研究表明：在有互花米草的滩涂上人工种植的无瓣海桑，在其生物量小于互花米草生物量时，初始生物量大的超过互花米草所需时间短于初始生物量小的；当无瓣海桑生物量超过互花米草生物量后，无瓣海桑生长基本不受互花米草的影响，同时互花米草的生物量开始下降。

After being prefabricated, they will be carried to the point, and installed on the bridge. Seated very close to each bridge, prefabrication sheds are responsible for prefabricating girder boards and culvert cover boards. Dadoes are set up according to the number of girder boards.

The results show that the dissolution process of prefabricating alloy can be divided into two periods when the temperature of zinc melt is below the melting point of aluminum.Firstly,zinc melts infiltrates into the prefabricating alloy and then Zn-Al-TiC alloy forms in the surface layer of the prefabricating alloy.Secondly,the Zn-Al-TiC alloy of this alloy surface layer begins to dissolve to the zinc melt.

结果表明：当锌熔体温度低于铝熔点时，预制合金的溶解可分为两个阶段：第一阶段为液态锌向预制合金中浸渗，并在预制合金表层内形成Zn-Al-TiC合金；第二阶段为预制合金表层内的Zn-Al-TiC合金开始溶解并进入锌熔体。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
