Simulation investigation on fluid characteristics of the water hydraulic jet pipe servo valve （WHJPSV） is conducted through a commercial computational fluid dynamics （CFD） software package FLUENT. In particular, the factors to fluid characteristics of WHJPSV are addressed, which include diameter combination of jet pipe and receiver pipe, jet pipe nozzle clearance, angle between two jet receiver pipes and deflection angle of the jet pipe. It is concluded from the results that：（i） Structural parameters have great influences on fluid characteristics of WHJPSV, when d1 = d2.= 0.3.mm, α= 45 , b = 0.5 mm, and the simulation exhibits better fluid characteristics; （ii） The magnitude of the recovery pressure and flow velocity increase almost linearly with the deflection angle of jet pipe. The research work in this paper is important for determining and optimizing the structural parameters of the jet pipe and jet receiver. The relevant conclusions could be extended to the study of other water hydraulic servo control components.

Based on the samples collected mesoplankton net from the south part Of Taiwan Strait (2.. 2. --2.. 65N, 117. 50 -- 12.. 00E) in August 1997, 2.2.species of zooplankton and 11 groups of meroplankton were identified. In the survey waters, Copepoda was dominant in either species or individual numbers. The diversity (H' ) was 5. 11 and the ratio of diversity to evenness (J ) was 7. 10, showing that the diversity of zooplankton was exceedingly high in the survey waters. Three zooplankton communities were clearly divided by systematical cluster analysis, indicating that the biotopes of these zooplankton communities may serve as the evidence for the basic status of distribution of water masses during the investigation.

Experiment and theoretical results of a LDA pumped, Q -switched, self-frequency-doubled NYBA laser are reported. With 400mW pumping power and the Q-switching at 16kHz repetition rate, an average output power of 6mW at 0. 53.m was achieved. The pulse-width at 0. 53.m is 2.ns, and a peak output power at 0. 53.m of 2.W is obtained at the Q -switching repetition rate of 100Hz. The experimental results are in agreement with theoretical predictions.

利用动态子结构法和神经网络直接逆自适应控制研究一种柔性车载液压机械手的弹性动力学建模和振动主动控制方法。根据机械手各部件的实际边界约束条件,将机械手系统分解成由不同约束的连续梁构成的九个子结构。在建立各子结构的动力学控制方程后,借助边界条件经综合得到系统的动力学模型;在液压作动器的作用点设置边界坐标,极方便地得到系统的状态控制方程。通过神经网络学习该动力学模型的逆模型,从而产生液压作动器的电压控制信号,在控制过程中神经网络能够自适应的调整控制参数,使系统的输出达到最佳控制状态。系统仿真结果表明,神经网络直接逆自适应控制技术明显优于传统的PID控制算法,且该方法具有很强的鲁棒性和良好的减振效果。

Glycosylation is the most versatile and one of the most significant protein post-translational modifications. It is generally classified into three categories according to the amino acid to which the glycan is attached: N-glycosylation, O-glycosylation and C-glycosylation. Synthesis of N-glycoproteins occurs in the rough endoplasmic reticulum (rER), and all N-glycoproteins synthesized in rER have uniform glycan endings with mannose (Man) and glucose (Glc). A systematic strategy was developed to comprehensively profile N-glycoproteins in complex biological samples. The lectin Concanvalin A (ConA), which has a high affinity for glycans ending with Man, was used to extract the N-glycoproteins synthesized or located in the rER, and identified the N-glycoproteins and their glycosylation sites by LTQ-FT MS. The analysis was repeated three times at both the biological sample and mass spectrometry levels. In total, 3.3.glycosylation sites on 2.2.N-glycoproteins were identified in the mouse liver. Of these, 13. were known N-glycoproteins in the Swissprot database. The identified N-glycoproteins were classified according to their cell location by the Swissprot database and GO software. The identified N-glycoproteins in this study would serve as a good complement to the N-glycoprotein database for the mouse liver.
