If one of the parent had experienced harelip, the incidence will reach 2.6%- 5.6%, which is higher 15 to 32 times than the normal.

父母一方是唇裂的，其子女的发病率可高达2.6%-5.6%，比前者高出15-32倍。

Denmark researchers found in 1500000 birth-records that the risk of suffering harelip of the neonate who is born by a 40-year-old mother is higher than the risk of the same disease of the one who is born by a 30-year-old one.

丹麦研究人员对150万名新生儿的出生档案进行调查发现，40岁母亲与30岁母亲相比，新生儿患兔唇的风险要高20%；而20岁到50岁之间，父亲赌年龄每大10岁，新生儿患兔唇的风险就增加12%。

This paper, based on the fact that the students are more competent in reading and listening than in writing and speaking, analyzes how language input and language output are going on in the institutions of higher learning in China. It points out that language input and output must be balanced. With Jeremy Harmer's theory, it stresses the importance of practice in language output.

针对中国高校学生大学英语学习时阅读和听力能力大於写作和会话能力的实际，依据Jeremy Harmer关於语言输入与输出的理论，分析了中国高校大学英语教学中语言输入与输出的现状，指出语言输入与输出必须平衡，强调了加强语言输出的重要性。

The Poly Vinylidene Fluoridemembrane was chosen to produce ultrasonic in transducer due to its higher sensitivity and better flexibility than other piezoelectric material.At the mean time,harmonic analysis to the PVDF film vibration was performed using ANSYS.The results show that the PVDF membrane can produce an ultrasound with afixed resonance frequency.

对各种压电材料进行比较分析，得到聚偏二氟乙烯膜比其它材料具有更高灵敏度和更好柔韧*，通过对其振动特*进行有限元分析，得到PVDF膜在固定频率具有振幅最大值，可知PVDF膜更适合做声频定向超声波传感器的振动膜来进行声音传播的方向控制。

The checking results of field data shows that the calculation accuracy of THD is relatively higher and the calculation error of harmonic ratio is not more tha.

对现场实测数据的验算结果表明，所提方法对总谐波畸变率的计算精度较高，对各次谐波含有率的计算误差在4%以内。

The harmoniousness of the students work is of great significance to the harmonious development of individual students, the internal harmony of the institutions of higher education and external social harmony.

高校学生工作是高校工作的重要组成部分，学生工作的和谐发展对于大学生个体和谐、高校内部和谐以及高校与外部社会的和谐具有重要意义。

The smart card system is due to an application of RFID, the first scheme of our research is using this to help store the information of authentications. It uses hashing function combined with smart card to the network authentication for the most part to cut down the cost of computation as well as communication and further accomplish higher security.

智慧卡属於射频辨识的一种应用，本研究的机制一为使用智慧卡系统辅助储存认证用资讯，并采用杂凑函数结合智慧卡的方式来进行网路认证，以降低计算与通讯的成本，并达到高度安全性。

However, the eggs of Tibetan chicken can maintain higher hatchability when incubated at high altitude.

以上结果说明藏鸡在高原能够维持较高的孵化率虽然与母鸡饲养环境有关，但主要是遗传的影响。

In chronic exposure, significant changes in length, weight and cumulative mortality rate of fish was observed at concentrations higher than 0.4mgL^(-1) but no effect on hatchability.

慢性暴露中，对孵化时间影响的最低可观察效应浓度LOEC(下标 30d为0.1mgL^(-1)；暴露于0.4mgL^(-1)的高锰酸钾对30d后日本青鳉的体长、体重、累计死亡率均有显著影响，但对孵化率率无显著影响。

In chronic exposure, significant changes in length, weight and cumulative mortality rate of fish was observed at concentrations higher than 0.4mg·L-1, but no effect on hatchability.

慢性暴露中，对孵化时间影响的最低可观察效应浓度（LOEC30d）为0.1mg·L-1；暴露于0.4mg·L-1的高锰酸钾对30d后日本青鳉的体长、体重、累计死亡率均有显著影响，但对孵化率率无显著影响。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
