High-molecular-weight kininogen (HMWK), also known as the Williams-Fitzgerald-Flaujeac factor or the Fitzgerald factor or the HMWK-kallikrein factor, is a protein from the blood coagulation system as well as the kinin-kallikrein system. It is a protein that adsorbs to the surface of biomaterials that come in contact with blood in vivo. This protein circulates throughout the blood and quickly adsorbs to the material surfaces.

Fitzgerald is a large lunar crater on the far side of the Moon. It lies to the west-southwest of Cockcroft crater, and about two crater diameters to the northeast of Morse crater.
This is an impact crater with features that have become softened and eroded by subsequent impacts in the vicinity. The younger satellite crater 'Fitzgerald W' is attached to the exterior along the northwest. Faint ray material extends from the southeastern rim of this satellite across the western floor of Fitzgerald, although it is unclear if this impact is the source or if it came from the rayed-crater 'Moore F' to the north.
Several spammer craters also lie along the rim of Fitzgerald, with a joined pair along the eastern rim and two more along the western edge. The inner walls display some indications of past slumping and terracing, although these features have become smoothed out with time. The interior floor is a nearly level, featureless plain, with some slight irregularities to the northeast.

Length contraction, according to Hendrik Lorentz, is the physical phenomenon of a decrease in length detected by an observer in objects that travel at any non-zero velocity relative to that observer. This contraction (more formally called Lorentz contraction or Lorentz–Fitzgerald contraction) only becomes noticeable, however, at a substantial fraction of the speed of light; and the contraction is only in the direction parallel to the direction in which the observed body is travelling.

目前肯定和那个美国作家没关系。诗人菲茨杰拉德不知道……只知道他名字FitzGerald来源是诺曼语 fils de Gérald ，意思是法治之矛。可能可以扯上关系…… |
