Another trend apparent throughout the tribe is the reduction of the large, terminal inflorescence to a few digitate or paired racemes, often arising from the axils of specialized leaves with inflated sheaths and reduced blades. In the most complex genera the ultimate unit is a boat-shaped sheath without a blade subtending 1 or 2 short racemes, and by repeated branching many of these units are gathered into a leafy compound panicle.The spikelets contain 2 florets, but this is not obvious as the florets are delicate and usually reduced.
Another趋势对一些指状的或的大,顶生的开花的减少配对总状花序,在最多复合体属里末级的单位是一舟状的没有一叶片对着1或2短总状花序的鞘,并且通过被重复的分枝大多数这些件被收集成为一多叶的复合的panicle。

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。

In the second place, this paper uses the financial data reported by China's private listed companies and statistical analysis skills to test the theories and hypotheses. The research collects all required data from 2000 to 2002, examines the profit ability, the gain ability, the repay ability, and the cost control ability for all sampling listed companies by using Paired-Samples T test in the quantitative analysis section. The results show that these listed companies'profit decreases, income increases, repay ability enhances after the companies go public. Finally the paper takes the non-operating expenses as the illustrating index for the cost control capability of the companies to demonstrate that there is an obvious increase of non-operating expenses after getting great amount of money in IPO, in this sense it can be stated that there is the intendancy of low capital utility rate in private companies.
研究选用了描述性统计分析方法对样本企业IPO前后时段的财务指标进行了对比考查,并运用配对样本t检验方法进行了显著性检验,研究结果表明民营企业在IPO前后的盈利水平总体上是显著下降的;同时研究也显示虽然获利水平出现了小幅上升,但这是由于企业通过IPO融资增加了投资规模导致的;企业的偿债能力在IPO之后有明显的好转;研究最后以营业外支出作为企业成本控制能力的解释指标,发现企业在IPO上市融得大量资金后对主营业务以外的支出有明显的增多,可以判断民营企业存在资本利用效率低下的现象。

The authors proposed that heterochromatin change in genome might play an important role in balancing the germplasms between maize and its distant relatve after cross and parthenocarpy.
这种变异不仅存在于表型不稳定的早代孤雌系中,而且还存在于表型稳定的高代系中,造成这种变异的原因可能是因为远缘种质的引入影响到遗传平衡进而引起染色体发生结构重排并引起染色质的变化,这种变化与玉米染色体组中非同源染色体间存在的同源片段和因此造成的减数分裂过程中非同源染色体配对有着直接的关系。

Leaves 3 or 4(–8) per ultimate branch; sheath densely deciduously setose; auricles readily deciduous, falcate; oral setae radiate, purple, ca. 3 mm; ligule prominent, ca. 5 mm; blade lanceolate, 10–23 ×(1–)2.5–3.3 cm, secondary veins 7- or 8-paired, abaxially yellow-green and white tomentellate, adaxially light green and glabrous, base asymmetrically cuneate, margins serrulate.

Second, residues in the reactive site of the inhibitor were replaced by the consensus substrate recognition sequence of furin, namely, Arg at P_1, Lys at P_2, Arg at P_4 and Arg at P_6. In addition, the P_7 residue Asp was substituted with Ala to avoid possible electrostatic interference with furin inhibition. Finally, the extra N and C terminal residues beyond the doubly conjugated disulfide loops were further truncated. However, all resultant synthetic peptides were found to be temporary inhibitors of furin and kexin during a prolonged incubation, with the scissile peptide bond between P1 and P'1 cleaved to different extents by the enzymes.
高活性、低分子量的furin酶抑制剂有可能发展成为新型的抗细菌内毒素和抗病毒感染的药物,我们以绿豆胰蛋白酶抑制剂Lys片段长链22肽为模板,设计了一系列能抑制furin和kexin活性的突变体,采用如下三种方法逐步优化:一、去除Lys片段长链三对二硫键中的一对,用Ser替换Cys,减少可能存在的二硫键错误配对;二、抑制剂的活性中心根据furin底物的专一性逐步改变,即P1、P2、P4和P6位分别变为Arg、Lys、Arg和Arg,同时为了避免P7 Asp和P6 Arg之间可能存在的相互作用,将P7位Asp替换为Ala;三、将两对二硫键形成的双环的外面5个氨基酸残基去除。

The major findings are:⑴During the intelligence test for the three groups of students, for half of the students or most of the students their scores on the all-including scale, the language scale and the performance scale all increased to various degrees;⑵From the analysis of the relationship between intelligence and reaction time, it is found that the result of this study confirms the existing views that there is a negative correlation between intelligence and reaction time, and the negative correlation is more evident when it is choice reaction time;⑶Different motor skills have different influences upon children with lower intelligence. Though the difference is not large, the average increasing percentages in the sample T tests for the three groups before and after the experiment show that the effect of open motor skill is the best, that of the synthetic motor skill or the open-closed is the better, and that there isn't a marked change in the closed motor skill trainees;⑷While analyzing the result of the experiment, it is found that the scores on the performance scale are higher than the scores on the language scale, especially in the open motor skill group, which tells us that the intelligence improving effect of physical training is realized to a greater extent through increasing their performance abililty.
研究结果显示:⑴相对于实验前测试结果,三个实验组学生的智力水平在实验后测试中不论是在全量表得分还是在语言量表、操作量表得分方面均得到了不同程度的提高;⑵从智力与反应时的相关分析可看出,本研究结果进一步验证了前人观点,即智力与反应时有显著的负相关,特别是与选择反应时有很强的负相关性;⑶不同运动技能对智力落后学生智力影响不同,虽然实验后各组间没有显著性差异,但经各组实验前后配对样本T检验及实验前后各项分数均值提高百分率可看出,开放式运动技能组实验效果最好,综合运动技能组次之,闭锁式运动技能组实验前后在智力测验量表得分上无显著性变化;⑷各组实验前后的操作量表分比言语量表分提高幅度更大,开放式运动技能组表现得尤其显著,这表明了体育活动对改善智力落后学生的智力水平,很大程度上是通过提高他们的操作能力来实现的。
