查询词典 positive pole

Normal working hours, B2-B1 between the need to add a positive voltage, E-B1 between the PN junction forward biased if the Canadian single-junction transistors that turn, after turn-on, E-B1 between the resistance will soon be reduced, to B2-B1 between the current rapid increase in current increase, so that the resistance between the E-B1 further reduced, so the formation of a strong positive feedback.

正常工作时，B2—B1间需加正电压，E—B1间的 PN结若加正向偏置，单结晶体管即导通，导通后，E—B1间的电阻会很快降低，使B2—B1间的电流迅速增加，电流的增加，又使E—B1间的电阻更进一步的减小，如此形成了强烈的正反馈。

Further, we introduce the concept of partially symmetric positive solution and discuss the existence of three partially symmetric positive solutions for the boundary value problem of second-order functional differential equation.

进一步，我们引入了部分对称正解的概念，并讨论了二阶泛函微分方程边值问题的三个部分对称正解的存在性。

提出了一种新的实时检测基波正序分量、基波负序分量和谐波分量的方法，该方法首先将三相瞬时值合成一个空间矢量，然后对所得矢量的实部和虚部分别进行滤波以滤去谐波分量。

A novel non-positive fundamental sequence voltage and current detecting method is presented based on analyzing the function of trigonometric function in detecting the fundamental positive sequence voltage and current.

针对此问题，本文在分析三角函数提取基波电压电流成分有关信息的基础上，提出了一种检测UPQC电压电流信号的新方法。

The same results were observed in the brain of the unilateral pyramidotomy group above the level of the transection site. Below the level of the transection site, the BDA positive fibers were seen in the right pyramid of medulla oblongata and the left dorsal funiculus of spinal cord, but the BDA positive fibers in the left pyramid of medulla oblongata and the right dorsal funiculus of spinal cord were not seen.

锥体束横断损伤大鼠在损伤部位以上可见双侧对称的BDA阳性纤维束，损伤平面以下在右侧延髓锥体和左侧脊髓后索中见有BDA阳性纤维束，损伤侧锥体和右侧脊髓后索中未见有BDA阳性纤维束。

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 soil had great population of bacteria, but the fungi quantity is excessive which may cause the multiplication of germina. As base-fertilizer, the slowed-release fatty had positive influence on soil fast-effect nutrient, but the organism quality is small, the soil enzyme activity with microorganism activity both low. Soil EC, total nitrogen, available nitrogen, available phosphorus and organic matters were significantly negative related to the soil pH. Soil total nitrogen was positive significantly related to soil available nutrient.

土壤中pH值与土壤EC值、土壤全氮、速效氮、速效磷、有机质含量呈显著负相关，土壤全氮含量与土壤速效养分含量有极显著正相关关系，而且土壤有机质含量与土壤速效养分之间也有相互促进的作用，所以土壤养分的平衡效果非常重要，有机肥处理后土壤养分全面，肥力较高。

Among 55 cases with positive PCR, 27 were Gram-positive and 28 were Gram-negative species by reverse hybridization.

对55份PCR阳性标本进一步进行反相杂交，显示G＋菌27份，G－菌28份，其结果与血培养结果相符。

Similarly, a previous gram-positive case did not reduce severity of a second or third gram-positive case.

同样，前革兰氏阳性案例并未减少严重的第二次或第三次革兰氏阳性案例。

In a similar manner, the positive object creates an attractive gravitational field toward the positive mass.

同样，正物质对正质量产生一个引力场。

You can buy sweetened beverages, if that suits you.

你若喜欢的话，可以买些含有糖精的混合饮料。
