不连续的

Where no significant changes have been made to the system or process, and a quality review confirms that the system or process is consistently producing material meeting its specifications, there is normally no need for revalidation.

在系统或工艺无显著的变化的情况下，质量审核证实了系统或工艺可以连续地生产符合质量标准的物料，通常情况下，不需要再验证。

Especially in the benthic optical fiber communication system, semiconductor laser diode is required to work more than 25 years.

但是半导体激光器作为一种高功率密度并且具有极高量子效率的器件，微小的输入电流和温度的变化都将导致输出光功率的极大变化，即使在小功率下也不能在室温下连续工作。

In this note, various definitions of lower semicontinuous set- valued mapping are extended to topological spaces without any metric topological and are compared.

According to structural characteristics of floating slab tracks, a track segment element was taken between two adjacent fasteners. For each element, rails were regarded as Euler beams supported by discrete viscoelastic supports. The fasteners and rubber supports were replaced by a linear spring and damp. So the vibration model of the floating slab track was established. In constructing vibration model of a metro train, each car of the metro train with two suspensions was modeled as a multi-rigid body system, in which rigid bodies were connected with each other by a linear spring and damp. Combining the potential energy of vertical vibration of the track with that of the metro train, the total potential energy of vertical vibration of the train and track was obtained. And then, the matrix equation of vertical vibration of the system was established using the principle of total potential energy with stationary value in elastic system dynamics and the "set-in-right-position" rule for formulating system matrices. The vibration responses of the system can be obtained by solving the matrix equation with the direct time integration such as Wilson-θ method.

摘 要：针对浮置板式轨道结构特点，取相邻2个扣件之间的轨道为1个轨段单元，钢轨视为连续弹性点支承Euler梁，浮置板视为弹性薄板，扣件系统及橡胶支座均模拟为线性弹簧及粘滞阻尼器，建立浮置板式轨道振动模型；将城轨列车中的车辆均离散为多刚体系统，各刚体之间通过线性弹簧及粘滞阻尼器相连，建立列车振动模型；将浮置板式轨道及列车振动势能叠加，得到系统竖向振动总势能；基于弹性系统动力学总势能不变值原理及形成系统矩阵的"对号入座"法则，建立此系统竖向振动矩阵方程；采用Wilson-θ逐步积分法求解此矩阵方程，得出此系统竖向振动响应。

Peng himself was a specialist in what the Chinese called a "short attack," hammering away at enemy defenses with successive compact combat groups, usually not more than a company in size, until a breakthrough or puncture was achieved, a tactic not unlike that used by German storm troops in the last years of World War I.

彭德怀本人就是一个中国人称之为"短促攻击战术"的专家，这种战术通过连续、小股的作战部队，通常不超过一个连的规模，向敌军防线发起猛烈攻击，直至找到一个突破口或者是防线缺口，这种战术与一战后期德国突击部队所使用的战术完全不同。

If the initial time series is not stationary it may be that some function of the time series, e.g. taking the differences between successive values, is stationary.

如果初始的时间序列不是平稳的，那么它可以对时间序列使用一些方法，例如，感受连续稳定的数据的差异。

Because of the tetrode working in severe condition, such as high voltage over to 13.5kV, the whole system must be under control. This system acquires the corresponding electric parameter of the tetrode constantly during the process of measuring.

In general, you should: 1 weather strip the entire door jamb; 2 apply one continuous strip along each side; 3 make sure the stripping meets tightly at the corners; and 4 use a thickness that, when the door closes, the stripping tightly presses between the door and the door jamb without making the door too hard to close.

在一般情况下，你应该：1）天气地带的整个门门框； 2）适用于每一个侧面沿带钢连续3）确保在弯道符合剥离紧密，以及4）使用厚度，当门关闭时，之间的门和门框的剥离紧紧压而不太难的大门关闭。

Enzyme as a biological catalyst is very sensitive to the environment , physical, chemical and biological factors.In the other hand it is difficult to purify from the reaction products. What's more it can not make a continuous operation.All those astrict the reaction.Under this condition, enzyme immobilization was put forward and developed.

酶作为一种生物催化剂，对环境十分敏感，易受物理、化学和生物等因素的影响而失活，而且反应后混入产品，纯化困难，不能实现连续操作，这些难以克服的现象大大限制了酶促反应在工业中的应用，在这种条件下，固定化酶的概念和技术得以提出和发展。
