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
與單向犁相比，其優點在於：耕地無開、閉壟，地表平整，降低了耕后整地的能量消耗，減少了地頭的空行程，因而大大提高班次生產率。為了滿足犁體梭式作業的要求，我們採用了一隻小容積雙作用的液壓油缸；同時對犁壁曲面的形狀採用了近似圓柱形的對稱設計。但經過一段時間的田間試驗，我們發現：該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴重；主犁梁和油缸缸體的連接部分（即油缸底座）突然發生了斷裂，造成整個犁體無法正常工作。The main components of the latter are multi - rib sandwich panels, including floor slabs and wall slabs. reinforced concrete conformation columns are set where the longitudinal walls and latitudinal walls intersect and copulative beams are set where floor slabs and wall slabs intersect. they play a role of linking and transferring loads, bearing a small part of loads at the same time

前段時間，教育部門組織體育教師對中小學實施新課標改革情況進行調查，調查表明，一些學校由於辦學規模小，特別是一些農村小學，沒有運動場地，或者對體育鍛煉不夠重視等等，沒有很好地按照新課改要求開足體育課，由於升學制度的制約，一些學校無視學生體育活動和身體健康，有些高年級的體育課貫用「偷梁換柱」的做法，外排體育課，內上文化課，目前多數中小學體育場地布局、器材設施陳舊、緊缺，根本無法保證學校正常的體育活動的開展，更難以說適應新課材的要求。However, it is impossible for astronomers to see the even horizon directly due to the current technical limitation. therefore what scientists discovered so far is only an indirect evidence of the gravitational redshift or similar phenomenon caused by black holes. but those results undoubtedly become an important bridge for linking black hole theory with actual observation
