不均匀的

The results show that Sb addition can diminish the crystal grain, but the content of segregative phase at crystal boundary increases, and the current efficiency of material is low. Compared with Sb addition, Sn addition can also diminish the crystal grain, the current efficiency increases, the content of segregative phase at crystal boundary reduces, but diffusional corrosion of the anode surface is not uniform. The cooperation of Sb and Sn can prevent Si from segregating effectively and enhance the current efficiency obviously. At the same time, anode materials have preferable surface dissolution characteristics.

结果表明： Sb具有细化晶粒的作用，但晶界存在较多偏析相，电流效率偏低；与Sb相比较， Sn也具有细化晶粒的作用，电流效率有所提高，晶界偏析相较少，但阳极的表面腐蚀溶解不均匀； Sn和Sb的协同作用在于能有效地抑制Si的偏析，显著提高阳极的电流效率，使得阳极表面具有良好的腐蚀溶解性。

The results show that mechanical heterogeneity has great influence on the J-integral of welded joint containing transverse crack. The J-integral on the path cross the interface between welded joint and base metal is higher than the J-integral on the paths in the weld metal for undermatched joint,while the J-integral on the path cross the interface between weld metal and base metal is lower than the J-integral on the paths in the weld metal for overmatched joint. Moreover,the difference of J-integral values increases with the increasing of the load and strength mismatching difference and the path-enclosed length of interface between weld metal and base metal.

计算结果表明：力学不均匀性对含横向裂纹焊接接头的J积分有重要影响，低匹配焊接接头中积分路径穿越焊缝与母材界面的J积分值高于积分路径在焊缝内的J积分值，高匹配焊接接头中积分路径穿越焊缝与母材界面的J积分值低于积分路径在焊缝内的J积分值；载荷越大，焊缝与母材的强度差别越大；积分路径中包含的焊缝与母材界面长度越大，J积分的差值越大。

An analysis is also made of the moving regular of particles, the leakage passage formation feature, and the particles displacement field and so on. The internal stability of soils is studied from the perspective of gradation. Results show that the stability of soils relates closely to the shape of gradation curves and coefficient of ununiformity.

The effect of the overlaying tiss ue on the measurement can not be ignored because the most interested tissue to b e monitored is the deeper tissue layers,such as muscle and brain,which are under adipose or skull.Apart from this,variations of the regional hemoglobin oxygen s aturation (rsO2),haematocrit and regional blood volume hav e their influences on the measurement.

然而在人体组织这个复杂的不均匀混合介质中，深层组织往往是感兴趣的待测部位，如皮脂下的肌肉组织，头皮和颅骨下的脑灰白质等，这时外层覆盖组织的存在会直接影响检测的精度；另外，全血的局部氧饱和度( rsO2)的波动，红细胞比容的变化，以及血容积都对测量精度产生影响。

Heat sintered ZrO_2 ceramic does not react with any acids and bases except HF. It can't be coarsened by the traditional pretreatment process. Through a great deal of experiments, author found a kind of coarsened prescription which can corrode ZrO_2 ceramic, forming many holes and troughs on its surface.

These five zones are as follows: the zone of the reaction synthesis of TiC, the zone of reaction completion, the zone of the growth and homogenization of TiC, the zone of ideal structure and the zone of coarsened TiC particulates.

结果表明：适当提高合金熔体的等温反应温度并选择理想的反应时间，可获得尺寸细小、数目较多且分布均匀的原位TiC颗粒；当合金熔体中TiC的合成反应基本完成时，凝固速度对组织中TiC颗粒的数量和尺寸的影响不是很大。

结果表明渗透过程直接影响树脂分布，从而影响纺织品的机械性质；足够的渗透是获得良好弹性所必要的，但是为达到树脂均匀分布而过分的渗透则是不必要的，强力损失曲线有一个最大值，这是实际生产中应设法避开的。

The transition radiation faculae on the rear side of a 20m thick target Ta was a smooth round structure with the center brighter than the periphery, indicating incoherent transition radiation and coherent transition radiation, which is close to the results of the theoretical simulations. For a 100m thick target Ta, the faculae was a star-structure and became smaller, which resembles a star-structure of the energetic proton emission. For a 10μm Ta+10m Cu+5m Ta composite target, the faculae was a ring structure and became bigger and non-uniform, looked like two apart faculae.

在厚度为20μm的Ta靶背表面观测到渡越辐射光斑呈现较平滑的圆形结构，而且中心亮度高于周围，这包含了非相干与相干渡越辐射的成分，与理论模拟结果接近；在厚度为100μm的Ta靶背表面观测到渡越辐射光斑呈现出星状结构，光斑较小，与高能质子发射出现的星状结构极其相似；在复合靶背表面观测到渡越辐射光斑虽然也呈现大致的圆形结构，但光斑较大，而且极不均匀，中间有很明显的光斑分裂。

设一未知的不均匀双轴性介质复杂物体掩埋在其中一空间中(不论是在半空间或三层空间中)，吾人可在另外的空间中适当的安排一组具有不同入射和极化方向的无关联波照射物体并量测在此之散射场，利用简单的矩阵运算，我们就可以克服非线性和不良情况的发生的困扰，进而重建双轴性复杂物体的介电常数分布。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
