Because more than 75. 4% regions were occupied by heterochromatin on the sex chromosomes of spiny eel, its X library should be a good tool to isolate the heterochromatic highly repetitive sequences DNA and study its origin and evolution.

在刺鳅的性染色体上，75.4％以上的长度都是异染色质区域，因此，刺鳅X染色体文库也为分离获得鱼类性染色体上异染色质重复序列，探讨其起源和进化规律提供了良好的实验材料。

These sequences possessed highly copy number in the genome and were named as RMX1-6 individually. When these sequences were hybridized to chromosomes of spiny eel, RMX6 was proved to be sex chromosome specific and it only located in heterochromatic regions.

在随机挑取的三百多个克隆中，分离得到了6个高度重复序列，它们在基因组中存在较高拷贝数，按照发现顺序分别命名为RMX1—6(Repetitive sequence inMicrodissected X chromosome)。

A total of 129 children were enrolled in the study. Thirty-eight of the children were switched to tacrolimus monotherapy for different reasons [steroid resistant graft rejection (n = 15), chronic rejection (n = 5), severe acute rejection (n = 4), repetitive acute graft rejection (n = 5), dysfunction of the transplant (n = 3), insufficient CsA metabolism (n = 3), hypertrichosis (n = 2), and CsA toxicity (n = 1)], four patients had primary tacrolimus therapy, and 87 patients are receiving cyclosporine.

其中38名儿童因各种原因单独使用他克莫司治疗[激素型排斥反应(15例)、慢性排斥反应（5例）、严重急性排斥反应（4例）、急性重复排斥反应（5例）、移植肝失功能（ 3例）、环孢素代谢不足（3例）、多毛症（2例）、环孢素毒性（1例）]，4例患者使用他克莫司治疗，87例使用环孢素。

Based on average current mode, PI control adopts the same double loop structure as analog control; Repetitive control adds a feedback innerly to change the model of control object so that it can meet the requirements of stability. This equals to a three-loop structure.

PI控制的设计基于电流平均模式，与模拟控制的双环结构相似；重复控制的设计，内部增加一个负反馈，以改变控制对象的模型，使之满足重复控制的稳定性要求，相当于一个三环控制结构。

Subgrade structure, as the main structure of railway construction, should have enough carrying capacity and deformation resistance capacity, can stand repetitive strength of the vehicle load without structural destruction and excessive sedimentation and deformation, meanwhile, it should have preferable penetration resistance capacity and water stability, to reduce water immersion and intenerate effect, therefore maintaining long time stability of the subgrade.

作为铁道建筑主体构筑物的路基结构，应具有足够的承载能力和抗变形能力，能经受车辆荷载的反复作用而不产生结构性破坏和过量的沉降变形，同时还应具有较好的抗渗透性和水稳定性，降低水的浸入及软化作用，保证路基长期处于稳定状态。

He quoted Schultz's study in which he examined 400 primate skeletons without finding any cases of spondylolisthesis, as evidence that bipedal posture is a factor that contributes to this condition.3 The idea that repetitive stress increases an individual's risk of isthmic spondylolisthesis is also supported by studies that show an increased risk of pars defects in athletes who participate in sports involving hyperextension, such as gymnastics,4 diving, wrestling, and weight-lifting.5

他引用了Schultz的研究，他检查了400个灵长类的骨骼，没有一例脊椎前移，这个发现成了双足站立姿势是导致这种疾病的因素的证据。3运动员，尤其是从事需要过伸腰部的运动，如体操4、跳水、摔跤和举重5的运动员发生峡部不连的风险增加，这也支持了反复应力增加了发生峡性脊椎前移风险的观点。

Mechanical loading of cadaveric vertebrae in a manner which mimics forces on an upright spine has been shown to cause pars interarticularis fractures.14 Bipedal posture in combination with additive stress on the lumbar spine due to repetitive flexion and extension appears to have a major role in the development of isthmic spondylolisthesis.

在尸体椎体上模拟对垂直脊柱的机械负荷可以造成峡部的骨折。14双足站立姿势加上反复屈伸对腰椎产生的应力，这似乎是造成峡性脊椎前移最主要的原因。

In his article When Good Spreadsheets Go Bad, Kugel finally makes his thinking clear. He writes,"Ventana Research strongly advises companies to eliminate standalone spreadsheets in all collaborative or repetitive enterprise-wide finance functions such as budgeting and planning."

在kugel的&什么时候好的电子表格走向不好&的文章中，他最终阐述清楚他的观点，他写到，Ventana Research极力建议在合并或者重复性企业级别财务工作，如预算和预测，公司消除单机版电子表格。
