查询词典 thresholds

By means of the semigroup theory, spectrum theory, positive cone theory, integrated equation theory and optimal control theory, we obtain the existence of thresholds of these models, the existence and stability of the infection- free equilibrium and the endemic steady state, and the existence of optimal vaccination strategies, etc.

运用泛函分析中的半群理论、谱理论、正锥理论以及积分方程理论和最优控制理论，系统地研究了这些模型的阈值的存在性，无病平衡态和地方病平衡态的存在性和稳定性，最优接种疫苗策略的存在性等。

The thresholds are dynamically adjusted according to the difference between the target bit rate and actual bit rate. This method can reduce the bit rate of intra coded frames while still maintating error robustness and limiting temporal propagation of errors.

该方法根据目标比特率和实际比特率的差值，动态地调整阈值，从而有效地减少了帧内编码的比特率，保持了对差错的鲁棒性，限制了差错的时间传播。

"She saw the children of the settlement, on the grassy margin of the street, or at the domestic thresholds, disporting themselves in such grim fashion as the Puritanic nurture would permit;"

珠儿看到过这块殖民地上的小孩子们，在路边的草地上或是在自家门前，做着请教徒童规所允许的种种怪里怪气的游戏

She saw the children of the settlement, on the grassy margin of the street, or at the domestic thresholds, disporting themselves in such grim fashion as the Puritanic nurture would permit; playing at going to church, perchance; or at scourging Quakers; or taking scalps in a sham-fight with the Indians; or scaring one another with freaks of imitative witchcraft.

珠儿看到过这块殖民地上的小孩子们，在路边的草地上或是在自家门前，做着请教徒童规所允许的种种怪里怪气的游戏：有时装作一起去教堂，或是拷问教友派的教徒，或是玩同印第安人打仗和剥头皮的把戏，或是模仿巫术的怪样互相吓唬。

While from fault detection aspect this method can detect abrupt and incipient faults effectively and is more robust than the methods where the thresholds are determined by statistical properties of residual errors.

第二类问题为在状态空间模型下带有未知但有界噪声的非线性离散时间系统传感器故障的检测与隔离问题。

Most evidence suggests that this process can only occur when the soil is saturated and transpiration is low, but the critical thresholds at which root pressure is inhibited have not been established experimentally.

大多数的证据意味着当土壤是饱和的，而且散发是低点的时候，这一个程序才能发生，但是紧要关头的门槛在哪一个根压力被禁止还没有被实验式地建立。

We calculate the positions and the widths of 21 2P 0 resonances in BeⅡ between 1 1S 0 and 2 1P thresholds with a saddle point complex rotation method.

利用鞍点复转动的方法，计算了21个位于BeⅡ的11S和21P阈值之间的2P0自电离态，得到了包括相对论修正和质量极化修正在内的共振能量和宽度。

Methods A comprehensive method was used for the determination of Comet head center based on gradually increased thresholds in sequential Particle Analysis of Scion Image.

实验方法在对图像分析错误的改进中，本研究采用了以梯度阈值为基础的综合性彗星头中心点确定方法，代替原来计算彗星头中心的固定阈值(80％)方法。

An important property of the ROC of the globally optimized fusion system is obtained, that is, the slope of a curve in the ROC at a particular point can be used to determine the decision thresholds at fusion center and all the sensors required to achieve the detection and false alarm probabilities of that point.

5推导出了全局最优化融合系统工作特性曲线的一个重要性质，即根据融合系统检测概率对虚警概率的导数，可以确定使融合系统工作在该工作点所需的融合中心及各部传感器的判决门限。该性质是对单传感器检测系统ROC曲线性质的重要推广，从而丰富了检测融合理论的研究成果。

The array covers geometrically 85%90% of the 4π solid angle with low detection thresholds.

总立体角覆盖约全空间的85%90%，以及有一个很低的能量探测阈。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
