沙障

综合分析认为PLA沙障具有很大的发展潜力及广阔的推广应用前景。

So by integrated analyzation , PLA sand barrier has prodigious development potential and widely popularization and application foreground .

PLA沙障及麦草沙障单个障格内的土壤硬度分布都是不均匀的，并且二者的土壤硬度分布规律存在差异。

Top soil hardness in single barrier grid of the PLA sand barriers and straw sand barriers was uneven distribution .

PLA沙障设置一年半以后，材料平均分子量有所下降，但降幅不大，纤维表面整体保持完好。

After the barrier set 1.5 years later , the fiber average molecular weight has a small decline and its surface keep well .

PLA沙障在参考传统方式设置时即起到了很好的防护效益。

Improved materials almost have no influence on the construction speed . ( 2 ) PLA sand barrier which set by the traditional style can take a good combat effect .

地下部分的沙柳沙障腐蚀比地上部分严重。

And the corrosion of underground sections of Salix sand barrier were severe than the aerial parts .

不同风速下，不同规格沙障间积沙厚度差异显著。

The thickness of deposited sand have notable difference to different size barriers with different wind speed .

障前、障后风速降低是土工格栅沙障防沙的主要机制；障中的增速区是引起沙障中部不积沙或少积沙的诱因。

It was the preventing mechanism of barriers to decrease wind speed and deposit sands before and after barriers .

障中的增速区是引起沙障中部不积沙或少积沙的诱因。

And the wind speedup region of middle barriers provided occasion for no or less deposited sand in barriers middle .

在沙障带间栽植刺槐，成活率提高了58.4%，且生长情况良好。

The survival rate of locust planted between the belt barriers increases by 58 . 4 % , and it grows well .

沙障受风蚀率可能还与喷洒时的压力、风速等因素有关。

Furthermore , the erosion rate of soil coagulant sand-barrier likely to relate on the nebulizer pressure and wind speed in insufflation process .
