The electronic heating evaporator in the high-side gravity recirculation system in ANSI/ASHRAE 64-2500 standard is replaced by a new type plate evaporator which is more effcient and energy-saving, because the cold water outlet from the evaporator that is used to heat the cryogen can be used once again to cool the air in the air inlet trunk; an air processing unit is designed in the lab design, so to imitate all kinds of weather in each season in every location of China at any time the test is being made; the data selection system can send all the data in the test to the computer at one time, and to reduce the cost of the test some data which is more stable are read manually through traditional meters if this can not sacrifice the precision of the test.

本文的设计中用效率更高的新型板式换热器代替了原ANSFASHRAE 64——2500标准中压缩驱动循环系统中的电加热蒸发器，加热冷剂后得到的低温淡水还可以用于冷却进气通道中的空气，不仅提高了效率，而且更加节能；实验室方案中增加了空气处理系统，可以实现随时对全国各地各季节的空气状态进行模拟，方便实验的进行；采用数据采集系统将数据整体采集到电脑中方便数据处理，而且对于变化频率不高相对较为稳定的数据采取传统仪表进行人工读数，在保证测试结果准确性的前提下降低了成本。

Because different cell lines may show various levels of susceptibility to adenovirus infection and virus production, non-selectively replicating wtAd5 was used to be a comparison with the tested conditionally replicating adenovirus CNHK500.ONYX-015, the first replication-competent adenovirus entered into clinical trials was also used to be a comparison. We used virus proliferation assay, cell viability assay and western blot to evaluate the proliferation and cytolysis selectivity of CNHK500. Results demonstrated that the CNHK500 virus proliferation multiples in breast cancer cell lines after 48 hours is similar to that of wtAd5, ONYX-015 virus proliferation ability is less than that of CNHK500 in cancer cells.
