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。

We sought to identify and improve our compliance rate for the documentation of arterial catheterization in the perioperative setting.

The characteristics of pressure fluctuation in a standpipe at negative pressure gradient were investigated based on measurement in the gas-solid two-phase circulating fluidized bed.

通过对气固循环流化床负压差下料立管的压力测量，分析了立管下料过程的压脉动特性。

A phase-shifted controlling PWM DC/DC full bridge converter with softswitching is proposed and used to realize a constant current power of20A(5～48V).This full bridge converter utilizes the transformer leakageinductance(or the resonant inductance in series with transformersprimary)and the autoecious capacitance of MOSFET to achieveZVS(Zero-Voltage-Switching),as a result it can decrease the switchingwaste,increase the switching frequency,and diminish the power bulk.

本文使用一种通过移相控制进行脉宽调制的软开关全桥变换器来实现20A(5～48V)恒流源，这种全桥变换器利用变压器的漏感、原边串联谐振电感和功率管的寄生电容来实现开关管的零电压开通，降低了开关损耗，提高了开关频率，减小了电源体积。

The steady state and dynam ic characteristics of ASVG are analyzed with the help of this model.

通过对仿真结果的分析，得出了 ASVG的输出电压与它和系统接入点电压间的相角差、ASVG晶闸管触发脉冲、触发脉宽之间的关系，这为ASVG的触发脉冲和触发脉宽的设计提供了依据。
