We hope that our study will provide us with more comprehensive knowledge of the mechanisms of immune regulation and the roles that dc and complement play in innate and acquired immunity, as well as to lay a foundation for further exploration of the roles dc play in antigen - specific immune responses and immune tolerance from a new perspective. part i expression of complement receptors and complement - associated molecules on dendritic cells derived from distinct - origin at different stages of development two subsets of dendritic cells were generated from precursor cells isolated by means of magnetic cell separation system
曰補體受體及其相關分子在modc上的表達不同分化階段的單核細胞衍生性dc （ monocytes一deriveddc ， modc ）的誘導:將新鮮分離的單核細胞mo ，在含有gm一csf和工l一4培養體系中誘導5一7d ，即分化為未成熟modc ;對培養至sd的未成熟modc ，用tnfa刺激zd ，即分化為成熟modc ;此時再用lps刺激24h ，即為活化的modc 。 -
Shanghai xinli battery manufacture co., ltd. to establish in 1994 lately, the precursor is shanghai xinli battery factory lately, the company takes making the alkaline battery alkaline as to predominate the product, various specification, species is basic to cover all serieses of the dry battery, and accept various combination battery of the not standard type of design, to satisfy customer " s demand. xinli battery company lately to have already passed iso - 14000 environment system attestations of iso - 9001 : 2000 international quantity system attestation, the product quantity passes the battery examination center examination of the national light industry bureau and the sgs measurement of the eu ros serieses, the product is qualified. company annually with pass to increase continuously, the extension exports outward and the superior economic specific value service of the underneath brand peony, hongdan, fengdian. etc

Lifepo4 / c composite sample synthesized using coal tar bitumen and carbon both as the carbon precursor under 300 / 3 h + 650 / 6 h also gives a good discharge curves, the discharge specific capacity reached 104. 0 mah / g 、 100. 2 mah / g under the measuring current of 183 ma / g 、 366 ma / g respectively, and it keeps the good cycle performance in nearly 140 cycles. few reports were related to the lifepo4 / c composite synthesized using low cost bitumen as the carbon precursor
採用煤焦油瀝青和乙炔黑同時作為碳前驅體時，在300 / 3h + 650 / 6h的焙燒制度下得到的試樣，在183 、 366ma / g的大電流密度下仍有104 . 0mah / g 、 100 . 2mah / g左右的放電容量，在140次循環內均表現出了很好的循環性能。 -
At the beginning of the reduction, the spherical ni powders precipitated at the tip of the precursor where specific surface energy is higher, then more and more ni powders appeared at the edges and the surface of the precursor ; finally the spherical ultrafine ni powders take the place of the whole precursor
在還原過程中，超細鎳粉首先從凍干前驅體的尖端等比表面能較大的地方析出;隨后前驅體的棱和表面逐漸析出大量的超細鎳粉;最後鎳粉顆粒替代整個前驅體，得到球狀超細鎳粉。 -
Spinel limn2o4 begin to form at 350 with the sintering time of 4 hours because there are one li + and two mn2 + in one precursor molecule. when the sintering temperature is larger than 750, a specific sintering route is designed to avoid the formation of li2mno3 impurities
前驅體的焙燒溫度和焙燒時間對limn _ 2o _ 4樣品的晶相結構有很大的影響，焙燒溫度高於750時，應採用分段焙燒工藝以防止局部高溫形成li _ 2mno _ 3雜質。 -
It has discovered for the first time that the precursor b - ni1 - xcox ( oh ) 2, with pluffy and dendritic morphology, high specific surface area and low tap density, is the best starting material to produce lini1 - xcoxo2 materials, but not the presently thought that high density and spherical particle of ni ( oh ) 2 is fitting for the preparation of ni - cathode materials. using our own precursor can greatly reduce the degree of cation mixing ; improve the electrochemical properties of the aimed materials
發現表面蓬鬆、比表面積高和密度低、呈枝晶狀排列的- ni _ （ 1 - x ） co _ x （ oh ） _ 2前驅體具有較高的化學活性，制得的目標材料可有效抑制陽離子混排產物的生成，而非目前廣泛認為的高密度球形ni （ oh ） _ 2適合作鎳系正極材料的前驅體。
