The invention relates to a polyglutamic acid fiber with antibacterial property and high water absorption. The main ingredients of the polyglutamic acid fiber comprise modified polyglutamic acid which is a polymer formed from a glutamic acid chain segment and a modified glutamic acid chain segment, wherein the modified glutamic acid chain segment has the chemical structure formula shown by the following formula (I), wherein X is H or Na, Y is Cl, Br or I; and the molar ratio of the modified glutamic acid chain segment to the glutamic acid chain segment is not less than 0.05.

The invention discloses a preparation method for an antibacterial and absorbent polyglutamic acid fiber. The preparation method comprises the following step of: soaking a polyglutamic acid fiber into an aqueous solution of sodium hypochlorite, wherein a relational expression I between the soaking time T of the polyglutamic acid fiber and the concentration X of the aqueous solution of the sodium hypochlorite is that: (T-64.55X<2>+50X) is more than or equal to 10.2 and is less than or equal to 15.2 (I), wherein X=0.006-0.4 percent by weight.

The invention relates to a production method for pepper hybrids. The production method comprises the following steps: (1) sowing seeds of pepper half-sterile line female parent; (2) sowing pepper stock and male parent seeds when the half-sterile line female parent grows for 1.5-2.5 months; (3) removing pollen plants after the half-sterile line female parent flowers; (4) grafting twigs and branches, taken as scions, of the female parent without pollen onto the stock; and (5) performing pollination when the scions and male parent of the grafted seedlings flower, thereby acquiring the pepper hybrids after fruit is ripened. According to the planting method, the problem of 50% of fertile plants can be thoroughly solved; the pollination is timely and efficient; the yield is increased on the basis of ensuring purity; as the grafting position of the stock is under the cotyledon, the growth point of the stock is removed, the operation of cutting lateral branches while pollination is omitted, the risk of influence on purity caused by incompletely cut lateral branches is avoided, the cost is saved, and the seed production is safe.

The invention is applicable to the field of air purifiers and discloses a purifier lifting head structure and an air purifier. The purifier lifting head structure comprises a lifting head component for sealing or opening an air outlet and a power component for driving the lifting head component to rise and descend. The power component comprises a guide fixing plate, a lifting member snapped and inserted on the guide fixing plate in a sliding mode and a power mechanism which is arranged below the guide fixing plate to drive the lifting member to rise and descend. The top end of the lifting member is snapped above the guide fixing plate and in fastening connection with the lifting head component. The bottom end of the lifting member penetrates and extends to the lower portion of the guide fixing plate and is in transmission connection with the power mechanism. By means of the lifting head structure and the air purifier, external impurities such as dust and the like are prevented from being stacked at an air outlet or entering the air purifier from the air outlet when the air purifier is in idle, the purifying effect of the air purifier is guaranteed sufficiently, and the lifting head component and lifting member lifting stability is guaranteed due to the guide action of the guide fixing plate.

This invention provides a method for suppressing hydroxyl condensation and increasing fluidness of phenol tar with chemical measures, which adds alkali metallic compounds in a separation process of phenol hydroxylation reaction solution in 5-60% gross mass of phenol tar in terms of hydrates to be reacted with part of the tar to generate alkali metal phenol salt matters and suppress the dewatered condensation among molecules to keep good fluidness of the tar.

The present invention relates to a gear shift system for a bicycle and, more specifically, to a gear shift system capable of shifting gears of the bicycle through a motor driven method which can use the existing chain gear shift for a bicycle. The gear shift system comprises: a chain gear shift including a rear gear shift controller and a front gear shift controller, with the rear gear shift controller being mounted on the seat stay or chain stay on one side of at least one sprocket of a bicycle and used for controlling a rear chain gear shift which shifts the position of the chain held on one of the at least one sprocket connected to the rear wheel shaft of the bicycle, and the front gear shift controller being used for controlling a front chain gear shift which shifts the position of the chain held on at least one chain ring connected to the pedal shaft of the bicycle; a shift switch for generating a gear shift signal for the chain gear shift; a signal distributer for transmitting a driving signal between the chain gear shift and the shift switch; a battery for driving the chain gear shift; a rear gear shift wire for connecting the rear chain gear shift and the rear gear shift controller; a front gear shift wire for connecting the front chain gear shift and the front gear shift controller; and a power line for connecting the chain gear shift, the shift switch, the battery, and the signal distributer to each other.

The invention relates to a preparation method of active extract of Juniper siberia and active cosmetics for whitening and antiaging. Siberian juniper is processed through drying, crushing, extraction, decolorization, separation and purification, concentration and other steps to obtain a moderately polar active extract, which is then added to cosmetics to prepare cosmetics with whitening and anti-aging functions. The active ingredient is a medium-polar active ingredient obtained by screening the extract of Juniper siberia for its activities of inhibiting tyrosinase, anti-oxidation, and scavenging free radicals. It has special effects of whitening, water-locking, and anti-aging. Has a certain antibacterial effect. The raw materials used in the present invention are natural organisms and renewable resources; the preparation process is green and safe, the steps are simple and unique, the obtained extract has good stability and long-lasting efficacy, and can be directly added to cosmetics at any stage without worrying about solvent residue and microbial contamination And other issues.
