Using dilution technique in radiocarbon dating is for the stability of background gas, and maximum age limit required by dilution technique depends on the content of carbon in a sample. 稀释技术~(14)C测年的关键在于本底气的稳定,稀释技术测定的最大年限取决于样品的含碳量。
But the theory of trademark dilution breaks through the limit. 传统理论认为商标侵权仅局限于注册商标。
