人造小太阳可控核聚变作文

人造小太阳可控核聚变作文英文回答：Artificial Controlled Nuclear Fusion.Nuclear fusion, the process of combining light atomic nuclei to form heavier ones, has long been a subject of scientific exploration and research. It holds the promise of providing clean and virtually limitless energy for our planet. In recent years, scientists and engineers have made significant progress in developing controlled nuclear fusion, and one of the most exciting advancements is the creation of an artificial small sun.The concept of an artificial small sun is based on the idea of creating a miniature version of the sun here on Earth. By replicating the conditions found in the core of the sun, scientists aim to harness the immense power of nuclear fusion. The goal is to achieve a self-sustaining fusion reaction that can generate large amounts of energy.To achieve controlled nuclear fusion, scientists use a device called a tokamak. This device consists of a toroidal vacuum chamber surrounded by powerful magnets. Inside the chamber, a mixture of hydrogen isotopes, such as deuterium and tritium, is heated to extremely high temperatures, creating a plasma state. The strong magnetic field confines the plasma, preventing it from touching the walls of the chamber and causing damage.The plasma is then subjected to powerful heating methods, such as radiofrequency waves or neutral beam injection, to increase its temperature and pressure. As the plasma reaches the necessary conditions, the hydrogen isotopes collide and fuse together, releasing a tremendous amount of energy in the process. This energy can be captured and converted into electricity, providing a clean and sustainable source of power.The development of an artificial small sun has numerous advantages. Firstly, it offers a solution to the global energy crisis by providing a virtually unlimited source ofclean energy. Unlike fossil fuels, which contribute to climate change and pollution, nuclear fusion does not produce greenhouse gases or radioactive waste. Secondly,the technology behind controlled nuclear fusion can be used for various applications, such as powering spacecraft or generating electricity for remote areas. Lastly, theartificial small sun has the potential to revolutionize the way we think about energy, paving the way for a sustainable and environmentally friendly future.中文回答：人造小太阳可控核聚变。

4. The design process
Glycine production process a lot of, at present industrialization and has the prospects for industrialization production technology mainly in the chloroacetic acid ammonolysis process, Trey g (cstercker method), hydrogen cyanide, and biosynthesis method etc. This design adopts the method of ammonia chloride solution. The method according to the different raw materials, and can be divided into two processes: (1) alcohol or aqueous phase with methenamine, chloroacetic acid and ammonia (ammonia or liquid ammonia) synthesis as raw material; (2) in the aqueous solution with ammonium carbonate or carbamate amine, chloroacetic acid, ammonia as raw material synthesis. At present, the main production methods in China, the yield of about 70%, the latter yield is low (about 42%), it is rarely used in industrial production. At present, the main production methods in China, the yield of about 70%, the latter yield is low (about 42%), it is rarely used in industrial production. Because of urotropine in aqueous phase synthesis of glycine consumption is larger, and methenamine higher price, can’t be recycled, so cost is higher, and with alcohol solution instead of water solution will greatly reduce the consumption of urotropine, thereby reducing the cost of production. Therefore, the current domestic popular with alcohol phase synthesis of glycine.

Introduction
Dynamical supersymmetry breaking (DSB) oﬀers a natural explanation for the hierarchy between the electroweak scale and the Planck scale. In this context, the “DSB sector” contains the gauge interactions responsible for supersymmetry breaking and the chiral superﬁelds charged under this group, while the visible sector includes the supersymmetric standard model. There are several known models which break supersymmetry dynamically [1, 2, 3, 4], and can be used as the DSB sector. But a model of supersymmetry breaking is not suﬃcient; the supersymmetry breaking must be communicated to the visible sector. At present, there are two scenarios. Supersymmetry breaking can be transmitted from the DSB sector to the visible sector either by supergravity or by gauge interactions. The latter scenario has the virtue of ensuring a natural suppression of ﬂavorchanging neutral currents [5]. Also, if supersymmetry breaking is gauge mediated, the soft breaking parameters are potentially determined in terms of a few coupling constants. However, it is diﬃcult to make a phenomenologically successful model of this type. It is essential to give the gauginos a mass. Current models [2, 6] do so by ﬁrst breaking supersymmetry in one sector, then generating a VEV for the F component of a singlet ﬁeld, coupling this singlet ﬁeld to messenger quarks, leading to a one loop gluino mass of order of the electroweak scale. This is not very economical, and ideally, one would like to construct a model in which the communication of supersymmetry breaking is more direct. However, constructing more directly connected models can prove to be diﬃcult. Were one to try to introduce the messenger quarks into the DSB sector, asymptotic freedom would typically be lost [1]. One could try to eliminate the scalar in favor of a fermion bilinear but that seems not to ﬁt well into models of DSB so far constructed [7]. One might introduce the singlet directly into the DSB sector [4, 8]. But it is not clear that even a locally stable minimum can be constructed which breaks supersymmetry and preserves color. The phenomenology of gauge mediated supersymmetry breaking is the subject of several recent studies [9]. In this paper, we explore another question, namely the stability of phenomenologically successful minima. Our results regarding the properties of the global minima in the simplest known models of this type are presented in the next section. In section 3 we consider the possibility that we live in the false vacuum. More complicated models are discussed in section 4. A summary can be found in section 5.

The Vacua of the Messenger Sector
In the existing models of gauge mediated supersymmetry breaking there is a sector which breaks supersymmetry dynamically at a scale Λs ∼ 102 − 104 TeV. This DSB sector has a global symmetry Gm which is weakly gauged so that it may be considered a small perturbation to the DSB mechanism. Supersymmetry breaking is transmitted from the DSB sector to the visible sector through a “messenger sector”, which consists of a gauge singlet, S , a pair of messenger quarks, q and q ¯, in the 3 and ¯ 3 of the color SU(3)C group, and a pair of chiral superﬁelds, N and P , in vector-like representations of Gm . If there is a (Gm )3 anomaly in the DSB sector, the messenger sector should also include other superﬁelds, Ei , to cancel the anomaly. The superpotential of the messenger sector includes the most general dimension-3 operators: λ Wmes = κS q ¯q + S 3 + λ1 P NS + W1 (P, N, Ei) . 3 (2.1)
The P NS term communicates supersymmetry breaking from the ﬁelds charged under the messenger group to the gauge singlet, and the S q ¯q term links the gauge singlet with the messenger quarks. Couplings of P and N to the other charged chiral superﬁelds are contained in W1 . A discrete or R symmetry is required to forbid linear or quadratic terms in S and a q ¯q term, which otherwise would have coeﬃcients of order the Planck scale. We choose a phase deﬁnition of the ﬁelds such that the coupling constants, κ, λ, λ1 , are positive. We focus on the case Gm ≡ U(1). Let g be the U(1) gauge coupling in the normalization where P , N and Ei have charges +1, −1 and yi , respectively. Upon integrating out the DSB sector, the only presence of supersymmetry breaking in the messenger sector is through an eﬀective potential for the charged scalars [6]:
