开始发育

Paraffin slides observation found that the microspore of the RNMS line failed to vacuolate after its morphogenesis, disassembled and disappeared at last. After microspore morphogenesis, the breaking down of tapetum cells was delayed until microspore breading down.

石蜡切片细胞学观察，发现该隐性核不育能形成正常的四分体孢子，四分体释放出小孢子后，在单核花粉进入液泡化时小孢子的发育异常，不进行正常的液泡化，逐渐开始解体和消失；相应的绒毡层在小孢子形成后的降解延迟，绒毡层细胞的体积略有增大，在小孢子降解快结束时也很快解体。

Both the proteins components contained in haemolymph, fat body and ovary and the kenetics of the vitellogenin in haemolymph and ovary were analyzed by SDS—polyacrylamid electrophoresis, Ouchterlony plate tests and Rocket—immuno—electrophoresis. The results showed that the vitellogenesis initiated in adult stage and the Vg in haemolymph was detected firstly at 48h after eclosion. The titer of Vg in haemolymph raised rapidly in following 3 days and almost at the same time the vitellin appeared in oocytes. It was taken about 4—7 days after eclosion for the first eggs to grow up to the matured statics and to be laid out.

SDS-PAGE，双向免疫扩散和RIE分析粘虫生殖周期中血淋巴，脂肪体和卵巢中蛋白质谱带以及Vg滴度的变化，结果表明，Vg发生始于成虫期，Vg在血淋巴中的首现时间在羽化的24小时以后，以后连续三天血淋巴中的Vg滴度迅速上升，与此同时，开始沉积卵黄，卵母细胞逐渐发育长大，到成熟排出体外时大约历时4-7天。

The fertilization was processed by sperm in mature male gametophyte combining with egg cell on the top of archegonia on June 15 or so.

摘要樟子松发育成熟的雄配子体中的精子6月15日左右在颈卵器中上部与卵细胞结合，进行受精作用，其后，受精卵进行游离核分裂，形成8个子核时，开始形成细胞壁。

What has happened in this process is that on the one hand community organizations have emerged and communities burgeoned, and on the other the state has begun to sink its power center into communities, whereby the administrative build-up has taken shape.

伴随着这一过程的变化是，一方面，社区组织的出现和社区制社会的发育；另一方面，国家政权力量开始将其重心下沉入社区，出现了行政建设的过程。

The size of follicle begin primordial follicle to tertiary follicle(1.5～3mm).The number of mitochondrion increased,and the cristae increased.Gogi body change to type,cortical granule increased,and moved behind cytolemma.The proportion of small,middle and large follicles on ovary were 92.51%(92.51±5.87),4.60%(4.60±4.91) and 2.88%(2.88±2.22) respectively.

卵泡在发育过程中，卵泡细胞形成的突起与卵母细胞始终保持密切的联系：卵母细胞从原始卵泡到直径1.5～3mm的三级卵泡，细胞质中线粒体数量由少到多，线粒体内的嵴不断增加，高尔基体由不典型到变成典型，皮质颗粒由开始形成到形成较多的皮质颗粒，并逐渐地迁移到卵母细胞膜下。

Expression of tert and hprt genes were detected simultaneous in all single-copy embryos developed at 4-C (65h-post hCG, 4/4), 8-C (75 h-post hCG, 4/4), morulae (93h-post hCG, 4/4) and blastocyst (118h-post hCG, 4/4) stages and the level of transcription increased.

结果表明，持家基因hprt在成熟卵母细胞受精前后，以及胚胎早期发育过程中均存在转录本。40%卵母细胞中存在的tert mRNA在受精后很快降解，检测不到；胚胎基因组在2-C早期开始转录tert mRNA，转录水平逐渐上升。

I was married in 2001, there was no hepatitis B may be due to carelessness in the collective canteens transmitted on, the doctor was not a serious drug will be able to eat good, so I started medication, may be due to contraceptive failure, I soon became pregnant, I immediately stopped the medication, can I have been extremely worried, and five months pregnant when to do a color Doppler ultrasound, the doctor said that normal fetal development can not occur will affect the intellectual or other fetal abnormalities do?

我是2001年结婚的，当时没有乙肝，可由于在集体食堂不小心传染上了，医生当时说不严重吃些药就能好，于是我开始用药，可不久由于避孕失败我怀孕了，我立即停止了用药，可我一直担心极了，孕5个月时做了一次彩超，医生说胎儿发育正常，可会不会出现胎儿智力影响或者其他异常呢？

The Piwi clade is found in all animals examined so far, and its presence is tightly correlated with the emergence of specialized germ cells. Most animals separate germline and somatic cells early in development and restrict Piwi expression specifically to germ cells.

Piwi蛋白迄今为止被发现存在于所有动物中，它的存在与专门的生殖细胞紧密相关，大多数动物在发育的早期开始了不同组织和体细胞的分离和分化，并且对于生殖细胞的Piwi蛋白的表达进行特别的限制。

Secondly, the incisors grow faster, then the beginning of next to no longer permanent, in the "free" environment will, of course, a large growth, but within the next two years to grow permanent incisors on the natural limits; the most important point is that "parents feel that the incisors are the wrong impression", after the permanent teeth will not grow up stereotypes, so on the child's little face, mouth does not match, it appears to "Super", as the children grow up day by day face, bone development, facial development, such as children and adults will face the size of incisors is coordination of the match,"So we say that time will the children from 'ugly duckling' change 'Swan'."

其次，门牙长得快，这时旁边的恒牙都没开始长，在&无拘无束&的环境下当然会生长得大一点，但两年内旁边恒牙长出就自然限制了门牙；最重要的一点是，&觉得门牙大都是家长的错觉&，恒牙定型后不会再长大，所以放在孩子的小脸、小嘴中不匹配，才显得&超级大&，随着孩子脸形一天天长大，骨头发育、面部发展，等孩子成年时门牙就会和脸形大小十分协调、般配了，&所以我们说时间会让孩子由'丑小鸭'变'天鹅'&。

Ordovician karsts are well developed in the Yingmaili and Halahatang areas of North Tarim Basin.

塔里木盆地北部哈拉哈塘和英买力地区的奥陶系古岩溶非常发育，随着勘探程度的提高和地质认识的深入开始引起重视。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
