In order to getting the accurate and objective confidence and deep clairvoyance, this paper concretely discusses LiZhi .

Determination of the critical exposure and the penetration depth of the photosensitive resin for Stereolithography;

Combined with the relationship between evanescent wave penetration depth and incidence angle,a new parabola taper fiber probe is put forward.

According to the relationship between the penetration depth of the evanescent wave and the incident light angle,with the inner face kf probe to the effect of the light reflection angle,a new parabola taper fiber is put forward and compared with different tape.

Study on penetration depth of cement-based capillary crystalline waterpro of materials with SEM and EDAX;

Microscopic analysis is made on cement based permeable crystallization type waterproof paint and study is made on chemical reactions taken place when active ingredient of the paint penetrated into the concrete and on penetration depth of crystalloid product and active ion that may create by reaction using XRD and SEM.

The base properties of five offset paper was measured,and the penetration depth,after printing,was tested when the same ink enter into these paper.

The penetration depth at 0 K can be attained as: λ0=265 nm for YBCO/LAO and λ0=280 nm for YBCO/MgO.

The results show that the maximum penetration depth of gas flow is increased with the increase of gas momentum while the diameter of oxigen gunjet keeps constant.

According to Maxwell equation and HagenRuben formula, the absorptivity and the penetration depth in metal of Nd:YAG laser(1.

The article is focused on the penetrating process,penetrating depth,penetrating concentrate of the active chemical substance hydrated production,the SiO32-ion,of the capillary crystalline waterproofing coatings in the base concrete in standard test condition,which is described in the GB 18445,by the way of analyzing the dates getting from the chloride ion corrosion on the concrete.
