Extracellularly recording the responses of dLGN neurons to sinusoidal gratings with different orientations showed that optimum orientations of dLGN neurons in trained cats, compared with that in untrained cats, did not shift in favour of the trained orientation. For cells with receptive fields located within 15°visual acuity away from the foveae, there are no difference in orientation bias and firing rate at trained orientation between the trained cats and untrained cats.

细胞外记录外膝体背核神经元对不同方位正弦光栅刺激的反应显示，垂直或水平方位正弦光栅信号训练的猫，与正常猫相比，其外膝体细胞的最优方位并未向着训练方位发生明显改变，对于感受野位于中央区15 度视角以内的细胞来说，其方位选择性强度以及在训练方位的发放强度与正常猫无明显差异。

So in order to get recombinant NT-3, the rat NT-3cDNA was reconstructed in a mammalian expression vector and transfected into incasing CHO cells by liposome-mediated method. The clones of the cells transferred with rNT-3cDNA were selected by G418. The Chinese hamster ovary cell line stably producing recombinant rat NT-3 was established.

因此，为了获得基因重组NT-3，研究其生物效应，本文成功构建了重组大鼠NT-3基因真核生物细胞稳定表达载体，并利用脂质体介导，转染进CHO细胞；经G418筛选，建立了中国仓鼠卵巢细胞系，稳定表达重组大鼠NT-3。

The nuclear membrane invaginates and lysosomes are internalized.

The utilization of the XP1 will contribute the investigation of the role in the process of megakaryocyte differentiating, maturating and platelet formation. Our study would provide additional therapeutic drug as for thrombocytopenic patients.

这一新型的cMp1分子配体将会促进有关巨核细胞增殖和分化及其血小板产生的分子机制的研究，也为开发具有自主知识产权的升高血小板新药打下了基础。

The results show: TiC particulates can act as nucleates of α-Al and enter into α-Al during solidification. They also can act as nucleates of S' phase during ageing, there are a lot dislocations around TiC particalates, which accelerate ageing process of 2024/TiC composites.

研究表明：TiC颗粒能作为α—Al形核核心，在凝固过程中进入α—Al基体；在时效过程中，TiC颗粒可以作为S′相的衬底，其周围存在大量位错，加快了复合材料的时效进程。

During solidification,α-Al phase nucleates first in the interstices between the short fibers and grows gradually toward the surface of Al2O3 short fibers. The content of Cu and La element around the surface of Al2O3 short fibers increases, both of them enrich almost in the same region, but the content of Cu element in the interstices of short fiber decreases gradually.

结果表明：Al2O3纤维与基体间润湿良好，生成了致密的界面层；在凝固过程中，α-Al相在短纤维间隙中形核并向纤维表面生长，纤维表面Cu和La元素的浓度增大，纤维间隙中的Cu元素的浓度减小。

It is found that substructures of stress-induced εM are γlamellas and stacking faults. A new growing mechanism of stress-induced εM were raised, that is ε phase nucleates at many sites on parallel γlamellas and stacking faults,εM unit-layers join each other in length and combine in width.
