| 1. | Controlling the cp species , content , polymer concentration and solvent scaffolds of different pore structure and degradation rate were achieved
复合后材料的力学性能较纯plla支架有所提高，并表现出较好的生物活性。 |
| 2. | Furthermore , the degradation rate of the surgical suture line of chitosan must match up to the cicatrization speed of wound
认为在制备手术缝合线之前有必要对壳聚糖进行预处理，此外缝合线降解的速度应与伤口愈合的速度相互匹配。 |
| 3. | The conclusion in that the degradation rate ofter adding rice hull in the polyurethane foam is higher obviously than that which no addition was made
研究了制备条件，考察了自然条件下的降解情况，可知添加稻壳的聚氨酯泡沫塑料降解率明显高于未添加稻壳的聚氨酯泡沫塑料。 |
| 4. | Immobilized technique ( mainly micro - immobilization ) , is used widely and has great contributions to wastewater treatment , due to its characteristics of high degradation rate and strong adversity resisting property
摘要固定化（主要为固定化细胞）技术，由于降解效率高，抗逆性强等优点，在废水处理中应用广泛。 |
| 5. | In the process of screening high efficient degradation bacteria for crude oil , it was found that the determination results of the degradation rates by uv spectrophotometry and weighing method varied from each other remarkably
摘要在筛选原油降解菌进行废油降解实验时，发现相同批次的发酵液用紫外分光光度法、称重法测定原油降解菌对原油的降解率时，结果相差很大。 |
| 6. | The degradation rate of map was 79 . 95 % in 5 days when the water content in soils was 150 % ( paddy soil ) in laboratory test . the test also showed that degradation rate in paddy soil was higher than that in upland soil
在模拟水田和旱田试验中，加菌5天后水田土壤中甲胺磷的降解率为79 . 95 ，同时发现菌株在水田中的降解效果要好于旱田中的降解效果，含水量高有利于土壤中农药的微生物降解。 |
| 7. | But plla is hydrophobic and not very good for cells seeding . the other disadvantage is that the degradation products reduce the local ph value , which , in turn , may accelerate the plla degradation rates and induce an inflammatory reaction and poor mechanical properties
但是聚乳酸不具备良好的细胞亲和性能，并且聚乳酸在体内降解速率过快，从而导致力学性能变差， ph值降低，过度酸性环境引发无菌性炎症。 |
| 8. | However , transcription rates that represent mrna synthesis may be more relevant in these analyses . because transcription rates are not equivalent to transcript amounts unless the mrna degradation rates as well as other factors that affect transcript amount are identical across different genes , the use of transcription rates in bioinformatics analysis may lead to a better description of the relationships among genes and better identification of genomic signals
转录产物量则与转录调节和后转录调节都有关系。除非对于不同的基因， mrna降解率以及其他影响转录产物量的因子都一致，否则，转录率不对等于转录产物量。所以，在生物信息学中运用转录率可以更好地描述基因之间的关系，更好地识别基因组信号。 |
| 9. | The influences of initiative concentration of rhodamine b , and the acidity of solution on the degradation rate of the tio2 films were discussed in the part of photodegradation of dye rhodamine b . the results indicated that the dye had the best photodegradation efficiency when the concentration of rhodamine b was 10mg / l and the acidity of solution was 3
研究了染料罗丹明b的初始浓度、溶液的酸度等因素对tio _ 2薄膜降解率的影响。结果表明，在本实验条件下，当罗丹明b溶液的浓度为10mg l ， ph = 3时，染料具有最佳的降解效果。 |
