Meander Properties of Venusian Channels
Venusian lava channels have meander dimensions that relate to their mode of formation. Their meander properties generally follow terrestrial river trends of wavelength (L) to width (W) ratios, suggesting an equilibrium adjustment of channel form. Slightly higher L/W for many Venusian channels in comparison to terrestrial rivers may relate to nonaqueous flow processes. The unusually low L/W valu...
متن کاملMeander geometry of Venusian canali: Constraints on flow regime and formation time
[1] The similar meander geometries of Venusian canali and terrestrial rivers imply that the in-channel flow regimes may be comparable. This work details meander geometry measurements from ten lowland canali and compares the extensive data set produced to a variety of solar system channels. The meander properties of Venusian canali do not closely match any channel so far observed on the terrestr...
متن کاملCan Venusian Channels Form by Subsurface Thermal Erosion?
Introduction: Channel formation is a unique puzzle in Venus' rock record. Channels, open passages believed to have transported fluid [1], occur in presumed volcanic regions [2], which together with current Venus surface conditions (~450º C [3] and ~100 bars surface pressure [4]), has led many workers, including us, to infer a volcanic origin for venusian channels, although an origin involving l...
متن کاملThe Venusian Environment
1 INTRODUCTION This report presents the first stage of results of a study of the atmospheric environment on Venus. The purpose of the study is to combine existing knowledge derived from measurements, theoretical studies and numerical general circulation models into a single model which can be used to specify conditions such as temperature, pressure, wind, humidity, and dust loading over a wide ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
