However, the size and amount of microporosity increase with the recycle material proportion, and the microporosity in 100% recycled alloy is much more than that in the virgin alloy.

当返回料比例不超过80％时，返回料的加入对合金的高温持久性能和室温拉伸强度没有明显影响，但室温延伸率有所下降；100％返回料合金的力学性能明显下降，其高温持久寿命和室温延伸率已不能满足技术条件要求。

SBA-15 samples prepared from sodium metasilicate had higher microporosity and thicker pore walls,with reduced self-assembl...

These results suggest that estrogen may play an important role in maintaining the structural integrity of cells. But these experiments have not explained the influence of estrogen on endothelium and myocardium morphologically.

这些结果提示我们雌激素可能在维持细胞结构的完整性中起着重要作用，但是这些实验都没有从形态学上阐明雌激素对血管内皮细胞和心肌细胞的影响。

By retrovirus vector the foreign mdr1 gene could be efficiently transferred into bone marrow mononuclear cells of mouse in vitro, and it was confirmed that mdr1 gene was expressing stably and effectively in cells; in short terms there is no significant influence on the bone marrow MNC by transfection of mdr1 gene,but in the long run(in our study we had surveyed 2 months),there is a decline in the expression of apoptosis factor Bax in the MNC which transfected by mdr1 gene,in favour of the recovery of the receptor mouse;on the other hand it also poses a blance problem between multiplication and apoptosis in the process of receptor hematopoiesis after transplanting HSC which was transfected with mdr1 gene.

通过逆转录病毒载体可在体外将外源性mdr1基因转入小鼠骨髓单个核细胞中，转染的mdr1基因能整合到骨髓单个核细胞基因组中并有功能性表达；mdr1基因转入小鼠骨髓单个核细胞在移植后短期内对受体造血细胞没有显著影响，但从长期看来(本研究观察2个月)转染了mdr1基因的造血干细胞的凋亡因子Bax表达降低，更有利于受体鼠造血的恢复；另一个方面它也同时提出一个问题，即mdr1基因转染造血干细胞在回输受体后造血过程的增殖凋亡平衡。

The organic and normal production system had no significant differences on the yield and quality of muskmelon.

结论］有机和常规2种生产系统对甜瓜的产量和品质的影响没有显著差异。

There were no strong correlations between nectary structures and pollinator behavior, although gelatinous or watery nectar was associated with the foraging preference of pollinators.

它们的蜜腺结构和传粉者行为之间没有明显的相关性，但是胶质或水质的花蜜对传粉者的取食方式有一定影响。

Although China's capital market has not fully open the existence of "firewall" of protection but the financial crisis on China's financial markets the negative impact of capital markets can not be avoided.

尽管中国资本市场并没有完全开放，存在"防火墙"的保护，但是金融危机对中国的金融市场、资本市场的负面影响不可回避。
