1·In addition, closely arranged cuticle cells, epidermis cells, closely arranged pulp cells configuration and less cavum cells jujube fruits are more resistant crack varieties.
此外，角质层细胞、表皮细胞排列紧密，果肉细胞排列较紧密且果肉细胞间空腔较少的枣品种果实较耐裂果。
2·Based on the established kinematic model, the principle of the key pole length is proposed to avoid the cavum phenomena in the measurement range.
在所建立的运动学基础上，提出关键杆长的设计原则，以避免测量空间内出现“空腔”现象。
3·When it bucks, the buckling of model is different from other shells because it is constrained by the cavum.
当薄的衬壳发生屈曲时，由于壳体受到空腔壁的约束，因此它的屈曲行为与一般的壳体屈曲问题不一样。
