你可以看看我们的球队，他们现在态度认真。

Analyzing the honing principle of spiral bevel gears based on crossing-axis transmission, the mathematical model of the relative sliding speed of the contact point between honing wheel and gear is achieved. It is determined that the pitch cone of honing wheel depends on the number of teeth in the honing wheel and the angle between the common normal of pitch cones and the plane parallel to both gear and honing wheel axes.

分析了基于交错轴传动的珩齿原理，导出珩磨轮与被珩齿轮在啮合点处的相对滑动速度的数学模型，根据该数学模型可以判定珩磨轮的节锥面是由珩磨轮齿数、公法线和与珩磨轮轴线平行的平面夹角所确定。

Then, in 1979, a well-designed study by pediatrician and psychiatrist Herbert Needleman resolved the dispute by establishing a direct correlation between the lead content of a child's teeth and bad classroom behavior. Twelve years later follow-up studies on these children found that those who had the highest lead levels in their teeth as children continued to have school problems through their last year of high school including more school failures, reading disabilities, and lower class standing.

到1979 年，由儿科医生兼精神病学家赫伯特·内德勒曼设计的一个著名实验证明不良的学习成绩与儿童牙齿中的铅含量直接相关，从而为争议下了定论12 年后对这些人的后续研究表明，当年牙齿中含铅量最高的孩子在中学毕业前一直存在学习上的问题，包括考试不合格、阅读障碍和班级排名靠后。

By Visual Basic 6.0 program, taken the distance between hole 200mm and buried depth 120～150mm as the optimization goal, the most optimum parameters range of the mechanism was obtained as follows: the initial angle between planet frame and the line formed from spraying-fertilizer needle-tip and planet wheel axle was -45°～-40°, the initial angular displacement of planet frame was 40°～50°, the distance between spraying-fertilizer needle-tip and the planetary gear axle center was 280～300mm, simultaneously, the semi-major axis of elliptic gear was 29.364mm, the teeth quantity was 23, the ratio of semi-minor axes and semi-major axis was 0.958, the radius of circular gear was 25mm.

对该机构进行运动学分析，建立了数学模型，以穴距200mm和入土深度120～150mm为寻优目标，应用Visual Basic 6.0软件编程得出满足机构运动要求的最优参数范围为：喷肥针尖和行星轮轴连线与行星架的初始夹角-45°～-40°、行星架初始角位移40°～50°、喷肥针尖与行星轮轴心距离280～300mm，此时椭圆齿轮长半轴29.364mm、齿数23、短半轴与长半轴比0.958，正圆齿轮半径25mm。

方以智第一次提出了古人唇音轻重不分、舌音舌头舌上无别、舌音齿音相混、喉音牙音淆乱的理论，切合古音实际，开启了清代钱大昕等人的系统研究。

The cephalometric radiography and ultrasound image of swallowing were recorded just before and after anterior teeth retraction. All the changes and correlation between the variable of anterior teeth and the variable of tongue movement during swallowing were all discussed. The result showed that there was no significant change on duration and magnitude during swallowing after anterior retraction.

以13位符合条件的志愿者为受测对象，分别在前牙退后之前后各取一次测颅X光片及超音波吞咽之影像资料；而后以测颅X光片描绘取得前牙距离、角度的改变比率，另以电脑辅助分析超音波吞咽影像，得到舌头吞咽各分期的时间振幅之改变比率，再进行统计分析。
