The invention discloses an energy-saving high-speed railway train working diagram adjusting method based on a stop scheme, and belongs to the technical field of high-speed railway train running schemes. In the invention, the station stop rate is determined according to passenger flow, the energy consumption value increased by train stop of each intermediate station is calculated, a double-target optimization model (the travel time is the shortest and the energy consumption value is the smallest) is established, and stop adjustment suggestions are given in combination with the relevance betweena high-speed railway train stop scheme and the energy consumption value. On the premise that the high-speed railway train meets the requirements for safety intervals, passenger flow and the like, energy conservation and emission reduction are achieved, the train travel time is shortened, and the route passing capacity and the passenger travel comfort are improved.

The invention provides a water outlet set temperature control method and a system of an air conditioning system, wherein the method comprises the steps of: obtaining a detected outdoor environment temperature value and an upper limit value and a lower limit value of set environment temperature set by users, judging and comparing if the outdoor environment temperature value is greater than or equal to the upper limit value of the set environment temperature or smaller than or equal to the lower limit value of the set environment temperature, and controlling the water outlet set temperature according to the judging and comparing result. The method can associate the water outlet set temperature with the outdoor environment temperature, and the water outlet set temperature is changed along with the change of the outdoor environment temperature, so that an air conditioning unit can satisfy the user requirements on the water outlet set temperature under various environment temperature conditions, the over-range operation of the air conditioning unit is prevented, and the use comfort and the reliability of the air conditioning unit are improved.

The invention discloses a connector and a manufacturing method thereof. The method comprises the steps of: firstly, providing a substrate, wherein the substrate is provided with a first surface and a second surface which are opposite, and a through hole; secondly, forming a first electric-conductive layer on the substrate, wherein the electric-conductive layer covers the inner wall of the through hole; thirdly, filling a hole-plugging material in the through hole to form a hole-plugging column; fourthly, forming an electric-conductive elastic suspension arm on the first surface, and electrically connecting the electric-conductive elastic suspension arm with the first electric-conductive layer; fifthly, forming a gold-plated layer on the electric-conductive elastic suspension arm and the first surface, forming a solder ball on the second surface, and electrically connecting the solder ball with the first electric-conductive layer, wherein a free end part of the electric-conductive elastic suspension arm and the solder ball are positioned on a vertical line perpendicular to the first surface.

The invention belongs to the technical field of functional finishing for household storage fabrics, and particularly relates to a dyeing and finishing process for a microfiber suede fabric for household storage. The process comprises the following steps that step 1, pretreatment refinement, presetting, reduction splitting and sanding and processing are carried out on greige cloth fabrics; step 2,inflaming retarding dyeing one-bath processing is carried out; step 3, reduction cleaning processing is carried out; step 4, antifouling and anti-mold anti-bacterial processing is carried out; step 5,centrifugal dewatering, shaping, brushing and rolling are carried out, and a product is obtained. The dyeing and finishing process starts with aspects of technical process, processing mode, functional addition agent selection, assistant agent addition and the like, mutual influences among various factors are avoided, contradiction among various functions is solved, and a multi-functional composite high-performance product is finally obtained; as for the processing mode, dip dyeing instead of pad dyeing is adopted, it can be avoided that the cloth surface nap of the fabric is rolled and flattened so as to ensure full, soft and exquisite feeling of the final product.
