查询词典 metric ton

In this way, we can get the optimum parameters which are ip = 100mA/cm2, ton/toff = 0.1s/0.5s, and loading capacity 6C/cm2. This result is suitable for both the hydrogen adsorption and the methanol oxidation.

发现脉冲参数控制在ip=100mA/cm2、ton/toff=0.1s/0.5s、通电量6C/cm2时，不论是氢的脱附或甲醇的氧化，该电极触媒活性表现均最佳。

In this thesis, the heterojunction with intrinsic hydrogenated amorphous silicon thin layer ( heterojunction with intrinsic thin layer: HIT) solar cells are investigated. The solar cell structure of p/i/n are fabricated. The substrate is a typical 4-inch n-type wafer with (100) crystal orientation, 1~10 ohm-cm and about 525 μm thickness. The p and i a-Si:H layers are deposited by a 13.56 MHz plasma enhanced chemical vapor deposition. The i a-Si:H layers are especially deposited by pulse-wave modulation plasma technique with fixed plasma turn-off time toff = 10 ms and changed plasma turn-on time ton= 10 to 40 ms to selectively control the different silicon to hydrogen bonding configurations. The effect of various Si:H bonds on the performance of HIT solar cells are explored.

中文摘要本论文针对异质接面薄本质层(heterojunction with intrinsic thin layer： HIT)太阳电池进行研究，采用一般典型四英吋晶向为(100，厚度约为525 μm，电阻率约为 1~10 ohm-cmn型矽晶圆为基板，制作p/i/n太阳电池，p及i层薄膜以13.56 MHz电浆加强化学气相沈积，i层并采用脉波调变电浆技术，在固定电浆关闭时间toff = 10 ms及改变电浆开启时间由ton = 10 ms 至40 ms条件下制作具有不同矽氢键结微结构的氢化非晶矽薄膜以探讨不同矽氢键结对太阳电池性能的影响。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
