Combining ion exchange process and silicon hydrolyze process Silicon dioxide mother nuclide with a specific particle size was prepared from sodium silicate through the dropwise technique , then the large particle size , high concentration and stable silica sol was prepared . The stability of silica sol also can be improved by enwrap .

和"单质硅一步溶解法"相结合的方法，用离子交换法制备晶种，并采用滴加工艺制备一定粒径大小的二氧化硅作为母核，在催化剂和分散剂共同作用下水解单质硅的方法使二氧化硅母核颗粒进一步增长成大粒径的二氧化硅颗粒，并另外还采用水溶性高分子对纳米SiO_2粒子进行"原位表面包覆"提高其稳定性，制备了大粒径，高浓度，稳定的纳米硅溶胶。

The results show that the CD29, CD49, CD90 express in the gonium and the primary spermatogenous, but there are not expression in the oocyte, the second spermatogenous and the spermatocyte.

研究结果表明，CD29， CD49， CD90在雌性生殖腺各级卵母细胞中均不表达，位于生殖褶边缘的性原细胞中可见表达；在雄性生殖腺的初级精原细胞中表达，但在成团分布的次级精原细胞、各级精母细胞中均未表达。

The conversion boundary of self-incompatibility was researched by sowing by stage. Sunshine of day and temperature was studied critically by investigating leafage and researching traits indoors. The results showed that the daily minimum temperature was the principal factor of affinity conversion and the affinity conversion boundary was 16.5~18.1℃.HE97 was primarily regard as self-incompatible line in this research. The method was by inbreeding and sib HE97, Half the silk of HE97 and Zheng58. Inbreeding and cross have been done simultaneously. The extending condition of pollen tube was observed by dying the silk after pollinating 4 hours. The individuals with pollen tube were observed having seeds, while the individuals without pollen tube were observed having few seeds or no seeds. So this study regard HE97 as sporophytic self-incompatibility .The planting ration of female parent HE97 and male parent 87-1 was 4:1.The nature cross-pollination was studied by the theory of endosperm xenity, the study show that the setting percentage of HE97 was 625%, in which the seed in self was 70% and the seed in hybrid was 30%. This was consistent with the study of silk anatomy structure, then come to the same conclusion: compatible pollen germination and fertilization can stimulate the self-incompatible pollen germination and fertilization in the same corn cob.

通过分期播种，进行了光温敏自交不亲和材料HE97亲和性转换区间的研究，依据田间跟踪调查叶龄及室内考种研究了HE97亲和性转换区间的光温临界值，结果表明：1日最低温度是影响HE97自交不亲和性的主要原因，亲和性转换区间在16.5℃～18.1℃之间。2通过HE97自交和姊妹交以及将HE97与郑58作为双亲，各自的花丝一分为二，分别正反交，授粉后4个小时分别取其花丝进行固定、染色，观察花粉管的伸长情况，根据结实率与花粉管伸长的对应关系，结果发现观察到花粉管的对应植株收获到了种子，而没有观察到花粉管的对应植株结实率极低或没有结实，本研究把HE97初步划为孢子体自交不亲和类型。3以HE97为母本，87-1为父本，按4母：1父行比，通过花粉直感效应研究天然异交率，结果母本HE97结实良好(62%)，其中自交粒占70%，异交粒占30%，结合花丝切片观察表明，亲和花粉的萌发及受精会导致落在同一果穗柱头上不亲和花粉的萌发不再受抑制。

It also indicates that the expression of WT1 is regulated strictly in time and space, and the aberrant expression of WT1 may result in retarded differentiation of blastemal cell leading NR or nephroblastoma.

提示在散发性肾母细胞瘤发生中除WT1突变外，WT1表达延迟可能是其中起重要作用的机制之一；WT1基因与肾母细胞瘤的组织分化有关，可能诱导胚基细胞向上皮细胞方向分化。

Painters have developed to analyze the meaning of cross from its primary character, sacredness and contemporariness in the art of Christianity.

A pure and single K+ current of ultrarapid delayed rectifier K+ current or transient outware K+ current is respectively expressed on Xenopus Oocytes. This is a moderm pharmacological model for evaluation class Ⅲ antiarrhythmiv durgs, overcomes many defcts such as lacking human fresh cardiac muscle cells as material and co-expression of many currents on cell membrane.

Since the maintenance interval for a Combined DCB is 15 years, the replacement of double by a sectionalized single busunit,bar system is justified without availability being compromised.

由于组合式DCB 的维护时间间隔为15年，完全可以用单母分段取代双母接线，而不会降低系统的可用性。
