查询词典 mean time

Mean operating time was 40 minutes (range, 30-90 minutes), and mean hospital stay was eight hours (range, 6-48 hours).

At six weeks after the procedure, patients had catheter removal and voiding cystourethrography, followed by urethroscopy one month later.

The article reviews the advanced research on screening sheepbreeds with high resistance against fasciolosis. Screening sheep breeds with high resistance against fasciolosis has been tested by measuring parameter of plasma such as packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin concen tration, glutamate dehydrogenase, gamma glutamyl transferase and aspartate trans ferase and percent take of metacercariae. High resistance of Indonesian thin tail sheep against Fasciola gigantica has been confirmed. The mechanism of high res istance and the time of killing Fasciola gigantica has also been described.

本文综述了抗片形吸虫病绵羊品种的研究概况，通过红细胞压积、红细胞平均体积、红细胞平均血红蛋白浓度、血清谷氨酸脱氢酶、γ谷氨酰胺转移酶、天冬氨酸转氨酶等血液学参数，囊蚴感染成活率的测定等方法来筛选抗片形吸虫病的绵羊品种，研究证明印度尼西亚细尾绵羊对大片吸虫感染具有较高的抵抗力，并概述了其抗虫感染的机制及杀虫作用时间。

该机构执行干事克洛德·芒迪作了预言性的预测。他表示，我们目前的道路&可能意味着价格的飞涨，或是更频繁的大面积停电；也可能意味着更多的电力供应中断，更多的气象灾害——或者，所有这些情况同时发生。&

Time to ischemic stroke and stroke in the same territory of the stenotic essel was compared in patients grouped by mean systolic blood pressure and mean diastolic blood pressure during the study.

进一步分析的是以病变的严重程度和狭窄的位置为根据。在试验过程中，把病人按照平均收缩压和平均舒张压进行分组，对比缺血性中风和狭窄血管相关区域的中风的时间。

Results Twenty four cases of retroperitoneoscopic ureterolithotomy were successfully done with mean operation time of 90 min and mean blood loss of 70 ml.

In 1 irrigation time and 2 irrigation times treatments, soil salt content decreased by 11.7%, and soil salt content increased by 12.6% in 3-4 irrigation times treatments. 2 After irrigation, the mean reduction of soil bulk density was 6.5%, and the mean increment of soil total porosity was 18.1%. With the irrigation frequency increasing, soil density was decreased and soil total porosity was increased. 3 Soil infiltration course of reed field irrigated by wastewater fitted Horton infiltration model well. After wastewater irrigation, the first infiltration rate decreased, but the stable infiltration rate promoted with the wastewater irrigation frequency increasing. 4 Soil water-holding capacity was increased by wastewater irrigation. The maximum water-holding capacity in capillary was 90.15 mm in the treatment of irrigation 3 irrigations, and the maximum water-holding capacity in non-capillary was 4.15 mm in treatment of 4 irrigations.

废水灌溉后，土壤pH均值降低6.0%；废水灌溉1～2次，土壤含盐率降低11.7%，废水灌溉3～4次后，增壤含盐率增加12.6%。2）废水灌溉后土壤体积质量均值减小6.5%，总孔隙度均值增大18.1%；随着废水灌溉次数的增多，土壤体积质量和总孔隙度分别有减小和增大的趋势。3）Horton模型比较适合描述废水灌溉后芦苇群落的土壤入渗过程，废水灌溉降低了初渗率，但随着废水灌溉次数的增多，稳渗率增加明显。4）废水灌溉增强了土壤贮蓄水分的能力，废水灌溉3次吸持贮水量达到最高（90.15 mm），灌水4次滞留贮水量达到最高（4.51 mm）。
