升华

Every abjuration have to be once sublimation,or not,please don't give up it;every choice have to be once sublimation,or not, please don't make a choice.the most pleasure for people is to get the things that we want by our struggle.

每一次放弃都必须是一次升华，否则就不要放弃；每一次选择都必须是一次升华，否则就不要选择。

This article proposes experimental studies on the sublimation behavior of dry ice in a airtight columniform container of Ф 159×840mm. Four typical processes are analyzed under the conditions of heat-preservation, heat transferring, air and airlessness respectively.

对干冰在尺寸为Ф159mm×840mm的圆柱体密闭容器中进行了绝热条件与有热交换、有空气与排出空气这4种过程的升华实验，获得了干冰升华过程的温度—压力曲线。

Over the years, I hesitate to enjoy the winter, turning her body into the cold in the winter, so winter's cold can trigger my feelings, so that the winter cold freezing my humble thoughts, so that the cold solidified my thoughts mature , so that mature thinking sublimation my soul, so that sublimation of the soul collection sunrise moonset, collecting rivers and lakes, so that sunrise and moonset, rivers and lakes, ancient loyal years ......

多少年来，我都义无反顾地喜欢冬天，把自己的身体融入到冬天的寒冷中，让冬天的寒冷能引发我的感慨，让冬天的寒冷凝固我卑微的思想，让凝固的寒冷成熟我的思想，让成熟的思想升华我的灵魂，让升华的灵魂收藏日出月落，收藏江河湖泊，让日出月落、江河湖泊亘古忠诚的岁月

The attention is focused on the effects of heat flux, physical parameters of porous plate, pressure of feed water and placement on performance of sublimator.

探索了多孔板的制造方法，设计了水升华器试验组件和试验装置，对不同的多孔板升华器在恒热流条件下进行了试验研究。

Test results have proved that the basic design concept of sublimator is feasible and that sintered powder porous plates can meet experimental needs of sublimator.

试验结果证明文中提出的升华器基本的设计概念是可行的，粉末烧结多孔板可以满足升华器的试验要求。

Breakthrough characteristics of sublimator are discussed.

试验重点研究了不同热流密度、多孔板物理参数、给水室压力及升华器放置情况对升华器性能的影响，并对水升华器的击穿特性进行了讨论。

The sublimation mechanism is that the reaction product vinyl acetate acts with Zn2 to produce a volatilizable complex,then sublimates to gas phase.

升华机理是反应产物与Zn2作用生成挥发性络合物再升华到气相中去。

Vacuum freeze-drying is a technology used for drying, color protection, fresh keeping, or nutrition preservation of food, biologics, biomaterials, or micro/nano materials. Its principle is to use sublimation principle under the vacuum state, and to obtain dried products, whereby frozen water in the material sublime or shift directly from the frozen state to a gas state, and watery element is removed without melt.

冷冻真空乾燥技术是一项适用於食品、生物制品、生医材料、微奈米材料的乾燥、护色、保鲜、保存、保营养成分的技术，其原理是在真空状态下，利用升华原理，使预先冻结的物料中的水分不经过冰的融化直接以冰态升华为水蒸气而除去，从而获得乾燥制品。

We reproduced the Munsell chips whose hues are 5R, 5YR, 5Y, 5GY,5G, 5BG, 5B, 5PB, 5P,5PR and values are 3, 5, 7, and chromas are 2, 4, 6, 10 using the sublimate printer. We then calculated the color differences ΔEab between the reproduced chips and the standard chips.

而Munsell色票为目前工业设计及平面设计等各行各业最常用的色票，因此我们以Munsell 色票中的十个主色相、彩度C=2，4，6，10、明度V=3，5，7的色票为本研究的标准色样，用热升华式印表机进行色彩复制，再计算出复制色票与标准色票的CIELab色差，以探讨热升华印表机复制Munsell色票的可行性。

The results show that compound 1 combusts, decomposes, sublimates and loses weight simultaneously at 258℃ in oxygen, and the heat emitting from the combustion is far greater than that absorbed by sublimation.

结果表明，在氧气气氛下，三（2，4-戊二酮）合铱在258℃时开始燃烧分解，并伴随著升华失重，燃烧释放的热量远大于升华所需的热量，气相中的主要分解产物为2，4-戊二酮、二氧化碳和 2，5-二甲基-3-乙酚基映喃等。
