Operation method

The standard research method is a general method of accounting theory research. It is an analytical method that judges the behavior results of economic actors and the systems or policies that produce the results according to certain values or economic theories, and answers what the behavior of economic actors should be.

Empirical research method The empirical research method is a research method to recognize objective phenomena and provide people with practical, useful, definite and accurate knowledge. Its focus is to study what the phenomenon itself is. The empirical research method attempts to surpass or exclude value judgment, only reveals the internal constituent factors of objective phenomena and the universal connection of factors, and summarizes the essence of phenomena and their operating laws.

Case analysis method Case analysis method refers to the training method that takes problems in actual work as cases, gives them to trainees for research and analysis, and cultivates their analytical ability, judgment ability, problem solving ability and business execution ability. Specifically

Comparative analysis is an analytical method that prompts the difference between the actual number and the base through the comparison between the actual number and the base, so as to understand the achievements and problems of economic activities. It is often used in scientific inquiry activities. It is similar to the equivalent substitution method.

Thinking method Thinking method is an important tool for people to think correctly and express their thoughts accurately. The most commonly used scientific thinking methods in scientific research include induction and deduction, analogical reasoning, abstract generalization, thinking and imagination, analysis and synthesis, etc. It has universal guiding significance for all scientific research.

The object of scientific research is the unity of quality and quantity. Their quality and quantity are closely linked, and qualitative change and quantitative change are mutually restricted.

Q: How thick is the endometrium to be pregnant

Answer:
Answer: The normal thickness of the endometrium is 8-12 mm. The endometrium thickens a few days before the menstrual period. Only when it is no less than 0.8 cm in the ovulation period will there be a chance of pregnancy. If it is greater than 1.4 cm, it cannot be pregnant. After calculating the ovulation period, the probability of pregnancy in the next day sex life during ovulation period is greater than that in the general sex life one week later, you can make a blood HCG diagnosis to determine whether you are pregnant. The blood HCG is relatively accurate. The endometrium changes periodically under the action of estrogen secreted by the ovary. Ovarian hormone secretion is cyclical, that is, when menstruation is just coming, the level of estrogen is relatively low. With the clean menstruation, the gradual development of ovaries and follicles, the hormone level begins to rise, and the endometrium begins to thicken gradually. By the time of ovulation, the endometrium will further thicken, preparing for ovulation and fertilization.
