藏精是腎的主要生理功能，腎中精氣，是機體生命活動之本，對機體各方面的生理活動均起著極其重要的作用；腎主水液，主要是指腎中精氣的氣化功能，對于體內津液的輸布和排泄，維持體內津液代謝的平衡，起著極為重要的調節作用；腎主骨生髓，實際上是腎中精氣具有促進機體生長發育功能的一個重要組成部分，腎中精氣的盛衰，不僅影響骨的生長和發育，而且也影響脊髓和腦髓的充盈和發育； 「齒為骨之餘」 ，齒與骨同出一源，牙齒也由腎中精氣所充養，腎中精氣充沛，則牙齒堅固而不易脫落，若腎中精氣不足，則牙齒易於松動，甚至早期脫落；腎開竅於二陰（外生殖器和肛門） ，因此，尿頻、遺尿、尿失禁、尿少或尿閉，均與腎的氣化功能失常有關。In the course of working, ， the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right. compared to the unilateral plow, it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey. to meet the requests above, we will use a remote cylinder with both a small cubage and double functions, approximately designing the plow to be columniform and symmetric. after the experiment for a period in the field, we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly
