Using two symmetrical plano-convex lens system to fabricate grating was analyzed and the characteristic of diffraction wavefront aberration of the grating was summarized by ray tracing program using MATLAB siftware.

分析使用两个对称的单平凸透镜光路制作光栅并用MATLAB编写光线追迹程序分析了所制作的光栅的衍射波像差的特点，经计算得出在较小焦比D/F情况下其衍射波像差仅与两支光路点光源的调节偏差之差有关与单独的各个偏差无关；初级像差中球差很小几乎可忽略：彗差仅与垂轴调节偏差之差成线性关系；像散仅与轴向调节偏差之差成正比；且当平凸透镜的焦比D/F增大时，各像差项迅速增大。

I like for you to be still:it is as through you are absent And you hear me from far away and my voice does not touch you It seems as through yours eyes had flown awayAnd it seems that a kiss had sealed your mouthAs all things are filled with my soul Your emerge from the things,fill with my soulYou are like my soul,a butterfly of dreamsAnd you are like the word melancholyI like for you to be still ,and you seem far awayIt sounds as though you are lamenting,a butterfiy cooing like a doveAnd you hear me from far away,and my voice does not reach you Let me come to be still in you silenceAnd let me talk to you with your silenceThat is bright like a lamp,simple as a ringYou are like the night,with its stillness and constellations You silence is that of a star,as remount and candid I like for you to be still:it is as though you are absent Distant and dull of sorrow,as though you had died One word then,one smile,is enoughAnd I'm happy,happy that's not true

我喜欢你是静静的：仿佛你消失了一样你从远处聆听我，我的声音却无法触及你好像你的目光已经游离而去如同一个吻，封缄了你的嘴如同我积满一切的灵魂而你从一切中出现，充盈了我的灵魂你像我的灵魂，像一只梦想的蝴蝶你如同＂忧郁＂这个词我喜欢你是静静的：好像你已远去听起来像在悲叹，一只如鸽般细语的蝴蝶你从远处聆听我，我的声音却无法触及你让我在你的静谧中安静无声并且让我借着你的沉默说话你的沉默亮若明灯，简单如环你如黑夜，拥有寂静与群星你像我的灵魂，像一只梦想的蝴蝶我喜欢你是静静的：仿佛你消失了一样远隔千里，满怀哀恸，仿佛你已不在人世彼时，一个字，一个微笑，就已足够而我会感到幸福，因那不是真的而感到幸福

The software includes two modules. One is to evaluate and manage how smoke bomb can shield the thermal images, which can be used as the guide in the development and improvement of thermal smoke bomb. The other is to process the data of thermal images under smoke-screen to locate target in the shortest time and improve the quality of the target thermal images, which can be used as the reference to further design for development and improvement of thermal image.

该软件主要包括两大功能模组：1红外烟幕对热像图遮蔽效果的评价和管理模块，利用该模块研究红外烟幕环境对红外与热像传输影响的定量测试与评价，指导红外烟幕弹的研制与改进；2红外烟幕遮蔽条件下热像图增强处理模块，该模块主要是研究采用一定的处理方法，改善烟幕遮蔽条件目标热像图的观察效果，争取最短时间发现或识别目标，为今后热像仪的研制设计、改进提供参考依据。

The Guo rill thought "the life likes glass of thick liquors, does not pass through the over and over again refinement, cannot have such deliciousness"; But Mr. Liu Dingzhong thought "the life is a lasting striving for success, likes Steel knife, wants to be sharp must rub in the stone; Does the firewood like a bunch, must shine must throw oneself into the flaming bonfire; Like a shell, only has undergoes sea Tao to wash out only then can be brilliant; Like a star, only has on the track moves only then does not send crashes......"

郭小川认为"生命像一杯浓酒，不经过三番五次的提炼，就不会有这样的可口"；而刘定中先生则认为"生命是一场持久的拼搏，像一把钢刀，要锋利就得在石头上磨；像一捆干柴，要发光就得扑入熊熊篝火；像一只贝壳，只有经受海涛的冲刷才会光彩夺目；像一颗星，只有在轨道上运行才不致坠落……"

Don't ask me, I forgot totally about the what kind of melons is that already. Its appearance is like watermelon, however, its pulp is just like winter melon.

它西瓜不像西瓜，冬瓜不像冬瓜，有像西瓜外观的皮以及像西瓜籽子的白色籽子，也有像冬瓜的肉。

All the seven order ocular aberrations are measured with the aberrometer. The ocular aberrations are described with Zernike polynomials, two-dimensional and three-dimensional wave-front aberration maps.

该像差仪能测量出人眼的全部七阶像差，采用Zernike多项式、两维和三维波前像差图对人眼像差进行了描述，给出了计算各项波前像差的均方根的公式。

There was no significant difference of higher order wavefront aberrations between emmetropic and ametropic eyes. Comparing the age of 40 years or less with the age over 40 years, there were significant differences in RMS3 between the two under 7 mm pupil size, and statistical diffenences in RMS6 and RMSh between the two under 4 mm pupil size.

除第2阶像差均方根(RMS2)以外，正视眼及近视眼各阶像差平均RMS值在7 mm与4 mm瞳孔下，差异均无统计学意义。40岁及以下者与40岁以上者相比，在7 mm瞳孔时，两者第3阶像差均方根(RMS3)差异有统计学意义；而在4 mm瞳孔时，两者第6阶像差均方根(RMS6)及高阶像差均方根差异均有统计学意义。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
