查询词典 trophic level

Theoretical calculation shows the anomaly of reservoir tidal gravity is measured at μGal level, while the measured data shows the observation error of such tidal gravity at 10-μGal level. This indicates that the data noise may well disguise real anomalies, and therefore that the lack of measured anomaly data does not necessarily equate to the lack of oil and gas reservoir underneath. The actual observed tidal gravity anomaly can reach tens of μGal. Though it is more than three times the observation error, we can not attribute it to the reservoir-induced tidal gravity anomaly.

理论计算表明，油藏潮汐重力异常在微伽量级，而实际资料表明潮汐重力的观测误差为10 μGal量级，油藏潮汐重力异常可能会被噪声淹没，所以没有观测到潮汐重力异常不等于地下没有油气；实际观测的潮汐重力异常可达数十μGal，即使超过观测误差的3倍，也不能将它直接归因于油藏产生的潮汐重力异常。

Results:Part1: Mean serum EPO concentration of CRF patients showed significant lower than that of control. After transplantation, renal function recovered quickly while Hb level increased steadily in 37 patients with immediate graft function. Their EPO concentration increased significantly and double peaks of EPO level were obtained at day 4 and week 4. 4 cases in IGF suffered from post-transplant erythrocytosis. But their EPO concentration did not reach statistical significance. 5 cases developed delayed graft function, without EPO double peaks and their EPO concentrations showed signiffcant lower than that of IGF.

结果：第一部分：尿毒症病人血清EPO浓度明显低于正常对照值。37例立即肾功能恢复者，SCr迅速下降，Hb上升，其血清EPO浓度在术后第4d形成第一个高峰，与术前和正常对照比较均有显著差异，其后开始下降，在术后4w时再次升高形成第二个高峰。4例IGF患者在术后16w左右发展为PTE，其EPO浓度值略增高，但与IGF组患者EPO水平无统计学差异；5例DGF患者术后无典型的双峰特点，EPO水平明显低于同时期IGF组，直到肾功能恢复后才逐渐升高。
