The third lens group includes a 3rd-group 1st meniscus lens having a concave surface on the image plane, a 3rd-group 1st compound lens formed by joining a 3rd-group 1st negative lens having opposite concave surfaces and a 3rd-group 1st positive lens having opposite convex surfaces, and a 3rd-group 2nd meniscus lens having a convex surface on the image plane side arranged in that order from the screen side toward the image plane side.

第三透镜组包括一个在像平面侧具有凹表面的第3组第一凹凸透镜，一个由具有相对凹面的第3组第一负透镜和一个具有相对凸面的第3组第一正透镜结合的第3组第一组合透镜，和一个在像平面侧具有凸表面的第3组第二凹凸透镜，它们以从屏幕侧到像平面侧的顺序布置。

Double negation in language may be not consistent with mathematically logical rule"minus number multiply minus number is postive" In some sentences, especially whose verb has possible or willing meaning, double negation can change its original affirmative meaning.

自然语言中的双重否定，不像数学上负负得正那样互相抵消，可能会出现一种跟逻辑不一致的现象。

Looking at the world, many people have "a negative, I would prefer people of the world, people of the world can not bear me," mind, but several people can be the same as the interior monologue, as Cao Cao cried out?

放眼天下，许多人都有"宁可我负天下人，不可天下人负我"的心思，但又有几人能像曹操一样将内心独白大声说出来呢？

Quotable Quote: I'm not one for parties and stuff like that.

RW和RF整天就知道把nervous挂在嘴边，哼哼，可咋表现的一点不像呢，可能负负得正吧

Methods Based on the model of round axial symmetry turbulent jet, three simplified categories of the mitral regurgitant jet were proposed.

方法据圆形轴对称自由紊动射流模型，利用超声成像模拟软件FieldⅡ模拟简化的二尖瓣反流的三种情况：①完全正向射流；②中心为正向射流，边缘为负向反流；③上半部分为正向射流，下半部分为负向反流。

In order to decrease total optical length, a design scheme was employed by selecting mechanically compensated zoom lens with a negative compensator, shortening the focus length of variator and compensator, and increasing the distance between front group and variator. An initial configuration was obtained by solving equations of aberrations. According to aberration theory, the aberrations were corrected by using ZEMAX optical design software.

为缩短筒长，采用负组补偿偏离物像交换变焦结构，缩短变倍补偿系统各组元焦距，增加前固定组和变倍组间距的设计方案，通过解初级像差方程求得初始结构，依据像差理论，利用ZEMAX自动设计软件进行像差校正平衡。

Results Teenagers' overall body image depression had a negative correlation with their self regard in four aspects. The score of self regard of boy students who had body image depression was significantly lower than that of girl students; the score of self regard of university students who had body image depression was significantly lower than that of middle school students; the score of self regard of urban students who had body image depression was significantly lower than that of rural students. Teenagers obesity index had a significant positive correlation with their subjective knowledge of body weight. There was no statistical significance between the self regard scores for those BMI in accordance with the self cognition of weight and those BMI with inconformity.

结果 青少年学生总体像烦恼及4个具体方面与自尊都呈显著负相关，有体像烦恼的男生自尊得分显著低于女生；有体像烦恼的大学生自尊得分显著低于高中生，城市学生的自尊得分显著低于农村学生；青少年学生肥胖指数与自我对体重的主观认识呈显著正相关，肥胖指数与自我体重认识一致与不一致者的自尊得分差异无统计学意义。

Left-handed materials have many strange properties,such as negative refractive index, negative group velocity ,perfect imaging,inverse Doppler effect and abnormal Cerenkov radiation.

本文介绍了左手材料的概念、原理和它具有的负群速度、负折射率、理想成像、逆Doppler频移、反常Cerenkov辐射等种种奇异的物理性质。

负折射率介质最早由前苏联科学家Veselago在20世纪60年代从理论上提出来的，是一种具有介电常数ε和磁导率μ同时为负值的介质，它具有诸如负相位速度，负折射率，理想成像，逆Doppler频移及反常的Cerenkon辐射等多种奇异的物理现象。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
