测定各种进口流态、闸室流态、下游水流衔接流态、流速分布以及下游回流和尾水波动状况。

Mazda's global design chief Lauren Van den Acker has previously mentioned that the next MX-5 will be a major leap in terms of styling and dynamics over the current model, and its chief developer Takao Kijima has also stated that the new model will be smaller and at least 10% lighter than the current car, which means a kerb weight around the 1,000kg mark.

马自达全球设计首席劳伦范登贝安克尔曾提到，在未来的MX - 5将是一个重大的飞跃，造型方面和动力比目前的模型，其主要开发隆夫杵岛还指出，新的模式将更小，至少有10 ％重量比目前的汽车，这意味着在路边重量一〇〇〇公斤大关。

The design cross sectional area of shunt is calculated by the product of carrying rated current ratio and Bi-2223/AgAu matrix and shunt resistivity ratio. When quenching happens, shunt carries more current to void burn out or overheat of superconductor. Shunt which provides an enough heat sink can restrain the temperature rising of HTS section too fast.

分流器横截面积确定基于分流器与Bi-2223基体AgAu的电阻率对失超后电流分配比，这样保证超导体转人电阻态后分流器分流大部分电流，同时由于分流器具有很好热沉作用，抑制超导体温度迅速上升，从而避免超导材料烧毁或过热。

深水异地沉积主要包括重力流沉积和深水牵引流沉积两大类；深水原地沉积主要包括深水泥页岩沉积。

This control system includes main control model, current detection, position sensing, fault detection and protection, serial interface. Anisomerous bridge topology structure is adopted to design the power converters and driver circuit. Double closed loop based on velocity and current is adopted to control AC-motor.

其控制电路主要包括主控模块、电流检测模块、位置传感器模块、串口电路、故障检测和保护电路等；采用不对称桥式扑结构设计了功率变换器及其驱动电路模块；采用速度和电流双闭环的形式，完成对交流电机的控制。

The results showed that the current flowing between working electrode and auxiliary electrode were limited in a certain area by the apertural current limit sensor, and the noise disturbance and the IR drop caused by soil resistance were well eliminated by wavelet transform and Levenberg-Marquardt algorithm respectively.

结果表明，小孔限流型传感器具有明显的限流效果，小波变换和Levenberg-Marquardt算法能够有效消除充电曲线数据中的噪声干扰和土壤电阻影响。

Our current labor dispute settlement system can not be suitable to the need of current settlement of labor dispute system because its period of settling the labor dispute is long in actual situation, giving heavy burden to litigant; the function of labor dispute mediation committee is limited, arbitrational system is not complete, tripartite principle exists in name only, there is no relevant evidence system, arbitration and litigation are difficult to link up and so on.

我国目前的劳动争议处理机制不适应现实劳动争议处理需求，造成实践中劳动争议处理周期过长，当事人负担重；在劳动争议的具体解决机制中，劳动争议调解委员会的作用有限，仲裁制度尚未形成完善的体系，三方性原则虚置，举证责任分配不明，仲裁与诉讼难以有效衔接等。

Said invented method for and device adopt MCU or logic or logic chip detecting said ringing current signal, backboard ringing current signal and mutual sent signal, and sequential control sequential control, avoiding switch device hard switching and arcking, raising switch device and backboard reliability.

本发明方法及装置通过采用MCU或逻辑芯片检测本板铃流信号，背板铃流信号和互送信号，并采用时序控制，避免了在铃流开机和切换时的开关器件硬切换，以及铃流的在开关电路切换时的拉弧，提高了开关器件的可靠性；而且把开关电路从通讯设备插框背板转移到单板上来，提高了背板的可靠性，降低了后续的维护和检修困难。
