The composition and proportion of the bleachersThe main components of the bleachers were calcium chopstick and calcium chloride.Among them, calcium chopstick was the active component and had strong oxidisation. The ratio of the bleaches could be determined according to different uses. For example, when used to deal with moldy floors, you can mix rinsing water and water in a ratio of 1:3. For household sterilization, you can mix 10 milliliters of rinsing water with 990 milliliters of clear water and dilute it in a ratio of 1:99. For cleaning and disinfecting excrement or secretions, you can mix 10 milliliters of rinsing water with 490 milliliters of clear water and dilute it in a ratio of 1:49. Different cleaning needs may require different proportions, so the proportion of the use of whiteness needs to be determined according to the specific situation.
Mix proportion of the castableThe mix ratio of the castables varied due to the different materials used and their uses.
For an important type of unshaped fire-resistant material such as the CA - 50 cement castable, if the grade-2 kiln was used to prepare the fire-resistant material and powder, the total amount of CA - 50 cement and fire-resistant material would be 27% - 30%, the amount of fire-resistant material would be 70% - 73%, and the amount of CA - 50 cement would be 10% - 20%. When used in medium-high temperature parts, the amount of cement should be reduced and the amount of fire-resistant powder should be increased. The grade of the fire-resistant powder should be the same as or one grade higher than that of the fire-resistant gravel. The fire-resistant gravel can be reasonably selected according to the service temperature of the kiln. The grain grading is usually two-grade grading or unified material.(The ratio of fine gravel to the whole gravel) is generally controlled at 0.45 - 0.55. The amount of water can be expressed by mass percentage, kilogram per cubic meter or water-cement ratio (the ratio of water to cement and powder). The principle is to reduce the amount of water as much as possible under the condition of ensuring the easiness of the castable mixture. The common mixing ratio should be determined by the test during production or construction according to the variety of raw materials and the use conditions. At the same time, it should be added as much as possible to improve the construction and fire resistance performance.
Castables made from aluminum clay:
- Binder: No. 625 and above aluminum cement, with a mixture ratio of 15% - 20%.
- "Agglomerate: made of Grade 2 and Grade 3 aluminum chamotte or Grade 1 and Grade 2 clay chamotte, waste high-aluminum bricks and waste fire-resistant clay bricks. The grain size of fine agglomerate is less than 5mm, and the mixing ratio is 30% - 40%. The grain size of coarse agglomerate is 5 - 15mm, and the mixing ratio is 30% - 40%.
- Powder (Admixture): The same as the gravel, not less than 70% of the grain size is less than 0.088mm, and the mixing ratio is 0 - 15%.
Phosphate-based casting material:
- Binder: 42.5 or higher grade cement, with a mixture ratio of 15% - 20%.
- "Agglomerate: made of Class I and Class II clay grog or waste firebricks. The grain size of the fine gravel is less than 5mm, and the mixing ratio is 35% - 40%. The grain size of the coarse gravel is 5 - 15mm, and the mixing ratio is 30% - 40%.
- Powder material: the same as the gravel, not less than 70% of the grain size is less than 0.088mm, and the mixing ratio is less than 15%.
In general, the formula of the fire-resistant casting material included fire-resistant material, fire-resistant binding agent, fire-resistant filling material, and other materials. The fire-resistant material is the main component, such as high-aluminum material and silica material, etc. The fire-resistant binding agent is composed of phosphorous acid, silica acid, aluminum acid, etc. The fire-resistant filling material is used to fill the gap of the material, such as mica, expanded pearlite, etc. The addition agent is used to improve the performance of the castable, such as enhancing the fire-resistant performance and increasing the density. Its formula needs to be adjusted and optimized according to the specific use environment and requirements.

