用负压铸渗工艺制备了WC/HT300基表面复合材料,研究了WC体积分数和冲蚀磨损浆料中的颗粒粒度对复合材料的抗冲蚀磨损性能的影响。对于同一种WC颗粒体积分数的复合材料,当浆料中的石英砂粒度大时,复合材料的体积磨损率较大,抗冲蚀磨损性能降低。WC体积分数为27%和36%的表面复合材料具有比其他WC体积分数复合材料优越的耐磨损性能;在磨料粒度为40～70目的工况下,WC体积分数为36%的复合材料,具有比体积分数为27%的复合材料优越的耐磨性能;但在磨料粒度增大到20～40目时,WC体积分数为27%的复合材料,具有比WC体积分数为36%的复合材料优越的耐磨损性能。

光谱吸收曲线-线性拟合斜率-分光光度法(SAC-LFS-S)用于检测地表水中甲醛尚存准确度不足问题,通过筛选合适的参比波长段,使SAC-LFS-S法准确度进一步提高。以试剂空白和浊度梯度地表水样品的检测结果及方法检出限为主要筛选对象,得到425~435、420~435、420~440、415~440、415~445、410~445、415~450、410~450、455~495、410~455、405~455、450~500 nm等共12个合适的测定波长段;再选择试剂空白结果较低、批间重复性较好的450~500 nm测定波长段,筛选参比波长段(455~465、480~495、450~490 nm共3个)。结果表明:优化后SAC-LFS-S法线性范围为0. 100~3. 00 mg/L,方法检出限为0. 025~0. 033 mg/L;优化前、后方法测得部分地表水样品结果分别为有检出和未检出,回收率为73. 4%~108. 8%,后者与无亮黄色化合物产生的实验现象更吻合。经参比波长段校正的SAC-LFS-S法具有更高的准确度,非常适用于地表水中甲醛的直接测定。

交叉口是城市路网的核心和枢纽,合理优化交叉口的信号控制可以极大地提高城市交通体系的运行效率,而将实时交通信息作为输入并动态调整交通信号灯的相位时间成为了当前研究的重要方向。文中提出了一种基于D3qN(Double Deep q-Learning Network with Dueling Architecture)深度强化学习模型的交通信号控制方法,其利用深度学习网络,结合交通信号控制机构成了一个用于调整交叉口信号控制策略的智能体,然后采用DTSE(离散交通状态编码)方法将交叉口的交通状态转换为由车辆的位置和速度信息所组成的二维矩阵,通过深度学习对交通状态特征进行高层抽象表征,从而实现对交通状态的精确感知。在此基础上,通过强化学习来实现自适应交通信号控制策略。最后,利用交通微型仿真器SUMO进行仿真实验,以定时控制和感应控制方法作为对照实验,结果表明文中提出的方法得到了更好的控制效果,因此是可行且有效的。

为提高本地负载的供电安全,分布式发电(DG)并网逆变器需要工作在并网和离网两种状态,且能无缝切换。提出一种综合的DG无缝控制策略。针对非计划孤岛DG从并网切换离网状态存在失控区域,易引起本地负载电压和频率越限问题,提出采用P-σ、q-v解耦的非线性控制,实现失控期间的直接电压限幅;提出结合锁频环和去除积分前向通道的锁相环,在不影响锁相环动态特性基础上,实现失控区域的频率限幅。另外,在该控制结构基础上提出一种虚拟并网的预同步方法,避免并网开关闭合时内外环失配,改善并网过渡过程。基于RT-LAB的硬件在环仿真验证了该策略的有效性。

OBJECTIVE: To evaluate the indicators of an animal model of gouty arthritis(GA) with dampness heat accumulation and the intervention effect of Tongfeng qingxiao formula(痛风清消方, TFqxF). METHODS: Seventy-two healthy adult Sprague-Dawley male rats were selected and randomly divided into a normal group, model group, low-dose group, mediumdose group, high-dose group, and diclofenac group using a random number table method, with 12 rats in each group. After group intervention, the general condition of the rats in each group was monitored and recorded, and the swelling index was measured. After separating the serum, the changes in glutamic pyruvic transaminase (ALT), glutamic oxaloacetic transaminase(AST), carbamide(UREA), creatinine(CREA), triglyceride(TG), total serum cholesterol(TC), low density lipoprotein cholesterol(LDL-C), and high density lipoprotein cholesterol(HDL-C) in the serum of the rats in each group were measured using an automatic biochemical analyzer. The levels of motilin(MTL), gastrin(GAS), endothelin(ET), calcitonin gene-related peptide(CGRP), heat shock protein 70(HSP70), interleukin(IL)-1β, and nuclear factor kappa-B(NF-κB) in the serum of the rats in each group were evaluated using enzyme-linked immunosorbent assay(ELISA) kits. Kidney tissues were used to evaluate the protein and m RNA expression of aquaporin(AqP) 1 and AqP2. Colon tissue was used to evaluate the protein and m RNA expression of AqP3 and AqP4 by Western blotting(WB) assay and real-time quantitative polymerase chain reaction(RT-q PCR). The levels of ALT, AST, UREA, and CREA were used to evaluate the liver and kidney function of rats. The levels of MTL and GAS were used to evaluate the gastrointestinal function of rats. The levels of TG, TC, LDL-C, HDL-C, AqP1, AqP2, AqP3, and AqP4 were used to evaluate the "dampness" syndrome performance in rats. The levels of ET, CGRP, and HSP70 were used to evaluate the "heat" syndrome performance in rats. The levels of IL-1β and NF-κB were used to e

The central oscillator of circadian clock in cyanobacterium,Synechococcus elongatus PCC 7942,is composed of kai A,kai B,kai C proteins. Many researches confirmed that this self-sustained intracellular circadian clock,so-called Kai clock,have played a pivotal role in the generation and calibration of the time clue for the circadian rhythm in cyanobacterial metabolism. Some proteins,such as Sas A、Lab A、Cik A、Rap A,are considered to be the key switches that have operated the output pathways of Kai clock. Peroxiredoxins(Prxs) in short,are families of thiol-specific antioxidant protein,which have be convinced to exert an important function in the whole antioxidant defense system of cyanobacteria,the rhythmic changes redox state of 2Cys-Prx are proved as a conserved non-transcriptional rhythmic marker. To test the relationship between the Kai clock and the PRx-SO rhythmic marker,the expression patterns of clock genes were detected of by q PCR method in Wild-type(WT) and prx-2cys gene knockout(Δprx-2cys) trains under different light intensity. The results demonstrated that under the natural light condition(100μEms),the rhythmic expression phenotype of the central clock genes were not affected by whether the prx-2cys gene were knocked out in *** PCC 7942 cells,while the expression patterns of the genes operating the output pathway were slightly affected. Interestingly,under a high light stressed condition(400μEms),the expression patterns of the output pathway genes were severely affected both in WT and Δprx-2cys strains. The circadian rhythmic expression pattern of the central clock genes nearly disappeared in WT strains,while more robust rhythmic expression profiles of sas A 、 lab A 、 cik A 、 rap A were restored inΔprx-2cys cells by an unknown method.
