According to the relevant building codes, when the length of the hanger rod was greater than 1.5m, the anti-support should be set up, but the specifications of the anti-support were not clearly defined in the construction regulations. Usually, according to the calculation of the design institute, it can be connected to the main joist by using the steel bars, angle iron, square steel, etc. The distance between the anti-supports should not be greater than 3600mm, and the distance from the wall should not be greater than 1800mm. They should be arranged adjacent to each other. In terms of anti-support performance, in actual work, such as the ceiling of the clean workshop of an industrial plant (using a large clean board and the middle ceiling space as the maintenance floor, the relative height is relatively high, and there is no need to add anti-support in the absence of special requirements). There were three common ways to counter support: Main Dragon Bone Knitting (It is applicable when the length of the boom is more than 1.5m and less than 3m. Punch holes at the bottom edge of the horizontal brace of the main joist of the C60 every two main joists. The M8 full-toothed boom will pass through. After the position is determined, the upper and lower nuts will be fixed. The inclined brace of the main joist of the C60 will be set opposite to each other every two times the main joist. When the length of the boom is more than 1.5m and less than 2m, the C50 main joist can be used instead.)(It is applicable when the length of the hanger rod is more than 1.5m and less than 3m. The inclined steel bars shall be set at intervals of two times the distance between the main keels. The 8 horizontal steel bars, inclined steel bars, and their joints with the M8 full-toothed hanger rod must be anti-rust treated. The 8 steel bars can be replaced by the M8 full-toothed hanger rod, but the joints must be anti-rust treated.), inverted triangle method (it is applicable when the length of the hanger rod is more than 1.5m and less than 2m. The installation distance shall be within 2m. It shall be distributed in the shape of a plum blossom around a certain center and shall not be set on the same straight line.)

Brothers in the countryside fight

Brothers in the countryside might fall out and fight for many reasons. For example, in terms of resource allocation, some brothers might fight because of the uneven distribution of land and other assets left behind by the elderly in some families. For example, in a certain rural family, after the death of two old people, they left behind an old house and four and a half acres of land. Originally, they had agreed to give the extra half an acre of land to the fourth brother who had taken care of the old people for many years. However, the eldest brother's wife did not agree and wanted that piece of land to compensate the eldest brother for not receiving the benefits of the old man when he was teaching outside all year round. The fourth brother's wife felt very wronged because when she took care of the old people, others were unwilling. Now, they were fighting for the land. Under such circumstances, conflicts would arise between the brothers. In serious cases, it might lead to fights and other conflicts. There might also be conflicts over the responsibility of taking care of the elderly. In some families, the elderly were ill and needed to be taken care of. The brothers would have disagreements because of their own difficulties or economic interests. For example, some brothers felt that they were too busy to take care of the elderly and proposed to exchange money for a nanny. Some brothers disagreed because they were not rich. During the negotiation process, the contradictions escalated, which might also lead to brothers falling out and even fighting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

DSLR Testing

The following is some information about the DSLR test: - Germany had tested 35 single-lens reflex and mirrorless cameras. The 188 digital cameras tested were divided into six categories (37 compact cameras, 35 single-lens reflex cameras, 76 cameras with changeable lenses, 22 sports cameras, 10 drones with cameras, and 18 webcameras). Three single-lens reflex cameras were "excellent" and from the same brand. 24 single-lens reflex cameras were rated "good", seven "medium", and one "pass". - Compared to mirrorless cameras, DSLR cameras had their own characteristics. From a structural point of view, the mirror structure of the single-lens reflex camera was one of its cores. Light was projected through the lens onto the mirror, and the mirror reflected the light to the pentaprism and finally to the viewfinder. This structure was relatively complicated. In terms of focusing performance, early single-lens reflex cameras led the way in focusing speed and accuracy with the help of phase detection autofocus systems. However, in recent years, autofocus technology for mirrorless cameras had developed rapidly. With full-pel dual-core focus, eye-tracking focus, and other functions, it had surpassed single-lens reflex cameras. Due to the limitation of optical mirrors, the focus system of single-lens reflex cameras could only cover a part of the frame. In terms of video performance, single-lens reflex cameras used to dominate the field of video capture, but mirrorless cameras could achieve real-time focus and continuous framing without the need for a mirror. With the popularity of 4K and 8K video recording functions, mirrorless cameras had obvious advantages in video capture. In terms of the portable aspect, the mirror system of the single-lens reflex camera increased the size and weight, while the body design of the mirrorless camera was more compact and light. As the performance of the mirrorless camera reached or even exceeded the level of the single-lens reflex camera, without sacrificing the quality of the image, the mirrorless camera was more suitable for long-term outdoor shooting. In terms of intelligence, the mirrorless camera was equipped with more advanced electronic systems and software functions, such as Wi-Fi, Bluetooth, touch screen, etc., which supported more intuitive touch operation and could display real-time changes in parameters such as exposure and white balance. The DSLR camera was scarce or had a poor experience in these functions. - In terms of the characteristics of the single-lens reflex camera, it had an optical viewfinder, which could provide the most realistic image. It could work perfectly even in dim light. Some old-fashioned electronic viewfinders with low refresh rates would display flashing previews. The optical viewfinder had an advantage when shooting fast-moving objects. If the optical viewfinder was mainly used for shooting, it could take 1000 or more photos on a single charge with low energy consumption. When changing lenses, the mirrors would fold up to protect the sensors from dust or sand. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
