indicator pointThe indicator points had many meanings. From an explanation, it could mean a notation mark. When it comes to expressions such as " A-dot," it is a concept of peripheral indicators. In a specific context such as rock strength test, there is a concept like point load strength index, which is a strength index value obtained from the test. It can be used to classify rocks or sometimes replace the uni-directional compression strength. In the financial field, there are various indicators such as momentum strategy that involve the analysis and judgment of market conditions. In terms of medical health, various disease indicators were used to judge the condition and the basis of medication; in terms of trading, there were accurate trading point indicators to judge the trend of long and short; in terms of education, there were also indicators related to the allocation of places in the middle school entrance examination.

An indicator of hemothinningThe indicators that reflected hemothinning were different in different situations:
1. In acute normovolumic hemothinning (ANH), there was no direct mention of specific indicators that reflected hemothinning. However, it was a process of collecting blood from the body and storing it for future use. At the same time, an equal volume of colloid solution or an isonotic crystalline solution was injected to supplement the blood volume to make the blood diluted appropriately.
2. In the blood hCG test, because the hCG concentration in the blood is particularly high, the blood needs to be diluted a certain number of times before the test is done. The normal reference value is related to the number of weeks of pregnancy, such as 3rd to 4th week of pregnancy 500 - 10000 IG/L, 4th to 5th week of pregnancy 1000 - 50000 IG/L, 5th to 6th week of pregnancy 10000 - 100000 IG/L, 6th to 8th week of pregnancy 15000 - 200000 IG/L. 10000 - 100000Iu/L in the second to third month of pregnancy. The normal reference value range of the blood thinning ratio and the corresponding week of pregnancy could reflect whether the blood was in a relatively "diluted" state. If the blood thinning ratio was inappropriate during the test or the final result was not within the reference value range of the corresponding week of pregnancy, it might mean that there was a problem with the blood thinning or other physiological abnormalities.
3. When fasting blood samples were taken to detect relevant indicators, drinking a large amount of water may dilute the blood and affect the measurement results of certain indicators, such as blood sugar, blood fat, liver function (some markers such as jumped), blood serum, blood Na, etc. These indicators had their specific ranges under normal circumstances. If the measurement value deviated from the normal range due to blood thinning, it could be inferred that the blood had been diluted. For example, if a healthy person's fasting blood sugar and blood fat levels had a normal range, if the blood sugar and blood fat levels measured after the blood was diluted were significantly lower than the lower limit of the normal range, it might indicate that the blood thinning had affected the test results.

Jade merchants are struggling to buy and sellIn the process of buying and selling jade, jade merchants indeed faced many entanglements.
From a sales point of view, the pricing was very complicated. On the one hand, he had to leave some profit margin for himself. On the other hand, he had to make the price seem sincere and prevent himself from being compared by his peers. Therefore, when he first played with the customer, he had to give the price so that the customer would not be scared away and there was room for negotiation in the subsequent bargaining. For example, if the customer quoted a very low price of 50% or even 30% off, the jade merchant might adjust the bidding strategy and use the " feeding price " to double the real price. Moreover, in the face of different bargaining strategies from different customers, the jade merchants had to facilitate the transaction and ensure their own interests. When making concessions, they had to make the customers feel that they were good at bargaining, so as to achieve the goal of a win-win situation. If it was a customer who might buy multiple times, the price strategy for the first transaction also needed to be considered. If the price was too low, the next transaction might not be able to provide a good discount.
From a purchasing point of view, jade merchants would also be conflicted when they encountered jade that they liked but the price was slightly higher than expected. Especially when doing business with the seller for the first time, if he paid the full price generously, although the price was higher, it would be beneficial for the next deal. If he haggled too much, he might lose the jade and affect the subsequent cooperation. In addition, there were some special trading modes in the jade trade, such as " borrowing goods for sale." Although it was common, it was easy to exploit loopholes and create fraud cases. This also reflected the dilemma of jade merchants in trading modes. They wanted to expand their sales through this mode, but they were also worried about the risks involved.

water flow indicatorThe water flow indicator, also known as the oil flow indicator, was a sight glass type instrument valve. In industrial production pipes (such as oil, chemical, chemical fiber, medicine, food, power plants, and pump fields), the turbid degree and flow of liquids, gases, steam, and other media can be observed through the window. The flow rate of the medium can also be roughly understood according to the speed of the impellers. It is an important pipe accessory to ensure normal production and product quality. The connection methods were threaded, flange-type, and welding-type.
In the automatic sprinkling system, the water flow indicator is an alarm device that transforms the water flow signal into an electrical signal. It is only used in closed systems (such as wet systems, dry systems, pre-action systems). The rain system (open system) does not have a water flow indicator. When the water or gas in the pipe network on the side of the system flows, it will be triggered, and the input module connected to it will act and feedback signals to the fire control room, so that the firefighters can arrive at the fire scene in time to extinguish the fire. If the action feedback is triggered due to a fault, it needs to be checked and repaired in time to avoid misjudgment in case of a real fire.
In the calculation of fire zones: if a certain alarm valve group protects multiple fire zones, each zone should be equipped with a water flow indicator; if the alarm valve group protects a zone and crosses the floor, each floor should be equipped; if the alarm valve group protects a zone and does not cross the floor, it generally does not need to be set (after the alarm valve group acts, the pressure switch can feedback the signal to the host, which can represent the water flow indicator), but it can also be set. Model XXJZ water flow indicator uses the flow of water in the spray pipe network to push the blade to touch the micro-switch, converting the water flow signal into an electrical signal and connecting it to the controller to start the automatic fire alarm system. It can detect the operation of the automatic spray system and determine the fire area. In addition, there were different types of water flow indicators, such as the water flow indicator that Weilong had obtained a utility model patent for plastic pipes. The working principle was that when a fire occurred and the water flow in the pipe was caused by the explosion of the showerhead, the water flow indicator on the horizontal pipe would play a role.
