四分叉的

In this design, the dimension M of the memory vector field may be not necessarily equal to the dimension N of the network vector field. This may be the usually case in applications. Designing a network with either static or oscillating behavior, after analysing the dynamical. behavior of its four-dimension subspace, we get 2-torus in the subspace. If we vary the ratio of the imagine parts of the complex conjugate eigenvalues, the periodic motion of all kinds of period ratio on 2-torus are obtained.

设计一个既具有静态平衡点又具有动态振荡的网络，其静态平衡点由多余维叉形分叉得到，动态振荡形式由多余维Hopf分叉得到，通过对其中一个具有振荡行为的四维子空间的进一步分析，可以得到网络在四维子空间中的二环面运动，适当调整约当形中共轭复特征根虚部的比值，可以得到各种周期比的二环面上的周期运动。

Using nonlinear rotor bearing systems as example, the correctness and effectuation of these methods is illustrated.

本文对转子轴承系统的稳定性分叉问题进行了研究，主要工作包括以下四个方面。

Inflorescence development was divided into four stages, the initiating expansion pseudobulb, initiating inflorescence (1-3 cm in flower stalk length), the initial-branching flower stalk, and full bloom inflorescence, respectively. The activity variations of mannan cleaving enzymes,-mannosidase (EC 3.2.1.25), endo--mannanase (EC 3.2.1.78), and the mannan synthesizing enzyme, GDP-mannose pyrophosphorylase (EC 2.7.7.13), were analyzed during different stages to better understand the role of mannan-metabolizing enzymes during inflorescence development of the Oncidium.

将花梗发育过程分为四个阶段，分别为假球茎刚膨大、刚抽梗（花梗长度约1-3公分）、花梗刚分叉以及花盛开，分析参与分解甘露聚醣之酵素－β-mannosidase（EC 3.2.1.25）及endo-β-mannanase（EC 3.2.1.78），与合成甘露聚醣之酵素－GDP-mannose pyrophosphorylase（EC 2.7.7.13），在不同阶段假球茎内的活性变化，了解在花梗发育过程中代谢甘露聚醣之相关酵素所扮演的角色。

See Plate 4 in Weste and Eshraghian for another example of legged transistors (the transistors connectedto the pad are legged by a factor of four; a note to this effect appears at the bottom of the plate).

课本彩色图四也是分叉电晶体的另一个例子(连到接脚的电晶体被分叉成四个，这个效应的注解写在图页的下方)。

Zhuhai to Hong Kong Customs and Excise Department after the building is a road leading to the island of Gaolan River, through an embankment Fencha Lu, three or four hundred meters to the right side of the line is the purse Terminal Island, is to fly to the left of the beach .

珠海港的海关大楼后就是一条通往高栏岛的行车大堤，走过大堤就是一个分叉路，向右边行三四百米就是荷包岛码头，向左是去飞沙滩的。

Or, if someone has a natural intelligence for understanding the ways of the world, we may say that person has "horse sense", like a trusty four-legged friend who always knows which way to go when it comes to a fork in the road.

又如，如果某人天生聪慧，可以明了沧桑世事，我们就可以说，这个人有&horse sense&，就像一只可以信赖的&四腿伙伴&那样，总是在道路分叉时知道走向何方。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
