  8. The methods of paper chromatography - mottle elution cnromometry and enzyme - dns colorimetric were defined. these methods were simple, cheap and accuate. the results showed that the positive correlation was obtained between trehalose concentration and acetic acid or osmotic tolerant

    提出了「紙層析-分離洗脫法」 、 「酶- dns比色法」定量測定海藻糖的方法，該方法簡便、成本低、準確度高。
  9. Development of a tomato juice concentration system by spiral reverse osmotic membrane

    反滲透膜的鐵污染與清洗
  10. Effect of salt treatment on ionic concentration and osmotic potential of cell sap of leaves 2. 1 effect of salt treatment on ion concentration of cell sap of leaves 2. 1. 1 effect of nacl treatment on ion concentration of cell sap of leaves the concentrations of na and cl in the cell sap of leaves increased rapidly with the increase of naci concentration in medium, but the amounts of ci " were lower than those of na +

    1nacl處理對堿蓬幼苗葉片細胞汁液離子濃度的影響堿蓬幼苗葉片細胞汁液的na ~ +和cl ~ -濃度都隨著nacl處理濃度的增大迅速增加，但cl ~ -增加量低於na ~ + 。這些結果說明堿蓬幼苗可積聚na ~ + ，作為滲透調節劑。
