Specific embodiment
The invention provides a kind of plant for a long time exposed to the analogue means of shallow-water wave environment, different wave ginsengs can be realized
Under said conditions, research of the plant physiology and biochemistry response mechanism in long time scale.
Below in conjunction with accompanying drawing, the present invention is specifically introduced, so that those skilled in the art's accurate understanding is of the invention
Technical scheme.
Orientation as herein described, as reference, is upper perpendicular to the direction on ground when using with the use state of analogue means
Lower direction, vertical or vertical, under the direction for pointing to ground is, the direction away from ground is upper；With vertical perpendicular plane
It is horizontal plane, in the horizontal plane, the direction of motion is direction pointed when being moved parallel to plant cultivation box 2, for ease of retouching
State, fore-and-aft direction can be defined as, it is preceding to point to the direction of crank 3, after being away from the direction of crank 3；In the horizontal plane, laterally
It can be any one direction for intersecting with fore-and-aft direction in horizontal plane.
Because salt-marsh plants are grown on the shallow-water wave region after wave aufhellung, therefore mould only is carried out to shallow-water wave environment herein
Intend, the principle of analogue means is described in detail with reference to Fig. 1.
In deep-water weave, the movement locus from the water surface to water-bed portion's water particle is circle, but circular trace radius meeting
It is gradually reduced, until when the depth of water is L/2 (L is wavelength), the radius of circus movement track levels off to zero.In shallow-water wave, water quality
The movement locus of point is ellipse, and from the water surface to water-bed portion, oval movement locus gradually becomes flat, at water-bed portion, water particle
Movement locus is changed into straight line (assuming that the motion of water particle is irrotationality).
There is following relation in shallow-water wave between depth of water h and wavelength L：
H/L≤1/20 (formula 1)
Water particle velocity expression in the horizontal direction is in shallow-water wave：
In formula, u is water particle speed in the horizontal direction；H is wave height；G is acceleration of gravity；K be wave number (k=2 π/
L)；T is period of wave；X is the position of horizontal direction；T is the time.
Theoretical and experimental observation shows, shallow-water wave water particle in speed very little of the vertical speed compared to horizontal direction,
Can be ignored, therefore have ignored in shallow-water wave water particle herein in vertical flow velocity, by water particle vertical direction flow velocity
It is designated as zero.
As shown in figure 1, the crank OP in crank-link mechanism is under the driving of stepper motor, with R as radius, O points are circle
The heart is moved in a circle (circular dashed line in figure is the movement locus of P points), and then drivening rod PQ (length is l) is moved so that Q
Put and this horizontal direction does straight reciprocating motion in OQ with the Q rigidly connected objects of point.
Now Q points and below speed with animal body in the horizontal direction be represented by：
In formula, speed of the u ＇ by Q points and the object for driving below in the horizontal direction；ω is angular speed；θ is the t times
Interior rotational angle；T ＇ are the rotation period that stepper motor drives toggle.
When the length l of PQ is much larger than the length R of OP, i.e.,：l>>During R, Q points and the object that is driven below are in level
The speed in direction can approximate expression be SIN function：
Water particle flow rate expression in the horizontal direction is cosine function (formula 2), the thing that crank connecting link drives in shallow-water wave
Body movement velocity expression formula in the horizontal direction is SIN function (formula 5), and the two has mutual transforming relationship, simultaneous formula 2 and formula
5, for the x position for giving, if making both waveforms unanimously to derive：
T'=T (formula 6)
I.e.：The T-phase etc. period of wave of the rotation period T' of crank-link mechanism and shallow-water wave；For fixed depth of water h, crank
There is mutual transforming relationship in the crank length R of the connecting rod and wave height H of shallow-water wave.
As the above analysis, can be using the motion of water particle in crank-link mechanism simulation shallow-water wave.
Really as stated in the Background Art, push pedal is made unrestrained mode and can not for a long time make wave：On the one hand, because wave flume is general
It is long 10-20 meters, promote the raw wave machinery system loading of whole tank water miscarriage larger, it is difficult to long-play；On the other hand, seal
Close in tank and long-term to make wave wave can be caused constantly to reflect superposition so that waveform is at random, it is difficult to meet the preferable ripple for testing needs
Unrestrained condition.
For above-mentioned technical problem, with reference to above-mentioned principle, the present invention devises a kind of plant and is exposed to shallow-water wave ring for a long time
The analogue means in border, using the principle of relative motion, plant movement is driven by crank-link mechanism so that plant simulation is shallow
The motion of water particle in ripples, is simulated exposed to the state of shallow-water wave for a long time to plant, and then for plant physiology and biochemistry rings
The research of mechanism is answered to provide basis.

Reliability so that power can stably be transferred to draw bar 5 in same direction.It is bent when power source 6 drives crank 3 to rotate
One end that the drivening rod 4 of handle 3 is hinged with it rotates around it radius and moves in a circle, due to one end that connecting rod 4 and draw bar 5 are hinged
Limited in the motion of above-below direction, then when one end of connecting rod 4 moves in a circle, the other end of connecting rod 4 does in the horizontal direction
Straight reciprocating motion, and drive the draw bar 5 being hinged with it also to do straight reciprocating motion in the horizontal direction；Also, according to above-mentioned
Principle understands that the speed in the horizontal direction of draw bar 5 is in sinusoidal variations.At the same time, draw bar 5 with it being hinged with connecting rod 4
The relative one end in end constitutes non-articulated end, and plant cultivation box 2 is then only connected to the non-articulated end of draw bar 5, and plant cultivation box 2 with
Draw bar 5 is rigidly connected in the horizontal direction, and draw bar 5 can be driven with its rigidly connected plant cultivation box 2 in the horizontal direction
Straight reciprocating motion is done with the speed in sinusoidal variations, the water in water tank 1 remains static, then plant cultivation box 2 relative to
Hydrostatic in water tank 1 does straight reciprocating motion, and this motion actually simulates the motion of water particle in shallow-water wave, so as to simulate
Plant is for a long time exposed to the state of shallow-water wave environment.
Analogue means of the invention, the link assembly constituted using crank-connecting rod-draw bar drives plant cultivation box 2 to exist
Horizontal direction does straight reciprocating motion with the speed in sinusoidal variations, the motion of water particle in simulation shallow-water wave, and then to plant
State exposed to shallow-water wave is simulated；Compared with wave is made in push pedal in the prior art, required energy is driven to plant cultivation box 2
Amount is smaller, can persistently carry out Long-Term Simulations, and compared with wave is made in push pedal, and the motion of fairshaped plant cultivation box 2 is by water
Flow resistance power reduces to minimum, will not produce greater impact to the hydrostatic in water tank 1, and the water energy in water tank 1 enough keeps geo-stationary, no
The authenticity and reliability of simulation can be influenceed the problems such as the waveform caused by reflection is at random, can simulating plant for a long time exposed to shallow
Ripples environment, meets experiment demand.It can be seen that, the present invention breaches push pedal and makes unrestrained mode and can not for a long time provide preferable wave environment
