求翻译：综上所述，通过对齿轮的优化设计大大减轻了齿轮的质量(或体积)，不仅使月球车轮腿结构更加紧凑、重量更轻，而且节约了材料、降低了成本，从而为优化月球车的轮腿机构提供了一种有效的方法和途径。是什么意思？

In summary, through the optimization of gear gear design greatly reduces the quality (or volume), not only the moon wheel leg structure is more compact, lighter weight, and material savings, reduced costs, so as to optimize the lunar rover round leg mechanism provides an effective method and means.

In summary, the gears through the optimization and design has considerably reduced the gear in the quality (or volume) will not only make the moon wheel and better structured, lighter in weight, but saving materials, reduced cost and thus for the optimization of the moon car round the body and provi

In summary, reduced the gear quality greatly through the counter gear optimized design (or volume), not only causes the Moon wheel leg structure to be more compact, the weight is lighter, moreover saved the material, reduced the cost, thus for optimized the lunar jeep the wheel leg organization to p

To sum up, through the optimization of gear design greatly reduces the quality of gear (or volume), not only make the Lunar wheel leg of a more compact, lighter weight, and saving materials, reduced costs, so as to optimize the Lunar Rover wheel leg mechanism provides an effective ways and means.

In summary, through the optimization of gear gear design greatly reduces the quality (or volume), not only the moon wheel leg structure is more compact, lighter weight, and material savings, reduced costs, so as to optimize the lunar rover round leg mechanism provides an effective method and means.
