例句與用法
- 4 . the smooth condition for discrete series is studied , and some mistakes about the white exponential law is pointed out . the author proposes the modified condition of white exponential law which makes the data to apply the gm model
4 ?研究了灰色系統(tǒng)理論中的關(guān)于離散數(shù)列的“光滑性條件” ，指出其原寺有的“白指數(shù)律條件”的局限性，提出了新的修正型白指數(shù)律的條件，從而為數(shù)據(jù)應(yīng)用灰色系統(tǒng)模型提供了檢驗(yàn)方法。 - The study results show that the minimum ac flashover voltage decreases with the increase of the ice amount accreted on the insulator surface by an exponential law , and the down - trend of the minimum ac flashover voltage will slow gradually with the bridging of the shed of the insulators by icicles , both the average saturated ice amount and the special exponent m of effect of ice amount for different insulators depend on the radius of shed and the air - gaps of the sheds of the insulators , and that the ac ice flashover voltage decrease with the decrease pressure ratio p / p0 ( rise of the altitude ) by power - law for different esdd and icing - states when the altitude is from 4000m to 5500m . the special exponent n , which show the effects of altitude on the flashover voltage , is various with the type of insulator , icing - states and the surface status of iced insulator etc . , and that the minimum ac flashover voltage of iced insulators decreases by power - law with esdd or the freezing water conductivity for different ice amount and atmospheric
研究結(jié)果表明：在不同海拔高度和等值鹽密esdd下，絕緣子的最低交流冰閃電壓均隨覆冰量的增加而呈指數(shù)規(guī)律降低；當(dāng)覆冰量增加到一定程度后，最低交流冰閃電壓隨覆冰量增加而降低的趨勢趨于飽和；不同絕緣子串的平均飽和覆冰量及閃絡(luò)電壓的覆冰量影響特征指數(shù)m均與絕緣子的盤徑和傘距等因素有關(guān)；在海拔4000 5500m之間，不同等值鹽密esdd和覆冰狀態(tài)下，絕緣子的交流冰閃電壓隨海拔高度的增加(氣壓的降低)與p / p0呈乘冪關(guān)系降低，氣壓影響特征指數(shù)n與絕緣子類型、覆冰類型、覆冰表面狀況等因素有關(guān)；當(dāng)覆冰量和氣壓一定時(shí)，絕緣子的最低冰閃電壓均隨著等值鹽密( esdd )或覆冰水電導(dǎo)率的增加而呈乘冪關(guān)系降低，并逐漸趨于飽和。
