By using lamp - house modulating technology and special optical and circuit design , the sediment content is switched to voltage , which is easy to be obtained by advanced calculation technology 采用光源调制技术，结合特殊的光路设计，将含沙量转换为现代实验技术易于处理的电信号。
The result showed that the numerical model could satisfactorily reflect the sediment concentration field , and calculate the back silting intensity on the approach channel in lianyungang harbor 研究结果表明，所介绍的研究方法可以合理地描述含沙量场特性以及计算进港航道回淤量。
The scm data - collection system changes the voltage to numeric signals and then transfer them to the computer , where the data can be analyzed synthetically and synchronously 并针对环形水槽的特殊工作方式，设计数据采集和无线传输接口，送入计算机进行数据后处理及综合分析，实现了含沙量的在线实时量测。
Fossil footprints of arthropods found in western australia that were made in the sandy flats surrounding temporary lakes , indicate that these animals may have accompanied the landward march of plants 被做在含沙舱内甲板围拢临时湖节肢动物的化石脚印发现了在澳大利亚西部,表明,这些动物也许伴随植物landward行军。
The mechanism of silt abrasion is studied . specific contents are summarized as following : 1 . the research results of turbulent flow , sediment - laden , aerated flow and silt abrasion are introduced 对紊动水流、含沙水流、水气两相流及泥沙磨蚀的研究状况进行了综述，提出了本文的研究对象和拟采取的技术路线。
The results show that the correlation dimensions are different in different current conditions . it is indicated that sediment - laden and aerated flows are not completely stochastic , possessing its intrinsic order 结果表明，不同水流状况具有不同的关联维数，含沙掺气水流运动并非完全随机的，而是具有内在有序性。
It is concluded that the phenomena of replacement of spatial and temporal process is typical in the erosion development , the coarsen of riverbeds , the sediment concentration and the change of river regime , etc 分析表明，河流再造床过程在冲刷延展、河床粗化、含沙量及其特征、岸滩侵蚀以及河型变化等方面具有较典型的时空演替现象。
With all these ways , the sediment transportation and concentration of the yangtze river will be half of nowadays for a long time and close to the situation of the tang and song dynasty 治水必治沙，通过“蓄水减沙，借水攻沙”的工程措施，和坚持不懈的水土保持， “标本兼治” ，可使长江输沙量、含沙量长期减少1 / 2 ，恢复到唐宋时代水平。
When the " turbid wind " with almost a saturated sand concentration changes to a refreshing breeze after getting rid of the sand dust around the protective net , it exhibits an even more powerful wind abrasion when blowing across the cliff region 当含沙量几乎饱和的"浑浊之风"在防护网前后卸下沙尘变成清风，在吹过崖区时便显出更强的风蚀作用。
5 . based on the forecasting flow from the real - time forecasting model mentioned above , this thesis tentatively set up the coupling model of rainfall and suspended sediment to serve the water quality control and water supply 通过对流域侵蚀产沙输沙影响因素的分析，在预报流量的基础上，尝试性地建立降雨含沙量过程的耦合模型，以保证供水水质。
