Based on above studies, some main conclusions were obtained as follows : 1 the diatoms forming mats in low latitude west pacific is"shade flora"diatom Ethmodiscus rex Hendey; 2 the sites found diatom mats are zone distributed, the direction is NW-SE and most distribute in the deep water area with flat seafloor, between 17°N~20°N and the water depth 4837-6150 m below Carbonate Compensation Depth (CCD 3) AMS 14C dates show that the sediments rich in diatom mats occurred during 16.0 ~ 28.6 ka B.P., which means the bloom mainly occurred in last glacial maximum, while there are not diatom mats deposits in other layers; 4 A total of 101 diatom taxa belonging to 40 genera had been identified from the 155 samples in the two cores WPD 03 and WPD 12, and the relative percentage of Thalassionema frauenfeldii are the highest, Thalassionema nitzschioides、Azpeitia nodulifera、Hemidiscus cuneiformis、Nitzschia marina take the second place.

Total submergence largely decreased biomass production and growth in length,with less effect on shoot numbers.Increased elongation of the growing internodes of up to 140% is caused by submergence.Nutrient such as N,P,K do significantly affect on growth.No mater lack of any element will decrease the biomass,the result same as the oligotrophic conditions.But lack of phosphorus is the worst mater.
而淹没式淹水可能使生物量降低,但是植株的高度有所增加,因为淹水可以使芦苇的节间高度提高140%;对根茎的数量没有很明显的影响。N、P、K等营养元素对芦苇生长也具有重要的作用,无论缺少哪一种对芦苇生长都不利,跟完全贫营养状态没有明显的区别,但是缺P时芦苇生长是最差的。

This method can make sure the structure radiant sound status in total noise and the detail phonate part quickly and correctly.(3) Study on the control mechanism of structure noise radiated from rotary machines, we build a common model of rotary machine structure noise analysis relied on the general characters of rotary machines. Based on this model, we analyzed various influence factors to structure radiant noise using the union of revolution and numerical calculation method. We found that the joint stiffness between the rotor and the frame is the most sensitive parameter of structure radiant noise by calculating and analyzing.
根据本文对于旋转机械结构噪声控制技术的研究结果和惯性振动筛工作的特殊要求,对有关参数的选择进行了讨论,并通过试验为降低惯性振动筛噪声找到了两个新的方法:即,在轴间相对运动要求不高的情况下,可以在激振器与筛体之间安装一组减振器,通过适当选取减振器参数,既可以使机体在工作频率附近获得稳定振幅,保证振动筛正常工作,又可以使机体的高频响应减小,降噪效果显著;反之,如果轴间相对运动精度要求(来源:1aABC论文网www.abclunwen.com)较高,可以采用空心滚动体轴承,在保证滚动体强度的条件下也可以获得较好的降噪效果。

Meanwhile, the surface layer gets fine crystal grain with dispersive and homogeneous distribution of WC grains and Co binder from rapid melting and resolidification during HIPIB irradiation. Minimizing the mean free path in Co binder by decreasing the WC grain size leads to an increase in resistance to plastic deformation in the binder.
HIPIB强烈非平衡作用下的重熔和再结晶使WC晶粒细化且分布更均匀,同时,表层析出弥散分布的Co_3w_9C_4相,使Co粘结相产生强化,导致Co粘结相的平均自由程降低,从而增强了Co粘结相抵抗塑性变形的能力,提高了辐照硬质合金的耐磨性能。

Beta-thalassemia major is a serious hereditary hemolytic anemia which does great harm to human being.It is a monogenic disease characterised by a reduced synthesis of beta-globin chains,which dues to the Doint mutation or deletion of beta-globin gene and its control region.It not only decreases the hemoglobin level,but breaks the balance of alpha/beta synthesis ratio.The major cellular pathogenetic mechanisms in beta thalassemia are based primarily on the deleterious effects produced by the accumulation of the excess alpha globin chain.These excess alpha-globin chains cannot form stable tetrameric structure and deposit in erythroid cells.They cause large ineffective erythropoiesis on their own,accelerate red cells destruction,and lead to hemolysis.
地中海贫血是一种对人类健康危害严重的遗传性溶血性贫血病,是因β-珠蛋白基因及其调控序列的点突变或缺失致使β-珠蛋白肽链合成减少或完全停止,这不仅使患者血红蛋白水平降低,而且使原来在数量上与之持平的α-珠蛋白肽链相对过剩,这些相对过剩的游离α-珠蛋白肽链并不能形成稳定的四聚体,它们沉积在红细胞中导致了大量无效红细胞生成和红细胞寿命缩短,引起了严重的溶血性贫血。
