A method for managing a user's computing environment on their computer or workstation. The method includes storing a set of files in a memory device accessible via a communications network. Each file includes data such as environment variable values defining a particular computing environment. The method includes providing an environment management engine in a user's home directory of a computer. A shell runs in the computer device to invoke and run a computing environment management engine within the shell. The engine generates a computing environment in the computer based on the computing environment definition in one of the files that is chosen based on a user-provided or otherwise determined job state (e.g., the user is working on a project or a portion of a project that is associated with a job state). The computing environment includes versions of software applications, path variables, and alias definitions.

The invention discloses an electronic-control backlash eliminating gear pair with variable tooth thickness. The gear pair comprises a tooth thickness variable gear I, a tooth thickness variable gear II and an electronic-control backlash eliminating system, wherein the tooth thickness variable gear II is meshed with the tooth thickness variable gear I, the electronic-control backlash eliminating system comprises at least an electronic-control power device used for exerting backlash-regulating axial mechanical force on the tooth thickness variable gear I and the tooth thickness variable gear II, and the direction of the backlash-regulating axial mechanical force is a direction for backlash elimination between the tooth thickness variable gear I and the tooth thickness variable gear II. According to the gear pair, real-time control of axial displacement is achieved through electronic control, then the tooth backlash can be regulated in real time according to backlash regulation requirements, the response is rapid, the transmission accuracy is improved, the volume is small, the structure is simple, the synchronism requirement for control is low, the cost is low, the assembling requirements are easy to satisfy, the tooth backlash and the return difference can be eliminated or reduced timely, the transmission error during reversing can be reduced, therefore the operation and the control are simple and fast, and high adaptability is provided at occasions with high requirements for the integral structure.

The invention relates to a red-blue-light glass ceramic light conversion component. The component comprises a first blue fluorescent glass ceramic body and a second red fluorescent glass ceramic body,wherein the first blue fluorescent glass ceramic body is formed in the way that blue fluorescent powder and phosphate glass powder are mutually mixed and subjected to melting and solidification; theblue fluorescent powder is selected from one or more of a fluorescent material with a molecular formula of BaMgAl<10>O<17>:Eu<2+>, a fluorescent material with a molecular formula of CaF<2>:Eu<2+> anda fluorescent material with a molecular formula of CaAl<2>O<4>:Eu<2+>; the second red fluorescent ceramic body is formed in the way that red fluorescent powder and phosphate glass powder are mutuallymixed and subjected to melting and solidification; the red fluorescent powder is selected from one or more of a fluorescent material with a molecular formula of CaAlSiN<3>:Eu<2+>, a fluorescent material with a molecular formula of Y<3>Al<5>O<12>:Mn<4+> and a fluorescent material with a molecular formula of 3.5MgO.0.5MgF<2>.GeO<2>:Mn<4+>; and the first blue fluorescent glass ceramic body and the second red fluorescent glass ceramic body are mutually spliced to form the red-blue-light glass ceramic light conversion component. The red-blue-light glass ceramic light conversion component can adaptto a near-ultraviolet LED chip to emit blue light with wavelength ranging from 400nm to 500nm and red light with wavelength ranging from 580nm to 780nm; and the peak width at half height of a spectrumof the blue light is up to 50nm, so that the requirement of plant growth is better met, light emitting efficiency is higher, and light quality is easier to adjust.
