Currently has a class of calcium agents, such as amino acid calcium, Stachyose calcium, vitamin C calcium are among the elements of calcium, they can be absorbed by the body take the initiative and do not need the help of vitamin D, but it does not take elements of calcium Children do not need vitamin D, because the absorption of dietary calcium of vitamin D is still needed help.

目前有一类钙制剂，如氨基酸钙、苏糖酸钙、维生素C钙等都属于分子钙，它们可以被人体主动吸收，并不需要维生素D的帮助，但并不是说服用分子钙的孩子就不需要维生素D，因为食物中钙的吸收仍然需要维生素D的帮助。

Results showed that the length of phase D of male syconia was about one month, while the length of phase B of female and male syconia was 2-3 months. This means that phase B and phase D could not overlap completely, resulting in the falling of syconia in phase B due to lack of wasps for pollination.
