再分

In order to improve ability of anti-jamming, nowadays output of many measure-control systems' sensor is three thready difference signal and differ voltage range. Commonly, this signal is transacted by complex circuit , then it is collected. In this way, hardware cost of system is increased and precision of system is reduced.

现在很多测控系统为了提高抗干扰的能力，传感器输出信号多为3线制的差分信号，而且电压范围也不同，通常采用的方法是把差分信号通过复杂电路进行处理后再进行数据采集，这样不仅增加了硬件成本，还使系统的精度降低。

This study has introduced the relationship matrix between Kano's two-dimensional quality elements and quality improvement modes and importance of quality elements by double confirmed. According to judgement on decrement dissatisfaction more than increment satisfaction, the 3×3 matrix is composed of Kano's two-dimensional quality elements and quality improvement modes, that have 9 sets compose,it is supplyed 1~9 score or weight dividedly.

本研究推导出Kano二维品质属性与品质改善模式之对应关系，并以Kano二维品质模式归类结果及品质改善模式图对品质属性之重要度做双重确认；再依消除不满意优先於增加满意实施之判断，对「二维品质归类-改善模式」组成之3×3矩阵，分别给予9种组合1~9分不等的配分或权重。

When operating current of the main circuit rises over the setting value ILC1 and ILC2,connection signal will be sent out after time duration tC1 and t C2 separatively.

若分断此路负载后，主电路运行电流低于 ILC2且持续时间tc2 后，控制器可再发出信号，指令接通已分断负荷，恢复该负载供电。

In addition, Health Xuan Xuan's sub-cooked and cooked again declared using special processing technology create more varieties of processing paper, the main sub-wax Xuan, Fanshan Xuan, Xuan-color, color, such as over a hundred species of Symplocos Sun.

此外还有生宣熟宣之分，熟宣是采用特种再加工技术形成更多花色品种的加工宣纸，主要分蜡宣、矾宣、色宣、色矾宣等百余种。

Theoretical analysis and numerical results show that a steady positive period-1 solution bifurcates from the semi-trivial periodic solution through a transcritical bifurcation.

数值模拟显示，随着控制参数的变化，正周期-1解通过倍周期分岔出正周期-2解，再通过一系列倍周期分岔通向混沌。

Is the two-page 4 of the same unlt jihuaye Edition, by pressing a whole 印张 business card printing and making the hinge-Club membership card, and then manually offline organization staff paginated.

不离是把两个同样的4页制不败套分版，按一个不零印弛制卡和会员卡制作折页，再脱机布局员工手工举动不分页。

Taekwondo training at two stages, the first phase of training for the color belt, and the belt is divided into nine levels, and beginners, will be subject to a period of training passed an examination before they can be promoted after, taekwondo 10th white belt, 9th, white-yellow belt, 8th yellow belt, 7 - yellow-green belt, 6th green blelt, 5th green-blue belt, 4th blue belt, 3rd blue-red belt, 2nd red belt, 1st red-black belt, students needs at least a year and a half after completion of the first phase of training to more stringent by the requirement to pass an examination for promotion to the second phase of Ho - Black Belt, Black Belt is divided into nine, a few paragraphs is embroidered in black at both ends, and the other for you, Black Belt to Black Belt for some to accept at least four to seven years hard training, but also need to be more than six taekwondo authorized official in charge of the test invigilator.

跆拳道训练分二个阶段，首阶段的为颜色带训练，而色带分为九个级别，而初学者，必须接受一段时间的培训经考试合格后方可晋升，跆拳道十级－白带，八级－黄带，七级－黄绿带，六级－绿带，五级－绿蓝带，四级－蓝带，三级－蓝红带，二级－红带，一级－红黑带，学员最少也需要一年半时间完成第一个阶段后再接受更严格训练经考试合格，方何晋升第二个阶段－黑带，黑带共分九段，段数是刺绣在黑带两端，而供议别，黑带一段至黑带四段要接受最少七年时间苦练，而且还需要得到跆拳道会授权六段以上的监考官负责监考。

In comparison with the pure standards and the retention indices RI(subscript s reported in the literature, a total of 302 volatile compounds were identified in Changyu XO brandy, including 30 alcohols, 35 aldehydes and ketones, 20 carboxylic acids, 104 esters, 24 substituted benzenes and derivatives, 14 phenolic derivatives, 14 acetals, 16 furan derivatives, 22 terpenic and norisoprenoidic derivatives and 23 others.
