Abstract］ objective to investigate anus sphincter preserved surgical method and indication for low rectal cancer.methods 15 cases with low rectal cancer were operated with eversion and pull-through anus preserved colorectal anastomosis through anus.results no patients died of operation,no patients was with fistula and stricture of anastomosis,no defecation incontinence happened after postoperative 20 weeks,only one patient was with local recurrence.following up for 8 months to 5 years,5 cases were with distant metastasis,4 of these died,one of these had lived with liver metastasis for 3 years.conclusion the indication of anus preserved operation should be chosen according to clinical stage and biological characteristic of rectal malignancy; eversion and pull-through anus preserved colorectal anastomosis through anus is a better anus preserved operation for low rectal cancer.

目的 探讨低位直肠癌保留肛门括约肌功能的手术方法和手术适应证。方法对低位直肠癌经腹经肛门直结肠外翻拉出保留肛门吻合术15例。结果全组无手术死亡，未发生吻合口漏和吻合口狭窄，局部复发1例，20周左右恢复正常排便排气功能，无大便失禁病例。随访8个月～5年，5例为远处转移，死亡4例，其中1例肝转移3年仍生存。结论根据直肠癌的临床分期和肿瘤的生物学特性选择保肛手术适应证，经腹、肛门齿线上直肠癌根治性切除，行肛门直结肠外翻拉出吻合是低位直肠癌较好的保肛术式。

1 Filling amount: 30 tons of bamboo counted with liquor filled tank and circularly press the bamboo flakes for 3-4 minutes during boiling,(the data results from repeated experiments), if the filling amount is too less, the hardness is low, too much alkali remnant, and the pulp yield will be low; if the filling amount is too much, the cooking liquor can not be dried completed, and the circulation amount is too less, the electric current of circulating pump is too low, it will be difficult to cook, and there will be too much pulp knots with high hardness and less alkali remnant which may lead to unripe pulp.

3.1.1装锅量：竹子30吨是以液浸装锅和开中循环压竹片3——4分钟为计，（数据是根据多次实验得出的结果）如装锅量太小，硬度低，残碱大，浆得率低，装锅量太大蒸煮液无法完全送完，循环量小，循环泵电流小，蒸煮困难，浆节子多、硬度高、残碱小，有可能造成生浆。

High temperature is favorable to the formation of low valence state-As minerals and to the addition of As into pyrite crystal lattice, thus is favorable for the formation of P type of pyrite. However, at low temperature, high valence As minerals are easily formed and this case is not suitable for As to add into the pyrite crystal lattice to substitute S, thus the low temperature is beneficial to the formation of N type of pyrite.

As在白然界中的赋存状态与温度的关系表明：高温有利于形成低价态的As矿物，也有利于As呈低价态进入黄铁矿晶格中替代S而形成P型导电；低温则有利于形成高价态As的独立矿物，不利于As呈低价态进入黄铁矿晶格中替代S。，因而有利于形成N型导电。

Also the multi-scale entropy processing and analysis of conductance fluctuating signals acquired by VMEA sensor for five flow patterns with water as the continuous liquid are conducted. The study result indicates that the increase of f o makes oil in water type slug flow occur at lower U sg; for low flow velocity, the continuous liquid inversion occurs at about f o=0.9 and the increase of U sg makes the inversion point move to low oil volume fraction; the multi-scale entropy detail describes the nonlinear dynamic characteristics of oil-gas-water flow patterns and the rate of MSE at low scales sensitively indicates the variation of flow patterns and can act as the efficient criterion of three-phase flow patterns identification.

对水为连续相的5种流型VMEA传感器波动信号进行了多尺度熵分析，研究结果表明：含油率增加可使水包油段塞流在较低气相表观速度下产生；较低流速下的油水相态逆转可发生在油液比为0.9左右，气相流速增加使得逆转点向含油率低的方向偏移；多尺度熵细节可以刻画油气水三相流非线性动力学特性，而低尺度的多尺度熵变化率敏感地反映流型转变，是划分油气水三相流流型的有效准则。
