使用由太阳光学望远镜/分光偏振仪上的Hinode卫星观测到的数据，水平和垂直场来自塞曼引起的线偏振和圆偏振的波长积分措施。安静的内部网络区域被水平磁性元素所弥漫。我们将水平网内磁性元素分为两类：一类是非孤立元素，在演化过程中伴随着垂直磁性元素;另一类是孤立元素，不伴随着垂直磁性元素。研究了它们的寿命、尺寸和磁通密度等性质，并研究了各种磁性参数之间的关系。共识别出446个水平内部网络磁性元件，其中87个为隔离元件，359个为非隔离元件。定量测量表明，孤立元件具有相对较弱的水平磁场，几乎相同的大小，和较短的寿命相比，非孤立的元素。大多数非隔离的水平内联网磁性元件被确定为与Ω形磁通回路的出现相关联。一些非孤立的元素似乎表明Ω环的淹没或U型环的出现。隔离和非隔离水平网内场单元（HIF）的寿命与尺寸之间存在正相关关系。对于非孤立的HIF，寿命与磁通密度之间也存在正相关关系，而对于孤立的HIF，寿命与磁通密度之间不存在相关关系。尽管水平元素的磁通密度较低，但它们每天可以携带接近1025 Mx数量级的总磁通量到太阳表面。
Using the data observed by the Solar Optical Telescope/Spectropolarimeter aboard the Hinode satellite, the horizontal and vertical fields are derived from the wavelength-integrated measures of Zeeman-induced linear and circular polarizations. The quiet intranetwork regions are pervaded by horizontal magnetic elements. We categorize the horizontal intranetwork magnetic elements into two types: one is the nonisolated element which is accompanied by the vertical magnetic elements during its evolution; another is the isolated element which is not accompanied by the vertical magnetic elements. Their properties, such as lifetime, size, and magnetic flux density, are studied, and the relationships among various magnetic parameters are investigated. We identify 446 horizontal intranetwork magnetic elements among them 87 elements are isolated and 359 are nonisolated. Quantitative measurements reveal that the isolated elements have relatively weaker horizontal magnetic fields, almost equal size, and shorter lifetime compared with the nonisolated elements. Most nonisolated horizontal intranetwork magnetic elements are identified to associate with the emergence of Ω-shaped flux loops. A few nonisolated elements seem to indicate scenarios of submergence of Ω loops or emergence of U-like loops. There is a positive correlation between the lifetime and the size for both the isolated and nonisolated horizontal intranetwork field elements (HIFs). Positive correlation between the lifetime and the magnetic flux density for nonisolated HIFs is also found, but no correlation for isolated HIFs. Even though the horizontal elements show lower magnetic flux density, they could carry the total magnetic flux in the order of magnitude close to 1025 Mx to the solar surface each day.
