Meiotic pachytene bivalents were obtained from porcine testes using prolonged hypotonic treatment combined with high chloroform Carnory's fixative solution. Mitotic metaphase chromosomes were prepared from blood cell culture. Comparative studies on division index and length of pachytene bivalents and mitosis metaphase chromosomes showed that those of the former are 5 times higher and 3.42(1.87～5.98) times longer than the latter, respectively. Chromomere maps of bivalents are more abundant than mitotic metaphase G-bands, while they are correspondent with mitotic early-metaphase G-bands. The result was found by using the chromosome 12 as a sample.

以性成熟公猪睾丸和外周血为材料，采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体，通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究，发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87～5.98)；同时以12号染色体为例，比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带，表明染色粒结构带比中期染色体G-带带纹丰富，而与早中期G-带带纹吻合。

Substitute teacher is our primary school principals, he is a very old man's Bugouyanxiao that he had a double eagle eye, often on the natural course of my time on the very nature, I do not like this so I stifled the atmosphere, there is a very old man in particular Habits, with his glasses, I do not know if the old flowers or short-sighted glasses, not all the glasses on the bridge of the nose through the glasses with a man he did not, his eyes with a sharp nose, the man's time Head, above the framed glasses from the preview, this action has been very much afraid of me, the more quiet at a time when I knew that he would not issue a noise, and then the eagle eyes of my immediate aim, and then we all turned to see me ...... And for a long time ago, more and more like I do not like him, and he would seem to have any grudges against me more and more quickly verify my guess.

代课老师是我们的小学校长，他是一个很不苟言笑的老头子，他有一双鹰的眼睛，每每上自然课的时候我就很不自然，我不喜欢这个让我窒息的气氛，老头子有一个很特别的习惯，他带着的眼镜，不知道是老花还是近视的眼镜，不像大家把眼镜带着鼻梁上透过眼镜看人，他不，他把眼睛带着鼻子尖上，看人的时候低着头，从眼镜框子的上面瞄，这样的动作让我一直很惧怕，越在安静的时候我会发出不自知的噪音，然后鹰的眼睛马上就瞄准了我，然后大家都会扭头看我……久而之久，我好像越来越不喜欢他，他也好像也越来越跟我有仇，很快就验证了我的猜想。

The results showed that the total dissoluble proteins hands of 8% and 10% gel were 91 and 97, respectively, and the seed salt soluble proteins bands of 10% gel were 69; All of the five alfalfa species have their own characteristic bands, which are different in number, distribution, width, and concentration; Among three methods, the five species' seed dissoluble protein fingerprints of 10% gel' bands is relatively more, which genetic diversity scattered in A, B and C regions, and can be repeated in different experiments. So it's the best fingerprint. The fingerprints of the seed dissoluble proteins and seed salt soluble proteins of five species are unanimous, which showed that: the hybrid has the nearest genetic distance with Medico go sativa cv.

结果显示：5/个种10%和8%凝胶电泳的种子可溶性蛋白总带数分别为97和91， 10%凝胶电泳的种子盐溶蛋白共有69条谱带；5种苜蓿在种子可溶性蛋白和盐溶蛋白电泳图上都具有各自的特征谱带，谱带数目、位置、宽窄和颜色深浅都存在明显的差异；10%凝胶的可溶性蛋白指纹图谱谱带数目相对较多，种间遗传差异在A、B、C区均有分布，谱带的重复性好，是鉴别种的最好图谱。5种苜蓿种子可溶性蛋白和盐溶蛋白指纹图谱一致，表明杂交种和敖汉苜蓿的谱带相似性最大。

It is overall a monoclinal structure dipping to south, on which three group faulted structures with the directions of E-W, NEE, and NE-SW are developed, and they are tensional faults. The Orinoco heavy oil belt has been divided into two tectonic zones by one regional fault with the trend of NE in the plane, and the characteristics are different in the two tectonic zones.

奥里诺科重油带是目前世界上唯一一个还基本未开发的大规模重油富集带，它位于东委内瑞拉盆地边缘隆起带，总体是一北倾单斜，其上主要发育E-W向、NEE向和NE-SW向三组断裂，且以张性断裂为主，其中有一条北东向区域性大断裂将奥里诺科重油带在平面上划分为两大构造区，其各自的构造特征不同。

我们曾经介绍过一种荧光R显带的方法［10］，在此基础上建立了一种在显带染色体上直接观察杂交信号的新的定位方法：在细胞培养时，同时加入BUdR和Hoechst33258，PI染色后即呈现清晰的荧光R带带型，用彩色和全色黑白胶卷照相均可得到满意的结果，尤其适用于国内具有一般条件的实验室。

Pathologic characteristic of supraglottic carcinoma spreading anterosuperiorly in l00 cas-es was investigated by whole-organ sections of the larynx. The results showed that 75%of supraglottic carcinomas were found to spread anterosuperiorly.In these cases, carcinoma in the epiglottis-ventricular fold accounted for 90%;epiglottic carcinoma 8l.8%; and carcinoma in the ventricular fold 33.3%.
