查询词典 ratios

Earlier this year, William Lassek, an epidemiologist at the University of Pittsburgh in Pennsylvania, and anthropologist Steven Gaulin of the University of California, Santa Barbara, reported that women who accumulated more fat on their hips than on their waists--and who, therefore, had low waist-hip ratios like many movie stars--had higher cognitive test scores, as did their children.

今年年初，宾夕法尼亚洲匹兹堡大学流行病学家William Lassek以及圣芭芭拉加利福尼亚大学的人类学家Steven Gaulin报道说，那些臀部脂肪蓄积大于腰部—亦即类似于影星的低腰臀比身材—的女性，在认知能力测试中得分较高，而她们的子女也是如此。

The energy loss through feces was 0.077C (C: food consumption, KJ/d) and the energy loss through excretion was 0.052C at maximum feeding rate. In that the ratios of F and U to C were low in fish energy budget equation (Cui et al., 1997), the energy loss through feces at optimum feeding rate could be estimated by 0.077C〓(C〓: the optimum feeding rate) and the energy loss through excretion at optimum feeding rate could be estimated by 0.052C〓. The relationship between total energy content for immature gibel carp and body weight was lnE=1. 476+1. 127lnW.

最大摄食率条件下，异育银鲫排粪能损失：F=0.077C，排泄能损失：U=0.052C；由于排粪能及排泄能在能量收支方程中所占比例不大（崔奕波等，1997），最适摄食率条件下的排粪能损失可估计为F〓=0.077C〓（C〓：最适摄食能，KJ/d），排泄能损失可估计为U〓=0.052C〓；性未成熟异育银鲫的能量含量与体重的关系为：lnE=1.476+1.127lnW

Road pricing allows you to very precisely evaluate the benefits of new roads," says Stephen Glaister, an adviser to Sir Rod from London's Imperial College."Some of these schemes have benefit-to-cost ratios of ten to one or better.

公路收费能让你很精确地估算修建新路的收益，&Rod爵士的顾问、来自伦敦皇家学院的Stephen Glaister说，&一些计划的收益与成本比是10比1，甚至更好。

But after 30 days or more long, the effective ratios of the three groups decreased at a different rate. Three months later, there was a significant difference between lased-with-CaF2 group and Gluma group on effective rati

MAIN OUTCOME MEASURES:①degradation rates of PLGA with different ratios of lactic acid and glycolic acid.

主要观察指标：①不同质量比聚乳酸-乙醇酸的降解速率。

Part I: Characterization of the stability and biocompatibility of PLGA conduits.1 Artificial nerve conduits were successfully fabricated using two different copolymer ratios of PLGA(85:15 and 50:50)(lactide:glycolide).2 Degradation of PLGA(85:15) and PLGA(50:50) conduits were examined in vitro for 12 weeks in phosphate buffered saline at 37℃, pH 7.4 and in vivo for up to 8 weeks following implantation into the rat dorsal muscle.

结果显示：①体内外降解条件下，PLGA(50：50)管吸水率、失重率及生物降解率显著高于PLGA(85：15)管；②两种材料样品体内生物降解率显著高于体外降解率；③扫描电镜观察显示，随降解时间延长，材料样品表现为特征性的虫蚀样破坏并进行性加重，以PLGA（50：50）管尤为明显。

Different plant hormones and their different concentration ratios have different effects on the callus of Halenia elliptica D.

结论不同培养条件对椭圆叶花锚愈伤组织的诱导有不同的影响，其中以无菌苗的茎段为外殖体易形成愈伤组织。

Don.methodswith the stem of sterile seedling and fresh plants as exophyte, ms as a basic medium, 6-ba and naa hormone were adopted as the experimental variables.resultsms +1.0 mg / l 6-ba +1.0 mg / l naa induced the best effect of callus; higher concentrations of 6-ba with high concentrations of naa made callus densification and higher rate.conclusion different plant hormones and their different concentration ratios have different effects on the callus of halenia elliptica d.

方法以椭圆叶花锚种子培养的无菌苗的茎和新鲜植株的茎段为外殖体，ms为基本培养基，分别以6-ba和naa两种植物激素为变量进行实验研究。结果ms培养基+1.0 mg/l 6-ba+1.0 mg/l naa对诱导椭圆叶花锚愈伤组织的形成效果最佳；高浓度的6-ba配合较高浓度的naa诱导的愈伤组织致密，出愈率高。

The number of CD〓 and CD〓 lymphocytes subpopulation and IgA, IgM, IgG antibody-producing cells, the ratios of CD〓 and CD〓 T-cell in the cecal tonsils and Harderian glands, the content of IgA, IgM, IgG in tear, tracheal fluid, intestinal fluid and bile of CIAV-infected chicks vaccinated with ND vaccine were significantly decreased compared with vaccinated control chicks 7～28 days PV.
