Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

It can prevent and cure the infectious diseases with significant harm, such as long-term infecundity induced by reproductive infection of animals, swine high fever (e.g."Porcine Reproductive and Respiratory Syndrome Virus" and eperythrozoonosis), newcastledisease, avian influenza and bursa of fabricius, etc.

对于动物生殖系统感染所引起的长期不孕、猪的高热性疾病(例"猪蓝耳病"，"附红细胞体病")、鸡的新城疫、禽流感、法氏囊等一系列具有重大危害的传染性疾病，具有良好的预防和治疗作用。

Under light microscope, the egg is an oblated and agglutinated demersal with a narrow perivitelline space; eggs ranged in diameter from 1.95 to 2.38 mm with a mean of 2.18 ± 0.03 mm; their membrane are smooth and they have 5 to 7 cannular keratose egg-filaments; the oil globules are multiple, ranged in diameter from 0.05 to 0.50 mm and in number from 7 to 145 with a mean of 28±2, the position of them migrate during embryonic development; the yolks are ivory-white with no segments, ranged in diameter from 1.00 to 2.30 mm with a mean of 1.90 ± 0.03 mm; the development phases of the embryo are variable. So they were identified as the eggs of one Beloniformes.

在光学显微镜下：卵呈微扁圆形，卵径1.95~2.38mm，粘着沉性；卵黄间隙较窄，卵黄囊呈乳白色，无龟裂；卵膜平滑，在其表面有5~7根细长角质管状卵膜丝；多油球数不定（4~145），油球径0.05~0.50mm，油球在卵黄囊中的位置随不同的发育时期而不断发生变化；胚体处在不同的发育阶段，其特征符合颌针鱼目鱼卵的特征。

Although the megagametophyte formed and even the double fertilization had been finished 70 days after pollination at normal temperature, the megasporogenesis had not yet been finished at low temperature.

低温(12-18℃)处理的蝴蝶兰，授粉50d开始分化胚珠原基、60 d胚囊处于大孢子母细胞时期，比常温(20-25℃)下的推迟10-15 d；授粉70 d，常温下的蝴蝶兰植株已完成雌配子体发育和双受精，而低温处理的蝴蝶兰仍未完成大孢子的发生过程。

During the development three outstandingcharacteristics were observed:three kinds of different division taking place;.the orientation of spindle to be fixed in the three mitosis of one-nucleate embryo sac;.changes of starch grains during megagametophyte development to be regularity.

单核胚囊三次有丝分裂纺锤体的定向较为固定。

The results are summarized as follows: tin the polygonum embryo sac of tetraploid grape , megaspore telrad arranged in straight line.

结果如下：在四倍体葡萄的蓼型胚囊中，四分体孢子呈直线排列，合点端的大孢子发育胚囊。

Mature embryo sac can form from megaspore mother cell on the modified VW medium supplemented with 0.5mg/L BA and 0.1 mg/L NAA.

在培养基无外源激素或仅含生长素或细胞分裂素时，雌配子体的发生过程不能顺利完成；在改良VW培养基上添加0.5 mg/L BA和0.1 mg/LNAA时，形成成熟胚囊。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
