Using methanol as solvent and sodium methanol standard solution as titrant,the certification of NTO standard substance was investigated by non-aqueous titration .

以甲醇为溶剂，采用甲醇钠溶液作为滴定剂，通过非水滴定法对NTO的定值方法进行研究，选择了最佳条件。

The titrant is a mixture of EDTA and sodium fluoride, both mercury film electrode and fluorinion selective electrode are inserted in the titration solution. In a process of titration, both the added volume of titrant and the concentration of mercury ion at each titration point can be obtained simultaneously from the potentials of two electrodes, and then the concentration of each component in the alloy can be obtained from the titration curves by multivariate calibration.

用ED-TA与氟化钠的混合溶液作为滴定剂，被滴定液中同时插入了汞膜电极和氟离子选择电极，在滴定过程中的任一滴定点，溶液中汞离子的浓度和滴定剂的加入体积可由两个电极的电位测定值同时获得，从而可应用多元校正法由相应的滴定曲线求得混合金属中每一种组分的含量。

The nest materials, pH values, and soil compactions were measured respectively in 4 kinds of nest sites different in surface soil composition, and the process of nesting was observed continuously in fixed points.

共调查统计5 148个蜂巢的筑巢场所和朝向；选择4个土壤表层成分不同的筑巢地，分别测定其筑巢沙土的机械组成、pH值和土壤紧实度；定点连续观察整个筑巢过程。

To further verify the rationality and science of the evaluation system and find out its limitation, the thesis takes the northwestern mountainous and hilly towns in Hangzhou for example, chooses evaluation indices, defines weight distribution, assigns values to the indices, constructs the evaluation system, evaluates the land constructability and defines four subareas for the northwestern mountainous and hilly towns in Hangzhou depending on the constructability, which refer to prohibition area, regulation area, constructable area and build-up area.

为了进一步从实践上验证该评价体系的合理性和科学性，以及校验其存在的不足之处，本文以杭州市西北山地丘陵城镇为实例，选择评价指标，进行权重分配和指标赋值，构建评价体系；进行土地适建性评价；界定杭州市西北部山地丘陵城镇的建设适宜度分区——禁建区、限建区、适建区和已建区。

In this proposed algorithm, all focal elements of every piece of evidence are classified into dereliction and remainder, and the basic probability assignments of those derelictions are reassigned to the remainders when they are correlative or the dereliction is nested to the remainder.

该算法以焦元的能量函数、证据的平均能量函数作为选择抛弃焦元和剩余焦元的标准，同时将抛弃焦元的基本概率赋值重新分配给与之具有嵌套关系或相交关系的剩余焦元。

The embeddable points are selected according to their curvatures firstly, and then the binary watermark image is divided into two parts, respectively, for spatial and frequency insertion.

根据曲率选择合适的嵌入点，将二值水印图像化分成两部分，分别嵌入到待嵌入点的空间域和变换域。

The basic idea is to have an environment to easily train many neural networks in parallel,initialised with different weights, parameters or different architectures, so the user can find the best NN simply by selecting the fittest neural network after the training process.

最基本的方法是有一个环境，它能容易的训练许多神经网络，它们是平行的，以不同的权值。参数。或者不同的结构体系，这样一来用户就可以在训练过程结束以后简单的通过选择最合适的神经网络来得到最佳的。

Nameplate rating is only a guide to transformer application, AND should only be used as a first step in the selection process.

铭牌额定值仅是变压器应用的一个指导，只是选择过程的第一步。

Nameplate rating is only a guide to transformer application, and should only be used as a first step in the selection process.

铭牌额定值仅是变压器应用的一个指导，只是选择过程的第一步。这无疑是摆脱混乱与愚昧的第一步。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
