查询词典 trace function

Particular configurations on bedding planes and on the surface perpendicular to the bedding planes lead to different explanations for the genesis of these silty dykes:(1) they are considered as the oldest trace fossils of metazoan according to the spindle-crack of siltstones on the bedding plane and the sand-filling tube configurations on the surface perpendicular to the bedding plane;(2) they are considered as the liquefied sand-veins induced by earthquake according to the sinuous configuration of siltstone dykes on the surface perpendicular to the bedding plane and the obvious liquation feature.

由于该粉砂岩岩墙在层面上和层内具有特别的形态，因而对其成因具有多种解释：在层面上呈纺锤状粉砂岩裂缝以及在层内呈砂质充填管形态，从而被认为是最古老的后生动物遗迹化石；在层内呈弯弯曲曲的粉砂岩岩墙以及明显的流体化作用特点，所以又被解释为地震振荡作用形成的液化砂岩脉。

The works in the project just done can be summarized as five respects.(1) A device was designed to fabricate the asymmetrical resonant cavities by a pendant drop. A series ARCs with variable parameters provides a valuable experimental method for investigating the characteristics of ARCs.(2) The relationship between the number of active modes and the shape parameters in an ARC was investigated. The experimental lasing threshold was compared with theoretical result, the good agreement between two shown that it was the decrease of the number of active modes in an ARC that decreased lasing threshold.(3) Dye lasing gain was used to enhance the signals of stimulated Raman scattering of the weak gain Raman modes in a circular cavity made by a pendant drop, the instantaneous SRS spectra of weak gain Raman modes in ethanol was obtained by this new method.(4) The SRS signals of minority compound in a binary chemical complex was obtained by using dye lasing gain method. The detection concentration of minority compound was reduced to an order compared with normal SRS method.(5) A cylindrical circular cavity was formed by a liquid jet, which was used to reduce the pump intensity required for laser induced plasma spectroscopy. The limit of detection of trace element in aqueous sample was greatly decreased by this new method.
