FWD has three meanings, which are "drop weight deflectometer", "freewheeling diode" and "front-wheel drive".

1. Drop weight deflectometer.

1) Basic introduction.

FWD (Falling Weight Deflectometer, referred to as FWD), that is, falling weight deflectometer, is one of the most advanced nondestructive testing equipment for pavement strength in the world. Falling weight deflectometer to measure the dynamic deflection of the pavement and calculate the rebound modulus of the pavement has become a hot topic in the road industry around the world.

The U.S. Strategic Highway Research Program (SHRP) also uses FWD as a means of strength evaluation and tracking detection of 2000 test roads, and uses the back-calculated resilience modulus of FWD as a benchmark to research and develop an indoor test method for the resilience modulus of materials. In recent years, FWD has also been introduced and put into use in China, showing strong vitality and superiority.

2) Working with slip principle.

The drop weight deflectometer starts the drop weight device through the hydraulic system under the control of the computer system, so that the drop weight of a certain quality falls freely from a certain height, and the impact force acts on the bearing plate and transmits to the road surface, thereby exerting pulse load on the road surface, resulting in instantaneous deformation of the road surface.

Sensors with cracks distributed at different distances from the measuring point detect the deformation of the surface of the structural layer, and the recording system transmits the signal to the computer, that is, to measure the dynamic deflection and the deflection basin generated under dynamic load. The test data can be used to calculate the modulus of the pavement structure, so as to evaluate the bearing capacity of the pavement scientifically.

2. Freewheeling diode.

FWD (Freewheeling Diode), which is commonly referred to as a "freewheeling diode", is named because it plays a freewheeling role in the circuit, and generally chooses a fast recovery diode or Schottky diode as a "freewheeling diode".

It is generally used in the circuit to protect the components from being broken down or burned out by the induced voltage, connected to the two ends of the components that generate the induced electromotive force in parallel, and form a loop with it, so that the high electromotive force generated by it is consumed in the circuit in the way of continuous current, so as to protect the components in the circuit from being damaged.

3. Front-wheel drive.

FWD (front-wheel drive), i.e. front-wheel drive, accounts for 70% of sedan products today. Both economy and mid-range sedans are equipped with front-wheel drive. As the name suggests, only the front wheels of the Pepper deliver power.

The engine installed in the front transmits power directly to the front wheels, improving traction efficiency, and 60% 70% of the weight is concentrated in the front of the car, providing better ice and snow stability, but the front wheels have to withstand 75% braking, and the center of gravity of the body shifts back when accelerating sharply, which will cause acceleration delay, and there is also understeer and front wheel slippage in handling.

1. DF is: DON'Abbreviation for t fragment.

df:don'T fragment is the first "flag" of the IP protocol, and the flag occupies 3 bits, and only the first two digits are meaningful. The lowest bit of the flag field is mf (more fragment).

mf =1 means "there are still shards" at the end. mf = 0 means the last shard. The middle digit in the flag field is df (don't fragment) sharding is only allowed if df = 0.

2. DF is the abbreviation of the Development Finance major of the University of Manchester, that is, MSC Development Finance.

Offered by the School of Environment and Development, the Development Finance programme at the University of Manchester focuses on theoretical approaches to economic development issues, key issues, and provides the necessary skills and theoretical guidance for policy formulation and implementation by focusing on financial development policy and financial management, particularly for developing countries, as well as learning to use different methods, analyses and presentation of data to assess specific issues and associated evidence and information.

3. Language requirements: IELTS requirements for applying for this course with no less than a score in each component (no less than a score in the written test).

FDC is the English abbreviation of floppydiskcontrol, which translates into Chinese as floppydisk controller.

Floppy disk controller, also known as floppy disk controller (fdc), is a special function of the chip, which is composed of disk controller circuits that control reading and writing to computer soft disk drives.

In the 1980s and 1990s, floppy disk controllers were commonly used in personal computers or IBM PC-compatible models such as the NEC PD765, Intel 82072A, or 82072A and their successors. In addition to the ones listed above, other floppy disk controllers may have a concept or implementation that is structurally identical.

A floppy disk controller board can control up to four floppy disk drives, the controller is connected to the computer's system bus, and provides an IO port to the processor. It is also generally connected to a direct memory access controller. On x86 PCs, the floppy disk controller uses interrupt service 6 to call on other systems, and other interrupt service methods may also be used.

Floppy disk controllers typically use direct memory access mode to transfer data.

Floppy disk controller functions: floppy disk controller functions, external circuit functions, x86 computer floppy disk controller input and output port, data port, master status scratchpad (MSR), digital control port,"3 modes"Floppy drive.

FB is the abbreviation of "multi-functional audio ** foobar2000 and Facebook", the name of the car club, and also refers to the copy of the online game, in which the abbreviation of ferrobacteria is also FB. At the same time, FB is also called the English abbreviation of "First Blood".

Foobar2000 is a free software developed by Peter Pawlowski (formerly a member of the Winamp development company Nullsoft) and is a versatile audio user. In addition, FooBar2000 also supports functions such as generating libraries, converting file encoding, and extracting CDs. It is a powerful tool.

Foobar2000All functional components are modular design, the default interface uses Win32 GUI, you can freely adjust the control module in the interface according to the needs of ** and control, such as adding visual audio gain effect diagram Spectrogram, Spectrum, Vu Meter, Wheel Hidden OSCILLOSCOPE, etc. All options and commands support shortcut keys, and you can customize menus, making it truly your own style – not just by changing the interface. The open-source component architecture allows third-party developers to extend the functionality of the device by developing plug-ins.

In terms of function, FooBar2000 can achieve automatic gapless, and it performs well in lossless audio. It supports Unicode, supports replaygain, etc., and has the advantage of low memory footprint, which can effectively process a large number of lists.
