Regarding the reciprocal lattice primitive cells basic vectors as two line space basic vectors, this paper finds a new matrix method to work out the reciprocal lattice primitive cell.

视正格子原胞基矢和倒格子原胞基矢为线性空间的两个基底，提出了求解倒格子原胞的一种新的矩阵算法。

It is proved that the volume of Brillouin zone and that of the reciprocal lattice primitive cell are equal for BCC lattice and FCC lattice in three dimensions by a simple mathematical method.

用简单数学方法就体心立方晶格和面心立方晶格证明了三维情况下布里渊区体积等于倒格子原胞体积。

Microscopically, the granulosa cell tumor attempts to form structures that resemble primitive follicles, as seen at the left. Most of these tumors are histologically benign, but some are malignant.

镜下，颗粒细胞瘤趋向于形成类似于原始的滤泡的结构，如图左示。大多数在组织学上呈良性，但一些是恶性的。
