查询词典 the positive

In this thesis, we use the Min-Max criterion and Parks-McClellan algorithm to design this optimal approximation error of spectrum. Moreover, we give constraint of this optimal spectrum to get the positive spectrum. Then the positive spectrum can be factored by Spectrum Factorization Theorem and can be realized by FIR system.

我们利用最小化最大误差指标，及Parks-McClellan演算法，设计出具有最佳误差的频谱，并对此频谱做限制式上的处理，来得到正数列频谱，并将所得到之正数列频谱利用分解理论做分解，并以FIR系统实现之。

In ovary, PNA receptors appeared in the oocyte cytoplasm of second phases of oogenesis; the positive granules gradually increased from third to forth phases, and they exhibit a maximum expression before vitellogennic stage in cytoplasm of oocyte; from vitellogennic stage to chorionation stage, the positive granules gradually reduced. Binding sites on follicle cells were changed with their morphological variation in every stage of oogenesis.The staged and specific expression of oncogene c-kit, the tyrosine-kinase receptor, is closely related with gametogenesis.

2在中华蚱蜢卵子发生的早期，PNA受体是由卵母细胞自身合成；在卵黄发生前的准备时期，卵母细胞质中的PNA受体一部分来源于自身合成，另一部分则来源于滤泡细胞，而糖复合物的大量出现可能直接与卵黄发生有关；卵黄发生期PNA受体的减少可能是在卵黄物质形成中部分发生了修饰；卵黄和卵壳的相继形成过程中，阳性反应的出现说明PNA受体参与了卵黄膜及卵壳的形成，而这些受体物质是由滤泡细胞分泌的。

The results showed that the positive rates of RNA integrity in grind with liquid nitrogen group and in homogenizer without liquid nitrogen group were 68.42% and 29.79% respectively, and there was significant difference between these two groups; however, there was no statistic difference in positive rate of RNA integrity, OD260/OD280 ratio and 3-actin gene expression level between the drug-induced labor group and non-drug induced labor group.

结果发现，液氮研磨组分离完整RNA的阳性率高於匀浆器处理组，分别为68.42%和29.29%，两组比较有显著性差异；药物引产组及非药物引产组在分离完整RNA阳性率、胚胎组织RNA的OD260/OD280比值和胚胎组织β-actin基因表达量上均无统计学差异。

In this paper, we used the regularization method and the best disturbed iteration to solve such more extensive equations: every kind of positive problems and inverse problems of the hyperbolic partial differential equation and parabolic equation. We give homologous methods to solve the positive problems and inverse problems of nonlinear Burgers equation and Boussinesq equation.

本文应用正则化方法和最佳摄动量法，解决了一类更广泛的双曲型和抛物型偏微分方程的各类正问题及反问题，对非线性的Burgers方程及Boussinesq方程的正问题及反问题，也给出了相应的求解方法。

The positive fact is an aggregate that includes some elements about the affairs composed,an informatory point in the fourth—dimension while the negative fact is an empty aggregate that includes nothing,a supplementary aggregate of any positive fact.

积极事实是一个包含事实构成要素的集合，在四维时空坐标中对应的是一个确切的点；而消极事实是一个不包含任何元素的空集，是任何一个积极事实的补集。每一积极事实都对应着无数消极事实。

objective to summarize the positive rate of choledocho lith with abdomen ultrasound and analyse the related factors to effect positive rate,so we can raise some further measures to improve the veracity of ultrasound diagnosis.

目的：总结经腹超声诊断胆总管结石的阳性率，分析影响阳性率的相关因素，并提出进一步的改进措施，以提高超声诊断胆总管结石的准确率。

Directed against the designed parallel welding head mechanism of IC chip pasting machine,the movement equation was established,the positive solution of motion equation was presented,and the positive and reverse solutions of velocity and acceleration were derived.

高速高精度IC芯片粘片机是IC芯片封装的主要设备之一，其粘片速度已超过10 000次/h，定位精度达微米级，而且粘片速度和定位精度有越来越高的趋势[1]，但目前国内外IC芯片粘片机的焊头机构都采用串联结构的形式，运动部件的惯量很大，不利于粘片速度和定位精度的提高。

The CNTF and FGF2 positive cell number and the positive area percentage, as well as the number of neuron and neuroglia calculated by immunofluorescence analysis in the spinal cord.

将嗅鞘细胞移植入脊髓半横断SD大鼠，观察术后7天和21天嗅鞘细胞在脊髓内的存活情况，并对脊髓组织切片进行CNTF和FGF2免疫荧光组织化学染色，计数阳性细胞并计算阳性面积百分比。

The results show that corresponding to the positive / negative phase of interdecadal modes of the North Pacific SST, the anomalous patterns of the atmospheric circulation and climate in positive phase are opposite to that in negative phase, it indicates an important impact of these interdec...

其结果极为清楚地表明，对应北太平洋SST的年代际模的正、负位相，大气环流和气候异常的形势都近乎相反，充分说明SST年代际模的重要作用；由于北太平洋SST的两个年代际模有十分相近的水平结构特征，它们对大气环流和气候的影响也有十分相似的特征；北太平洋海温年代际模对大气环流的影响在中高纬度地区呈正压结构特征，而在热带地区的响应主要有斜压结构特征。

To make the service people be more willing to provide good service, the service marketing of nonprofit organization should be combined with the positive mission and politesse besides 3P, so the people, physical evidence, process, positive mission and politesse (5Ps) would be a package of excellent service marketing strategies in nonprofit organizational setting.
