The density, electrical contact resistance and hardness of these two alloys were tested. The results show that Ag and rare earth oxide appear in Ag-Y and Ag-Ce alloy after internal oxidation. The distribution of oxide particles is inhomogeneous and seriously conglomerated in Ag-Y2O3 and Ag-CeO2 sintered bulk, but they are dispersed and uniform in Ag matrix after severe plastic deformation. The relative densities of wire materials are larger than 99% and the electrical contact resistances are low (＜2.2 μΩcm).

The digital watermark was hided by the modification of DCT coefficient of chromatism in the YC_bC_r, the matrix of chromatism was disparted into 8×8 blocks, which were divided into two types by the density of edge point, then the watermark components with different strength were hided into the blocks according to the classification.

利用彩色图像在YCbCr域内对色差分量的DCT系数的改变加入水印，将色差分量矩阵进行8×8分块，根据每个小块内边缘点的密度将所有小块分成两类，不同类的小块分别按照不同的拉伸因子，加入水印信息。

It was found that the composite structure of Ti-Si-N films, nanocrystalline TiN embedded in amorphous Si_3N_4 matrix, was confirmed in this work. The increasing deposition pressure resulted in the appearance of columnar structure, decrease in the film density, increase in the surface roughness, and deterioration of the adhesion strength and tribological properties.

The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.

除了对各个电子传递体（ FAD ，[2Fe-2S]，[4Fe-4S]，[3Fe-4S]以及血红素分子）进行精确定位外，我们在该结构跨膜区靠近线粒体基质一端的口袋 Qp 中，发现了一些电子密度，认为是所结合的辅酶 Q 的头部结构，这一点被与抑制剂结合的复合体的结构所证明，在该结构中， 2－ TTFA 恰好结合在口袋 Qp 中，同时，我们还发现了第二个2－ TTFA 的结合位点，位于跨膜区靠近线粒体膜间隙一端的口袋 Qd 中，这个发现具有全新的意义，将影响人们对电子在复合物 II 中传递以及辅酶 Q 在复合物 II 与 III 之间转移的认识，促使人们重新复合物 II 在线粒体呼吸链中的角色。
