【導(dǎo)讀】力的靜力效應(yīng)是指彈性物體受力作用后產(chǎn)生相應(yīng)變形的物理現(xiàn)象。只需測出物體的加速度，就可間接測得力值。測力的特點(diǎn)是通過測量力傳感器中質(zhì)量塊的加速度而間接獲得力值。、加速度型或物性型。按其工作原理則可以分為：彈性式、電阻。應(yīng)變式、電感式、電容式、壓電式、壓磁式等?，F(xiàn)象，其原則上可簡化成圖所示的單自由度系統(tǒng)。)(tf為激振力，為系統(tǒng)的輸入；z振動(dòng)位移，為系統(tǒng)的輸出。是一種用于測量壓縮力的應(yīng)變片式測力頭的典型構(gòu)造。器的直流不平衡電橋的電路。橋臂接固定電阻。的變化，電橋處于不平衡狀態(tài)，此時(shí)。為了獲得較大的靈敏度，采用梁式結(jié)構(gòu)。機(jī)械力，從而引起其磁導(dǎo)率（或磁阻）發(fā)生變化，這種物理現(xiàn)象稱為“壓磁效應(yīng)”。件與電氣傳感器相結(jié)合構(gòu)成壓力變送器，以實(shí)現(xiàn)遠(yuǎn)距離傳輸。圖給出了一些用于轉(zhuǎn)矩傳感器的扭矩軸彈性元件。

　　

【正文】 eremony. In this way, they didn39。t really dare to adhere to the principle. No rade, constantly put on reworking an emergency meeting to Comrade Zhen to speak louder, management tube too strict. Remember in Dongguan Street, 400 meters long cement concrete surface layer, because of various reasons, the smoothness of the poor in the bottom cavity, covering film traces and car imprinting quality problems, * * * inquiries, immediately rushed to the scene to understand and verify the situation, the convening of the management office, the construction units, supervision units, construction units, construction units construction time is tight, the economic loss and other reasons to intercede ******** unmoved. He said, now a popular word, to the discipline and rules quite in front, there are no rules Radius, you construction team not accordance with the technical specifications, quality problems, it must be to carry out rectification. Engineering quality responsibility be weightier than Mount Tai, if we manage to this matter Pavement quality quantity are placed the matter, we this time to learn two regulations have what use? Still what is the Communist Party? Finally, in his insisted, the road after rework, to solve these problems. In the construction of the new rades and the project all the colleagues efforts, after four months of fighting, the project the main project was finally pleted and passed inspection. Thousands of miles of ice, thousands of miles Piao, this is a splendid and romantic scene. But snow for the highway, it is a disaster, a serious threat to the traffic safety. This year, a month, a century of cold wave swept from North to south, and the snow blowing to Guangdong, but also to bear the blow To * * * * the highway. In January on the evening of 23, Lianping county city temperatures dropped to minus 2 degrees, a wide range of sudden rain sleet, before and after the provincial S341 line in Jiulianshan Mountain tunnel sections of the road appeared in the snow, lead to the passing vehicles skid, traffic is blocked. In the face of the sudden natural disasters, city and county highway department immediately launched the emergency plan for disaster prevention. As the front line of the main force, Lianping Highway Bureau of all Party members and cadres to remember the Party member responsibility, braving the biting cold wind, the first time rushed to the scene, on the icy pavement of salt disposal. Because the temperature is too low, just melt water immediately freezes, addition to the ice work to increase the difficulty. To ensure In addition to the re anization of the depths of the traffic safety, road people braved the icy put reflective cones and warning signs, endure cold at minus 2,3 of Jiulianshan patrols until one in the morning. Just before dawn, Lianping Highway Bureau personnel on the icy road salt ice melting processing until ten o39。clock, ice melting ice success, the road gradually returned to normal traffic. In the cold winter night, which people do not miss the warm bed, which people do not miss the warm home. However, our highway on the road to the owners of the masses can go home early, the night fighting to secure the avoidance of the road safety and smoothness, fulfill their responsibility. Xi General Secretary Every Party member cadre cautioned against said: blacksmith needs self hard . two regulations , is our own hard standard test, more exercise every party members and cadres of the fire. We should continue to strengthen the party two regulations, conscientiously in practical work, practical play road, the road for the development of the cause of Heyuan and struggle. In the industry domain report the situation of road traffic in recent years, in the province highway departments of the concern and support, our bureau management department based on the job, loyalty duty, best service, to further promote the highway management standardization, legal, scientific and information technology to improve the management level and service quality. This will be my last work is as follows: first, around the center, go all out to greet the seizure in 2020, meet national examination is my bureau work. As the highway management department, we focus on the work of the center to strengthen road renovation and management as the focal point, further optimize the service environment, improve service levels. Inspection, the inspection group and the Ministry of transport, the Bureau under the leadership of the ministries and agencies highly evaluated and fully affirmed. (a) increase road area remediation efforts. The programme of work, strengthen the anization and leadership. The timely development of the city of *** mon trunk highway area environment remediation plan , along the road signs and markings, traffic safety facilities, on both sides of the green, advertising signs, control area illegal construction and implementation of remediation tasks to the relevant departments, clear work time of the node to ensure rectification work timely. Set up road area special rectification work leading group, implement a bureau, the Bureau of the county (District), the project road site domain environment prehensive improvement Mechanism. To ensure that the work carried out smoothly, the bureau also anized the city road managers participated in the regulation of road region and the relevant laws and regulations of the special training. 2. Active butt joint is reported, actively strive for the support of. Local Party mittee and government support is the job As a magic weapon, I am one of the Bureau of the principal leaders repeatedly attack inspection remediation and road area to the principal leaders of the municipal report. * * *, the Secretary of municipal Party mittee, mayor * *, * * *, vice m
