The common method, that all strong-correlation terms of the model are eliminated, can bring the loss in the engineering application, so the new method is proposed that the identified model reserves some correlation. The augmented matrix A is constructed by the outputΔW and the matrix S. The"determinating order based on ratio of determinant"is brought out to screen the strong-correlation terms in the structure identification. The latent root estimation is improved in screening the eigenvalues and eigenvectors. Thus the estimation precision is improved greatly.The consistence check of guidance instrument error coefficients of flight test and ground test is the purpose of flight experiment. The causes of inconsistency of the two models are analyzed. The hypothesis test of linear regression model based on F statistics is proposed to check the consistence.Finally, the instability of error coefficients is probably caused by the change of the flight environments, therefore, the relation between the error coefficients and flight environment is analyzed. The approach is presented to identify SINS guidance instrument error models and compensate the error in the segmented sections corresponding to the change of vertical acceleration of aircraft.

在结构辨识中,常用的方法由于将模型中的强相关项全部剔除而给工程应用带来损失,因此,本文提出了新的有益思想,即在保留一定相关性的基础上进行辨识:将输出向量ΔW与环境函数矩阵S构成增广矩阵A,然后采用"比定阶行列式"来剔除相关向量的方法,这样既可以尽可能多地保留了对落点影响大的强相关参数,又可以对落点影响小的强相关参数给予剔除;在参数估计中,改进了特征根估计中特征根和特征向量的筛选方法,提出"近零"准则,从而大大提高了参数估计的精度;再者,鉴于天地模型"一致性"检验是飞行试验和SINS制导工具误差系数分离的主要目的,因此,本文又深入分析了造成天地模型不一致的原因,提出了采用基于F统计的线性回归模型假设检验方法来进行捷联制导工具误差模型的天地"一致性"检验;最后,鉴于飞行环境剧烈变化可能会对惯性仪表误差系数稳定性带来一定的影响,因此本文深入地分析了SINS制导工具误差系数与外界环境的关系,提出了基于过载变化大小的分段辨识和分段实时补偿的算法。

This paper has studied the physiological and biochemical changes during the period of forming strong buds of tree peony, and expect to provide academic basis for extending its view value and economic benefit . The main results are as the following:1 Under the field condition, Characteristics of photosynthesis of tree peony are very regular. From before blooming to the prophase of abducting buds that after blooming ,that is April,May and June,the net photosynthetic rate of tree peony is higher than the other period .It indicates that this period is very important for accumulating photosynthetic products of tree peony . So, if we want to get quality flower of tree peony ,it is very important to strengthen the management of tree peony cultivation and to ensure provide the fertilizer and water.2 From the middle ten days of June, with the time elapsing and with the environment conditions worsening, the characteristics of photosynthesis of tree peony decline deeply. But it is different among different tree peony breeds. For example , cv. Wu Long Peng Sheng can also has higher net photosynthetic rate, it indicates that cv. Wu Long Peng Sheng is super than the other two tree peony breeds when adapting the environment conditions and cv. Wu Long Peng Sheng has wide prospect to extend .3 The main factors of effecting the characteristics of photosynthesis are stomatal factor and non-stomatal factor ,that is the ability of photosynthesis of leaf cells. Under the environment of high light intensity in midsummer, if overshadow tree peony properly, then it can slow the declining of chlorophyll content, and increase the net photosynthetic rate and benefit for the accumulating of photosynthetic products.4 The content of soluble sugar in the root of tree peony is the highest among different organs during the period of forming strong buds . According to analyse ,we believe that the soluble sugar will compose starch then, and provide the solid base of material for the growth and development next year. It provide us strong academic basis of adopting the method of cultivating root and protecting root under thefield environment conditions .In other words ,it will help to increase the health level of the whole plant of tree peony and will be beneficial to forming quality tree peony flower if we strengthen the management of root. 5 To tree peony, the endogenesis hormone is important for its growth and development .In the prophase ,that is about the blooming of tree peony and the mid-summer ,IAA and ZR contents are higher and GA content is lower and its changes are very little, and the content of ABA is decreasing . This indicates that IAA and ZR act the important promote function for growth and development of tree peony in this period, and the function of GA is not important. Bur in the period of anniversary senescence of tree peony , the content of IAA and ZR begin to decrease ,while the ABA content has a certain rebound .T

本研究对几个牡丹品种壮芽形成过程中的某些生理生化变化做了研究,以期了解牡丹生长发育过程中生理生化的变化规律,探讨大田栽培条件下提高牡丹花质量的栽培措施和管理技术,为提高牡丹的观赏价值和经济效益提供理论依据,结果如下:1 大田栽培条件下,牡丹光合特性在生长发育过程中表现出极强的规律性,牡丹各品种的光合速率从牡丹开花前,到牡丹花谢后的花芽诱导期前期(6月10日之前),也就是在4、5、6月份,各牡丹品种的净光合速率相对与其他时间都维持在比较高的水平,这说明,在这段时间,是牡丹光合产物积累的重要时期,因此,要保证得到高质量的牡丹花,在这段时间加强对牡丹的栽培管理,保证这个时期的肥水供应十分重要。2 从6月中旬后,随时间的推移,环境条件的恶化,牡丹的光合性能剧烈下降,但是不同牡丹品种间仍有差异,比如,乌龙捧盛仍可维持较高的光合水平,这说明了乌龙捧盛这个牡丹品种对于环境的适应性较之其他牡丹品种高,有着广泛的推广前景。3 影响牡丹光合性能的主要因子是气孔因素和非气孔因素即叶肉细胞的光合能力,在盛夏高温高光强的环境条件下,对牡丹进行适当遮荫,能缓解牡丹叶绿素水平的下降,适当提高Pn,有利于光合产物的积累。4 可溶性糖在牡丹各品种的壮芽形成过程中,根中可溶性糖的含量在牡丹各部位中始终维持最高水平,分析认为这些可溶性糖在根系中进一步合成淀粉等储藏性物质,为来年牡丹的生长提供雄厚的物质基础,这为我们在大田栽培条件下对牡丹采取养根护根的栽培措施提供了有力的理论依据,即在大田栽培条件下,加强对牡丹根系的管理,有助于提高牡丹整株的健壮程度,有益于形成高质量的牡丹花。5内源激素对牡丹的生长发育调节作用是十分明显的,在前期,即开花前后和盛夏,IAA和ZR含量维持在比较高的水平,GA含量低且变化不明显,ABA含量逐渐降低,说明了IAA和ZR对牡丹在这段时间内的生长发育起到重要的促进作用,GA的作用不是很明显,ABA可能在高温高光强下有明显的升高,也说明了ABA的确有一些促进作用,但是到了牡丹周年衰老期,IAA和ZR的含量开始下降,ABA含量却有了一定程度的反弹,说明了IAA和ZR的作用开始降低,ABA起到了促进衰老的作用

