Quasi elliptic filer is a novel high performance filter. Due to its complicated prototype and poor efficiency to extract parameter with classic method, its application has been confined. 准椭圆函数滤波器是一种新型的高性能滤波器形式,但是由于其原型电路的形式比较复杂,用经典综合的方法提取其参数的效率很...
In a true experiment, the control and experimental groups are randomly assigned. That is not the case in a quasi-experiment, which may be due to practical or ethical reasons. What is a true experimental method? A true experimental method is an experiment conducted to prove or disprove a caus...

a long quasi-static slip stage with a gradually increasing slip rate (0 – 1.6 μm/s) precedes the final seismic slip event (at a rate of 1.1 –2.6 mm/s). This study simultaneously considers the (1) irregular fracture surface, (2) true triaxial stresses, (3) high temperatures...
The study was designed as a quasi-experiment, taking two natural classes of the first graders in a senior high school as the subjects, experimental class and control class. 研究按照准实验来设计,采用两个高中一年级的自然、平行班级作为研究对象,一个实验班,一个对照班。 9. 43kb She was much...

This characterization of Piaget’s theory as quasi-interactionist, at best, is supported by Rosenthal and Zimmerman (1978) who state: We [have] characterized Piagetian and other, closely related structural positions such as Kohlberg’s view of moral development as basically nativistic, a conclusion...
