| It is believed that a minor perturbation in solar heating caused by orbital changes could lead to another ice age or warming period. |
| Sometimes a small perturbation of a system could cause it to switch from one pattern to another. |
| All of these can be shown by hematologic abnormalities or hepatomegaly with liver test perturbation. |
| The perturbation theory given here is adequate to show how the two atoms can form a diatomic molecule through the covalent bonding mechanism. |
| At present, the most common and serious anthropogenic perturbation of lakes is eutrophication due to increased nutrient availability. |
| In cold advection the cyclonically rotating ascent to the right is opposed by decent forced by the linear pressure perturbation. |
