"The third planet from the sun, having a sidereal period of revolution about the sun of 365.26 days at a mean distance of approximately 149 million kilometers (92.96 million miles), an axial rotation period of 23 hours 56.07 minutes, an average radius of 6,374 kilometers (3,959 miles), and a mass of approximately 29.11 10 kilogram s (13.17 10 pounds)."

"离太阳第三远的行星，绕太阳转动的恒星周期为365.26天，平均距离大约是1.49亿平方公里(9，296万英里)，自转一周的周期为23小时56.07分，平均半径为6，374公里(3，959英里)，质量大约是29.11×10千克(13.17×10英镑)。"

The central integrative part of the baroreflex receives afferent information not only from the sino-aortic baroreceptors, but also from various other sources. The present study was to investigate the effect of somatic nerve stimulation on baro-reflex. The exoeriment was performed in α-chloralose-urethane anesthetized rabbits. Intrasi- nusal pressure -mean arterial pressure res- ponse curves were constructed.

在自然状态下，各种传入冲动汇集中枢，很多传入冲动都可影响压力感受性反射，使压力感受性反射受到调制而发生重新调定·本实验旨在观察刺激躯体神经对压力感受性反射的重调定并分析其机制·实验在α-氯醛糖和氨基甲酸乙酯混合麻醉的家兔上进行，利用颈动脉窦灌流技术测量不同窦内压时体循环平均动脉压的水平，并画出窦内压-体循环平均动脉压反应曲线。

The experiment result shows that, as far as the environment temperature decreases -5℃, starting resistance torque increases 2.5 N·m; starting resistance torque increases 3-8 N·m when the rotating speed increases 50 r/min.

通过ISAD柴油机起动台架试验可以看出：相同的环境温度下，起动阻力矩随起动转速的提高而增大，每提高50 r/min，每缸平均起动阻力矩增加3～8 N·m；起动阻力矩随环境温度的下降而增加，0℃以下时，每降低5℃，平均每缸起动阻力矩增加2.5 N·m。

The DNA data analysis showed that the average intra-species genetic distance was 0-0.005; there was no significant genetic divergence between the western flower thrips found in Beijing in 2003 and those reported internationally.

分子数据分析显示：种内个体间平均遗传距离在0~0.005之间，2003年在北京发现的西花蓟马与欧洲等地区报导的西花蓟马不存在明显的遗传差异；9种蓟马种间平均遗传距离为0.213。

Tree ring width of diseased trees decreased 12.77% than that of healthy trees.

受害材的平均年轮宽度为 1 0 。42 mm，健康材的平均年轮宽度为 1 1 。83mm，受害材较健康材相对下降 1 2 。77%，方差分析表明受害材与健康材的年轮宽度有显著差异。

Countries with taller women have higher rates of twinning compared to countries with shorter women.

与女性平均身高较低的国家相比，在女性平均身高较高的国家孪生的发生率也较高。

In a probabilistic analysis of unrepairable systems, system behavior is described by reliability and mean time to failure, in which the reliability is defined by the probability of the random event "system is functioning at time t", and MTTF the expected value of random lifetime of system.

衡量不可修系统可靠性的指标主要是系统可靠度和平均寿命。其中系统可靠度定义为不可修系统在t时刻仍正常工作的概率，平均寿命定义为不可修系统寿命的期望值。

Tom's work at school is above the average ,John's is below the average and Jim's is up to the average.

汤姆的成绩在平均水平以上，约翰的在平均水平以下，吉姆的接近一般水平。

However, the weighted geometric mean method is simpler than the weighted arithmetic mean method, and the former can keep the reciprocity of the improved judgement matrix without transformation.

理论分析表明：虽然这2种方法都具有收敛性，且均可对一致性较差的判断矩阵进行修正，但加权几何平均法比加权算术平均法简洁，且前者无需通过转换，直接保持了修正后的判断矩阵的互反性。

Weighted mean temperatures of Zhangjiakou, Beijing and Xingtai are calculated by using different methods.

运用几种不同的加权平均温度的算法，计算了华北地区张家口、北京和邢台的加权平均温度。
