A suspensor-like structure was formed on the bottom of the proembryo. Along with the constant growth of the proembryo, its shape converted from long-ellipse to obovate, at last it evolved as a globular embryo with smooth surface, and there were absciss layer in the joint of the bottom of suspensor and matrix tissue.

The experimental results show that:(1) for ideal spheres, the attenuation coefficient of velocity is constant, the air drag coefficient is slightly affected by the initial velocity and is a linear function of initial velocity, and (2) for real fragments formed by a warhead, the flight performances are different from ideal spheres, the air drag coefficient is affected by the flight velocity and is a linear function of flight velocity.

实验结果表明：(1)对于理想球形钨合金破片，在同一初始速度条件下，衰减系数为常数，空气阻力系数与初始速度有关，两者成线性关系；(2)对于经历爆轰驱动的球形钨合金破片，由于有轻微的质量损失和变形，速度衰减规律与理想球形钨合金破片有明显的区别，空气阻力系数与飞行速度有关，两者成线性关系。

In this study, preparation of chitosan molecular imprinted resins were studied, and a simple method with a nozzle was developed, in which molecularly imprinted chitosan resin was made for hemoglobin as"print"molecule and chlorohydrin was used as crosslinker.

采用滴加成球法制备出球形壳聚糖介质，研究了三聚磷酸钠溶液浓度及空气流速对成球的影响，得到其最佳条件为：三聚磷酸钠溶液浓度3％；空气流量为1.8m〓／min，线速度为23.81m／h。

The content of the irregular bigger drop phase approached to pyrope. It showed that the crystallization and phase separation mechanics of the glass was the nucleation-and-growth transformation and the crystallization is bulk crystallization. The activation energies of phase separation and crystallization were calculated by the modified Kissinger method, about 310.445 KJ/mol and 249.26 KJ/mol respectively. Using the aluminum hydroxide as the reference, we calibrated the phase separation exothermal enthalpy of the quenched and nucleation treated glass, ca

The results show that, by the way of optimizing preparation condition, the spherical zirconia powders with suitable particle size distribution are prepared using chemical precipitation method. Using heterogeneous chemical precipitation coating technique, the sph, erical nickel coated zirconia powders are prepared and the heterogeneous nucleation can be done on the surface of spherical zirconia powders. The thickness of coated layer, homogeneous degree and crack of surface can be controlled by the way of controlling powder concentration, adding rate of reactants feeding and adding surface active agent.

研究表明，采用化学沉淀法，通过优化制备工艺条件，可以制备粒径分布较均匀的球形氧化锆粉体；利用非均相化学沉淀包裹技术制备的金属镍包裹氧化锆微球粉体，球形氧化锆颗粒表面作为异相成核的场所，通过控制颗粒浓度、加料速度以及添加表面活性剂等工艺条件，可以调控包裹层厚度、表面均匀度以及表面裂纹等。

Low density silicon nitride with about 55% porosity and globed macropores was prepared by reaction-bonded raw silicon powder and adding 30% in mass pore-forming agent of benzoic acid ball-like particles.

以硅粉为原料，添加质量分数为30%的成孔剂球形颗粒，反应烧结制备了气孔率为55%，具有球形宏观孔的低密度多孔氮化硅陶瓷。

Fruit narrowly ellipsoid, ovoid, or obovoid; pericarp thin and opening on 1 side or thick and splitting at angles.

果狭椭圆形，卵球形，或倒卵球形；果皮薄和在1 边裂开或厚且成角度开裂。

When cultured on the medium with different auxin , root segments could elongate and branch, and the addition of 1mg/l IBA into the medium was the most suitable for long-term root culture. Calli could be induced from root explants in the presence of 2, 4-D and when transferred onto E medium, they transformed further into embryonic calli which could develop into normal plants through the stages of globular-embryo, heart-shaped embryo, torpedo-shaped embryo, cotyledonary embryo.

培养基中添加生长激素（IAA，IBA，NAA）能够诱导无菌苗根切段的生长和分枝形成；而1mg／l IBA的存在，最适合于根的长期离体培养。2，4-D的存在能够诱导根外植体脱分化形成愈伤组织，愈伤组织转移至E型分化培养基能够转变成胚性愈伤组织，并进一步经球形胚、心形胚、鱼雷形胚、子叶形胚发育成正常植株。
