A double-crystal XRD study of Ge/Si short period superlattice;

The seismic data corrections of short period auto-floating ocean bottom seismometer;

The theory of the Earth tides with short periods was summarized,and the UT1 time series was analysed.

This paper presents the configuration,design principal and performance of a blowdown short duration turbine test rig newly built by Institute of Engineering Thermophysics(IET) of Chinese Academy of Sciences.

Based on the analyses on the working characteristics and operating speciality of blow-down short duration turbine testing rig,a method for measuring the turbine performance on this type of rig has been presented,and an analysis on the uncertainty of the method has also been made in this paper.

The operation principle of a fast acting valve, which is one of the key facilities of the short duration turbine test rig, is introduced, the mathematical modei and calculation method have been presented, and the design performance parameters have been predicted.

Study on Oriented Cultivation of Industrial Timber for Short-period Fiberboard of Poplar

The undergrowth plant diversity and biomass of two short-period plantations were investigated between October and December 2007,which the natural vegetation recovery of shrub-herb slope was used as control.

Methodologies, principles and characteristics of some advanced short cycle, full-scaled turbine stage test rig are introduced in this paper.

Cultivation of high-yield,short rotation,medicinal plantation of Taxus wallichiana var. mairei

The growth factors of the stands of 4 Eucalyptus clones (U 6, W 5, EC 1 and Eucalyptus urophylla) of short rotation were investigated.

W5 eucalyptus clones short-rotation industrial raw material forest ownered by Leizhou Forestry Bureau were selected to be the object of site quality evaluation,the relations among tree height,DBH,and age were analysed by forest resources survey data.
