The results show that: Basic density,tracheid length,tracheid width and the ratio of the tracheid length and width increase from core to bark; basic density has a small decrease from base to top,but the change is not significant;The tracheid length,tracheid width and the ratio of the tracheid length and width increase step by .step from the base up to certain height and then decrease by degrees.

基本密度自树干基部向上呈减小趋势，但变化不大；管胞长度、管胞宽度及管胞长宽比自树干基部向上呈&小—大—小&的变异规律；木材的化学成分含量和PH值除抽提物含量随着树高的增加而下降外，其它指标在树高方向上的变化未呈现明显规律性。

But they still pay a fraction of the sums trousered each year by American executives. According to Hay Group, a management consultancy, the median European executive earns just 40% as much as his equivalent in America.

尽管如此，也只有美国高管巨额薪酬的一部分，根据 Hay Group-一家管理咨询机构，欧洲中等水平的高管薪酬仅相当于美国同级别高管的40%。

1MM GTP was mixed with tubulin (2mg/ml) and varying concentrations of sodium selenite. The mixture was incubated at 37℃ for 1hr. MTs were separated from unassembled tubulin by centrifugation. Both supernatants and pellets were subjected to SDS-PAGE.

其中一组实验是在相同的微管蛋白体系中加入不同浓度的亚硒酸钠，然后加入GTP，37℃聚合，离心，沉淀为聚合的微管，而上清液为未聚合的微管蛋白。

Results:Fitfilling 392 Root canals(92.24%),underfilling 23 root canals(5.41%),abovefilling 10 root canals.

结果：适充392个根管（92.24%），欠充23个根管（5.41%），超充10个根管（2.35%）。

In this article,the author provides a complete solution of network management information transmission between OptiX Metro5000 of Huawei and Unode WBM of NEC,which is to modify the mapping of D bits in SDH of OptiX Metro5000,reversion treatment,and finally to realize transparent transmission of two network ma.

为了使华为的OptiX Metro5000和NEC的WBM光设备混合组网后，其各自的网管信息能到达通信调度的网管终端，文章简单介绍了通过华为OptiX光设备SDH的D字节的映射、还原处理，实现了各自网管信息的透传。

The changes include:(1) Put the urediniospores into the tube with two steel balls and 1. 6 g/L Chelex-100,the uredinia may be picked up with airing host tissues.(2) Add KOH into the extraction buffer instead of NaOH and vortex the tube violently for 30 min.(3) Prick a hole under the bottom instead of picking out of the steel balls, then centrifuge the tube to toss the liquid into the sheathed tube.

改进的 内容包括：(1)在有二钢珠和1.6 g／L Chelex的离心管中加入夏孢子，夏孢子可以来自带有风干寄主叶肉组织的夏孢子堆；(2)在离心管中加入KOH而不是NaOH，然后剧烈斡旋30 min；(3)将离心管管底穿一小孔，套上一新离心管，短暂离心甩出内容物。

Ureteroscopy was applied to treat 1200 cases which incelluded ureteral stones in 1010 cases (146 cases in upper, 344 cases in middle. 520 cases in lower),ureteral strictures in 18 ureteral double catheter stagnation in 38, urethral stricture in 38, bladder calculi in 41, pelvis calculi in 8, ureterovaginal fistula in 5 and others.

其中行输尿管镜治疗者1200例，包括输尿管结石1010例，其中上段结石146例、中段344例、下段520例；输尿管狭窄18例；医源性双J管滞留38例；男性尿道狭窄38例；膀胱尿道结石41例；肾盂结石8例；输尿管阴道漏5例；小儿逆行输尿管插管20例；内支架管置入22例。

Abstract］ Objective To evaluate the role of stomach catheter as urethra stent and drainage tube in urethroplasty in hypospadias.

摘要］ 目的评价单纯用胃管兼作尿道支撑管和引流管在尿道下裂尿道成形术中的作用。

It is effective that stomach catheter act as urethra stent and drainage tube in urethroplasty in hypospadias,need not urinary diversion.

在尿道下裂尿道成形术中单纯用胃管兼作尿道支撑管和引流管引流尿液是充分有效的，无须另行尿流改道。

This paper analyzed and compared the common tap effluent phenomena, functioning waterhead, discharging capacity in the hydrotechnics according to calculation theories of pipe outlet, showing significance of pine outlet in practical application.

本文根据管嘴出流的计算理论，分析比较了水利工程中常见几种管嘴出流的水流现象、作用水头、泄流量，对管嘴在实际工程中的应用具有一定的现实意义。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
