The natural vibration spectrum curve is measured and the critical velocity to induce trashrack bar galloping is calculated. the effect of bar spacing on the bar strain and the characteristics of the exciting force are discussed. by fatigue analysis it is obtained that the service life of weld at the fixed end of the bar is about 13
分析了發電工況和抽水工況時的振源特性，討論了柵條凈距對柵條應變的影響，按鋼結構設計規范對柵條進行了疲勞計算， 1 ~ #測點處可視為不會發生疲勞破壞， 2 ~ #測點焊接處的疲勞壽命約為13 . 6年。 -
In this paper, a three dimensional finite element analysis has been used to analyse the loading stress of utw pavement. the critical loading position of utw plate and the rules of the effect of the joint spacing of plate, the thickness of overlay, ec / es and the interface conditions between concrete overlay and existing ac on the stress are provided
本文採用三維有限元法分析了utw路面荷載應力，確定了路面板的臨界荷位，得出了板接縫間距、厚度、板與地基模量比（ ec es ）和層間接觸狀況對應力的影響規律。 -
Combined with the percolation theory of low permeability oil reservoirs, we derived the function of determining critical technological spacing in low permeability reservoirs, and provided the theoretical basis for determining reasonable well spacing density during the development of low permeability oil reservoirs

The content of pema affects on interplanar distance of pe / mmt composite. the content of pema increases as the interplanar distance, barrier properties and melting point of composites increased, when the critical content of pema ( wpema = 30 % ) could get exfoliated composites. the interlayer spacing of pe / mmt composites depends on content of mmt, but not the content of mmt increases as the interlayer spacing increases
同時用x射線衍射（ xrd ）衍射實驗、紅外光譜（ ir ）實驗、差熱分析試驗（ dta ） 、力學性能測試等手段，研究了採用不同的相容劑改善聚乙烯與蒙脫土之間的相容性的情況；相容劑的用量對聚乙烯/蒙脫土復合材料層間距、性能的影響；蒙脫土的含量對pe / mmt對復合體系的層間距影響；以及工藝條件對復合體系的層間距和性能的影響。
