本文還拓展了實驗條件，通過調整沙粒粒徑配比和空氣濕度，完成了對比性實驗，並進一步探討了粒徑和濕度對沙粒起動的影響，提出了在沙漠工程中控制風沙流形成和沙粒輸運的思路和方法。 -
The diameter is 11. 5 centimetres, whole wooden tire, red treasure sand bottom, adopt gold and silver to be flat to take off skill and technique, is it make various kinds of flowers line kinds to carve gold and silver thin slice, paste in painting foetus smooth of polishing with paint, after being dry, overall xiu several of celluloid paint is it show the honeysuckle line to grind and then, feel abundant, pattern and paint bottom reach same pingdu, push away light become a exquisite one flat to take off the lacquer ware in addition
直徑11 . 5厘米，整木車胎，赤寶沙底，採用金銀平脫技法，將金銀薄片刻製成各種花卉紋樣，用漆粘貼在打磨光滑的漆胎上，待乾燥后，全面髹透明漆數層再經研磨顯出金銀花紋，質感豐富，花紋與漆底達到同樣平度，再加推光則成為精美的平脫漆器。 -
Moreover, this article also discussed how the variation of relative density and average grain diameter influenced the shear stress of sand and gravel layer
另外，順便探討了相對密度、平均粒徑對砂礫石層剪應力的敏感度。 -
Through choosing different diameter of sand granule, using fecl3 and pac as the coagulants, doing paralleled test through standard filtration column compared with referenced filtration columns ( the coarser and the finer sand granule used as filtration media separately ), the thesis investigates the correlation between the filtration behavior and the depth of the deep bed l, the diameter of the sand granule d
本文採用不同粒徑的石英砂濾料，以fecl _ 3 、 pac作為混凝劑，通過進行標準濾池與參照濾池（分別裝填細濾料、粗濾料）的平行對比試驗，研究濾料粒徑改變后，濾池過濾特性與濾池深度l 、濾料粒徑d的相關關系。 -
To solve the problem of sand loss and harden, it is suggested that the diameter of media and the intension of back wash should be enlarged properly, and the time of back wash should be prolonged
但為解決濾料黑化以後在反沖洗中出現跑砂及濾料結塊的現象，建議水廠適當加大濾料粒徑和反沖洗強度，延長反沖洗時間。 -
In designing the deep bed, the empirical formula l / de = 800 is used as the basis. however, it has been proved that the formula cannot precisely describe the functional relationship and the correlation degree between the nitration behavior of the deep bed filtration process, the depth of the deep bed and the diameter of the sand granule, and it is restricted greatly in the practical application of finding a suitable depth of the deep bed
目前，濾池的設計通常採用經驗公式i d _ e = 800作為設計濾池厚度的依據，但實踐證明此經驗公式還不能準確地反應濾池過濾特性與濾池深度l 、濾料粒徑d的相關關系及相關程度，在實際應用中受到很大限制。 -
In the comprehensive fuzzy evaluation model of soil liquefaction, the following factors, such as earthquake intensity, spt counts, groundwater level and mean diameter of sand soil particle which affect the liquefaction of sand soil were considered, and the sketch map of trapezoid subordinate function was adopted and the subordinate function expression of each factor was given
在提出的砂土液化模糊綜合評判模型中，通過綜合地震烈度、標貫擊數、地下水位和平均粒徑等影響砂土地震液化的因素，採用梯形隸屬函數並分別給出各因素隸屬函數的表達式。 -
