| 1 | A simple way to make pre-stressed ceramics with high strength显示文摘A pre-stressing design and a simple fabrication technology to substantially improve the strength of ceramic components are presented.Residual surface compressive stress is generated in ceramic components by pressureless sintering of a green bulk coated with a thin layer of low coefficient of thermal expansion(CTE).The stress level can be controlled by changing the cross-section area ratio,Young's modulus ratio and CTE ratio of the coating.Pre-stressed ZrO_(2) ceramics coated with Al_(2)O_(3) can achieve a flexural strength of 1330±52MPa,45% higher than their uncoated counterpart.Similarly,the flexural strength of building porcelain tiles is increased by 70%,from 67±3 MPa to 114±5MPa.The damage tolerance of pre-stressed ZrO_(2) ceramics is excellent with a high residual strength of ~1200 MPa in a thermal shock test at 325℃.This simple technique can improve the mechanical performance of ceramic components with no limitation of size and shape. | Yiwang Bao Fenghua Kuang Yi Sun Yueming Li Detian Wan Zongyang Shen Delong Ma Lingfeng He | 2019 | Journal of Materiomics2019，5，4： | 7 |
| 2 | Determining the biological zero for gonadal development razor clams Sinonovacula constricta (lamarck 1818) in Zhejiang,China显示文摘The biological zero of gonadal development and the effective accumulated temperature of one and two-year-old razor clams Sinonovacula constricta(Lamarck 1818)were studied in Sanmen County,Zhejiang Province,China between April 2016 to October 2017,using a new variety named“Shen-Zhe No.1”.The biological zero was determined by using the rule of effective accumulated temperature and the linear regression method,which was confirmed using a histological analysis of the full gonadal development cycle.The results showed that the biological zero of gonadal reproduction of 1-year-old and 2-year-old S.constricta was the same:20.8℃.When the temperature reached 20–21℃,analysis of the histological sections indicated that more than half of the S.constricta individuals initiated gonadal development.The average effective accumulated temperature over two years was 806 d℃.This study contributes to our understanding of the regulation and control of gonadal maturation,suggesting that changes in the spawning and breeding season during one-year of farming using the new variety of razor clam could provide an economic benefit to industrialized large-scale spat production.The results demonstrated that the razor clam S.constricta is a typical clam of the accumulative temperature mature oviposition type.In addition,although S.constricta does not display hypothermy,it requires a lower temperature for gonadal maturity and spawning. | Baobao Xue Delong Meng Hao Li Wei Liang Donghong Niu Jiale Li Heding Shen | 2021 | Aquaculture and Fisheries2021，6，1： | 1 |
