不规则性

RESULTS:① No obvious sight defect was detected with the quantitative detection of automatic sight apparatus.② ECT cerebrospinal fluid imaging thought that proximal frontal sinus of right cerebral frontal lobe was the leakage, and the liquid glucose in nasal cavity was quantitatively confirmed to be cerebrospinal fluid.③ Cranial CT showed that cleft could be observed in bilateral frontal lobe and lateral ventricle, low-density gas shadow could be observed in cisterna ambiens, cortex of frontal bone was discontinuous, and bone matrix was trapped.④ ECG showed that right forehead and temple had irregular slow wave, and attack of θ wave. Brain topographic mapping showed that the δ power value of right forehead was increased.⑤ EPQ: The scores of extraversion-introversion, neuroticism, psychoticism and lie were 55, 55, 80 and 50 respectively;⑥ MMPI: The code showed a mode of 69/96, indicating that the brain organ tended to paranoid schizophrenia.

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.

解剖学的研究加深了对G-型输水管胞的认识 1）验证了管胞次生壁分两个阶段形成的理论（Bierhorst，1960），即先后形成不连续的纤维质层和连续的木质化层，前者易被分解，后者抗侵蚀性强；2）证明管胞纤维质的初生壁和次生壁不具穿孔，Hsüa管胞的木质化次生壁具有不规则的简单穿孔，而不是纵列的纹孔（Li，1992）；3）Hsüa reflexa和Huia gracilis的穿孔铸体可代表木质化次生壁的厚度；4）G-型管胞壁层结构具多样性，植物属一级的分异主要表现在次生壁穿孔的分布、孔腔形状和结构的不同；5）某些G-型管胞的穿孔在其分布、密度和孔径方面可兼有S-型管胞的特征。
