方格微尺
英文
grating micrometer-
So in one hand it requires the wafer ' s diameter to be more large in order to enhance the productivity, and on the other hand it puts forward more strict requirement about the crystal perfection and electricity character. especially the electronic character and the equality of micro - area in the crystal wafer has become the key factor to determine whether the device can be made on it or not. so the resistivity measurement of micro - area become one most important procedure in the chip machining. to ensure the produce quality of chip and the perfect performance of final production, the four - probe testing technology need to be deeply studied
圖形日益微細化,電路尺寸不斷縮小,目前ic製造以8英寸、 0 . 13 m為主,預計在2007年左右將以12英寸、 65nm為主,這一方面要求圓片直徑不斷增大以提高生產率,另一方面對晶體的完美性、機械及電特性也提出了更為嚴格的要求。特別是微區的電學特性及其均勻性已經成為決定將來器件性能優劣的關鍵因素。因此,微區電阻率的測試成為晶元加工之中的重要工序。Based on theoretical analysis, microbubble drag reduction is due to structure change of turbulent boundary layer caused by the microbubbles. experiments testify microbubble drag reduction for turbulent boundary layer, as well as bubble size, main flow velocity, etc. affecting the reduction ; with proper flow field model, turbulent model and difference scheme, numerical methods simulate the effect of boundary layer and bubble numbers on dray reduction
理論分析提出微氣泡降阻機理在於其引起湍流邊界層結構的變化;實驗證明了微氣泡對湍流邊界層的降阻作用以及氣泡尺度、主流速度等對降阻作用的影響;數值方法利用適當的流場模型、湍流模型和差分格式,模擬邊界層和氣泡數等對降阻的影響。Because the feature size of subwavelength diffractive microlens is smaller than the incident wavelength, scalar diffractive theory cannot be used to the analysis. it also precludes rigorous vector coupled - wave theory for its finite and aperiod structure
由於亞波長衍射微透鏡的特徵尺寸小於入射波長,因此不能採用標量衍射理論來分析,又由於它是有限非周期的結構,嚴格的耦合波方法對它也不適用。In this paper, the governing differential equations of double pendulum is established with the lagrange methods, the stability margin of corresponding linear equations are obtained by the multiple scale method
採用拉格朗日方法建立參數激勵雙擺的控制微分方程,通過多尺度法對其線性化方程進行分析,獲得穩定性邊界。The two - dimensional body - fitted grid was created by method of partial differential equation and zonal method. the k - equation subgrid - scale model was used to simulate the turbulent viscosity, the chemical reaction rate was determined by the subgrid ebu combustion model and the heat flux model was employed for the heat flux
運用偏微分方程和區域法生成二維貼體網格,湍流模型採用k方程亞網格尺度模型,燃燒模型採用亞網格ebu燃燒模型,採用熱通量輻射模型估算輻射通量。分享友人
