RT means RunTime error

In the ACM competition, RT means runtime error, usually an array problem.

In most OJs, this kind of error often occurs in acmers questions.

Therefore, when acmers discusses a topic, for convenience and speed, acmers will use RT to submit his code on behalf of him

Return a runtime error.

rt stands for customer relationship technology

RT is a new concept advocated by NCR, which can help merchants integrate customer information Transformed into customer knowledge, and then into customer understanding, and finally into customer relationships; RT is specially proposed to expand and improve customer relationships, it can help merchants better understand and serve their customers. RT helps merchants collect data from every transaction, whether the transaction occurs online, over the phone, at a customer interaction point like an ATM, or through a traditional sale. The data warehouse is the engine of RT. As business needs continue to grow, the scale of the data warehouse is also expanding. NCR has established a 101TB data warehouse for Wal-Mart, the world's largest retail store.

RT is the English abbreviation of blood routine.

Blood routine

Mainly related to blood problems, such as whether there is infection in the body, whether there is anemia, and whether there is the possibility of blood disease. This depends on your condition and combined with routine blood tests.

2. Bleeding time measurement (BT)

[Normal reference value]

[Clinical significance]

Prolonged bleeding time is seen in massive platelet reduction and platelet function defects, acute leukemia, scurvy, etc.

3. Coagulation time measurement ( CT)

Activation method: 1.14-2.05min; test tube method: 4-12min.

[Clinical Significance]

Prolongation is seen in the lack of coagulation factors, the presence of anticoagulant substances in the blood circulation, enhanced fibrinolytic activity, and poor thromboplastin generation.

Shortening is seen in hyperlipidemia, hyperglycemia, cerebral thrombosis, venous thrombosis, etc.

In mathematics, Rt refers to a right angle.

Method to prove the congruence of RT triangles:

Example:

∵ in △ABC and △DEF

∠A=∠D =90°

∴ΔABC and ΔDEF are right triangles

∵In RTΔABC and RTΔDEF

AD=DE

BC=EF

∴RTΔABC≌RTΔDEF (HL)

RT=real time means real-time. Commonly used to describe operating systems (Real-time operating system). RT is actually just a relative concept, which means that the delay is not enough to cause an impact. Real-time operating systems are often used in the control field. For example, VXworks, RTlinux, etc.

[Edit this paragraph] 7. Interpretation 7

Rt=retention time.

It belongs to the term chromatography in analytical chemistry. It refers to the time from the injection of the sample component to the maximum concentration value of the component after the column. It is also the time from the injection to the peak of the chromatographic peak of a certain component. The time elapsed up to this point is called the retention time of this component, represented by Rt, and is often measured in minutes (min) as the time unit. Retention time is determined by thermodynamic factors in the chromatographic process. Under certain chromatographic operating conditions, any substance has a certain retention time, which has the same function as the ratio shift value (Rf) and can be used as a qualitative basis. . Generally, the larger Rf is, the smaller Rt is.

rt=retweet

Twitter is a social network and micro-blogging service. Users can enter text updates of up to 140 characters via SMS, instant messaging, email, the Twitter website or Twitter client software (such as Twitterrific). Twitter was founded in San Francisco in March 2006 and was developed by a company called Obvious Corp. Each text update is displayed on the user page and is visible to every user instantly. Although the user can set the text to be sent only to his friends, the default is that everyone can see it. Users can obtain text updates through the Twitter website, instant messaging, SMS, RSS, email or Twitter client software. Temporarily, the mobile SMS update service is free only in the United States, Canada and the United Kingdom. (Except SMS fees from mobile phone providers)

Twitter was originally a research project of Odeo Company, led by Noah Glass and Jack Dorsey, and launched in March 2006. The Twitter development team won the 2007 South by Southwest award in the Web Blog category. [1] After winning the award, it received reports from different media, including the Wall Street Journal. [2] Twitter is written using Ruby on Rails.

"Retweet" is a term exclusive to Twitter. Retweet means "forward". When you post something, people think it makes sense and want to help spread the word. You can send a "Retweet" (it can also be written as "rTwT" or "RT"). This message is actually just an ordinary Twitter message. Just add the word "RT" in front of it. Your followers will automatically see you. "Forward" this message and generate a conversation with you. It actually makes sense to use Retweets as the basis for status. Just like ordinary websites, search engines will also consider how many times a single article has been linked to for extra points. This number of "Retweets" is also quite similar to "being linked to." "How many times" means.

radiographic testing; RT

Radiographic testing

is the use of rays to penetrate objects. A flaw detection method that finds internal defects in objects.

Rays can sensitize film or excite certain materials to fluoresce. Rays attenuate according to certain rules during the process of penetrating an object. The relationship between the attenuation degree and the ray photosensitivity or fluorescence excitation can be used to detect defects inside the object.

Radiographic flaw detection is divided into X-ray flaw detection, gamma ray flaw detection, high-energy ray flaw detection and neutron ray flaw detection.

Rays are harmful to the human body. During flaw detection operations, relevant safety operating procedures should be followed and necessary protective measures should be taken.

The working voltage of X-ray flaw detection equipment is as high as tens of thousands or even hundreds of thousands of volts. Pay attention to the danger of high voltage during operation.

Radiographic flaw detection (x, γ) method (RT)

One of the common non-destructive testing methods in industry. It refers to the use of electromagnetic waves to detect metal workpieces, similar to X-ray fluoroscopy. The rays pass through the material and reach the film, which will make the film evenly sensitive to light; if it encounters defects such as cracks, holes, bubbles and slag inclusions, dark shadow areas will be displayed on the film. This method can detect the size and shape of defects and also determine the thickness of the material.

X-rays are excited by an x-ray tube plus high voltage. The intensity of x-rays can be adjusted by applying voltage and current.

Gamma rays are excited by radioactive elements, and their intensity cannot be adjusted, but only decreases exponentially with time.

Radiographic flaw detection requires the use of radioactive sources to emit rays, which is extremely harmful to people. Careless operation may cause personnel to be exposed to radiation and increase the probability of suffering from leukemia.

Operators should wear protective clothing and pay attention to the proper storage of radioactive sources.
