一般估计

Excepting the conventional methods of surveying samples, such as simple random sampling, stratified sampling, cluster sampling, systematic sampling, liner regression sampling, ratio estimator, two-stage sampling, double sampling, rotate sampling, non-probability sampling, there is sequential sampling and mark-recapture, particularly mark-recapture was introduced in detail.

针对生物资源的调查，除了一般抽样方法如：简单随机抽样、分层抽样、整群抽样、系统抽样、双重抽样、二阶抽样、样本轮换、比率估计、线性回归抽样和不等概抽样，还有序贯抽样和标记-重捕获方法，这里特别详细介绍了标记-重捕获方法。

In the case of the same sensor number,this method which adopts appropriate array geometry arrangement can improve the resolvability of DOA estimation more obviously than the uniform linear array.

在阵元数一定的情况下，该方法可使阵列的方位分辨率较之均匀线阵有较大的改善，而且还克服了一般稀布线阵方位估计模糊和去相关能力差的缺点，成功地将空间平滑MUSIC这一经典方法用于非等矩阵。

As for those who wish to improve the stomach to improve in the roundworm, is estimated to be very detailed, detailed to the general Web site does not store food ---- Alibaba Group as a whole by virtue of the available number of Internet users, I would like to do this step is not difficult .

至于想改善改善肚子里的蛔虫，估计更是会非常详尽，详尽到一般网站所没有的小吃小店----凭借整个阿里巴巴集团所掌握的网民数量，我想做到这步并不困难。

According to Zhao Jing estimates, if the capital cost of 100 yuan per square meter, the share premium and other costs of the proportion of development costs down to the general level of foreign countries, will enable housing development costs immediately dropped every 58 square meters.

据赵基嗯估计，如果资金成本100元每平方米，股份溢价及其他费用的比例下降到开发成本的一般水平的外国国家，将使房屋开发成本每立即下降五八平方米。

Modem spectral estimate is generally used to process the random signal. But only stationary Gaussian signal can be processed by this method. Using the higher order spectral analysis can overcome these defects.

处理随机信号通常使用现代谱估计方法，但是这种方法一般只能处理平稳的高斯信号，使用高阶谱分析可以克服这些缺陷。

For example,,,where .2.Convergence of the iterative method: firstly I give a new upper bound for the spectral radius of iterative matrix , where is a double strictly diagonal dominant matrix.

迭代法的收敛性分析：首先给出了一般迭代阵谱半径新的上界估计，其中矩阵为双严格对角占优矩阵，是一种比严格对角占优更广泛的矩阵类。

Generally,it is considered that cotton fibre is a column and its surface is smooth.The surface structure of Xinjiang long fine hair cotton is researched by using electronic microscope scanning (S-570 Japan).The result shows that the cotton fibre is not a column,but is spiral.The fibre of only 15%does not twist.The surface of the fibre is not smooth,and there are burrs on it.These characteristics would be another important factor effecting the stickability of cotton.

一般认为，棉纤维呈圆柱状，纤维表面是光滑的，笔者以新疆长绒棉为研究对象，用日立S-57日扫描电镜，研究了棉纤维的表面结构，结果表明，棉纤维并非呈圆柱状，自然状态下呈螺旋形，象氨基酸那样，根据概率估计，没有扭曲的约占15%，棉纤维表面并不光滑，有毛刺，这种结构特性是影响棉花粘着性的又一重要因素。

The asymptotic unbias edness and the strong consistency and rate of convergence under given conditions are obtained.

在测度弱收敛的意义下，研究了一般概率测度μ的核估计μn，得到了它的渐近无偏性、强相合性及在给定条件下的收敛速度。

Because of this, regular Least-square analysis method can not be used in this type of test.

本文根据客观特点，依据新的模型和最优线性无偏估计原理，对于这种试验提出了一种新的分析方法——一般最小二乘分析。

Heating billet temperature cannot be detected in the hearth. Only by detecting temperatures of the stove side or hearth with estimation from mere experience could lead to great error on the measurement of billet temperature and affect the quality of post-processing accordingly; Overheating also exists in the heating process, and the quality of product is sway by overheating oxidation. Though infrared thermoscope is used to detect the temperature of billet when it is taken out of the stove, precision is still affected because of the oxide layer on the surface.

燃气与空气的配气量比例，一般通过人工调节，未实现按加热条件自动动态调节；无法在炉膛内检测被加热钢材的温度，只能通过检测炉壁或炉膛温度，再凭经验估计钢材温度，结果是钢板温度误差大，影响后续加工质量；钢材加热存在表面过烧现象，有时表面烧损、氧化严重，影响产品质量；尽管钢材出炉时，可用红外线测温仪来进行钢材表面温度检测，但因钢材表面存在氧化层，也影响钢材温度检测精度。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
