Second, we think about the Conjecture(Conjecture8.7,Conjecture8.23;[2]Conjec-ture2.3) and prove that some particular ideals have the same graded Betti numbers via shifting operations,that s,.if is a simpcial complex and I is a monomial ideal generated in one degree,we have that...

后一部分的主要结论是：针对J.Herzog提出的猜想([1]猜想8.7，猜想8.23；[2]猜想2.3)，证明了当I_Δ为同一次数生成元生成的稳定理想时，对i，j，有β_=β_。当I_Δ为无平方分量线性理想，特别地当I_Δ是弱稳定理想时，对i，j，有β_=β_=β_。

Create calculations to use in the Graph to find the slope of the best fit line of 'distance doubled' and 'time squared'.

创建一个计算式，用于图表中，以找出&距离的两倍&——&时间的平方&的最佳拟合直线的斜率。

Just upstream from the town of Del Rio is a dam that holds back water from the Rio Grande and two other rivers to form the 263 square-kilometer reservoir called Lake Amistad .

戴尔李欧镇上游处有一座水坝，其水源有二：一为李欧河，再者为源自鄂米斯达湖的两条河，此湖面积达263平方公尺，宛如一座储水池。

This excellence of grace is not only mentioned countless times in Holy Writ (Romans 8:15 sq.; 1 John 3:1 sq., etc.), but is included in the Scriptural idea of a re-birth in God cf. John 1:12 sq.; 3:5; Titus 3:5; James 1:18, etc.

这个卓越的宽限期，是不是只提了无数次，在神圣的令状（罗马书8：15平方米；约翰一3：1平方等），但也包括在圣经的想法重新出生在上帝（参见约翰1：12平方米； 3时05分；弟兄3时05分；詹姆斯1：18 ，等等）。

Sir Isaac Newton's magnificent "inverse-square law" is correct in the calculation of magnitude.

牛顿爵士辉煌的&平方反比定律&对力的大小的计算是正确的。

The distance between the eastern and western sides extends over 1800 meters, and the total length of the southern city wall measures about 2000 meters and became a city protected from all sides; by the city walls in the east, west and south, and by the Yazi River in the north.

复原后的三星堆古城平面略呈北窄南宽的梯形，城东西长度在1800米以上，南城墙长约2000米，城内面积达3.5平方千米，形成了由东、西、南三面城墙及北侧鸭子河为防御体系的古城。

The result showed that the strong storm followed by mesoscale squall line was primary cause of strong sandstorm producing, steps and ladders short wave trough of 500 hPa was great criterion triggering system for the mesoscale squall line producing, the essential dynamic condition was provided by distortion field and the mesoscale low pressure of 700 hPa for the strong sandstorm forming and maintaining in mid-west of Hexi Corridor, the deep vertical circulation development condition was basic power that urged squall line to occur and sand dust to curl up, which was provided for the deep convection development by superimposition of lifting movement before ground cold front and ascendant current of secondary circulation in upper air jet entrance region, temperature and the barometric gradient around the cold front was enlarged by enhancement of ground thermal low and temperature diurnalvariation of afternoon, by which essential thermal energy unstable condition was provided for the gale and strong sandstorm eruption, the strong sandstorm appeared in downstream of -200 m^2s^(-2) center of vertical helicity, the vertical helicity had good instruction significance for development of squall line and landing region of sandstorm, the mesoscale squall line occurred in unstable stratification, basic condition of potential energy transforming as kinetic energy was provided by strong unstable stratification for the strong sandstorm forming and developing.

结果表明：中尺度飑线所伴随的强风暴是产生强沙尘暴的主要原因；500 hPa阶梯短波槽是中尺度飑线产生的大尺度触发系统，河西走廊中西部700 hp变形场、中尺度低压为强沙尘暴形成和维持提供了必要的动力条件；地面冷锋前上升运动与高空急流入口区次级环流的上升气流的叠加，为深对流发展提供了深厚的垂直环流发展条件，是促使飑线发生和沙尘卷起的基本动力；地面热低压的加强和午后气温的日变化加大了冷锋前后的温度和气压梯度，为大风、强沙尘暴爆发提供了必要的热力不稳定条件；强沙尘暴出现在垂直螺旋度为－200平方公尺/s^2中心的下游，垂直螺旋度对飑线的发展和沙尘暴的落区具有较好的指示意义；中尺度飑线发生在不稳定层结内，较强的不稳定层结为强沙尘暴形成、发展提供了位能转化为动能的基本条件。

It would be better if there were but one inhabitant to a square mile, as where I live.

如果距离我居住的地方方圆一平方哩只有一户居民的话，会更好。

For example, the United States is the fourth most populous country, but in 2005 it had a population density of only 84 people per square mile.

例如，美国是世界上人口第四多的国家，但在2005年人口密度只有每平方英哩84人。

A population of 305.4 thousand, an average of about 97 people per square kilometer.

人口为30.54万人，平均每平方公里约97人。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
