While the internal pressure is low, axial load takes leading roles and prompts tube materials flow in the direction of branch tube that also helps to alleviate the over reduction of wall thickness.
Another is that it may result in great friction resistance between mold and tube, which will hinder the materials into branch.

Humidity controlling materials were mostly made from silica gels, minerals, inorganic salts and polymer.
Consequently the adsorption and desorption capacity and controlling rate of materials were obviously improved.

The catchment area of Jiasikou gully was about 95km2, both sides of the hill and gully bed provided rich solid materials.
The loose deposit thickness in formation area was relatively large, while accumulation materials were abundant (Fig.1a).
Source conditions In this project, we investigated 54 source points and found that the source materials type included collapse deposits and channel deposits mainly.
