梯形彎折線單極子天線的諧振特性Xanthophyli cycle has been widely concerned since the finding that it has the function in heat dissipation. with the trans - thylakoid ph gradient, zeaxanthin ( z ) together with antheraxanthin ( a ) can absorb excess energy from chlorophyll and release it as heat, thus protect the photosynthetic apparatus from photodamage by high light. violaxathin de - epoxidase ( vde ) is the key enzyme in xanthophylls cycle
目前普遍認為葉黃素循環的色素定位於天線色素蛋白復合體上，在跨膜質子梯度（ ph ）形成后，玉米黃質（ z ）和環氧玉米黃質（ a ）能夠從葉綠素中吸收過多的激發能，並以熱能的形式耗散到體外，從而保護光合器官免受強光的破壞。Topics include : planets, planet formation ; stars, the sun, " normal " stars, star formation ; stellar evolution, supernovae, compact objects ( white dwarfs, neutron stars, and black holes ), plusars, binary x - ray sources ; star clusters, globular and open clusters ; interstellar medium, gas, dust, magnetic fields, cosmic rays ; distance ladder ; galaxies, normal and active galaxies, jets ; gravitational lensing ; large scaling structure ; newtonian cosmology, dynamical expansion and thermal history of the universe ; cosmic microwave background radiation ; big - bang nucleosynthesis
