| 1. | Study on stability of relative concentration ratios of cu , pb , zn in soil 锌相对浓度比稳定性的研究 |
| 2. | A positive research on equity concentration ratio and corporate performance of chinese agriculture listed companies 农业上市公司股权集中度与公司绩效的实证分析 |
| 3. | Actual operation shows that , using the stabilizer can secure the concentration ratio in the process and corrosion speed and meet the design requirements 现场实际运行结果表明,该水质稳定剂能保证该系统运动时的浓缩倍率及腐蚀速率满足设计要求。 |
| 4. | The concentration ratio has more influence on the profit rate than the scale . state - owned property rights has little side - effect on the profit rate , concentration ratio of industry is the result of efficient competition 而集中度比规模对利润率的影响更大;国有产权对利润率的负作用已经很小,行业集中度表现的是正常的效率竞争的结果。 |
| 5. | As for manipulation , the manipulator took on insider trading at the same time of manipulation . the stock tended to be manipulated with high concentration ratio of equity , few liquid equity and low turn - over ratio 以股本变动时期前后的日均换手率和日均收益率为样本,本文以logistic模型建立了适合我国国情的内幕交易和市场操纵判别体系。 |
| 6. | The plating measuring results were agreed well with the conclusion . thus , phosphorus generation mechanism of complex heterocatalysis was proposed . meanwhile , concentration ratio of niso _ 4 and nah _ 2po _ 2 also greatly affects the phosphorus content 同时研究发现,在络合体系相同的情况下,次亚磷酸盐和硫酸镍的浓度比对化学镀镍层中磷的含量有很大的影响。 |
| 7. | The influence of inflow velocity , the baffle body height and the clapboard position on the flow velocity , flow equilibrium between the two sides of the clapboard , particle distribution , rich / lean concentration ratio and flow resistance characteristic are studied numerically 文章研究了来流速度,撞击块高度、隔板位置等因素对气相速度场、隔板两侧配风均匀性、颗粒浓度、浓淡分离比和燃烧器内阻力特性的影响。 |
| 8. | 4 . because of input - output is inefficiency , which is limited by the low concentration ratio and expenditure situation , enterprise ' s technological innovation motivation is not enough . this leads to research and development expenditures is poor , the width and deepness of products development is not enough 受制于市场集中度不高和现有的消费状况,投入产出效率低,乳品企业技术创新的激励不足,造成企业研发经费投入和产品开发的深度、广度不足。 |
