Mechanism of the allosteric change Oxyhemoglobin ahs a different quaternary structure from deoxyhemoglobin. As O 2 binds to the Fe 2+ it distorts the heme group and moves the proximal histidine. This in turn moves helix F and alters the interactions between the four subunits.

变构转变的机制：脱氧血红蛋白与氧合血红蛋白有不同的四级结构，当 O 2 结合到 Fe2+时，使血红素基团变形并移动邻近的组氨酸，随之移动螺旋 F 和改变四个亚基间的相互作用。

When oxyhydrogen free radical release the dummy man smell, directs effectively the mosquito.

氢氧自由基释放时模拟人体气味，有效把蚊子引过来。

When smooth accelerant is shot by illumination, change smooth energy into electron and cavity above all, next with the oxygen in air (O2) and water element (H2O) reaction, the oxyhydrogen that generates a freeboard oxidation capacity is free base and oxygen anion (O2-).

光触媒被光照射时，把光的能量首先转化成电子和空穴，然后与空气中的氧气(O2)和水分子(H2O)反应，产生具超高氧化能力的氢氧自由基和氧负离子(O2-)。

As to manufacturing a Φ1800mm, F/1.5 large paraboloidal mirror, three structure models with different thickness of base plate were calculated and analyzed respectively.

以加工Φ1.8m、F/1.5的大口径抛物面主镜为参照，分别对三种结构模型在不同基盘厚度时进行了变形仿真计算。

The results indicate that the partial substitution of Cr for V is favourable for increasing the activation of TiMn-based alloys.

结果表明，Cr部分取代V能够提高TiMn基合金的活化性能，当Cr含量为0.01时，获得了397mAh／g的放电容量。

In order to solve the problem that matrix A often occurs irreversible when shape function is calculated by using traditional element free Galerkin method, the orthogonal function with the weight function is utilized in the paper. And partition of unity quadrature technique is employed and so a truly "meshless" method is realized.

针对传统无网格伽辽金方法在构造形函数时，矩阵A容易出现不可逆的弊端，采用带权正交基函数构造形函数，在积分方案上采用单位分解积分方法，从而实现了真正的"无网格"。

We described the cytologic features of pemphigus vulgaris on a TP smear and compared them with those of neoplastic conditions.

我们将液基细胞学涂片中寻常天疱疮的细胞学特点进行描述，将其与肿瘤时的特征进行比较。

Herbert Burdenski was wearing these boots when he scored the first postwar goal for Germany with a penalty shot resulting in a 1:0 win for Germany.

赫伯特布尔登斯基穿着这些鞋时，他拿下了二战后的第一个目标是德国一个罚球导致在1：0赢德国。

Perceptively on 3d and 5d. Collagen is positive in Western blot on 9d. Aniline dyeing is positive on 12d. The control group was negative. Ad-BMP-2 transferred MSCs cultured in fibrin gel was positive in Aniline dyeing, Immunohistochemical. The therapy effect of group was better in histology, biochemistry and biomechanics in all periods than the other two groups, and was similar to the natural cartilage.

结果 ①Ad-BMP-2转基因MSC BMP-2、CollagenⅡ的PT-PCR分别在3、5d呈阳性，CollagenⅡ的Western Blot 9d为阳性，较对照组有显著差异；②转基因MSC经纤维蛋白体外三维培养后免疫组化和苯胺蓝染色呈阳性，电镜显示细胞生长良好，有基质合成；③转基因修复组各时期大体、组织形态学和组织化学成份均显著优于其它两组，12W时力学和组织学已接近正常关节软骨。
