But the CRI and CSR index of coke, used at present, is measured under the atmosphere of no alkali. In the different conditions, alkaline or not, the results of the selective reaction of coke microstructure are different,especially sometimes just opposit...

有碱或无碱存在，对焦炭显微结构的选择性反应序列有时是相反的，并发现∑ISO具有比各向异性结构更强的高温抗碱侵蚀的能力，而前者主要来自气煤类煤，后者主要来自强粘结性煤，因此认为，为了增加焦炭中∑ISO的含量，适当降低对M40(M25)、M10的要求，以达到多用气煤类煤，并改善焦炭的实际质量是可行的。

Local defects in bone as a result of trauma, neoplasm, infection, or congenital diseases are usually filled in and repaired with autografts The fresh autografts are considered to have the highest osteogenous capacity and no immune reaction.

In this study, the ovarial cancer stem cells were successfully obtained through the suspension culture of the ovarian cancer 0VCAR3 cell line in serum-free media. The stem cells formed spherical colonies, called "ovarispheres", and showed anchorage-independent ability. Furthermore, the bionomics and morphology of the stem cells were observed, and the expression difference of the tumor stem cells marker-ABCG2 between ovarispheres and anchorage-dependent cells was identified by using RT-PCR and Immunocytochemistry methods.

The presence of Gas6 in serum-free medium increased phagocytic ability of Sertoli cells by 5 times.

在无血清培养条件下，Gas6可以使原代Sertoli细胞吞噬能力升高5倍。

The results of research showed that compound ferrous flocculant has simple preparation and not any second pollution matter is produced to the environment, it has big and stout floes formation and fast speed sedimentation while dealing with waste water, it is positively charged according to the electrophoresis, it belongs to cationic flocculant, can gives better coagulation results in turbidity removal, color removal, the maximum removal rate of turbidity and color are 95.4% and more than 81.7%, respectively. There are interactions between polysilicic acid and hydrolyzed ferrous species, the compound ferrous with appropriate Si/Fe not only but also can lower the water treatment cost. The compound ferrous removes colloid particles in water by charge oxidation-reduction, neutralization and furl mechanism.

研究结果表明：复合亚铁制备工艺简便，无二次污染；处理水样时产生的矾花大，密实、沉降速度快；复合亚铁带电性为正，为阳离子型絮凝剂；复合亚铁具有较好的除浊、脱色能力，除浊率及脱色率最高分别可达95.4％及81.7％；在复合亚铁中，聚硅酸与亚铁的水解产物间存在着相互作用，合适的硅铁摩尔比有利于提高混凝效果，而且还可以降低投药成本；复合亚铁是通过氧化还原、吸附电中和及卷扫三种作用机理起混凝作用的。

Expression rate induced by thrombin was 50.88% and PAC?1 re?expression was 54.55%. It is concluded that the ability of recovered lyophilized platelets added with reversible activation?inhibitors, DMSO and trehalose to aggregate and coagulate has showed no significant difference as compared with FPRP. The reversible activation?inhibitors can decrease CD62p expression of lyophilized platelets, and may enhance their survival ability and prolongate survival time. Therefore the efficiency of lyophilizing platelets can be improved based on this freeze?drying procedure.

添加血小板可逆性激活抑制剂，海藻糖和DMSO后的冻干血小板，其聚集活性和促凝血功能与新鲜血小板无明显差异，血小板可逆性激活抑制剂降低了冻干血小板的CD62p表达，增强了冻干血小板的生存能力，因而延长了其生存时间，因此可以该冻干方法为基础进一步提高冻干保存血小板的效率。

Meilan also is attempting to find ways to produce trees that are reproductively sterile so they are unable to transfer introduced traits to wild trees.

米兰同时也在试图寻找方法培育无繁殖能力的树以阻止它们将引入的特性传给野生树木。

Results The PGE2 levels in the portal vein increased, while the PGE2 levels in peripheral blood had no changes significantly, the PGE2 levels in the tissues of the intestinal mucosa, placenta, amnion and amniotic cells were increased significantly; Ricinoleic acid stimulated the synthesis of PGE2 in the above tissues invitro, which had the positive correlations with the dose of ricinoleic acid and its lasting time.

结果 实验组大鼠门静脉PGE2水平升高，外周血PGE2水平无变化；实验组大鼠肠粘膜、胎盘、羊膜组织和羊膜细胞PGE2合成明显升高；蓖麻酸刺激肠粘膜、胎盘、羊膜等组织和细胞PGE2合成，其刺激合成能力与蓖麻酸浓度及其作用时间呈正相关。
