To verify the accuracy of CFD simulations, experiments were carried out. The results of simulations with user defined function of the effects of impeller type and stirring rate on the velocity field were in good agreement with the output of particle image velocity.

结果表明，(1)采用Fluent软件并结合用户自定义方程(user defined function， UDF)能够很好地模拟出实际搅拌器内流场分布，模拟结果与采用粒子成像技术(particle image velocity， PIV)的实验测量结果相符；(2)采用氧气传质模型能预测氧气在搅拌器内的动态传质过程，同时氧气浓度与溶解时间的对数关系式能较好描述试验搅拌器内氧气动态传质过程；(3)在相同搅拌速度下，圆盘涡轮式搅拌器产生的湍流动能分布范围要大于桨式搅拌器产生的湍流动能，而且湍流动能分布更均匀，湍流强度更大。

Then they examined PTEN in nonhereditary breast tumors from 297 patients and tumors from 34 women who had inherited the BRCA1 mutation. In most cases, the protein that PTEN produces was undetectable in tumor cells, but clearly present in nearby normal cells.

然后他们检查了297名患非遗传性乳房肿瘤的妇女和34名遗传了BRCA1变异并患肿瘤的妇女，发现在大多数情况下，肿瘤细胞里检测不到由PTEN产生的蛋白质，但在附近正常细胞的周围明显存在由PTEN产生的蛋白质。

Taking root suckers of Hippophae rhamnoides artificial population as the research object, based on the field investigation of produced number of clones, space distribution and growth condition, basic characteristics of ramet and relationship of environmental factors and root suckers were studied systematically in different habitats in Zhifanggou hilly-gully regions.

以沙棘人工种群根蘖萌苗为研究对象，通过对丘陵沟壑区纸坊沟流域不同生境沙棘人工种群根蘖萌苗，产生的无性系个数、空间分布和生长状况的调查，系统研究不同生境条件下沙棘人工种群的根系产生幼苗的基本特征及其与环境因素的关系。

The microstructure and thermal physical properties of the surface reactional layer determine the range of strength improvement.Stress relaxation was benifical for strength,but the oxidation-induced bubbles and crack weaken the specimens.

热处理引起的应力松弛也有利于材料强度的提高，但氧化过程中产生的表面气孔及冷却过程中产生的表面微裂纹会引起材料强度的下降。

Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.

木塑复合材料的老化机理为：光和热引发木塑复合材料中木质组分和塑料组分大分子链断裂，产生的自由基与氧气作用，发生链支化反应生成羰基、氢过氧化物等，发生交联反应生成烷氧基等；水分破坏木-塑界面、水解酯类添加剂、抽提小分子添加剂和降解产物；微生物分解纤维素、半纤维素、木素和酯类添加剂；木塑复合材料中各组分的降解产物相互促进老化，PVC降解产生的HCl溶于水，促进了纤维素和半纤维素的水解。
