Sediment from river is not the main source of the Rushan Bay now any more ,which leads to the change of balance of sedimentation power. Sediment will transport because of the drive of hydrodynamic elements in macroscopic view .Direction of suspended load is basicly the same as tidal current .Flood tide makes suspended load transport to tip of the inner Bay and to the Mouth in exterior Bay .The direction of longside sediment transport in two sides of the Mouth mainly focus in the Mouth .Because the coastline along the exterior Bay is very meandering and it belongs to the type of bedrock ,besides some sediment going into the inner Bay ,so actual net sediment discharge rate is less than calculation .It develops an ebb delta out of the Mouth and forms tidal sand ridge ,tidal washing canal ,barrier bar and marine physiognomy ;The result of model simulation disclosures that differences of sediment erosion and siltation between single tidal action and wave-current action are very big .From the analysis of sediment composition、sediment sources and stability of beach and ridge ,this article gets the conclusion that the channel has the possibility to silt ,though the course maybe very slow.
通过分析研究文章得出如下结论:沉积物平面分布与水动力的时空变化存在很好的相关性;口门外发育落潮流三角洲,形成潮流沙脊、潮流冲刷槽、浅滩、拦门沙等水下动力地貌;乳山湾河流来沙已不是湾内泥沙主要来源导致沉积水动力平衡发生改变,宏观上表现在泥沙受水动力驱动发生不断运移;悬沙运移方向与涨潮流方向基本一致,湾内涨潮流带来的悬移质泥沙向湾顶运移,湾外悬移质泥沙主要向口门方向运移;湾口两侧岸段沿岸输沙方向均指向口门方向,由于乳山湾外海岸线曲折,两侧岸段以基岩为主,加之部分泥沙进入湾内,实际净输沙量小于计算值;数值模拟发现潮流单独作用与波流共同作用下泥沙蚀淤模拟差别较大;从沉积物组成、泥沙来源及滩槽稳定性三个方面分析,文章认为研究区存在航道淤积的可能性,但过程相对较慢。

On average, the SSC in winter is 2 times than that in summer; and the SSC in spring tide is 2.96 times than that in neap tide.(2) The correlation coefficient of the daily tidal range and SSC at a tide circle is 0.86, and it goes up to 0.96 and 0.93 with one day and two days lag of SSC. This reflects that there has a hysteresis of one or two days of SSC to the tidal range.
三年平均而言,冬季悬沙浓度为夏季的2.0倍,大潮悬沙浓度为小潮的2.8倍;(2)平均的大-小潮半月周期变化中日悬沙浓度与同日潮差之间的相关系数为0.86,(显著性水平0.01),与提前1日潮差之间的相关系数为0.99(显著性水平0.01),与提前2日潮差之间的相关系数为0.93(显著性水平0.01),反映潮差变化对悬沙浓度的影响有1-2天的滞后效应;(3)芦潮港月均悬沙浓度与长江大通站的月均流量呈显著负相关,尤以流量滞后19天的相关性最好。

结果表明:1利用植物再生沙障治理流动沙丘可以形成具有多物种、多层片、多层次垂直结构的沙障群落,其水平结构呈网格状沙障结构与障间小群落在空间上镶嵌互补,均衡分布的格局,具有很好的防风固沙和植被恢复效果;2再生沙障建植后第5年开始,沙障群落进入了衰退时期,适时采取科学的经营管理措施对于维持沙障群落的稳定,保障其效益的长期发挥是非常重要的。

The elimination half-life t(subscript β1/2 was 161.10h, 333.21 h and 611.26h, respectively, and the total body clearance was 27.4mL/, 16.8g/ and 18.0g/, respectively. The metabolite ciprofloxacin concentration-time profiles of the plasma, muscle and liver presented similar trend. The multi- peak phenomenon were observed in the plasma, muscle and liver, but the first peak time was 24h, 24h and 12h, respectively. The peak residue of metabolite ciprofloxacin was in liver, muscle and plasma, ordinally. The eliminating rate of ciprofloxacin from muscle and liver was very low.
代谢物环丙沙星在鳗鲡血浆、肌肉和肝脏中药物水平的变化趋势与恩诺沙星基本相似,呈现出多峰现象,但3种组织中环丙沙星出现第一个药峰时间分别为给药后第24小时、24小时和12小时,3种组织中环丙沙星峰值水平肝脏中最高、肌肉中次之、血浆中最低,环丙沙星在肌肉和肝脏中的消除速率比较缓慢。
