(1) Studies have shown that undulatory propulsion with long fins has advantages in stability, maneuverability, and low-speed retaining.

(2) The union real estate economical cycle undulatory theory, analyzed the real estate cycle undulatory theory to construct the real estate market risk early warning the guiding sense.

(3) The huge undulatory property makes the investor to tremble with fear, but one week heartless falls suddenly before this compares should be a good change.

(4) Particularly, the swimming velocity and thrust generated by undulatory motion of the developed robotic fin are analyzed theoretically.

(5) The undulatory biomimetic propulsor is a new underwater propulsor which swimming mode of Gymnarchus Niloticus.

(6) We established a kinematic model of the long-based undulatory fin on the basis of analyzing the long-based dorsal fin locomotion and considering the fluid-structure interaction.

(7) The undulatory biomimetic propulsor is a new underwater propulsor which emulates the swimming mode of Gymnarchus Niloticus.

(8) According to inertia principle, rail undulatory wear inspection system adopts analog digital composite filtering method to process data and eliminates the speed influence on measurement results.

(9) In the foundation of cycle undulatory theory, the booming theory founded the booming index, using it to monitor the influence of macroscopic economy by cyclical undulation.

(10) To realize the undulatory control of the flexible fin, a locomotory model is analyzed and a distributed control structure is designed.

(11) Such is the undulatory nature of the movement of opposites in all things.

(12) It is an important test platform supporting the study of underwater vehicle based on undulatory propulsion of long flexible Fin.

(13) Employing the fundamental principle of linear filter model, an improved simulation method is developed based on a high-order filter model for randomly undulatory sea surface.

(14) Modular design, Control system, Mechanism system, Biomimetic Robot Fish, Oscillatory propulsion, Undulatory propulsion.

(15) The melody of the story won't be so euphonious and undulatory.

(16) The first part of the thesis has expounded the cycle undulatory theory and financial early - warning theory.

(17) The investor may consider through the Dow Jones Index daily option direct investment undulatory property, once news releasing, has the large fluctuation(), then gains the security profit.

(18) In the third quarter the sign Pu 500 indices fall approximately 9%, more importantly, market undulatory property sharp increase.

(19) The changes and developments are also seen to be in many cases undulatory.

(20) It combines the fuzzy controller and the self-adaptive unit, achieving the undulatory control of the flexible fin in uncertain environments.

(21) The thrust and propulsive efficiency of the long-based fin undulating can be analyzed by applying the derived kinematic model and the equilibrium equations of the undulatory fin.

(22) It can move forward, backward or brake depending on the undulatory motion of the flexible fin.
