2) diamond mesh
菱形网目
1.
In order to assess the size selectivity for fishes of beam trawl fishing in offshore of the East China Sea,experiments of codends with different mesh configuration,including diamond mesh,square mesh and turned through 90° diamond mesh(T90) in 4 sea trials have been carried out and catch data were collected by comparative fishing method.
为评价东海近海桁拖网渔具对主要鱼类的尺寸选择性,使用对比作业法,在吕四渔场开展了4个航次的、不同网目结构网囊(菱形、方形及横向使用的菱形网目)的选择性试验。
2.
In order to improve size selection for shrimps of multi-codends beam trawls fishing in offshore of the East China Sea,experiments of several sea trials for size selectivity of codends with different mesh configuration, including diamond mesh,square mesh and turned through 90° mesh,have been carried out and catch data were collected by comparative fishing method.
选择性模型对哈氏仿对虾(Parapenaeopsis hardwickii)和葛氏长臂虾(Palaemon gravier)渔获数据的拟合结果显示,选择性模型具有较好的拟合性,但存在航次间差异;不同网目结构网囊的选择性曲线模型都可简化为Logistic曲线;对于哈氏仿对虾,相比菱形网目网囊,方形网目和转向网目网囊的L50较大,而SR较小(菱形和方形网目之间差异显著,菱形和转向网目之间差异不显著);对于葛氏长臂虾,方形网目和转向网目网囊的L50较大(菱形和方形网目之间差异显著,菱形和转向网目之间差异不显著)。
3.
The selectivity of square and diamond mesh codends with different mesh sizes (25mm, 30mm, 35mm, 40mm and 45mm) of two-stick swingnet was analyzed through covernet method selective experiments, in which Logistic curve was regarded as the selection curve and the maximum likelihood method as estimation method of the parameters of selectivity model.
使用套网法作为选择性试验方法,Logistic曲线作为选择性曲线模型,并运用极大似然估计法进行曲线参数估算,对桁杆张网渔具不同网目尺寸(25mm、30mm、35mm、40mm以及45mm网目大小)、不同网目形状(菱形网目和方形网目)的网囊选择性进行分析。
3) rhombus structure
菱形结构
1.
Relationship between the rhombus structure and evaluation of arbitary degree raising is shown, variation diminishing properity is proved again based on rhombus structure.
本文的主要结果是提出了菱形结构,构造出广义的Ball样条曲线和曲面,给出它们的任意阶升阶公式,并证明了变差缩减性质。
4) Rhombic stall
菱形结构矿房
5) rhombus wave
菱形波面结构
6) double diamond knot
双花菱形结节

目（目巟）（目巟） 目（目巟）（目巟） 证名。出《素问·藏气法时论》等篇。《太平圣惠方》卷三十三：“视物昏暗，故谓之（目巟）（目巟）也。”《素问·藏气法时论》：“肝病者，……虚则目（目巟）（目巟）如无所见，耳无所闻，善恐，如人将捕之。”又《灵枢·经脉》：“肾足少阴之脉，……是动则病坐而欲起，目（目巟）（目巟）如无所见。”说明肝肾受病均能引起视力减退，目视（目巟）（目巟）。治宜补肝明目，滋补肝肾。方用青羊肝散、一贯煎加减。参见目昏条。
