Hibernate three states of distinction, and the use of save,update,saveorupdate,merge, etc.There are 3 types of Hibernate objects: Transient (Transient), persistent (persistent), and off-state (Detached). Objects that are in persistent state are also known as PO (Persistence object), and instantaneous and de-tube objects are also known as VO (Value object).Instantaneous stateA Java object that opens up memory space by the new command,eg. person person

to 1A or so, and then plug in the power, gently touch with the hand to find the heating elements, such as find, replacement, if you can not find the obvious components, increase current, continue to find. 3 maintenance of common short-circuit components: Ceramic capacitance: Ceramic capacitor is multilayer chip structure, the principle is that two charged conductor close to each other, insulation, will accommodate the charge. And the two ends of the capacitor are not able to pass. ceramic Cap

this abnormal display phenomenon, How can we quickly and effectively get the display working back on track? From the above display fault phenomenon, the author estimates that most of the fault is the picture tube attached to the work circuit has been damaged, because the focus of the cathode ray tube voltage is very easy to happen similar to the above fault phenomenon, causing this fault phenomenon is mai

Computer monitors for a long time, a variety of small problems will follow. Experts believe that to solve the small problems is actually very simple, with a pair of eyes and patience to troubleshoot the problem can be identified. This article is mainly for the display of common fault maintenance skills Daquan for everyone to explain, I hope you like! Computer Failure Repair Daquan: The maintenance skills of the common malfunction of the monitor Common fault One: the computer just when the

During the establishment of a LAN, according to the general specification of Integrated Wiring, the construction should use a network cable with a "meter" or a special "shaped number tube" at the crystal head on both sides ", the computer identification records corresponding to the "meter mark" or "number tube" are also recorded in the cabinet. The number of computers in many units was very small, and some

single-mode and multimode optical fibers comply with all industrial standards.The 900 μm tightly buffered coat is easy to connect and strip.Optical fiber with independent TIA color encoding in the casing.The lightweight single-channel structure saves space in the tube, and water gel is injected into the tube to prevent water leakage.Both design and testing are based on the Bellcore GR-20-CORE standards.The

manpower, but also solve the problem.Come down and tell a real story:Suppose you are an air tube at an airport, you need to manage all the routes to your airport, including inbound, outbound, some flights need to be on the tarmac, some flights need to go to the boarding gate to pick up passengers.What would you do?The simplest way is that you go to recruit a large number of air-control staff, and then each eye on an aircraft, from the incoming, pick-

"Electromechanical drive Control" large operation-mechanical building Elevator control project (Phase 1)Hu Hengxiang Machine Android 1301first, the system hardware interface definition　　According to the operating characteristics of the elevator system, the hardware interface of the system can be divided into floor hardware interface, elevator internal hardware interface and power part hardware interface.1.1 Floor Hardware interfaceEach floor of the elevator has two buttons "upstream" and "downli

Why does the crowded of the pipe need heat?Transfer from http://diy3dprint.blogspot.tw/2014/01/blog-post.htmlFrom the j-head tube, the plastic that is glued to the inside of the Teflon tube after the backflow. This is the crowded out of the head stuck in the meta-killer.Everyone is excited about the machine, and can quickly start printing. Almost all of them are eager to print before they have a hot fan of

Modern single-chip microcomputer is mainly made of CMOS technology. 1. MOSThere are two types of MOS: N and P. As shown in: Take the n-type tube as an example. The 2-end is the control end, called the "Gate"; the 3-end is usually grounded, called the "source pole"; the source pole voltage is recorded as VSS, and the 1-end is connected to the positive voltage, it is called "Drain pole", and the drain voltage is recorded as VDD. To enable the connec

. This is the internship report I just completed, especially for you. A letter, let you know the real idea of graduate tube, I hope you believe in educational tube help. ---Detonator 1102 Liu Yi FuThe above is just received (20140427) e-mail, the rich is not my graduation design students, last year he and Kai Zhi ("Kai" right there is a "put" the right side of the word, too hard to find pinyin input method

Tm1629 digital tube driver first. I have read a lot on the internet, mostly common cathode. The common cathode is easy to operate, there are few digital tubes under control, and there are many digital tubes under control of common anode, but the conversion is required.

This experiment uses a digital tube to implement the stopwatch timing function, and uses buttons to pause, continue, reset,Enable flashing of LED lights when the digital tube is suspended1. the LED light is controlled by the C port and valid at a high level.2. The bit segment of the digital tube is controlled by port A, and the data segment is controlled by port

insulation Gate Bipolar Transistor are available in the "component" column. (11). Select "Mos Gate switch (IGBT)". The "component" column contains 98 types of MOS door control power switches for calling. (12). Select "n depletion MOS tube (mos_3tdn)". nine types of MOS can be called in the "components" column. (13) Select "n enhanced MOs (MOS _3ten)". There are 545 kinds of MOS in the "components" column for calling. (14) Select "p-channel enhanced M

measured resistance deviation is larger, may be the coil open or short circuit, will cause no needle or out of the phenomenon of weak needle. Testing can be a multimeter of a table pen to the public side, another table pen to the corresponding points of each drive coil, the replacement of a single coil can be used first with a tin-suction device to remove the solder on the coil and then use the blade to cut off the surrounding plastic, remove a single coil, replace it.The main cause of the open

Select the advantages of a flat panel monitor. 　　1, display high quality Because each point in the LCD monitor is received after the signal has been maintained that color and brightness, constant glow, rather than the cathode ray tube display (CRT) need to constantly refresh the highlights. Therefore, the high quality of the liquid crystal display and will never blink, the eye fatigue to the lowest. 　　2, a small amount of electromagneti

the active bottom plate and rubber ball, and then the roller and support wheel, rubber ball on the dirt clean, reload can return to normal. Optical mouse because there is no rotating rubber ball, there is no rotation of the roller, so there is no flexibility due to the rotation of the mouse movement is not flexible phenomenon. However, when the light tube or photosensitive tube accumulated dust too much, a

normally, and small move when the work is not normal, indicating the normal mouse installation, circuit work is normal, the reason is the rubber ball can not effectively drive the grating disk rotation. This is rubber ball, left and right axis, front and rear axle and support wheel is too dirty, causing the rotation is not flexible caused. This is the most likely failure of the mouse. The handling of the fault, as long as the removal of dirt can be. The specific treatment is to flip the mouse,
