磷酸钙

The Weng'an biota is different from others in that they are phosphatized and soft-bodied fossils.

有别於大多数化石纪录，瓮安生物群化石的主要成份为磷酸钙，而且大都是由软组织所形成的化石。

AIM: To investigate the effect of chitosan on the physical characteristics, ultramicrostructure and biocompatibility of a selfmade calcium phosphate cement.

目的：了解壳聚糖对自制磷酸钙骨水泥物理性能、超微结构及生物相容性的影响。

The tailorable biodegradation of calcium phosphates composite powders can be effectively improved with the composite powders containing nanostructured clusters, in which the different phases exist in uniformly.

按生物环境下磷酸钙实际降解过程的要求，不同晶相的晶粒应形成一个纳米结构化的团簇（即在几百纳米范围内各相均匀分布的纳米晶粒团聚体），这样才能有效地发挥出复相调节生物降解速率的效能。

The result showed that the biodegradation rate of calcium phosphates powders decrease in the order: ACP＞α-TCP≈α-TCP/HA＞HA, ACP＞α/β-TCP＞α-TCP＞β-TCP, This indicates that the biodgradation rates of calcium phosphates prepared in this thesis can be tailorable.

实验结果表明：这些粉末的生物体外降解速率由大到小的顺序为：ACP＞α-TCP≈α-TCP／HA（1：1）＞HA，ACP＞α／β-TCP（1：1）＞α-TCP＞β-TCP；纳米结构化复相磷酸钙现示出降解速率可调性和独特性，如α／β-TCP（1：1）的生物体外降解速率大于α-TCP单相。

In the past, researches focused only on sole function of bacteria such as tricalcium phosphate or ferric phosphate solubilization. In order to efficiently develop superior phosphate solubilizing microorganisms which are useful on various crops, a team includes Professors C.C. Young, C.C. Tang, S.H. Su, H.J. Chen and C.T. Lo in National Chung Hsing University and National Formosa University was established. Microbial consortiums include phosphate solubilizing bacteria, phosphate solubilizing actinomycetes, phosphate solubilizing yeast, and phosphate solubilizing fungi will be designed in the present study and their capabilities to promote crop growth will be demonstrated. The suitable phosphate solubilizing bacterial formula will also be designed. Consideration for the specificity and adaptation of phosphate solubilizing microorganisms to their host crops, the designed biofertilizers will be used as inoculants to increase the yields of various crops meanwhile reduce the overdose usage of chemical fertilizers.

过去研究溶磷菌主要是在各别溶磷之功能上之研发，如溶磷酸钙及溶磷铁，本计画为缩短不同菌种筛选在不同作物之效应评估工作，以组成一研究团队进行不同类型菌种之应用评估，成员涵盖二个大学的研究团队，包括杨秋忠、谭镇中、苏孝华及罗朝村等教授，分别研究细菌、放线菌、酵母菌及木霉真菌，另在菌剂生产配方由陈鸿基教授研究，以提高多元化应用土壤磷素之有效利用，并达到不同作物之应用效应评估，期以探讨开发不同作物专用之微生物肥料之可行性及问题，以减少化学磷肥之施用，降低土壤劣化提高农民所得之目的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
