Production technique and product standard of feed defluorinated tricalcium phosphate at home and abroad were introduced, and suggestion on the development and extension of feed defluorinated tricalcium phosphate in China was put forward.

论述了国内外饲料脱氟磷酸三钙的生产技术，发展状况，产品质量指标和国内饲料脱氟磷酸三钙的工业化生产技术，并就我国发展和推广饲料脱氟磷酸三钙产品提出建议。

As the reaction time and standing time increase, the percentage of calcium oxalate trihydrate decreases and the percentage of the thermodynamic stable calcium oxalate monohydrate increases.

随着反应时间和陈化时间的增加，三水草酸钙直接转化为稳定态的一水草酸钙，而没有经过亚稳态的二水草酸钙。

Orange is short of calcic disease lamina advocate fade is green near arteries and veins and Xie Yuan, fade green place produces withered spot to fall off after, vimineous top is down withered dead.

当土壤偏酸，或土壤中氮。钾。镁偏多时，都轻易造成土壤中缺钙。所以应适当施用石灰，可中和土壤中酸，提高置换性钙的含量和肥沃度，能减少缺钙症发生。

However, in recent yean, the landscape come to be dried up. Blacken, sanded, which have seriously affected the sight's admiring value. It is Very important to take the landscape measures and control human activity to research the rules and influencing factors of travertine. It will be good to society, economy.

但近年来黄龙钙华出现了干涸、变黑、沙化等现象，严重影响了景观的可观赏性：深入研究该区的钙华演变规律和影响因素，对于采取科学的保护措施，控制人为活动时钙华资源的不利影响将其有重要作用。

Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin, demineralized bone matrix were implanted into the muscle pouch of mice, at different times after implantation, the immunological, histological and alkaline phosphatase assay were conducted. The results revealed that all four kinds of allogeneic implants activated specific cellular and humoral immune responses, most notably in fresh bone group, the AAA, BMG and DBM inhibited the proliferation of the lymphocytes in vitro and BMG had the most powerful inhibiting action, allogeneic AAA, BMG and DBM might induce heterotopic osteogenesis in vivo, however, there were obvious difference in ALP and histomorphometry between allografts and isografts.

在小鼠肌肉内植入同种异体或同系新鲜骨、自消化抗原去除骨、骨基质明胶、脱钙骨基质，术后免疫学、碱性磷酸酶、组织学检查发现：4种同种异体植入物均可引发特异性细胞免疫反应和体液免疫反应，其中以新鲜骨移植引发的免疫反应最为显著；自消化抗原去除骨、骨基质明胶、脱钙骨基质在体外具有抑制淋巴细胞增殖的作用，骨基质明胶对淋巴细胞增殖的抑制作用最显著；同种异体与同系4种植入物在体内成骨活性有显著差异；自消化抗原去除骨、骨基质明胶、脱钙骨基质均有异位诱导成骨活性，其中骨基质明胶骨诱导活性最佳。
