Pore size measured from the as-synthesized particles is about 2.7 - 4 nm and this becomes slightly smaller after calcination which is about 3 - 5 nm.

TG/DTA中温度上升至约300 oC时，重量开始明显失重，随著合成反应温度上升，最终残留量由1~3%提高为约5~7%，动态光散射粒径分析发现随著乙醇含量增加，煅烧前与煅烧后的粒径尺寸均有下降趋势，随著水含量的增加，比表面积值随著下降，煅烧后的壳层孔隙尺寸约为3~5nm，煅烧前的壳层孔隙尺寸为2.7~4 nm，煅烧后的孔隙度会略为上升。

To solve the problem encountered in finding a proper rotation matrix and translation vector, approximate and precise solutions are provided successively. The approximate one has the advantage of utilizing existing solution, with limited range of weight to choose from. The precise one has no limit to weight, and can also prevent the problem of obtaining a mirror matrix of the correct one. Besides, it permits the'hat'to be amplified to fit the size of'head'.

其中近似解可以直接套用现成的公式计算，但是权重的选择余地不大，而精确解则无此限制，而且从理论上解决了不同权重下求解旋转矩阵和平移向量时，可能出现错误的旋转矩阵的问题，并允许在配准时对"帽"进行缩放以适应"头"和"帽"的大小不匹配的问题。

Pull one's 'weight do one's fair share in a job, project, etc 尽本分: We can succeed only if everyone in the team pulls his weight.

我们全队只有人人各尽所能才能取得成功。

In the production processes, the materials were arranged reasonably and the treating after the fiber dying was paid some attentions. It used the "light weight, low speed, large ratch, more carding and small dropping" principle in the carding process, and the "tight ratch, light weight, low speed" principle in the drawing and roving processes. The break ratch was let out properly in the spinning process. In the double twisting process, the differences of yarn doubling tension and spindle speed were reduced, the twist distribution was evenly in the compound yarn accordingly.

生产中，注意原料的合理搭配和染色后处理，前纺梳理工序采用"轻定量、低速度、大隔距、多梳少落"的原则，并粗工序则采用"紧隔距、轻定量、低速度"原则，细纱工序适当放大后区隔距，倍捻时尽量减少并纱张力差异和锭速差异，提高股线捻度分布的均匀性。

Through analyses, we can make the conclusion that, the relation of seed fresh weight dry weight and days after pollination, fat percent content, protein nut content, starch nut content can be expressed with Logistic equation; the change of kernel volume, moisture content of kernel and days after pollination accorded with three ascend curve equation. Kernel protein content, starch content and the changes of days after pollination tallied with reciprocal equation and they had high relation.
