实验结果表明：木瓜蛋白酶、复合多聚磷酸盐、氯化钙和糖类保湿剂都可增加肉脯的嫩度，但用量应适当，添加量过大，反而使肉脯的感官品质变差；肉脯嫩化的最佳配比为木瓜蛋白酶0.4‰、复合多聚磷酸盐0.4%、氯化钙0.1%、山梨糖醇1.5%。

OrLPT1 ORF encods a polypeptide with 535 amino acid residues (molecular mass of 57.6KDaltons), which shares more than 64% amino acid identity with some other high-affinity Pi transporters of plants. Hydropathy analysis of the deduced polypeptides showed that the OrLPT1 is highly hydrophobic and contains 12 putative membrane-spanning regions.

The results of the CV study showed that the interaction was mainly of an electrostatic one in phosphate buffer solution at pH 4.4,whereas intercalative binding played a dominant role at pH 6.5 and 7.4 solutions.The results of the UV-Vis spectroscopic study further confirmed them.

电化学测量结果表明，在pH4.4的磷酸盐缓冲液中，AE与DNA之间以静电作用为主，而在pH6.5和7.4的磷酸盐缓冲液中，则以嵌入结合为主，紫外-可见吸收光谱也证明了这一结论。

The electrochemical results indicated that the interaction between TH and CT-DNA is in the intercalative mode in the pH 7.2 phosphate buffer solution, but both intercalative and electrostatic modes exist in the pH 6.5 phosphate buffer solution.

电化学测量结果表明，在pH7.2的磷酸盐缓衝溶液中，TH与CT-DNA之间的作用方式以嵌入结合为主，在pH6.5的磷酸盐缓衝溶液中，TH与CT-DNA之间的作用方式既存在嵌入结合也存在静电作用。

Studies show that the average ratio of w/w(P2O5)(1.62) of phosphates in submarine guyots is the same as that of w/w(P2O5)（1.621）of carbonate-fluorapatite, but is obviously different from that of w/w(P2O5)（1.318）of fluorine_carbonate, suggesting that the phosphates from northwestern Pacific are species of carbonate_fluorapatite.Three types of microneedle-microcolumnar, microgranular and microcryptocrystalline carbonate_fluorapatite with different abundances have been found.

海山磷酸盐的平均化学成分w/w(P2O5)（1.62）与碳氟磷灰石的w/w(P2O5)（1.621）几乎一致，而与氟磷灰石的w/w(P2O5)（1.318）相差甚远，表明海山磷酸盐为碳氟磷灰石，其形态主要有针状_柱状微晶碳氟磷灰石、粒状微晶碳氟磷灰石及显微隐晶质碳氟磷灰石3种类型，它们在分布丰度上存在差异。
