By Giemsa--C technique, the chromosomes of Aegilops tauschii (85A-34) and Hordeum vulgare (H2) and Ae.tauschii- H.vulgare amphidiploid were all produced clear bands, the terminal band, centromeric band, secondary constrition band and rich intercalary bands were displayed distinctly, thus the corresponding Giemsa-C banding patterns were confirmed.

In our research on study chemical reaction of active methylene compounds and brom-acetophenone. Because of brom-acetophenone is compound that contain carbonyl and halogen ,which will take place electrophilic substitution and nucleophilic addition. When active methylene compounds are ethyl acetoacetate and β-diketone, controlling reaction condition, we have found that mono-substitution's production and di-substitution's. production is isolated; active methylene compounds are acetoacetanilide and acetoacetanilide derivate, pyrrolidin-2-one derivants were obtained by substitution and close-ring reaction .but there is no report about it.

本文是让活泼亚甲基类化合物与溴代苯乙酮发生化学反应，由于溴代苯乙酮是含有羰基的卤代烃结构，它可以发生亲电取代和亲核加成反应，当活泼亚甲基类化合物为乙酰乙酸乙酯和β-二酮时，控制反应条件可以发生单取代和双取代两种产物；当活泼亚甲基类化合物为乙酰乙酰芳胺类化合物来反应时，溴代苯乙酮中的羰基与氨基会发生分子内的关环反应生成吡咯烷-2-酮衍生物，这在以前的研究中是没有发现的。

In the process of our analysis,the non-sequential double ionization rate, two-electron ionization energy, two-electron momentum correlation and the combined potential of Coulomb field and laser field are calculated with the molecular internuclear distance changing.

我们分别计算了非时序双电离率、两电子的电离能、两电子的动量相关、库仑场和激光场的复合势随分子核间距的变化关系。

These Fos-immunopositive neurons were intensively distributed in different subnuclei of the vestibular nucleus complex (including medial, superior and spinal nuclei), nucleus of the solitary tract, locus coeruleus, medial and lateral parabrachial nucleus of the brainstem, paraventricular nucleus of the diencephalons and the amygdala of the limbic system;(3) The expression of Fos protein can be scarcely detected around forementioned regions in brains of the rats following complex two-axes rotation stimulation after the bilateral labyrinthectomy.

结果显示：(1)正常对照组和双侧迷路毁损组大鼠的脑内均未检测到Fos样免疫阳性产物；(2)两轴旋转刺激组的大鼠在给予复杂的围绕两轴旋转的加速度刺激后，在大鼠脑和脑干的多个核团内均可检测到Fos样免疫阳性神经元，其阳性产物主要表达于细胞核。

Once nucleate boiling is initiated, heat transfer in propanol/water mixtures was shown to becontrolled mainly by the mass diffusion effect. In the concentration range studied in this work, the addition of SDS in water results in insignificant variation of dynamic contact angles.

沸腾一旦起始后，正丙醇水溶液比纯水的核沸腾热传速率小，此一组成的影响与双成分混合物的汽-液平衡和热、质传的物理特性有关，可以质量扩散效应描述。

Puna Chicory, leymus multicaulis and Psathyrostachysjuncea.For the materials used in this article were some old seeds which had been stored for 3-7 years, we found a lot of abnormal mitotic and meiotic cells, such as chromosome bridge. chromosome laggard, micronucleus, multipolar division and so on. Moreover, we also found the wheat"s multi-anther, double germinate-hole"s microspore and collected the photos of every period of meiosis. mitosis.

因为用于细胞学检测的小麦材料是搁置多年的陈旧种子，所以在检测染色体数目时，发现大量异常分裂现象，包括染色体桥、染色体落后、微核、多极分裂等；实验过程中还发现小麦多花药现象和花粉粒具双萌发孔的现象；同时在显微观察同时还注意搜集了细胞有丝分裂、减数分裂各个时期的分裂相图片。

The vascular bundle of stem is the type of double phloem. The anther is tetrasporangiate. Simultaneous cytokinesis in the microspore mother cell follows meriosis.

The heat insulation materials of the XPS of which decrease embankment height, thermal pipes setup in sun-facing side of embankment, crushed rock cover and shading board are used to adjust the subgrade damages caused by the thaw basin. Crushed rock-based embankment and both sides thermal pipes are used to adapted to subgrade damages caused by thaw-sandwich layer. The berms are adapted to subgrade damages caused by the frozen bulge.
