查询词典 biotic potential

Each unitis of different biotic characters and displays different features of seawater composition during the time. 2 The black unit including a biotic extinction was caused by oceanic anoxic event. Crisis that deepwater keeled foraminifera encountered represents a ferocious anoxia in deep marine environment . Biotic recovery in gray unit reflects gradually improved marine circumstance. What the biotic extinction at the C/T boundary in black unit reflects an environmental mutation, whereas the gradual biotic change characterize the recovery of marine dissolved oxygen environment in a stepwise process. The red unit is the result of oxic deposition and characterized by extremely abundance of foraminiferal faunas, which reflects a high-oxidized marine circumstance. 3 As the most ordinary biotic index in paleoceanography researches, foraminifera represent anexcellent environmental indicator in this paper.

三套岩层表现出不同的生物特征，并指示出当时海水的不同性质。2黑层段是大洋缺氧造成的结果，生物大量灭绝，深层水具旋脊有孔虫的所遭受的危机反映出当时海洋深层水体严重缺氧的特征；灰层段中生物的恢复反映出海洋环境自缺氧事件之后的逐步改善过程，与黑层段反映的C/T 界线处生物绝灭反映的环境突变不同，灰层段生物特征的渐变指示出当时海洋溶解氧环境的恢复也是一个逐步的过程；红层段属于富氧沉积的产物，特征是有孔虫生物的极度繁盛，反映的是一种高氧化性的海洋环境。3有孔虫作为古海洋研究中最常用的生物指标，在本文研究中显示了良好的环境指示性。

However, the prediction has a limitation of underestimation and overestimation at low and high temperature or moisture conditions respectively. In order to acquire accurate estimation of soil respiration, main suggestions for further study are to: combine measurement of soil respiration by chamber with carbon flux of ecosystem by eddy covariance, measure synchronously the biotic and abiotic factors, especially pay more attention to the role of modification of biotic factors on the performance of abiotic controllers, make more measurement in typical plant phenology phase and different weather conditions, and strengthen experimental manipulation and modeling.

但是在土壤温度及湿度过高或过低的情况下会出现较大的误差，为了尽量减少土壤呼吸的误差，给出了如下建议：①加强土壤呼吸和生态系统自动碳通量的结合研究；②加强对不同生物和非生物生态环境因子的同步测定，特别重视生物因子对非生物因子的调节和影响；③加强典型物候期和不同季节典型天气土壤呼吸的测定；④加强模拟试验研究和模式研究。

In order to prove the importance of three-body interaction, accurate ArH〓 potential surface and accurate ArAr potential surface are added to construct a two-body potential surface. We found that this potential surface is corresponding with a deep potential well and a tight structure, which is far from the real structure of Ar〓H〓. Obviously, this two-body additive potential surface is not suit in this system.

为了证明三体作用在体系中的重要性，我们用精确的ArH〓的势能面与精确的ArAr的势能面构造了一个两体加和的势能面，发现两体加和的势能面表现的是一个深势阱的紧凑结构，与Ar〓H〓的结构相去甚远，因此可以确认，两体加和在此系统中是不适用的。

The reduction of trihalomethane formation potential was discussed, which indicated that ozonation has a good removal for chlorofom and bromodichloromethane formation potential, but for dibromochloromethane formation potential the removal efficiency was undesirable and there was almost no removal for bromoform forming potential, Furthermore, when there was enough bromide in water, ozonation would have a promotion effect for bromoform formation potential.

通过研究臭氧对三卤甲烷生成潜能的去除规律发现，臭氧对三氯甲烷和二氯一溴甲烷生成潜能都有很好的去除，对一氯二溴甲烷生成潜能的去除效果较差，对溴仿生成潜能基本没有去除。当水中溴化物含量较高时臭氧对溴仿的生成反而具有促进作用。
