狗的粪便制作沼气,为路灯、餐车和炸爆米花的仪器供能。 相似文献
