The SBT thin films with STO seeded layer on MFIS structure also appear prefer (115),(006) orientation and good crystallinity. The seeded layer of STO effectively resists the diffusion of Bi into Ir bottom electrode on MIM structure. The remanent polarization and leakage current density of Sr0.8Bi2.6Ta2O9+x thin films with STO seeded layers are significantly improved. In MFIS structure, the Sr0.8Bi2.6Ta2O9+x thin films with STO seeded layer are improved memory window and lead to lower leakage current at low voltage.
在具有STO晶种层基材上沉积之钽酸锶铋铁电薄膜於700℃淬火后,无论在MIM和MFIS结构上皆可得完美(115)方向之SBT结晶相,而STO的种晶层在MIM结构中确实可以有效的阻止铋原子扩散进入底电极,而降低漏电流,在MFIS结构中虽然得到一较小极化值,但由於铁电层所分配到的电场值反而因介电常数值降低而增加,因而得到较大的记忆窗。

The following are main contents studied: A finite element method for Navier-Stokes equation with ALE formulation is considered and by combined with theNewmark method of numerical intergration a pressure correction scheme is obtained for the solution of the FE formulation of N-S equation. Because the incompressibility condition can be satisfied approximately in this scheme, the interpolation functions of elements can be equalorder for the velocity field and pressure field. In the ALE formulation the fluid-solid interaction analysis became a three-field coupling problem of the fluid field, the solid field and the fluid dynamic mesh. The properties and charactiristices of this three-field coupling problem are deeply discussed.
研究的主要内容有:主容器中流体大晃动是一种强非线性问题,文中研究了求解ALE描述的粘性流体N-S方程的有限元方法,以有利于大晃动自由液面的跟踪和流体大晃动中非线性现象的描述;并结合Newmark数值积分法推出了求解ALE型N-S方程的压力修正解法,由于这种解法可以近似满足不可压条件,因此可以采用速度场和压力场等阶插值的有限元离散格式,从而较好地解决了普遍采用的不等阶插值解法中,速度场和压力场数值精度不一致、程序编制不便等的不足。

The new ideas from this paper: using mechanics principle study of soil, create a practical test to prove that it could change the physical mechanics character of base soil completely, reducing distortion, improving strength, and eliminating wet or sinking of base soil by seal extrusion during hole formation process at certain replacement rate; it could strengthen the loessial soil base to high bearing capacity to standard value of 300 to 400kPa through seal extrusion to hole formation technology together with rammed cement soil pile. Some value of the parameters adopted by bearing capacity calculation of the composite base of rammed cement soil pile with seal extrusion to hole formation exceeded the criteria of 'Technical Regulation on Building Ground Treatment'.(JGJ79-2002) This technology meet the design requirements and save investment.

Based on the study of chronology and geochemistry of Cd in sediments of the Dongting lake area, we have established an ARIMA model of Cd and Cd/Ca in Quaternary and Holocene period respectively, and discussed Cd evolutionary regularity according to the fitted value and predicted value of the model The results revealed that the Cd evolution has remarkable periodicity of ecogeochemistry cycles, and is correlated with the climate change of alternative cold and warm Cd/Ca is changed with climate, from which the evolutionary history of regional ecogeochemistry can be inferred The changes of Cd and Cd/Ca are basically simultaneous, which showed that the change of Cd is mainly a natural evolution Cd in sediments will rise in the next 30 years and then tend to decrease From the regularity of ecogeochemistry indexes and global environment variation, it is concluded that the natural environment is the dominant factor affecting the Cd deposition
在对洞庭湖区沉积物钻探取样的年代学和地球化学研究基础上,分别建立第四纪和全新世时期Cd和Cd/Ca的时间序列演化ARIMA模型,并据模型的拟合值及未来预测值对区域地球化学环境中Cd的演化规律进行了探讨,结果显示区内Cd的演化有较显著的周期性--环境地球化学旋回,与气候多次冷暖的交替有关;沉积物Cd/Ca受气候环境等控制,分析该比值的变化规律可推测区域环境地球化学的演变历史;Cd和Cd/Ca两者的变化基本同步,说明该区Cd的演化主要为自然演化;未来30年内沉积层的Cd含量仍有逐渐增高的趋势,之后转为降低。从本区环境地球化学指标的时间变化规律及其与全球环境变化的相关联中说明自然条件是区域镉等元素沉积的主控因素。

It might be an abstract syntax tree, if a 'Node' object is used with each parse rule; it might be a simple list as in the smart ASCII example; it might be a modified string based on concatenations and modifications during parsing; or the return value could simply be 'None' if parsing was done wholly to trigger side effects in parse rules.
东西。如果每个解析规则使用了一个'Node'对象,返回值可以是一个抽象的句法树;也可以如同智能ASCII例子中一样,返回一个列表;也可以返回一个字符串,后者在解析中已经被拼接和修改了;或者如果解析工作主要是通过触发解析规则的负效应完成,返回值可以干脆为'None'。
