心轴

In Nymphaea, 4 sepal primordia initiated from abaxial to adaxial side of the floral apex. Petal and stamen numerous, initiated in spirals. The apex of floral primordium caved in at the late stage.

For the tetracene overlayer near to a monolayer, formation of a parquet-like pattern was observed.

当分子长轴取向垂直于[1-210]方向并且其质心位于密排原子列上两个Ru原子的短桥位时，该位置是它的次佳吸附位，在该位置的吸附能为4.19 eV。

Afterwards,sexual activity and attached NO content of endothelium cell of penial corpus cavernosum were obverved.

Through Hilbert transform, a signal's plane trace can be get. There are two frequencies in the tested signal, so the signal's plane trace may be looked as the track of the out pole's end when two poles rotate around parallel axles. Using the knowledge of motion synthesis in theory mechanics, a formula to describing the change of plane trace's step length and angle for two-frequency be get. So we may prolongate the tested signal's plane trace from the echo's initial arriving moment, and get a certain length of the signal's prolongation.

通过Hilbert变换可得到测试信号的平面迹线，测试信号中只含有两个频率成分，视为双频信号，双频信号的平面迹线相当于两连杆绕平行轴转动时外杆杆端迹线，利用理论力学中运动合成和瞬心知识，推导出双频信号平面迹线步长平方满足余弦线性复合函数，而迹线转角可视为线性变化，据此可对回波到来之前的测试信号平面迹线作延长，得到一定长度的信号延展段，信号延展段与实测段作差可得到一次、二次回波的第一个波峰值。

Styles and stigmas 2. Fruit a capsule, dehiscing septicidally, septifragally, or loculicidally and 4-valved; endocarp woody or leathery, usually loose from leathery exocarp. Seeds 1 to many per carpel; if solitary then seed coat thick, hard, smooth and shiny, black or brown; if numerous then sometimes winged and only a few viable.

蒴果，室间开裂，室轴开裂，或者室背开裂和4瓣裂；内果皮木质或革质，通常从革质外果皮中释放种子1到多数每心皮；如果单生那么种皮厚，坚固，光滑并且发亮，黑色或者棕色；如果多数那么有时具翅并且仅仅少数几个有生存力。

The main characters of this category are: 1 It possesses clear main axes and lateral branches/sporangial stalks; 2 Sporangia terminate the lateral branches or long stalks; 3 With the distinct dehiscing mechanism, the sporangia have the variation in shape, i. e. reniform, rounded or vertically elongate; 4 Primary xylem is of centrarch maturation; 5 Conducting tracheid is G-type.

该类群包括Hsüa，Renalia，Nothia，Sartilmania和Huia，其主要特征为：1）具有明显的主茎轴及侧出的分枝系／孢子囊柄；2）孢子囊顶生于侧枝上或侧生的长柄上；3）孢子囊性状存在变异，为肾形、圆形或纵向伸长，具明显的开裂机制；4）初生木质部发生顺序为心始式；5）G-型输水管胞。

Quantitation of the ventricular systolic and diastolic functions in the longitudinal axis is clinically relevant since the contraction of the ventricle in this direction is mainly due to subendocardial fibers.

心室长轴方向上的收缩和舒张由心内膜下心肌纤维的运动引起，可客观反映心脏整体舒张和收缩的程度。
