| 1. | Study on test methods for soil available s and critical levels of s deficiency 土壤有效硫评价方法和临界指标的研究 |
| 2. | When the fuel reaches a critical level , a message will appear on the screen 当燃料达到危险水平,一条信息将会出现在屏幕上。 |
| 3. | Currently the atl mfc sources use a trace level of 04 , where 0 is the most critical level 目前, atl / mfc源使用的跟踪级别分为04级,其中0是最关键的级别。 |
| 4. | Then the author presents us three levels of reading , i . e . literal level , interpretive level and critical level 同时分析了三个层面上的阅读:表层意思的阅读,深层意义的阅读和评价性阅读。 |
| 5. | If field applied for general plumbing applications , the critical level of the 289 shall be 6 " ( 152mm ) above the flood rim 如果现场应用在常见的管道应用上,则289的临界面应该位于高出地面152毫米的地方。 |
| 6. | When factory installed deck / machine mounted on machines or equipment , the critical level of the 289 shall be 1 " ( 25mm ) above the flood rim 当工厂安装在台面上,或机械安装在机械或设备上, 289的临界面应该在地面上25毫米处。 |
| 7. | Because of the evaporation , dissolved salt is brought to cumulate at the ground surface and the root zone when the ground water is above the critical level . then the saline soil is formed 超过临界深度的地下水,在蒸发作用下,将盐分带至地表或根系分布层累积下来,形成盐渍化土壤或盐土、碱土。 |
| 8. | Objective : to provide a minimum sample size approach and a sequential sampling approach for testing whether the sporozoite rate has exceeded the critical level of malaria epidemics using the pool sampling method 摘要目的:给出基于混合样本的最小检测次数法和序贯检验法,以检验子孢子阳性率是否超过导致疟疾流行的临界水平。 |
| 9. | Although the available content of p in the soil was above the critical level , it showed deficiency in the greenhouse experiment , probably because of the strong adsorption by the soil , and the high requirement of the sorghum plants to p from the small volume of soil 尽管磷在土壤中的有效含量高于亏缺临界值,在温室试验中却表现出缺乏,很可能是由于土壤对磷的吸附很强,同时盆栽土壤体积小,高粱吸收磷强度大。 |
| 10. | Some soil microbial activity parameters and heavy metals contents were analyzed by principal component method . the results showed that the critical levels of cadmium and lead in red clayed soil and red sandy soil were 15 mg . kg - 1 and 0 - 15 . mg . kg - 1 , 200 mg . kg - 1and 200 - 400 mg . kg - 1 , respectively . soil microbial populations and functional diversities of microbial community have changed to some extent under the stress of cadmium and lead pollution 在本文中我们将供试红壤的上述微生物活性指标和2种重金属含量进行主成分因子分析,其结果得出,红黄泥和红砂泥的土壤微生物活性镉胁迫的临界承载量分别为15mg ? kg ~ 1和0 15 ? mg ? kg ~ 1 ;铅胁迫的临界承载量分别为200mg ? kg ~ ( - 1 )和200 400mg ? kg ~ ( - 1 ) 。 |
