instrument:　　 ● Stringy instrument: the brightness is adjusted to 6 kHz and 12 kHz, the fullness is 310Hz and Hz, and the chord sound is 1 kHz and 1 kHz.● Piano: 60Hz and 170Hz bass, 3 K and 6 K on-site sound, attenuation of 12 kHz, 14 kHz, 16 kHz sound thin, and vice versa.● Audio drum: the percussion sound is 3 K, and the bass is 60Hz.● Small drum/high-pitched drum/tambourine: Hz and Hz in fullness, 6 K

Flame SpectrophotometerFlame Photometer is an analytical instrument based on the basic principle of emission spectra. Includes: Gas and flame combustion part, optical part, photoelectric converter and inspection record part. The process is to spray the specimen into the flame by a nebulizer, excite the light, after splitting the light by the detector to measure the emission intensity, the latter is proportional to the content of the element to be meas

[C #] What about OOP polymorphism, Advice to cainiao developers: spend 10 thousand hours practicing Coding and do not waste 10 thousand hours Debugging (that is, reading code) Looking at the above UML diagram, we create an abstract Instrument class with an abstract method paly in the class, and all the subclasses inherit this class and implement the paly method. (If you do not understand inheritance, refer to another article: inheritance of OOP) Let

The management software of the color difference measuring instrument must be linked to the color difference measuring instrument. How can the management software of the color difference measuring instrument be linked. What do you need to pay attention to during the link process? What data and attributes need to be set for the link between the color management sof

Do you have any magic? In fact, there are many implementations of coroutine in the JVM (implementing-coroutines-

constructor for automatic assembly, if it fails, then use Bytype for automatic assemblyByNameLet's look at the difference between the two configurations, the value of the property instrument is a bean that has already been defined in that context, the reference is its ID, and the second method changes the bean's ID to the same name as the Bean property that references it. Then use the byname way to automatically assemble, you can see the second assem

Label:Overview Here are some tips on how to mimic the functionality of document annotations in Java. In Eclipse, the mouse hovers over the class or its members, the relevant documentation comments are displayed, and similar features are available in PL/SQL, and we need to master some annotation techniques to make them more readable. Body 1. Do not write comments on the topThe content before the first valid instruction is directly ignored, is not formatted, and is not stored. If you

is very flattering. having said so much, iCloud seems to be something like a network disk, but there is only one more backup and push update. actually not. although the 5g space is provided to users for free, users cannot "directly" Use it. what I call "direct" means that, like Dropbox, a client allows users to store any file. but iCloud doesn't work. You can store files, but you must use a program. correspondingly, apps with the iCloud function can only access files uploaded by their own progr

This article introduces the knowledge of automatic assembly, spring in order to simplify the writing of configuration files. Automatic assembly mode, automatically loading the required beans. 　　Automatic assembly is available in the following ways:1 ByName The name of the ID and the name of the property, to ensure that the name of the attribute in the bean instance is the same as the ID name of the assembly.2 Bytype determines the assembled bean by type, but when there are multiple types of

in the area of storage, there have been too many new concepts in recent times, including "Software-defined storage", " Server SAN " and" cloud storage ". A lot of concepts make people foggy, unintelligible. So what exactly is software-defined storage? What is a Server SAN? What is cloud storage? In fact, many storage vendors are not well defined, the industry does not have a consistent clear definition. Many of the markets and the media give a macro explanation. In this era of the concept of fly

find. However, in some cases, it is difficult to locate the obstacle location from the abnormal phenomenon on the route. In this case, the distance between the obstacle point and the test point must be measured based on OTDR, and the original test data must be checked, find out the block where the obstacle point is located, and then accurately measure the ground distance between the points through necessary conversion until the specific location of the obstacle point is found. However, the obst

levels of the cable after water accumulation change as high and low as the waves, the change amount depends on the degree of wet water of the cable.2. Coaxial Cable Fault Detection MethodUse the QXZ04 tester to find the fault point. The QXZ04 cable fault tester is a digital instrument used to measure the cable fault. It uses the reflection principle of the transmission line to determine the fault point of the cable in the time domain. Easy to use and

This paper describes the design of the controller based on RS232 interface. It uses a single-chip microcomputer to control the interface chip nat914, and uses SCPI statements in the Super Terminal of the serial communication tool that comes with the winelows operating system, the communication and program-controlled operation between the computer and the Kaplan instrument is realized.
