- It was suggested that Ca deficiency in plants was caused by the low contents of exchangeable Ca and low pH value in soil. 果園土壤交換態鈣含量低及土壤酸性強是引起植株鈣素缺乏的主要原因。
- Aqueous phase is dominant under veryhigher pCh and low pH values. 溶液相只在很高pCl值和低pH值下佔優勢。
- Because the factory is small and its production wastewater is characterized by the high COD, SS, low pH value etc, IC reactor was selected as the anaerobic reactor. 針對該廠規模小,土地資源有限,排放的酒糟廢水COD、SS濃度高,pH值低等特點,選用IC反應器作為本研究厭氧處理設備。
- Low PH value of initial blood gas, early onset of symptoms at birth and total absence of hemidiaphragm were the three most poor prognostic factors (P<0.01). 初動脈血PH值<7.;2,出生后即有呼吸窘迫及半邊橫隔膜全部缺損是影響預后最大的三個因素(P值<0
- A simple spectrophotometric method for determining low pH value was developed based on the absorption decline of brilliant cresol blue in strong acid solution(0<1.0). 利用燦爛甲酚藍在強酸條件下(0<1.;0)吸光度隨溶液中H+濃度的升高而有規律的下降;提出一種快速測定溶液酸度的分光光度法。
- Oenococcus31DH and SD-1were selected as research microbial strains. The effects of SO 2 on malolactic bacteria in ATB culture medium and the conspiracy of SO 2 and alcohol or low pH value were studied. 選擇酒明串珠菌31DH和SD-1作為研究菌株,在ATB培養基中研究了SO2對蘋果酸-乳酸細菌菌株的影響以及SO2與酒精和低pH之間的協同作用。
- So it is concluded that anatase is easier to form at lower pH value, but rutile at higher pH value.Ascent of base strength from increase of pressure can promote the formation of brookite. 因此在低pH值趨向於生成銳鈦礦相,高pH值趨向於生成金紅石相,而壓力增大導致的鹼性增強是促進板鈦礦相形成的主要因素。

- low pH value treatment 低pH值處理
- Effectiveness :Gentle clean,Balanced flesh PH value. 功效:柔和清潔,平衡肌膚PH值。
- The results show that free cement corundum based self-flow castable matrix has good dispersion states when PH value is 10 and 0.04% Na_3(PO_3)_6 is added as dispersant.under the experiment conditions. 結果表明:在本試驗條件下;無水泥的剛玉質自流澆注料基質泥漿較好的分散條件是在PH=10的水溶液中;加入0.;04%25的六偏磷酸鈉做分散劑。
- In the condition of the same pH value and quantity,the sequence of from high to low of CTR value is:PACPc>PAC>PACPa. 在相同pH值及相同用量的條件下,CTR值由高到低的順序為:PACPc>PAC>PACPa。
- The pH of a food also is critical because a low pH favors the growth of yeasts and molds. 食物的ph值也非常重要,因為低ph值有助於酵母和黴菌的生長。
