Other well-observed regional factors, including low population density and the high prevalence of gun ownership, may contribute to the noticeably elevated risk, the study team acknowledged.

其他well - observed区域因素，包括低密度、高度盛行的枪支，可能导致明显的风险升高，这个研究小组承认。

Results Observed from orthpanotomography the density of bone in cysts increased significantly, with new bone formation and decreasing of the vulcanicity of cysts.

结果通过曲面断层片中观察发现囊肿腔内骨密度增高，有不同程度的新骨形成，囊肿体积变小。

The exciton absorption resonaces (HH and LH) and step accumu-tive density Of state have been observed.

But it would take an awful lot of ice to lower the density to what was observed.

While West has observed a positive power law in that the demand for roads and gas stations also decline as density increases, sooner or later that has to end.
