It is possible to produce low-titanium aluminum alloy directly. Three months of periods of industrial test for production low-titanium aluminum alloy was conducted using the 80kA prebake electrolysis cells. The test results showed that the electrolysis cell can work stably, and the effect of TiO2 added into electrolyte on electrolytic process parameters, current efficiency, consumes of materials and energyare trifling. The titanium content in alloys is stable and the absorbility of Ti is high. The microstructure of electrolytic low-titanium aluminum alloy is homogeneous. The grain refinement effect is excellent comparing with that of alloys added titanium by melting Al-Ti master alloys and both alloys have the same grain refinement trend.

Effect of protein and lipid in rice on starch physicochemical characteristics, difference between the region of non-chalkiness and chalkiness of rice, dynamic variation of cell structure and CaM distribution on rice spike were expounded in this study. It was found that protein and lipid in rice had important effect on starch gelatinization, there were distinct differences between the region of non-chalkiness and chalkiness of rice, vascular bundle system in rice spike was changed during grain filling, difference quality of different position of rice spike was more distinct in dense spike rice for more powerful vascular bundle system, the development of rice seeds was corresponded to pericarp development, difference quality of different position of rice spike was also related to transport function of rachilla besides activity of "source", and calmodulin relative activity was closely related to grain filling velocity and enginery properties.

通过实验发现：稻米中蛋白质、脂肪对淀粉的糊化过程有着较大的影响；精米的非垩白与垩白部位以及心白与腹白部位之间在蛋白质、氨基酸含量及组成方面存在着明显差异：水稻穗部大维管束面积以及主穗轴维管束数目在灌浆过程中存在明显的动态变化趋势；密穗型水稻强势粒的维管组织比散穗型水稻发达，致使其强、弱势粒维管组织差异明显加大；果皮的发育与籽粒发育状况是相适应的：强势粒和弱势粒在灌浆生理方面的差异，不仅表现在籽粒本身的&库活性&上，而且也与其着生小穗轴的输导功能有关；CaM相对活性与水稻灌浆速率、机能特征间存在着密切联系。

It was observed in the Cr-Ni-Mo steels that the intergranular ductile fracture is caused by the reprecipitation of MnS particles in the steel with ordinary S content, and the overheating is also performed by the repreeipitation of AlN or VC particles along the prior austenite grain boundaries in one containing low S. Thus, a proposal seems to be made that the mechanism of overheating of Cr-Ni-Mo steels is related to the solution and reprecipitation of MnS, AlN or VC particles along the prior austenite grain boundaries.

MnS粒子的重新析出使普通硫含量的Cr-Ni-Mo钢发生沿晶延性破断，而AlN或VC粒子在高温奥氏体晶界的重新析出也能使低硫的Cr-Ni-Mo钢过热。

Meanwhile, the surface layer gets fine crystal grain with dispersive and homogeneous distribution of WC grains and Co binder from rapid melting and resolidification during HIPIB irradiation. Minimizing the mean free path in Co binder by decreasing the WC grain size leads to an increase in resistance to plastic deformation in the binder.

HIPIB强烈非平衡作用下的重熔和再结晶使WC晶粒细化且分布更均匀，同时，表层析出弥散分布的Co_3w_9C_4相，使Co粘结相产生强化，导致Co粘结相的平均自由程降低，从而增强了Co粘结相抵抗塑性变形的能力，提高了辐照硬质合金的耐磨性能。

该复合颗粒的制备为研究电磁场作用下颗粒的运动行为以及用电磁流变技术制备光子晶体提供基础。

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。
