A first inversion triad, expressed numerically as a 6-3 chord, has its original middle note as its bass, with the original top note a third above it and the original bottom note, the root, a sixth above it. Thus the tonic triad of C major is C-E-G in root position, and E-G-C in first inversion.

三和弦第一转位用数字6-3和弦来表示，以原中间音为低音，原最高音为其上的三音，原最低音，根音，为其上的六音。C大调主音三和弦在原位为C-E-G，第一转位为E-G-C。

A second inversion triad, expressed numerically as a 6-4 chord, has its original top note as its bass, with the original bottom note, the root, a fourth above it and the original middle note a sixth above it. Thus the tonic triad of C major is C-E-G in root position, and G-C-E in second inversion inversion.

三和弦第二转位用数字6-4和弦来表示，以原最高音为低音，原最低音，根音，为其上的四音，原中间音为其上的六音。C大调主音三和弦在原位为C-E-G，第二转位为G-C-E。

It encodes a putative zinc finger transcription factor, and is a transcriptional corepressor for thyroid hormone receptors.

The reason of low system efficiency of the mechanical lifting is: unavailable match between transformer and asynchronous motor with large capacity of equipment and large self-consumption; large average no load less of Y series electrical machinery (31.4% of the total oilfield electrical machinery) with 2.86kw; limited adjustable extent of stroke of the electrical machinery in low-liquid produced wells with minimum value of 4 times per minute for limitation of minimum rotation of the electrical machinery and minimum arc of contact of pulley. Energy consumption will be waste for 1 to 1.5 times per minute is enough.

分析显示，造成抽油机系统效率低的原因主要是：变压器与异步电动机之间匹配方式不合理，设备容量大，自身损耗大；占油田电机总量31.4%的Y系列电机的平均空载损耗大，为2.86kW；低产液井电机的冲次可调范围有限，受电机最低转度和皮带轮最小包角限制，其最小冲次仅可调到4次／min，但1~1.5次／min的冲次即可满足生产需要，造成能耗浪费。
