The Inventory for Chinese LFC in 2006

1. Introduction Lost Foam Casting has been introduced into China for two decades, and it is getting more popularity in foundry industry.In China there are two associations responsible for the LFC industry and academic exchanges: Chinese Lost Foam Casting Society (CLFCS) and Chinese Association of Full Mold Casting.     

THERMODYNAMICS OF BAINITIC TRANSFORMATION IN Cu-24 at.-% Al ALLOY

Two driving forces △G~((β_1)+α')and △G~(β_1→β_2+α)for the bainitic transformation have been calcu-lated for Cu-24 at.-% Al alloy.Results reveal △G~(β_1→α')>0 within the transformation tem-perature range 600—750 K.Therefore,the bainitic transformation cannot be initiated by theβ_1→α' shearing mechanism.On the other hand,the driving force △G~(β_1→β_2+α)to produce 5% ofthe α becomes negative only when the composition of the α satisfiesx_(Al)~α≤0.204 at 700 K or x_(Al)~α=0.209 at 750 K.So the bainitic transformation can only proceedby β_1→β_2+α diffusional reaction with different diffusion amount at different temperatures.

A combo technology of autotrophic and heterotrophic denitrification processes for groundwater treatment

In this study,a sequential process (heterotrophic up-flow column and completely mixed membrane bioreactors) was proposed combining advantages of the both processes.The system was operated for 249 days with simulated and real groundwater for nitrate removal at concentrations varying from 25 to 145 mg·L-1 NO3-N.The contribution of heterotrophic process to total nitrate removal in the system was controlled by dozing the ethanol considering the nitrate concentration.By this way,sulfur based autotrophic denitrification rate was decreased and the effluent sulfate concentrations were controlled.The alkalinity requirement in the autotrophic process was produced in the heterotrophic reactor,and the system was operated without alkalinity supplementation.Throughout the study,the chemical oxygen demand in the heterotrophic reactor effluent was (23.7 ± 22) mg·L-1 and it was further decreased to(7.5 ± 7.2) mg·L-1 in the system effluent,corresponding to a 70％ reduction.In the last period of the study,the real groundwater containing 145 mg·L-1 NO3-N was completely removed.Membrane was operated without chemical washing in the first 114 days.Between days 115-249 weekly chemical washing was required.     

电子阅读器“彩色墨水屏”时代来临——文石BOOX Nova3 color

和十几年前的第一款电子书阅读器时不同,现在的电子书阅读器发展的已经十分完善。在阅读体验上高分辨率的墨水屏能带来比纸张更细腻的阅读体验。在书籍资源上,电子书也有纸质书无法比拟的优势,基本上现在想要的任何书籍都能在网上找到或者在电子书城买到。在便携性方面,电子书也是碾压纸质书的。但一直以来,电子阅读器都只有黑白墨水屏,而如今,电子阅读器终于迎来了彩色墨水屏——文石BOOX Nova3 color。     

Research and Applications of Semi-solid Processing

Since it was pioneered by Flemings and otherresearchers [11, the semi-solid metal processingtechnique has been widely stUdied in the world.Especially in the past decade, SSM as a newproduct forming technique has been rapidly developed and put into commercial applications[2, 31. In recent years, with the development ofthe ado-industry of China, a lot of researchwork on SSM has been done, including the preparation of slumes, reheating and thixoforming[Al6]; moreover, great achievements have …
