The composition and proportion of the bleachers
The 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 castable
The 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.

Life and speed should be in proportion
According 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 teachers
Taking 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.
