From the theory, the algorithm for determination of the degree of implicit polynomials is followed: detecting the stationary points in the object boundary based on its features, and then calculating the minimum degree according to the formula derived from the theorem. In addition, the theory can be extended to three-dimensional object.

风险预算的目标就是，在投资者可以接受的风险水平下获得最大的收益。

Simulation result for an actual boom shows that the incremental equations, derived from infinitesimal increment, can be used widely, and the computational error makes a slightly trajectory deviation from reference straight line, which would not influence the final position, which is important in actual situation.

针对某实际钻臂的仿真结果表明，增量算式尽管是在微变情况下推导的，在偏差较大的范围内应用时其计算误差对定位过程影响不大，体现在钻臂轨迹于隧道断面的投影不是直线，同时不会影响最终的控制精度，可以用于实际控制。

The simulation result for an actual boomshows that the incremental equations, derived from infinitesimalincrement, can be used in large variable range, and the computational error makes a slight trajectory deviation from reference straight linewhile makes no final positioning error, which is important in actualsituation.

仿真结果表明，本文提出的算式是正确的，控制系统结构是合理的；增量算式尽管是在微变量情况下推导的，在大的运动范围所带来的误差不大，适于工程应用；实现了双三角臂运动驱动的动态解耦。4。

Seven types of dimetric drawing and three types of trimetric drawing are introducedby the author with an aim to help hasten the shift of the principles derived from varioustypes of dimetric and trimetric projections from the theoretical approach to the field ofpractical use,and to alleviate the embarrassing situation that only the simple methodscan be resorted to in drawing the pictorial projections by isometric drawing and cabinetdrawing.

为了使各种形式的正二测和正三测从理论研究转向实际应用，克服长期来人们在绘制轴测图时，多数只能采用正等测和斜二测等单调情况，以及提高绘图速度，本文推荐采用七种正二测和三种正三测，并设计一套绘制这十种正轴测的专用工具--轴测多角比例尺。本文提出一套近似作这十种正轴测坐标面上椭圆的方法和数据，使其既简便又准确。

The fundamental equations derived from these two models are different and they can not be converted from one to another.

各模型本身也存在一些缺陷。这些都是由于对多相流的随体导数不恰当运用引起的。

Hippolytus tried to prove that all Gnosticism was derived from heathen philosophy; his speculations may be disregarded, but, as he was in possession of a great number of Gnostic writings from which he quotes, his information is priceless.

西波吕试图证明，所有诺斯替主义来自异教徒的哲学，他猜测可能会被忽视，但是，因为他拥有大量的诺斯底著作从他报价，他的信息是无价的。

The solitary wave can be generated considering Goring and Raichlen's movement of a paddle. The proposed original linear solution for the solitary wave generation is expressed in the hypergeometric function. Two disadvantages of the original solution with large trailing wave and skewed wave profile are found by comparing with the theory of solitary wave derived from Boussinesq's equation. The difference between the original linear solution and the solitary wave theory results from the nonlinearity and dispersion of generated waves in the flume.

本文并以弱非线性的孤立波造波问题做为解析之对象，由於孤立波造波板速度为一超越函数，造成解析上的困难；本文以 hypergeometric 函数推求常微分方程式之全解，并与理论波形解比较后，发现由於未考虑非线性及分散性过强等问题，使得线性暂态解较理论波形拉长与歪斜，可能无法有效描述孤立波造波问题，故针对线性之分散关系做出修正。
