心轴

As the equation of the curve determined by companion centers shows, our main result is that the set of all companion centers of a nonisosceles triangle is the unique equilateral hyperbola, called the hyperbola of , passing through the vertices ,, and the barycenter of .

透过伴心轨迹方程式我们得到主要结果如下：非等腰三角形的伴心所成的集合是一个通过三顶点、、及重心唯一的等轴双曲线，称为的双曲线。

Gynoecium of 1-5 distinct 1-loculed carpels or 2 to many partially to completely connate carpels; placentation axile ; ovules 1 to many per locule.

雌蕊群有1-5个离生1室的心皮组成，或者2到多数部分或完全合生的心皮组成；中轴胎座；胚珠1到很多每室。

With tile ovary maturing, the orifice was narrowed because of tile ovary growth at last fused completely. The gynoecium is composed of a single carpel.(1) In tile series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when tile mouth of ovary was formed.

子房由1枚心皮构成；(4)从子房发育过程的切片看，该植物的胚珠是在子房发生后不久发生的，子房上的圆孔形成时，从近轴侧的分生组织发生胚珠原基，由胚珠原基分化出珠被与珠心。

The floral primordium is initially circular, along with the edge of which slight concaves occur. The outmost whorl of tepal primordia arises as a result of apical meristem division and the floral primordium then is in the shape of triangle. Two further whorls of tepal primordia arise in spiral acropetal sequence and are alternately arranged. When the innermost whorl of tepal primordia is at the late developmental stage, the foremost stamen primordia arise almost simultaneously in spiral acropetal succession and all of the stamen primordia are ultimately arranged in a triangle-cone form. Late in stamen primordium development, carpel primordia arise as same as the young stamen primordia and grow laterally. Grooves are present on the adaxial side of each carpel and develop into ventral sutures gradually closing up.

观光木的花原基最初为近圆形，随着顶端分生组织的活动，花原基边缘处出现浅凹，形成第一轮花被片原基，此时，花原基呈三角形排列，后两轮花被片原基依次发生，与前一轮互生；在内轮花被片发生的后期，最初几枚雄蕊原基几乎同时出现，呈螺旋状向顶发生，最后排列成三角圆锥状；雄蕊原基发育后期，心皮原基开始发育，形状与发育初期的雄蕊原基相似，随后心皮原基进行侧向生长，在近轴面出现浅凹，进而发育为凹槽，形成腹缝线，最后腹缝线完全愈合。

Methods: Totally 101 patients with EH and 31 healthy volunteers were enrolled. Systolic peak velocity was measured at basal and middle segments in different left ventricular walls using real-time triplane quantitative tissue velocity imaging.

选择原发性高血压患者101例和健康志愿者31例，应用实时三平面成像技术同时显示心尖四腔心、心尖两腔心和心尖左心室长轴切面，启动定量组织速度成像模式测定左心室各壁基底段和中间段收缩期峰值速度。

Ovary superior, disk absent, locules and carpels 3-5 or more; placentation axile; ovules anatropous with a single integument, 10 or more per locule; styles as many as carpels, distinct or connate, generally persistent.

子房上位，无花盘，室和心皮3-5或更多；中轴胎座胚珠倒生，有单个珠被，每子房室有10个或更多的胚珠；花柱和心皮同数，离生或者合生，通常宿存。

Ovary 2-locular, carpels free at apex; ovules mostly 1 per carpel, less often many, but then most of them sterile, crassinucellar, bitegmic, anatropous, halfway between apotropous and epitropous, pendent from ovary top if solitary, along the carpellary margins if numerous; placentation axile.

子房2室，心皮离生在先端；每心皮多数的胚珠1，较少的通常很多，中途在apotropous和胚珠向上转之间，然而他们中大多数不育，crassinucellar，bitegmic，倒生，中轴胎座花柱和柱头2。

From the pith to the bark, vessel-elements proportion increased to the 9th ring, reaching the maximum, and then decreased; fiber proportion increased fluctuate, contrary to the ray proportion; and the parenchym proportion is in degression in juvenile wood, and increase by degrees in mature wood.

组织比量径向变异表现为从髓心向树皮方向，导管比量先增加至第9轮达最大值，以后降低；纤维比量呈波动性递增特点，与射线比量相反；枫杨轴向薄壁细胞比量径向变异主要表现为幼龄材由髓心向树皮方向递减，到成熟材以后又开始递增。

Carpels 2, rarely 3-5(-10), usually ± connate; ovary superior or semi-inferior to inferior, 2- or 3-5(-10)-loculed with axile placentation, or 1-loculed with parietal placentation, rarely with apical placentation; ovules usually many, 2- to many seriate, crassinucellate or tenuinucellate, sometimes with transitional forms; integument 1- or 2-seriate; styles free or ± connate.

心皮2，很少3-5(-10)，通常多少合生；半不如下位的子房上位或，2-或3-5-10室具中轴胎座，或1室具侧膜胎座，很少具顶端placentation；通常胚珠很多，2-在很多具薄珠心的crassinucellate或，有时具过渡形式，seriate；珠被1或2 seriate；花柱离生或多少合生。

Where other carpels to give a multilocular ovary, the marginal placentae of the carpels may fuse in the center of the ovary,giving axile placentation, as in tulip(Tulipa spp.).

某些心皮形成多室子房，心皮的边缘胎座可能在子房中央融合形成中轴胎座，如在郁金香中。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
