low-tr
解釋
耐低熱-
As for a space - based cloud radar, the change of the radar reflectivity n and the change of attenuation rate along with the cloud liquid water content have been compared between 37 ghz and 94ghz. the transmittance t of single level cloud for different heights and liquid water content has also been calculated at 2 frequencies. by defining a = n tr, which combines both effects of radar reflectivity and transmittance, we have examined the values of a at 37ghz and 94ghz for high, middle and low cloud liquid water contents
對空間測雲雷達，討論了37ghz和94ghz這兩個頻率的雷達反射率和衰減系數隨雲液水含量的變化；計算了不同高度的單層雲在不同頻率，不同含水量情況下的雲層透過率_ ；定義a = _來綜合考慮雷達反射率和透過率對空間測雲雷達回波的影響，分析比較了雲含水量高、中、低時37ghz和94ghz的a值大小。 -
In ported trials, wu gave the minimum tr of all plants, and its diurnal maximum tr persisted stability the most within the range of soil moisture 20. 4 % - 6. 4 %. ; nx lowered its tr and shrank its high - low lines after had experienced irregular wet - drought hardening period during culturing ; kerqin performed a plasticity as compared to field ; c. lanata also stood the most stability but on the basis of middle - high maximum tr level ; tr by caragana korshinski was high when soil water was abundant, but was lowest for lack of water ( 6. 4 % )
盆栽試驗表明，華北駝絨藜蒸騰最弱，且在土壤含水量20 . 4 6 . 4的范圍內最高蒸騰速率穩定性最強；經脅迫鍛煉寧夏駝絨藜蒸騰降低，變幅減小；科爾沁駝絨藜與大田相比蒸騰可塑性較強；土壤水分變化中，北美駝絨藜蒸騰在中高水平上維持穩定的能力最強；水分良好時檸條蒸騰很強，水分脅迫中蒸騰極大降低。 -
Comparing with full light treatment ( control ), tr, gs, wue and light saturation point were significantly decreased, ci was increased by shading. so far as curve of light response, seedlings of 2 tree species represented higher photosynthetic capability under shading treatments in the ranges of low light
和對照的全光照處理相比，遮蔭處理顯著地降低了多脈青岡和金葉含笑的蒸騰速率、氣孔導度、水分利用率和光飽和點，細胞間隙co _ 2濃度在遮蔭條件下顯著上升。 -