National examination registration ratio and recruitment ratioThe registration ratio was the ratio of the number of applicants to the number of people hired. It reflected the intensity of the competition for the national examination positions. For example, as of 16:00 on October 22, the highest competition ratio for the 2025 national examination was 9780:1, and as of 16:00 on October 24, the highest competition ratio for the position was 6558:1.
The recruitment ratio was the ratio of the number of people hired to the number of applicants, and it was the countdown of the registration ratio. For example, the national examination in 2025 was planned to recruit 39,700 people. As of 16:00 on October 22, a total of 2035585 people had applied for the examination. The recruitment ratio was about 1:51.27 (39,700: 2035585). This ratio reflected the recruitment of national civil servants among the applicants.

Life and speed should be in proportionAccording to the reference materials, there was a point of view that the limit of human running speed was determined by muscle strength, movement speed, and the most suitable ratio of pace to height. Although the exact meaning of the ratio of life and speed was not explicitly mentioned, it could be speculated that in all aspects of life activities, speed should be maintained in an appropriate ratio to related factors. For example, the speed of human running was affected by the ratio of body functions. In social life, the ratio of life to speed could be understood as a balance between the speed of human development, the rhythm of life, and the quality and meaning of life. For example, in the current rapid development of society, people might need to think about how to ensure the health and poetry of life while pursuing speed (such as speed of development, work rhythm, etc.). Among the attributes of the military, speed, as a type of military attribute, together with health, attack, and so on, constituted the combat power of a single soldier. This also reflected the proportional relationship between speed and other factors in a special "life-related" situation like military confrontation.
The proportion of subjects in the examination of teachersTaking the teacher-compilation ratio of Shandong Province in 2022 as an example, it includes 15 subjects such as Chinese, mathematics, English, physics, chemistry, biology, geography, history, politics, music, sports, fine arts, infants, psychology, information technology, etc. Among them, the art discipline has the highest competition ratio in Weifang, Dongying and other places. Weifang plans to recruit 27 people and register 2818 people, with a competition ratio of 1:105. Dongying is 1:56; In Zaozhuang, Linyi, Binzhou and other cities, the competition for art was also the highest. The overall competition ratio of the provinces and cities was relatively low, mainly in politics, history, geography, and other secondary subjects. The competition ratio of the main subjects such as Chinese, mathematics, and English was relatively high, and the competition level of other subjects was in the middle.

Golden ratioIn photography, the golden ratio was an important concept of composition. In terms of mathematical definition, a line segment was divided into two parts. The ratio of the longer line segment to the full length was equal to the ratio of the short line segment to the long line segment. The ratio was 0.618. This point was called the Golden Section Point. Although it was not as accurate in photography composition, there were many applications related to the golden ratio.
A common application was the golden ratio, such as 2:3, 3:5, 5:8 and other approximate proportions were often used in photographic composition, also known as the golden ratio. There was also the Nine Palace Diagram, which drew two horizontal and vertical lines (virtual) on the screen, dividing the screen into nine equal squares. The four points where the horizontal and vertical lines intersected were the golden ratio points. In theory, they were close to 1/3 and 2/3 (0.666) points. The theme could be placed near these golden ratio points.
From the perspective of image division, taking a photo with a ratio of 3:2 as an example, a diagonal line could be drawn, and then a vertical line could be drawn from one of the other two corners to the diagonal line to divide the picture into three parts. When the area ratio of the two parts was approximately 0.618:1, if the main scenery was divided according to this ratio, the photo would have a sense of beauty.
In addition, the golden composition point was also based on the application of the golden ratio. After the golden ratio was applied to the photo, the vertical line from a corner to the diagonal was the golden composition point. When the main scenery was placed on the composition point, it could make the main body stand out. There were usually four such golden composition points in a picture, and it had to be applied flexibly according to the actual situation.
If the main body of the photo was not obvious or scattered, there was another simplified form. That was to draw a line from the golden composition point and let the main body be distributed on this line. This was the case for the three-point composition. The picture could be roughly divided into three parts, one part for the sky, two parts for the water, and the main body was in the middle of the water. In actual shooting, there was no need to strictly divide the picture into three parts. One area would take up 1/3 of the picture, and the other area would take up 2/3. The upper and lower positions of the three-point line could be flexibly adjusted according to the subject.
