使不变

To avoid the influence of head position change and to overlap and compare the changing hard tissue under the skull reference system, this work set up a three-dimensional reference frame, which was based on point"S'"(the median point of the upper rear brim of the anterior wall of pituitary fossa), point"Na"and point"Ba"and of which point"S"is origin. UNISIGHT is used to get the original coordinates of all the landmarks in the MPR phase.

为消除矫治前后患者头位变化的影响，使治疗前后变化的上下颌骨和牙列以相对不变的颅底结构作为参照系统进行影像的重叠和对比，本研究通过头颅内的固有标志点S'，N，Ba三点确定了参考平面，建立了以S'点为原点的测量三维坐标系。

In the matter of redaction, it allows that "for liturgical or musical or other unknown reasons, psalms may have been split up or joined together" in course of time; and that "there are other psalms, like the Miserere mei, Deus , which, in order that they might be better fitted to the historical circumstances and the solemnities of the Jewish people, were slightly re-edited and changed by the omission or addition of a verse or two, so long as the inspiration of the entire text remains intact".

在这件事的节录，它可以让"为礼仪或音乐或其他不明原因，诗篇可能已经分裂或一起"在过程中的时间，以及"有其他的诗篇一样， miserere梅， deus ，其中，为了使他们可能会更好装到历史情况和solemnities的犹太人民，略有重新编辑和改变所遗漏或增设一个诗或二，只要灵感整个案文保持不变"。

Based on natural gas state equation and dynamic theory of natural gas migration, natural gas velocity of flow rate equation before and after temperature and pressure decreasing is fetched, and with which interface natural gas lengths in different reservoirs are calculated and the changing law of equivalent-length natural gas in migration is analyzed, whence it is discovered that migrating velocity of natural gas along tilting up reservoir is increasing inch by inch, along with temperature and pressure continuously decreasing.

由此发现，在运载层物性不变的情况下，天然气沿上倾地层向上倾方向运移的过程，是随地层温度和压力不断降低、其运移速度逐渐增大的过程，如果有后续气体的加入，会使气体长度增大，致使运移速度增加得更快。

Similar results emerged from brain-scanning experiments by Paul Smeets , a neuroscientist at Utrecht University Medical Center in the Netherlands, in which he fed volunteers two versions of an orangeade drink. One was sweetened with sugar and one with a blend of the non-calorific sweeteners aspartame, saccharin, cyclamate and acesulfame potassium.
