It is equal to abandoned this part of material of nib lost and sharpens the saw-dust lost with the wooden pencil in fact, Because in 95%, the lead clothing pencil the raw materials utilization ratios of it material-saving the wrapping up core lead part removes the space of blind hole part of filling in backs end of pencil stub that are taken up of post of handle of pencil, The plumbaginous clothing material sharpens the saw-dust equivalent of material lost to consume with the wooden pencil basically, The pencil utilization ratio of raw materials produced with the timber is in 30-35%, a finished product pencil can only use two-thirds in using, Back one-third is abandoned, so the material-saving pencil is still pencil province of material-saving raw materials compared with wooden pencil.

被弃掉的笔头这部分材料实际上是与木制铅笔削掉的木屑是相等的，因为，节材铅笔它的原材料利用率在95%，铅衣包铅芯部分除去铅笔柄柱塞所占的铅笔头后端的盲孔部分的空间，铅衣材料基本和木制铅笔削铅衣削掉的木屑材料等量耗费的，而用木材生产铅笔的原材料利用率在30%-35%，一支成品铅笔在使用中只能使用三分之二，后三分之一被弃掉，所以节材铅笔与木制铅笔相对比还是节材铅笔节省原材料。

Of 12 tomato lines, the analysis on the 4 fruit nourishment quality traits (the contents of vitamin C, total soluble solids and dry matter and ratio of sugar-acid ) was carried out to study the four kinds of disparities, which included the interspecific one, the one between two varieties in the same species , the one between the lines bred by different means in the same variety ,and the one between the different fruit-shaped lines in the same variety .The analytic method of orthogonal comparison of single degree of freedom was applied. The results showed that the line of Lycopersicum pimpinellifolium was better than the average of the lines of L.esculentum in the 4 traits at significant level of 1%, the average of the lines of var.cerasiforme was better than the average of the lines of var.vulgare in the 4 traits at significant level of 5% or 1%,and the two space mutation line(YH02-2 or YH02-6) was better than the average of the other lines of the same variation in the 4 trait, respectively, at significant level of 1%. Of the lines of var.cerasiforme , the lines with pear fruit were lower than the average of the lines with round-shaped or plum-shaped fruits in the 2traits(the contents of vitamin C and total soluble solids), at significant level of 1%,the lines with plum-shaped fruits were higher than the average of the lines with round-shaped fruits, at significant level of 1%,and the lines with yellow-colored fruits(YH02-11) was lower than the average of the lines with red-colored fruits(YH02-1and YH02-7) in the trait of the contents of vitamin C.

The paper puts forth that the numerical model of actual forming part is reconstructed by RE and the surface is regarded as actual trimmed surface, then grids and nodes mapping relationship between design model and actual forming part is acquired through compelling deformation simulation, and the design trimming line is dispersed into points according to a certain precision and the projective points and the coordinate values of the intersection points of projective line on the grids formed by discrete points are calculated along trimming direction, the new coordinate values of projective points and intersection points of projective line after deformation are calculated based on the mapping relationship of grids and nodes, the deformed trimming line can be acquired through fitting the points into curve.

本文提出通过逆向工程技术重构出实际冲压件的型面并以此型面为修边后实际冲压件的型面，然后采用强制变形仿真的方法建立设计模型和实际冲压件重构模型的网格和节点映射关系。将设计修边线按一定精度离散成点，然后根据修边方向计算出各点在网格上形成的投影点和投影线交点，根据之前计算出来的网格和节点映射关系就可以计算出投影点和投影线交点在变形后的新坐标，将其拟合成曲线就可以得到变形后修边线的形状。
