There exist negative correlations between the ionic porosity, which is a measure of atomic packing density in minerals, and Ar and H diffusion activation energies. Thus ionic porosity can be used to predict element diffusion coefficients.

孔隙度作为矿物内部离子堆积密度的一种量度，它与Ar和H的扩散活化能之间存在负的线性相关性，因而可以用于预测元素在矿物中的扩散系数。

It also gives the definitions and stochastic properties of pure random process, random walk process and AR(1) autoregressive process, and analyses the simulative data of three typical random processes using wavelet analysis, frequency spectrum analysis and time-correlation analysis. The stochastic properties of time series and the trend component, the time length of time-correlation and the properties of main frequency of these three typical random processes are summarized as the templates for further research.

The time-varying channel was modeled as an autoregressive process and a low-dimensional Kalman filter based on pilots was used to estimate the AR parameters,and the LS algorithm was adopted to track the time-varying channel fading factors.

采用AR过程对信道进行建模，利用基于导频的低维Kalman滤波算法进行信道估计，并采用LS算法估计时变的信道衰减因子。

All the volcanic rocks present younger K-Ar age (less than 5Ma), which can be termed as Cenozoic rocks. In general speaking, volcansim can be dividied into two eruptive stages. In the first stage, volcanic rocks for Pliocene epoch (4. 4-5Ma) consist of basanite and tephrite, which distributed on Mt. Crater, Cape Bird, and southern bank of Bonney Lake; In the second stage, volcanic rocks for Quaternary (less than 1 Ma) are mainly composed of latite, which are distributed on Cape Rodeys and Cape Evens.On the basis of geochemical data such as major elements, trace elements , rare earth elements, isotope, microprobe analysis, combined with main achievement taken by previous researcher in this area, conclusions are drawn basically as follows

所喷发的火山岩K-Ar年龄值均小于5Ma，为新生代火山岩，大体上可以分为两个喷发阶段，第一个阶段为上新世火山岩(年龄值为4.4-5.0Ma)，主要由碧玄岩和碱玄岩组成，分布于罗斯岛上的克雷克特山、鸟角和泰勒谷的博尼湖南岸；第二阶段为第四纪火山岩(年龄值均小于1Ma)，主要由安粗岩组成，分布于罗斯岛上的罗德角和伊万思角，通过主要元素、微量元素、同位素结合电子探针以及前人的研究成果，我们大体上可以得出如下认识

Through comparing the Ar (e,3e) double ionization experimental results at low collision energy with the theoretical calculation based on the first Born approximation which include the first order mechanisms SO and TS1, the symmetry breaking about the direction of the momentum transfer shows that the non-first order effects (such as two-step 2 mechanism) play an important role.

通过比较Ar在低碰撞能量下的(e ，3e)双电离实验结果和基于包含一次作用机制SO和TS1的一阶波恩近似的理论计算结果，表明在动量转移方向上对称性的破坏显示非一次效应(例如二型两步作用机制)起非常重要的作用。

Ethanol vapor was introduced into the fluidized-bed from a temperature-controlled bubbler by the flow of Ar.

该方法是让AR气流直接携带乙醇蒸汽进入反应器，用流化床反应器代替石英舟，使乙醇蒸汽与催化剂混合更加均匀，有利于SWCNTS的生成。

We require to increase the bulk of AR-26s on order No.

我们想增加99725号订单上AR-26的数量。

BURG arithmetic is an early effective arithmatic put forward to resove AR aeguments which is based on data.

BURG算法是较早提出的建立在数据基础上的AR模型系数求解的有效算法。

Our result has shown that within several seconds of 600 W, Ar, O2 or N2 plasma pretreatment, PP fabric and PE film are activated at surface, so as surface tension of film and capillary attraction of fabric are both augmented.

实验结果显示：对於 PP 不织布与 PE 膜，以600 W 激发 Ar 、 O2、 N2三种气体电浆处理，皆可於极短时间约数秒至数十秒，即可使基材表面活化，形成亲水性或增进表面的毛细作用。
