As the shaped blank and the paper mould are sintered together, the number of waste products caused by dry crack is reduced and the yield rate is raised. 由于成型后的毛坯与纸制模具一起烧成,减少了因为干燥裂纹而形成废品的数量,提高了成品率。
In testing the water quality, we verify the accuracy and the precision of the methods in various aspects such as blank value assay, recovery rate experiment and parallel determination experiment. 在水质化验室的工作中,采用测定程序空白值、加标回收、平行测定等质量控制手段,从不同方面来验证方法的准确度和精密度。
The turbine body is cast blank, which complicated shape and high accuracy rate bring certain difficulty for machining. 蜗轮壳体为铸造毛坯,形状复杂,加工精度高,给机加工带来了一定的难度。
The determination of the tin content of the atmosphere by Graphite Furnace Atomic Absorption Spectrophotometry is introduced. We have carried out several experiments, including the measurement of the whole procedure blank test, the determination of the precision, the accuracy and the recovery rate test. 介绍了用石墨炉原子吸收分光光度法测定大气颗粒物中的锡,并进行了全程序空白值的测定、精密度测定、准确度测定,以及加标回收率实验。
This paper described some advantages of plasma spray process, include components of powder, spraying principle, machining parameters of blank, parameter control of spraying process, effects of blowhole rate and metallography of coating. 介绍了活塞环加工过程中等离子喷涂工艺的优点,详细阐述了喷涂粉末的配比、喷涂原理、毛胚的加工参数、喷涂工艺参数的控制,以及气孔率、涂层金相的影响。
The catalysts could be repeatedly used for several times. Compared with the blank experiment results, the catalysts FSZ greatly increased the dechlorination rate and the final dechlorination ratio of waste PVC, and decreased the dechlorination temperature. 与空白实验相比,FSZ(固)催化剂明显提高了废旧PVC的脱氯速率和最终脱氯率,降低了脱氯温度。
A suitable blank shape can improve stamping properties, rate of fin-ished products, materials utilization ratio economical efficiency. 确定毛坯合理外形,能改善冲压性能,提高零件生产的成品率和材料利用率,从而提高经济效益。
The results show that: the forming result of the first blank is bad, while the second blank can wok well, and the max thinning rate is 16.6%. 研究结果表明:方式1是不可取的,而方式2能很好地成形出合格零件,最大减薄率为16.6%,最大增厚率为1.84%。在法兰处可以适当添加拉延筋以缓解起皱趋势。
Results Blank control can monitor polluting positive reaction well and BCG of different rate of dilution not only detect sensitivity of reagents, but control quality of whole experiment. 结果空白对照能很好地监测污染造成的假阳性,以不同稀释倍数的BCG不但能很好地检测试剂的敏感度,且能对整个实验加以质控。
Results ① The inhibitory rate was 68.32% in the curcumine group, 70.43% in the positive controlled group. Compared to blank control group, these two groups had significantly elevated tumor inhibition rate ( P0.01). 结果①姜黄素组的抑瘤率为68.32%,阳性对照组的抑瘤率为70.43%,与空白对照组比较,两组的抑瘤率均明显升高(P0.01)。
For shape of CC beam blank is complex, there are more rate of longitudinal crack on the surface. 连铸异型坯由于其形状复杂,表面纵裂纹发生率较高。
Through the experiment, the conclusions are as follows: 1, After soybean harvest, soil nutrient content under sewage treatments were higher than the blank ( no fertilizer treatment A), and slightly increased with increasing sludge application rate, soil pH was the opposite. 通过试验,得出如下结论:1.大豆收获后,各施污处理的土壤养分含量均高于空白(不施肥处理A),且随着污泥施用量的增加而略有增加,而土壤pH则相反。
The trends of retention factors of imprinted and blank MTC synthesized under different conditions were investigated. Furthermore, effects of methanol content, pH and flow rate on the separation performance of MIMC were discussed. 考察了模板分子在不同条件下合成的印迹整体柱及空白整体柱上容量因子的变化规律,同时探讨了流动相中甲醇的含量、pH值、流速对印迹整体柱分离性能的影响。
