In the third stage, the column-shaped ice crystals grew mainly in its length and the ice crystals had the acerose shape gradually, and the growth rate of frost thickness increased rapidly to 3-5.8 times that in the second stage. It is found that the performance degradation of the ASHP unit was caused by the wall temperature drop of the evaporator, the rapid increase in the frost thickness, and the decrease in the air flow rate.18Refs.

对实验结果的分析表明，热泵机组性能恶化主要是由于蒸发器表面温度下降、霜晶形态变化引起霜层厚度快速增长及空气流动阻力增加导致风机流量下降三个因素之间形成的恶性循环所致，其中换热器表面温度下降引起的霜晶形态变化起到了至关重要的作用。

A dyn amical visual analysis is done about a shrouded impeller which is used in a large-scale compressor unit on the basis of visual theory and finite element analysis theory with the combination of SolidWorks and ANSYS . With the vibration characteristics of the impeller under the inertial force, we get to know whether the impeller with given conditions can avoid from the resonant frequency or not and its influence of vibration on system.

以可视化理论、有限元分析理论为基础，结合三维建模软件SolidWorks和有限元分析软件 ANSYS 对某压缩机组用闭式叶轮进行动力学可视化分析，得到其在惯性力作用下的振动特性，可以判断其在给定工况下能否避开共振频率以及评估其振动对系统的影响。

METHODS: The concentration of ozone that was transmitted by ozone generator at different time was determined by using iodine titrimetric method. According to the bactericidal assay of quantitative vehicle, the bacteria on the ozonized vehicles and unozonized vehicles was washed, 50μl eluant was seeded on the TSA plates. The TSA plates were put into the anaerobiotic incubator (90% N2, 10% CO2, 37℃). After 24 to 48 hours, the CFU on the plate was counted.

用碘滴定法测定打开臭氧发生器不同机组及不同时间时的臭氧浓度，按载体定量杀菌试验，将经臭氧作用的载体与相同环境下未经臭氧作用的载体上的细菌洗下，各取洗脱液50μl，接种于TSA平板并置厌氧箱(90%N2， 10%CO2， 37℃)培养24~48h后，进行活菌菌落计数。

But now a relief business card printing and membership card equipment, with the valid wider circle applanation 凸印 machine, with a general Rotary 凸印 machine, paatprofessional, hapalogenys-back or subordinate unit-sticker business card printing and membership card-making machine, so I believe.
