預壓制粒 的英文怎麼說
中文拼音 [yùyāzhìlì]
預壓制粒
英文
preliminary compression granulation-
There are many defects in the tic preforms prepared by cold pressing, such as small air holes and cracks. the tic preforms prepared by hot pressing have better qualities
冷壓成型預制體一般存在分層、裂紋等缺陷，未造粒的粉體壓制時流動性、均勻性差是根本原因。Si particles porous preforms were prepared by cold isostatic pressing process ( cip ). its average porosity is about 31. 3 %. 3
採用冷等靜壓方法制備出si顆粒多孔預制體，平均孔隙率為31 . 3 。Therefore it is necessary to study the contribution of hadron environment to the suppression. many works have studied j / suppression in hadron environment with glauber model. but the combination of nucleus absorption and comover mechanism in hadron environment can not explain the abnormal suppression of j / production in pb - pb collision yet
但是強子環境中的核吸收和同行粒子對j w的相互作用機制結合起來仍不能解釋pbpb碰撞過程中j w的反常壓低，也就是說需要引入新的機制，這可能預示著夸克一膠子等離子體的形成。The dried powder raw materials will be fed from the top of dry granulator, then enters into flaking machine where becomes flakiness raw material will be made into the needed granule product through the procedures of crushing, processing granule and sieving powder and so on
乾燥后的各種乾粉物料從干法制粒機的頂部進入，經預壓進入軋片機內，在軋片機的雙輥擠壓下；物料變成了片狀、片狀物料經過破碎、整粒、篩粉等過程，得到需要的粒狀產品。The multilayer composite including a hard component tz - 3y20a and a plastic soft component mo has been fabricated by particle sedimentation method. by choosing appropriate settling parameters and dispersed medium, the tz - 3y20a / mo multilayer composite has been obtained via alternating deposition of tz - 3y20a and mo according to the design of individual layer thickness and layer thickness " ratio
採用顆粒沉降成型工藝，選用適當的沉降參數與分散介質，將tz - 3y20a陶瓷粉和mo金屬粉按設計的層厚和層數進行交互沉降，得到預成型體，再經1500 ? 20mpa ? 1h熱壓燒結，制備出緻密的tz - 3y20a mo疊層材料。分享友人
