Longitudinal root sections of the wild type and the gls mutant cultured in nutrient solution for 4 days showed that biosynthesis and distribution of amyloplast in the columella cells of gls were normal as compared with the wild type, suggesting that root gravitropism loss in gls mutant is not caused by the defect in amyloplast sedimentation, but possibly by the disturbance of auxin transport and distributation.
4天龄的根系纵切片结果显示:突变体gls根尖结构完整,根尖柱细胞内淀粉粒的生成和分布正常,表明gls突变体根系向地性的缺失不是由于淀粉体的原因,而可能通过影响生长素运输和分布造成。

The study has shown:(1) With increasing sediment depth and the woody giblets, the total organic carbon, the extraction of benzene , the total humic acids and the unhydrolyte are enhanced, while the hydrolyte is decreasing.(2) According to the GC-MS analysis, n-alkane,n-alkan-2-ones and n-alkanones are composed mainly of long-chains,such a result is thought to be characteristic of a herbaceous input from 2300a.B.P. n-alkanones exist in the samples may be considered as the evidence of microorganisms activity.(3) It is showed that the lipids is more sensitive to the climate change than the floristic. The proxy of the pollen spore of the peat stratum is different from the normal environment proxy. It is one of the main reasons that the sensitivity difference of the bog vegetation reacting to the climate isn't accordant with the log of the fat molecule fossil and biology fossil.(4) The transformation of the peat organic carbon is under the influence of temperature,acidity,organic material constituting, etc, and it showed the up-trend with the depth. In the short-term scale, the conversion of the peat organic carbon is effected by seasonal water,regional climate and vegetations; while in the long-term scale, it is controlled mainly by the climate.(5) According to the comparing the orderliness of organic compound,vegetation giblets with the depth to the characteristics of the peat molecule fossil with the section, in the development of this peatmire, 1500a B.P(210cm)is regard as the borderline of the late Holocene, the keynote of the front period is warm with several cold fluctuations, and the trend of the back period is dry and cold although there were several fluctuations.
研究表明:(1)随深度的增高及植物残体中木本残体的增多,总有机碳、苯萃取物、总腐植酸、不被水解物含量逐渐增高,而易水解物含量减少;(2)GC- MS分析显示,正构烷烃,直链烷基2-酮和正烷醇均以长链组分为主,揭示了该泥炭柱剖面2347a.B.P的母源输入以草本植物为主;甲基酮类和短链正烷醇的存在是微生物活性很大的生物证据;(3)通过有机分子标志物与孢粉、植物残体等指标的对比研究表明:脂类化合物对气候变化的反映要比植物种灵敏得多,不同沼泽植物对气候变化的敏感性的差异是脂类分子化石记录与生物大化石结果很难一致的主要原因之一;(4)泥炭有机碳的转化受到温度、酸度、有机物质组成等很多因素的影响,短时间尺度,泥炭有机碳的转化受季节性降水、地方气候和植被等因素的影响;长时间尺度,泥炭地有机碳的转化,受气候条件控制;(5)总结泥炭分子化石特征、泥炭有机质各组分含量及植物残体组成随深度的变异规律,分析结果显示该泥炭地层形成过程中,1500a B.P(210cm)可作为划分前后晚全新世的界线,前期的基调是气候偏暖,但又有几次偏干冷气候的反复,后期气候以干冷为主,其间虽有几次上升波动,但整体趋势不变。

And 0.4~0.6 respectively for the induction coil with round crosssection and rectangular cross-section; The magnetic flux density of coil made with round pipe was nonuniform, especially near the inner wall of coil turns that caused a fluctuation of electromagnetic pressure on the surface of liquid metal and had a bad effect for forming a sample with uniform cross-section and smooth surface; The system of screen and restraint magnetic field not only had an efficient effect on restraining the electromagnetic stirring and stablizing meniscus, also caused the conecial periphery of melt to be vertical; The position of top and S/L interface of melt had a direct effect on the meniscus shape. The meniscus profile varied from cone-shaped through column to cucurbituceous shape with the increase of top height or decrease of S/L interface.
对圆形截面、矩形截面感应圈来说D/H分别取0.7~1.1,0.4~0.6较为理想;对多匝感应圈来说,在匝间处存在漏磁,易引起熔体表面起伏不平,这种现象在用圆铜管绕制的感应圈中较为明显;屏蔽—抑流系统的加入可以消除电磁搅拌,使熔体稳定性增强,同时可使形态呈锥形的熔体侧面变得垂直成为理想形态;熔体上液面、固/液界面的选位直接影响成型形态,上液面升高,熔体形态经历锥形→柱形→葫芦形的转化,固/液界面下降则经历锥形→葫芦形的转变。

Hydrostatic transmission is widely used in construction machine. The research of one of its hard cores, low speed high torque radial piston motor, is very important. To directly estimate the life of this kind of motor, and to design a orbit curve with the longest life at same condition, this paper gives theoretic research of the equal contact stress inner curve of radial piston motor. The research is divided into four parts:1 Taken all forces the piston endured into consideration when radial piston motor working, the force between roller and orbit is deduced.
静压传动技术在各类工程机械中得到广泛的应用,对作为其核心部件的径向柱塞式低速大扭矩液压马达的研究显得十分重要,为了能直接对这种马达进行寿命估计,并能在相同工况下求得寿命最长的轨道曲线,本文从设计等接触应力内曲线的角度对这类马达作探讨性的研究,主要从以下四个方面进行:(1)综合考虑径向柱塞式液压马达工作时的各种主要受力状况,对柱塞组件进行受力分析,并通过仿真分析影响轨道和滚动体间正压力的各个因素,得到正压力的简化表达式。
