lateral line 【動物;動物學】(魚及兩棲類的)側線(感官)。

laterality

Diagnostic characters for the recognition of species include the presence or absence of pectoral fin , the position of dorsal fin origin , gill opening , anus , nostril opening and eye , the cirri present or not , the dentition type , the body coloration , and the head pores or lateral line etc 一般依據胸鰭的有無或發達程度,背鰭起點、鰓孔、肛門、鼻孔和眼等的相對位置,頜的發達程度和頜上是否具須,齒的形狀和排列方式,身體的斑紋,以及頭部和體側的側線孔數目等進行鑒別。

( 5 ) it was more precise for using darcy - weisbach formula to calculate the hydraulic pressure slope curve in the lateral line , but too complexity . although i - pm wu formula is simple , the estimated results were not agreement with the measured data . a coefficient including irrigation uniformity was presented to modify i - pal wu formula , and the results were agreement after using the coefficient ( 4 )利用達西?韋斯巴赫公式計算微孔毛管的沿程水頭損失具有較高的精度,但計算復雜,吳義伯公式計算雖較簡單,但在灌水均勻度較差時誤差較大,為此對吳義伯公式進行了修正,提出了修正系數的計算經驗公式,取得了良好的結果,為簡易地下滴灌工程設計中水力計算建立了簡化公式。

Not only was the pattern of recordings along the artificial lateral line similar to the pattern recorded from the nerve cells of a real fish , but the computer could also decipher it to follow the source of the pulse as it moved along different paths 結果顯示不僅該系統記錄的圖形與從真正的魚身上的神經細胞所記錄的圖形相似,而且配套的電腦程序還能通過對記錄圖形的解讀來追蹤沿著不同路徑移動的脈沖水波的源頭。

With the expand of urban scope , great change have taken place in railroad hinge , many internuncial lines and lateral lines had been surrounded . former status and function had been losed , capacity of transportation is surplus 同時,隨著城市規模的擴張,我國大城市鐵路樞紐也逐漸發生了很大變化,鐵路樞紐內的許多聯絡線、支線逐漸被城市包圍,逐漸失去了原來的地位和作用,運能虛糜,設備、設施閑散。

The alteration of city and country power system will bring the power supply ability to a new level . especially , the widely use of power cable cause the capacitance to earth doubled , and a cutoff of some lateral line has comparatively larger effect 隨之而來的是電網對地電容的增大,特別是城網改造中電力電纜的廣泛應用,使電網的對地電容成倍增加,切除某一支路對整個電網的對地電容影響比較大。

( 6 ) according to the relation of pressure and discharge of different orifice aperture from the experiments . the largest available length of lateral pipes was calculated , and the combined method of varied orifice aperture and equal discharge in lateral line was discussed ( 5 )根據實測的不同孔徑的壓力流量關系,計算了允許最大毛管長度,并在理論上對變孔徑等流量毛管組合方法進行了探索。

Having proved his point , dr liu is now trying to design sensors that work more like the sense cells in a real lateral line 在自己的想法得到驗證后,劉博士目前正在試圖設計一種工作方式更接近魚類天然側線系統中感覺細胞的傳感器。

Head about 1 / 5 of its total length ; body naked , with only one row of lateral line canal scales in both side 頭長約為全長的1 5 ,骨化程度高。背鰭基寬,約為全長的1 4左右。
