挖洞

This paper mainly discusses the overset mesh pre-processing technology, and supplies a new efficient and robust hole-cutting algorithm applied in the overset mesh preprocessing, which is based on maze algorithm and can be easily implemented with low complexity.

本文主要讨论重叠网格预处理方法，并提出迷路算法应用于"挖洞"过程，为重叠网格预处理提供了高效、可靠的"挖洞"方法，算法复杂度低，实现简单，健壮性好；在多层次嵌套重叠方面，引入了重叠网格主从关系图有效解决多层次嵌套重叠带来的问题；在提高找重效率方面，建立基于网格的kd树加快了找重过程。

Another carry-over from their hunting instincts is their love of digging, and if left unsupervised, they can often be found digging for grubs in your lawn.

另为一个他们捕猎本性的遗留物就是他们喜欢挖洞，如果他们在没有监督的情形下，它们统称会被发现在你的草坪上挖洞。

It creates demands for shovels and overalls, and puts money into the pockets of the diggers.

因为这增加了对挖洞工具和工作服的需求，钱自然也流入了挖洞者口袋。

If you keep your lacertas outdoors, make sure to put an underground wall around their enclosure both to prevent the lacertas from digging their way out and to prevent moles from digging their way in.

Geomancers other question left, crowds of杨侍郎Shu said: I selected piece of graves, in the open wells have cereal foot deep below, if you can get a bucket of grain is rich in a can Paul杨侍郎a generation of wealth官至公侯, Chuo杨侍郎Shu Feng Shui for the technology has been very impressed, after listening to the words immediately, together with Shu crowds to the capital, came to Shu chaor searching the cave, the people down to continue opening hole, when digging deep to七尺, they found a small hole, and then gently opening there are nearly二尺Founder large穴洞, there are seven穴洞, Badou as much as it may shape cereal objects.

待别的风水师走后，舒绰对杨侍郎说道：我选定的那块墓穴，在开井五尺深以下会有谷物，若你能得到一斗谷物，便是富地了，能保杨侍郎一家世代富贵官至公侯，杨侍郎对于舒绰的风水技术已是十分折服，听完此话后，当即与舒绰一道前往京师，来到舒绰所寻的穴地，令人往下继续开穴，当挖至七尺深时，发现一个小孔，再轻轻挖开里面有近二尺方正大的穴洞，穴洞里面有七、八斗之多，外形很似谷类之物。

Solitary roosters shelter in dense vegetation or enter a cavity horned larks dig holes in the ground and ptarmigan burrow into snow banks but the effect of sheltering is magnified by several birds huddling together in the roots, as wrens, swifts, brown creepers, bluebirds, and anis do.

孤独的雄鸡躲避在茂盛的植被下或进入洞穴躲藏，如角状的百灵在地面挖洞躲藏和松鸡在雪岸挖洞躲藏，但是象鹪鹩、雨燕、褐色的爬行动物、蓝知更鸟和anis所做的一样，由于多只鸟一起拥挤在根茎下，所以躲避的效果被扩大。

The first shot I made among these creatures, I killed a she-goat,which had a little kid by her, which she gave suck to, whichgrieved me heartily; for when the old one fell, the kid stood stockstill by her, till I came and took her up; and not only so, butwhen I carried the old one with me, upon my shoulders, the kidfollowed me quite to my enclosure; upon which I laid down the dam,and took the kid in my arms, and carried it over my pale, in hopesto have bred it up tame; but it would not eat; so I was forced tokill it and eat it myself.

十二月十日我本以为挖洞的工程已大功告成，可突然发生了塌方。也许我把洞挖得太大了，大量的泥土从顶上和一旁的岩壁上塌下来，落下的泥土之多，简直把我吓坏了。我这般惊恐，当然不是没有理由的。要是塌方时我正在洞内，那我肯定用不着掘墓人了。这次灾祸一发生，我又有许多工作要做了。

December 10th, I began now to think my Cave or Vault finished, when on a Sudden,(it seems I had made it too large) a great Quantity of Earth fell down from the Top and one Side, so much, that in short it frighted me, and not without Reason too; for if I had been under it I had never wanted a Grave-Digger: Upon this Disaster I had a great deal of Work to do over again; for I had the loose Earth to carry out; and which was of more Importance, I had the Seiling to prop up, so that I might be sure no more would come down.
