| 1 | Survey on Pre-pregnancy Health Knowledge and Service Demands among Un-pregnant Married Women显示文摘Objective To understand the pre-pregnancy health knowledge and service needs among un-pregnant married women in Shanghai. Methods A total of 968 newly-married un-pregnant women in Changqiao, Lingyun sub-districts and Huajing town of Xuhui district, Shanghai, were recruited and inter- viewed by structured questionnaire to collect the information on pre-pregnancy health knowledge and service demands. Results 1) Newly-married women thought the contraceptive methods suitable for them was male condom(84.4%), followed by oral contraceptives(54%), emergent con- traceptive(52.5%) and contraceptive suppository (48.3%). 2) The score of pre-preg- nancy health knowledge was 54.7±14.5 among the subjects. The participants with junior college or a bachelor had more knowledge than those with junior or senior high school, and those who were engaged in medicine /education/science field had higher score. 3) They had higher knowing rate on the common knowledge, and the rate was above 80%. But the knowing rate on the knowledge of birth defect was low, and all below 50%. 4)A proportion of 52.7% of the respondents knew that there was a station for reproductive health service in their communities, but only 45.5% received the service from the station, 87.0% thought they had insufficient or scarce knowledge, 73.6% planned to consult before pregnancy and 63.6% were willing to attend the training courses on preparing pregnancy. Conclusion The participants had certain pre-pregnancy health knowledge, but still need being improved; in addition, they had higher needs on knowledge and service of birth defect prevention, at the same time they can’t make full use of the existing reproductive health institution. | Yu-hua LI Hong LIANG Li-feng ZHOU Ren-li WANB Er-sheng GAO Wen-ping SHEN Yue DONG Zhi-hui GU Rui-zhu CHEN Wei-jue CAO Guo-liang ZHOU Xiao-ping ZHOU | 2006 | Journal of Reproduction and Contraception2006，17，3： | 0 |
| 2 | Effect of Al Layer on Oxidation Behavior of NbCrAl Coating显示文摘NbCrAl coatings in the presence or absence of Al outer layer were prepared on C103 Nb based alloy and alumina substrate by direct current magnetron sputtering technique. The oxidation performance of coating systems was evaluated by isothermal oxidation tests. The element diffusion and oxidation behavior of the coating systems were investigated. The results indicate that the mass gains of NbCrAl and Al/NbCrAl coatings are 2.02 mg/cm^2 and 0.79 mg/cm^2 at 1 000 ℃ for short time. Al/NbCrAl coatings exhibit more effective protection than NbCrAl coatings. The addition of Al layer can improve the oxidation resistance of NbCrAl coatings, which is attributed to the Al layer offering enough Al content to react with oxygen to form a continuous and dense Al_2O_3 scale on NbCrAl coating and it can inhibit the further internal oxidation. | 许安 CHEN Quanzhi HUANG Zujiang DONG Wanbing 李伟洲 | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，2： | 0 |
