The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.

The computational formula of dew point temperature was presented according to the physical feature of water vapor such as Michell's saturated water vapour pressure formula. Surface temperature inside wall body was also calculated. Then the comparison between them verified whether wall body has dew. At the same time, the temperatures of every material layer inside wall body were calculated. The partial pressures of saturated water vapour and actual partial pressures of water vapour for every material layer inside wall body were obtained. The two were compared so as to verify whether condensation appears inside wall body.

Results: MR demonstrated capsule wall and papillary solid lesions in one case with cystic and solid lesions of hepatobiliary cystadenoma. Poly cystic form tan if different sine in sew case, capsule wall and septation was thick, part of capsule wall was obviously thickened and nodes form, intrahepatic bile duct was dilated, large poly-antrum cystic keen form structure in one case, capsule wall and septation were smooth, part of capsule wall was uniformly thicken, capsule wall, septation, mural nodus form and solid lesions in three cases wee all slightly hyperintense on T2WI and slightly hypointense on T1WI. Part of cyst fluid was hypointense on T2WI the diameter if tumor ranged from 3.4cm to 13.5cm. Part of capsule wall, septation, solid lesions and mural nodus west obviously enhanced in arterial phase in three cases, the extent of enhancement showed a little degrade in port vein phase, balance phase and delay phase, but dense to liver parenchyma at synchronization.

It is embodied concretely:(1) With the adoption of grouting bolts, the cranny in wall rocks can be blocked up, the air can be isolated, the wall rocks can be prevented to be weatherized and make water, the strength of wall rocks can also be avoided to be lowered;(2) The lax broken wall rocks are commentated to a whole by liquid after they were grouted and the rock"s strength is increased, so the wall rocks become a part of the support structure by using itself and become a whole with the original rock, and the roadway is made to keep stable but not easy to be broken;(3) The spray layer wall are filled with liquid after grouting, the stress is avoided to be concentrated because the load could be evenly acted on the spray layer and the support;(4) The pressure acted on the plank can be delivered to the two sidepieces and then to the bottom by reinforcing the sidepiece; At the same time, the concentration degree of loads acted on the motherboard can be weaken because of the enlargement of the combination arch"s thickness, as result, the rock"s stress is lowered and the heaving is alleviated;(5) The common bolt is made to be fixed the whole length after grouting, the layers are connected to a integral whole and bear the weight of loads, so the support structure"s unity is increased.

Through block wall experimental study we can find out that cracks would appear late and the load of crack-resisting and limit-resisting are increased obviously by the constructional measures in the wall. It is very effective method that the splayed cracks are controlled by sill ring beam, the horizontal bending cracks are controlled by structural column on the side of the wall and the horizontal cracks on the top of the wall are controlled by the whole ring beam. It is the most effective method that wall cracks are controlled by structural column, crout column and sill ring beam.
