The sheath-core ratio, compounding ingredient of the sheath ,chip drying process and drawing process were discussed for the composite spinning of low-melting point and normal polyester chips.

研究了低熔点聚酯切片的流变性能，以及低熔点聚酯与普通PET皮芯复合纺丝时的皮芯层复合比、皮层组分配比、切片干燥工艺和纤维拉伸工艺。

Results:Methyl aldehyde can"t preserves efficiently the ultrastructure of the renal biopsies.Osmium tetroxide can preserves efficiently it but affects dyeing of the section for light microscopy.However,glutraldehyde not only preserves it better than methyl aldehyde but also doesn"t affect dyeing of the section for light microscopy.

结果：甲醛固定不能有效保存肾穿组织的超微结构，锇酸的固定能有效地保存超微结构，但严重影响了光镜切片的染色；而戊二醛与甲醛相比，较好地保存了肾穿组织的超微结构，同时又不影响光镜切片的染色。

Historically, critical technical advances made during the mid and late 19th century, including the development of the first high-quality microscopes, the manufacture of synthetic stains, the discovery of effective tissue fixation and embedding techniques, and the development of modern-style microtomes for cutting thin tissue sections produced the first revolutionary shifts in brain tumor classification.

历史上，在19世纪中期及末期出现的重大技术进步，包括第一台高质量显微镜的发展，人造染色剂的制造，有效的组织固定和包埋技术的发明，能够切割较薄组织切片的现代设计切片机的发展等，促成了第一次脑肿瘤分类的革命性变化。

Since a skeleton pixel should be in the middle point of one of a pair object boundary, based on the discussion of some commonly used thinning algorithms, a fast thinning algorithm based on midpoints of multi-orientation slices was put forward.

在对几种常用细化算法进行探讨之后，提出了利用骨架上的像素点至少在某个方向上应处于该方向对象边界的中心点处的特点，从多个方向对细化对象进行切片，并利用这些切片中心点集作为原始数据集，以快速产生对象骨架的方法。
