Critical C/Fe ratio as a new concept has been put forward in this paper, when the amount of carbon adding into pellet large than critical C/Fe ratio, it will results that the S% of DRI goes beyond the criterion so that EAF refuse to use it, when less than critical C/Fe ratio, it will accelerate reduction and desulphur.

文章根据热态DRI的再氧化机理，提出了一种利用半熔融密封料覆盖反应罐口的防再氧化理论，在还原温度时半熔融密封料熔化成液相，将罐口密封，反应罐冷却时，这层半熔融密封料凝固并和罐壁紧密结合，阻止氧化性气体的侵入，达到防氧化的目的。

Optical imaging characteristics of multi-layer diffractive optical elements were discussed.

IRHV was demonstrated in 153/270(56.7%), CHV was demonstrated in 68/270(25.2%). Conclusions Portal and hepatic vein can be displayed accurately by 3D 64-MSCT angiography , which could measure diameter or other information about the veins at any cross-section. Meanwhile, more anatomic information could be provided for hepatic segments resection and liver transplantation directively. Portal and hepatic vein diseases could be diagnosed by 3D 64-MSCTA accurately and directly also.

肝脏门静脉及肝静脉的多层螺旋CT血管成像能准确、立体地显示大血管的空间位置关系，在不同的切面上准确测量血管的直径或其他的解剖学数据，为临床提供大量有用的解剖学信息，对确定肝脏病灶的叶段切除和肝移植的手术方式具有指导价值，同时还能直观、准确地诊断肝脏门静脉及肝静脉的病变。

Layered sodium disilicate s (Na_2Si_2O_5) have good ion binding capacity, provide appropriate water alkalinity; and may cooperate with other composition in good method, They were considered as excellent non-phosphate detergent builder and have good prospect for substitut.

层状二硅酸钠由于具有优良的阳离子脱除能力、碱性适中、与洗涤剂其它成分配伍性能好被认为是优良的无磷洗涤剂助剂，具有良好的工业前景。

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase（Rf0.57、Rf0.63）(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.

通过对日本凹顶藻以不同溶剂的粗提、乙醇提取物的极性分离、不同极性的薄层层析和多糖的提取，进行抗菌试验的研究，发现95%乙醇和V甲醇：甲苯为3∶1的提取的活性物质具有较强的抗姬松茸的病原细菌活性，乙酸乙酯相对病原细菌的抑菌强于乙醇的粗提物，而水相基本无抑菌效果，乙酸乙酯相的两个带（Rf0.57、Rf0.63）浓度为0.1g/ml具有较强抗姬松茸病原细菌的活性，对假单孢杆菌抑菌圈达到19.3mm，水相层析带的抑菌活性较弱，多糖的粗提物配成0.25g/g的水溶液对姬松茸病原真菌有较好的抑菌效果对黑曲霉、桔青霉和绿色木霉的抑菌圈分别达到10.8 mm、7.9 mm、5.3 mm。

The dult stem cells abilities of differentiation, self-renewing and self-maintenance tended to be limited so that it, which is characterized of short life time, could differentiate by means of mono-direction or double direction. What is the most important is that it can not differentiate all cells from the three embryonic layer.
