In order to extend use of calcium carbonate, the samples were modified by hydrazine hydrate, triethanolamine and sodium stearate. Hydrazine hydrate was 0.08%～0.24% of calcium oxide, triethanolamine was 0.1%～0.3% of calcium oxide, sodium stearate was 5% of calcium carbonate,modification time was 40 minute. Calcium carbonate has better active exponent and white degree.

为进一步扩大纳米碳酸钙的应用范围，对纳米碳酸钙进行了增白活化的改性，改性剂水合肼、三乙醇胺的用量分别取CaO质量的0.08%～0.24%、0.1%～0.3%，硬脂酸钠的用量取CaCO3质量的5%，改性时间为40min，在此条件下可以制得高白度、高活性的碳酸钙样品。

As one of the most important osmoregulation actor, firstly,Proline plays a keyrole in the osmotic potential adjustment in plant cells. Secondly, Proline can preventNaCl from damaging the structure of biomacromolecule in cells. Thirdly, the highdissolubility and non-rejection capability of Proline can enlarge the solution volumnof the cell, so the concentration of salt will be diminished in cytoplasm and the saltstress will be relieved. Forthly, the accumulation of Proline could prevent thedehydrolysis from sap cavity in cytoplasm. Fifthly, the synthesis of plant chlorophyllwill be diminished under the salt stress, but the Proline can provide request ofchlorophyll synthesis.

脯氨酸作为渗透调节剂对植物体细胞渗透势的变化起重要作用：一，在盐胁迫下，脯氨酸在植物体内是一种重要的渗透调节剂，它是一些高等植物和绿藻抗盐和抗旱的主要渗透剂之一；二，脯氨酸可以保护细胞中的生物大分子的结构，使之不被NaCl破坏，并能维持其完整的水合范围；三，脯氨酸的高度溶解性以及其对植物各种酶活性不抑制性，可以扩大细胞的溶解容积，从而降低细胞质液中盐的浓度，减轻盐的胁迫作用；四，细胞质中积累的大量脯氨酸可以防止液泡对细胞质的脱水作用；五，在盐胁迫下，植物叶绿素的合成受到抑制，叶绿素的合成需要脯氨酸。
