1 Whales use their pectinate teeth to gather plankton.

2 The pectinate quills of the porcupine are barbed.

3 METHODS Rutin calcium pectinate pellets were prepared by in-liquid solidifying method, the best parameters were chosen and its release properties in different media was evaluated.

4 According to direction, pectinate muscles could be divided into 3 types: convergent, network and mixing types.

5 The application of pectinate filter in the electromagnetic pollution precaution is explained. This filter is usually used in the design of some microwave heating equipment.

6 It proves by practising that this designing method of microstrip pectinate bandpass filter and interlaced digital filter is simple and of good effect.

7 The working properties depend on the gate bias voltage and the structure of pectinate Al electrode.

8 Objective To study the morphologic features of terminal crest and pectinate muscles in human right atrium and discuss their possible function.

9 The rotary brush comprises a plurality of radiating brush hairs which are arranged on at least one pectinate wool top; the pectinate wool top is winded into a spiral shape and fixed.

10 This paper introduces a digital noise generating system. It can generate three kinds of jamming noise such as broadband noise,[] pectinate noise and noise of concave frequency.

11 Standard microelectrode techniques were used to study the effect of berbamine on right atrial pectinate.

12 Methods With naked eyes we observed and measured terminal crest and pectinate muscles.

13 Proximal cords of entrance cord was terminal crest and pectinate muscle, and distal one was plexiform cords.
