preform信息详情
v.预先形成
n.粗加工的成品
Preform, its manufacturing method, and container produced by biaxially stretching the preform.───坯，其生产方法，和从该料坯制造的双轴拉伸容器。
Otherwise, he will never be able to preform again.───否则，他不会是能的再预先形成。
This preform is then heated to a temperature just below the melting point of the alloy.───此时，将初步加工的成品加热到一定的温度，这个温度要刚刚低于合金的熔点。
A cooling circuit for a neck ring of a preform is conformed to the surface of the neck ring by providing a neck ring in two parts.───本发明提供一种用于一预成型件的一颈环的冷却回路，其通过以两部分提供一颈环来与所述颈环的表面相配。
The preform is formed by an upper neck which maintains unchanged its form in the final object and a hollow body, joined to the neck.───预型件成形为具有保持其形状在成品中不变的上颈部和连接到该颈部的中空体。
The preform growth during the stretching and blowing was captured through a transparent mold and used to verify the simulation results.───研制了全透明拉伸吹塑模具，通过可视化实验对模拟结果进行验证。
And preschool-age children are easy to preform altruistic behavior to their teachers.───学前儿童对不同对象的利他选择存在差异，幼儿更易于对教师作出利他选择。
The Bakelite resin could be compression molded from a loose powder or compressed into a preform, then molded.───胶木（即酚醛树脂）可从松散的粉末压缩模塑或先压缩预制成型，然后模塑。
A holey fiber can be produced by drawing the holey porous preform, after having submitted it to a consolidation process.───可通过将多孔疏松预制棒送入固结工序之后拉丝该多孔疏松预制棒而制造多孔光纤。
Condensate will leave marks on the preform surface.
The exterior walls were made of pre-formed concrete.
The preform preferably has a D/d ratio of about 15 or more, and an optical fiber may be drawn directly from the preform.
Is everything preformed from the beginning, or is development more like the knitting of a fisherman's net?
The structure of preform is described, the processing parameters are predicted in theory and the designs of functional and structural composites are provided by the method of topological analysis.
It does not itself contain a preformed structure, but simply opens up possibilities.
The optimization procedure of preform die shape is given. The sensitivity of nodal velocity and temperature with respect to design variable is developed.
Major in PET preform mould, cap mould and blow mould.
To what extent is the pattern already preformed?
