Half a dozen cylindrical roots will branch off this stem, and the plastic will flow throughthese from the reservoir to the tip.
主干上分出六条柱状根,液态塑料从储液囊中流过这些柱状根,直至其顶端。
As in a real root, the tip will be a specialised structure.
和真的根一样,柱状根的顶端是一种特别的结构。
Instead of being a cone containing a meristem it will be a cone containing a motor, alight-emitting diode and a battery.
两者都是圆锥结构,不过前者里面有一个分生组织,而后者里面是电机,发光二极管和电池各一个。
The motor will suck liquid plastic through the root and push it to the periphery of the cone.
电机将液态塑料吸入根部再将之推至圆锥体表层。
Once there, the liquid will be solidified by ultraviolet rays from the diode, extending thecylinder and forcing the cone farther into the soil.
液态塑料到达该位置后马上会因二极管发出的紫外线照射凝固,使圆柱体增长,促使锥体在土壤中更进一步。
As in real life, the gentle but relentless pressure of the root s growth should be enough tomake it advance through the soil, fractions of a millimetre at a time.
对真正的根来说,由根部生长带来的和缓但从不间断的压力足以使之在土壤中前进,一次能前进几丝米。
