In recent years,the protection of traditional villages has been continuously promoted.Tra-ditional villages are not only carriers that inherit and develop rural culture but also important areas for implementing rural revitalization strategies.How to improve the protection of villages is a problem urgently needed to be solved in the landscape architecture industry.Based on this,this article takes Anyi ancient village in Jiangxi as an example,using methods such as field investigation and ques-tionnaire interviews from the perspective of resource feature exploration,to sort out the basic over-view of Anyi ancient village,analyze the resource characteristics and protection status of Anyi ancient village,and propose four strategies for protecting the resource features of Anyi ancient vil-lage,namely:preserving the traditional pattern and style and retaining the unique features of the ancient village;inheriting the traditional architectural features and improving the village environ-ment;revitalizing traditional folk culture and continuing the cultural heritage of the ancient village;developing special rural tourism and assisting the revitalization of the ancient village.
With the development of society and the acceleration of urbanization,urban road safety has become a focal point of attention.In this study,Ground Penetrating Radar(GPR)was utilized as an efficient geophysical method to investigate the detection of road quality and defects on a large scale in urban areas.A numerical simulation software,gprMax,based on the Finite-Difference Time-Domain(FDTD)method,was employed to simulate the electromagnetic wave propagation and perform geophysical forward modeling of common road anomalies and defects in urban environments.By analyzing the generated B-scan radar profiles and visualizing the geometric models,the radar re-sponse characteristics of different anomalies and defects were studied and analyzed,providing guid-ance for the data analysis and interpretation of practical road GPR surveys.Finally,by integrating actual data collected from road GPR surveys in Nanchang city,a road quality assessment was con-ducted,and potential defect types were identified.The results indicated that this method effectively served the detection of urban road quality and defects using GPR,providing an efficient approach for improving urban road quality and defect investigations.This research holds significant importance in addressing the increasing challenges of urban road safety.

With the gradual promotion of the construction of electric Internet of Things,the types of intelligent terminals deployed on transmission lines are gradually increasing,and the operation relia-bility requirements of intelligent terminals are increasing.In order to solve the problems of multiple operation faults and poor reliability of intelligent transmission terminal,an operation control strategy of intelligent transmission terminal based on hierarchical analysis is proposed.This method builds a two-layer model through hierarchical analysis.The lower layer model solves the control requirement of the terminal timing task,and the upper layer model combines the micro-meteorological factors to optimize the terminal control,so as to improve the operational reliability of the terminal.The pro-posed method is verified in the simulation platform,and the terminal failure rate is 3.1%,which is lower than that of the cloud model method.Firstly,the method adopts hierarchical analysis to ana-lyze the indicators affecting the reliability and failure of intelligent transmission terminals.Secondly,the entropy weight method is used to adjust the weight of the indicators,and the operation status of the transmission intelligent terminal is evaluated.Finally,combined with weather and other factors,intelligent power transmission terminals were established to carry out operation control strategy,to a-chieve optimal control of intelligent power transmission terminals,and the operation failure rate of intelligent power transmission terminals was reduced by 44.3%.The method proposed in this paper can effectively improve the operational control level of status assessment of intelligent terminal in running transmission and reduce the failure rate.
The valve is a very important core equipment in the thermal power plant,valve stem fail-ure will make the valve can not work properly,which may lead to abnormal unit shutdown and cause safety accidents.By using finite element simulation and physical and chemical testing methods,fail-ure analysis and improvement measures were proposed for the fracture of 410 stainless steel stem for the main steam valve of the thermal power unit.The results of the analysis showed that the failure was caused by improper setting of the electric actuator of the gate valve and stress concentration at the retraction groove of the stem.By improving the stem structure and adding nitriding treatment to the stem,the stress distribution of the stem can be improved and the surface hardness and wear re-sistance can be increased.

In this study,seven emulsifier-based nutritional shakes with balanced and complete mac-ronutrients achieved the same structural features and matched macronutrients through different sources of protein,oil,effective carbohydrates or fiber nutrient levels.Using a randomized crossover trial(n =15).The results showed that compared with sodium caseinate,soybean protein could re-duce the peak blood sugar(P =0.000 3).Medium-chain triglycerides(MCTs)lowered blood glucose levels at 30 or 45 minutes compared with long-chain triglycerides(LCTs)(P＜0.000 1 or =0.000 8).Maltodextrin reduced peak blood glucose levels compared with corn syrup(P =0.005 8).Maltodextrin + whey protein decreased blood glucose levels at 45 minutes compared with corn syrup + sodium caseinate(P＜0.000 1).MCT+whey protein+syrup+fructooligosaccharide(FOS)(P＜0.000 1),LCT+whey protein+maltodextrin+FOS(P＜0.000 1),LCT+whey protein+syrup+oat fi-ber(P =0.002 7)and LCT+sodium caseinate+syrup+FOS suppressed food intake compared to LCT+sodium caseinate+syrup+FOS.These comparative data suggest that postprandial blood glucose and food intake following consumption of nutritional shakes can be manipulated by altering the source of one or both macronutrients.

It is of great practical value to determine the distance and speed of motion accurately.In this paper,the GNSS observation value of smart phone is used for the standard point positioning(SPP).We use the differencing and the moving average method to correct the smart phone's stand-ard point positioning coordinates,and then use the modified coordinates to calculate the distance and speed of motion.The results showed that no matter whether the high-precision geodetic GNSS re-ceiver OR smartphone GNSS receiver was used as the base station,as long as the smart phone was used as the rover,smart phone positioning accuracy could not be significantly improved by position difference correction.It was related to the error composition of SPP(including tropospheric and ion-osphere model correction)on the smart phone,that was,the main part of the error was the non-public error between the rover and the base station,which could not be eliminated by differencing.The distance and velocity derived from the coordinate time series filtered by moving average method were accurate:comparing with the result from roller measurements,the distance errors were less than 15 m(total distance larger than 4 000 m),and the velocity errors were less than 0.65 m/min(the speed is 80～150 m/min),the accuracy was equivalent to the data accuracy of commercial sports watches.
