The results show that : l ) there are three anomalous high temperature areas and three anomalous low temperature areas, and the whole area high temperature anomaly took place in the late 1980s, whereas the low temperature anomaly in the 1970 ; 2 ) the spatial mode manifests identical variations in the whole area, and the temporal coefficient curve is of 2 - 3 year period oscillation and an interdecadal abrupt in the late 1970s ; 3 ) the variance of interdecadal component is obviously larger than that of interannual in the most part of nespa ; 4 ) the interdecadal variation of the temperature is mainly linear ascendance in the late 1970s, the large range anomalous high ( low ) temperature occurs when the interdecadal and interannual anomaly are both positive ( negative ) in the year ; 5 ) the temperature anomaly is divided into four patterns : southern, northern, eastern and western patterns, in which the interdecadal variation of the southern and western patterns is relatively importance and the interannual variation of eastern and northern pattern is relatively importance

Using the hprt gene as a positive control, our result suggested that both the testis tissue and the male embryos from which sry transcription can be detected failed to yield any positive results of xist. female embryos at the pronucleus stage and 2 - cell failed to produce any positive result of sry and xist too. while since the 4 - cells period, xist is constantly transcribed until blastocyst stages

本文的主要工作和結論如下：在人工氣候室內，根據不同覆冰絕緣子正、負極性下的閃絡試驗結果，得出負極性電弧金屬陰極的強電子發射能力造成了單片瓷、玻璃絕緣子及被冰凌橋接的合成絕緣子有較低負極性冰閃電壓；正極性電弧金屬陽極側產生高電阻區所處位置的差異使得瓷和玻璃絕緣子串具有明顯的極性效應；覆冰較少時，合成絕緣子表面出現數量較多的非極性電弧使合成絕緣子無極性效應。利用覆冰期內平均閃絡電壓的試驗方法，對不同材質和結構的絕緣子在覆冰、低氣壓和污穢共存環境中的直流閃絡特性進行了研究。試驗結果表明，直流平均閃絡電壓隨著海拔的升高、覆冰量的增加以及污穢度的增加而降低，且其特徵指數與絕緣子結構、覆冰量、覆冰狀態、污穢度等有關。 -
