针对频域最小方差无失真响应方法在源方位快速变化情况下稳定性差的问题，提出了一种基于时域解析信号的MVDR自适应波束形成方法TAMVDR(Time-domain Aanlysis MVDR)。

In the case of double line spectrum, modulation ratio changes as a periodic function of light-path difference with the period of λ〓/△λ.

在有一定宽度的谱线情况下，调制比随光程差的增加而衰减，因而存在一个最大光程差λ〓/△λ。

The results showed that the growth rate of Phytophthora infestans and the number of sporangium on rye medium were best and oat medium second, but V8 medium and PDA were worst.

结果表明，马铃薯晚疫病菌在黑麦培养基上的生长速度最快，产孢量最大，燕麦培养基次之，V8培养基和PDA最差。

In the area with the tuberculosis as a frequently-occurring disease,most of the cases could be diagnosed definitely by using the examination of CT and cystoscopy,seeking tuberˉcle bacillus in urine by microscopy were valuable for early diagnosis,B ultrasonographycould not provide effective inˉformation for diagnosing,KUB+IUP could provideinformation for the diagnosis and prognosis,conservative treatment brought poor curative effect,early treatment and regular using antituberculotic were significant to the prognosis.

在结核病高发地区，CT和膀胱镜检查是最重要的方法，尿中找抗酸杆菌对早期诊断有意义，B超检查特异性较差，KUB+IUP对诊断和预后判断有意义，保守治疗效果差，早期治疗和正规抗痨治疗对病人预后有重要意义。

For sheet-fed offset presses, plant height should be not less than 3. 5 m, apart from considering the height of the machine, you should have the height of the docurments underpan, scrolling the height of the steel tube (or the height of the 88 car activities), the height of the gantry and the height of the hoist, and so on, the best plant height of 4 m through 4. 2 m, height of less than 3 workshop. 5 metres, off off or more new equipment can occur when lifting into place.

差于单张纸胶印机来说，厂房低度答不超出3.5米，除了思考机械的低度边，还答有装箱底盘的低度、转不静钢惯的低度（或者勾当88小车的低度）、龙门架的低度和起轻葫芦的低度等，最坏的厂房低度为4米到4.2米，若厂房低度超出3.5米，差开或差开以上陈摆设起轻到位时会爆发便当。

Second, according to the characteristic of soft-ground ,when we disposed of the obser-vation data of every period from the earth subsidence network, we chose three adjustment ma-thematics models including adjustment by classics; adjustment by free network and adjustment by selecting proposal stable points to deal with the solution .

其次根据软土地基的特点，为达到观测成果能合理处理目的，在沉降变形监测网数据处理时，利用了三种平差数学模型即经典平差、自由网平差和拟稳平差分别进行观测基准网的解算，并把求算结果进行比较对照，从而选出最合理的能符合本场地实际条件的一组解算成果作为我们后面的变形成果精度分析的依据。

Throughout comparing the above estimating methods, we have the following results: the estimators of the moments of the errors does not depend on the random effects, and that of the random effects does not depend on the errors, and then the corresponding asymptotic variances are very simple and optimal; when the random effects are multivariate, we can not construct different estimating equations for the random effects and errors respectively, which results that the asymptotic covariances of estimation are very complex and then the estimating efficiency is bad.

比较上述两种估计法，我们发现：当随机效应是一维的时侯，误差的各阶矩的估计不依赖不可观测的随机效应，随机效应的估计也不依赖误差，因此，估计的渐近方差结构特别简单也是最优的；而当随机效应是多维的，因为随机效应的协变量的影响，我们没有办法针对随机效应和误差的各阶矩分别建立估计方程，这导致所得的估计的渐近方差或者协方差矩阵特别复杂，从而估计的效果不是很好。

With sea level rise,the partial tide amplitude will be increased,but diminish in some part area;meanwhle tide counting position of partial tide moves unceasingly to southeast direction;Tide amplitude change causing by sea level rising can be taken the Lvsi port as the boundary,to the north,partial tide amplitude enhances unceasingly,and to south it diminishes,especially in destroyed Yellow river it has less enhancement;The region where has the largest increasing partial teide amplitude also the palce which has the quickest erosion rate.sea level rising has a good relation with the beach erosion.

2海平面上升后分潮的振幅将随之而变大，但在部分区域，分潮振幅随着海平面上升而减小；无潮点相对于现有的无潮点位置均向东南方向偏移；海平面上升导致的潮差变化，大致以吕四为界，以北随着海平面上升，分潮的振幅不断增大，以南振幅减小，其中在废黄河口附近的增幅也相对较小；潮差增大幅度最大的地区刚好是岸滩侵蚀最快的地区，海平面上升与岸滩侵蚀存在很好的对应关系。
