The driving wheel and front end beam was painted red color , and inside of operation room were painted ocher color . these are the standard painting color of the steam locomotives of china 涂装落车轮前端梁赤白涂分运?室内黄土色中国蒸?机?车标准的涂装
As there is no direct sailing from shanghai to your port during april / may , it is imperative for you to delete the clause “ by direct steamer ” and insert the wording “ partial shipment and transshipment are allowed ” 由于4 、 5月份没有从上海驶往你港的直达轮，请取消“用直达轮”条款，加上“允许分运和转船”字样。
3 . the cement produce enterprises should become the central of all aspects that we call it " the supply - chain " , make out and organize the implementation by the numbers range the cement in bulk produce . loading transit , uninstall storage to use 3 、水泥生产企业要有散装水泥物流观念和系统观念，要能担当供应链“核心企业”的领导作用，系统地规划，组织散装水泥从生产、装载、运输、卸载、仓储、分运与使用全过程的物流实施工作。
Water moves across the soil surface away from the drip emitter until the infiltration rate of the ponded area matches the emitter discharge rate . beyond this free - water pond water moves into the soil by unsaturated flow . it is very important to research the characteristic and pattern of trickle source infiltration 滴灌条件下水分运移的本质是微源入渗过程，因此，为了充分发挥滴灌优势，正确调控作物的土壤水分条件，对微源入渗特性规律的研究非常必要。
The effective factors of uniformity of subsurface drip irrigation was analyzed in this paper , and the manufacturing variation of simple orifices , rules of soil water movement and emitter discharge under subsurface drip irrigation , hydraulic characteristics and calculation of lateral in air were studied through experiment . the main results are as follows : ( 1 ) exactly drilling techniques can ensure lower emitter manufacturing variation . made simple orifices by electric drill obtained more uniform emitter discharge than by pricked , which is marginal 本文针对影响地下滴灌均匀度的因素分析入手，采用室内测定的试验方法，对简易地下滴灌灌水器制造偏差、土壤水分运移规律、灌水器出流规律以及空气介质中毛管的水力特性、水力计算等进行了研究，探索了保证一定灌水均匀度的灌水技术参数组合规律。