In the first way, the other five medicines except Radix sophorae flavescentis against NDV was better. In the second way, the effect of Herba houttuyniae, Patrinia villosa juss, Rhizoma polygoni cuspidati and Radix isatidis to NDV was better, but Radix sophorae flavescentis and Folium isatidis had little effect. In the third way, Radix isatidis, Herba houttuyniae, Patrinia villosa juss were more effective than Folium isatidis, Rhizoma polygoni cuspidate. In short, the effects of Radix isatidis, Patrinia villosa juss and Herba houttuyniae on NDV were higher.The first of three more satisfactory complex composites obtained from the experiment was Folium isatidis, Herba houttuyniae, Rhizoma polygoni cuspidati, Patrinia villosa juss and Radix sophorae flavescentis.

在第一种加药方式中:只有苦参没有产生作用,其余五种药物抗NDV的作用均较强;在第二种加药方式中:鱼腥草、败酱草、虎杖、板蓝根效果较好,而苦参及大青叶则几乎不起作用;在第三种加药方式中:板蓝根、鱼腥草、败酱草有较强的作用,大青叶、虎杖次之,由以上结果可以看出在三种方式中,板蓝根、败酱草和鱼腥草抗NDV的作用较强。

Therelationship between the turbulent kinetic energy and its dissipation rate,whichis widely used to parameterize the dissipation rate in turbulence closure models,is found to hold well for both reversing and rotating flows,but with differentcoefficients.Microstructure profiling measurements at two comparative stations (a deepercentral basin and a local shelf break) in the stratified Yellow Sea are analyzed,with emphasis on tidal and internal-wave induced turbulence near the bottomand in the pyenocline.The water column has a distinct three-layer thermohaline structure,consisting of weakly stratified surface and bottom boundary layers anda narrow sharp pycnocline.Turbulence in the surface layer is controlled by thediurnal cycle of buoyancy flux and wind forcing at the sea surface.while thebottom stress induced by barotropic tidal eurrents dominates turbulence in thebottom boundary layer.The maximum level at which the tidally enhanced mixingcan affect generally depends on the magnitude of the tidal current,and it canbe up to 10-15 m in the Yellow Sea.This suggests that,in the deeper regionsof the shelf seas,turbulent dissipation and mixing are very weak at the levelsbetween the near-bottom tidally enhanced layer and the pycnocline.Therefore,these levels provide a significant bottle neck for the vertical exchanges.In theshallow regions,however,the tidally-induced turbulence can occupy the wholewater colum below the pycnocline.A quarter-diurnal periodicities of the turbulentdissipation rate and eddy diffusivity are found at different heights with evidenttime lag.In the relatively flat central basin,the pycnocline is essentially non-turbulent and internal-wave activity is very weak.Therefore,vertical fluxes acrossthe pycnocline decreased to molecular levels.In contrast,internal waves of variousperiods can be always found near the local shelf break.

对强层化季节黄海两对比性站位(分别位于中央海盆区与局地陆坡区)处层化、内波以及湍流混合特征的研究结果表明:1、强层化季节的陆架海水体一般呈现显著的三层热盐结构,在水体近乎混合均匀的上混合层与潮流底边界层之间为强跃层;2、近表层水体的湍流混合强度主要由海表浮力通量的日变化与海表风强迫控制,而在潮流底边界层内,潮混合是水体热量、物质、动量与能量垂直交换的主要机制;3、潮混合影响的深度由潮流大小决定,在黄海,一般可达10-15 m,因此,在水深较深的区域,在跃层与潮混合所至深度范围的上界之间存在湍流混合非常弱的区域,这显著抑制水体内物质的垂直通量,为物质垂直交换的瓶颈,而在水深较浅的区域,潮混合影响范围可至跃层底部,因此物质在跃层以下整个水体中混合非常均匀,当跃层内间歇性强混合发生时,可以产生显著的跨跃层物质输运;4、近底潮致强湍流耗散缓慢地向上传播,底上不同深度处垂直湍扩散系数也具有显著的位相差异,且二者均随时间呈现四分之一周日周期的变化;5、在地形较为平坦的中央海盆区,内波活动非常微弱,因此跃层内湍流混合非常弱,垂直扩散系数为分子扩散水平,跨跃层物质通量受到显著抑制,而在地形变化较为显著的局地陆坡区,内波活动非常活跃,除内潮的影响外,高频内波与内孤立波的影响也很显著,因此跃层内存在很强的间歇性强混合,内孤立波存在的区域,水体湍流混合显著增强。
