This experiment is for the purpose of unifying the porine ovocyte in vitro mature raise and the ROSI correlation operation, establishes in the ovicell nature the round sperm cell microinjection fertilization technology procedure, the exploration porine round sperm cell micro fertilization possibility, the research affects this kind of special cell microinjection fertilization effect the factor, for further studies the porine ROSI technology to provide the basic data.

本试验旨在结合猪卵母细胞体外成熟培养及ROSI相关操作，建立卵胞质内圆形精细胞显微注射受精技术程序，探索猪圆形精细胞显微受精的可能性，研究影响这种特殊细胞显微注射受精效果的因素，为进一步研究猪ROSI技术提供基础资料。

The theoretical analysis and the experimental results consistently show that, the oxidation of Si〓N〓-bonded SiC refractory adheres to the parabolical type rule of oxidation and the oxidation in the condition of actual BF operation is passive one.

在此基础上，综合SiC砖蚀损过程研究结果，阐述了炉墙传热过程与其蚀损的相互关系，进而探讨了高炉用Si〓N〓结合的SiC砖的适宜条件，提出了控制碱蚀、减轻热震破坏以及改善高炉用SiC质砖衬的使用效果的技术方向和途径。

They vary greatly in composition between species. The hemicelluloses and pectic substances interact with the cellulose microfibrils of the cell wall to give extra strength and at the same time retain some plasticity.

半纤维素和果胶质与细胞壁中的纤维素微纤丝相结合，这样就具有了较大的强度同时还可以保持一定的可塑性。

When protein folding is compromised in the periplasm of E.

当大肠杆菌E.coli周质中蛋白折叠发生阻碍，外膜蛋白OMPs的C端与三聚体DegS蛋白酶的 PDZ区域发生结合，促使ResA裂解。

So it is of much significance to study the mechanisms of ovule development and abortion of Chi- nese pine. By combining two-dimensional gel electro- phoresis (2-DE) and mass spectrometry analysis, the pat- terns of gene expression in a specific tissue at a specific stage can be displayed and characterized.

双向电泳和质谱技术结合研究基因表达的蛋白质组技术正越来越广泛地应用到植物研究中，我们将该技术应用到油松胚珠发育的研究中，比较了两种蛋白质提取的方法，发现蔗糖提取方法比传统的TCA 方法更适合于油松蛋白质的制备。

The microstructure of the sintered bone was observed by scanning electron microscope and mercury porosimeter. Results showed that the sintered bone possess the three dimensional space structure composed of macropores and micropores. The diameter of macropore was 50-400 μm and the diameter of micropore was about 1 μm. Results suggest the sintered bone of β-TCP remains the porous structure of natural cancellous bone which is benefit to growing of new bone.

结果显示β-磷酸三钙煅烧骨具有大孔结构和微孔结构相结合的三维空间结构，大孔孔径为50~400 μm，微孔孔径为1 μm左右，提示β-磷酸三钙煅烧骨保留了天然松质骨的多孔状结构，有利于新生骨组织的长入。

By push-pull perfusion technique and radioenzymatic assay, it was found that after 10 min of acupuncture, pain threshold increased significantly, while the content of NA in the perfusate from the preoptic area was markedly decreased.

b。用推挽灌流技术结合放射酶学法，观察针刺镇痛时视前区NA释放的变化，从递质释放的角度，探讨视前区的NA在针刺镇痛中的作用。结果观察到针刺10min后，动物痛阈明显升高，此时视前区灌流液中的NA含量显著减少。

Dot1 binding to chromatin occurs normally in the absence of H2B-K123 ubiquitylation, suggesting that ubiquitylation does not regulate enzyme recruitment but does regulate the processive activity of the histone methyltransferase.

Dot1结合到染色质通常出现在H2B－K123没有泛素化的状态，暗示泛素化并不调节酶的募集，但调节组蛋白甲基转移酶后续作用的活性。

Signalling through CXCR4 mediates actin polymerization and pseudopodia formation in cells, and induces chemotactic and migration to target organs. In addition, CXCR4-SDF-1 axis can promote tumor angiogenesis and growth.

CXCR4在肿瘤组织中的表达明显高于正常组织，而肿瘤常见转移部位均为CXCR4的配体基质细胞衍生因子-1(stromal cell derived factor-1，SDF-1)表达丰富的器官，SDF-1与CXCR4结合后可使细胞肌动蛋白丝聚合，形成伪足，从而定向诱导肿瘤细胞迁移到特定的靶器官；此外，CXCR4与其配体SDF-1相互作用可以促进局部新生血管作用，利于肿瘤生长。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
