查询词典 twice differentiable function

In order to be able to transmit a variable volume of data, particularly in a single coherent data block, between message transmission planes of telecommunications interfaces of a hybrid telecommunications system with minimal effort within the message transmission planes, if the variable data volume exceeds the maximum data volume which can be transmitted between the same message transmission planes of the telecommunications interfaces, then a data element specific to the transmission layer is used as a function of the varying data volume at least twice in succession for the transmission of the data volume in the data block.

要約 为在混合通信系统中能各自以最小的传输工作量在各通信传输层面中传输混合通信系统各通信接口的通信传输层面之间的一个变化的数据量，尤其当此变化的数据量超过在各通信接口的相同通信传输层面之间最大可传输的数据量时仍能在一个单一的互相关联的数据块中传输此变化的数据量，取决于此变化的数据量至少两次依次地对在数据块中的数据量的传输采用一种传输层面专门的信息元素。

A nice awkward little function. The interesting thing for our example is the way the variable acc is set twice. It has two responsibilities: one to hold the initial acceleration caused by the first force and another later to hold the acceleration with both forces. This I want to split.

一个很有意思的简单函数，值得注意的是我们的例子中，变量acc被赋值了两次，这说明它有两个职责，一个用来存储因为第一个力而产生的加速度，后面一个存储两个力产生的加速度，这就是我要拆分的地方。

It has the same style with LTHS100E, however, its functions were improved based on the old style; at present, LTHS100B applies imported wind pump assembly which has twice theme ---absorb and blow (increase parts on positive pressure air, strengthen the pressure that can deliver the unmelted flux directly into little hopper); the height of material absorbing and delivering can reach as high as 5 meters, and its level distance is around 12 meters, and the capacity of flux depends is 80KG; the suspended function also can be tailored according to customers' requirements; the weight of 100B is 130KG, its outer dimension is 450*800*1100mm. It has the advantages of small-volume, light-weight, beautiful-outer-appearance, unnecessary of air-compression, and can be ground-mounted or suspended; it is also easy to be operated, with switching on button, it can be operated. Furthermore, it is controlled by infrared ray. It has alarming lights.

该机与LTHS100E机形相同，但其主要特点：在LTHS100E的基础上精心整改了其功能，现LTHS100B是采用进口风泵总成为基础，吸、吹二次全部为主题（在正压气上增加了部件，增强了压力把吸收回来没有融化的焊剂直接推送到前方机头的小料斗内，）焊剂的吸、送料其高度不得超过5米，水平距离在12米左右，焊剂容量为80KG，可悬挂也可根据用户需要为用户量身订制，自重为120KG，外型尺寸为：450*800*1100mm，本机具有体积小，重量轻，外型美观，不需要具备压缩空气，可落地、可悬挂灵活，其操作简便为一线通即可，红外线控制，上方有警示灯显示，当焊剂不足时就会报警。

WE could debase the permeability of capillary vessel of inflammatory tissue in some degree, and show a complete inhibitory effect on the edemas induced by Freund"s adjuvant complete and there is no obvious inhibitory effect found on edemas induced by carrageenan; WE indicates an obvious protective effect on the "twice-hit animal model of acute lung injury in rats induced, by oleic acid and lipopolysaccharide from lung edema. It also shows an excellent inhibition function on the chronic granuloma as well.

结果表明： 1。工蜂胎的水提物能够在一定程度上降低炎症区域毛细血管的通透性，能够抑制完全弗氏佐剂引起的炎性肿胀，对角叉菜胶引起的炎性肿胀效果不明显，对油酸加LPS两次打击所致大鼠急性肺损伤有明显的保护作用，能对抗肺水肿的产生；对慢性炎症具有显著的抑制作用。

The situation with the machine physics function of every Slave and different configuration, the load that reuse random takes no account of function is balanced, it is very unscientific, the machine that can give machine function difference so brings needless high load, bring the risk of delay machine even, at the same time high-powered database server also cannot develop its physics property adequately.

每个Slave的机器物理性能和配置不一样的情况，再使用随机的不考虑性能的负载均衡，是非常不科学的，这样一来会给机器性能差的机器带来不必要的高负载，甚至带来宕机的危险，同时高性能的数据库服务器也不能充分发挥其物理性能。

The application problems mainly focus on how to solve triangle, acute triangle function, equation, inequation, function and its image, the three-dimensional image of a solid; while such knowledge as, plane geometry, solid geometry, operation of number and equation, trigonometric function equation, permutation and combination, ordered series of numbers sum, probability has no application problems.

4高中物理学习中存在运用困难的数学知识主要有函数及其图像、解三角形、锐角三角函数、方程、不等式、求函数极值、几何体的三视图等，然而，平面几何、立体几何知识、数与式的运算、三角函数公式、排列组合、数列求和、概率等知识基本没有运用困难。

The Frechet derivative of the cost function is determined via the solution of an adjoint partial differential equation, and the boundary shape is then modified in a direction of descent. This process is repeated until an optimum solution is approached. The advantage is that the cost function variation is independent of the flow field variation, with the result that the gradient of cost function with respect to arbitrary number of design variables can be determined without the need for additional flow-field evaluations. So each design cycle requires the numerical solution of both the flow and the adjoint equations leading to a computational cost roughly equal to the cost of two flow solutions.

虽然他们的研究成果大多数都可以在公开性文献上看到，但是其中一些具体的细节问题的处理方法却没有透露，比如：伴随方程如何离散求解才能减小最终梯度计算中的误差，使得设计过程有效地进行；伴随方程与流动方程的边界条件是不同的，如何合理地处理伴随方程的边界条件，才能推动设计过程朝着设计目标而发展；在减阻问题中目标函数如何定义，求解梯度的具体数学公式如何推导，如何通过数值方法来实现它们等。

The role of the environment is very important.

At that time, the High Court of England and Wales Court of Queen's Bench president of William Murray, Lord Mansfield in June 22, 1772 ruling:"No matter then there is the inconvenience, but there must be a decision, I can not say that this case under the law in England are permitted or authorized; are so black should be released."

当时的英格兰及威尔士高等法院王座法庭院长William Murray， Lord Mansfield于1772年6月22日宣判：「无论有那麽不便，但总要有个决定，我不能说这件案在英格兰法律之下是准许或认可；所以黑人是应该被释放。
