Chemistry on an experiment called the crystal. First the formation of chemical substances dissolved in water solution, solution Sheng Yu evaporating dish, the evaporating dish placed in steel tripod, the following alcohol lamp heating, control-related conditions, can be a different crystals. Crystal is the fruits of victory, a different experimenter get fruit is not the same: Some people have a beautiful blue vitriol crystals, a person granted a dazzling crystal, more people are harvested white crystals, such as ordinary salt crystal, alum crystals and so on.
In fact, one's life and the chemistry of the crystallization experiments are very similar.
To be crystal, first of all have chemicals, which is the prerequisite and foundation. What is the ultimate prize of a person, with his original prepared "substances". These "material" that is, family background, parental care, education level and the subsequent attitude of the community, etc., no matter who will be affected by these factors, precisely because conditions are different, so that the result was completely different.
Of course, the availability of crystals, or what kind of crystals, and is closely related to experimental conditions. During the experiment, it was accidentally knocked over a evaporating dish, he will gain nothing, It is like the life of those self-serving greed of some Crown expansion will eventually destroy the same.
Heating experiment is a long waiting process that requires persistence and perseverance, while also note that method, first stir a slow fire, after the last use of waste heat evaporated to get crystals. Life it not so? In a young man worked hard and work hard; in middle age, when a down-man, cautious and conscientious work. Not only the warmth of the small family business, but also make contributions to society.
Life on the road, beautiful landscape lot, but certainly there will be ups and downs, disappointment in love blow, pain torture, career setbacks, friends, misunderstandings, and even the family misfortune, death of their loved ones and so on and so forth, no doubt will give us life, various kinds of obstacles the road, we like to do the same as the crystallization experiments to pay persistence and perseverance, with a smile the face of life, and put all kinds of problems in life as a landscape of Another, I believe will ultimately have to get a beautiful crystal.
化学上有一个实验叫结晶。先将化学物质溶解在水中形成溶液，溶液盛于蒸发皿中，蒸发皿置于铁制三脚架上，下面用酒精灯加热，控制好相关条件，可以得到不同的晶体。晶体是胜利的果实，不同的实验者得到的果实是不一样的：有人得到美丽的蓝色胆矾晶体，有人获得耀眼夺目的水晶，更多的人收获的是普通的白色晶体如食盐晶体、明矾晶体等等。
其实人的一生与化学上的结晶实验极为相似。
要想得到晶体，首先要有化学物质，这是前提和基础。一个人最终收获什么，与他最初准备的“物质”有关。这些“物质”即是家庭背景、父母的关爱、受教育的程度以及后来在社会上处世态度等等，不管是谁都会受到这些因素的影响，正因为条件不同，以至于后来的结果完全不同。
当然，能否得到晶体或是得到什么样的晶体，与实验条件密切相关。在实验过程中，有人不小心弄翻了蒸发皿，他将一无所获，这正如生活中某些为官者自私自利贪欲膨胀最终必将毁灭一样。
实验中加热是一个漫长等待的过程，需要恒心和毅力，同时还要注意方法，先是旺火后是文火，最后利用余热蒸干才能得到晶体。人生何尝不是如此呢?人在年轻的时候发奋图强，埋头苦干;在中年的时候踏踏实实做人，兢兢业业做事。既经营着温馨的小家庭，又对社会作出应有的贡献。
人生道路上，亮丽风景多多，但肯定会有风风雨雨，失恋的打击，病痛的折磨，事业的挫折，朋友的误解，乃至家庭的变故，亲人的离世等等等等，这些毫无疑问都会给我们人生道路设置种种障碍，我们就像做结晶实验一样付出恒心和毅力，笑着面对人生，就把种种难题当做是人生的另一道风景，相信最后一定能得到美丽的晶体。 |
