Abstract: A portable fruit picker with an adjustable height comprises a picking module and a container part, wherein the picking module comprises a picking part and a supporting part, and the picking part comprises a collecting part, a grabbing part and a conveying part which are engaged with the collecting part; the conveying part has elastic characteristics; the supporting part comprises a plurality of detachably connected supporting bodies; the container part is provided with a fixing part. The user can adjust the height of the supporting part independently through the detachably connected supporting bodies, and the container is provided with the fixing part, so that the user can fix the container on himself.
Abstract: An in-situ evaluation method and system for loess collapsibility based on non-destructive time-domain reflection technology, includes: calculating loess dry density and mass water content; considering loess dry density, mass water content and basic physical property indicators, and evaluating loess collapsibility in situ through mathematical models. The loess collapsibility in-situ evaluation method based on the non-destructive time domain reflectometry technology of the present invention can not only realize whether the loess has collapsibility, but also has the potential to distinguish strong, medium and slight collapsibility.

Abstract: The problem to be solved is to provide a boron nitride particle stably and efficiently with a high organic modification ratio. To solve the problem, the continuous production method according to the present invention comprises contacting step for continuously supplying a boron nitride with pretreatment and an organic modifier to continuously contact them with an aqueous material in a subcritical state in a presence of an acid or a base. The pretreatment comprises any one or more kinds selected from adding an acid to the boron nitride, adding a base to the boron nitride, adding an oxidant to the boron nitride, adding a reductant to the boron nitride, and conducting a hydrothermal treatment or a solvothermal treatment to the boron nitride.
