InSection 2,we give several sufficient conditions for the existence of one solution,multiplesolutions and infinitely many solutions of the Sturm-Liouville bvps via the generalizedpolar coordinates.Then in Section 3,the existence of positive solutions are proved undersuperlinearity,sublinearity and many other conditions by a fixed point theorem in cones.Our results have generalized those in many articles.A detailed discussion of periodic solu-tions of a kind of functional differential equations with high-order Laplacian-like operatorcan be found in Section 4 and this subject has not been studied before.

在第二节，我们定义了一种新的坐标变换-广义极坐标，并利用它讨论了p-Laplacian算子和Laplacian-型算子的Sturm-Liouville边值问题，分别得到了存在一个解、多个解、无穷多个解的多个充分条件；第三节研究p-Laplacian算子的Sturm-Liouville边值问题正解的存在性与多重性，采用的是锥上的不动点定理，全面推广了这一方面已有的结果；对目前研究较少的高维Laplacian-型算子及带有Laplacian-型算子的泛函微分方程的周期解问题，我们在第四节做了一些研究，这也是拓扑方法的一个应用。

Any of various evergreen trees or shrubs of the genus Juniperus, having needlelike or scalelike, often pointed leaves and aromatic, bluish-gray, berrylike, seed-bearing cones.

桧属植物，杜松任何一种桧属的常青乔木或灌木，有针状或鳞状的尖叶和气味芳香、色泽蓝灰、形状象浆果、含种子的球果

In order to clearly understand the dynamics mechanism about broad-leaved Korean pine forest and simulate its dynamics mechanically, a simulation model is demanded through which we can simulate the long-term dynamics of BKPF under different pine cones picking intensity and hunting for grey squirrels in different intervals. By considering the effective dispersal of seeds by animals, the human disturbance and the masting behavior of Korean pine, a new gap model integrated seed-bank and regeneration dynamic model, based on the classical gap model, is established.

为了能够充分理解阔叶红松林的动态机制，准确模拟东北阔叶红松林的动态变化，探索出既能够保护好又能够利用好阔叶红松林的新途径，根据阔叶红松林的动态机制，在经典林隙模型的基础上，添加考虑了阔叶红松松林中动物对种子的有效传播、人工采摘干扰以及红松的结实特性，建立了红松种子库及其更新的动念模型更新子模型，使模型更能够反映阔叶红松林中的动态机制。

Gnetophyta A phylum of gymnosperms with compound cones, cells in the secondary xylem almost identical to angiosperm vessels, and the tendency for the tip of the nucellus to be drawn out into a micropylar tube; there are no resin canals.

买麻藤门：是裸子植物具复合球果的一纲。

Noncollinear second-harmonic-generation processes involving an unfocused laser ham and itS scattered radiation produce one or more cones of phasematched second harmonic.

激光束与其散射光束在晶体中发生非线性和频作用，在满足非共线相位匹配条件时，可观察到二次谐波环的现象。

Seed cones ellipsoid-cylindric, 2.5-4 cm; seed scales obtriangular- or reniform-orbicular, densely long hairy abaxially; short branchlets densely yellow hairy; leaves 1.2-3.5 cm, keeled on both sides

球果椭圆形圆筒状，2.5-4厘米；种鳞倒三角形或肾形球状，浓密长毛背面；浓密的短小枝黄有毛；叶1.2-3.5厘米，龙骨状的两面 4 Larix mastersiana 四川红杉

The ovulate of pines are much larger and more complex in their structure than are the pollen-bearing cones (Figure 20-23).The ovuliferous scales,which bear the ovules, are not simply megasporophylls.

那松树排卵更非常大而且更多复杂的在他们的结构比较是举止花粉的圆锥体(图 20-23)。ovuliferous 刻度，忍受 ovules，不只是 megasporophylls 。

Leaves directed forward and closely appressed on upper side of branchlets, spreading and almost pectinately arranged on lower side, not parallel sided; seed scales at middle of cones obovate-oblong or rhombic, distal margin usually recurved, sometimes elo
