Urban soil bodies generally exist in the hydrochemistry environment of normal temperature, atmospheric pressure and slow variation. Under this kind of conditions, the chemical components in soil, which are an essential factor affecting the stability of soil, play an important role in this kind of environment, and also have an important influence on surface subsidence, production of earth holes and so on.

城市区域的土体环境一般是处在常态即常温、常压、缓变异的水化学环境中，在这种环境中，影响土体稳定的要素－土体中的化学组份扮演著重要的角色，而其对诸如地面沉降、土洞的产生都有重要影响。

Research staff has not thrown DIRECTLY ACTING PRESSURE REDUCING VALVE ENYZ11X us off course,it was agreed that after the case at room temperature and atmospheric pssure can be normal work,then this failure is apparently due to changes caused by environmental factors.

Experts from meteorological department pointed out that the reason why it snowed at that time is that the atmospheric pressure above the area dropped suddenly to 950 millibars. It was 20 millibars lower than the limit of the normal atmospheric pressure. In June, 2000, the temperature in Koppaonike City, a small town in the plain of Yugoslavia, was over 15 degrees centigrade all along. But in midday of June 17 it dropped suddenly to zero or below. Then a heavy snow fell on. This surprised the local residents. People went to street one after another to have a look.

气象部门指出，当时出现雷电的原因是当地上空气压骤降至950毫巴，比正常气压极限低了20毫巴。2000年6月，南斯拉夫平原小城科帕奥尼克的温度一直在15摄氏度以上，但17日中午，小城的温度骤降到摄氏零度以下，接着天空就飘起了大片的雪花，这一情景让当地的居民惊奇不已，纷纷上街观看。
