percent slope 中文意思是什麼
percent slope
解釋
百分度坡度-
Fifty percent of the land area has a slope greater than 40 degrees and is ecologically suitable for forest cover only.
50地區的坡度大於40度，而從生態學上說只適合於森林覆蓋。 -
Wells are installed at two well depths per well nest, respectively 1m and 0. 7m. samples are analyzed for nitrate nitrogen, ammonium nitrogen, total nitrogen, and total phosphor to compare the effect of vegetation type, different field slope and different season. main research results and conclusion of the study are as follows : 1 ) percent total nitrogen is higher in the deep wells 1m than the wells 0. 7m, by 11. 43 %
以水樣中銨氮、硝氮、總氮、總磷為監測指標，比較了不同深度、不同植被類型、不同季節、不同坡度、不同濃度營養鹽沖擊下，緩沖帶對氮磷等營養鹽的消除效果，試驗結果如下： 1 ）與0 . 7m相比，樣點1m深處，緩沖帶對總氮的去除效率要高些，二者相差11 . 43 ，而緩沖帶對銨氮、總磷、硝氮的去除效果，不同深度，消除率比較接近。 -
3 ) the riparian buffer effectiveness is relate to field slope. 8 % slope buffer is more effective than the 5 % slope buffers at decreasing nitrogen. the slope does not seem to play a important key on phosphor concentration decrease. 4 ) a higher percent nitrogen and phosphor decrease is observed in spring compared to autumn and winter. reasons may be attributed to growth of vegetation
坡度為8時，緩沖帶對銨氮、總氮、硝氮的消解率均高於坡度為4時的消解率，兩種不同立地模式，緩沖帶對氮營養鹽的消解率存在差異；而緩沖帶對磷的消解效率受坡度影響不大，沒有顯著差異，說明不同的立地模式對氮磷營養鹽的影響是不同的。 -
By studying the principal types and character of the rocks and soils in fengjie section, the structure of reservoir bank and its combination types and the developing and distributing status of the reservoir bank ' s deformation and breakage. reservoir bank in fengjie section, which is 10. 352 kilometres long from lijia big valley to laolongdong valley, is systemic classified as 12 engineering and geology subsections. the reservoir bank being composed of rock slope is 2142 kilometres, 20. 7 percent of the whole reservoir bank
通過詳細研究庫區巖土體的基本類型及特徵、庫岸結構及其組合類型和庫岸變形破壞發育分佈狀況，對奉節新城區庫岸10 . 352km段進行了系統的工程地質綜合分段，從李家大溝至老龍洞沖溝劃分了12段，其中巖質岸坡庫岸長度2142m ，占整個庫岸段的20 . 7 ；土質岸坡庫岸總長度8210m ，占整個庫岸段的79 . 3 。 -
The experiment result accord with the theory ' s. when the transmission rate of output mirror equal to 4. 9 percent. the output power is 1w. the slope efficiency is 54. 1 %
我們用透射率t = 4 . 9的鏡片作為輸出鏡，當泵浦功率等於2 . 2w時，最大單頻紅外激光輸出為1w ，斜效率為54 . 1 。
