Using histological staining methods, SABC immunocytochemical technique and electron microscope technique, the difference of the encephalon, the pituitary and the gonad in precocious and unprecocious large yellow croakers are compared.

本文应用组织学、免疫细胞化学及电子显微镜技术对一龄性早熟和未早熟大黄鱼的脑和脑垂体以及性腺进行了比较研究，结果表明： 1。

The experimental results showed that the com- bining ability was different among characters of different parents.Early maturity of cucumber was controlled by nonadditive effect.

试验表明：不同亲本间各性状的配合力有差异；早熟性以非加性遗传为主，狭义遗传力较低，总产量、雌花节率以加性遗传为主；群体雌花开放期主要取决于基因型。

A Beijing doctor, who runs the city's first sexual precocity clinic, said her research into the condition showed that in Shanghai, the rate was as high as 1 percent.

经营着北京第一家性早熟诊所的北京医生说到，根据她的调查，在上海这一比例高达1%。

At last, he came up with the cause of the prematurity of the scientific discovery, and held that creative science was as unique as that of art.

最后，他给出了科学发现的早熟性出现的原因，并认为，科学创造与艺术创造一样具有其独特性。

GnRH-ir fibers distribute in the various brain region from the olfactory bulb to the cerebellum. They are especially abundant in the hypothalamus, the preoptic area and the ventral telecephalon. The immunopositive reaction in precocious fish is evidently stronger than that in unprecocious fish, and there is only very weak reaction in the gonadal undeveloped fish. The differences are most obvious in the hypothalamus, but not in other areas.

性早熟大黄鱼的神经内分泌细胞对GnRH抗血清的免疫阳性反应明显，无论在细胞的数量和免疫强度都比未早熟鱼多和强，在性腺尚未发育的幼鱼脑中仅有弱的免疫阳性，这种差异在下丘脑外侧结节核及视前核处最为明显，在其它GnRH阳性部位则差异不显著。

Through a relaxed selection of 10 passages, the precocious line showed genetically stable in its prepatent time, OPG, and as well as its pathogenicity.

对选育的早熟系进行放松选择传代10次，其潜隐期、OPG、致病性均保持了早熟系的特征。

But theimprovement was still needed because of its late maturity and low grain-weight. The NChybrid is crossing with other vulgare so as to breed new NC hybrid suitable forproduction.

但在千粒重和早熟性上还有欠缺，目前正用其它普通小麦品种进行转育，以期培育出生产上能用的核质杂种小麦。

At the same time, fiber strength and micronaire would be improved with paying attention to the selection of high lint index. For Yuncheng, the key was to make the period from sowing to flowering long properly for improving the fiber length of short season cotton.

早熟性平均狭义遗传率，安阳点为46.0％，运城点为10.9％，石河子点为12.3％，棉株各性状的综合遗传率总体趋势是：安阳最高，其次为运城，石河子最低。

The introduction adaptation of Kentucky bluegrass varieties in Beijing is summarized. Indices including growing habit, turf quality, turf duration, winter and summer survival, disease resistance were analyzed.

该文根据3a多的试验，分析了草地早熟禾的生长特征和特性，以及形成草坪的质量、持续年限、越冬越夏性和抗病性等结果表明，草地早熟禾各品种差异十分明显，大多数品种比较适宜北京种植。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
