An annual is best known as a plant that completes it's life cycle in a single season. Hardy annuals can survive cold temperatures and some light frost, while tender annuals cannot tolerate cold temperatures and should be planted only after there is no more danger of frost. Half-hardy annuals can tolerate some cold temperatures, but are usually killed by frost. Annuals make excellent space fillers for the perennial garden.

一年生植物最显著的一个特点就是它在一个季节内完成它的生命轮回，耐寒的一年生植物能够在低温和轻微霜冻的条件下生存，但是幼嫩的一年生植物不能忍受低温，他们只能在没有霜冻危险的条件下种植，半耐寒型一年生植物能够经受一些低温条件的考验，但是通常他们因为霜冻死亡，一年生植物能够为多年一成不变的庭院创造一个很出色的空间。

Sensitivity function and control sensitivity function are obtained by Youla parameterization of controller,which is used to describe an integral square performance criterion containing tracking error and control energy.

由控制器Youla参数化得到控制系统的敏感度函数和控制敏感度函数用来表示一个包含跟踪误差和控制能量在内的积分平方性能指标，针对不同类型的时滞过程运用谱分解的方法最小化该性能指标，从而导出相应控制器的设计方法，可使系统在控制能量约束条件下具有最优的控制性能。

An integral square performance criterion containing tracking error and control energy was defined. Spectral factorization to minimizing the performance index for different systems was applied and corresponding parameter tuning methods of PID controller was derived, which could be used to obtain optimal control performance under control energy constraint.

定义了一个包含跟踪误差和控制能量在内的积分平方性能指标，针对不同系统运用谱分解的方法最小化该性能指标，从而导出相应的PID控制器的参数整定方法，可使系统在控制能量约束条件下具有最优的控制性能。

The problem of invariance is both important and difficult in studies of neural retworks.

对不变性的认识，特别是对变换群下的不变性的认识，一直是神经网络系统研究中最重要的也是最困难的问题之一。

Despite ready access to the sea food, Liguria's best-known food is land-based in origin. Focaccia, the locals' answer to pizza, is right-angled cuts of tasty bread made with little more than flour, salt, olive oil and a few extras than vary depending on which town along the Italian Riviera you visit. The tastiest type hails from Recco, where Stracchino cheese ( Stracchino is a type of Italian cheese, typical of Lombardy which derives from the Italian word "stracca", meaning "tired". It is said that the milk from tired cows is richer in fats and more acidic. It is eaten very young, has a soft, creamy texture and normally a mild and delicate flavour. It is normally square in form.) gets sandwiched between two layers of bread and then served piping hot. Those not keen on stand-up lunches among the sun-lotioned throngs have plenty of alternatives though as rustic eateries are plentiful around Santa Margherita Ligure.

在乐乔亚区虽然海产唾手可食，可是最吸引人的美食还是当地类似 Pizza 整齐切片的 Focaccia 面包，口味与配料延著义大利 Riviera 地区而异，主要是由面粉、盐、橄榄油与洋葱等额外配料烤成，最美味的是来自 Genova 省 Recco 区的 Stracchino 起司夹心热三明治( Stracchino 起司是 Lombardy 地区的典型起司，Stracchino 源自义大利文"stracca"，原意是疲倦，产自疲倦乳牛的牛乳据闻更富脂肪与酸性；趁鲜食用，乳脂柔软富香气，以块状包装)，它并非渴望在艳阳下囫囵吞枣的五脏庙祭品，但环绕 Santa Margherita Ligure 地区却有许多乡间小馆可让大家选择。

To analyze the response of pavement structure under moving loading, a quarter vehicle model with single freedom degree and unevenness model are established. The dynamic loads are calculated through combining different pavement conditions and speed. When the incentive frequency which is passed to vehicles by the road is close to its own vibration frequency, vehicles will produce the greatest dynamic load.

为了分析路面结构在行车动荷载作用下的力学响应，建立了单自由度1/4车辆模型和以正弦曲线模拟路面不平整度的模型，通过将不同路面状况和行车速度的组合，分析车辆在各情形下所产生的动荷载，发现路面传给车辆的激励振动频率接近车辆自身振动频率时，车辆对路面产生的动荷载值最大。

Because of the slip speed will change when the voltage of VVVF is changed, so we can control the slip speed by controlling the outport voltage of VVVF, A saving energy method of main driven motor of CNC machine tool which running in the defferent state of load is introduced in the paper .This method is realized by optimizing the slip speed in the defferent load state based on the adaptive neural network.

根据电机的转差率的变化，通过调节变频器装置的输出电压来控制电机运行转差率，并基于神经网络模型参考自适应的控制算法实现了交流异步电动机在不同负荷下最优转差率的控制，从而达到电机在不同负载下的节能运行。

It seems to me the worst comment on dictatorships is that presidents of democracies can laugh, while dictators always look so serious—with a protruding jaw, a determined chin, and a pouched lower lip, as if they were doing something terribly important and the world could not be saved, except by them.

在我看来，对于独裁统治最尖锐的批评莫过于：民主制度下的总统会笑，而独裁者却总是一脸严肃——向外突出的颌骨，硬梆梆的下巴，弯成袋状的下唇，似乎他们在做着非常了不得的事情，只有他们能拯救世界。

To take advantage of the chaotic mapping, a repetition prepotency evolution algorithm with a population initialized by chaotic numbers is developed in which the chaotic mapping is an uncommon seeding-machine to produce different initial'chromosome'populations never appeared before for PE algorithm. The combination of chaotic mapping and PE makes PECA be able to probe lots of optima rapidly and effectively owing to the quick convergence speed of PE and relatively high population diversity guaranteed by chaotic mapping.

结合混沌来初始化优势进化算法的群体成员，还设计了基于混沌初始化群体成员的循环优势进化方法，该方法在混沌保证每次优势进化绝对不同的初始群体成员的情况下，不仅具有了优势进化的快速收敛优点而且有混沌映射保证群体成员的高度多样性，从而可以快速探测很多局部最优点，大大提高了找到全局最优点的机会，用它训练神经网络预测四卤化物振动频率研究充分体现了该策略的优越性。

A responder's rebid of the cheapest two of an unbid minor is artificial, forcing, and promising at least game-invitational strength opener's priorities over such a bid are: show three-card fit for responder's original suit, show four-card length in the unbid major, show a minimum with the cheapest other bid, show a maximum descriptively with anything else; responder's next bid is forcing unless it is two of his original suit, two notrump, or a raise to three of the major just bid by opener

a应叫者的二阶最便宜的未叫低花再叫为人为，逼叫，且保证至少有邀请成局的力量开叫者再叫的优先级为：以3张支持应叫者的第一次花色，叫出未叫高花保证4张，叫其它最便宜的花色为示弱，叫以上未提及花色为示强；应叫者的下一次叫品为逼叫，除非是二阶自己原花色、2NT、或三阶加叫开叫花色。
