A preliminary study on the number and morphology of chromosomes in Paulownia.

标题 泡桐属植物染色体数目和形态的初步研究。

Preliminary study on the pollen morphology of Paulownia.

Title 泡桐属花粉形态的初步研究。

Although the virus is similar with other isolates in other regions,which have white spot symptom,in morphology,range of host,symptom etc,but it is very different from others in size of virion,distribution in host cell,size of the genome,etc.So,we think that it isa new virus of penaeid shrimp.

虽然该病毒在形态、寄主范围、症状等方面与其它地区分离到的能产生白斑症状的对虾病毒相似，但它在粒体大小、在细胞内的分布、基因组的大小等方面与其它地区的病毒分离物差异很大，属不同种的病毒。

Scanning electroscopy is used for study of the morphology of silk spigots and trichobothrial base in 32 species.

本文较详细地介绍了三科的研究概况、形态特征和地理分布概况，首次利用扫描电镜对10属32种蜘蛛纺器的纺管和听毛窝的细微结构进行观察。

Species had three kinds of diets during the non-breeding season:(1) mainly invertebrates,(2) mainly fruits, and (3) mainly nectar. This study demonstrated that the diets of 14 passerines during the non-breeding season were significantly correlative with tongue morphology (r=0.424, P .05) and were most correlative with brush length and width of the 3/4 position (r=0.62, P.05). For example, Yuhina brunneiceps's primary diet is nectar and it has the brush-tipped tongue with the longest brush length. Niltava vivida mainly forages for fruits and has a tongue with longer width of the 3/4 position.

十七种鸟类在非生殖季时的食性，亦可分为三大类群：（1）主食无脊椎动物；（2）主食果实；（3）主食花蜜。14种鸟类的舌部形态与其非生殖季食性具有显著相关，其中，仅舌分叉长及3/4位置的舌宽与其食性较有关系，可解释非生殖季食性约36%的解释变异量，也就是分叉长较长的舌头属於刷状卷曲舌形，主食花蜜，以冠羽画眉为代表；3/4位置舌宽较大的舌形，主食果实，以黄腹琉璃为代表。

The marine yellowish-green alga (strain PP983), often ellipsoidal, occasionally spherical, 3-4μm long, 2. 5-3μm wide, contains one nucleolus. Morphological features and pigment composition analysis showed that this alga was a new species of the Xanthophyta and was named as Ellipsoidion maratilis Shi et Hu.

从中国东海海域采集并分离得到的一种黄绿色单细胞超微型藻（品系PP983）多为椭球形，少为球形，含一个细胞核，形态观察结合色素分析表明它是黄藻门、柄球藻目、椭球藻属中的一个新种，被定名为海生椭球藻(Ellipsoidion maratilis Shi et Hu，sp.nov。)。

So we should mainly study it in Heilongjiang.,Several methods of identification of resistance to soft rot disease at seedling stage were studied with replicated orthogonal design.

本试验通过软腐病菌形态及生理生化特性对2001年8-10月份在黑龙江省各地采集的大白菜软腐病病样进行分析，结果表明：黑龙江省秋季大白菜软腐病的主要病原菌是欧文氏菌属中的胡萝卜软腐欧文氏菌胡萝卜软腐亚种，因此，我省在进行软腐病研究时，应该主要以该菌为主。

The results of dendrogam were consistent with the previous conclusion of morphologic classification and cytotaxonomy, and suggested RAPD was suitable for analysis of phylogenetic relationships among species of Oxya .

聚类图所呈现的种间关系与传统的形态及细胞分类学结果基本一致，5种稻蝗亲缘关系的远近程度得以清楚显示，说明RAPD技术在稻蝗属种间分子系统学研究中具有很好的适用性。

Life. But the intrinsic way of the Internet by wire confines accessing and using of the network information.

然而，Internet固有的有线连接方式大大限制了人们对网络信息的访问和使用。

I have a strong persuasion that this is true .

我坚信这是正确的。
