翻译好了应该是这样的： SRM control system needs more road isolation power, the paper TOP Switch Ⅱ analysis of the internal structure and working principle is based on a TOP Switch Ⅱ monolithic switching power supply. TOP Switch Ⅱ use as a master design of the SRM control system of multi-output switching power supply and its peripheral circuits. Testing showed that the separation of power, and output stability, to meet the electrical control system of multi-channel power supply needs.

不对之处还望见谅啊！ The waterproofing works are a systems engineering, it involves to the waterproofing material, the waterproofing works design, the construction technique, building's management and so on each aspect.The construction waterproofing works' duty is synthesizes the above various aspects the factor, carries on the omni-directional appraisal, the choice conforms to the request high performance waterproofing material, carries on reliably, durable, reasonable, the economical waterproofing works design, the earnest organization, the careful construction, consummates the service, the maintenance care system, satisfies the building and the construction waterproof serviceable life, realizes the waterproofing works high grade and the good combined earnings.At the same time, the waterproofing works construction is a request high specialized technology, therefore the construction specialization is guarantees the roofing waterproofing works quality the key, if the construction operation is not earnest, the technology is insufficient, its consequence causes the waterproofing works inevitably the defeat. “the design is the soul, the material is the foundation, the construction is the key, the management is guarantees”. The waterproofing works are a systems engineering, the waterproofing works design duty and the request are, works out the economical reasonable waterproofing plan scientifically, takes the practical effective structure measure, guaranteed that the waterproofing works do not seep, and achieves the reasonable serviceable life.Through the diagnosis, the discovery roofing leakage's reason is various.Summarizes, the leakage reason includes: a. old waterproof layer aging expiration; the b. basic unit dehiscence causes the seep; c. divides the warehouse seam, the subsidence seam seep; d. parapet wall wall dehiscence seep; after the e. heat insulating layer enters the water, causes the chain-reaction; f. falls the drainage opening to be too small, draining water is impeded, flows in backward the water. For many years, our country house leakage question has been the quite prominent question.Many newly completes the project had the serious leakage situation, completion has had in the past the leakage house to occupy 60_; The old construction mostly uses the organic waterproofing, now oneself to service life, thus always constructs the leakage phenomenon is more serious.Many units solve the old construction leakage means are use patching materials and so on asphalt felt, SBS modifying asphalt flexible linoleum, neoprene to infiltrate the leak to carry on patching.However the patching leakage often must be much more difficult than the new construction's waterproofing, often is here makes up there leaks, as soon as makes up makes up again, makes the user to be unable to live relieved, the formation " repairs year after year, leaks year after year " the condition, uses in the roofing waterproofing the maintenance cost reaching as high as 1,000,000,000 Yuan every year.
