In order to investigate the effect of IFN-γon the expression of TNF-αin the hypothala- mus-pituitary-ovary axisof RU486-induced aborted SD rats, RU486 was used to establish the abortion model, then the aborted rats were administrated with different doses of IFN-γintraperitoneal injection, the method of immunohistochemical ultrasensitive SP was us- ed to study the variation of positive TNF-αcells in hypothalamus, pituitary, ovary and uterus in normal pregnant group A, aborted model group B and three different doses of IFN-γgroup C,D,E. The main goal of this research was to study whether the low dose of IFN-γcould have a protective function to pregnancy and the mechanism of its function so as to provide morph- ologic basis for the scientific using of IFN-γin the process of animal abortion control.

为探讨IFN-γ对流产大鼠下丘脑-垂体-卵巢轴(hypothalamus-pituitary- ovary-axis，HPOA )TNF-α表达的影响，本试验用米非司酮(RU486)建立SD大鼠流产模型，通过腹腔注射不同剂量IFN-γ，采用超敏感免疫组织化学SP法(链霉素抗生物素—过氧化物酶法)，观察了孕13天(d13)SD大鼠正常妊娠A组、流产模型B组、不同剂量IFN-γC、D、E组下丘脑、垂体、卵巢、子宫TNF-α的表达变化，探讨低剂量IFN-γ对妊娠是否有保护作用及其作用机制，期望能为在妊娠过程中如何科学应用IFN-γ防止动物流产提供形态学依据。

During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined. Seedlings grew fastest under 0.6% NS, suggesting that nutrients stored in seeds played an important role at the early growth stage. The treatment of 37.3% NS was best for established seedlings in seedling height, basal stem diameter, paripinnate number, rachis length, the maximum sub-leaflet number of individual paripinnate, leaf area per seedling, relative growth rate and net assimilation rate. Light intensity was positively correlated to total dry weight, and negatively to specific leaf area. The maximum of SLA was observed under 15.5% NS.

And destruction usually occurs on angle.(2)Around the keyhole, the stress centralizes, column" edge opt to inflects in local.(3)The change of friction coefficients or bolt pretension forces can"t affect the performance of top-and-seat angel connections so much.(4)The parameters of angel influence joints performance greatly.

破坏一般是由于顶角钢上应力过大，形成塑性铰而导致的；(2)柱翼缘在与顶角钢相连的螺栓孔周围，存在应力集中，容易导致局部屈曲；(3)材料抗滑移系数的改变和螺栓预拉力的大小对于节点受力性能的影响并不明显；(4)角钢参数的改变对节点的各项性能影响显著，增加角钢厚度，节点的强度、刚度和延性都能得到明显的提高；增加角钢长度，节点的强度和刚度也有较大的提高，延性则略有下降；(5)柱轴压比过大时，节点的承载力、刚度以及变形能力明显下降；(6)螺栓中心线到角钢肢背距离增大时，节点的强度和刚度有所下降，但延性略有增加。

The horizontal bending moment and bending stress of the crossbeams rise quickly with increasing of the constraint stiffness of the lower chord joint to the crossbeam, the axial stress of the low chords and the continuous length of the floor system and with decreasing of the distance between the stringer and the low chord.

Using harmonic analysis of the calculated tidal level and current, the distributions of co-tidal lines for K1, O1, M2 and S2 are obtained, whose maximum amplitudes can reach 112 cm, 96 cm, 50 cm and 15 cm, respectively. The distribution of the maximum probable current velocities in Qinzhou Bay is basically the same as that of isobaths, and the maximum probable current velocity can reach 200cms^(-1) nearby the Longmen Harbor. It is concluded by the analysis of K1 and M2 tidal current ellipses that the flow is rotating at the mouth of the bay, while its retilinear flow is in the nearshore area, estuaries and channels. The distributions of the major axes are closely related to the topography, and the rotation directions of both constituents are clockwise.
