filling by weight
解釋
按重量裝填-
Results showed that by using straw and plastic film dual mulch in dry - cultivation of rice planting, both of the range of temperature difference and the loss of water in dry - cultivated field of rice were decreased, the soil structure was improved, the soil nutrient contents were increased, the ineffective tillers of rice plant were decreased, the growth and development stage were advanced, the filling stage was extended, the grain per ear and 1 000 grain weight were raised, the grain yield of rice increased obviously
水稻秸稈+地膜二元覆蓋旱作栽培效應的研究結果表明，秸稈+地膜二元覆蓋旱作稻田土壤變溫幅度降低，水分散失減少，結構改善，養分積累增加；水稻無效分蘗減少，生育轉變提前，灌漿結實期延長，穗大粒多，千粒重高，增產效果顯著。 -
Testing of packaging ; determining the filling ratio of standard capacity prepacks ; prepacks whose contents are indicated by weight

In this paper, ptfe and ptfe composited with sicp, sicw, mos2p and sicp + mos2p with various ratios respectively have been obtained by compression molding. under the condition of dry friction, a systematic study has been done on the weight loss and the friction coefficient of composites and the relations between the properties and content of the filling, the load and the sliding velocity
在干摩擦滑動磨損條件下，對ptfe材料及其復合材料的磨損失重、摩擦系數及磨損機理進行了研究，同時對其與磨損外部條件（載荷、滑動速度）和材料的內部因素（填料的含量、粒徑、種類）的關系進行了較為系統的研究。 -
As for uhmwpe - base composites reinforced by cu powder, the one whose filling cu powder makes up 15 % of the composite by weight has lower friction coefficient and smaller wear value than the others
填料cu粉質量分數為15時的復合材料摩擦系數較小，磨損量較低；填料cuo質量分數為10 15時復合材料的摩擦磨損性能較好。
