Cp pairing test, what does the CP pairing reminder in QQ mean?

Speaking of cp pairing test, we all know that someone asked what the CP pairing reminder in QQ meant. In addition, some people want to ask how to calculate CP and CPK, and what is the difference. What do you think this is? In fact, can the results measured by different viscometers be converted between mpa.s and cp? 50mpa.s？ Let's see what the CP matching reminder in QQ means. I hope I can help you!

Cp matching degree test

1, cp matching test: What does the CP matching reminder in QQ mean? CP matching means becoming a partner, and QQ pops up such a reminder, suggesting that you are more likely to become a partner than mainstream Microsoft Windows, macOS, Android, iOS, WindowsPhone, Linux and so on. Fitting test of its standard cp name.

Chi is a little penguin wearing a red scarf. Tencent QQ supports online chat, phone call, point-to-point breakpoint continuation and text sharing.

Software, network hard disk, custom panel, QQ mailbox and other functions, and can be connected to a variety of communication terminals. On October 5th, 65438/kloc-0, Teng entered his name to test the abo attribute.

QQ and Midea Group formally signed a strategic cooperation agreement in Shenzhen. Object matching test.

2.cp matching test: how to calculate CP and CPK, what is the difference? CP CAn only calculate CPK if ca is obtained first. The calculation formula is: CPK = CP (1-| CA |). Measure the matching degree of couple photos.

According to the formula: Ca=(X-U)/(T/2), the accuracy of Calculation process: by measuring the value of ca, you can measure your abo sex and pheromone for free.

According to the formula: Cp=T/6, calculate the process accuracy: whether the Cp value is suitable for two people is freely tested.

According to the formula: Cpk=Cp( 1-|Ca|), the process capability index: Cpk value is calculated.

The difference between CP and CPK:

Cp: Short-term process capability index without considering deviation (the average value is the central value of the specification). CP reflects the level of process capability that can be achieved unless systematic measures are taken to eliminate common causes.

Cpk: short-term process capability index considering deviation (the average value is not the central value of the specification). Cpk reflects the actual process capability. The improvement method is to reduce the deviation and often take some local measures to eliminate special reasons to improve the CPK value. Test the marriage match between two people.

The process capability indices Cp and Cpk that we often refer to refer to the short-term capability of the process. Cp refers to the ability of the process to meet the technical requirements, which is usually expressed by dividing the deviation range of customer satisfaction by six six sigma. T= allowable value (Tu)- allowable minimum value (Tl)Cp=T/(6σ)

Therefore, the smaller σ is, the greater its Cp value is, and the better its technological capability is. Cpk refers to the deviation (ε) between the process average value and the product standard specification, which is usually expressed by subtracting the average value from the upper limit deviation value satisfied by customers, then subtracting the lower limit deviation value, and then dividing it by three times Sigma. Couple matching test is free.

Cpk=MIN(Tu-μ, μ-Tl)/(3σ) or Cpk=( 1-k)Cp, where k=ε/(T/2) Generally, the population standard deviation (σ) of the distribution of quality eigenvalues is unknown, so the sample standard deviation (S) should be used instead.

Can the results measured by different viscometers be converted between mpa.s and cp? 50mpa.s？ 1. When selecting the process station Cpk for control, the first factor to be considered is the cost and the influence of its quality characteristics on the subsequent process.

2. The calculated sampling data must have at least 20~25 groups of data to be representative.

3. When calculating Cpk, we should not only collect sampling data, but also know the specification upper and lower limits (USL, LSL) of quality characteristics, so as to calculate its value smoothly.

4. First, the standard deviation (σ) of the sampled data can be automatically calculated by the "STDEV" function of Excel, and then the specification tolerance (t) and the specification center value (u) can be calculated. Specification tolerance = specification upper limit-specification lower limit; Specification center value = (specification upper limit+specification lower limit)/2;

The above is the reminder of matching CP in QQ. What does this mean? Related content is about what the CP matching reminder in QQ means. Share. I saw the cp matching test, I hope this will help everyone!
