Both the new peniculus 1 and the old haplokinety separated at the telophase.The two germinal rows germinal rowsfor both the daughter cells appeared almost at the same time;(2) The macronucleus became shorter and thicker, finally oblate during the division of the cell. Then the macronucleus restored its original shape, band-like form. The micronucleus were divided into two before the macronucleus division;(3) The original scopula and stalk contributed to the old cell. The new cell formed scopula gradually after the cell division.

同时，新仔虫的第一咽膜(P′1)也开始由老单毛基索复制，并在细胞分裂后期与老结构分离；(2)大核在虫体分裂过程中由长带状逐渐缩短变粗至扁圆形，于虫体即将分开时迅速拉长，然后分裂为二个新大核；小核分裂先于大核，在两仔虫口纤毛器即将分开时完成；(3)原帚胚及柄归属老仔虫，新仔虫的帚胚在虫体分裂后逐渐形成，柄内肌丝则在柄鞘形成后逐渐长出。

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。

The quadrivalent was made of the normal 11 chromosome, the normal 18 chromosome, the translocated 11; 18 chromosome and the translocated 18; 11 chromosome.

精母细胞中SC分析，在早粗线期、中粗线期和晚粗线期精母细胞中，均发现22个常染色体SC和一个XY-二价体，即23个二价体；未发现22个二价体和一个单价体细胞，说明这条rob（21q；21q）染色体的两个臂完全配对形成发夹结构，形态上与正常SC一样，但与正常21号SC相比，其相对长度变短，由正常的1.5±0.1变为1.25±0.05。

Plastic strain stretching to failure at room temperature induced over 85% volume percent of martensite at all of tested steels. The higher cold rolled strain of steels, the smaller strain at which martensite transformation onset during stretching, but it didn't increase the saturate volume fraction of martensite.

所有301L冷轧板拉伸试样近断口处都发生了85 %以上的马氏体相变，轧制变形量增加，室温拉伸应变诱发马氏体转变开始的应变减小，但未增加马氏体转变饱和值。

6Mm, width is about 0.15mm; When the sludge begin to acclimate to the nitrous nitrifying conditions, bacillar flocculation gradually dwindle and decomposition, still disperse into little flocculation.

6高浓度氨氮废水亚硝化稳定期的特征污泥相为：杆状絮体，长度约0.25～1.6mm，宽约0.15mm；当污泥开始对亚硝化产生适应后杆状絮体逐渐变小、解体，直至分散成为很细碎的絮体。

The pressor effect of adenosine was due to carotid body cheoreceptor activation. However, a slight increase of ABP induced by intracarotid bolus injection of adenosine following the section of carotid sinus nerves was observed in a few rats, which implied that the central effect might be involved in the pressor effect of adenosine. The delayed effect of adenosine may be attributed to the direct actions (including the negative chronotropic action, thenegative dromotropic action, the negative inotropic action and the vasodilator effect) of adenosine on the heart and blood vessels.

前一效应主要与颈动脉体化学感受器的激活有关，但在少数动物，颈动脉内注射腺苷的升压效应在切除窦神经后并未完全消除，表明腺苷有可能进入神经中枢而发挥作用；后一效应可能由腺苷直接作用于心脏和血管，通过其负性变力、变时、变传导和血管扩张等作用，导致心脏自律性降低，输出量减少和外周阻力下降。

The influence of sulphonated naphthalene formaldehyde condensates,polycarboxylic series(SR3),aminosulfonic acid-based series on rheology of sulphoaluminate cement paste is investigated.

利用缓凝剂有效控制了硫铝酸盐水泥的凝结时间；利用浆体稳定剂成功解决了水泥净浆的板结、泌水问题；从浆体流变学角度研究了外加剂—硫铝酸盐水泥浆体体系稳定性。
