Because hsg is associated with sinus tract, the embryologic origin of hsg in the lower neck may be from the branchial apparatus
因為下頸部異位性唾液腺常伴隨管竇腔，所以其胚胎的來源可能是鰓弓器。In case 6, the heart looks " inverted " compared to normal ( figure 8 ). this phenomenon is called dextrocardia, and it results from a looping anomaly during embryologic development
病例6中的心臟與正常相比看上去就像「反轉」了一樣（圖8 ） ，這稱作右位心，是由於胚胎發育過程中的心臟成環異常導致。After analyzed the basic principle of optimized noise reduction on tyre pattern, summarized three approaches to noise reduction. the first is trying to reduce size of single block or socket to reduce noise amplitude on time domain, the second is to adjust stripes sorting order and their interlace value to avoid noise - made by every single block - peak values on time domain overlayed and the last is to adjust ratio of blocks and sockets, ratio of stripe interval and stripe sorting order to avoid noise periodical distribution and abnormal high peak values in some frequency strip
論文第四章分析了輪胎花紋優化降噪的基本原理，總結出三條降噪途徑：在允許范圍內盡量減小單個塊或槽的大小、刻刀槽軟化花紋塊來減小噪聲時域波幅度；調整節距排列順序、花紋條之間的錯位值，使各發聲單元發出的聲壓時域波形的同向峰值錯開，避免同向峰值疊加；調整花紋塊和槽比例、節距比例、節距排列順序，盡量避免周期性分佈，使輪胎所發出的噪聲趨于白噪化，避免某些頻段的異常高峰值。
