阻碍物

That bodies should be lent us, while they can afford us pleasure, assist us in acquiring knowledge, or doing good to our fellow creatures, is a kind and benevolent act of God -- when they become unfit for these purposes and afford us pain rather than pleasure -- instead of an aid, become an incumbrance （=encumbrance）妨碍、阻碍、阻碍物、累赘 and answer none of the intentions for which they were given, it is equally kind and benevolent that a way is provided by which we may get rid of them.

上天赐给我们躯壳，让我们享受生活的乐趣，帮助我们求得知识，让我们为人类造福，这都是上帝对我们的大恩大德。当我们的躯体无法达到这些目的，不能给我们快乐，反而给我们痛苦，非但无法帮助我们，反而成为了我们的累赘时，当它们完成不了上帝当初交托给它们的那些使命时，上天准备了一个办法，让我们摆脱它们；这同样也是上帝的恩德。

Data analysis and simulation indicate that longitudinal ultrasonic guided wave can be applied to the on-line distance detection of the pipelines covered or sheltered by barriers.

The ability of melanoblasts in the Silkie embryos to migrate ventrally is correlated with a lack of peanut agglutinin binding barrier tissues, which are present in the Lightbrown Leghorn embryos.

丝羽乌骨鸡的黑色素母细胞之所以可以移动至腹部是由於其缺少了神经阻碍物分子，而此神经阻碍物分子在棕色来航鸡的胚胎发育过程中，会明显地形成一道障壁以抑制神经嵴细胞和黑色素母细胞入侵胚胎腹部。

In order to investigate the effect of upstream barrier on the spicing of Bmdsx, we constructed splicing system in vitro.

为了研究Bmdsx上游阻碍物对Bmdsx拼接的影响，我们建立体外剪接实验体系来进行验证。

Part three mainly explores therelationship between risk bearing and concerning systems,putting forward opinions such as that iffault guarantee liability of goods is not the obstacle of the transference of risk bearing,transference of risk bearing is not the obstacle of fault guarantee liability of goods;if the sellerdelivers the object to the delivery place according to the contract or the legal provisions while thebuyer does't accept the goods according to the agreement,or the goal of contract can't beachieved because that the object's quanlity can meet the requirement of the contract,the buyerrefuses to accept the object or rescinds the contract,the occupant has the obligation to keep it ingood condition and prevent the enlargement of damage or ease the damage according to theprinciple of good faith.

第二节，主要探讨了风险负担与相关制度的关系。如认为物的瑕疵担保责任不阻碍风险负担的移转，风险负担的移转亦不排斥物的瑕疵担保责任；在出卖人按照约定或依照法律的规定将标的物置于交货地点而买受人违反约定没有收取时，或者因标的物质量不符合质量要求，致使不能实现合同目的的，买受人拒绝接受标的物或解除合同的，货物的占有者或代为保管者基于诚实信用的原则应尽妥善保管的义务，防止损害的扩大或减轻损害。

If you're building a chimney, use non-combustible materials and make sure the top of the chimney is at least two feet higher than any obstruction within 10 feet of the chimney.

假如你正在建造一座烟囱，使用不可燃物质并确认烟囱的上方至少超过烟囱附近10范围内任何阻碍物2呎高。

Water, as it comes in contact with different obstructions, can actually hold objects.

那些对流水运动动力熟悉的人知道当它接触到其他不同的阻碍物时，水可能会有困住物体的力量。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
