The results show that rising of groundwater levels after water transportation plays an important role in the decreasing in the crown loss of Populus euphratica, and the crown loss of Populus euphratica gradually increases with increasing distance from the river course. The trees crown loss was less than 10%, which mainly was distributed within 100 metres to each side from the river course. The proportion of crown loss of overmature and effete forests were 50%-75% within 200 to 400 metres.

应急生态输水后地下水位的抬升对胡杨树冠疏失度的降低产生一定的作用；总体上，胡杨的树冠疏失度随着离河道距离的增加逐步增大，而且离河道越远，疏失度增加的程度就越大；树冠疏失度小于10%的旺盛胡杨主要分布在离河道100m之内，其中多以疏失度少于50%的长势较好的胡杨为主。

Firstly the oxidation loss was controlled by the reaction between the coated C/C composites and oxygen. Secondly the oxidation loss was controlled by the producing and vaporing rate of the glass. The oxidation loss was lined with the oxidation time. Thirdly there were cracks in the coating and the deep of the coating was oxidated. The weight loss rate increased linearly and the matrix had been oxidated partly in the end.

In order to make the right evaluation of the state which is the consumption consume of the steam line system, we make an test of the heat loss of the steam line network. And we also probe into the heat loss of the steam line system and the factors.
