It was also found that the chromosomes paired well and formed a rod heteromorphic bivalent in the hybrid F1[73(36)9-1×CSDT 1BL]. Whereas 73(36)9-1 produced mainly configuration of 20''+1'+t' when test-crossed with CSDT 1BS. It showed that the translocation occurred on chromosome 1B short arm, and this segment came from rye chromosome 1RL. In the present paper we discussed also the way in which the translocation might be caused, and concluded that it was formed through reunion of two kind telocentrica (1BL and 1RL) after simultaneous misdivision of two univalent chromosomes (a wheat chromosome 1B, and a rye 1R).

同时还发现，73（36）9-1和"中国春"双端体的1BL能很好地配对并形成一个棒状的异形二价体，而它和CSDT 1BS的染色体则主要产生20+1′+t′的构型，从而证明易位发生的可能途径，推断是由于在F1花粉母细胞中的两个单价体（一个是小麦染色体1B，一个是黑麦染色体1R）同时进行错分裂之后产生的两种端着丝点染色体（1BL和1RL）重新并合形成的，因而冬小麦73（36）9-1可能是一个自发产生的易位系。

Ciliata consists of two elements, the robust and short filamentous chloronema which is composed of 4~6 oblate cells and the thin and long caulonema like osier on which there are many clavae of 2~5 cells.

Sinense, the spores germinate inside their exospores and then divide into massive protonemata;the massive protonemata can form two kinds of protonemata of which one is clubbed protonema with papillae,and the other is caulonema composed of long and cylindrical cells ; the gametophyte archaeocytes only occur on the massive protonemata.

结果表明：中华缩叶藓的孢子在壁内萌发，随后分裂产生块状原丝体；块状原丝体上可产生两种丝状体，一种是具疣的棒状原丝体，另一种是由长圆柱状细胞组成的轴丝体；配子体原始细胞只产生于块状原丝体上。

The result showed that the plant of Maicao No. 9 was tall, with good fecundity, fully filled grain and vigorous growth. The chromosome number of the root cells was 2n=56, through the observation of pollen mother cells meiosis, there were a certain amount of univalents, ring bivalents and bar bivalents in PMCM. Different numbers of lagging chromosomes, chromosome bridges and micronucleus were found in anaphaseⅠ, anaphaseⅡ and tetraspore.

结果表明：麦草9号植株高大，结实性较好，籽粒饱满，生长旺盛；根尖细胞染色体数目为2n=56，对其进行花粉母细胞减数分裂观察，中期Ⅰ具有一定数量的单价体、环状二价体、棒状二价体；后期Ⅰ、后期Ⅱ与四分体时期都出现不同数量的落后染色体、染色体桥、微核等现象。

The results show that upper bainite of 9Cr2Mo Steel and GCr15 steel is feathery and the upper bainite carbide is lamellar or claviform. The upper bainite carbide distributes between the subunits of bainite ferrites by and large parallelly to the axis of bainite ferrites. Lower bainite of 9Cr2Mo Steel and GCr15 steel is in bamboo leaf shape and the lower bainite carbide is in shred or fibre shape. The lower bainite carbide distributes between the bainite ferrites, furthermore, the angles between lower bainite carbonide and the principal axis of the lower bainite ferrites are unequal.

结果表明，9Cr2Mo钢和GCr15钢的上贝氏体组织呈羽毛状，上贝氏体碳化物呈长短不一的薄片状或短棒状，分布在铁素体亚片条或亚单元之间，其排列与贝氏体铁素体片条轴向大体上平行分布；下贝氏体组织呈竹叶状或针状，下贝氏体碳化物呈细片状或纤维状等形状，分布在铁素体片中间，大多数与片条的主轴方向交角排列，但角度不等。

Objective To reveal the transcription profile of PfRON4 gene in Plasmodium falciparum erythrocytic stage. Methods P.

摘要目的分析恶性疟原虫棒状体颈部蛋白4基因（PfRON4）在红内期不同发育阶段的转录水平。

EAA formed a rodlike extension structure in PP matrix, and much more continuous structure are formed, which resulted in a rapid decreasing of the volume resistivity with the increasing of EAA resin content.

EAA相在PP基体中呈棒状伸长结构，且随着EAA树脂含量的增大，在PP基体中形成更多更为连续的棒状伸长结构，使体积电阻率迅速下降。

The main component of WPB is von Willebrand factor, whose expression and tubulation are necessary for the formation of the unique rod-like WPBs. Different molecules such as vWF, P-selectin, CD63, Rab27A and Rab3D are recruited into WPB mediated by the AP-1, AP-3 or other transport machinery.

血管假性血友病因子(von Willebrand Factor， vWF)作为该细胞器的主要组成分子，其多聚体以管状形式在WPB中规则排列，促使WPB独特的棒状形态的形成。

Under normal temperature (25-30℃), the process of pollen mother cell meiosis is normal; The most of chromosomes become bivalents which like "V","O","Y","X", sticks and dots, and mainly like dots,"V" and "O"; and a few of univalent (0.79% of Tainong 1 and 0 of Irwin) and multivalent (4.76% of Tainong 1 and 3.57% of Irwin) had been observed.
