Abstract: Fulgide is well-known as a thermally irreversible organic photochromic compound.
Diaphragm D1 is placed in the spatial frequency spectrum plane of the 4f system composed of L3 andL4, which is used to filter high-order diffractive waves, so on the back focal plane of L4 the object image without grid structure to be recorded can be got.

Light energy absorbed by chlorophyll molecules in a leaf can undergo one of three fates: it can be used to drive photosynthesis (photo-chemistry or photochemical quenching, qP), excess energy can be dissipated as heat (heat dissipation or non-photochemical quenching, NPQ) or it can be re-emitted as light—chlorophyll fluorescence.
Hence, physiological adjustments, time allow and of possible, like subtle modifications to the structure of photosystems or the gas exchange systems are necessary for the imported Aesculus grow well in a distinct climatic region.
