查询词典 restriction

Classic rough set theory based on equivalence relation takes complete system as object of study , and divides the region into some non-intersect equivalence class; But, in the real life, because of the errors in data measuring, understanding of data, or the restriction in data collection , it can make the decision-making system incomplete, that is, value of attribution of some objects is unknown, which restrains development of the theory to practical direction.

经典粗糙集理论以完备系统为研究对象，以等价关系为基础，通过等价关系将论域划分为互不相交的等价类；然而，在现实生活中，由于数据测量的误差，对数据理解或获取的限制等原因，使得在知识获取时往往面临的是不完备系统，即可能存在部分对象的一些属性值未知的情况，这就极大地限制了粗糙集理论向实用化方向发展。

在单端输入的差动放大电路工作原理教学中，对共模反馈电阻R e的作用，往往采用等效变换法进行分析，如果不注意正确使用分析条件会得出错误的结论，本文从理论和实践上指出了利用这种分析方法分析单端输入差动放大电路的局限性，最后给出了正确的分析方法及结论。

Magflow meters have found application in the process control industries (chemical, food-and-beverage, pulp and paper, water treatment) because they have low measurement error (0.2% of reading attainable) over a broad range (typically 30:1) and they require no moving parts (unlike turbine meters or paddlewheel technology) or flow restriction (unlike differential pressure meters) to operate.

因其在一宽广范围（通常为30：1）内具有低的测量误差（可达到读数的0.2％）且其在工作时不需要使用运动部件（不同于汽轮计或桨轮技术）或流量限制，磁性流量计已在过程控制行业（化学、食品及饮料、纸浆及造纸、水处理行业）中得到应用。

Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。

However, by taking advantage of the steric restriction offered by the three ethoxyl groups on the heads of the C8TES molecules, as well as the difference of the chemical activities between the OTS and C8TES molecules, it was possible to construct both the homogeneously and phase-separated mixed C8TES/OTS SAMs by means of the stepwise method.

但是利用C8TES分子头部三个乙氧基所形成的空间位阻以及C8TES和OTS分子之间反应活性的差异，采用分步法可以制备出混合均匀的均相和相分离(Phase-separated)的C8TES／OTS混合自组装单分子膜。

In order to ensure the accuracy of the match. Firstly the disparity gradient restriction across the direction of epipolar lines is used, and then on the basis of exclusionism searched the corner information close to edge point to guide the matching with restricted corners-searched range. The final match results ensure that the matching pairs in two images are one-to-one correspondences.

为了保证匹配的准确性，首先引入极线方向上的视差梯度约束，然后在考察唯一性的基础上，通过搜索并考察边缘端点周围的角点信息来引导边缘的匹配，并且限定边缘端点的角点搜索范围，最终匹配结果保证了两幅图像中的匹配对是一对一的唯一对应。
