偶线

By electromagnetic theory, for the case that the magnetic dipole source and the receiver are set in seawater, the general expressions of frequency_domain electromagnetic responses for a layered benthal model are deduced. From those, the transient response expressions of three common configurations—vertical magnetic dipole_dipole, central loop, and coincident loop, located on the surface of uniform half_space seafloor, are derived respectively, supposing that seawater is uniform half space, or its depth is finite.

根据电磁场理论，推导了磁偶源和接收点均位于海水中时层状海底模型的频域电磁场响应一般表达式，并通过此式，得到了海水为均匀半空间和有限海水深度两种情况下，垂直磁偶极装置、中心回线和重叠回线分别置于均匀半空间海底表面时的瞬变电磁响应表达式。

In this paper,the author obtains some features of Bertrand curves such as that necessary and sufficient conditions for a Bertrand curve is curve,discusses the distance from a point of a Bertrand curve to the corresponding point of the mate of Γ,the angle of the two tangent lines and so on.

In Peiai 64S, the microtubules showed abnormal patterns of distribution from pre_meiotic interphase to metaphase Ⅰ. For example the broad band of perinuclear microtubules seen at diakinesis in IR36 was much disorganized and loosened in Peiai 64S.

(1)在偶线期具极性分布的微管分布不存在；(2 )在小孢子母细胞减数分裂期间的细胞内出现许多特别粗的微管束；(3)在终变期围绕核的微管宽带结构松散及内含微管密度低。

The karyotype of Nelumbo nucifera during meiosis zygotene was established in this study,which would help the studies of meiosis and molecular cytogenetics in lotus.

本研究建立了中国莲偶线期染色体的核型，为研究莲的减数分裂过程及分子细胞遗传学研究提供基础。

Zygotene is characterized by the active and specific pairing of homologous chromosomes leading to the formation of a haploid number of bivalents.

偶线期时，以同源染色体活跃的、特定的配对为特征，形成了单倍数的二价染色体。

All-line phase is also called zygotene.

合线期又称偶线期。

Zygotene nodules and development of the brown ratRattus norvegicus caracohave been studied, by surface spresding with SDS treatment, silver and phosphotungatic acid staining techniques.

采用表面铺展－SDS处理、硝酸银和磷钨酸(Phosphotungstic acid，PTA)染色电镜技术，研究了褐家鼠精母细胞中常染色体联会复合体（Synaptonemal complex， SC）的发育及偶线期节（Zygotene nodule， ZN）。

When the field is applied along the wires, the hysteresis loop exhibits a shear effect, which always means an equivalent demagnetizing field. It comes from the dipole interaction between the wires. The coercivity of the Fe nanowire arrays in the diameter of 16nm is 2000Oe at 300K, and it will increase to 2800Oe when the temperature decreases to 5K.

不同直径的Fe纳米线的磁滞回线均表明沿着线的方向均表现出shearing effect，表明其中存在一个等效退磁场，它来源于线间的偶极相互作用。16m的Fe纳米线的矫顽力室温下为2000Oe，5K时则达到2800Oe。

Eight-direction Line Diagram is formed by The Thirteen Postures, including eight directions, four normal directions of martial arts: east, west, south, north, and four corners directions: northeast, northwest, southeast, southwest, combining with five steps: advancing, retreating, look to the left, look to the right, central equilibrium, The circular Eight-direction Line Diagram is from a square, forming from the rim of a circle through geometry principle.

八方线图是从武术方向方位的四正位：东、西、南、北，四偶位：东北、西北、东南、西南、及前进、后退、左顾、右盼、中定等八门五步十三势组成，用几何原理以外接园从正方变化为圆形八方线图。太极拳十分重视方向方位及中正安舒，有了八方线，在练拳时，有一个准确的中心点，方向方位准确无误，避免脚步下出现&差之毫厘，谬以千里&的错误。

Thermoelectric EMF of 42 pVPC for the standard "Alloy 180" Nichrome junction of an ordinary wirewound resistor. If a resistor is chosen with the copper nichrome junction the value is 2.5 pVPC.
