1. Diesel test items and indicators
1. Kinematic viscosity: Indicates the viscosity of fuel oil. Viscosity is the main basis for classifying fuel oil grades and is also a fuel Important quality indicators of oil.
2. Moisture: Indicates the water content in the fuel oil. Moisture will reduce the calorific value of the fuel oil and corrode related parts of the equipment.
3. Flash point: the lowest flash point of volatile gases in fuel oil, a safety indicator of fuel oil, and also reflects the content of light components in fuel oil. .
4. Chroma: The depth of diesel color. The depth of diesel color can often indirectly reflect the quality of diesel refining.
5. Density: the ratio of fuel oil mass to volume, an important basis for fuel oil measurement, and an important indicator for measuring fuel oil components.
6. Freezing point: the lowest temperature at which light fuel oil does not flow. It measures the low-temperature fluidity index of fuel oil and is the main basis for classifying diesel grades.
7. Acidity: Indicates the amount of acidic substances contained in fuel oil. Too high acidity will corrode equipment and is also an important quality indicator of light fuel oil.
8. Distillation range: Indicates the distribution of each component in light fuel oil. It is an important method to determine the components of fuel oil. The most important thing about fuel oil isQuality Index.
9. Carbon residue: The residue formed after the evaporation and pyrolysis of fuel oil. There is a lot of carbon residue in fuel oil, indicating that the fuel oil is easily oxidized to form colloid. Or carbon deposits.
10. Ash content: Inorganic matter obtained by calcining the carbonized fuel oil residue. Excessive ash content will form scaling and aggravate the wear and tear of equipment. Affect the normal operation of the equipment.
11. Mechanical impurities: Insoluble sediments or suspended solids in fuel oil. The presence of mechanical impurities will block the oil filter, aggravate the wear and tear of the equipment, and affect the performance of the fuel oil. combustion.
12. Sulfur content: The content of sulfur and its derivatives in fuel oil is an environmental indicator and an important quality indicator of fuel oil.
13. Oxidation stability: used to indicate the oxidation stability of distillate fuel oil. The antioxidant capacity is an important quality indicator of diesel and can reflect the colloid quality of diesel. Generate tendencies.
14. Cetane number: a measure of the ignition performance of diesel, an indicator of the ignition performance and working ability of diesel in the engine.
15. Calorific value: The amount of heat released when a unit weight of fuel oil is completely burned. The level of heat energy generated by the fuel oil is the main indicator for evaluating the quality of the fuel oil. .
16. Metal element content: The content of metal elements such as Al, V, Si, etc. in fuel oil is limited. Yes, it is harmful to the equipment.
2. What are the heart blood test indicators
The most intuitive Cardiac blood test indicators are cardiac enzymes, including troponin, creatine kinase, creatine kinase isoenzymes, etc. Cardiac enzymes can determine the degree of myocardial damage and are an important item in the diagnosis of coronary heart disease, angina pectoris, myocarditis, and myocardial infarction. examine. BNP is also a commonly used cardiac blood test indicator and is specific in the diagnosis of heart failure. Blood lipids include triglycerides, cholesterol, and high low-density lipoprotein. These tests can determine the degree of arteriosclerosis.
3. Various indicators of main coking coal
1. Coal Medium moisture is divided into internal moisture, external moisture and crystallizationwater and decomposed water.
2. Excessive moisture in coal is not conducive to processing, transportation, etc. It will affect thermal stability and heat conduction during combustion, and will reduce coke yield during coking. and extended coking cycle.
3. It is not the total number of minerals in coal, but the chemical and decomposition residues of these minerals.
4. High ash content indicates that the combustible components in coal are low. The calorific value is low.
5. The third indicator: volatile matter (full name is volatile matter yield)
6. It refers to the products after thermal decomposition of organic matter and some minerals in coal. Not all of them are inherent components in coal, but some are pyrolysis products, so it is called volatile yield.
7. The size of volatile matter is related to the degree of coal deterioration. The higher the degree of coal deterioration, the lower the volatile yield.
4. The meaning of coal laboratory indicators
1. Coal Laboratory indicators include coal\’s calorific value (calorific value), sulfur content (sulfur content), ash, volatile matter, fixed carbon, coke slag characteristics, total moisture, analytical water, etc.
2. The moisture of coal is divided into two types. The internal moisture is converted from plants into coal and external water is produced during the mining, transportation and other processes. Moisture attached to the coal surface and cracks. The size depends on the meltability of coal ash, the gas evolution during the formation of the colloid and the air impermeability of the colloid.
5. How to read the routine stool test indicators
Do routine stool tests The examination is mainly to see whether there are white blood cells in the routine stool examination and whether occult blood is positive. If the white blood cells are increased, it means there is bacterial infection. If the occult blood is positive, it means there is blood in the stool. You can take it under the guidance of a doctor according to the test results. medical treatement. You should eat regularly and eat more fruits and vegetables.
6. Which indicator to look at for blood sugar in physical examination
Look at blood routine for blood sugar examine. Blood sugar is an important test method for diagnosing diabetes. For patients with typical diabetes, the fasting blood sugar value is greater than or equal to 7.0 moles per liter.If the blood sugar is greater than or equal to 11.1 moles per liter in the next two hours, it may be diabetes. Normal blood sugar requires a fasting blood sugar of greater than or equal to 7 moles per liter and a 2-hour postprandial blood sugar of greater than or equal to 11.1 to meet the diagnostic criteria.
