1 What is the largest air-breathing creature ever to inhabit the earth?

2 There is no hard-and-fast divide between water-breathing and air-breathing animals.

3 Experimental investigation on air-breathing mode of laser propulsion .

4 Regards , air-breathing restore , breath loosens.

5 Odobenocetops was an air-breathing mammal so had to rise to the surface in between dives.

6 The operation cycle and thrust calculation method for air-breathing pulse detonation engines are introduced.

7 The ultimate goal is Skylon, an unpiloted, air-breathing vehicle that takes off and lands on a runway, and can travel beyond Earth's atmosphere.

8 As the air-breathing engine, the performance of solid rocket ramjet is determined not only by structure of engine and the performance of propellant, but also by flight condition.

9 An air-breathing valveless PDE model was designed and manufactured, which was made up of subsonic inlet, mixing chamber, ignition chamber, detonation chamber and nozzle.

10 Mechanism analysis and numerical simulation of air-breathing model for laser propulsion .

11 It provides buoyancy and this, for the bulk of the descendants of these air-breathing pioneers, became a more important faculty.

12 For instance, a swim-bladder has apparently been converted into an air-breathing lung.

13 In the experiments, it was found that the momentum coupling coefficient of multi-pulse propulsion was lower than that of the single pulse case for the air-breathing mode.

14 Its cathode end plate had the structure of no - flow field, air of cathode diffusion by the means of air-breathing .

15 The gas would have the dual effect of choking air-breathing animals and preventing sunlight from reaching Earth's surface.

16 The spectrum of laser - induced plasma, the distribution of characteristic lines, and the temporal behaviors of plasma in air-breathing mode were introduced in detail.

17 The 90-metre-long craft's secret weapon is a hydrogen fuel-powered rocket engine called SABRE (Synergistic Air-Breathing Rocket Engine) and was designed by the company's managing director Alan Bond.

18 Chagrians were born as tadpoles in clutches of three or more, and raised in tubs of water in a family's private home. During this time, their arms, legs, and air-breathing lungs were developed.

19 Through ground test and hypersonic flow research, he made great progress in air-breathing hypersonic technology.

20 And the comparisons between the model and the theoretical analysis show that the research is feasible to use commercial software to analyze the air-breathing action of the fluid-flow.

21 But to 19th-century naturalists such as Charles Darwin, these air-breathing, warm- blooded animals that nurse their young with milk distinctly grouped with mammals.

22 In the study of open type flow - field plate design, the experiment results indicate the performance of air-breathing DMFCs could be enhanced by increasing the open area ratio.

23 A 100 J TEA CO2 laser was employed to study the effects of variety of pulse energy from 13 J to 80 J on the momentum coefficient for air-breathing mode.

24 In this type of breathing , employed by modern amphibians and air-breathing fish, the mouth cavity expands and contracts like bellows to gulp air and force it into the lungs.

25 Huebner said it was the first time an " air-breathing " jet had ever traveled so fast.
