At the same time, we prove that the best linear unbiased prediction of a linear predictable variable Qy and the best linear unbiased prediction βn=(X"sV-1Xs)-1 X"sVs-1ys of regression coefficients of the finite populations βn=(X"V-1X)-1X"V-1y are admissible under matrix loss function and in the class of the linear predictions and the class that contains all predictions, and under quadratic loss function in the class of the linear predictions.

在线性预测类和一切预测类中是可容许预测，而在二次损失函数下其在线性预测类中是可容许预测。

The main results are as follows:（1） the distance a sounding balloon drifts during operation is a lot longer than that is accepted as a horizontal resolution by present numerical models;（2） the positioning scheme presented for sounding balloons is basically applicable to a resolution of 10 km × 10 km;（3） on the whole, the position correction leads to the fact that the resulting analytic increment field is one order of magnitude smaller than the original;（4） analysis of the model predictions shows that soundings, when positioned,leveled soundingswould improve predictions.

结果表明：探空气球在施放过程中的漂移距离远远超过目前数值模式可取的水平分辨率；所设计的探空气球定位方案对水平分辨率为10km 10km的数值预报模式基本是可用的；总的来讲，位置订正对分析增量场的改变与原分析增量场相比小一个量级。模式预报结果显示，探空资料的定位使降水预报效果得到了改善。

The temperature and density and direction of air masses can be determined, and thus the weatherman has historically offered predictions, but these predictions have become increasingly difficult, in part because of the Earth wobble which jerks the Earth about dunder her mantel of air, often at cross currents to the jet stream.

气团的温度、密度以及移动方向可以被确定，因此气象人员可以依据历史数据进行预测。但现在这样的预测越来越困难了，部分原因是地球晃动造成空气运行趔趄，风速带被横向交叉气流所干扰。

The vertical and horizontal postglacial rebound is detected by measuring site velocities and length rates of baselines respectively using data from space geodetic measurement of VLBI. The comparison and correlation analysis between space geodetic results and predictions of postglacial rebound from the geophysical model ICE-4G is shown. And the system error between space geodetic results and ICE-4G predictions is also discussed.

利用VLBI的实测数据和ICE-4G模型，采用实测站速度和基线长度变化率分别检测了冰期后地壳回弹的垂直运动和水平运动，并对用空间技术求解的实测值和用ICE-4G模型求解的估计值进行了数理统计分析，最后给出了实测结果与地学模型估计值之间的系统差。

Science is usually composed of four parts:(1)scientific facts;(2)the explanations to the scientific facts by guesstimated causes;(3)deducing out the relevant laws,formulas and predictions from these guesstimated causes as the premises;(4)strictly verifying these laws,formulas and predictions.

科学通常由四个部分组成，科学事实；用猜测的原因对科学事实进行解释；推演出相应的定律、公式、预言等；对这些定律、公式、预言等进行严格检验。

At last, through the utilization of Monte Carlo algorithms , we can provide the most accurate statistical predictions for various services . This thesis provides some methods to solve the problems on simulation , one is about the propagation tunning for WCDMA , the other is using a new call admission control algorithm to control the system loads . These will result in more accurate predictions and provide references for the construction of WCDMA.

文中针对仿真预测中容易出现的问题进行了探讨，重点介绍了WCDMA传播模型的校正方法，同时使用一种新的基于负荷估计的呼叫接入控制算法来更好地模拟用户的干扰水平，在一定程度上提高了仿真预测的准确度，为将来网络的建设提供了借鉴。

But because difference among the predictions of different theoritical models in low z region is small, it is hard to tell us which model is more compatible with the experimental result. Our results from high z binning show a good consistence with the predictions based on z-dependence SU (3) asymmetry, quark-Diquark and pQCD model, which indicate the ud quarks in Λ hyperons provide contributions as well as s quark and the contribution is the function of z.

高z区间分法下归一法和螺旋度平衡法的分析结果显示同z依赖的SU（3）对称模型、夸克--反夸克模型和pQCD模型预言的纵向自旋转移值S〓和z的关系较一致，从而表明Λ超子中u夸克不但对Λ的极化有贡献，而且其贡献和Λ携带的能量份额z有关系。

The first one briefly,reviews the present status of studies on societal and economical responses to earthquakes and earthquake predictions in China during the recent three years,mainly including introduction,the outline of general work.the object and task of the research work,especially the social investigations of earthquake predictions,false alarms,earthquake rumours,earthquake disasters and some enlightenments gained from them,as well as international interflows of materials and activities of commu...

扼要回顾了近三年多来中国在地震和地震预报社会经济影响研究工作方面的进展情况，主要包括引言，一般工作概况，此项研究工作的目的和任务，特别是对地震预报、地震虚报、地震谣传、地震灾害等不同类型的社会调查及从中得到的几点启示，以及国际资料交流及通讯交往活动等。

Sometimes he is right,but usually his predictions have to be taken with a grain of salt.

有时候他是对的，不过，通常听他的预测要打折扣。

However, many of his predictions range from the absurd to the, well...

然而，他的许多预测内容都是从荒谬开始的。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
