Based on the theory of shrinkage, capillary force theory, the influence of road concrete additives in common use on surface tension of water is studied, and the results show that the influence of water reducer is very small whereas shrinkage-reducing agent and air entrainer can reduce surface tension of solution significantly. The relation between surface tension and additive dosage are non-linear relation. Each additive has an obvious critical micelle concentration.

从混凝土收缩的基本理论——毛细管张力理论出发，通过道路混凝土外加剂对水的表面张力的影响研究发现，减水剂对水的表面张力的影响很小，而减缩剂和引气剂可以大幅度降低溶液的表面张力，溶液的表面张力随外加剂的掺量呈非线性形式降低，而且都存在临界胶束浓度。

It is important to find an additive that can reduce production costs and improve the integrative performance.

寻找一种既能降低生产成本，又能提高其综合性能的添加剂具有重要意义。

因此，在保证滤料达到较高的过滤精度情况下，如何提高滤料的透气度及提高表面光洁程度，减少粉尘附着，降低运行阻力是滤料生产厂首先应研究的课题。

Through research, give the following conclusion: there is no competition, lotus leaf fern and wire fern Adiantum as drought intensifies, the total biomass of a decreasing trend when the water content at the same time, with the intensity of Increase in total biomass showed an increasing trend, LAR general with the increase in soil moisture and lower, with light to reduce the increase, when in a kind of competition within and between species, the lotus leaf fern Adiantum the total biomass is still followed Such laws, but because the resources snatch the total biomass decreased significantly.

通过研究，得到以下结论：在不存在竞争的情况下，荷叶铁线蕨与铁线蕨随着干旱的加剧，总生物量呈降低的趋势；当处于同一水分含量时，随着光强的增加，总生物量呈增加的趋势，LAR一般随土壤含水量的增加而降低，随光强的增加而降低，当处于种内和种间竞争时候，荷叶铁线蕨的总生物量仍遵循这种规律，但是因为资源的抢夺造成总生物量明显降低。
