The esterifying effects of monascus, daqu and rhizopus strain on single acid (acetic acid, caproic acid, lactic acid, butyric acid) and mixed acid (acetic acid,caproic acid,lactic acid, and butyric acid mixed together according to the ratio of 1∶1∶1∶1) were studied.

对红曲霉、大曲以及根霉菌对单一酸（乙酸、己酸、乳酸、丁酸）和混合酸（四大酸按1∶1∶1∶1混合）的酯化效果进行了研究，结果表明，红曲霉能促进己酸、丁酸及混合酸与乙醇的酯化作用，生成的酯类物质均为己酸乙酯，而且酯化能力极强；大曲能促进己酸、丁酸及混合酸与乙醇的酯化作用，生成的酯类物质均为己酸乙酯，并且能促进乙酸与乙醇的酯化生成乙酸乙酯；根霉能促进己酸和混合酸与乙醇的酯化作用，生成少量的己酸乙酯和乳酸乙酯。

The drug release experiments in vitro indicated that with the increase of PLA molecular weight, the drug release rates decreased. 4ac releasing from 4ac-PLA-NP could be characterized by Weibull's equation. The interaction between 4ac and others compositions was not detected by DSC. The peak position of 4ac in DSC did not changed comparing 4ac with 4ac-PLA-NP lyophilize injection. Thc X-ray result showed that the peak of 4ac-PLA-NP was piled up between 4ac and other compositions.

差示扫描量热分析结果表明药物与各组分之间无明显的相互作用，制成4ac-PLA-NP冻干针剂后，其放热峰主要表现为聚乳酸的放热峰：X-射线衍射结果表明药物与载体间无相互作用，4ac-PLA-NP主要表现为4ac与载体之间的叠加峰；TLC、FT-IR也同样表明药物与载体无相互作用，它们之间是一种物理结合，并未有新物质生成。

Extracts of ROSA RUGOSA with strong whitening effect can reduce the generation of melanin and improve skin quality, to make your skin bright, white, and resilient.

具有超强美白效果的玫瑰花提取物，能够在肌肤基底层减少黑色物质生成，改善肤质，令肌肤亮泽嫩白，富有弹性。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
