However , cpt of simple visual reactions ( cpt ( svr ) ) and the cpt of recognition visual reactions ( cpt ( rvr ) ) were significantly prolonged in patients 然而，病例组的简单视反应的认知加工时间和认知视反应时的认知加工时间显著延长。
The model is tested by a typical die - cavity roughing , and shortening machining time and balancing cutting - load can be attained 通过典型模具型腔的粗加工试验验证，证明该进给率优化策略不仅可以缩短加工时间，而且可以使加工载荷均匀。
2 . polynomial - time approximation schemes ( ptas ) lemma 1 with 1 + cost , we can assume that all processing times and release dates are integer times of 1 + 引理1在修正费用不超过1 。的情况下，可以将原实例的加工时间和到达时间修改为1 。的整数次幂
We provide an algorithm for the special case in which the jobs have two release times and prove that its worst case ratio is not more than 33 / 14 就所有工件有两个到达时间的且工件加工时间与尺寸大小一致的排序给出算法，并证明了算法的性能比不超过33 / 14 。
Multi discs : multi - disc ring disc is consisted of precision flange and partition to promote cutting efficiency , shorten molding time for cutting and reduce molding cost 多片式：可用精密的法兰隔片组成多片式环型切片，提高切割效率缩短切割加工时间降低加工成本。
The solutions shows that the results of the problems with constant processing times also hold in the case where the processing time of a job is a linear function of its starting time 结果表明，加工时间为常数情况的结论对于加工时间是开工时间线性函数的情况仍然成立。
By normalizing all job sizes and machine cost , we assume that the cost of purchasing one machine is 1 . we further know the total size of all jobs in advance 通过标准化所有工件长度和机器费用，我们可假设购买一台机器的费用是1 .所讨论的半在线模型假设已知所有工件的总加工时间
In this paper , we address the single machine scheduling problem with discretely controllable processing times , our objective is to minimize the makespan plus the total processing cost 摘要考虑工件加工时间离散可控的单机分批排序问题，目标函数是极小化最大完工时间与加工费用之和。
It is possible to view all the jobs in the same batch as a single aggregate job , with a process time which is equal to the processing time of the longest job in the batch 当工件被分批加工时，每一批的工时为该批中所有工件的加工时间的最大值，到达时间是其中的工件最晚的到达时间
Comparing with the existing rapid spray tooling technolog4 , the proposed technique not only shortens the technical flow and reduces the process time , but also improves the mould dimension precision 与现有的熔射快速制模工艺相比，该工艺不仅缩短了工艺流程和加工时间，还提高了制模精度。
