During the fertilization of angiosperms, the degenerated synergid induces a pollen tube to enter and break the pollen tube to release two sperm cells, which fuse with the egg and central cell.

在受精过程中，助细胞吸引花粉管向雌配子体生长，并接受花粉管长入细胞程序死亡助细胞中。接下来的花粉管停止生长和花粉管顶端破裂释放出2个精细胞的过程可能也依赖于助细胞。

Sperry showed that the regenerated retinal axons always innervated the original sites of termination in the optic tectum. This experiment strongly disprove the resonance hypotheses proposed by Paul Weiss, who suggested that the nerve growth and synapse formation are largely random events, and the precision of connections between nerve cells emerged by selectively eliminating the inappropriate connections, only at later developmental stage.

Sperry的实验在支持Cajal假说的基础上，进一步明确发育过程中轴突的生长及突触的形成具有内在决定性，并且有力地反驳了当时占主流地位的由Paul Weiss于1930～40年代提出的resonance hypothesis，后者认为轴突的生长和突触的形成大多是一些随机事件，成年脑中的精确联系是通过对随机形成的不恰当联系进行选择地消除形成的。

The model of aging and ovariectomized female rat were established to study the expression and distribution of ER, NGF and ChAT in the cerebellum, diencephalons, telencephalon and pituitary after 17β-estradiol treatment, and the mechanism of its effects were discussed.

另外，还通过在原代培养的神经细胞生长过程中添加17β－雌二醇来研究雌激素对体外培养神经元的生长及神经分泌功能的影响。主要实验结果如下： 1。

Mutants related to shoot branching are isolated in pea? Arabidopsis? petunia? rice? tomato and maize, such as revoluta? pinhead? monoculm1(moc1)? lateral suppressor? blind/torosa related to axillary meristem initiation; more axillary growth? ramosus? decreased apical dominance associated with axillary meristem outgrowth; supershoot/bushy? Teosinte branched1 (Tb1) contacted with axillary meristem initiation and outgrowth.

在豌豆、拟南芥、矮牵牛、水稻、番茄和玉米中获得到很多与分枝发育相关的突变体，如与腋生分生组织的形成有关的revoluta、pinhead、monoculm1(moc1)、lateral suppressor、blind/torosa等突变体；与腋生分生组织的生长有关的more axillary growth、ramosus、decreased apical dominance等突变体；与腋生分生组织的形成和生长都有关的、supershoot/bushy、teosinte branched1(tb1)等突变体。

It was also observed malpighian tube and tail spine teratogenesis in embryo development test, more than 50% of daphnids being deformed during the test.

胚胎生长试验结果显示，氯化三丁基锡对大水蚤胚胎具有高毒性且导致胚胎生长畸形之比率高达50%。

Long wavelength such as red light did not favour the accumulation of flavoniod and terpene,but promoted the growth of Ginkgo biloba.

结果表明：长波段的光不利于黄酮和内酯类物质的积累而有利于植株的生长；短波段的光不利于生长但有利于黄酮和内酯类物质的积累。

Porphyridium cruentum were treated with some antibiotics which were used as genetic selected marks in genetic engineering. The results showed that the algae cells could resist high concentration of Penicillin,Streptomycin,Gentamicin and Kanamycin, without any influence at the dose below 100 u/mL of which can kill bacterium adhere to the algae cells . These antibiotics can be used to repress bacterium in purifying algae strain.Porphyridium cruentum is high sensitive to Erythromycin,Terramycin and Ofloxacin....

研究了基因工程中常用抗生素标记对紫球藻的生物学效应，结果表明紫球藻对青霉素、链霉素、庆大霉素以及卡那霉素较不敏感，剂量在100u/mL以下对其生长无显著影响，但能抑制或杀灭伴生的杂菌，因此这些抗生素可用于藻种纯化过程中抑菌；紫球藻对红霉素、氧氟沙星和土霉素非常敏感，低质量浓度就能杀死藻细胞，可用作基因工程或遗传育种的抗药性选择标记；对四环素和氯霉素较为敏感，明显抑制细胞生长，并呈浓度梯度效应。

The results revealed that the ZnO tetrapod nanostructures have two different kinds of growth mechanism, one is refined as the rod-based growth model; the other is regard as the growth speed competition of the crystal plane.

研究表明，ZnO四足纳米结构的生长过程中遵循两种不同的模式，一种为以纳米棒为基础的成核模式，另一种为成核区域各晶面竞争生长的成核模式。

At the rear was an innovative combination transaxle with the gearbox, clutch, differential, and inboard-mounted drum brakes.

在后面是与变速箱，离合器，差的创新结合变速，和内侧安装鼓式制动器。

For more people can apprecaite and have the master work, there is reproduction painting appears in the market, the large various selection of paint,the high saturation of color plus the plentiful sfumato, to make the reproduction perfect copy and detail as original painting, so as to meet the requirment of amateurs who love art paintings,they do not need to pay high price to get classical paintings.
