The spatial interrelationships of osteon canals were studied in corrosion preparations with the help of rastral electron microscopy. The structure of microvessels, their belonging to a definite link of the microcirculatory bed, the interaction of vessels and their position with respect to the osseous matrix were studied in bone sections impregnated with silver nitrate after V. V. Kuprijanov. Haversian canals in the compact substance of the bone are longitudinally oriented, can duplicate and form a single system of canals. The neighbouring canals of osteons might be bound by means of Volkmann's canals. The investigation of the Haversian canals in serial sections has shown that the diameter of the same canals of osteons can change at different levels, the diameter of the osteons themselves remaining unchanged. This seems to speak of uneven development of osteons in their different parts. In the Haversian canal there are one-two or occasionally three vessels having all three links of the morphocirculatory bed. The course and ramification of the vessel are identical to the shape of the osteon canal which includes them. The vessels are closely connected with the bony matrix by means of connective tissue bundles directed from the canal wall to the vessel wall. These bundles appear to serve as a peculiar anchor or amortizing apparatus and its elasticity might be a factor of a change of the shape and direction of the canal vessels in the bone development process.
借助扫描电子显微镜，对腐蚀标本中骨单位管的空间相互关系进行了研究。在按照V. V. 库普里亚诺夫方法用硝酸银浸渍的骨切片中，研究了微血管的结构、它们属于微循环床的特定环节、血管的相互作用以及它们相对于骨基质的位置。骨密质中的哈弗斯管呈纵向排列，可重复并形成一个单一的管道系统。骨单位的相邻管道可能通过福尔克曼管相连。对连续切片中哈弗斯管的研究表明，骨单位相同管道的直径在不同水平可能会发生变化，而骨单位本身的直径保持不变。这似乎表明骨单位不同部位的发育不均衡。在哈弗斯管中有一两条血管，偶尔有三条血管，它们具有形态循环床的所有三个环节。血管的走行和分支与包含它们的骨单位管的形状相同。血管通过从管壁指向血管壁的结缔组织束与骨基质紧密相连。这些束似乎起到一种特殊的锚或缓冲装置的作用，其弹性可能是骨发育过程中管内血管形状和方向变化的一个因素。
