查询词典 change point

The first rank derivative is a reflection of curve change and its rate, at certain range, if the sign of the first rank derivative has changed, the logging value of the correspondence depth point means maximum in this range; the second rank derivative is the knaggy property reflection of curve, at certain range, if the sign of the second rank derivative has changed, the correspondence depth point represent the inflexion of geophysical logging curve, it＇s also a turning point of the reflection of knaggy change property of the curve, it is the interface of stratum.

测井曲线的值是深度的函数，测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢，在某一范围内，当一阶导数呈现符号转换时，相对应的深度点的测井值即为该范围内极大值；测井曲线的二阶导数则表示曲线的凹凸性，在某一范围内，当二阶导数呈现符号转换时，相对应的深度点代表了测井曲线的拐点，即反映曲线凹凸性变化的转折点，亦即地层的分界面。

将南黄海概化为一等深矩形海疆，初阶研究了在海平面上升3m 和 5m 前提下该海疆扭转潮波体系的演化趋势，继而剖析了沿岸潮差厘革特性。初阶分析研究剖明：跟着海平面上升，该海疆 M2 分潮的无潮点有向东南标的目的偏移的趋势，受此影响，沿岸潮差泛起差此外厘革特性，接近无潮点的左侧及湾顶海岸厘革较着，而阔别无潮点的右侧及湾顶海岸则厘革不年夜。

Transcript level was not obviously different between MSTN and IGF2. The expression of MSTN reached the highest point at 7 day and droped to the lowest point at 7 weeks after birth. The expression of IGF1 arrived at the highest peak at brith, and degraded the half of the birth after 7 days. Then, the change of the IGF1 expression level was no abvious. The expression result of the IGF2 decreased to the least at 1 week and increased the max point at 3 weeks. The change regulation of IGF2 expression was showed as a wave.

其中，IGF-1表达水平最低，MHC2a表达水平最高；IGF2与MSTN表达水平相当； MSTN的表达于7天时表达水平最高，是出生时表达的3倍，随后于14天时急剧下降，于7周时降至最低水平；出生时IGF1的表达水平最高，随后于一周时降至出生时的一半，后期的表达变化不大； IGF2的表达水平于3周时表达最高，是出生时的两倍，在1周时最低。3周后骤然降低，呈现一个波浪型变化；MHC的表达出生时最高，于1周后降至原来的1/7，随后逐渐升高，但变化并不太大。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
