First, the nonlinear ls problem without constraint is converted to that subjected to inequality constraints by putting constraints on the do as of the received signals and toas of the first arrived signal with geometrically based single - bounce ( gbsb ) statistical channel model and cost - 207 model. then, a penalty function is used in the estimation of ms position
首先,用基於幾何結構的單次反射圓模型和cost - 207模型,對期望定位用戶的各條多徑信號的波達方向和最先到達多徑信號的時間進行約束,將傳統的解無約束的非線性最小二乘定位問題或近似線性最小二乘定位問題轉化為解不等式約束的非線性最小二乘定位問題;然後,用內點罰函數法估計移動臺的位置。Dlc and a - sic : h films were prepared by the rf glow discharge and the reactive sputtering method respectively. there were two reasons that we chose y rays, ultraviolet ( uv ) photons, and neutrons as radiation sources. one is that y rays, uv photons and neutrons irradiation are serious at outer space and / or nucleus irradiation enviromentthe other is that the study on y rays irradiation on the films is a new and an important directioaotherwisejirnited reports have been made of the investigation on the uv photonsjieutrons irradiation influences on these films
本文分別採用射頻( 13 . 56mhz )等離子體cvd及射頻反應濺射方法制得了dlc及a - sic : h薄膜。文中主要選擇y射線、紫外光及中子作為輻照源有兩方面的原因:一方面,在外層空間, y射線及紫外光輻射十分嚴重,而在核輻射環境下y射線及中子輻射也不可忽視;另一方面, y射線輻照這兩種薄膜完全是一項開創性的工作,同時國內外對紫外光子、中子與這兩種薄膜作用的研究也很少。Tem, xrd and electronic energy spectrum indicated uniform tio2 particles laid over surface of sio2. for discussing mechanics of the process in adsorption phase reactor technology, the author designed temperature, concentration and reaction time experiments. then the adsorption and reaction mechanics were gained with kinds of analytical methods
為了探討吸附相反應技術中的過程機理,作者設計了溫度、濃度以及反應時間等實驗,並結合x射線衍射儀( xrd ) 、透射電子顯微鏡( tem ) 、電子能譜儀等各種表徵手段,得出了吸附過程和反應過程的各自機理。
