At present, Beijing Huayi puts its main strength on China City Blue Page, a Beijing-based project aiming at whole China. In addition, we have successfully applied patent for China City Blue Page Public Information Free Inquiry Machine and registered China City Blue Page brand. Now Beijing Huayi is a forerunner in IT industry in China.

Compared with the blank controls, aldrin at concentrations higher than 80 μg/L decreased life expectancy at birth and net reproduction rate of maternal generation of the cladoceran, and that at concentrations higher than 160 μg/L shortened generation time and decreased intrinsic rate of population growth.

与空白对照组相比，浓度高于80μg/L的艾氏剂使多刺裸腹溞母代的生命期望和净生殖率显著降低；浓度高于160μg/L的艾氏剂使母代的世代时间显著缩短，种群内禀增长率显著降低。

This experiment indicates that Ig-Guard can effectively enhance the shrimps'activity of enzyme about non-special immunity, and it can also promote shrimps'resistance to WSSV. The third study is the effect of Ig-Guard on impacting the resistance to WSSV of Procambarus clarkia.

WSSV卵黄抗体保护克氏原螯虾防御白斑综合征病毒的研究：在基础饲料中分别添加3个水平(1%、0.5%、0.1%)的Ig-Guard制成3种试验饲料，同时以基础饲料为空白对照。

The results show that the mineral admixtures can reduce C3A quantity in the cement material, and the pozzolanic reaction can consume lots of hydration product-Ca2, Which makes specimens close-grained, has obvious prevention function towards the sulfate corrosion. The anti-sulfate corrosion effects of various mineral admixtures from finer to poorer in turn are as follows: 30% fly ash, 30% fly ash + 30% slag, 60% slag, 30% steel slag + 30% slag, 30% steel slag, 30% slag, the blank type.

研究结果表明：加入矿物掺合料降低了试件的胶凝材料中的C3A含量，其火山灰反应消耗了大量的水化产物Ca2，且提高了试件的密实度，对硫酸盐侵蚀具有明显的预防缓解作用；各矿物掺合料的抗硫酸盐侵蚀效果由优到劣依次为：30%粉煤灰，30%粉煤灰＋30%矿粉，60%矿粉，30%钢渣＋30%矿粉，30%钢渣＞30%矿粉，空白样。

This technology is a blank one in the field of coal abroad and home, and in other industries of China the use of similar technology also begins just now.

该技术在国内外煤炭领域属于空白，在我国其他行业类似技术应用刚刚起步。

The result showed10%Caowei weeded widely,had specially good effect on sedge family and broadleaf weeds and cockspur grass,the total effect of10%Caowei15g /667m 2 was6.8%more than10%Caokexing,22.2%more than10%Yikejing,improved17.9%in output than blank.

结果表明，10%草威杀草谱广，对莎草科和阔叶杂草有特效，对稗草有极强的抑制使用。10%草威15g/667m2总防效比10%草克星提高6.8%，比10%一克净提高22.2%，比空白对照增产17.9%。

They raise new issues, such as the possibility of gap penalties that penalize codon frame shifts.

他们提出新的问题，例如的空白惩罚的可能性处罚密码子框架转移。

The all kinds characterization of the silicone rubber cold shrinkable tubing was investigated in this dissertation.
