spring
Here the bridge is seen as a vibrating beam supported by cables, which are treated as spring with a one-sided restoring force.
      
The peak values of fine root biomass were observed both in spring and in autumn, but SRL and RLD were the highest in spring and lowest in autumn.
      
Specific root length and root length density were higher in spring and summer, which means that fine root diameter was thinner.
      
A mass-spring-damper dynamics model of FS system was proposed and the hysteresis characteristic of the FS system was analyzed.
      
According to the design features of a hydro pneumatic spring, the necessity of a separate damping valve is proposed.
      
In the next spring, EI populations will recover more rapidly than EF populations.
      
Feeding habitats of blue sheep (Pseudois nayaur) during winter and spring in Helan Mountains, China
      
The feeding habitat selection of blue sheep (Pseudois nayaur) was studied by direct observation method in the Helan Mountains, China during winter (from November to December) and spring (from April to June) from 2003 to 2004.
      
Similar to habitat selection by the species during winter, blue sheep also showed a preference for mountain savanna with tree dominated by Ulmus glaucescens and medium tree density (>amp;lt; 4 individuals / 400 m2) during spring.
      
The level of temporal niche overlap in spring and autumn was low while in summer it was high.
      
Habitat selection of the Tibetan Snow Cock Tetraogallus tibetanus in the spring in Lhasa
      
However, in terms of temporal variations, higher δ18O in precipitation during spring is linked to small moisture flux while low δ18O in precipitation during summer is linked to large moisture flux.
      
The structure-foundation system is transformed from an original open system into an approximately hermetic system through a viscous-spring artificial boundary.
      
The data showed that the resistance-inducing concentration of arachidonic acid was 10-6M in autumn and 10-9M in spring.
      
The formation of soluble phenolic compounds, including flavonols, was studied in winter (Erythrospermum , Lutescens 230, and R 47-28) and spring cultivars (Lada) of wheat (Triticum aestivum L.).
      
These results illustrate the similarity of phenol metabolism in leaves of winter and spring wheat cultivars.
      
Protein markers of plant traits in breeding spring wheat for grain yield and quality
      
A problem of control of a mechanical system is considered that represents two mass points connected by a spring and moving along parallel straight lines.
      
It is assumed that masses of the points and the rigidity of the spring are unknown and the points are subject to forces of dry friction with unknown variable coefficients.
      
The number of males could exceed 1.5-fold that of females during the period of mass reproduction in spring and summer.
